Debugging Method of Submersible Slurry Pump

The following are three debugging methods of submersible slurry pumps.

1. Before starting the submersible slurry pump, the rotor of the rotating pump should be smooth and even. Close the outlet gate valve and fill the pump with water. Make sure that the pump is filled with water and there is no air trapped. If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected to the submersible slurry pump and then start the motor. Open it again after the speed is normal, and then gradually open the outlet gate valve. If the flow rate is too large, you can close the gate valve appropriately. Adjust, otherwise the flow is too small, open the gate valve.

​2. Tighten the compression nut on the packing gland evenly to allow the liquid to leak out in drops. At the same time, pay attention to the temperature rise outside the packing chamber. When stopping the operation of the submersible slurry pump, first close the cocks and outlets of the vacuum gauge and pressure gauge. The gate valve on the water pipeline, and then cut off the power to the motor. If the temperature of the environment is low, the square screw plug at the bottom of the pump body should be opened to remove the remaining water to prevent frost cracking.

​3. During operation, the bearing temperature should not exceed 75 degrees. The amount of calcium-based butter used to lubricate the bearing should be 1/3-1/2 of the space of the old bearing body. When the packing is worn, the packing pressure can be appropriately tightened. Cover, if worn excessively should be replaced. During the operation of the submersible slurry pump, it is important to pay attention to details and phenomena, and deal with problems in a timely manner to prevent losses during operation.
