Detailed description of the invention

The utility model is described in further detail for 1 to Fig. 2 and detailed description of the invention below in conjunction with the accompanying drawings.

If Fig. 1 is to shown in 2, the hydraulic means of a kind of disc type protection controller that lost efficacy of this utility model, is by fuel tank 1, thick Filter 2, gear pump 3, motor 4, check valve 5, manual pump 6, overflow valve 7, electromagnetic valve 8, pressure switch 9, pressure meter switch 10, Pressure gauge 11, adjustable throttling 12, accumulator 13, air filter 14, liquidometer 15, electric box 16, drain oil 17 and go out Oilhole 18 forms, and described coarse filter 2 is fixed on the upper right side of fuel tank 1 inwall, and described motor 4 passes through gear pump 3 with thick Filter 2 solidity connects, and described pressure switch 9 is designed with check valve 5, overflow valve 7 and electromagnetic valve 8, described pressure Relay 9 is fixed on the left side within fuel tank 1, and described manual pump 6 is connected with pressure switch 9 right-hand member solidity, described pressure Power table 11 is fixed on the lower-left end within pressure switch 9, and described pressure meter switch 10 is by adjustable throttling 12 and pressure Table 11 connects, and described accumulator 13 is fixed on the left upper end within fuel tank 1, and described air filter 14 is fixed on fuel tank 1 Internal lower end, described liquidometer 15 is fixed on the lower-left end of fuel tank 1 outer surface, and described electric box 16 is fixed on fuel tank 1 Internal bottom righthand side, the positive lower end of described fuel tank 1 outer surface is designed with drain oil 17, the appearance of described pressure switch 9 The left end in face is designed with oil outlet 18.Described fuel tank 1 is designed to square build.Described coarse filter 2 is a kind of ISV- 24A-100W-E pipeline oil absorption filter.Electronic control: open a sluice gate and pressurize, when Hydraulic Station obtains electric, electromagnetic valve 8 obtains electric pressurize, machine Structure performs switching-off action.Sending signal when system pressure reaches the operating pressure of pressure switch 9 design, motor 4 stops fortune Turning, system is in pressurize duty.Close lock: hydraulic pressure power loss, make electromagnetic valve 8 power-off burst pressure, reset action.Manually Control: open a sluice gate, after stirring manual pump 6 handle aerofluxus back and forth, screw the manual knob of manual adjustable throttle valve 12, stir hands Dynamic pump handle is suppressed, and mechanism performs switching-off action.Closing lock: thoroughly unclamp the manual knob of manual adjustable throttle valve 12, mechanism is multiple Bit motion.For safety, first it is operated manually before pumping plant is energized, first confirms that Hydraulic Station is connected with brake piping and whether arrive Position, checks whether pressure meter switch 10 opens (to left-handed for opening), adjustable throttling 12 is closed (to dextrorotation for closing), dials Dynamic manual pump starts to suppress, and observes pressure gauge reading, and till getting to brake operation oil pressure, regulation relief valve 7 can regulate hands The high output pressure of dynamic pump, pressurize more than ten minutes, observe whether pipeline exists oil leakage phenomenon, observe whether brake beats Open, if all going well, adjustable throttling 12 being opened, system pressure is laid down, carry out electric operating.Access according to wiring diagram Electrical source of power and control power supply, before power transmission, first press the air switch in electric box, and measuring voltage with circuit tester is It is no that correctly close air switch QF1, QF2 successively, when close QF2 time motor 4 start running, observe the rotation direction of motor 4 and sign Whether be consistent, turn off main power source if not being inconsistent, change power phase, repeat the above steps, from small to large regulation pressure relay Device 9, and observe Pressure gauge 11 reading, motor 4 stall when regulation makes Hydraulic Station arrive operating pressure repeatedly.

Above in conjunction with accompanying drawing, this utility model is exemplarily described, but this utility model is not limited to above-mentioned Mode, as long as using the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out or directly applying In other occasion, all fall within protection domain of the present utility model.
