China manufacturer Industrial Vacuum Pump Air Oil Water Rotary Dry Portable Mini Scroll Reciprocating Diaphragm Centrifugal Positive Displacement DC AC Vacuum Pump wholesaler
Product Description
Industrial Vacuum Pump Air Oil Water Rotary Dry Portable Mini Scroll Reciprocating Diaphragm Centrifugal Positive Displacement DC AC Vacuum Pump
industrial vacuum pumps
Rotary vane: Rotary vane pumps are comprised of a series of vanes that are mounted to a rotor that turns inside a cavity. As the vanes rotate, centrifugal force extends them from their individual slots, forming compression cells that get larger to draw air in from the intake and smaller to push air out the exhaust.
Articulated piston: An articulated piston industrial vacuum pump operates in a manner similar to that of an automobile engine. As the piston moves downward inside the cylinder, air is drawn in through the intake valve. During the piston’s upward stroke, the air is permitted to escape via an exhaust valve. Two spring-backed piston rings are used to seal the piston to the cylinder.
Screw: Rotary screw pumnps include 2 parallel rotary screws in the pump housing. The screws are synchronized to turn in opposite directions, which causes the compression action to occur. The gas is compressed in the direction of the pump’s discharge port.
Liquid ring: Liquid ring pumps also operate via positive displacement. During operation, the pump’s impeller rotates inside the pump casing. A rotating liquid ring then seals the impeller and its blades. Liquid is sucked into the compression chamber to keep the ring stable. Conveyed gas is compressed during each impeller revolution.

Basic knowledge of vacuum pump
A vacuum pump is a device that draws gas molecules from a sealed volume and maintains a partial vacuum. Its main job is to create a relative vacuum within a given volume or volumes. There are many types of vacuum pumps. This article will describe how they work, their types, and their applications.
How it works
A vacuum pump is a mechanical device that removes gas from a system by applying it to a higher pressure than the surrounding atmosphere. The working principle of the vacuum pump is based on the principle of gas transfer and entrapment. Vacuum pumps can be classified according to their vacuum level and the number of molecules that can be removed per cubic centimeter of space. In medium to high vacuum, viscous flow occurs when gas molecules collide with each other. Increasing the vacuum causes molecular or transitional flow.
A vacuum pump has several components that make it a versatile tool. One of the main components is the motor, which consists of a rotor and a stator. The rotor and stator contain coils that generate a magnetic field when excited. Both parts must be mounted on a base that supports the weight of the pump. There is also an oil drain that circulates oil throughout the system for lubrication and cooling purposes.
Another type of vacuum pump is the liquid ring vacuum pump. It works by positioning the impeller above or below the blades. Liquid ring pumps can also adjust the speed of the impeller. However, if you plan to use this type of pump, it is advisable to consult a specialist.
Vacuum pumps work by moving gas molecules to areas of higher or lower pressure. As the pressure decreases, the removal of the molecules becomes more difficult. Industrial vacuum systems require pumps capable of operating in the 1 to 10-6 Torr range.
Type
There are different types of vacuum pumps. They are used in many different applications, such as laboratories. The main purpose of these pumps is to remove air or gas molecules from the vacuum chamber. Different types of pumps use different techniques to achieve this. Some types of pumps use positive displacement, while others use liquid ring, molecular transfer, and entrapment techniques.
Some of these pumps are used in industrial processes, including making vacuum tubes, CRTs, electric lights, and semiconductor processing. They are also used in motor vehicles to power hydraulic components and aircraft. The gyroscope is usually controlled by these pumps. In some cases, they are also used in medical settings.
How a vacuum pump works depends on the type of gas being pumped. There are three main types: positive displacement, negative displacement, and momentum transfer. Depending on the type of lubrication, these principles can be further divided into different types of pumps. For example, dry vacuum pumps are less sensitive to gases and vapors.
