1.hydraulic unit is made of a pump device, fuel tank, electrical box and so on. 2.it is used with hydraulic screen changer.
Hydraulic unit works principle: motor driven oil pump rotation,and the pump absorbs oil from the tank,then It will convert mechanical energy into pressure energy of hydraulic unit. through the integrated block (or valve combinations), hydraulic oil achieve the direction, pressure, flow rate adjusted. Then through the addition of external piping connected with the hydraulic machinary in the fuel tank or oil motors to control the direction, strength and speed of hydraulic motor and to promot the work of the hydraulic machines.
It is generally used with theHydraulic Screen changer.
