The functioning principle of the three-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. By way of 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 gasoline in the chamber is pushed to attain the
function of blowing.

Function of our roots blower:
one. Big adjustment of the air volume
2. Minimal Sound
3. EPT performance
4. Lower power cosumption
five. EPTT time existence
six. Reliable operating, easy maintenance,tiny footprint

The Software of the Roots Blower

Servicing and inspection
(one) Verify all fasteners and locating pins conditions regardless of whether they are loosening.
(two) AlwaEPTTcheck whether or not the leakage phenomenon of the entire body.
(three) Pay out interest to lubrication, amount of grease and noises when running,
deterEPT whether or not it performs unEPTTthe JCEP problems.
(4) Lubricant amp grease: The lubricant is for medium load EPTT EPT oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40 ordmC, flash position ge 200 ordmC)
The grease is butter (synthetic lithium grease penetration 220-250, drop point ge
a hundred ninety ordmC). Substitute the lubricant and grease following 1st two hundred hrs managing, and substitute
again after a moth managing. Afterwards, substitute the lubricant and grease according to the
atmosphere and lubricant (grease) good quality propose a appropriate replacement for a few
(5) AlwaEPTTcheck the inlet air filter, clean or exchange the filter in time.
(six) Blower overload at times not right away displayed, so pay out attention to
the ingestion and exhaust pressure, bearing temperature and the recent boost trends
of motor to deterEPT whether the blower operates usually
(7) Just before disassembling the blower, the assembling relation and proportions
have to be recorded or measured, make marks on parts to guarantee the original
specifications after assembling.
(eight) When freshly EPTT or overhaul, the oil tank should be cleaned ahead of use
and suggest exchange all grease after 8 hrs managing.

Widespread failure cause and troubleshooting

No Failure Feasible reasons Elimination strategies
1 Friction
amongst the
(one) EPTTurities on the impeller,
resulting in the hole is as well tiny
(two) EPT dress in, ensuing in a
big backlash
(3) The EPT is not effectively fixed,
can not maintain the impeller
(4) EPTT put on ensuing in
clearance increasing.
(1) Eliminate dirt and verify
regardless of whether there is harm areas
(2) Change the EPT gap, exchange
the EPTs if the EPT backlash is
higher than the common thirty% to
(3)Re-assemble the EPTs, hold
the EPTTr get in touch with area is to 75%
(4)Substitute the bearing
two Collision
impeller and
wall, the
impeller best
and casing
(one) Set up hole is not proper
(two) running stress is too
high, exceeding the specified
(3) Functioning temperature is too high
(four) Casing or base deformation,
positioning enthusiast failure
(five) EPTT aXiHu (West EPT) place is not excellent
(one) Modify the hole
(2) Discover brings about of
overloading, decreased the strain
to the specified worth
(three) Examine the set up
accuracy and minimize the pipe
(four) Check out and repair bearings,
and to make sure the clearance
three Temperature
too high
(1) Oil in tank is way too a lot, also
thick or way too soiled
(2) EPT or silencer is blocked
(three)The pressure is larger than
the specified benefit
(4)Extreme put on of the
impeller, huge hole
(five)Poor air flow, indoor
temperature is large, ensuing in
inlet air’s high temperature
(six) The rotating velocity is way too minimal,end result in the belt slipping.
(1)Decrease the oil stage or rely on
(2)Remove of blocking objects
(3)Reducing the force via
the blower
(4)Mend its clearance
(5)Open up vents to minimize room
(6) Improve speed to avert the
belt slipping.
four Insufficient
(1) The inlet filter is blocked
(two) EPTTeller use and the hole
raises way too much
(three) Belt slipping
(4) Huge EPTTs force reduction
(5) EPTline air flow leakage
(one) Thoroughly clean the filter dust and
(2) Restore the gap
(three)Tighten the belt and improve
the variety of belts
(4)Alter the inlet stress to the
specified benefit
(5) Check out and repair the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)EPT tank placement result in
leakage from the discharge port
(two) Seal put on, resulting in shaft oil spills
(3) The strain is greater than
the specified worth
(1)Minimize the oil degree
(2)Exchange the seals
(three)Very clear the air vents, 2mm diameter faucet is mounted in the
middle chamber, open the faucet
unEPTTthe wall
6 Irregular
vibration and
(1)EPTT clearance exceeds the
specified benefit or bearing dress in
(2) The EPT backlash is as well
big, not in a tigEPTT mounted
(three) The international objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision
caused by overload,
(five) Friction amongst the impeller
and the inlet housing caused by
(6) Unbalance of the impeller
triggered by fJCEP or foreign
human body
(seven) Anchor bolts or other
fasteners are loosened
(one)Exchange bearings or bearing
(2)Reassemble EPT and guarantee
(three)Cleansing blower, check out the
scenario is ruined
(four)Check out the again strain, check out
the wheel and adjust gap
(five)Check the filter and again
stress, boost the hole
among the impeller inlet and the
(6)Clear the impeller and the
casing, to make sure that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the base.
(1)Compared with the JCEP
strain, the stress big difference
is huge that the back again force or
the inlet stress is large
(2) In contrast with the
tools demands, blower
circulation is too big, so its pressure
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating components
(5) The oil level is too substantial
(six) NEPT V-belt is overheat,
vibration is too large, or pulley
is also little
(1) Reduce the force to the
specified worth
(2) Exhaust the excess gasoline into
the atmosphere or minimize the
blower velocity
(3) Remove the obstructions
(four)Right away shut down, check
the cause
(five) Change the oil to the appropriate
(six) Check out the belt stress, and
changed it with large diameter
