Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the hydraulic pressure station comprises portable tank 1, air cleaner 3, liquid level gauge 4, water filter 5, filtration unit 6, hydraulic pressure test pump 7, ball valve 8, safety valve 9, retaining valve 10, hydraulic control one-way valve 11, digital display manometer 13 and high-pressure rubber pipe 15; Liquid level gauge 4 is installed on the side of portable tank 1 with filtration unit 6, air cleaner 3, water filter 5, hydraulic pressure test pump 7, is installed on the end face of portable tank 1, and portable tank 1 bottom is equipped with plug screw 2; Digital display manometer 13 is installed on the hydraulic pressure test pump 7, and ball valve 8, safety valve 9, retaining valve 10 and hydraulic control one-way valve 11 are installed in respectively on the pipeline at hydraulic pressure station, and hydraulic control one-way valve 11 is arranged on the top of water filter 5; The two ends of high-pressure rubber pipe 15 are provided with hydraulic quick coupler 14, and portable tank 1 lower end is equipped with deflecting roller, and digital display manometer 13 lower ends are equipped with pressure meter switch 12; This hydraulic pressure station is after pressure rises to set pressure, and power source stops voltage supply, and system gets into packing stage; Dwell time is no less than two hours, in pressure maintaining period, does not allow any pressure compensation, and does not allow a bit leakage; Through our repetition test, the hydraulic pressure station pressure holding function of developing at last is considerably beyond minimum two hours of dwell time and a bit requirement of not leaking, and this is difficult to accomplish in general system; Oil hydraulic system also is difficult to accomplish; Under condition not to the pressure-retaining system pressurising, make pressure-retaining system pressure-retaining system in two hours dwell time not have step-down, there is not pressure drop for making pressure-retaining system pressurize in two hours; Through repetition test; The present invention adopts dual pressurize, and the valve pressurize is adopted in the first road pressurize, and selects the cone valve of pressurize better effects if for use; The retaining valve of cone valve structure is adopted in the second road pressurize, and pressurize is insured more.Evidence, the pressurize system of employing said structure not only reaches but also the dwell time above two hours, and does not have leakage.
The principle of work at hydraulic pressure station is: after all preliminary works are ready, and at first with three ball valves of control element 81,82,83, safety valve 9, retaining valve 10 and hydraulic control one-way valve 11, two digital display manometers 13 of test instrumentation, coupling arrangement hydraulic quick coupler 14 is set in duty with high-pressure rubber pipe 15; With three ball valve valve opens, the source that turns on the power then is if the no abnormal situation of system is closed ball valve valve 81 and 83 and begun to the tested device pressurising; When pressure reached set pressure, first valve-off 82 was opened valve 81 again; Close power source hydraulic pressure test pump 7 simultaneously, make system get into packing stage, packing stage does not allow have any pressure to replenish to system; After two hours, open valve 83, valve-off 81; Open water pump, system begins release, and a working cycle is accomplished at the hydraulic pressure station.
