Description

Pressure-loaded pilot system
Technical field
The utility model is used for fluid pressure load test application field, and in particular to a kind of fluid pressure load test system System can be used for the ultralow pressure pressure-loaded test of a variety of media.
Background technique
For applying pressure to testpieces, certification test part bears the ability of pressure for pressure-loaded test.Pressure-loaded examination The performance of check system directly determines that can pressure-loaded test be completed, and can the ability that testpieces bears pressure accurately be examined Core.
A variety of loading methods such as hydraulic pressure, oil pressure, air pressure can be used in pressure-loaded test, for the reality of real simulation testpieces Border applying working condition is typically chosen the medium that testpieces uses in actual work and carries out pressure-loaded test.Such as radiator is carried out Pressure-loaded test can radiate object according to the actual inside of different radiators to select loaded medium, and such as: water radiator uses Hydraulic pressure pressure-loaded, diesel oil radiator is using diesel pressure load etc..
Different pressures loaded medium is incompatible, if the testpieces of different medium uses incorrect pressure and adds Carry medium and carry out inner pressure test, not only have an impact to test result, can also performance to testpieces and construction cause to get rusty, corrode Deng damage, testpieces is caused to cancel.If testpieces type kind is more, working media is different, it is necessary to opposite using more sets It answers the pressure-loaded pilot system of medium to be tested, considerably increases experimentation cost.
In addition, part test part demand fluid pressure load test require on-load pressure it is very low, pressure regulation spectrum compared with Greatly, electrodeless adjustment is realized from tens pas to tens megapascal.But due to the inherent characteristic of pump group in hydraulic system, reached once opening To 2~3MPa, system is made to cannot achieve the particular/special requirement of ultralow pressure adjusting.Even if in addition the decompression members such as pressure reducing valve, are limited by The architectural characteristic of decompression member itself, system are generally also only able to achieve the pressure regulating power of minimum 0.1MPa, cause certain super Low pressure test (LPT) demand is unable to get satisfaction.
Utility model content
Pressure-loaded pilot system described in the utility model utilizes air pressure adjustment pressure in such a way that hydraulic and air pressure combines Power range is larger, the characteristics of ultralow pressure is adjusted can be achieved, and as the pressure regulating part point of pressure-loaded system, it is added with hydraulic Loading system combines.And by the way of multi-path choice access, pressure-loaded system is allow to be compatible with a variety of different Jie simultaneously Matter carries out pressure-loaded test.When test, it is only necessary to according to the demand of subjects, select corresponding test(ing) medium.
Technical solution used by this method is: a kind of pressure-loaded pilot system, by pneumatic pressurizing system, booster jar group It is formed with fluid pressure line, pneumatic pressurizing system is used to provide pressure limit lower limit ultralow pressure source to load test system, increases Pressure tank is mainly used for the incompatible test liquid medium of store various types, while can be realized good sealing, in Pneumatic Pressure When pressed gas is input in booster jar by system, the pressure of pressed gas is passed into test liquid medium, makes gas Body pressure is converted into fluid pressure, and guarantees that pressed gas and test are not revealed with liquid medium, while booster jar also acts as surely The effect of pressure guarantees that the two is connected to by the loading accuracy of system, fluid pressure line for connecting booster jar group and testpieces.
The booster jar group includes air inlet shut-off valve, filler shut-off valve, booster jar, booster jar pack support, high pressure Jie Matter outlet shutoff valve, liquidometer, air inlet shut-off valve are mounted on the air inlet of booster jar, pass through gas pipeline and pressure regulator valve Gas vent connection, air inlet are used for the input of high pressure gas, and filler shut-off valve is mounted on the filler of booster jar, test It is added in booster jar with medium by filler, liquidometer is mounted on the lateral of booster jar, can be observed in real time by liquidometer The test liquid level of medium in the booster jar, high-pressure medium outlet are connect by pipeline with testpieces, and test is logical with medium It crosses the outlet to be connected to medium in testpieces, transfer the pressure in testpieces, high-pressure medium outlet shutoff valve is mounted on pressurization The high-pressure medium exit of tank is connect by fluid pressure line with testpieces.
The application method of the pressure-loaded pilot system, system carry out pressure-loaded examination using certain road medium therein When testing, the air inlet shut-off valve of other booster jars, filler shut-off valve and high-pressure medium outlet shutoff valve are all closed first, Certain the road booster jar liquidometer used is observed, whether the liquid level of checkout facility medium meets the requirements, if lower than requiring Highly, the filler shut-off valve of the road booster jar is opened, test medium is added in booster jar by filler;If high In requiring height, the high-pressure medium outlet shutoff valve of the road booster jar is opened into angle appropriate, uses the test in booster jar Medium slowly flows out, and until the liquid level of test medium meets the requirements, high-pressure medium outlet shutoff valve is passed through hydraulic tube Road is connect with testpieces, closes filler shut-off valve, is opened air inlet shut-off valve and high-pressure medium outlet shutoff valve, is made at system In trystate, gas source is opened at this time, adjusts the setting pressure of pressure regulator valve, while observing the indicating value of pressure sensor, until pressure The indicating value of force snesor reaches test requirements document pressure and stabilization, system worked well, when system stalls, closes gas source, will High-pressure medium outlet shutoff valve is closed, and filler shut-off valve is slowly opened angle appropriate, serves as filler shut-off valve Exhaust valve, the pressure slow release in booster jar are 0, are then shut off filler shut-off valve, system stalls.
Compared with prior art, the application has following marked improvement: pressure-loaded test described in the utility model system It is larger using air pressure adjustment pressure limit, the characteristics of ultralow pressure adjusting, work can be achieved by the way of system is combined using hydraulic and air pressure For the pressure regulating part point of pressure-loaded system, hydraulic loaded is converted to by air pressure-loading.And using multi-path choice access Mode allows pressure-loaded system to be compatible with a variety of different mediums simultaneously and carries out pressure-loaded test.This system is simple and easy to do, Design cost is low, can be widely applied to various pressure-loaded tests application.
Pressure-loaded pilot system described in the utility model is real using the characteristic and function for commonly using hydraulic and pneumatic component The adjusting control of 0.05MPa may be implemented in multimedium compatibility, the function of ultralow pressure pressure regulation pressure testing of existing system, minimum pressure System, can be compatible with a variety of different types of test(ing) mediums simultaneously.This system is simple and easy to do, and design cost is low, can be widely applied to Various pressure-loadeds test application.
