Anti-corrosion self-priming magnetic pump start-up and shutdown

Some users do not understand the importance of starting and stopping the anti-corrosion self-priming magnetic pump, and very often, a small detail may lead to subsequent failure. Let's talk about anti-corrosion self-priming magnetic pump start-up and shutdown operation precautions

Precautions for starting the anti-corrosion self-priming magnetic pump

1. Make sure the suction valve is fully open and the discharge valve is closed or slightly open. When there is a small flow line, the discharge valve should be fully closed and the smaller flow valve should be fully opened.

2、Close the check valve of the outlet line of the self-priming pump, which must ensure a smaller flow rate.

3、Start the anti-corrosion self-priming magnetic pump motor, make the pump rotor reach the running speed.

4, slowly open the export valve to make the pump export pressure and flow rate to the specified value, open the export valve at the same time should check the motor current change to prevent motor overload. The pump vibration condition is normal, the pump body and motor have no abnormal sound, the export pressure change, etc. If the self-priming pump has abnormal leakage, the cause should be identified and dealt with.

5、When the self-priming pump is put into normal work, you need to check the pump outlet pressure, outlet flow, motor current, bearing and seal temperature, and other conditions.

Precautions for anti-corrosion self-priming magnetic pump shutdown

1、Self-priming pump block the power, stop the pump, close the export valve, self-priming pump slowly closes the small discharge valve until the flow reaches a smaller flow stop.

2、When the anti-corrosion self-priming magnetic pump has a small flow bypass line, close the discharge valve when the bypass valve is fully open, and then stop the pump by blocking the power.

3, self-priming pump maintenance, stop the pump (cooling), first close the dry gas sealing system nitrogen inlet valve, the seal chamber pressure relief, and then completely discharge the liquid in the pump and cooling water in the cooling system. Make the pressure in the pump body drop to zero, the residual material in the pump blow clean, all the valves are closed, and contact with the substation power off.

In order to reduce unnecessary verification and maintenance costs, it is recommended to arrange for professional technicians to operate the pump.

Taicang magnetic pump Co., Ltd. was born in 1979. It cooperated with Shanghai Chemical Design Institute to form a unique core research project with magnetic drive pump, and achieved great success. It has become the first company in China to comprehensively design and produce magnetic drive pump. Today, Taicang magnetic pump Co., Ltd. has become a leading manufacturer of magnetic drive pumps in China, with many patents and 12 utility model patents.
