How to carry out the corresponding maintenance of the refueling machine equipment?

Relatively simple, there is no need to open the oil gun. Mainly, when filling the oil, screw the oil cover and the filter cover tightly. You can determine whether there is a problem with the solenoid valve of the refueling machine equipment by observing whether there is oil overflow from the inside. If there is oil overflow and the oil in the oil mirror does not change, clean the failure for this reason.

You can disassemble the screen cover, remove the screen, and check whether there is oil in the pipeline or the oil pump. It is also a good way to check the electronic valve of the small gear oil refueling machine. The refueling machine must be used in a dull environment, and outdoor operation is prohibited. The installation orientation of the refueling machine equipment manufacturer should conform to the relevant provisions of the corresponding local gas station construction and fire prevention standards. After the initial oil transmission, the oil pump filter should be checked and cleaned to avoid a significant decrease in oil flow and damage to hydraulic components due to filter blockage.
