The functioning theory of the 3-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Through 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 gas in the chamber is pushed to obtain the
function of blowing.
Function of our roots blower:
1. Huge adjustment of the air volume
two. Lower Sound
3. High efficiency
four. Minimal strength cosumption
5. Prolonged time existence
6. Dependable running, simple routine maintenance,tiny footprint

The Software of the Roots Blower
Routine maintenance and inspection
(1) Verify all fasteners and locating pins circumstances whether they are loosening.
(two) Usually verify whether or not the leakage phenomenon of the entire body.
(three) Shell out focus to lubrication, volume of grease and noises when working,
determine whether or not it works below the needed circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall level ≥
190ºC). Exchange the lubricant and grease soon after first 200 hrs managing, and replace
once again right after a moth working. Later, replace the lubricant and grease in accordance to the
setting and lubricant (grease) quality suggest a suitable alternative for 3
months.
(five) Always check out the inlet air filter, clean or change the filter in time.
(6) Blower overload often not quickly shown, so spend consideration to
the consumption and exhaust force, bearing temperature and the recent improve tendencies
of motor to figure out regardless of whether the blower operates generally
(seven) Prior to disassembling the blower, the assembling relation and proportions
should be recorded or calculated, make marks on elements to guarantee the CZPT
demands after assembling.
(eight) When newly machine or overhaul, the oil tank ought to be cleaned ahead of use
and propose substitute all grease after eight several hours working.
Frequent failure explanation and troubleshooting
No | Failure | Achievable causes | Elimination techniques |
one | Friction between the impeller |
(one) Impurities on the impeller, ensuing in the hole is way too small (2) Gear use, ensuing in a massive backlash (three) The equipment is not effectively mounted, can not sustain the impeller synchronization (4) Bearing put on ensuing in clearance increasing. |
(one) Remove grime and verify whether or not there is injury areas (two) Modify the gear gap, exchange the gears if the gear backlash is increased than the average thirty% to fifty% (three)Re-assemble the gears, preserve the taper contact region is to seventy five% (four)Replace the bearing |
two | Collision amongst impeller and wall, the impeller best and casing |
(1) Set up hole is not right (2) working stress is too higher, exceeding the specified benefit (3) Functioning temperature is also large (four) Casing or foundation deformation, positioning enthusiast failure (5) Bearing axial spot is not excellent |
(1) Adjust the gap (2) Identify leads to of overloading, lowered the stress to the specified worth (3) Verify the set up precision and minimize the pipe tension (four) Examine and restore bearings, and to ensure the clearance (5)Relocation |
3 | Temperature as well higher |
(1) Oil in tank is as well a lot, too thick or way too soiled (2) CZPT or silencer is blocked (three)The force is larger than the specified worth (4)Excessive wear of the impeller, massive gap (five)Inadequate ventilation, indoor temperature is higher, resulting in inlet air’s higher temperature (6) The rotating pace is as well lower,result in the belt slipping. |
(one)Reduce the oil amount or rely on oil (2)Eliminate of blocking objects (three)Decreasing the stress via the blower (4)Mend its clearance (5)Open vents to minimize area temperature (6) Increase speed to stop the belt slipping. |
4 | Insufficient circulation |
(1) The inlet filter is blocked (2) Impeller put on and the gap increases also considerably (3) Belt slipping (four) Massive imports pressure loss (five) CZPT air flow leakage |
(1) Clear the filter dust and obstruction (2) Mend the hole (3)Tighten the belt and improve the amount of belts (four)Alter the inlet stress to the specified value (five) Check and restore the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(1)Substantial tank position trigger leakage from the discharge port (2) Seal wear, resulting in shaft oil spills (3) The force is greater than the specified worth |
(1)Lessen the oil amount (2)Replace the seals (three)Distinct the air vents, 2mm diameter faucet is fixed in the middle chamber, open the faucet underneath the wall |
six | Irregular vibration and sounds |
(one)Bearing clearance exceeds the specified price or bearing use (two) The gear backlash is also huge, not in a tight set (three) The international 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 brought on by overload, (five) Friction amongst the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller triggered by fouling or overseas physique (seven) CZPT bolts or other fasteners are loosened |
(one)Substitute bearings or bearing seat (two)Reassemble equipment and guarantee backlash (three)Cleaning blower, verify the scenario is broken (four)Examine the again strain, examine the wheel and change gap (five)Check the filter and back force, enhance the hole in between the impeller inlet and the casing (six)Clean the impeller and the casing, to guarantee that the impeller clearance perform (7) Tighten the anchor bolts and leveling the foundation. |
seven | Motor overload |
(1)In contrast with the required pressure, the stress difference is large that the back again force or the inlet stress is higher (2) When compared with the gear requirements, blower flow is as well big, so its pressure boosts (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating elements (five) The oil amount is also substantial (six) Slender V-belt is overheat, vibration is way too big, or pulley is as well little |
(one) Decrease the force to the specified value (two) Exhaust the extra gasoline into the atmosphere or decrease the blower velocity (3) Get rid of the obstructions (4)Immediately shut down, verify the purpose (5) Adjust the oil to the proper amount (6) Check the belt stress, and changed it with massive diameter pulley. |
