The working theory of the 3-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. By means of the action 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 gasoline in the chamber is pushed to attain the
purpose of blowing.

Feature of our roots blower:
1. Massive adjustment of the air volume
two. Low Noise
3. Substantial performance
4. Low vitality cosumption
five. Prolonged time lifestyle
6. Reliable operating, simple servicing,little footprint

optimization of the solution and make the solution good quality get to the innovative stage at residence and overseas.
ESR -variety Roots Blower contains several sequence these kinds of as A few-leaves Type, Two-leaves Kind and Centrifugal
Kind,which can be even more divided to hundreds of varieties. The products are widely utilized in sewage remedy,
pneumatic conveying,vacuum packaging, aquaculture, foods processing, EPT electrical power, petrochemical, cement,
mining and other industries. Our items have these kinds of rewards as minimal noise, strength preserving, stable quality,
and prolonged provider daily life, and many others.. With the sales outlets throughout the domestic capital towns, our merchandise promote properly all
above the country, and have been exported to North America,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other international locations. Possessing received the ISO9001 Intercontinental High quality Method Certification, we have
set up and improved the good quality assurance of the goods designing, production, and installation.
From the procedure of design and style, research and development to the concluded products, we have received the complete
procedure controlled independently, therefore delivering the full foundation and trustworthiness ensure for the goods balance
and toughness. Getting a perfect product sales network and soon after-revenue services, we provide our buyers with greater-
high quality and far more productive service.All employees of our company sincerely welcome the wide masses of friends to

The Application of the Roots Blower

Maintenance and inspection
(1) Check all fasteners and locating pins conditions regardless of whether they are loosening.
(2) Constantly check out regardless of whether the leakage phenomenon of the entire body.
(3) Shell out interest to lubrication, quantity of grease and noises when operating,
figure out whether it operates beneath the essential situations.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop point ≥
190ºC). Exchange the lubricant and grease right after initial 200 hours operating, and substitute
once again following a moth managing. Afterwards, exchange the lubricant and grease in accordance to the
atmosphere and lubricant (grease) high quality suggest a suitable EPT for 3
months.
(five) Always examine the inlet air filter, clear or replace the filter in time.
(six) Blower overload sometimes not instantly exhibited, so shell out consideration to
the consumption and exhaust strain, bearing temperature and the existing increase traits
of motor to decide whether or not the blower works usually
(seven) Before disassembling the blower, the assembling relation and proportions
need to be recorded or measured, make marks on elements to ensure the unique
needs following assembling.
(8) When recently machine or overhaul, the oil tank must be cleaned before use
and suggest exchange all grease soon after eight hrs running.

Frequent failure explanation and troubleshooting

No Failure Possible causes Elimination techniques
one Friction
in between the
impeller
(1) Impurities on the impeller,
resulting in the gap is as well tiny
(two) Gear wear, ensuing in a
big backlash
(three) The gear is not properly set,
can not sustain the impeller
synchronization
(4) Bearing put on ensuing in
clearance increasing.
(one) Remove dirt and check
whether there is harm parts
(two) Alter the equipment gap, exchange
the gears if the gear backlash is
greater than the typical thirty% to
50%
(3)Re-assemble the gears, keep
the taper contact region is to 75%
(4)Change the bearing
two Collision
between
impeller and
wall, the
impeller prime
and casing
(one) Set up hole is not proper
(2) running strain is too
high, exceeding the specified
value
(three) Operating temperature is as well substantial
(four) Casing or foundation deformation,
positioning admirer failure
(five) Bearing axial location is not excellent
(one) Adjust the hole
(2) Discover leads to of
overloading, diminished the strain
to the specified worth
(three) Examine the set up
accuracy and minimize the pipe
pressure
(4) Check and repair bearings,
and to guarantee the clearance
(5)Relocation
3 Temperature
as well large
(one) Oil in tank is way too much, as well
thick or also dirty
(2) Filter or silencer is blocked
(3)The pressure is higher than
the specified value
(four)Extreme put on of the
impeller, big gap
(5)Very poor ventilation, indoor
temperature is high, ensuing in
inlet air’s high temperature
(six) The rotating speed is as well reduced,outcome in the belt slipping.
(one)Lessen the oil amount or count on
oil
(two)Take away of blocking objects
(three)Minimizing the pressure via
the blower
(four)Fix its clearance
(5)Open vents to lessen place

leveling the base.
7 Motor
overload
(one)In comparison with the necessary
pressure, the pressure difference
is huge that the back force or
the inlet force is high
(two) In comparison with the
equipment needs, blower
stream is also huge, so its pressure
will increase
(three)Inlet filter is blocked, or outlet
