Check whether there is any foreign matter blocking the water inlet of the plunger pump. In addition, you can also check whether the pointer of the pressure gauge changes after the machine is running. If the above external reasons are all gone. It is estimated that the plunger pump itself has a problem.
The air-conveying sprayer and the boom sprayer match the plunger pump only when the medicine box is below 500L.
In addition, check the oil position of the plunger pump to avoid idling the machine when there is no oil, otherwise it will cause great damage to the machine.
If the filter of the water machine is blocked, the pressure will also be low. If the water inlet and outlet pipes shake during use, it means that there is a problem with the valve group in the medicine machine. Clean or replace it.
If the belt is too loose and easy to slip, the pressure will also be low. If the pressure valve at the outlet is too worn and cannot suppress the water, the water outlet will be small and the pressure will also be low. If the power is small and does not match the medicine machine, the pressure of the medicine machine will also be low. It is more troublesome to repair the automatic pressure regulator, and it is easier to repair the semi-automatic one.
