Hydraulic metering pump is a device used to provide the flow required by the hydraulic system, often used in industrial production. In order to ensure the normal operation of the hydraulic metering pump and extend its service life, regular maintenance work is required. The following is the hydraulic metering pump maintenance guide and common troubleshooting methods.

First, hydraulic metering pump maintenance guide

1, regular inspection: every once in a while, the hydraulic metering pump for a comprehensive inspection. Including checking whether the connection thread is loose, whether the seal is damaged, whether the pipeline leaks, etc. If suspected problems are found, they should be solved promptly. 

2, lubrication maintenance: all parts of the hydraulic metering pump need to be lubricated. In the process of use, the lubricating oil should be filled regularly, and the aging lubricating oil should be replaced in time. At the same time, the lubrication system should be cleaned regularly to prevent impurities from causing damage to the pump body.

3. Temperature control: The hydraulic metering pump will produce a higher temperature when working, so the temperature of the hydraulic system needs to be controlled. The temperature can be reduced by adding radiators or cooling systems to the hydraulic system.

4. Anti-water measures: the hydraulic metering pump will produce a large recoil when working, in order to protect the pump body from damage, you can set the reversing valve and other measures in the import and export pipes to reduce the impact force.

5. Replace parts regularly: according to the time and frequency of operation of the pump body, replace parts of the hydraulic metering pump regularly. Such as oil seal, sealing ring, etc. After replacement, it is also necessary to test and debug to ensure that it works properly.

Two, common troubleshooting methods

1. Leakage: The hydraulic metering pump may leak during use. It is necessary to check whether the connection threads of the hydraulic system are tight and whether the seals are intact; Secondly, the leakage problem can be solved by adjusting the flow control valve; If the pump body is damaged, it needs to be replaced in time.

2, the pressure is unstable: when the hydraulic metering pump is working, if the pressure is unstable, the performance is that the pressure rises rapidly and then falls, which may be due to the problem of the flow control valve. The problem can be solved by cleaning the flow regulator or replacing the flow regulator with a new one.

3, loud noise: the hydraulic metering pump produces excessive noise when working, which may be caused by aging or wear of seals. At this time, new seals need to be replaced to ensure the normal operation of the hydraulic metering pump.

4, overload protection: in the use of hydraulic metering pump, if there is overload phenomenon, the pump body can not work normally, may be caused by excessive workload. The problem can be resolved by reducing the load or upgrading the device.

5, the temperature is too high: when the hydraulic metering pump is working, if the temperature is too high, it may be due to the failure of the lubrication system or the aging of the hydraulic oil. Need to check the lubrication system and replace the new hydraulic oil to ensure the normal operation of the hydraulic metering pump.

To sum up, the maintenance of hydraulic metering pumps is essential for their normal operation and extended service life. In the process of use, regular inspection, lubrication maintenance, temperature control, anti-water measures and regular replacement of parts. At the same time, for common faults, it is necessary to troubleshoot the problem in time and take appropriate measures to solve it. In this way, we can ensure the normal operation of the hydraulic metering pump and improve production efficiency.
