1. Composition and Overview of WLQ80/one hundred Jetting CZPT

WLQ80/a hundred jetting device is Firm’s mature and steady merchandise, including the program, technology design of stress control and protecting factors, inventory manage of supporting components, item manufacturing, item screening, packaging and shipping, submission and acceptance , complex services, shipping and delivery utilization and on-internet site assistance.
WLQ jetting machine is composed of large strain pump, motor, coupling, tri-star starter management box, reduction valves and protection valves, and many others. It is a necessary maintenance gear to conduct industrial cleaning on the rusty and soiled surface of objects. This device adopts divided head of cylinder liner (national patent, patent No. ZL 95 241067.2), and is characterised by higher pressure, enough circulation, sleek and reliable running and adaptable operation, as nicely as simple servicing, which is “a shining star” between comparable goods.

1. CZPT technique

CZPT system of WLQ jetting device is demonstrated in the diagram.
The complete technique is made up of substantial force pump, aid valve, basic safety valve, foot valve, h2o gun, enter-return flexible hose, water tank and distribution box. In the course of functioning hrs, fresh drinking water injects into h2o tank through versatile hose, and then enters the lower pressure chamber of pump fluid end by way of imbibing filter, imbibing flexible hose and imbibing stop valve. Substantial pressure water is transported to workplaces right after many segments of substantial strain hose. There are two sorts of working problems:
Problem one: It is controlled by the foot valve (h2o gun is not used). This kind of problem is normally used for the cleaning of pipe walls. Foot valve is utilised to control the change.
Condition 2: It is managed by water gun with switches (foot valve is not used). This kind of situation is typically employed for the cleansing of rusty and soiled surface area, as nicely as standard washing. Drinking water gun is utilised to control the change.
A reduction valve is deployed at the higher-pressure outlet of the pump, to alter the real operating force. Abnormal h2o shall return to h2o tank by means of the overflow port at relief valve and liquid return pipe. Pump basic safety valve is also deployed, which can be opened instantly when the pumping force is increased thanks to surprising elements, in buy to protect the pump and motor from shockproof stress gauge and exhibit the operating pressure.
3. Structural description
three.one Jetting machine
Jetting equipment is a system that can change drives of electric powered motor or diesel motor to large pressure drinking water fluid stress vitality. WLQ cleanse water pump belongs to horizontal a few-plunger reciprocating substantial-force pump.
Structures of the pump remember to see the diagram. It mostly is made up of housing assembly, pump head assembly, coupling, bottom bracket, and electric motor or diesel engine.
Three-period four-pole AC motor or diesel engine can push the rotation of a few toss crank shaft through coupling and equipment reducer. It can also act on the connecting rod and slide block mechanism, make slide block reciprocates in the box slipway, plunger is also driven to do reciprocating movement. When the plunger is retracted, vacuum is fashioned in hydraulic chamber. At this time, drinking water self-cleansing tank enters the hydraulic chamber through fluid versatile hose, dispensing tube and prime open up suction valve. When the plunger is transferring forward, suction valve closes off. The water is pressurized, the drain valve is opened, and currently being output outward by means of higher force fluid assortment block.
Tank components: Tank is the bearing body of pump, which is manufactured of solid iron with higher strength. One particular of its sides is established with gear box. A pair of gears within the box is produced of high good quality structural alloy steel, with challenging-tooth-floor of higher precision soon after grinding and particular warmth treatment method. It has the functions of sleek rotation, low sounds and excellent use resistance. The crankshaft is created of alloy steel, and crank surface area hardness with large strength can be attained right after particular warmth treatment. Connecting rod big conclude is lined with substantial tin aluminum bearing bush, with excellent put on resistance. Connecting rod large conclude moves in the crankcase.
Pump head assembly: Specifics of pump head assembly remember to see the diagram. Three separated cylinder liners have replaced the traditional block pump heads and a few substantial-strain metal sleeves. This kind of composition can essentially solve the simply-harm connection amongst primary structural pump head and substantial stress metal jacket, which may possibly trigger pump head cracking if not repaired. A few separated heads have significantly simplified the maintenance disassembly, and decreased labor depth. Piston alloy surface area is taken care of with special alloy, in get to enhance the main hardness, wear resistance and corrosion resistance. Plunger and slider are connected by force block, semi-toroidal, nut and locking screw. In the course of the use procedure, changes in the axial gap and screw unfastened should be compensated attention to. Plunger is sealed with imported packing rectangular ring, with lengthier seal daily life. None cross-gap assembly composition (see diagram) is employed on the mix valve, which can realize flexible startup, reliable sealing, and tough existence.
3.2 Aid valve
Purpose:
Aid valve is an important factor of the hydraulic technique, whose position is to guarantee the operation of doing work pipeline under preset pressure. The complete flow of the pump is automatically divided into two areas when passing through the reduction valve, a single is utilised by drinking water gun or a assortment of equipment the extreme stream shall return to the tank, and preserve a continual strain.
Composition and procedure principle:
Pilot operated compound-reduction valve is utilised. It composed of pilot valve and main valve.
Pilot valve component is linked with the back again liquid chamber of main valve through the centre hole, also connects to P port in strain chamber by means of two choke plug holes within the main valve component chamber. In this way, pipeline pressure adjustments of working pipeline can reflect to the pilot valve factor. When adjusting the pilot valve spring, force amongst choke plug and pilot valve will improve, resulting in pressure in the doing work chamber. Adjust the working stress repeatedly till appropriate and steady operating strain is received. Beneath the circumstance there is no stress among choke plug and pilot valve, the doing work strain shall be zero.
three.3 Basic safety valve
The part of safety valve is to conduct overload defense on pump station, i.e. the force relief can be began routinely when the pump force is increased owing to sudden factors.
Framework is shown in the diagram. 1 end of the valve is related with high stress chamber, when the stress exceeds a predetermined value, hydraulic pressure shall struggle towards the spring pressure to open the valve and release force. CZPTly, the stress of secure valve shall be adjusted to 110% of the doing work stress. The nut is fixed after the adjustment to prevent loosening.
No matter think about from the protected procedure of pump station, or from the basic safety issues of personnel, the established up of secure valve should be taken into account.
