Abstract
The invention relates to a device for testing an automobile air compressor, in particular to a device for supplying cooling water to the air compressor and detecting the integrity of a cooling water channel of the air compressor in a thermal shock or overspeed overload test which is simulated by the automobile air compressor on the basis of the real running condition of an automobile engine and has a worse working condition. The cold water tank and the hot water tank are both closed containers and are connected with a gas collecting tank with a pressure detection device. When the air compressor is used for carrying out thermal shock or overspeed overload tests, once a cooling water channel in a cylinder cover of the air compressor is damaged, gas can enter a water circulation system because the exhaust pressure of the air compressor is generally higher, and the pressure rise can be observed through a pressure detection device arranged on a gas collection tank in a closed cooling water circulation supply device, so that the problem can be found in time and the test is stopped.
Description
Technical field
The present invention relates to a kind of automobile air compressor test device, be specifically related to a kind of automobile air compressorIn the more severe thermal shock of the operating mode simulating based on the true ruuning situation of automobile engine orIn hypervelocity overload test, air compressor machine is carried out to the inspection of cooling water supply and air compressor machine water channel integritySurvey device.
Background technology
Compared with other universal air compressor machines, automobile air compressor is as big-and-middle-sized truck and passenger carThe critical component of brakes, focus on its reliability, more because this is directly connected to automobileSecurity. For the requirement that detects its reliability, in industry, conventionally adopt one to be called thermal shock examinationThe method of testing, the even more severe hypervelocity overload test of operating mode. Above two kinds of tests are simpleGround is said, is all variable speed, discharge load in the time of setting, and by the longer test periodRear observation analysis air compressor machine inner case. Automobile air compressor due to itself be without drive, unlubricated,Non-refrigerated head, will be equipped with dynamical element, transmission system, profit to it so detect experimental rigThe lubricating oil circulatory system, cooling water feed system, external condition control device and electric-control system etc. OneAs in situation, oil circulation system, cooling water feed system are all open type loop structure, rightIn the time carrying out the performance tests such as air compressors, specific power, generally do not have because the time is shorterProblem. But for thermal shock test, hypervelocity overload test, the test period all hundreds of onThousand hours, the probability that air compressor machine goes wrong increased, in the time that air compressor cooling water road goes wrong,Open type cooling water feed system can't detect this situation, and test can be proceeded, and has just causedHuman and material resources and waste of time, therefore open type cooling water feed system often just seems and not too closesSuitable.
Summary of the invention
The object of this invention is to provide a kind of automobile air compressor test device, ensure that air compressor machine is doingCooling water when thermal shock or the test of hypervelocity over burdening is supplied with, the integrity to air compressor machine water channel simultaneouslyMonitor in real time.
For achieving the above object, the present invention has adopted following technical scheme: a kind of Air Compressor Test dressPut, comprise a water cooling pond, a hot-tub, water cooling pond and hot-tub are by pipeline and transfer valveBe connected with the internal water circulation line of air compressor machine, water pump is installed in pipeline. Water cooling pond and hot-tubBe hermetically sealed container, water cooling pond and hot-tub and a gas collection with pressure-detecting deviceTank is connected.
Technique effect of the present invention is: when stamping machine is carrying out thermal shock or hypervelocity overload testTime, there is breakage once air compressor cylinder cover internal cooling water channel, due to air compressor machine pressure at expulsion oneAs higher, gas can enter water circulation system, now by supplying with dress at closed cooling water circulationPut the pressure-detecting device of installing on gas collection tank and can be observed the rising of pressure, so justCan pinpoint the problems in time and stop test.

Detailed description of the invention
Shown in Fig. 1, a kind of automobile air compressor test device, comprises a water cooling pond 5,A hot-tub 17, water cooling pond 5 and hot-tub 17 is by pipeline and transfer valve and air compressor machine 23Internal water circulation line is connected, and water pump 19 is installed in pipeline. Water cooling pond 5 and hot-tub 17 are equalFor hermetically sealed container, water cooling pond 5 and hot-tub 17 and the gas with pressure-detecting deviceCollecting tank 14 is connected. Described gas-collecting pipe 14 is made for stainless steel, gas collection tank 14Be positioned at water cooling pond 5 and hot-tub 17 tops, gas collection tank 14 bottoms by pipeline respectively at coldPond 5 is connected with the top of hot-tub 17, and gas collection tank 14 tops are provided with Pressure gauge 13, normalClose magnetic valve 11, safety valve 10 and an air inlet pipe, described air inlet pipe is provided with pressure-reducing valve 9 HesNormally open solenoid valve 8. Described water cooling pond 5 is stainless steel closed container, and water cooling pond 5 is provided with temperatureDegree sensor 7, water cooling pond 5 inside are provided with cooling coil 6, the delivery port of water cooling pond 5 and backwaterMouth is arranged on basin bottom, and the delivery port of cooling coil 6 and water return outlet stretch out from water cooling pond 5 sidesBe connected with ice model tank 28. Described hot-tub 17 is stainless steel closed container, on hot-tub, arrangesA temperature sensor 16, hot-tub 17 inside are provided with electric heater 15, the going out of hot-tub 17The mouth of a river and water return outlet are arranged on hot-tub 17 bottoms, and the water return pipeline of hot-tub 17 is provided with oneAir-cooled radiator 21.
Air compressor machine is before carrying out thermal shock or hypervelocity overload test, due to water cooling pond 5 and hot waterPond 17 is all airtight, so for guarantee system does not produce negative pressure in pond in the time supplying water, firstAir inlet pipe on gas collection tank 14 is communicated with source of the gas, and gas reduces pressure and arrives through pressure-reducing valve 9Then 0.1Mpa enters gas collection tank 14, so just intrasystem air pressure will be able to be stabilized in0.1MPa, now can start test. Carry out in process in test, adjusted in concert Pneumatic three-way valve 18,25 circulations that can realize hot water or cold water are supplied with, and should be noted that Pneumatic three-way valve 18,25 is necessaryAdjusted in concert (simultaneously connecting hot-tub or water cooling pond) is to avoid hot water or cold water to mix. According to oftenThe specific requirement of inferior test regulates hand adjustment choke valve 20,24 just can reach the flow and the pressure that needValue. Because air compressor machine pressure at expulsion is generally higher, once air compressor cylinder cover internal cooling water channel occursBreakage, gas just can enter water circulation system and finally converge in gas collection tank 14 along pipeline,Now can observe gas collection tank 14 internal gas pressures by Pressure gauge 13 and raise, stop at once examinationTest, dismantle and check air compressor machine. When there are special circumstances, for example, when operating personnel's negligence does not haveCan observe in time pressure rising time, now in gas collection tank, 14 pressure can continue to raise,In the time that pressure reaches certain numerical value, just normally closed solenoid valve 11 can be opened release automatically, if now normalClose the malfunctioning object that can also realize by safety valve 10 release of magnetic valve 11 sensor-based systems.
