Introduction to the causes of venting during the startup of Roots blower

Roots blower is a kind of equipment designed and manufactured according to Roots principle. It is a positive displacement blower and has the characteristics of forced gas transmission. If Roots blower is vented during startup, what is the reason? Next, I want you to understand the cause of venting when Roots blower starts.

1、 Motor; The motor voltage is constant, the speed is constant, the demand force is greater, and more work is done. When the motor power increases, the current increases too much, and the protection system stops. The motor without protection system is burnt out

2、 Fan; The fan is heated by compressed gas, and the heat cannot be discharged in time. Fan heating, softening and embrittlement of fan casing! The fan is subject to two external forces at the same time.

1. The strong torque of the motor to the main shaft and bearing of the fan.

2. The outward thrust of the air pressure in the inner chamber on the fan casing, combined with heat and force, will cause the fan to burst, or even explode.

3、 The reason for system pipes and valves is the same as above. There are many damaged valves and burned flanges.
