The working 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 both sides of the cavity. By means of the motion of a pair of
synchronous gears, 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
purpose of blowing.

Characteristic of our roots blower:
1. Massive adjustment of the air quantity
2. Lower Sounds
three. Large effectiveness
4. Minimal power cosumption
5. Long time life
6. Reliable working, simple upkeep,tiny footprint

The Software of the Roots Blower

Servicing and inspection
(one) Check all fasteners and locating pins conditions no matter whether they are loosening.
(two) Usually check out whether or not the leakage phenomenon of the human body.
(three) Pay consideration to lubrication, quantity of grease and noises when working,
figure out whether it performs below the needed conditions.
(four) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall stage ≥
190ºC). Exchange the lubricant and grease following very first 200 hrs operating, and replace
again following a moth operating. Later, replace the lubricant and grease in accordance to the
setting and lubricant (grease) good quality suggest a ideal replacement for 3
months.
(five) Always examine the inlet air filter, cleanse or change the filter in time.
(6) Blower overload often not instantly exhibited, so pay out focus to
the ingestion and exhaust pressure, bearing temperature and the existing boost traits
of motor to figure out whether or not the blower functions generally
(7) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on parts to make certain the CZPT
requirements after assembling.
(8) When newly device or overhaul, the oil tank ought to be cleaned before use
and propose change all grease soon after eight hrs operating.

Typical failure explanation and troubleshooting

No Failure Achievable causes Elimination methods
1 Friction
in between the
impeller
(one) Impurities on the impeller,
ensuing in the gap is way too tiny
(2) Equipment put on, ensuing in a
large backlash
(three) The equipment is not properly set,
can not maintain the impeller
synchronization
(four) Bearing dress in ensuing in
clearance increasing.
(1) Get rid of dirt and verify
whether or not there is hurt parts
(2) Alter the equipment gap, substitute
the gears if the gear backlash is
increased than the typical 30% to
fifty%
(3)Re-assemble the gears, hold
the taper contact spot is to 75%
(four)Substitute the bearing
two Collision
amongst
impeller and
wall, the
impeller top
and casing
(one) Installation hole is not right
(two) working pressure is as well
higher, exceeding the specified
value
(three) Functioning temperature is as well higher
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial location is not excellent
(one) Modify the gap
(two) Determine triggers of
overloading, lowered the pressure

casing, to ensure that the impeller
clearance perform
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(one)When compared with the necessary
pressure, the strain distinction
is large that the back again pressure or
the inlet force is substantial
