Description
The utility model relates to a kind of high pressure pick-up unit, belongs to a kind of UHV (ultra-high voltage) pressure testing measuring station that is applicable to that the sealing to high-tension apparatus and parts, compressive resistance are measured.
At present, domestic existing large and medium-sized pressure testing station is fixed, its used pressure source all is the single-stage ram pump that boosts, because the effect of shock wave makes the gauge hand amplitude of fluctuation big, read untrue, the rate of rise is fast in addition, pressure test pressure is difficult to control, and is slightly careless, and the overload accident will take place.In order to guarantee the control accurately (error≤3%) of boosting, required pressure is controlled, need to be equipped with the pulpit.Next is that single-stage ram pump pressure one-level puts in place, and pump and all pipelines, valve all are in work under the UHV (ultra-high voltage) state, also need be equipped with a cover security protection facility, as: underground explosion-proof cell or insulated chamber etc. need the about 300M of factory building in addition
2Therefore there is not only the cost height in this fixed pressure testing station, investment is big, standing charges are high, charge is high, and can not mobile operational process, can only sit back and wait the user to the doorstep, deficiency such as plant factor is low.
Fundamental purpose of the present utility model is to make low, the small investment of UHV (ultra-high voltage) pressure testing measuring station cost.
A purpose of the present utility model also is to make UHV (ultra-high voltage) pressure testing measuring station safe and reliable.
Another purpose of the present utility model is to make UHV (ultra-high voltage) pressure testing measuring station energy mobile operational process.
Fundamental purpose of the present utility model is to realize like this, it comprises forcing pump, valve, tensimeter, pipeline, also comprise supercharge pump, a side is established small liquid jar in the housing of supercharge pump, its opposite side is established big fluid cylinder, big piston in valve piston in the small liquid jar and the big fluid cylinder is to be connected as a single entity by piston rod, the big small liquid jar manhole appendix that respectively establish at the housing two ends of supercharge pump; Forcing pump be the size two plungers, the forcing pump outlet is handled the voltage supply pipe by first and is linked to each other with second threeway, second threeway, one end is handled the voltage supply pipe by second and is linked to each other with ultra-high pressure stopped valve, second threeway end is in addition linked to each other with first threeway with second stop valve by the second manipulation voltage supply pipe, and first threeway end is in addition linked to each other with big fluid cylinder manhole appendix by first air release by first high-voltage tube; Ultra-high pressure stopped valve is linked to each other with universal joint by four-way, second air release by first super high pressure bend, and four-way end is in addition linked to each other with the small liquid jar manhole appendix by second super high pressure bend; The import of supercharge pump fuel tank is linked to each other with second air release by charge pump by oil inlet pipe.
A purpose of the present utility model is achieved in that establishes safety valve on forcing pump; Establish adjustable soft dynamic sealing device at the valve piston front end of supercharge pump, adjustable soft dynamic sealing device is to be shaped as
The small end head of cylinder sleeve on establish external thread, space suit " zero " shape O-ring seal and back-up ring on the outer wall of cylinder jachet between big termination of cylinder sleeve and the small end head, loading nut on small end head is used to adjust back-up ring and compresses " zero " shape O-ring seal degree, promptly is to have adjusted seal degree.
Another purpose of the present utility model is achieved in that in the supercharge pump lower housing portion establishes supporting leg, and active pin is established in the supporting leg lower end.
The utility model is owing to be provided with a supercharge pump that can play the high pressure vessel effect, can reduce the pressure pump capacity, the rate of rise slows down, also slowed down shock wave, make gauge hand steadily to rise, the pressure test pressure control accuracy by≤3% bring up to≤1.5%, therefore can save expensive pulpit; Because the utility model is when boosting, close ultra-high pressure stopped valve, except that parts such as first and second super high pressure bend that links to each other with supercharge pump small liquid jar one end, four-way, universal joint are in the UHV (ultra-high voltage) state, remaining part all is in lower high pressure conditions (about 330kg/cm
2), dwindled the security protection scope greatly, the adjustable soft dynamic sealing device may command top pressure of in supercharge pump, establishing, also has the safety valve on the forcing pump, it also is the restriction top pressure, all play the safeguard protection effect, so the utility model has saved the investment of building underground explosion-proof cell and isolation facility; Also because the utility model is three pumps combination, has the boost function of four kinds of discharge capacities of secondary.Secondary boosts: promptly forcing pump rises to 600kg/cm with medium by normal pressure
2, again by supercharge pump with 600kg/cm
2Pressure increases to 2000kg/cm
2Four kinds of discharge capacities: promptly forcing pump is a duplex plunger pump, and two plungers of size are arranged, and big plunger is used for perfusion, 6.4 liters/minute of discharge capacities, and small plunger is used to boost, and discharge capacity is 2.7 liters/minute.Forcing pump can have two kinds of discharge capacities through supercharge pump: 2.7 ÷ 6.76=0.4 liters/minute, 6.4 ÷ 6.76=0.94 liters/minute, without supercharge pump, directly enter a kind of discharge capacity of test specimen: 6.4 liters/minute, add 25 liters/minute of charge pump discharge capacities.Therefore but centering pressure, high pressure, high pressure, four inferior pressure of retaining of UHV (ultra-high voltage) are tested, and also can test large, medium and small, extra small pressure chamber test specimen, and are of many uses.Because the utility model is divided into the active pin of supporting leg at pump case, but therefore also have the characteristics of mobile operational process.
Fig. 1 is the structural representation of the utility model embodiment
Fig. 2 is the adjustable soft dynamic sealing device structural representation among the utility model embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is described.
