The operating principle of the a few-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. Through the action of a pair of
synchronous gears, the two rotors rotate in opposite 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 achieve the
function of blowing.
Feature of our roots blower:

Servicing and inspection
(1) Check out all fasteners and locating pins conditions whether or not they are loosening.
(2) Always check whether or not the leakage phenomenon of the human body.
(three) Pay out interest to lubrication, sum of grease and noises when managing,
establish whether or not it operates below the necessary circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall position ≥
190ºC). Change the lubricant and grease after 1st two hundred hours managing, and replace
yet again right after a moth working. Afterwards, replace the lubricant and grease in accordance to the
surroundings and lubricant (grease) quality suggest a ideal alternative for a few
months.
(five) Constantly verify the inlet air filter, cleanse or exchange the filter in time.
(6) Blower overload sometimes not quickly exhibited, so pay out consideration to
the intake and exhaust force, bearing temperature and the existing increase developments
of motor to establish whether or not the blower functions typically
(seven) Just before disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on components to make certain the CZPT
needs after assembling.
(8) When freshly equipment or overhaul, the oil tank should be cleaned before use
and propose replace all grease right after 8 hours operating.
Widespread failure reason and troubleshooting
No |
Failure |
Attainable causes |
Elimination approaches |
one |
Friction among the impeller |
(1) Impurities on the impeller, ensuing in the hole is as well tiny (2) Gear dress in, resulting in a big backlash (3) The gear is not nicely mounted, can not preserve the impeller synchronization (four) Bearing dress in resulting in clearance increasing. |
(1) Take away dust and check out no matter whether there is harm parts (2) Change the equipment gap, replace the gears if the equipment backlash is higher than the average 30% to fifty% (3)Re-assemble the gears, keep the taper speak to area is to 75% (four)Replace the bearing |
2 |
Collision between impeller and wall, the impeller best and casing |
(one) Set up hole is not right (2) working stress is also high, exceeding the specified benefit (three) Operating temperature is way too high (four) Casing or base deformation, positioning admirer failure (5) Bearing axial area is not great |
(one) Modify the hole (2) Discover leads to of overloading, lowered the strain to the specified value (three) Verify the installation precision and reduce the pipe tension (4) Verify and repair bearings, and to guarantee the clearance (five)Relocation |
three |
Temperature too large |
(one) Oil in tank is way too a lot, way too thick or too filthy (2) CZPT or silencer is blocked (three)The pressure is larger than the specified benefit (4)Excessive put on of the impeller, huge gap (five)Bad ventilation, indoor temperature is substantial, resulting in inlet air’s high temperature (6) The rotating pace is way too lower,end result in the belt slipping. |
(1)Lessen the oil amount or count on oil (two)Take away of blocking objects (three)Minimizing the strain through the blower (four)Repair its clearance (5)Open up vents to lessen place temperature (6) Boost speed to stop the belt slipping. |
4 |
Insufficient flow |
(one) The inlet filter is blocked (two) Impeller put on and the gap raises way too much (3) Belt slipping (four) Big imports strain loss (five) CZPT ventilation leakage |
(1) Clean the filter dust and obstruction (two) Fix the hole (3)Tighten the belt and improve the variety of belts (4)Alter the inlet force to the specified worth (five) Verify and fix the pipeline |
5 |
Oil leaking or oil leaking into the enclosure |
(one)High tank place result in leakage from the discharge port (2) Seal put on, resulting in shaft oil spills (3) The pressure is higher than the specified benefit |
(1)Minimize the oil degree (two)Substitute the seals (3)Clear the air vents, 2mm diameter faucet is set in the center chamber, open the faucet below the wall |
six |
Abnormal vibration and sound |
(1)Bearing clearance exceeds the specified value or bearing put on (2) The gear backlash is as well huge, not in a limited set (three) The international objects and dust induced by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation caused the collision triggered by overload, (five) Friction amongst the impeller and the inlet housing brought on by overheating (6) Unbalance of the impeller caused by fouling or international physique (7) CZPT bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (2)Reassemble gear and guarantee backlash (three)Cleansing blower, examine the situation is damaged (4)Check the back again force, examine the wheel and modify gap (five)Check the filter and back pressure, boost the gap among the impeller inlet and the casing (six)Thoroughly clean the impeller and the casing, to make sure that the impeller clearance perform (7) Tighten the anchor bolts and leveling the foundation. |
seven |
Motor overload |
(one)In comparison with the needed force, the stress difference is huge that the back stress or the inlet strain is high (2) When compared with the products demands, blower circulation is also huge, so its pressure boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (stuck) rotating components (5) The oil degree is as well high (6) Slender V-belt is overheat, vibration is as well massive, or pulley is way too tiny |
(one) Reduce the force to the specified value (two) Exhaust the extra fuel into the environment or lessen the blower speed (3) Remove the obstructions (four)Immediately shut down, examine the purpose (five) Modify the oil to the right degree (6) Check out the belt stress, and replaced it with large diameter pulley. |
