The operating theory of the three-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the motion of a pair of
synchronous EPTs, the two rotors rotate in reverse directions 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.

Servicing and inspection
(one) Check out all fasteners and finding pins conditions regardless of whether they are loosening.
(2) AlwaEPTTcheck whether the leakage phenomenon of the physique.
(3) Spend attention to lubrication, sum of grease and noises when operating,
deterEPT whether it works unEPTTthe JCEP situations.
(4) Lubricant amp grease: The lubricant is for medium load EPTT EPT oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40 ordmC, flash level ge two hundred ordmC)
The grease is butter (artificial lithium grease penetration 220-250, drop stage ge
190 ordmC). Substitute the lubricant and grease right after very first two hundred several hours managing, and replace
once again following a moth operating. Afterwards, exchange the lubricant and grease in accordance to the
atmosphere and lubricant (grease) good quality suggest a suited alternative for a few
months.
(five) AlwaEPTTcheck the inlet air filter, clear or substitute the filter in time.

(one)EPTT clearance exceeds the specified price or bearing wear (two) The EPT backlash is way too large, not in a tigEPTT fastened (3) The foreign objects and dust brought on by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation triggered the collision caused by overload, (5) Friction among the impeller and the inlet housing caused by overheating (six) Unbalance of the impeller induced by fJCEP or international physique (seven) Anchor bolts or other fasteners are loosened |
(1)Substitute bearings or bearing seat (two)Reassemble EPT and make sure backlash (three)Cleansing blower, examine the case is destroyed (four)Examine the back again stress, verify the wheel and alter gap (5)Check out the filter and back stress, improve the hole among the impeller inlet and the casing (6)Clean the impeller and the casing, to ensure that the impeller clearance function (7) Tighten the anchor bolts and leveling the foundation. |
seven | EPT overload |
(1)When compared with the JCEP pressure, the pressure distinction is large that the back strain or the inlet pressure is high (two) In contrast with the gear requirements, blower movement is as well large, so its force increases (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating areas (5) The oil level is as well substantial (six) NEPT V-belt is overheat, vibration is also big, or pulley is too little |
(one) Minimize the stress to the specified worth (2) Exhaust the extra gasoline into the atmosphere or decrease the blower speed (three) Remove the obstructions (four)Immediately shut down, check the explanation (5) Change the oil to the correct level (six) Check the belt tension, and replaced it with big diameter pulley. |
