Metering pump is a kind of equipment used to transport and measure liquids, widely used in chemical, pharmaceutical, food and other industries. After a long time of use, the metering pump may fail or parts are damaged, and timely maintenance and replacement of parts are required. The following will be a detailed description of the metering pump maintenance and replacement parts of the method. Metering pump manufacturers take you to understand


Before servicing the metering pump, the necessary preparations need to be made. Verify that the metering pump is shut down and close the relevant valves and power supply. Second, prepare the necessary tools and spare accessories. Maintenance of metering pumps requires some common tools, such as wrenches, screwdrivers, etc., as well as some accessories that may need to be replaced, such as seals, valves, etc.


When servicing the metering pump, it is necessary to check the appearance and connection of the pump. Check the pump body for obvious damage, corrosion or leakage, and check whether the connection is loose or deformed. If the fault occurs, restore or replace the components in time. Next, it is necessary to check the working state inside the metering pump. Open the manhole on the pump body and observe the pump chamber for any impurities or liquid buildup. If necessary, use a vacuum cleaner or cleaner to clean the pump chamber. Check that the transmission is working properly to ensure that the belt or chain is not loose or worn. Check the motor and electrical control components to ensure that the power supply is properly connected.


After confirming that there is no obvious fault inside the metering pump, you can begin to replace the fittings. The appropriate spare parts need to be selected to ensure that they conform to the specifications of the original parts. For example, select a new sealing ring of the same material and size as the original sealing ring. When replacing parts, you need to unfasten the original connection bolts or screws and carefully remove the original. Before replacing the parts, all the liquid in the hydraulic pump can be drained to ensure safe operation. Then, install the new fittings in the correct position, taking care to secure the bolts or screws. When replacing the seal, it is also necessary to apply an appropriate amount of lubricant to ensure the sealing effect. After replacing the parts, check whether the connection is secure and that there is no loose or oil leakage.


Maintenance of metering pumps also need to pay attention to some common troubleshooting methods. For example, if a metering pump is leaking, it may be a worn or aged seal. At this time, the corresponding sealing ring needs to be replaced. If the metering pump is not stable or the pressure is not up to standard, the valve may be faulty. Can check whether the valve is blocked or worn, timely maintenance or replacement. In addition, if the motor of the metering pump heats up too high, it may be that the motor load is too large or the power supply voltage is unstable. At this time, it is necessary to check the load of the motor, clean up the debris around the motor in time, and ensure that the power supply is normal and stable.

Maintenance of metering pumps requires careful care to ensure safe and correct operation. If you are not clear, you can consult the operating instructions of the metering pump or consult the technical support of the manufacturer. During the maintenance process, pay attention to prevent injuries to the hand or body and prevent accidents caused by liquid leakage. After completing the repair, it is also necessary to test and check to ensure that the metering pump is working properly. For complex maintenance and replacement parts, it is recommended to ask professionals to perform operations to ensure maintenance quality and operation safety.


In short, maintenance of metering pumps and replacement of accessories need to follow certain steps and precautions. Reasonable selection of tools and accessories, check the appearance and internal conditions of the pump body, and careful maintenance and replacement can ensure the normal operation and service life of the metering pump.