Another type of vacuum pump is called a rotary vane pump. This type of pump has two main components, the rotor and the vacuum chamber. These pumps work by rotating moving parts against the pump casing. The mating surfaces of rotary pumps are designed with very small clearances to prevent fluid leakage to the low pressure side. They are suitable for vacuum applications requiring low pulsation and high continuous flow. However, they are not suitable for use with grinding media.
There are many types of vacuum pumps and it is important to choose the right one for your application. The type of pump depends on the needs and purpose of the system. The larger ones can work continuously, and the smaller ones are more suitable for intermittent use. 
Apply
Vacuum pumps are used in a variety of industrial and scientific processes. For example, they are used in the production of vacuum tubes, CRTs, and electric lamps. They are also used in semiconductor processing. Vacuum pumps are also used as mechanical supports for other equipment. For example, there may be multiple vacuum pumps on the engine of a motor vehicle that powers the hydraulic components of an aircraft. In addition, they are often used in fusion research.
The most common type of vacuum pump used in the laboratory is the rotary vane pump. It works by directing airflow through a series of rotating blades in a circular housing. As the blades pass through the casing, they remove gas from the cavity and create a vacuum. Rotary pumps are usually single or double-stage and can handle pressures between 10 and 6 bar. It also has a high pumping speed.
Vacuum pumps are also used to fabricate solar cells on wafers. This involves a range of processes including doping, diffusion, dry etching, plasma-enhanced chemical vapor deposition, and bulk powder generation. These applications depend on the type of vacuum pump used in the process, and the vacuum pump chosen should be designed for the environment.
While there are several types of vacuum pumps available, their basic working principles remain the same. Each has different functions and capacities, depending on the type of vacuum. Generally divided into positive displacement pump, rotary vane pump, liquid ring pump, and molecular delivery pump.
Maintenance
The party responsible for general maintenance and repairs is the Principal Investigator (PI). Agknxs must be followed and approved by the PI and other relevant laboratory personnel. The Agknx provides guidelines for routine maintenance of vacuum pump equipment. Agknxs are not intended to replace detailed routine inspections of vacuum pump equipment, which should be performed by certified/qualified service personnel. If the device fails, the user should contact PI or RP for assistance.
First, check the vacuum pump for any loose parts. Make sure the inlet and outlet pressure gauges are open. When the proper pressure is shown, open the gate valve. Also, check the vacuum pump head and flow. Flow and head should be within the range indicated on the label. Bearing temperature should be within 35°F and maximum temperature should not exceed 80°F. The vacuum pump bushing should be replaced when it is severely worn.
If the vacuum pump has experienced several abnormal operating conditions, a performance test should be performed. Results should be compared to reference values to identify abnormalities. To avoid premature pump failure, a systematic approach to predictive maintenance is essential. This is a relatively new area in the semiconductor industry, but leading semiconductor companies and major vacuum pump suppliers have yet to develop a consistent approach.
A simplified pump-down test method is proposed to evaluate the performance of vacuum pumps. The method includes simulated aeration field tests and four pump performance indicators. Performance metrics are evaluated under gas-loaded, idle, and gas-load-dependent test conditions. 
Cost
The total cost of a vacuum pump consists of two main components: the initial investment and ongoing maintenance costs. The latter is the most expensive component, as it consumes about four to five times the initial investment. Therefore, choosing a more energy-efficient model is a good way to reduce the total system cost and payback period.
The initial cost of a vacuum pump is about $786. Oil-lubricated rotary vane pumps are the cheapest, while oil-free rotary vane pumps are slightly more expensive. Non-contact pumps also cost slightly more. The cost of a vacuum pump is not high, but it is a factor that needs careful consideration.
When choosing a vacuum pump, it is important to consider the type of gas being pumped. Some pumps are only suitable for pumping air, while others are designed to pump helium. Oil-free air has a different pumping rate profile than air. Therefore, you need to consider the characteristics of the medium to ensure that the pump meets your requirements. The cost of a vacuum pump can be much higher than the purchase price, as the daily running and maintenance costs can be much higher.
