China slurry pump - testing method of submersible slurry pump
1.Before starting the submersible slurry pump, the rotor of the rotating pump should be smooth and even, the water gate valve should be closed, and the pump should be filled with water to ensure that the pump is filled with overflow and no air. If the pump is equipped with a vacuum gauge or a pressure gauge, turn off the cock connected to the submersible slurry pump and restart the motor, and then turn it on after the speed is normal.
2.Then gradually open the water gate valve. If the flow rate is too large, the small gate valve can be properly closed to stop the adjustment. On the contrary, if the flow rate is too small, the gate valve will be opened. Next, tighten the compression nut on the packing gland evenly to make the liquid leak out in a drop shape, and pay attention to the temperature rise outside the packing cavity.
3.Before and after the submersible slurry pump is used to debug the method and stop the operation of the submersible slurry pump, first close the cock of the vacuum gauge and the pressure gauge and the gate valve on the outlet pipe, and then cut off the power supply of the motor. , The square screw plug at the bottom of the pump body should be turned over to remove the remaining water to avoid frost cracking.
4.During operation, the maximum temperature of the bearing should not exceed 75 degrees. The quantity of calcium-based butter for smooth oil bearings is preferably 1 / 3-1 / 2 of the space of the ancient bearing body. When the packing is worn, the packing gland can be properly compressed If excessive wear should be replaced. The whole debugging process of the submersible slurry pump is mainly the above five tasks, mainly to pay attention to the details and the phenomena that appear during the operation process, and handle the problems in time to prevent the accidental loss during the work.
