The working principle of the three-blade roots blower: two 3-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. Through 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 attain the
objective of blowing.

Function of our roots blower:
one. Huge adjustment of the air quantity

Our manufacturing facility is a skilled maker of Roots blowers which has more than twenty years’ experience in equipment
manufacturing. It is located in Xihu (West Lake) Dis. CZPT CZPT Park, 50 kilometers to the east of ZheJiang provincial
capital— HangZhou. Our organization also has handy visitors transportation, as it is 15 kilometers away from
Diaozhen Town station of HangZhou-HangZhou expressway, and thirty kilometers away from CZPT HangZhou station of
ZheJiang -ZheJiang expressway.The leading product of our firm is ESR -kind Roots Blower. The roots
vacuum pump is a new type of higher-efficiency roots blower, which is created independently primarily based on the
domestic and overseas sophisticated technologies. Many patented technologies have been adopted on Roots
Blower, and thus we have produced considerable consequences in energy conservation and noise reduction, and so forth.. So much, our
company has invested far more than thirty,000,000 RMB to introduce these kinds of superior professional tools as
horizontal machining center, vertical machining center, two-way CNC surface planer, CNC lathe, CNC milling
equipment, CNC planer, plane grinder, cylindrical grinding equipment, and 3 coordinates screening machine.
Aside from, we have taken different measures to CZPTize the method stream this sort of as doing work and cooperating
with numerous scientific research units, faculties and universities at property and abroad. We also continuously try to
take in and improve the domestic innovative production systems, so as to market the upgrading and
optimization of the solution and make the merchandise good quality attain the superior stage at home and abroad.
ESR -type Roots Blower includes numerous series such as A few-leaves Type, Two-leaves Kind and Centrifugal
Sort,which can be further divided to hundreds of varieties. The goods are widely utilised in sewage treatment method,
pneumatic conveying,vacuum packaging, aquaculture, foods processing, electric electricity, petrochemical, cement,
mining and other industries. Our items have such benefits as minimal sound, power conserving, steady high quality,
and prolonged service life, and many others.. With the income outlets throughout the domestic capital cities, our merchandise offer effectively all
above the country, and have been exported to North CZPTica,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other countries. Having acquired the ISO9001 CZPT CZPT System Certification, we have
set up and enhanced the good quality assurance of the items developing, manufacturing, and set up.
From the process of design and style, research and advancement to the concluded goods, we have acquired the whole
approach controlled independently, as a result offering the complete basis and reliability promise for the products balance
and toughness. Obtaining a perfect revenue network and soon after-product sales provider, we offer our consumers with higher-
high quality and a lot more productive provider.All workers of our firm sincerely welcome the broad masses of pals to
manual, and negotiate business with us.

The Software of the Roots Blower

Routine maintenance and inspection
(1) Check all fasteners and locating pins situations no matter whether they are loosening.
(two) Usually check out whether the leakage phenomenon of the human body.
(three) Pay interest to lubrication, sum of grease and noises when managing,
determine no matter whether it works beneath the essential situations.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop point ≥
190ºC). Replace the lubricant and grease right after very first two hundred hrs working, and exchange
again right after a moth working. Afterwards, change the lubricant and grease according to the
surroundings and lubricant (grease) high quality propose a ideal substitution for three
(five) Usually check the inlet air filter, clean or exchange the filter in time.
(six) Blower overload occasionally not instantly shown, so pay out attention to
the intake and exhaust strain, bearing temperature and the existing increase tendencies
of motor to establish whether or not the blower operates usually
(7) Prior to disassembling the blower, the assembling relation and proportions
need to be recorded or calculated, make marks on parts to make certain the CZPT
needs right after assembling.
(8) When recently equipment or overhaul, the oil tank should be cleaned before use
and suggest substitute all grease following eight several hours managing.

Widespread failure explanation and troubleshooting

No Failure Possible motives Elimination methods

ensuing in the hole is too modest
(two) Gear use, resulting in a
massive backlash
(3) The equipment is not effectively fastened,
can not keep the impeller
(4) Bearing put on ensuing in
clearance growing.
(one) Get rid of dust and check
whether or not there is damage components
(two) Alter the equipment hole, replace
the gears if the gear backlash is
higher than the average thirty% to