Lubricated vacuum pumps tend to be more durable and less expensive, but they may require more maintenance. Maintenance costs will depend on the type of gas that needs to be pumped. Lighter gases need to be pumped slowly, while heavier gases need to be pumped faster. The maintenance level of a vacuum pump also depends on how often it needs to be lubricated.
Diaphragm vacuum pumps require regular maintenance and oil changes. The oil in the diaphragm pump should be changed every 3000 hours of use. The pump is also resistant to chemicals and corrosion. Therefore, it can be used in acidic and viscous products.

Can Vacuum Pumps Be Used for Chemical Distillation?
Yes, vacuum pumps are commonly used in chemical distillation processes. Here’s a detailed explanation:
Chemical distillation is a technique used to separate or purify components of a mixture based on their different boiling points. The process involves heating the mixture to evaporate the desired component and then condensing the vapor to collect the purified substance. Vacuum pumps play a crucial role in chemical distillation by creating a reduced pressure environment, which lowers the boiling points of the components and enables distillation at lower temperatures.
Here are some key aspects of using vacuum pumps in chemical distillation:
1. Reduced Pressure: By creating a vacuum or low-pressure environment in the distillation apparatus, vacuum pumps lower the pressure inside the system. This reduction in pressure lowers the boiling points of the components, allowing distillation to occur at temperatures lower than their normal boiling points. This is particularly useful for heat-sensitive or high-boiling-point compounds that would decompose or become thermally degraded at higher temperatures.
2. Increased Boiling Point Separation: Vacuum distillation increases the separation between the boiling points of the components, making it easier to achieve a higher degree of purification. In regular atmospheric distillation, the boiling points of some components may overlap, leading to less effective separation. By operating under vacuum, the boiling points of the components are further apart, improving the selectivity and efficiency of the distillation process.
3. Energy Efficiency: Vacuum distillation can be more energy-efficient compared to distillation under atmospheric conditions. The reduced pressure lowers the required temperature for distillation, resulting in reduced energy consumption and lower operating costs. This is particularly advantageous when dealing with large-scale distillation processes or when distilling heat-sensitive compounds that require careful temperature control.
4. Types of Vacuum Pumps: Different types of vacuum pumps can be used in chemical distillation depending on the specific requirements of the process. Some commonly used vacuum pump types include:
– Rotary Vane Pumps: Rotary vane pumps are widely used in chemical distillation due to their ability to achieve moderate vacuum levels and handle various gases. They work by using rotating vanes to create chambers that expand and contract, enabling the pumping of gas or vapor.
– Diaphragm Pumps: Diaphragm pumps are suitable for smaller-scale distillation processes. They use a flexible diaphragm that moves up and down to create a vacuum and compress the gas or vapor. Diaphragm pumps are often oil-free, making them suitable for applications where avoiding oil contamination is essential.
– Liquid Ring Pumps: Liquid ring pumps can handle more demanding distillation processes and corrosive gases. They rely on a rotating liquid ring to create a seal and compress the gas or vapor. Liquid ring pumps are commonly used in chemical and petrochemical industries.
– Dry Screw Pumps: Dry screw pumps are suitable for high-vacuum distillation processes. They use intermeshing screws to compress and transport gas or vapor. Dry screw pumps are known for their high pumping speeds, low noise levels, and oil-free operation.
Overall, vacuum pumps are integral to chemical distillation processes as they create the necessary reduced pressure environment that enables distillation at lower temperatures. By using vacuum pumps, it is possible to achieve better separation, improve energy efficiency, and handle heat-sensitive compounds effectively. The choice of vacuum pump depends on factors such as the required vacuum level, the scale of the distillation process, and the nature of the compounds being distilled.

Can Vacuum Pumps Be Used for Leak Detection?
Yes, vacuum pumps can be used for leak detection purposes. Here’s a detailed explanation:
Leak detection is a critical task in various industries, including manufacturing, automotive, aerospace, and HVAC. It involves identifying and locating leaks in a system or component that may result in the loss of fluids, gases, or pressure. Vacuum pumps can play a significant role in leak detection processes by creating a low-pressure environment and facilitating the detection of leaks through various methods.
