The working principle of the three-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. Via the action of a pair of
synchronous gears, the two rotors rotate in reverse instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gasoline in the chamber is pushed to attain the
purpose of blowing.
Characteristic of our roots blower:
one. Large adjustment of the air volume
2. Lower Sounds
3. Higher efficiency
four. Lower energy cosumption
5. Extended time lifestyle
six. Reputable operating, effortless servicing,small footprint

The Software of the Roots Blower
Servicing and inspection
(one) Verify all fasteners and finding pins conditions whether or not they are loosening.
(2) Often examine no matter whether the leakage phenomenon of the physique.
(3) Pay focus to lubrication, sum of grease and noises when operating,
determine whether or not it works underneath the required problems.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall stage ≥
190ºC). Change the lubricant and grease following 1st two hundred hrs operating, and substitute
yet again following a moth managing. Later on, replace the lubricant and grease according to the
atmosphere and lubricant (grease) top quality suggest a suited substitution for three
months.
(five) Always check the inlet air filter, clear or replace the filter in time.
(6) Blower overload often not instantly exhibited, so pay out interest to
the consumption and exhaust stress, bearing temperature and the recent increase developments
of motor to decide regardless of whether the blower works typically
(7) Ahead of disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on parts to guarantee the CZPT
specifications right after assembling.
(8) When freshly machine or overhaul, the oil tank should be cleaned before use
and propose exchange all grease following eight hrs working.
Widespread failure purpose and troubleshooting
No | Failure | Possible factors | Elimination methods |
1 | Friction amongst the impeller |
(one) Impurities on the impeller, ensuing in the hole is way too modest (two) Gear wear, ensuing in a massive backlash (3) The equipment is not nicely fastened, can not sustain the impeller synchronization (4) Bearing use resulting in clearance escalating. |
(one) Remove grime and examine whether there is injury components (two) Change the equipment gap, replace the gears if the equipment backlash is higher than the regular thirty% to 50% (three)Re-assemble the gears, hold the taper speak to area is to 75% (4)Substitute the bearing |
2 | Collision among impeller and wall, the impeller top and casing |
(one) Set up gap is not correct (two) operating force is as well higher, exceeding the specified worth (3) Functioning temperature is way too higher (4) Casing or foundation deformation, positioning admirer failure (5) Bearing axial area is not good |
(1) Modify the gap (2) Determine triggers of overloading, diminished the stress to the specified price (3) Check out the set up accuracy and minimize the pipe pressure (4) Check and fix bearings, and to make certain the clearance (five)Relocation |
three | Temperature as well high |
(1) Oil in tank is way too a lot, also thick or also filthy (2) CZPT or silencer is blocked (3)The stress is higher than the specified worth (four)Extreme put on of the impeller, large gap (five)Very poor ventilation, indoor temperature is substantial, resulting in inlet air’s higher temperature (6) The rotating velocity is also low,result in the belt slipping. |
(one)Decrease the oil degree or depend on oil (2)Eliminate of blocking objects (3)Decreasing the pressure via the blower (four)Restore its clearance (5)Open up vents to lessen space temperature (six) Enhance velocity to avoid the belt slipping. |
4 | Inadequate flow |
(one) The inlet filter is blocked (2) Impeller dress in and the hole raises as well significantly (3) Belt slipping (4) Massive imports pressure loss (five) CZPT ventilation leakage |
(one) Clear the filter dust and obstruction (two) Repair the gap (3)Tighten the belt and increase the variety of belts (4)Change the inlet stress to the specified value (5) Verify and mend the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(one)Substantial tank situation cause leakage from the discharge port (two) Seal wear, resulting in shaft oil spills (three) The pressure is higher than the specified value |
(one)Lessen the oil level (2)Replace the seals (3)Very clear the air vents, 2mm diameter faucet is fastened in the middle chamber, open up the faucet under the wall |
6 | Irregular vibration and sounds |
(1)Bearing clearance exceeds the specified price or bearing dress in (two) The gear backlash is too massive, not in a limited mounted (3) The overseas objects and dust induced by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation brought on the collision brought on by overload, (five) Friction in between the impeller and the inlet housing brought on by overheating (6) Unbalance of the impeller brought on by fouling or foreign entire body (7) CZPT bolts or other fasteners are loosened |
(one)Substitute bearings or bearing seat (2)Reassemble gear and make sure backlash (three)Cleansing blower, verify the scenario is damaged (four)Examine the again pressure, verify the wheel and change gap (5)Check out the filter and back again force, increase the hole among the impeller inlet and the casing (6)Clear the impeller and the casing, to make certain that the impeller clearance operate (7) Tighten the anchor bolts and leveling the base. |
7 | Motor overload |
(one)Compared with the essential strain, the pressure difference is large that the back pressure or the inlet force is substantial (two) When compared with the equipment specifications, blower movement is too large, so its stress increases (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating elements (5) The oil amount is as well higher (6) Narrow V-belt is overheat, vibration is too big, or pulley is also modest |
(1) Decrease the pressure to the specified value (2) Exhaust the extra gas into the atmosphere or decrease the blower speed (three) Get rid of the obstructions (four)Right away shut down, examine the reason (five) Change the oil to the appropriate degree (six) Check the belt tension, and changed it with huge diameter pulley. |
