The functioning theory of the 3-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 EPTs, 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 attain the
objective of blowing.
Function of our roots blower:
one. Massive adjustment of the air quantity
two. Reduced Sounds
three. EPT effectiveness
four. Minimal energy cosumption
five. EPTT time daily life
six. Reputable working, straightforward upkeep,modest footprint

The grease is butter (artificial lithium grease penetration 220-250, fall level ge
190 ordmC). Substitute the lubricant and grease soon after first two hundred hrs working, and substitute
again soon after a moth operating. Later on, replace the lubricant and grease according to the
atmosphere and lubricant (grease) top quality suggest a suited substitute for 3
months.
(5) AlwaEPTTcheck the inlet air filter, thoroughly clean or substitute the filter in time.
(six) Blower overload at times not immediately shown, so spend consideration to
the ingestion and exhaust force, bearing temperature and the recent boost tendencies
of motor to deterEPT whether or not the blower operates typically
(seven) Ahead of disassembling the blower, the assembling relation and proportions
need to be recorded or calculated, make marks on factors to ensure the original
needs after assembling.
(eight) When recently EPTT or overhaul, the oil tank must be cleaned prior to use
and propose exchange all grease right after 8 hrs working.
Widespread failure cause and troubleshooting
No |
Failure |
Possible causes |
Elimination techniques |
1 |
Friction among the impeller |
(1) EPTTurities on the impeller, resulting in the hole is as well tiny (two) EPT use, resulting in a large backlash (3) The EPT is not properly mounted, can not maintain the impeller synchronization (four) EPTT use resulting in clearance escalating. |
(one) Get rid of filth and check no matter whether there is injury parts (two) Alter the EPT hole, change the EPTs if the EPT backlash is better than the typical thirty% to 50% (three)Re-assemble the EPTs, preserve the EPTTr contact spot is to 75% (4)Replace the bearing |
two |
Collision between impeller and wall, the impeller prime and casing |
(one) Set up hole is not proper (2) working pressure is way too substantial, exceeding the specified worth (three) Running temperature is as well substantial (4) Casing or foundation deformation, positioning admirer failure (five) EPTT aXiHu (West EPT) Dis.al spot is not excellent |
(1) Change the hole (two) Recognize triggers of overloading, reduced the pressure to the specified worth (three) Check the set up accuracy and decrease the pipe tension (4) Check and fix bearings, and to make certain the clearance (5)Relocation |
three |
Temperature too large |
(one) Oil in tank is too considerably, as well thick or way too soiled (2) EPT or silencer is blocked (three)The force is higher than the specified worth (four)Abnormal use of the impeller, large gap (5)Bad ventilation, indoor temperature is high, ensuing in inlet air’s high temperature (six) The rotating velocity is as well minimal,consequence in the belt slipping. |
(1)Minimize the oil amount or depend on oil (two)Get rid of of blocking objects (3)Decreasing the force by means of the blower (four)Restore its clearance (5)Open vents to lessen space temperature (6) Improve velocity to avert the belt slipping. |
four |
Insufficient movement |
(one) The inlet filter is blocked (2) EPTTeller wear and the hole boosts also significantly (3) Belt slipping (4) Huge EPTTs force loss (five) EPTline ventilation leakage |
(1) Cleanse the filter dust and obstruction (2) Repair the hole (3)Tighten the belt and enhance the number of belts (4)Adjust the inlet pressure to the specified benefit (five) Check out and fix the pipeline |
5 |
Oil leaking or oil leaking into the enclosure |
(1)EPT tank placement cause leakage from the discharge port (2) Seal put on, ensuing in shaft oil spills (three) The stress is greater than the specified price |
(1)Reduce the oil degree (2)Replace the seals (three)Distinct the air vents, 2mm diameter faucet is set in the center chamber, open the faucet unEPTTthe wall |
six |
Irregular vibration and noise |
(one)EPTT clearance exceeds the specified benefit or bearing put on (2) The EPT backlash is way too big, not in a tigEPTT set (three) The overseas objects and dust caused by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation caused the collision induced by overload, (five) Friction amongst the impeller and the inlet housing brought on by overheating (six) Unbalance of the impeller triggered by fJCEP or international body (seven) Anchor bolts or other fasteners are loosened |
(1)Replace bearings or bearing seat (two)Reassemble EPT and make certain backlash (3)Cleansing blower, check the scenario is broken (four)Check out the back again pressure, examine the wheel and alter hole (five)Check out the filter and again stress, boost the hole among the impeller inlet and the casing (6)Thoroughly clean the impeller and the casing, to make certain that the impeller clearance work (7) Tighten the anchor bolts and leveling the foundation. |
7 |
EPT overload |
(one)Compared with the JCEP pressure, the pressure variation is massive that the again force or the inlet strain is high (two) Compared with the products requirements, blower circulation is also large, so its pressure will increase (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (4) Collusion or friction (trapped) rotating parts (five) The oil level is as well large (6) NEPT V-belt is overheat, vibration is too massive, or pulley is as well modest |
(1) Decrease the force to the specified worth (2) Exhaust the surplus gas into the ambiance or lessen the blower pace (3) Get rid of the obstructions (4)Right away shut down, check the reason (five) Modify the oil to the appropriate degree (six) Check the belt pressure, and changed it with big diameter pulley. |
