There are several points we should pay attention to when installing the double suction mid open pump, including before starting and when the pump stops running. Let's cut the crap and take a closer look.

1. Before starting, the rotor of the pump shall be rotated gently and evenly.

2. Tighten the compression nuts on the packing gland evenly to make the liquid leak out in drops. At the same time, pay attention to the temperature rise at the packing chamber.

3. When the water pump is stopped. First close the cocks of the vacuum gauge and pressure gauge and the gate valve on the outlet pipe. Then turn off the power to the motor. If the ambient temperature is low, open the square screw plug at the lower part of the pump body. Remove water. To avoid frost cracking.

4. Close the water outlet gate valve and inject water into the pump without ensuring that the pump is full of water. No air pockets.

5. When it is not used for a long time. The water pump shall be disassembled to dry the water on the other part. Apply antirust oil on the machined surface and keep it well.

6. If the pump is equipped with a vacuum gauge or pressure gauge. Turn off the screw base connected to the pump before starting the motor. Open it after the speed is normal; Then gradually open the outlet gate valve. If the flow position is too large, properly close the gate valve to adjust; On the contrary, the flow is too small. Open the gate valve.