Here are some ways in which vacuum pumps can be used for leak detection:
1. Vacuum Decay Method: The vacuum decay method is a common technique used for leak detection. It involves creating a vacuum in a sealed system or component using a vacuum pump and monitoring the pressure change over time. If there is a leak present, the pressure will gradually increase due to the ingress of air or gas. By measuring the rate of pressure rise, the location and size of the leak can be estimated. Vacuum pumps are used to evacuate the system and establish the initial vacuum required for the test.
2. Bubble Testing: Bubble testing is a simple and visual method for detecting leaks. In this method, the component or system being tested is pressurized with a gas, and then immersed in a liquid, typically soapy water. If there is a leak, the gas escaping from the component will form bubbles in the liquid, indicating the presence and location of the leak. Vacuum pumps can be used to create a pressure differential that forces gas out of the leak, making it easier to detect the bubbles.
3. Helium Leak Detection: Helium leak detection is a highly sensitive method used to locate extremely small leaks. Helium, being a small atom, can easily penetrate small openings and leaks. In this method, the system or component is pressurized with helium gas, and a vacuum pump is used to evacuate the surrounding area. A helium leak detector is then used to sniff or scan the area for the presence of helium, indicating the location of the leak. Vacuum pumps are essential for creating the low-pressure environment required for this method and ensuring accurate detection.
4. Pressure Change Testing: Vacuum pumps can also be used in pressure change testing for leak detection. This method involves pressurizing a system or component and then isolating it from the pressure source. The pressure is monitored over time, and any significant pressure drop indicates the presence of a leak. Vacuum pumps can be used to evacuate the system after pressurization, returning it to atmospheric pressure for comparison or retesting.
5. Mass Spectrometer Leak Detection: Mass spectrometer leak detection is a highly sensitive and precise method used to identify and quantify leaks. It involves introducing a tracer gas, usually helium, into the system or component being tested. A vacuum pump is used to evacuate the surrounding area, and a mass spectrometer is employed to analyze the gas samples for the presence of the tracer gas. This method allows for accurate detection and quantification of leaks down to very low levels. Vacuum pumps are crucial for creating the necessary vacuum conditions and ensuring reliable results.
In summary, vacuum pumps can be effectively used for leak detection purposes. They facilitate various leak detection methods such as vacuum decay, bubble testing, helium leak detection, pressure change testing, and mass spectrometer leak detection. Vacuum pumps create the required low-pressure environment, assist in evacuating the system or component being tested, and enable accurate and reliable leak detection. The choice of vacuum pump depends on the specific requirements of the leak detection method and the sensitivity needed for the application.

Vacuum cooling helps maintain the freshness, texture, and quality of delicate food items such as fruits, vegetables, and bakery products.
4. Vacuum Concentration: Vacuum pumps are employed in vacuum concentration processes in the food industry. Vacuum concentration involves removing excess moisture from liquid food products to increase their solids content. By creating a vacuum, the boiling point of the liquid is reduced, allowing for gentle evaporation of water while preserving the desired flavors, nutrients, and viscosity of the product. Vacuum concentration is commonly used in the production of juices, sauces, and concentrates.
5. Vacuum Mixing and Deaeration: Vacuum pumps are used in mixing and deaeration processes in food processing. In the production of certain food products such as chocolates, confectioneries, and sauces, vacuum mixing is employed to remove air bubbles, achieve homogeneity, and improve product texture. Vacuum pumps aid in the removal of entrapped air and gases, resulting in smooth and uniform food products.
6. Vacuum Filtration: Vacuum pumps are utilized in food processing for vacuum filtration applications. Vacuum filtration involves separating solids from liquids or gases using a filter medium. Vacuum pumps create suction that draws the liquid or gas through the filter, leaving behind the solid particles. Vacuum filtration is commonly used in processes such as clarifying liquids, removing impurities, and separating solids from liquids in the production of beverages, oils, and dairy products.
