High Performance Roots Type Blower For Sewage Treatment Plant Bend Compact Design
Blower Operation Precautions:
1. After pressure adjustment and the running is normal, pressure meter can be turned off, for extending the service life of pressure meter. In case that new pressure inspection is required, pressure meter switch should be turned on slowly, to avoid any damage to pressure meter due to instant impact.
2. Blower is widely used in the industries of cement, chemical industry, fertilizer, melting, sewage treatment, aquiculture, electrical power, city coal gas, gas transportation etc.. Compared with centrifugal blower, Root’s blower features forceful air blow. In case of pressure change, flow rate change of centrifugal blower is very large, but that of Root’s blower is very little. Correct selection of blower type according to the nature of media transported, flow rate and the pressure required in process flow, can not only guarantee use requirements, but also reduce operating failure rate of blower.
Application:

- Simple structure, free from trouble.
- Highest quality pilot & Accurate great applied, long life and low noise assured.
- Standardized product with strict quality control.
- Our rotor has used the most advanced-one time for all working process of the Four-Shaft method, to enhance the precision of leave wheel.
Blower Operation Precautions:
In order to guarantee normal and safe operation of blower, the operator should carefully read and understand the product operation instruction before going on the duty, and do all inspections and preparations according to requirements of operation instruction; Operation procedure should not be started until everything is confirmed normal. During the operation, running condition of blower should be observed regularly, once abnormal phenomenon is found, stoppage and inspection should be executed at once.
