The working principle of the three-blade roots blower: two 3-lobed rotors are arranged 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 opposite 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 attain the
objective of blowing.
Function of our roots blower:

with numerous scientific research units, faculties and universities at property and abroad. We also continuously try to
take in and improve the domestic innovative production systems, so as to market the upgrading and
optimization of the solution and make the merchandise good quality attain the superior stage at home and abroad.
ESR -type Roots Blower includes numerous series such as A few-leaves Type, Two-leaves Kind and Centrifugal
Sort,which can be further divided to hundreds of varieties. The goods are widely utilised in sewage treatment method,
pneumatic conveying,vacuum packaging, aquaculture, foods processing, electric electricity, petrochemical, cement,
mining and other industries. Our items have such benefits as minimal sound, power conserving, steady high quality,
and prolonged service life, and many others.. With the income outlets throughout the domestic capital cities, our merchandise offer effectively all
above the country, and have been exported to North CZPTica,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other countries. Having acquired the ISO9001 CZPT CZPT System Certification, we have
set up and enhanced the good quality assurance of the items developing, manufacturing, and set up.
From the process of design and style, research and advancement to the concluded goods, we have acquired the whole
approach controlled independently, as a result offering the complete basis and reliability promise for the products balance
and toughness. Obtaining a perfect revenue network and soon after-product sales provider, we offer our consumers with higher-
high quality and a lot more productive provider.All workers of our firm sincerely welcome the broad masses of pals to
manual, and negotiate business with us.

The Software of the Roots Blower
Routine maintenance and inspection
(1) Check all fasteners and locating pins situations no matter whether they are loosening.
(two) Usually check out whether the leakage phenomenon of the human body.
(three) Pay interest to lubrication, sum of grease and noises when managing,
determine no matter whether it works beneath the essential situations.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop point ≥
190ºC). Replace the lubricant and grease right after very first two hundred hrs working, and exchange
again right after a moth working. Afterwards, change the lubricant and grease according to the
surroundings and lubricant (grease) high quality propose a ideal substitution for three
months.
(five) Usually check the inlet air filter, clean or exchange the filter in time.
(six) Blower overload occasionally not instantly shown, so pay out attention to
the intake and exhaust strain, bearing temperature and the existing increase tendencies
of motor to establish whether or not the blower operates usually
(7) Prior to disassembling the blower, the assembling relation and proportions
need to be recorded or calculated, make marks on parts to make certain the CZPT
needs right after assembling.
(8) When recently equipment or overhaul, the oil tank should be cleaned before use
and suggest substitute all grease following eight several hours managing.
Widespread failure explanation and troubleshooting
No | Failure | Possible motives | Elimination methods |
one | Friction among the impeller |
(one) Impurities on the impeller, ensuing in the hole is too modest (two) Gear use, resulting in a massive backlash (3) The equipment is not effectively fastened, can not keep the impeller synchronization (4) Bearing put on ensuing in clearance growing. |
(one) Get rid of dust and check whether or not there is damage components (two) Alter the equipment hole, replace the gears if the gear backlash is higher than the average thirty% to 50% (three)Re-assemble the gears, maintain the taper get in touch with spot is to seventy five% (4)Change the bearing |
two | Collision between impeller and wall, the impeller prime and casing |
(1) Set up hole is not appropriate (two) working pressure is way too high, exceeding the specified value (three) Operating temperature is as well high (4) Casing or base deformation, positioning supporter failure (five) Bearing axial area is not excellent |
(1) Alter the hole (2) Discover leads to of overloading, decreased the strain to the specified price (three) Check out the set up accuracy and minimize the pipe pressure (4) Check and mend bearings, and to make certain the clearance (5)Relocation |
three | Temperature way too large |
(1) Oil in tank is way too significantly, way too thick or too soiled (two) CZPT or silencer is blocked (3)The pressure is higher than the specified value (four)Extreme put on of the impeller, large hole (5)Inadequate air flow, indoor temperature is substantial, resulting in inlet air’s high temperature (six) The rotating pace is too reduced,end result in the belt slipping. |
(one)Lessen the oil degree or count on oil (2)Take away of blocking objects (3)Lowering the strain via the blower (four)Mend its clearance (5)Open vents to lessen room temperature (6) Boost pace to avert the belt slipping. |
four | Inadequate flow |
(one) The inlet filter is blocked (2) Impeller use and the gap will increase as well considerably (three) Belt slipping (four) Big imports pressure loss (5) CZPT air flow leakage |
(1) Thoroughly clean the filter dust and obstruction (2) Restore the hole (3)Tighten the belt and increase the amount of belts (four)Adjust the inlet pressure to the specified value (5) Check and restore the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(one)Higher tank position trigger leakage from the discharge port (two) Seal dress in, ensuing in shaft oil spills (three) The strain is larger than the specified value |
(one)Reduce the oil amount (2)Exchange the seals (three)Distinct the air vents, 2mm diameter faucet is set in the middle chamber, open the faucet under the wall |
six | Abnormal vibration and noise |
(one)Bearing clearance exceeds the specified price or bearing dress in (two) The equipment backlash is way too big, not in a tight set (3) The international objects and dust induced by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation induced the collision induced by overload, (5) Friction in between the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller caused by fouling or overseas physique (seven) CZPT bolts or other fasteners are loosened |
(one)Exchange bearings or bearing seat (two)Reassemble equipment and ensure backlash (three)Cleansing blower, verify the case is broken (four)Examine the again force, check out the wheel and change hole (5)Check out the filter and back pressure, 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 function (seven) Tighten the anchor bolts and leveling the base. |
7 | Motor overload |
(one)When compared with the essential pressure, the strain distinction is huge that the again strain or the inlet strain is higher (2) In comparison with the equipment needs, blower flow is way too large, so its force raises (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating parts (5) The oil stage is also higher (six) Slender V-belt is overheat, vibration is as well big, or pulley is way too little |
(1) Lessen the pressure to the specified price (two) Exhaust the extra fuel into the atmosphere or lessen the blower pace (3) Eliminate the obstructions (four)Quickly shut down, check the reason (five) Change the oil to the right stage (six) Check the belt stress, and changed it with massive diameter pulley. |
