Abstract

The utility model discloses a pumping unit hydraulic control system which is characterized by comprising a power drive module and an oil line module. The power drive module comprises an oil box, an actuating unit I and an actuating unit II. The oil box is provided with a liquidometer, a liquid level controller, an air filter and a temperature controller. The actuating unit I comprises a plunger pump and a motor. The actuating unit II comprises a plunger pump and a motor. A butterfly valve is arranged between each plunger pump and an oil outlet of the oil box. A one-way valve is arranged on an oil outlet of each plunger pump. The one-way valve is connected with a pressure gage through a pressure measuring connector and a pressure measuring flexible pipe. The oil line module comprises an electro-hydraulic directional control valve I and an electro-hydraulic directional control valve II. The electro-hydraulic directional control valve I and the electro-hydraulic directional control valve II are connected with an energy accumulator through high pressure ball valves. An electromagnetic unloading valve is arranged between the electro-hydraulic directional control valve I and the actuating unit I, and the electro-hydraulic directional control valve II is connected with an overflow valve. The pumping unit hydraulic control valve has the advantages of being simple in structure, high in control sensitivity and automation degree and beneficial for saving energy and improving working efficiency.
