We – EPG Group the most significant couplings and gears manufacturing unit in China with five distinct branches. For much more particulars: Cellular/whatsapp/telegram/Kakao us at: 0086-13083988828 /

We make all varieties of roots blower, centrifugal blower, Our Main items are as below:

The working principle of the a few-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the motion 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
function of blowing.

Feature of our roots blower:
one. Massive adjustment of the air quantity
two. Reduced Sound
three. Substantial efficiency
4. Lower energy cosumption
five. Prolonged time life
6. Reliable managing, easy servicing,little footprint

Our manufacturing facility is a skilled producer of Roots blowers which has in excess of 20 years’ experience in equipment
manufacturing. It is located in Xihu (West Lake) Dis. East Industrial Park, 50 kilometers to the east of Shan EPT provincial
funds— HangZhou. Our organization also has convenient targeted traffic transportation, as it is 15 kilometers absent from
Diaozhen Town station of HangZhou-HangZhou expressway, and thirty kilometers away from East HangZhou station of
ZheJiang -ZheJiang expressway.The leading merchandise of our organization is ESR -sort Roots Blower. The roots
vacuum pump is a new type of large-performance roots blower, which is produced independently based on the
domestic and overseas advanced technologies. Several patented technologies have been adopted on Roots
Blower, and therefore we have created substantial effects in vitality conservation and noise reduction, etc.. So much, our
business has invested a lot more than thirty,000,000 RMB to introduce such innovative professional gear as
horizontal machining center, vertical machining centre, two-way CNC surface planer, CNC lathe, CNC milling
equipment, CNC planer, aircraft grinder, cylindrical grinding machine, and 3 coordinates screening device.
Besides, we have taken numerous actions to standardize the process movement such as operating and cooperating
with many scientific research units, schools and universities at home and overseas. We also constantly consider to
take in and improve the domestic advanced creation technologies, so as to advertise the upgrading and
optimization of the merchandise and make the product high quality get to the superior degree at home and overseas.
ESR -type Roots Blower includes a number of series this sort of as Three-leaves Sort, Two-leaves Kind and Centrifugal
Kind,which can be additional divided to hundreds of versions. The items are commonly utilised in sewage treatment,
pneumatic conveying,vacuum packaging, aquaculture, foodstuff processing, EPT electrical power, petrochemical, cement,
mining and other industries. Our items have these kinds of rewards as minimal sounds, vitality saving, steady top quality,
and lengthy services daily life, etc.. With the product sales outlets throughout the domestic money cities, our items market nicely all
more than the country, and have been exported to North America,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other countries. Having got the ISO9001 International Good quality Technique Certification, we have
set up and enhanced the good quality assurance of the products planning, manufacturing, and set up.

The Application of the Roots Blower

Routine maintenance and inspection
(one) Verify all fasteners and locating pins conditions whether or not they are loosening.
(two) Constantly examine regardless of whether the leakage phenomenon of the entire body.
(3) Pay focus to lubrication, amount of grease and noises when running,
determine whether it performs beneath the essential situations.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall stage ≥
190ºC). Replace the lubricant and grease right after 1st 200 several hours running, and substitute
once again following a moth running. Later on, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) good quality propose a ideal EPT for a few
months.
(5) Always check the inlet air filter, cleanse or substitute the filter in time.
(six) Blower overload often not instantly displayed, so pay interest to
the ingestion and exhaust pressure, bearing temperature and the recent increase tendencies
of motor to determine no matter whether the blower performs generally
(seven) Before disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on factors to make sure the authentic
needs right after assembling.
(8) When newly equipment or overhaul, the oil tank ought to be cleaned just before use
and propose replace all grease right after eight hrs running.
