是除砂器，除泥器的供液泵，也是混浆装置的动力。 Sand pump is the dehydrator, the liquid supply pump of the desilter, and the power of the mixing device. It is an indispensable and important equipment in the solid control system. Its parameter design fully considers that the supporting equipment can work under the best conditions. Most parts can be interchanged. It has easy operation and maintenance, low leakage of shaft seals, and reliable operation. , Long life and other advantages.
At the same time, the use of sand pump should pay attention to some matters:
，也绝不允许空气或其他气体进入砂泵进口管线。 1. Never allow two sand pumps to be opened at the same time on the same pipeline, and never allow air or other gases to enter the sand pump inlet pipeline.
2. Never close the small inlet valve to adjust the flow or pressure of the pump, or it will cause cavitation damage to the pump.
3. If you want to reduce the flow of a certain solid control equipment, you cannot use the method of opening the bypass valve of the outlet pipeline, which wastes electricity and overloads the motor. Only some cyclones can be closed at this time.
4. When the pump is started at no load, the valve of the outlet pipe should be closed. Special attention should be paid to the fact that the pump can only run for less than 1-2 minutes in the closed state, otherwise the liquid in the pump will boil quickly. Then the valve on the outlet pipe is gradually opened, and the startup work is not completed until the pump runs smoothly.
5. Do not limit the flow on the suction side of the pump. 入管供应不足会导致空化作用，对泵会造成损坏。 Insufficient supply of pump suction pipe will cause cavitation and damage the pump.
