The functioning principle of the 3-blade roots blower: two a few-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 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 fuel in the chamber is pushed to accomplish the
purpose of blowing.
Function of our roots blower:
1. Massive adjustment of the air volume
two. Reduced Noise
three. High effectiveness
four. Low strength cosumption
five. Lengthy time lifestyle
6. Reputable running, simple servicing,little footprint

The Software of the Roots Blower
Servicing and inspection
(1) Verify all fasteners and locating pins conditions whether or not they are loosening.
(2) Often examine regardless of whether the leakage phenomenon of the human body.
(three) Shell out interest to lubrication, quantity of grease and noises when working,
figure out whether or not it operates underneath the required circumstances.
(four) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop stage ≥
190ºC). Exchange the lubricant and grease following very first two hundred hours operating, and exchange
again right after a moth running. Later on, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality suggest a ideal alternative for a few
months.
(5) Usually check out the inlet air filter, clear or exchange the filter in time.
(6) Blower overload occasionally not instantly shown, so spend attention to
the consumption and exhaust force, bearing temperature and the current boost developments
of motor to figure out whether the blower operates usually
(seven) Just before disassembling the blower, the assembling relation and proportions
must be recorded or measured, make marks on factors to make certain the CZPT
requirements after assembling.
(8) When newly device or overhaul, the oil tank ought to be cleaned before use
and suggest substitute all grease following 8 several hours running.
Common failure purpose and troubleshooting
No | Failure | Attainable reasons | Elimination techniques |
1 | Friction between the impeller |
(one) Impurities on the impeller, ensuing in the hole is way too modest (2) Equipment put on, resulting in a big backlash (3) The gear is not effectively fastened, can not keep the impeller synchronization (four) Bearing use resulting in clearance rising. |
(1) Remove dust and verify no matter whether there is hurt parts (2) Modify the equipment gap, replace the gears if the gear backlash is better than the common 30% to fifty% (3)Re-assemble the gears, maintain the taper speak to area is to 75% (four)Exchange the bearing |
2 | Collision amongst impeller and wall, the impeller top and casing |
(1) Installation hole is not appropriate (two) operating force is way too higher, exceeding the specified worth (3) Functioning temperature is too high (four) Casing or foundation deformation, positioning admirer failure (5) Bearing axial location is not excellent |
(one) Alter the gap (2) Discover triggers of overloading, reduced the force to the specified benefit (three) Verify the set up precision and lessen the pipe tension (4) Check and repair bearings, and to make certain the clearance (five)Relocation |
three | Temperature way too large |
(1) Oil in tank is also considerably, as well thick or way too filthy (two) CZPT or silencer is blocked (three)The strain is increased than the specified worth (four)Excessive put on of the impeller, big hole (five)Bad air flow, indoor temperature is high, ensuing in inlet air’s high temperature (six) The rotating pace is too low,consequence in the belt slipping. |
(one)Decrease the oil amount or depend on oil (two)Get rid of of blocking objects (3)Decreasing the strain via the blower (4)Restore its clearance (5)Open up vents to lessen place temperature (six) Improve pace to prevent the belt slipping. |
four | Insufficient movement |
(one) The inlet filter is blocked (two) Impeller put on and the hole boosts as well considerably (three) Belt slipping (four) Large imports strain reduction (five) CZPT air flow leakage |
(1) Clear the filter dust and obstruction (2) Fix the hole (3)Tighten the belt and enhance the quantity of belts (four)Adjust the inlet strain to the specified worth (5) Examine and fix the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(1)Large tank position trigger leakage from the discharge port (two) Seal dress in, resulting in shaft oil spills (3) The stress is larger than the specified value |
(one)Reduce the oil degree (two)Replace the seals (3)Distinct the air vents, 2mm diameter faucet is fixed in the center chamber, open the faucet below the wall |
six | Abnormal vibration and sound |
(one)Bearing clearance exceeds the specified worth or bearing use (two) The gear backlash is too huge, not in a restricted fixed (three) The international objects and dust triggered by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation caused the collision caused by overload, (five) Friction among the impeller and the inlet housing caused by overheating (six) Unbalance of the impeller brought on by fouling or international physique (7) CZPT bolts or other fasteners are loosened |
(1)Change bearings or bearing seat (2)Reassemble gear and make sure backlash (three)Cleansing blower, examine the scenario is destroyed (four)Examine the again force, verify the wheel and alter hole (five)Verify the filter and back again pressure, improve the gap amongst the impeller inlet and the casing (6)Cleanse the impeller and the casing, to ensure that the impeller clearance work (7) Tighten the anchor bolts and leveling the base. |
7 | Motor overload |
(1)In contrast with the required pressure, the stress distinction is massive that the back again pressure or the inlet stress is high (two) When compared with the equipment needs, blower movement is also massive, so its force boosts (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating components (five) The oil stage is also higher (six) Slim V-belt is overheat, vibration is too big, or pulley is as well small |
(one) Lessen the pressure to the specified price (two) Exhaust the excess gas into the ambiance or decrease the blower pace (three) Get rid of the obstructions (four)Instantly shut down, examine the cause (five) Change the oil to the right amount (six) Verify the belt rigidity, and changed it with big diameter pulley. |
