The operation skills of wear-resistant and corrosion-resistant slurry pumps involve multiple aspects, including preparation before startup, startup operation, operation monitoring, and shutdown operation. Here are some specific operational tips to share:
1, Preparation before startup
1. Check the pump body and components:
-Ensure that the pump body, motor, bearings, and other components are intact and free from damage, cracks, and other issues.
-Check whether the import and export pipelines are firmly connected and whether the valve switches are flexible.
-Check if the electrical control system is functioning properly and if the instruments and protective devices are complete.
2. Check the medium and parameters:
-Confirm the properties of the medium, such as the size and concentration of solid particles, in order to adjust the operating parameters of the pump.
-Check if the model, specifications, and performance parameters of the pump meet the usage requirements.
3. Lubrication and cooling:
-Check if the lubricating oil is sufficient and if the oil quality meets the requirements.
-If the pump is equipped with a bearing cooling water valve, the cooling water valve should be opened.
4. Other preparations:
-If the pump is equipped with a sealing device, find a sealing valve.
-If the pump needs preheating, open the preheating valve for preheating.
2, Start operation
1. Pump filling and exhaust:
-Open the suction valve, close the discharge valve, and perform the pumping operation.
-Drain the air from the pump and ensure that it is filled with the medium.
2. Start the motor:
-Check if the motor direction meets the requirements. If it does not meet the requirements, adjust the motor direction.
-Start the motor and observe its starting condition to ensure smooth operation.
3. Adjust the flow rate:
-After the motor reaches its rated speed, gradually open the drain valve and adjust the flow rate to a moderate level.
-Observe the inlet and outlet pressure of the pump to ensure that the flow rate and head of the pump meet the design requirements.
3, Operation monitoring
1. Check the operating status:
-Regularly check the operation of the pump, such as vibration, noise, temperature, etc., and promptly handle any abnormalities found.
-Pay attention to the inlet and outlet pressure of the pump. If the pressure is abnormal, stop the machine immediately for inspection.
2. Lubrication and cooling management:
-Regularly check the lubricating oil, keep the oil clean, and replace it promptly if the oil quality deteriorates.
-If the pump is equipped with a bearing cooling system, ensure that the cooling water is unobstructed.
3. Sealing inspection:
-Regularly inspect the sealing devices of the pump, such as mechanical seals, packing seals, etc., to ensure that they are in good working condition.
-If serious leakage is found at the seal, the machine should be stopped immediately for inspection and replacement of the seal.
