The functioning basic principle of the three-blade roots blower: two three-lobed rotors are organized 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 reverse 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.
Function of our roots blower:
1. Massive adjustment of the air volume
2. Low Sounds
3. Higher performance
4. Low vitality cosumption
five. Lengthy time existence
six. Trustworthy operating, simple servicing,small footprint

absorb and increase the domestic innovative creation technologies, so as to market the upgrading and
optimization of the item and make the solution quality attain the superior stage at property and overseas.
ESR -type Roots Blower contains a number of collection these kinds of as 3-leaves Kind, Two-leaves Sort and Centrifugal
Kind,which can be more divided to hundreds of types. The products are widely utilized in sewage treatment method,
pneumatic conveying,vacuum packaging, aquaculture, food processing, electrical energy, petrochemical, cement,
mining and other industries. Our items have such positive aspects as lower noise, energy conserving, steady good quality,
and lengthy support life, and so forth.. With the revenue outlets throughout the domestic cash metropolitan areas, our merchandise sell well all
more than the region, and have been exported to North CZPTica,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other nations. Having got the ISO9001 CZPT CZPT System Certification, we have
set up and enhanced the high quality assurance of the goods designing, producing, and set up.
From the procedure of design, research and improvement to the finished items, we have got the whole
process controlled independently, hence supplying the complete foundation and trustworthiness guarantee for the goods balance
and durability. Possessing a perfect revenue network and soon after-product sales support, we provide our consumers with larger-
quality and a lot more productive service.All employees of our business sincerely welcome the wide masses of buddies to
information, and negotiate company with us.

The Application of the Roots Blower
Upkeep and inspection
(1) Check out all fasteners and locating pins circumstances no matter whether they are loosening.
(2) Always check whether or not the leakage phenomenon of the physique.
(three) Pay focus to lubrication, amount of grease and noises when running,
determine whether it functions under the needed circumstances.
(four) 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 after initial 200 hrs working, and exchange
once more right after a moth working. Later on, substitute the lubricant and grease in accordance to the
surroundings and lubricant (grease) good quality suggest a ideal alternative for a few
months.
(5) Usually check out the inlet air filter, cleanse or change the filter in time.
(6) Blower overload often not right away exhibited, so pay out attention to
the consumption and exhaust stress, bearing temperature and the recent boost traits
of motor to establish no matter whether the blower performs normally
(7) Ahead of disassembling the blower, the assembling relation and proportions
have to be recorded or calculated, make marks on elements to make sure the CZPT
needs right after assembling.
(8) When newly machine or overhaul, the oil tank need to be cleaned just before use
and suggest exchange all grease right after 8 hrs running.
Frequent failure purpose and troubleshooting
No | Failure | Possible factors | Elimination methods |
one | Friction amongst the impeller |
(1) Impurities on the impeller, ensuing in the hole is too modest (2) Equipment put on, ensuing in a large backlash (3) The equipment is not effectively fixed, can not preserve the impeller synchronization (four) Bearing use ensuing in clearance increasing. |
(one) Eliminate grime and verify whether or not there is hurt components (2) Alter the gear gap, replace the gears if the equipment backlash is better than the regular 30% to 50% (3)Re-assemble the gears, hold the taper contact area is to seventy five% (four)Change the bearing |
two | Collision among impeller and wall, the impeller prime and casing |
(1) Installation hole is not correct (2) working force is as well large, exceeding the specified benefit (3) Operating temperature is way too large (four) Casing or base deformation, positioning admirer failure (5) Bearing axial place is not very good |
(one) Adjust the gap (2) Determine triggers of overloading, lowered the strain to the specified benefit (3) Examine the installation accuracy and decrease the pipe rigidity (four) Check out and mend bearings, and to make sure the clearance (5)Relocation |
3 | Temperature also higher |
(1) Oil in tank is also considerably, way too thick or too filthy (two) CZPT or silencer is blocked (3)The pressure is higher than the specified benefit (four)Excessive put on of the impeller, large hole (five)Very poor ventilation, indoor temperature is large, ensuing in inlet air’s large temperature (6) The rotating speed is also low,outcome in the belt slipping. |
(one)Lessen the oil degree or count on oil (two)Remove of blocking objects (3)Minimizing the pressure by means of the blower (4)Repair its clearance (five)Open vents to reduce area temperature (six) Enhance velocity to avoid the belt slipping. |
four | Insufficient circulation |
(one) The inlet filter is blocked (two) Impeller use and the gap increases as well a lot (3) Belt slipping (4) Big imports force loss (5) CZPT ventilation leakage |
(one) Clean the filter dust and obstruction (two) Mend the hole (three)Tighten the belt and enhance the quantity of belts (4)Change the inlet strain to the specified value (5) Verify and mend the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(one)Substantial tank position lead to leakage from the discharge port (two) Seal dress in, ensuing in shaft oil spills (3) The pressure is increased than the specified benefit |
(one)Reduce the oil level (2)Change the seals (3)Distinct the air vents, 2mm diameter faucet is fixed in the center chamber, open up the faucet underneath the wall |
6 | Abnormal vibration and sounds |
(one)Bearing clearance exceeds the specified value or bearing use (two) The gear backlash is too huge, not in a limited fixed (3) The international objects and dust caused by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation caused the collision triggered by overload, (five) Friction between the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller brought on by fouling or overseas body (7) CZPT bolts or other fasteners are loosened |
(one)Exchange bearings or bearing seat (two)Reassemble gear and ensure backlash (3)Cleansing blower, verify the circumstance is ruined (4)Examine the back again pressure, examine the wheel and change hole (5)Examine the filter and again stress, increase the hole in between the impeller inlet and the casing (six)Clean the impeller and the casing, to make certain that the impeller clearance operate (seven) Tighten the anchor bolts and leveling the foundation. |
seven | Motor overload |
(1)Compared with the necessary stress, the strain distinction is large that the again pressure or the inlet stress is high (two) Compared with the tools needs, blower flow is also large, so its stress boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating parts (five) The oil stage is too high (six) Narrow V-belt is overheat, vibration is also huge, or pulley is way too tiny |
(1) Minimize the stress to the specified price (2) Exhaust the excessive gas into the environment or lessen the blower velocity (three) Eliminate the obstructions (four)Right away shut down, examine the purpose (five) Change the oil to the correct degree (six) Check out the belt stress, and replaced it with huge diameter pulley. |
