Mechanical seal lubrication should be clean with no solid particles. It is strictly prohibited to mechanical seal dry grinding work carbon steel flange.

Should be acting pump several times before start. Otherwise should check. In order to avoid sudden start fracture damage caused by graphite carbon steel flange. 3 drops/minute of seal leakage amount allowed.

A, carbon steel flanges control cabinet maintenance:

Maintain indoor and ventilated, dry.

If the voltage is 380 v2 control cabinet to whether have the supply.

Wire is loose. 3 regular blackouts check control components contained in the normal.

Regularly check whether the pipe is air leakage, leakage.

Second, the maintenance of the pump:

Ban pump in the condition of gas cloud long running carbon steel flange. 1 imported pipe must be filled with liquid.

Must not overstep the motor rated current. 2 check the motor current value.

Pump after a long run. Noise and vibration of generating unit, due to mechanical wear and tear. Should stop check and, if necessary, can replace quick-wear part and bearing, unit big general maintenance for one year.
