Cast Iron Roots Rotary Lobe Blower, capacity
3600m3/hour roots lobe blower
Roots blower is a kind of volumetric blower whose air capacity and
revolution have formed a proportion. Each rotation of the
three-lobe type blower needs three times of air suction&
discharge of two-lobes. Compared to two-lobe type blower, three
lobe roots blower have the characteristics of low air pulsation and
more stable operation.
It has two lobes on the two parallel bearings. There are small tiny
spaces between lobes, elliptic casing as well as each lobe. he
lobes' uniform speed rotation at opposite directions makes the
certain quantity air circled by casing and lobes transported
form the suction side to the discharge side.

Assembling drawing of blower package
Standard supply of scope
1. shaft blower
2. inlet silencer (with air filter)
3. outlet silencer
4. relieve valve
It is a safety device on the system. When the system works abnormally and the resistance is higher than the rated value, the pressure relief valve opens to discharge the air from the pressure relief valve to prevent the blower and motor from being overload.
5. check valve
It is used to prevent back-flow of high-pressure air in the system during shutdown. The back-flow can cause blower reversion and then cause blower malfunctions. The valve body is made of cast iron.
6. flexible joint
7. pressure gage
8. blower pulley and motor pulley
9. V-belt
10. belt cover
