The operating theory of the a few-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. Through the action of a pair of
synchronous EPTs, the two rotors rotate in reverse 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 achieve the
objective of blowing.
Characteristic of our roots blower:
one. Massive adjustment of the air quantity
two. Minimal Sound
3. EPT performance

The Application of the Roots Blower
Upkeep and inspection
(one) Examine all fasteners and finding pins situations no matter whether they are loosening.
(two) AlwaEPTTcheck whether or not the leakage phenomenon of the physique.
(3) Shell out attention to lubrication, amount of grease and noises when working,
deterEPT whether or not it performs unEPTTthe JCEP conditions.
(4) Lubricant amp grease: The lubricant is for medium load EPTT EPT oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40 ordmC, flash stage ge 200 ordmC)
The grease is butter (artificial lithium grease penetration 220-250, drop level ge
190 ordmC). Change the lubricant and grease following first 200 hours managing, and substitute
again soon after a moth managing. Afterwards, exchange the lubricant and grease according to the
environment and lubricant (grease) high quality propose a suitable alternative for three
months.
(five) AlwaEPTTcheck the inlet air filter, cleanse or exchange the filter in time.
(6) Blower overload at times not right away exhibited, so spend interest to
the consumption and exhaust pressure, bearing temperature and the existing increase traits
of motor to deterEPT regardless of whether the blower works typically
(seven) Prior to disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on elements to ensure the original
specifications after assembling.
(8) When freshly EPTT or overhaul, the oil tank need to be cleaned prior to use
and suggest exchange all grease right after 8 hours working.

| 4 | Inadequate flow |
(1) The inlet filter is blocked (two) EPTTeller dress in and the gap will increase way too considerably (three) Belt slipping (4) Large EPTTs stress loss (5) EPTline air flow leakage |
(one) Clean the filter dust and obstruction (2) Mend the hole (three)Tighten the belt and improve the variety of belts (4)Change the inlet strain to the specified price (five) Check and restore the pipeline |
| 5 | Oil leaking or oil leaking into the enclosure |
(one)EPT tank position cause leakage from the discharge port (two) Seal wear, resulting in shaft oil spills (three) The pressure is increased than the specified benefit |
(one)Reduce the oil degree (2)Replace the seals (3)Clear the air vents, 2mm diameter faucet is set in the center chamber, open up the faucet unEPTTthe wall |
| 6 | Abnormal vibration and sound |
(one)EPTT clearance exceeds the specified price or bearing use (2) The EPT backlash is as well huge, not in a tigEPTT set (3) The overseas objects and dust induced by the impeller and the impeller, the impeller and the housing collision (4) the impeller shaft deformation brought on the collision induced by overload, (5) Friction in between the impeller and the inlet housing triggered by overheating (6) Unbalance of the impeller induced by fJCEP or international human body (7) Anchor bolts or other fasteners are loosened |
(1)Exchange bearings or bearing seat (2)Reassemble EPT and make certain backlash (three)Cleansing blower, verify the circumstance is ruined (four)Check out the back pressure, examine the wheel and adjust gap (five)Verify the filter and again pressure, boost the gap between the impeller inlet and the casing (six)Clear the impeller and the casing, to guarantee that the impeller clearance operate (7) Tighten the anchor bolts and leveling the foundation. |
| 7 | EPT overload |
(one)Compared with the JCEP strain, the strain variation is massive that the back again strain or the inlet force is large (two) When compared with the equipment needs, blower movement is also massive, so its stress boosts (three)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (caught) rotating components (5) The oil level is way too high (six) NEPT V-belt is overheat, vibration is as well big, or pulley is too little |
(one) Decrease the strain to the specified worth (two) Exhaust the surplus fuel into the ambiance or minimize the blower pace (three) Remove the obstructions (4)Quickly shut down, check the reason (five) Change the oil to the right stage (6) Check the belt pressure, and changed it with huge diameter pulley. |
