Pump industry suppliers to tell you: the adverse impact that magnetic pump idling

the idling the ill effects of magnetic pump introduction

idling caused multiple parts of the magnetic pump, a pump body, magnetic steel, magnetic steel, static ring, impeller, isolation cover, pump shaft, the damage of the thrust ring, sealing ring, etc. In the process of using magnetic pump, idle is the cause of many failures, so the user must understand the magnetic water pump is not free, then small make up simple explain why magnetic pump are not allowed to idle, the main reasons are as follows:

1, the pump after the empty, no material cooling pump, so direct combustion diaphragm is possible. Magnetic pump can't idle, because the magnetic water pump magnetic cylinder is composed of a cooling medium, if the air will lead to magnetic cylinder lock.

2, the core component of magnetic pump is magnetic components and magnetic components. If idle, core components will demagnetization at high temperatures and demagnetization after magnetic pump performance will be greatly reduced.

in addition, in order to guarantee the use of magnetic pump stability, regular maintenance equipment is also a way to reduce equipment failure rate, including:

1, magnetic pump, pump shaft front with stuffing box, reliable sealing function. On the bearing seat is equipped with mechanical seal device at the same time, such a large number of leakage, will happen through a small amount of leakage and leakage mouth to start a small amount of leakage of the starting operation is normal, inner sealing surface in a certain period after the operation, leakage will reduce or stop.

2, there are two ball bearing housings, for the transport of heat conduction oil lubrication pump magnetic pump impeller side of a ball bearing, by the side of the coupling is a ball bearing with high temperature lubricating grease: each ball bearing in operation after 3000 hours, must remove the clean diesel engine inspection, the contact surface is damaged, if there are any damage, new bearing must be replaced.

3, monitor the looseness of the anchor bolt, stainless steel pump magnetic pump shell is consistent with the inlet temperature, temperature fluctuation and the vibration of the water pump outlet pressure gauge. Magnetic pump under the design discharge should not be less than 30% of the continuous operation. If it is necessary to run under this premise, by-pass pipe should be installed at the exit, traffic will reach the minimum value.
