DC single-acting manual valve control hydraulic drive unit

   DC single-acting manual valve control hydraulic drive unit    DC single-acting hydraulic pump is the 1 common type of hydraulic pump, which is mainly used to generate DC hydraulic energy. Compared with other types of hydraulic pumps, DC single-acting hydraulic pumps have the following characteristics:     1.  DC single-acting hydraulic pumps can only produce hydraulic energy in one direction, usually pushing outward or retracting inward. During operation, the plunger or gear of the pump can only move in one direction.     2. DC single-acting hydraulic pump is powered by DC power supply, which converts electrical energy into mechanical energy to generate hydraulic energy. This pump is suitable for applications that require continuous production of hydraulic energy, such as hydraulic machinery, construction machinery, etc.     3. DC single-acting hydraulic pump is usually composed of pump body, driving device, cont…
