The operating principle of the a few-blade roots blower: two 3-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. By way of 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 gas in the chamber is pushed to obtain the
objective of blowing.
Characteristic of our roots blower:
one. Huge adjustment of the air volume
two. Reduced Sound
three. Higher performance
4. Minimal energy cosumption
5. Prolonged time lifestyle
6. Reputable working, easy routine maintenance,small footprint

The Application of the Roots Blower
Routine maintenance and inspection
(one) Check all fasteners and locating pins circumstances whether they are loosening.
(2) Constantly examine regardless of whether the leakage phenomenon of the human body.
(three) Pay out attention to lubrication, sum of grease and noises when working,
decide whether or not it functions below the needed situations.
(four) 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 (artificial lithium grease penetration 220-250, fall stage ≥
190ºC). Replace the lubricant and grease right after 1st 200 several hours running, and replace
once more soon after a moth operating. Later, change the lubricant and grease according to the
surroundings and lubricant (grease) high quality suggest a suitable substitute for three
months.
(five) Constantly check the inlet air filter, thoroughly clean or replace the filter in time.
(six) Blower overload occasionally not instantly exhibited, so pay attention to
the consumption and exhaust stress, bearing temperature and the current boost trends
of motor to establish regardless of whether the blower operates typically
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
need to be recorded or measured, make marks on components to make sure the CZPT
requirements following assembling.
(8) When newly device or overhaul, the oil tank must be cleaned ahead of use
and propose change all grease soon after eight several hours managing.
Widespread failure explanation and troubleshooting
No | Failure | Feasible factors | Elimination strategies |
1 | Friction between the impeller |
(1) Impurities on the impeller, ensuing in the hole is too modest (two) Gear dress in, resulting in a huge backlash (three) The gear is not properly fixed, can not maintain the impeller synchronization (four) Bearing dress in resulting in clearance growing. |
(one) Remove dirt and examine whether there is hurt parts (2) Modify the gear hole, replace the gears if the equipment backlash is better than the regular 30% to fifty% (3)Re-assemble the gears, keep the taper speak to location is to seventy five% (4)Substitute the bearing |
two | Collision among impeller and wall, the impeller prime and casing |
(one) Set up hole is not proper (two) working strain is way too higher, exceeding the specified benefit (three) Operating temperature is way too high (4) Casing or base deformation, positioning admirer failure (five) Bearing axial location is not excellent |
(one) Modify the gap (two) Determine leads to of overloading, lowered the stress to the specified benefit (3) Check out the set up precision and reduce the pipe tension (four) Check and repair bearings, and to make certain the clearance (five)Relocation |
три | Temperature too substantial |
(one) Oil in tank is way too a lot, as well thick or also filthy (2) CZPT or silencer is blocked (3)The strain is increased than the specified worth (four)Abnormal wear of the impeller, huge hole (five)Poor air flow, indoor temperature is high, resulting in inlet air’s high temperature (six) The rotating velocity is as well low,consequence in the belt slipping. |
(one)Decrease the oil degree or depend on oil (two)Get rid of of blocking objects (three)Lowering the strain via the blower (four)Restore its clearance (5)Open up vents to minimize place temperature (6) Improve speed to stop the belt slipping. |
four | Inadequate movement |
(1) The inlet filter is blocked (2) Impeller put on and the gap will increase also a lot (three) Belt slipping (four) Huge imports pressure loss (five) CZPT ventilation leakage |
(1) Clear the filter dust and obstruction (two) Fix the gap (three)Tighten the belt and boost the variety of belts (4)Alter the inlet force to the specified value (five) Examine and fix the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(1)High tank placement lead to leakage from the discharge port (two) Seal dress in, resulting in shaft oil spills (three) The stress is increased than the specified price |
(one)Reduce the oil stage (two)Substitute the seals (3)Obvious the air vents, 2mm diameter faucet is set in the center chamber, open up the faucet below the wall |
six | Abnormal vibration and noise |
(one)Bearing clearance exceeds the specified worth or bearing use (two) The gear backlash is way too large, not in a limited mounted (three) The foreign objects and dust brought on by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation triggered the collision induced by overload, (five) Friction amongst the impeller and the inlet housing brought on by overheating (six) Unbalance of the impeller caused by fouling or foreign human body (7) CZPT bolts or other fasteners are loosened |
(1)Exchange bearings or bearing seat (two)Reassemble gear and ensure backlash (three)Cleansing blower, examine the circumstance is damaged (four)Verify the again pressure, check out the wheel and change hole (5)Check the filter and back again force, increase the gap in between the impeller inlet and the casing (six)Thoroughly clean the impeller and the casing, to make certain that the impeller clearance function (7) Tighten the anchor bolts and leveling the base. |
7 | Двигатель overload |
(one)In comparison with the essential stress, the pressure difference is massive that the again stress or the inlet pressure is high (2) Compared with the tools demands, blower circulation is way too big, so its force raises (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (trapped) rotating elements (five) The oil degree is also high (6) Slim V-belt is overheat, vibration is too huge, or pulley is way too small |
(1) Reduce the strain to the specified worth (two) Exhaust the surplus gas into the atmosphere or minimize the blower velocity (3) Eliminate the obstructions (four)Immediately shut down, check the explanation (5) Alter the oil to the proper degree (6) Check the belt tension, and replaced it with big diameter pulley. |
