The correct way to dismantle and install a magnetic pump

Magnetic pump is a high-quality non-leakage transport equipment, in the event of an abnormal failure requires timely disassembly pump repair, mastering the correct method of magnetic pump disassembly is necessary, improper operation will not only damage the pump parts, but also reduce the quality of maintenance, in this regard, into the pump industry on the relevant disassembly steps to make combing introduction, for reference.

In understanding the magnetic pump disassembly correct method before, first of all to do the basic preparatory work beforehand, should be the pump residual media cleaning and pressure drainage, prior to the general condition of the magnetic pump to understand, according to the operation of the fault performance form to determine which parts may be damaged need to replace the new parts, prepare spare parts in advance, and refer to the product manual or disassembly video to understand the internal structure and working principle. Then disassemble and inspect according to the disassembly sequence.

The correct way to disassemble a magnetic pump is as follows.

1, disconnect the power supply and empty the pump medium, prepare the necessary maintenance tools and replacement parts, do not knock the pump body in the disassembly process.

2, pay attention to the order of disassembly should not be reversed, the priority is to remove the auxiliary equipment of the magnetic pump, and then disassemble the pump body from the outside into the inside.

3, first disassemble the coupling and make a good positioning mark, check and record the concentricity and axial clearance of the coupling, then disassemble the ancillary piping, pump cover and shaft head nut in turn.

4. Use both hands to remove the impeller, dismantle the coupling and measure the shaft seal end cap, disassemble the coupling and move the motor to the side. The rotor can be pumped towards the outside, and if required a pure copper rod can be used to tap on the coupling. The seal gland can be dismantled and the bearings at both ends removed as appropriate before the pump shaft is removed.

Above, is the correct method of disassembly of conventional models of magnetic pumps, different models of magnetic pumps in the internal structure of the difference, so the details of the actual operation is different, it is recommended that the operation according to the actual model, before disassembly if not completely sure, can directly consult zhaoquan screw pump industry station technical customer service to obtain professional and detailed technical guidance.
