Abstract

The utility model discloses a circulating water hydraulic control pump station system, and belongs to the technical field of hydraulic control pump stations. In order to improve the safety of the hydraulic control pump station, an inlet filter screen is respectively connected with one end of an axial plunger pump, one end of a check valve, one end of a stop valve and a manual pump, an overflow valve is arranged on the axial plunger pump, the axial plunger pump is respectively connected with the check valve and a one-way valve, the check valve is connected with one end of the stop valve, and the check valve is connected with the other end of the stop valve. The other end of the one-way valve is connected with the other end of the stop valve, the quick-closing electromagnetic valve, the pressure maintaining electromagnetic valve, the energy accumulator, the cartridge valve and the control cable. A pressure gauge is mounted between the stop valve and the quick-closing electromagnetic valve; the pressure maintaining electromagnetic valve is respectively connected with the main electromagnetic valve and the manual pump; the main electromagnetic valve is connected with a hydraulic lock which is connected with a one-way throttle valve; the quick-closing electromagnetic valve is connected with the cartridge valve, and the cartridge valve and the one-way throttle valve are connected with the oil cylinder through the high-pressure hose; the oil cylinder is respectively connected with the damping block and the travel switch; the control cable is connected with the DCS. According to the utility model, the real-time safety monitoring of the circulating water hydraulic control pump station system is realized.
