Remote pressure regulating load sensitive hydraulic station

Abstract

The invention discloses a remote pressure regulating load sensitive hydraulic station. The hydraulic station comprises an oil tank module communicated with a remote industrial control PLC (programmable logic controller), a motor pump module, a high-pressure manifold module, a pressure regulating and pressure relief manifold block module, an electric control module and a display alarm module, themotor pump module comprises at least three sets of constant-pressure pump sets, each set of constant-pressure pump set is respectively connected with an inlet of the safety valve and an inlet of the high-pressure filter, an outlet of the high-pressure filter is collected to a pressure port P of the hydraulic station, the pressure port P of the hydraulic station is connected with the pressure portof the single-machine equipment for drilling, the oil return port of the equipment is communicated with the oil return port R of the hydraulic station, the oil return port R is connected with the inlet of the oil return filter through a socket pressure valve, the oil return filter is communicated with the oil tank, the oil discharging port of the constant-pressure pump set and the connecting pipeline of the oil tank are provided with an oil discharging filter. The pressure of the outlet of the hydraulic station can be automatically adjusted, remote pressure regulation of an operator can be realized through a PLC, the labor intensity is reduced, and the efficiency is improved.