7. Marinating and Brining: Vacuum pumps are employed in marinating and brining processes in the food industry. By applying a vacuum to the marinating or brining container, the pressure is reduced, allowing the marinade or brine to penetrate the food more efficiently. Vacuum marinating and brining help enhance flavor absorption, reduce marinating time, and improve the overall taste and texture of the food.
8. Controlled Atmosphere Packaging: Vacuum pumps are used in controlled atmosphere packaging (CAP) systems in the food industry. CAP involves modifying the gas composition within food packaging to extend the shelf life and maintain the quality of perishable products. Vacuum pumps aid in the removal of oxygen or other unwanted gases from the package, allowing the introduction of a desired gas mixture that preserves the food’s freshness and inhibits microbial growth.
These are just a few examples of how vacuum pumps are used in food processing. The ability to create and control vacuum or low-pressure environments is a valuable asset in preserving food quality, enhancing shelf life, and facilitating various processing techniques in the food industry.

Soil and groundwater remediation refers to the process of removing contaminants from the soil and groundwater to restore environmental quality and protect human health. Vacuum pumps play a crucial role in various remediation techniques by facilitating the extraction and treatment of contaminated media. Some of the common applications of vacuum pumps in soil and groundwater remediation include:
1. Soil Vapor Extraction (SVE): Soil vapor extraction is a widely used remediation technique for volatile contaminants present in the subsurface. It involves the extraction of vapors from the soil by applying a vacuum to the subsurface through wells or trenches. Vacuum pumps create a pressure gradient that induces the movement of vapors towards the extraction points. The extracted vapors are then treated to remove or destroy the contaminants. Vacuum pumps play a vital role in SVE by maintaining the necessary negative pressure to enhance the volatilization and extraction of contaminants from the soil.
2. Dual-Phase Extraction (DPE): Dual-phase extraction is a remediation method used for the simultaneous extraction of both liquids (such as groundwater) and vapors (such as volatile organic compounds) from the subsurface. Vacuum pumps are utilized to create a vacuum in extraction wells or points, drawing out both the liquid and vapor phases. The extracted groundwater and vapors are then separated and treated accordingly. Vacuum pumps are essential in DPE systems for efficient and controlled extraction of both liquid and vapor-phase contaminants.

Vacuum pumps play a critical role in maintaining the required flow rates and hydraulic gradients for effective groundwater extraction and treatment.
4. Air Sparging: Air sparging is a remediation technique used to treat groundwater and soil contaminated with volatile organic compounds (VOCs). It involves the injection of air or oxygen into the subsurface to enhance the volatilization of contaminants. Vacuum pumps are utilized in air sparging systems to create a vacuum or negative pressure zone in wells or points surrounding the contaminated area. This induces the movement of air and oxygen through the soil, facilitating the release and volatilization of VOCs. Vacuum pumps are essential in air sparging by maintaining the necessary negative pressure gradient for effective contaminant removal.
5. Vacuum-Enhanced Recovery: Vacuum-enhanced recovery, also known as vacuum-enhanced extraction, is a remediation technique used to recover non-aqueous phase liquids (NAPLs) or dense non-aqueous phase liquids (DNAPLs) from the subsurface. Vacuum pumps are employed to create a vacuum or negative pressure gradient in recovery wells or trenches. This encourages the movement and extraction of NAPLs or DNAPLs towards the recovery points. Vacuum pumps facilitate the efficient recovery of these dense contaminants, which may not be easily recoverable using traditional pumping methods.
It’s important to note that different types of vacuum pumps, such as rotary vane pumps, liquid ring pumps, or air-cooled pumps, may be used in soil and groundwater remediation depending on the specific requirements of the remediation technique and the nature of the contaminants.
In summary, vacuum pumps play a vital role in various soil and groundwater remediation techniques, including soil vapor extraction, dual-phase extraction, groundwater pumping and treatment, air sparging, and vacuum-enhanced recovery.
