The functioning theory of the a few-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Via the motion of a pair of
synchronous gears, the two rotors rotate in opposite directions 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
purpose of blowing.
Function of our roots blower:
1. Massive adjustment of the air quantity
two. Reduced Sound
3. High effectiveness
four. Reduced vitality cosumption
five. Prolonged time existence
six. Trustworthy running, effortless upkeep,little footprint

Servicing and inspection
(one) Verify all fasteners and finding pins conditions no matter whether they are loosening.
(two) Always check out regardless of whether the leakage phenomenon of the human body.
(3) Shell out interest to lubrication, amount of grease and noises when operating,
establish regardless of whether it functions underneath the essential conditions.
(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 (synthetic lithium grease penetration 220-250, drop stage ≥
190ºC). Exchange the lubricant and grease following first two hundred several hours operating, and substitute
again following a moth working. Later on, change the lubricant and grease according to the
atmosphere and lubricant (grease) top quality suggest a appropriate substitute for three
months.
(5) Constantly verify the inlet air filter, clear or substitute the filter in time.
(six) Blower overload often not immediately displayed, so pay out consideration to
the ingestion and exhaust stress, bearing temperature and the present improve trends
of motor to figure out whether or not the blower works normally
(seven) Prior to disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on components to make sure the CZPT
needs right after assembling.
(eight) When freshly machine or overhaul, the oil tank must be cleaned prior to use
and propose substitute all grease right after eight several hours running.
Frequent failure cause and troubleshooting
No |
Failure |
Attainable motives |
Elimination techniques |
one |
Friction among the impeller |
(one) Impurities on the impeller, resulting in the gap is also small (two) Gear put on, ensuing in a large backlash (3) The equipment is not properly set, can not preserve the impeller synchronization (four) Bearing put on ensuing in clearance rising. |
(one) Get rid of grime and verify whether there is injury parts (two) Change the gear gap, substitute the gears if the gear backlash is increased than the average 30% to fifty% (3)Re-assemble the gears, keep the taper speak to region is to 75% (4)Replace the bearing |
2 |
Collision among impeller and wall, the impeller leading and casing |
(one) Installation hole is not right (two) running stress is as well substantial, exceeding the specified value (3) Working temperature is too higher (4) Casing or foundation deformation, positioning fan failure (five) Bearing axial location is not excellent |
(one) Alter the gap (2) Identify brings about of overloading, reduced the pressure to the specified worth (3) Verify the set up precision and lessen the pipe rigidity (4) Check out and restore bearings, and to make certain the clearance (5)Relocation |
3 |
Temperature too higher |
(one) Oil in tank is way too considerably, way too thick or as well dirty (2) CZPT or silencer is blocked (3)The strain is increased than the specified value (4)Too much dress in of the impeller, big hole (five)Very poor ventilation, indoor temperature is higher, resulting in inlet air’s higher temperature (6) The rotating speed is way too lower,result in the belt slipping. |
(1)Reduce the oil amount or depend on oil (two)Take away of blocking objects (3)Decreasing the strain via the blower (four)Mend its clearance (5)Open up vents to minimize area temperature (6) Improve pace to prevent the belt slipping. |
four |
Inadequate movement |
(one) The inlet filter is blocked (two) Impeller use and the gap boosts also much (3) Belt slipping (four) Large imports strain decline (5) CZPT ventilation leakage |
(1) Thoroughly clean the filter dust and obstruction (2) Repair the gap (three)Tighten the belt and improve the variety of belts (four)Modify the inlet stress to the specified value (5) Verify and repair the pipeline |
5 |
Oil leaking or oil leaking into the enclosure |
(one)Substantial tank situation lead to leakage from the discharge port (two) Seal dress in, ensuing in shaft oil spills (3) The strain is greater than the specified price |
(one)Reduce the oil amount (two)Substitute the seals (three)Clear the air vents, 2mm diameter faucet is fastened in the middle chamber, open the faucet under the wall |
6 |
Irregular vibration and sounds |
(1)Bearing clearance exceeds the specified worth or bearing wear (two) The equipment backlash is way too large, not in a tight mounted (3) The international objects and dust induced by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation induced the collision brought on by overload, (5) Friction among the impeller and the inlet housing triggered by overheating (six) Unbalance of the impeller triggered by fouling or international body (7) CZPT bolts or other fasteners are loosened |
(one)Substitute bearings or bearing seat (two)Reassemble equipment and make certain backlash (3)Cleaning blower, examine the circumstance is destroyed (four)Verify the back stress, check the wheel and adjust hole (five)Check out the filter and again pressure, improve the gap in between the impeller inlet and the casing (6)Clear the impeller and the casing, to ensure that the impeller clearance perform (seven) Tighten the anchor bolts and leveling the base. |
seven |
Motor overload |
(one)Compared with the required stress, the strain big difference is large that the again stress or the inlet force is substantial (2) When compared with the tools requirements, blower flow is way too massive, so its stress increases (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (caught) rotating parts (five) The oil amount is too high (6) Slender V-belt is overheat, vibration is as well big, or pulley is way too modest |
(1) Reduce the strain to the specified value (2) Exhaust the surplus gasoline into the environment or minimize the blower velocity (three) Take away the obstructions (4)Immediately shut down, check the cause (5) Adjust the oil to the proper amount (six) Check the belt rigidity, and changed it with big diameter pulley. |
