Cast Iron Vertical 3 Lobe Roots Blower Discharge Pressure Calculation Low Space Saving
Notes for Specification Table:
1. The performance parameter indicate the type, caliber,revolutions, discharge pressure, actual inlet air capacity and shaft power of the blower.
2. The performance parameter indicate the air quantity in standard suction condition (temperature 20, absolute pressure 1.0332 kgf/cm2 and relative e humidity 65%) .
3. The reference air capacity (temperature 0 and absolute pressure 1.0332kgf/cm2) is generally indicated in Nm3/min.

Blower Operation Precautions:
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.

Fault and Trouble Shooting:
Abrasion between the impeller and the wall | 1.Clearance between C, D exceeds allowed value. | 1. Adjust the clearance between C, D. |
2. Foreign matters or media fouling adhere to the impeller and wallboard end face. | 2. Remove foreign matters and fouling. | |
3. Abrasion of rolling bearing, windage increase. | 3. Replace. | |
Bearing damage | 1. Lubricating quality is bad or oil supply amount is insufficient. | 1. Replace. |
2. Consequent bearing damage in short time is caused due to contacting with corrosive gas (coal gas) after ineffective gas seal. | 2. Replace the bearing, repair gas seal. | |
3. Operate with overload for long term. | 3. Replace. | |
4. Exceed the rated service life. | 4. Replace. | |
The motor not running | 1. The problem of electrical wiring. | 1. Overhaul electrical wiring. |
2. Motor is damaged. | 2. Overhaul or replace the motor. | |
3. Foreign object in the body. | 3. Remove foreign object. | |
4. Too high resistance of outlet/inlet piping of blower. | 4. Remove piping obturator or open inlet/outlet valve. |
