Industrial Blower Manufacturers
Sernies ZR large-size high-pressure rotary blower and Vacuum Pumps is developed based on rich manufacture experience,whichis a advanced product to be satisfied with customer’s requirement of large capacity and high pressure rotary blower.
It is not onlyabsorbed the technology soul from series RR rotary blower, which is introduced technology and series L rotary blower, but alsoadopted the special rotor profile, which makes rotary blower be high efficiency and energy saving.
Rotor with approximate involute profile, advanced and reasonable, hiah eficiency overal.
Main parts are machined by machining center and NC faclities, among which bearing reaches to class 5 accuracy. The
product is high accuracy and runs reliably.
Oil tank has new structures of oll-plate etc., good heat emision. Cooling water isn’t used when pressure rise doesn’ t
exceed 49kPa.which can lower occupating expenses.
Casing and headplate adopt misplit structure in horizon, which can make check and repair convenient.
Combined with our rich manufacturing experience and the technology of RR Roots blowers and L roots blowers, ZR blowers are developed by using special impeller profile to realize high efficiency and energy saving.
Features
lInvolute profile is applied to the impellers to get high efficiency.
lKey parts are machined by machining center, gears are made in alloy steel and reach class 5 accuracy.
lNew structure is applied to oil tank to get better oil lubricating. Air cooling for the pressure rise of 49 Kpa.
lDual splash lubrication
lBlower casings and head plates are mid-split structure to make easy maintenance.
Duty
Flow：317.9～1258m3/min；
Pressure rise：9.8～98kPa.
Applications
For large flow applications in Power, petroleum, chemical, metallurgy, cement, and air-separating industries.
