The utility model for the foregoing reasons, has proposed a kind of employing water as test(ing) medium, air drum is carried out to the hydraulic test system of withstand voltage test.
In order to realize the purpose of this utility model, intend adopting following technology:
A kind of automobile air cylinder resistance to pressure pilot system, comprise water tank (1), supercharge pump (7) and control system (12), between described supercharge pump (7) and control system (12), be disposed with solenoid directional control valve (8), safety valve (9), pressure regulator valve (10), between described pressure regulator valve (10) and control system (12), be also provided with filtrator (11), described supercharge pump (7) is also provided with hand supercharging handle (70).
Further, described supercharge pump (7) is gas drive liquid supercharge pump.
Further, described control system (12) is mainly made up of operation valve (120) and throttling valve (121), and described operation valve (120) is connected with pressure transducer (6).
Further, between described water tank (1) and supercharge pump (7), be also provided with filtrator (2), high-pressure unloading valve (3) and retaining valve (4), filtrator (2) is arranged on the inlet pipeline between water tank (1) and pressure charging valve (7), and high-pressure unloading valve (3) is arranged on the water return pipeline between water tank and pressure charging valve (7).
Further, on described supercharge pump (7) water under high pressure output pipe, be also provided with high-pressure stop valve (5) and pressure transducer (6).
Further, described high-pressure stop valve (5) is needle-valve.
The advantage of technique scheme is:
1, the utility model can be realized Automatic-boosting to supercharge pump by control system on controlling, and also can carry out hand supercharging to supercharge pump by hand supercharging handle, two kinds of control modes, and separate, can flexible Application under actual use occasion.
2, the connecting line in the utility model is tracheae and sebific duct, tracheae and sebific duct length are unrestricted, can realize remote auto control, at utmost guarantee test operation personnel's safety, simultaneity factor gas circuit coupling part all adopts the pneumatic components and parts of SMC, can repeatedly dismantle.High-pressure section is prone to the high-pressure hose part of potential safety hazard most, and the high-pressure hose that all selection work pressure is 40MP guarantees safety test,
3, native system can produce the pressure within the scope of 25Mpa, therefore can expand practical withstand voltage to other pressure vessels in, in experiment as withstand voltage in brake piping, braking clamp etc., and in system, all stop valves are needle-valve, can ensure well system sealing.This system also can expand in sealing for pressure vessels test and go.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described further;
A kind of automobile air cylinder resistance to pressure pilot system, comprise water tank (1), supercharge pump (7) and control system (12), wherein, between supercharge pump (7) and control system (12), be disposed with solenoid directional control valve (8), safety valve (9), pressure regulator valve (10), between pressure regulator valve (10) and control system (12), be also provided with filtrator (11).
Described supercharge pump (7) is also provided with hand supercharging handle (70).
The course of work is: the pressurized air by control system (12) is after filtrator (11), by pressure regulator valve (10) voltage stabilizing to authorised pressure, pressure is read by tensimeter, pressurized air enters supercharge pump (7) through solenoid directional control valve (8), supercharge pump (7) is according to the magnitude relationship of air pressure, ratio output water under high pressure, exports to air drum test specimen through high-pressure stop valve (5).After test, the residual voltage in pressure piping is unloaded by high-pressure unloading valve (3).In addition,, owing to being also provided with safety valve (9) between supercharge pump (7) and control system (12), ensured that output pressure can not transfinite.By regulating driving gas pressure and flow, the output pressure of supercharge pump (7) can be realized accurate electrodeless output.
