ISG, IHG series chemical pipeline centrifugal pump maintenance 1, the operation of the maintenance: (1), the inlet pipe must be filled with liquid, the pump is prohibited long-term operation under cavitation. (2), regularly check the motor current value, must not exceed the motor rated current. (3) When the pump is operated for a long time, due to mechanical wear, noise and vibration of the unit should be stopped and checked. If necessary, the vulnerable parts and bearings can be replaced. The overhaul period of the unit is generally one year. 2, mechanical seal maintenance: (1), mechanical seal lubrication should be clean without solid particles. (2) It is forbidden to work mechanical seal in dry grinding condition. (3) If the medium viscosity or easy to crystallize, stop using steam to clean the pump, so as not to damage the mechanical seal the next boot.
