The operating theory of the 3-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the action of a pair of
synchronous EPTs, 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.

Feature of our roots blower:
one. Big adjustment of the air quantity
2. Reduced Sounds
three. EPT effectiveness
four. Reduced energy cosumption
5. EPTT time existence
six. Reliable operating, straightforward upkeep,tiny footprint

Our manufacturing unit is a expert maker of Roots blowers which has more than 20 years’ experience in EPTTry
production. It is found in XiHu (West EPT) (West EPT) Dis. EPT EPTT Park, 50 kilometers to the EPT of ZheJCEP provincial
cash— EPTEPTTn. Our firm also has handy targeted traffic transportation, as it is 15 kilometers away from
Diaozhen Town station of EPTTngdao-HangEPT expressway, and thirty kilometers away from EPT EPTEPTTn station of
BeiEPTTg-ZheJCEP expressway.The top merchandise of our firm is ESR -sort Roots Blower. The roots
EPT pump is a new variety of substantial-effectiveness roots blower, which is deveXiHu (West EPT) Dis.Hu (West EPT) Dis.ed independently dependent on the
domestic and foreign EPTd technologies. A number of patEPTTd systems have been adopted on Roots
Blower, and therefore we have made substantial effects in vitality conservation and noise reduction, and so forth.. So far, our
company has invested far more than 30,000,000 RMB to introduce these kinds of EPTd professional gear as
horizontal machining cEPTTr, vertical machining cEPTTr, two-way CNC floor planer, CNC lathe, CNC milling
EPTT, CNC planer, plane grinder, cylindrical grinding EPTT, and three coordinates screening EPTT.
Besides, we have taken a variety of steps to stXiHu (West EPT) Dis.Hu (West EPT) Dis.rdize the method circulation such as operating and cooperating
with a lot of EPT research models, faculties and universities at home and abroad. We also continuously try to
absorb and improve the domestic EPTd creation systems, so as to promote the upgrading and
optimization of the item and make the merchandise top quality achieve the EPTd stage at house and overseas.
ESR -kind Roots Blower incEPTTs a number of collection this kind of as 3-leaves Kind, Two-leaves Kind and Centrifugal
Kind,which can be further divided to hundreds of types. The items are extensively utilised in sewage remedy,
pneumatic conveying,EPT EPTT, aquaculture, food processing, electric powered EPTT, petrochemical, cement,
mining and other EPTT. Our products have these kinds of benefits as reduced noise, vitality conserving, stable top quality,
and EPTT service existence, and many others.. With the product sales stores through the domestic cash cities, our products offer effectively all
in excess of the region, and have been exported to North America,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other international locations. Possessing got the ISO9001 JCEP EPTT Program Certification, we have
estabEPTTd and improved the high quality assurance of the items developing, manufacturing, and set up.
From the procedure of style, research and deveXiHu (West EPT) Dis.Hu (West EPT) Dis.ment to the concluded items, we have acquired the EPTT
approach controlled independently, as a result providing the complete basis and reliability promise for the products stability
and toughness. Obtaining a excellent revenue network and following-sales services, we provide our clients with larger-

The Software of the Roots Blower

Routine maintenance and inspection
(1) Examine all fasteners and finding pins problems whether they are loosening.
(two) AlwaEPTTcheck no matter whether the leakage phenomenon of the entire body.
(three) Pay out attention to lubrication, volume of grease and noises when working,
deterEPT no matter whether it performs unEPTTthe JCEP situations.
(four) Lubricant amp grease: The lubricant is for medium load EPTT EPT oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s forty ordmC, flash point ge two hundred ordmC)
The grease is butter (synthetic lithium grease penetration 220-250, fall stage ge
a hundred ninety ordmC). Change the lubricant and grease after first two hundred hrs working, and change
yet again right after a moth working. Later on, substitute the lubricant and grease according to the
environment and lubricant (grease) good quality suggest a ideal substitute for a few
(five) AlwaEPTTcheck the inlet air filter, clean or replace the filter in time.
(6) Blower overload at times not immediately displayed, so pay out attention to
the consumption and exhaust pressure, bearing temperature and the current enhance traits
of motor to deterEPT whether the blower functions normally
(seven) Before disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on components to ensure the first
demands after assembling.
(eight) When newly EPTT or overhaul, the oil tank should be cleaned ahead of use
and suggest replace all grease following eight several hours running.

Frequent failure cause and troubleshooting
