The operating theory 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 means of the action 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 fuel in the chamber is pushed to accomplish the
function of blowing.
Feature of our roots blower:
one. Massive adjustment of the air quantity
2. Reduced Noise
3. High efficiency
4. Reduced power cosumption
five. Lengthy time existence
six. Reliable working, straightforward maintenance,little footprint

The Software of the Roots Blower
Servicing and inspection
(one) Verify all fasteners and locating pins problems no matter whether they are loosening.
(2) Always examine no matter whether the leakage phenomenon of the body.
(3) Spend interest to lubrication, volume of grease and noises when operating,
establish regardless of whether it operates under the required problems.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop point ≥
190ºC). Replace the lubricant and grease following initial two hundred hrs managing, and substitute
once again soon after a moth operating. Later on, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) high quality propose a suited alternative for three
months.
(five) Constantly check the inlet air filter, thoroughly clean or change the filter in time.
(6) Blower overload often not instantly displayed, so pay focus to
the consumption and exhaust strain, bearing temperature and the recent boost traits
of motor to determine no matter whether the blower performs usually
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
must be recorded or measured, make marks on components to make sure the CZPT
needs soon after assembling.
(eight) When newly equipment or overhaul, the oil tank must be cleaned ahead of use
and suggest substitute all grease after eight hrs operating.
Frequent failure reason and troubleshooting
No | Failure | Feasible motives | Elimination techniques |
1 | Friction in between the impeller |
(one) Impurities on the impeller, resulting in the hole is way too little (two) Equipment put on, resulting in a big backlash (three) The equipment is not effectively fastened, can not sustain the impeller synchronization (4) Bearing wear ensuing in clearance rising. |
(1) Get rid of dirt and check out whether there is harm elements (2) Alter the gear gap, exchange the gears if the gear backlash is higher than the typical 30% to fifty% (three)Re-assemble the gears, keep the taper make contact with location is to seventy five% (4)Substitute the bearing |
2 | Collision amongst impeller and wall, the impeller prime and casing |
(1) Installation hole is not right (2) working strain is too higher, exceeding the specified price (3) Operating temperature is too large (4) Casing or base deformation, positioning fan failure (5) Bearing axial location is not very good |
(one) Alter the hole (2) Discover brings about of overloading, lowered the stress to the specified price (three) Check out the installation accuracy and minimize the pipe tension (four) Examine and restore bearings, and to make sure the clearance (five)Relocation |
three | Temperature too large |
(one) Oil in tank is way too considerably, too thick or also soiled (2) CZPT or silencer is blocked (three)The force is greater than the specified value (four)Excessive wear of the impeller, massive hole (5)Very poor ventilation, indoor temperature is higher, resulting in inlet air’s large temperature (6) The rotating velocity is as well minimal,outcome in the belt slipping. |
(one)Decrease the oil level or depend on oil (2)Remove of blocking objects (three)Decreasing the stress by means of the blower (four)Repair its clearance (five)Open vents to reduce space temperature (six) Increase pace to prevent the belt slipping. |
four | Insufficient stream |
(one) The inlet filter is blocked (two) Impeller use and the hole increases too much (3) Belt slipping (4) Big imports stress loss (5) CZPT air flow leakage |
(one) Clear the filter dust and obstruction (two) Repair the gap (3)Tighten the belt and boost the quantity of belts (4)Modify the inlet stress to the specified value (5) Verify and fix the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(1)Higher tank placement trigger leakage from the discharge port (two) Seal use, resulting in shaft oil spills (3) The pressure is larger than the specified benefit |
(1)Lessen the oil level (two)Change the seals (three)Very clear the air vents, 2mm diameter faucet is mounted in the middle chamber, open up the faucet under the wall |
6 | Irregular vibration and sound |
(1)Bearing clearance exceeds the specified benefit or bearing dress in (2) The gear backlash is too huge, not in a limited set (three) The foreign objects and dust induced by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation caused the collision caused by overload, (five) Friction in between the impeller and the inlet housing triggered by overheating (six) Unbalance of the impeller triggered by fouling or international human body (7) CZPT bolts or other fasteners are loosened |
(one)Substitute bearings or bearing seat (two)Reassemble equipment and make certain backlash (three)Cleaning blower, check out the circumstance is broken (four)Verify the again stress, check the wheel and change hole (five)Examine the filter and again stress, boost the gap between the impeller inlet and the casing (6)Clear the impeller and the casing, to make sure that the impeller clearance work (seven) Tighten the anchor bolts and leveling the base. |
seven | Motor overload |
(one)In contrast with the required stress, the pressure big difference is huge that the back again strain or the inlet stress is substantial (2) Compared with the equipment demands, blower movement is too massive, so its strain raises (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating areas (five) The oil stage is way too high (six) Slim V-belt is overheat, vibration is too huge, or pulley is also modest |
(1) Minimize the force to the specified value (2) Exhaust the extra fuel into the ambiance or minimize the blower pace (3) Remove the obstructions (four)Instantly shut down, check out the cause (5) Change the oil to the proper amount (6) Verify the belt pressure, and changed it with big diameter pulley. |
