Magnetic pump running condition analysis

by:J&T     2020-09-30

general magnetic pump is suitable for chemical plants and chemical industry, the commonly used magnetic pump raw materials such as stainless steel, fluorine plastic raw materials may be carbon steel. Each kind of raw material is different, the function of the magnetic pump according to the actual transport medium to decide. Due to the magnetic force pump medium often poisonous, harmful, corrosive, high temperature or low temperature, and thus require magnetic pump can meet the demand of chemical process, no leakage or less leakage, corrosion resistance, wear resistance, resistance to high temperature or low temperature, can be critical state of liquid, and stable operation.

bearing overheating: if found in the operation of the pump bearing hot, can be in the following several screen its reason: different heart, pump and electric coupling on the bad or the axial gap is too small, is to check on the status and adjust the axial gap and smooth oil shortage or smooth oil circulation and smooth oil quality is poor, have impurities to make bearing corrosion, wear and tear, turn the insensitive, bearing has severe wear, bearing blow grind owe good, should take out the bearing bush back blow grind or replace new bearing, bearing gap is too small, it should readjust the bearing gap or bad blow grind bearing, bearing installation, should check bearing as required installation condition, eliminate undesirable factors, cooling water circuit, should immediately check repair, equipment cooling water pump shaft bending, you should correct the pump shaft and other factors.

in normal operation condition, magnetic pump bearing temperature generally are no more than 80 degrees Celsius, the highest temperature control on daily, if discover bearing temperature is higher than 60 degrees Celsius, will need to check the oil level and smooth oil cooling water piping condition, sometimes may be due to the tank into the foreign body; On the operating procedures, when suspended magnetic pump operation, need to close the outlet valve, then close pressure gauge, finally to suspend the motor running.

in the magnetic pump corrosion can affect the internal components of the wet surface or a small, is the general or highly part. Generally, caused by highly part and the affected parts pump failure. Therefore, magnetic water pump to find a solution can reduce corrosion influence is very important.
