Abstract

The invention discloses a hydraulic station for a lift. The hydraulic station comprises a motor pump set and an oil tank. The motor pump set comprises a motor, a plunger pump and a small filter. The plunger pump is connected with an oil outflow pipe on the oil tank. The oil outflow end of the plunger pump is connected with the small filter. The small filter is connected with a group valve. The output end of the group valve is connected with a hydraulic cylinder of the lift. An electricity box is arranged on the oil tank. The side of the oil tank is provided with an air cooler. The input end of the air cooler is connected with an oil return pipeline of the hydraulic cylinder. The output end of the air cooler is connected with an oil return filter. An output end pipeline of the oil return filter is inserted into the oil tank. The hydraulic station is designed for the lift, and the hydraulic station has the beneficial effects of being simple in structure and high in control efficiency and is very suitable for small lifts.

Description

Technical field: [0001] The invention relates to the technical field of hydraulic pump station equipment, in particular to a hydraulic station of an elevator. Background technique: [0002] The hydraulic station is an important part that provides power for the elevator. When the elevator is lifted, some are driven by electric control, and some are driven by a hydraulic station. The hydraulic station is mainly composed of hydraulic pumps, motors, fuel tanks, directional valves, and relief valves. The hydraulic source device connects the hydraulic pump station with the oil cylinder of the valve, and the hydraulic system can realize various specified actions. The motor drives the oil pump to rotate. The pump pumps oil after absorbing oil from the oil tank, and converts mechanical energy into pressure energy. [0003] However, the lift hydraulic pump station in the prior art generally has the problems of poor flexibility and inability to realize real-time flow and direction adj...
