The working principle of the 3-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both 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 gasoline in the chamber is pushed to obtain the
function of blowing.

with many scientific research units, colleges and universities at home and abroad. We also continually consider to
absorb and increase the domestic innovative manufacturing technologies, so as to market the upgrading and
optimization of the item and make the merchandise top quality get to the advanced degree at home and abroad.
ESR -type Roots Blower contains many series this sort of as A few-leaves Variety, Two-leaves Kind and Centrifugal
Sort,which can be further divided to hundreds of kinds. The products are widely utilised in sewage remedy,
pneumatic conveying,vacuum packaging, aquaculture, foods processing, electric powered energy, petrochemical, cement,
mining and other industries. Our items have such advantages as reduced sounds, strength saving, secure good quality,
and long support lifestyle, and many others.. With the revenue outlets throughout the domestic money metropolitan areas, our products promote well all
over the nation, and have been exported to North CZPTica,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other nations. Possessing got the ISO9001 CZPT CZPT Method Certification, we have
recognized and enhanced the top quality assurance of the products creating, production, and installation.
From the procedure of layout, analysis and advancement to the completed items, we have got the entire
method managed independently, hence providing the complete basis and reliability ensure for the merchandise balance
and sturdiness. Having a perfect income network and after-income services, we provide our consumers with higher-
top quality and more successful provider.All workers of our firm sincerely welcome the wide masses of buddies to
information, and negotiate organization with us.

The Application of the Roots Blower
Maintenance and inspection
(one) Examine all fasteners and locating pins problems regardless of whether they are loosening.
(2) Often verify regardless of whether the leakage phenomenon of the body.
(3) Spend interest to lubrication, quantity of grease and noises when managing,
establish whether or not it functions under the required problems.
(four) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop stage ≥
190ºC). Substitute the lubricant and grease following first two hundred hours operating, and substitute
once again following a moth operating. Afterwards, change the lubricant and grease according to the
surroundings and lubricant (grease) quality suggest a ideal replacement for three
months.
(5) Always examine the inlet air filter, clean or exchange the filter in time.
(6) Blower overload occasionally not immediately exhibited, so pay attention to
the consumption and exhaust force, bearing temperature and the present enhance developments
of motor to figure out whether or not the blower performs generally
(7) Prior to disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on parts to make certain the CZPT
demands after assembling.
(8) When freshly equipment or overhaul, the oil tank should be cleaned just before use
and propose change all grease soon after 8 several hours running.
Frequent failure cause and troubleshooting
No | Failure | Feasible motives | Elimination techniques |
1 | Friction among the impeller |
(1) Impurities on the impeller, resulting in the hole is as well little (two) Gear put on, ensuing in a huge backlash (three) The equipment is not effectively fastened, can not maintain the impeller synchronization (four) Bearing wear resulting in clearance rising. |
(1) Take away grime and check no matter whether there is injury elements (2) Adjust the equipment hole, exchange the gears if the gear backlash is higher than the common thirty% to 50% (three)Re-assemble the gears, preserve the taper make contact with area is to seventy five% (4)Exchange the bearing |
2 | Collision in between impeller and wall, the impeller prime and casing |
(one) Installation gap is not correct (two) operating strain is too higher, exceeding the specified price (3) Operating temperature is as well large (4) Casing or base deformation, positioning fan failure (5) Bearing axial place is not good |
(1) Adjust the gap (2) Recognize brings about of overloading, diminished the stress to the specified benefit (three) Examine the set up accuracy and minimize the pipe stress (4) Check and mend bearings, and to guarantee the clearance (5)Relocation |
three | Temperature too substantial |
(1) Oil in tank is also a lot, too thick or also dirty (two) CZPT or silencer is blocked (three)The strain is higher than the specified worth (four)Excessive wear of the impeller, massive gap (five)Poor ventilation, indoor temperature is higher, ensuing in inlet air’s higher temperature (6) The rotating velocity is also low,end result in the belt slipping. |
(one)Minimize the oil amount or count on oil (two)Remove of blocking objects (3)Reducing the force by way of the blower (four)Mend its clearance (five)Open vents to lessen space temperature (six) Improve pace to avoid the belt slipping. |
4 | Insufficient stream |
(1) The inlet filter is blocked (2) Impeller use and the gap raises too much (three) Belt slipping (four) Big imports stress decline (five) CZPT ventilation leakage |
(one) Clean the filter dust and obstruction (two) Repair the hole (three)Tighten the belt and enhance the variety of belts (4)Adjust the inlet strain to the specified price (5) Check out and restore the pipeline |
5 | Oil leaking or oil leaking into the enclosure |
(1)Higher tank placement cause leakage from the discharge port (two) Seal dress in, resulting in shaft oil spills (3) The stress is greater than the specified price |
(one)Minimize the oil stage (two)Replace the seals (3)Obvious the air vents, 2mm diameter faucet is fixed in the middle chamber, open the faucet beneath the wall |
six | Irregular vibration and sound |
(one)Bearing clearance exceeds the specified worth or bearing dress in (two) The equipment backlash is as well huge, not in a tight fastened (three) The overseas 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 triggered by overload, (5) Friction among the impeller and the inlet housing brought on by overheating (6) Unbalance of the impeller triggered by fouling or overseas body (seven) CZPT bolts or other fasteners are loosened |
(1)Exchange bearings or bearing seat (2)Reassemble equipment and guarantee backlash (three)Cleansing blower, examine the case is damaged (four)Check the back again stress, check out the wheel and change gap (5)Check the filter and back strain, improve the gap amongst the impeller inlet and the casing (6)Thoroughly clean the impeller and the casing, to guarantee that the impeller clearance work (seven) Tighten the anchor bolts and leveling the base. |
7 | Motor overload |
(1)Compared with the needed pressure, the force distinction is massive that the back pressure or the inlet stress is high (two) In comparison with the equipment requirements, blower circulation is too large, so its strain boosts (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (stuck) rotating parts (five) The oil level is as well higher (six) Narrow V-belt is overheat, vibration is also large, or pulley is way too modest |
(1) Reduce the force to the specified worth (two) Exhaust the extra gas into the environment or lessen the blower velocity (three) Remove the obstructions (four)Immediately shut down, check out the explanation (five) Adjust the oil to the appropriate degree (6) Examine the belt pressure, and replaced it with huge diameter pulley. |
