- Jan 30, 2018 -

The electric hydraulic pump control valve plays a very important role in the safe use. Here mainly on the electric hydraulic pump control valve work and the use of attention to a certain understanding.



The electric hydraulic pump control valve includes high pressure relief valve, low pressure unloading overflow valve, high and low pressure one-way valve. Ultra-high pressure manual reversing valve for the middle unloading three-bit four-pass valve for the distribution of the valve, a good resistance to pollution, reversing reliable, convenient maintenance, with pressure-holding function. Ultra-high-pressure manual reversing valve for the middle unloading three-bit four-pass manual slide valve, the valve easy to operate, reversing possible, but does not have a pressure-holding function.



Electric hydraulic pump valve before installation should be designed to check the model, and according to the flow of media to determine the direction of its installation, inspection, cleaning ultra-high pressure electric pumping station valve of the various parts of the dirt, iron oxide crumbs, sand, etc., to prevent the dirty scratches the cover of the valve is very important. Check whether the valve stem of the electric hydraulic pump is askew, the operating mechanism and the transmission device are flexible, test drive is turned on once, check whether can close tightly.


In order to ensure the safety of the use of ultra-high pressure electric pump control valve maintenance and inspection must pay attention to.
