The doing work basic 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 both sides of the cavity. Via the motion of a pair of
synchronous gears, the two rotors rotate in reverse directions 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 attain the
purpose of blowing.
Feature of our roots blower:
1. Huge adjustment of the air volume
2. Reduced Noise
three. Large performance
4. Minimal power cosumption
five. Long time daily life
6. Dependable managing, simple upkeep,little footprint

Doosn Horzitonal CZPT Heart
The Application of the Roots Blower
Servicing and inspection
(one) Check out all fasteners and locating pins situations no matter whether they are loosening.
(two) Often examine no matter whether the leakage phenomenon of the body.
(three) Pay focus to lubrication, sum of grease and noises when managing,
figure out whether or not it performs beneath the required problems.
(4) CZPT & grease: The lubricant is for medium load industrial gear 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). Change the lubricant and grease right after first two hundred hrs managing, and replace
again following a moth working. Later on, substitute the lubricant and grease in accordance to the
atmosphere and lubricant (grease) good quality propose a appropriate substitution for three
months.
(five) Often examine the inlet air filter, cleanse or substitute the filter in time.
(6) Blower overload occasionally not immediately exhibited, so spend attention to
the ingestion and exhaust pressure, bearing temperature and the present boost tendencies
of motor to decide whether the blower functions normally
(seven) Prior to disassembling the blower, the assembling relation and proportions
should be recorded or calculated, make marks on factors to ensure the CZPT
requirements right after assembling.
(8) When freshly equipment or overhaul, the oil tank must be cleaned ahead of use
and suggest replace all grease following eight hours managing.
Widespread failure cause and troubleshooting
No | Failure | Possible factors | Elimination techniques |
1 | Friction between the impeller |
(one) Impurities on the impeller, resulting in the gap is as well little (two) Gear dress in, ensuing in a big backlash (three) The equipment is not well set, can not maintain the impeller synchronization (4) Bearing dress in ensuing in clearance increasing. |
(one) Get rid of filth and examine no matter whether there is hurt components (two) Modify the equipment gap, substitute the gears if the gear backlash is higher than the average 30% to fifty% (three)Re-assemble the gears, hold the taper make contact with region is to seventy five% (four)Replace the bearing |
2 | Collision among impeller and wall, the impeller top and casing |
(one) Set up hole is not correct (2) functioning pressure is too large, exceeding the specified price (three) Functioning temperature is also high (4) Casing or base deformation, positioning admirer failure (five) Bearing axial place is not great |
(1) Adjust the gap (two) Recognize brings about of overloading, lowered the force to the specified benefit (3) Verify the installation accuracy and reduce the pipe stress (four) Examine and fix bearings, and to ensure the clearance (5)Relocation |
three | Temperature way too higher |
(1) Oil in tank is as well a lot, too thick or too dirty (2) CZPT or silencer is blocked (three)The strain is increased than the specified value (4)Extreme put on of the impeller, huge hole (5)Bad ventilation, indoor temperature is substantial, resulting in inlet air’s high temperature (six) The rotating pace is as well lower,end result in the belt slipping. |
(1)Decrease the oil level or count on oil (two)Get rid of of blocking objects (3)Reducing the force through the blower (four)Fix its clearance (five)Open vents to decrease space temperature (six) Increase speed to avoid the belt slipping. |
4 | Insufficient movement |
(one) The inlet filter is blocked (2) Impeller put on and the hole boosts as well significantly (three) Belt slipping (four) Massive imports pressure loss (5) CZPT air flow leakage |
(1) Thoroughly clean the filter dust and obstruction (two) Fix the hole (three)Tighten the belt and improve the quantity of belts (4)Alter the inlet strain to the specified benefit (5) Check out and repair the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(1)Substantial tank position trigger leakage from the discharge port (2) Seal wear, resulting in shaft oil spills (3) The force is larger than the specified worth |
(1)Minimize the oil degree (two)Change the seals (3)Obvious the air vents, 2mm diameter faucet is fastened in the middle chamber, open up the faucet under the wall |
6 | Irregular vibration and sounds |
(one)Bearing clearance exceeds the specified worth or bearing put on (two) The equipment backlash is also large, not in a limited fastened (three) The foreign objects and dust induced by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation triggered the collision triggered by overload, (five) Friction among the impeller and the inlet housing induced by overheating (six) Unbalance of the impeller brought on by fouling or international human body (seven) CZPT bolts or other fasteners are loosened |
(one)Exchange bearings or bearing seat (2)Reassemble equipment and guarantee backlash (three)Cleaning blower, verify the scenario is broken (4)Check out the again strain, check the wheel and alter gap (5)Check out the filter and back again stress, enhance the hole in between the impeller inlet and the casing (6)Clean the impeller and the casing, to make sure that the impeller clearance perform (seven) Tighten the anchor bolts and leveling the foundation. |
seven | Motor overload |
(one)In comparison with the required pressure, the force difference is massive that the again pressure or the inlet pressure is substantial (2) In comparison with the tools demands, blower movement is also big, so its strain boosts (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (stuck) rotating areas (five) The oil stage is also substantial (six) Narrow V-belt is overheat, vibration is as well massive, or pulley is as well tiny |
(1) Lessen the strain to the specified value (two) Exhaust the excess gas into the atmosphere or lessen the blower velocity (three) Get rid of the obstructions (four)Quickly shut down, check out the reason (five) Modify the oil to the right degree (six) Check the belt tension, and changed it with huge diameter pulley. |
