The operating principle of the 3-blade roots blower: two 3-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Via the action of a pair of
synchronous gears, the two rotors rotate in opposite 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
function of blowing.

Characteristic of our roots blower:
1. Large adjustment of the air quantity
2. Low Sound
3. Higher efficiency
four. Minimal power cosumption
5. Extended time life
6. Reputable running, effortless maintenance,small footprint

Roots blower pack method exact same as iron scenario, just modify to Fumigation Free Plywood Case

Our manufacturing unit is a skilled company of Roots blowers which has over 20 years’ experience in machinery
manufacturing. It is positioned in Xihu (West Lake) Dis. East Industrial Park, 50 kilometers to the east of Shan EPT provincial
funds— HangZhou. Our firm also has practical traffic transportation, as it is fifteen kilometers away from
Diaozhen City station of HangZhou-HangZhou expressway, and thirty kilometers away from East HangZhou station of
ZheJiang -ZheJiang expressway.The leading solution of our firm is ESR -variety Roots Blower. The roots
vacuum pump is a new kind of substantial-performance roots blower, which is produced independently based on the
domestic and foreign advanced technologies. Many patented technologies have been adopted on Roots
Blower, and thus we have created substantial effects in power conservation and noise reduction, etc.. So considerably, our
organization has invested more than 30,000,000 RMB to introduce these kinds of superior skilled tools as
horizontal machining heart, vertical machining centre, two-way CNC area planer, CNC lathe, CNC milling
device, CNC planer, aircraft grinder, cylindrical grinding equipment, and a few coordinates screening machine.
Besides, we have taken various actions to standardize the procedure movement these kinds of as working and cooperating
with several scientific research units, colleges and universities at house and abroad. We also continually try out to
take up and enhance the domestic innovative creation technologies, so as to promote the upgrading and
optimization of the solution and make the merchandise top quality get to the advanced stage at residence and overseas.
ESR -sort Roots Blower contains a number of sequence such as 3-leaves Variety, Two-leaves Sort and Centrifugal
Sort,which can be even more divided to hundreds of kinds. The products are extensively employed in sewage treatment,
pneumatic conveying,vacuum packaging, aquaculture, meals processing, EPT electrical power, petrochemical, cement,
mining and other industries. Our products have such benefits as reduced sounds, strength saving, stable high quality,
and lengthy support lifestyle, and so on.. With the revenue outlets throughout the domestic capital cities, our products sell effectively all
over the country, and have been exported to North The us,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other international locations. Getting obtained the ISO9001 Global Top quality Program Certification, we have
set up and enhanced the top quality assurance of the merchandise designing, producing, and set up.
From the method of layout, investigation and improvement to the completed items, we have received the whole
process managed independently, as a result supplying the entire basis and trustworthiness assure for the items security
and durability. Obtaining a perfect product sales community and following-income services, we supply our customers with larger-
good quality and much more effective support.All personnel of our organization sincerely welcome the broad masses of friends to
manual, and negotiate enterprise with us.

The Application of the Roots Blower

Maintenance and inspection
(one) Examine all fasteners and finding pins problems regardless of whether they are loosening.
(two) Often check out whether or not the leakage phenomenon of the physique.
(three) Pay consideration to lubrication, quantity of grease and noises when running,
decide whether or not it works under the essential conditions.
(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 stage ≥
190ºC). Exchange the lubricant and grease right after 1st 200 several hours managing, and substitute
again soon after a moth managing. Later on, change the lubricant and grease according to the
environment and lubricant (grease) high quality propose a suitable EPT for a few
(five) Often check out the inlet air filter, clear or change the filter in time.
(6) Blower overload sometimes not quickly shown, so shell out interest to
the consumption and exhaust pressure, bearing temperature and the recent enhance tendencies
of motor to decide whether or not the blower performs usually
(7) Ahead of disassembling the blower, the assembling relation and proportions
must be recorded or measured, make marks on elements to guarantee the unique
demands right after assembling.
(8) When freshly device or overhaul, the oil tank need to be cleaned ahead of use
and propose substitute all grease following eight several hours operating.

Typical failure reason and troubleshooting

No Failure Achievable motives Elimination techniques
one Friction
among the
(1) Impurities on the impeller,
ensuing in the hole is as well modest
(2) Gear dress in, ensuing in a
big backlash
(three) The gear is not well set,
can not maintain the impeller
(four) Bearing put on resulting in
clearance escalating.
(1) Remove filth and check out
no matter whether there is harm components
(two) Alter the gear gap, substitute
the gears if the gear backlash is
increased than the common thirty% to
(3)Re-assemble the gears, hold
the taper speak to location is to 75%
(four)Substitute the bearing
two Collision
in between
impeller and
wall, the
impeller prime

(1) Set up gap is not appropriate
(2) running strain is way too
high, exceeding the specified
(three) Working temperature is too high
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial location is not great
(1) Change the hole
(2) Discover brings about of
overloading, reduced the pressure

(three) Examine the set up
precision and minimize the pipe
(4) Check and fix bearings,
and to make sure the clearance
3 Temperature
way too high
(1) Oil in tank is also much, also
thick or also soiled
(two) Filter or silencer is blocked
(3)The force is increased than
the specified value
(four)Excessive wear of the
impeller, massive hole
(five)Bad air flow, indoor
temperature is higher, resulting in
inlet air’s high temperature
