The working principle of the 3-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. By way of the motion 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 fuel in the chamber is pushed to achieve the
function of blowing.
Attribute of our roots blower:
1. Huge adjustment of the air volume
2. Minimal Noise
3. Large effectiveness
four. Minimal power cosumption
5. Prolonged time daily life
six. Trustworthy running, straightforward upkeep,little footprint

Servicing and inspection
(1) Check all fasteners and locating pins problems no matter whether they are loosening.
(two) Constantly examine no matter whether the leakage phenomenon of the body.
(3) Pay focus to lubrication, volume of grease and noises when operating,
determine regardless of whether it functions beneath the necessary conditions.
(four) 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 (artificial lithium grease penetration 220-250, fall stage ≥
190ºC). Replace the lubricant and grease right after first two hundred hours operating, and exchange
once more soon after a moth running. Later, replace the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality propose a suited substitute for a few
months.
(five) Usually check out the inlet air filter, cleanse or exchange the filter in time.
(six) Blower overload at times not quickly shown, so shell out interest to
the ingestion and exhaust force, bearing temperature and the present enhance trends
of motor to figure out whether or not the blower works generally
(seven) Just before disassembling the blower, the assembling relation and proportions
must be recorded or measured, make marks on elements to make certain the CZPT
requirements right after assembling.
(8) When freshly equipment or overhaul, the oil tank must be cleaned before use
and propose replace all grease after eight hours operating.
Widespread failure explanation and troubleshooting
No | Failure | Feasible reasons | Elimination strategies |
1 | Friction amongst the impeller |
(1) Impurities on the impeller, resulting in the gap is also small (2) Equipment dress in, ensuing in a big backlash (3) The gear is not effectively fastened, can not sustain the impeller synchronization (four) Bearing wear resulting in clearance rising. |
(one) Remove filth and check out regardless of whether there is injury elements (2) Change the equipment gap, substitute the gears if the gear backlash is increased than the regular 30% to 50% (3)Re-assemble the gears, maintain the taper make contact with spot is to seventy five% (four)Exchange the bearing |
2 | Collision in between impeller and wall, the impeller leading and casing |
(1) Installation hole is not correct (2) working pressure is also substantial, exceeding the specified value (3) Running temperature is also high (four) Casing or foundation deformation, positioning fan failure (5) Bearing axial area is not very good |
(one) Adjust the hole (2) Discover triggers of overloading, decreased the pressure to the specified benefit (3) Verify the set up accuracy and minimize the pipe tension (four) Verify and restore bearings, and to make certain the clearance (five)Relocation |
3 | Temperature way too substantial |
(1) Oil in tank is also a lot, way too thick or too soiled (two) CZPT or silencer is blocked (3)The strain is larger than the specified benefit (four)Too much wear of the impeller, big hole (five)Inadequate air flow, indoor temperature is substantial, ensuing in inlet air’s large temperature (six) The rotating speed is too minimal,result in the belt slipping. |
(one)Lessen the oil stage or count on oil (2)Eliminate of blocking objects (three)Reducing the pressure via the blower (4)Repair its clearance (5)Open up vents to decrease room temperature (six) Increase speed to avert the belt slipping. |
4 | Insufficient flow |
(1) The inlet filter is blocked (2) Impeller wear and the gap will increase way too a lot (three) Belt slipping (four) Massive imports pressure decline (5) CZPT air flow leakage |
(1) Clean the filter dust and obstruction (two) Restore the gap (three)Tighten the belt and enhance the variety of belts (4)Modify the inlet stress to the specified price (5) Verify and restore the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(one)Substantial tank position result in leakage from the discharge port (2) Seal dress in, resulting in shaft oil spills (three) The pressure is larger than the specified benefit |
(1)Lessen the oil stage (2)Change the seals (three)Clear the air vents, 2mm diameter faucet is fixed in the middle chamber, open the faucet underneath the wall |
six | Abnormal vibration and sounds |
(one)Bearing clearance exceeds the specified worth or bearing put on (2) The equipment backlash is way too large, not in a limited fastened (three) The foreign objects and dust triggered by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation brought on the collision brought on by overload, (five) Friction amongst the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller caused by fouling or foreign human body (seven) CZPT bolts or other fasteners are loosened |
(one)Change bearings or bearing seat (2)Reassemble equipment and ensure backlash (3)Cleaning blower, check the case is ruined (four)Check the back stress, check the wheel and change hole (5)Examine the filter and back again pressure, increase the hole amongst the impeller inlet and the casing (6)Clean the impeller and the casing, to guarantee that the impeller clearance work (seven) Tighten the anchor bolts and leveling the foundation. |
seven | Motor overload |
(one)In contrast with the essential force, the stress difference is big that the back force or the inlet pressure is high (2) In comparison with the products needs, blower flow is way too massive, so its pressure increases (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating parts (5) The oil stage is as well higher (six) Slim V-belt is overheat, vibration is way too big, or pulley is too modest |
(one) Lessen the strain to the specified benefit (two) Exhaust the extra fuel into the ambiance or minimize the blower speed (3) Take away the obstructions (four)Instantly shut down, check out the explanation (5) Alter the oil to the proper level (6) Examine the belt stress, and replaced it with massive diameter pulley. |
