Pressure test system of hydraulic support controller

The utility model provides a pressure testing system of a hydraulic support controller, and belongs to the technical field of pressure testing of hydraulic support controllers. The problem that the pressure detection efficiency of a pressure detection port of an existing hydraulic support controller is low is solved. Comprising multiple sets of hydraulic support controllers, the multiple sets of hydraulic support controllers are connected with a deconcentrator through wires and then connected into a pressure testing device, the pressure testing device comprises a servo motor, a speed reducer, a worm pressure cylinder and an oil filling tank, and an output shaft of the servo motor is connected with an input shaft of the speed reducer through a coupler; an output shaft of the speed reducer is connected with a worm of a worm pressure cylinder through a coupler, a liquid inlet of the worm pressure cylinder is connected with an oil filling tank through a liquid inlet pipe, a first stop valve is arranged on the liq
