The composition and working principle of a small hydraulic station

The small hydraulic station is an important hydraulic control unit in the hydraulic control system. The hydraulic station is mainly composed of a plunger pump, a cooling pump system, a filter, an electromagnetic spill valve, a two-position two-way reversing valve, a throttle valve, and a manual ball valve. , pressure gauge, one-way stop valve, relief valve, thermostat, pressure sensor, heater, disc brake, accumulator, proportional control valve, globe valve, remote thermostat, oil level relay and so on.

How small hydraulic stations work:

The hydraulic pump consists of a plug-in variable pump with overload protection and a single-speed motor, which is used to supply pressure to the hydraulic control components. When the brake is released, the accumulator reaches its maximum pressure. After the release of the brakes, the hydraulic pump only needs to provide the loss pressure to compensate for the energy of the system. The variable hydraulic pump automatically reduces the flow output and maintains system pressure.
