High temperature magnetic pump common fault reason analysis and processing

high temperature magnetic pump common fault reason analysis and handling

is varied, the cause of high temperature magnetic pump fault common has unreasonable type selection and equipment inherent problem, installation, start-up and operation. For example, because of unreasonable selection form pump power; cavitation for planning production defect serious insufficient and flow; Because of device to form the vibration and noise of the pump serious cost overruns; Because of the startup and operation of the pump pump can't start properly and water yield gradually reduce, packing such as fever, bearing overheating.

work abnormal sound or vibration pump work, the pump and motor of small units should be smooth, the sound should be normal. If the small units with noise or abnormal vibration, often is the forerunner of pump problem, it is necessary to stop the machine immediately to check, eliminate hidden dangers.

present fault reasons may be: pump and motor rotors imbalance, of the pump and motor, the aging of the wheel aprons, balance is not correct, machine impeller pump foundation stiffness is insufficient, anchor bolt looseness, bearing and seal wear too much, the formation of the rotor eccentricity, pump with gas, not into a vacuum, bearing and packing improper lubrication, wear, bearing wear, or have too much damage, lubricating oil, Fat) Too much or too little, suck the bout, import produce cavitation impeller, liquid through present bubbles in low pressure area, the impeller to the high air bubbles breaking, touch attack caused by vibration of at this time should reduce the plant height of pump and pump suction eyewinker, blocked or damaged impeller, should stop cleaning foreign matter or replace the damaged impeller, resonance caused by vibration, mainly on the natural frequencies of the rotor and the pump rotating speed is the same, the resonance, and so on.

let's look at the different ways to reduce corrosion! It not only can help you to save millions of dollars, but will also extend the service life of pump.

1, choose high temperature magnetic pump data

in solving the problem of corrosion, should first consider the data selected. It is not just to deal with the corrosion problems, but also can choose the best material according to the operating conditions of high temperature magnetic water pump to reduce the degradation rate.

cast iron has a relatively low corrosion resistance, can reduce the function of the pump of agile. So, water pump producers use stainless steel to prevent corrosion.

please note that the right choose is ultimately the responsibility of the user data. Only users to relative to the concentration, temperature and so on to control the pumping liquid. is the responsibility of the producers under the condition of the physical good supply information selected and satisfy the requirement of the rules of the hydraulic supply the correct chemical composition at the same time. High temperature magnetic pump in practice, a reliable pump supplier will be based on his experience of previous applications involving a similar service supply.
