The test equipment of hydraulic pressure in electromotor deaeration capability, influent pressure and cylinder sleeveTechnical field
This utility model is related to a kind of test equipment of hydraulic pressure in electromotor deaeration capability, influent pressure and cylinder sleeve, for sending outMotivation install evaluation when test engine off gas system evaluation and water inflow of the engine pressure and cylinder sleeve in hydraulic pressure test data receiptsCollection.
Background technology
Technical staff, when IQA experiment is done by OEM producer, needs to connect observing tube into the engine water outlet installed in OEMIn pipeline, the bubble in off gas system is observed by observing tube, the deaeration capability of off gas system is judged with this.At present, electromotorIQA test uses common glass tubing, and time-consuming laborious, the frequent rupture of installing/dismounting, the proportion of goods damageds are big.In process of the testThe situation of glass tracheal rupture occurred, there is larger security risk.According further to the actually used degasification bore of OEM, testPersonnel need to carry the glass tubing that 10～60mm does not wait, and are inconvenient.
Electromotor needs when installing evaluation to test hydraulic pressure in intake pressure and cylinder sleeve of engine, tests currently without suitableInstrument, often cannot test.
Content of the invention
The purpose of this utility model is that the test providing hydraulic pressure in a kind of electromotor deaeration capability, influent pressure and cylinder sleeve setsStandby, there is the distinguishing feature being easy to dismount, versatility is good, test efficiency is high, safety coefficient is high.
The technical solution of the utility model：Hydraulic pressure in electromotor deaeration capability of the present utility model, influent pressure and cylinder sleeveTest equipment includes observing tube, installs rustless steel observation window pipe in the outside of observing tube, and observing tube is centrally mounted at rustless steel and seesExamine in window pipe, there is a female thread at the two ends of rustless steel observation window pipe, the female thread of one end installs in first the blocking of hexagonal through hole and theOne adaptor, the first adaptor connects ball valve, and the other end of ball valve connects the first pagoda joint；Rustless steel observation window pipe anotherEnd female thread is installed hexagonal through hole in second and is blocked and the second adaptor, the first port of the second adaptor connecting tee joint,The second port of three way cock connects the second pagoda joint, the test adaptor of the 3rd port installation of three way cock；FirstIn interior hexagonal through hole blocking and second, the blocking of hexagonal through hole is pressed on the two ends of observing tube respectively.
There is the first rubber seal between the first hexagonal blocking and observing tube, between the second hexagonal blocking and observing tubeThere is the second rubber seal.
In the outside of observing tube, rustless steel observation window pipe, 4 observation windows of rustless steel observation window Guan Shangshe, observation window position are installedIn the center of rustless steel observation window tube body and circumferentially symmetrical.
Advantage of the present utility model：Two ends of the present utility model adopt pagoda joint, can quickly dismount in degasification pipeline.Ball valve is in order to control the turnover of engine cooling water.During test, pagoda joint carries out degasification energy from engine warm air pipe line diversionPower is tested, and can meet more than 90% testing requirement, need not carry multiple calibers.Safety glass, tool are installed inside observation window pipeThere is higher safety coefficient.
Safety glass pipe outside nesting rustless steel observation window pipe, is substantially improved safety coefficient, reduces risk of rupture, and protection is surveyedThe safety of examination personnel.Middle 4 observation windows are located at center and the circumferentially symmetrical branch of body.Tester can be by observingBubble situation in window pipe sight glass pipe, evaluates off gas system deaeration capability with this.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2, Fig. 3, the test equipment of hydraulic pressure in electromotor deaeration capability of the present utility model, influent pressure and cylinder sleeveIncluding observing tube 1, in the outside of observing tube 1, rustless steel observation window pipe 11 is installed, observing tube 1 is centrally mounted at rustless steel observation windowIn pipe 11, there is a female thread at the two ends of rustless steel observation window pipe 11, and the female thread of one end installs in first hexagonal through hole blocking 5 and theOne adaptor 6, the first adaptor 6 connects ball valve 2, and the other end of ball valve 2 connects the first pagoda joint 3；Rustless steel observation window pipe11 other end female thread installs the blocking 7 of hexagonal through hole and the second adaptor 8, the second adaptor 8 connecting tee joint in second12 first port, the second port of three way cock 12 connects the second pagoda joint 4, the 3rd port installation of three way cock 12Test adaptor 13；In hexagonal through hole blocking 5 and second in first, hexagonal through hole blocking 7 is pressed on the two of observing tube 1 respectivelyEnd.
Blocking in the first hexagonal has the first rubber seal 9 between 5 and observing tube 1, blocks 6 and observing tube in the second hexagonalThere is the second rubber seal 10 between 1.
In the outside of observing tube 1, rustless steel observation window pipe 11 is installed, rustless steel observation window pipe 11 sets 4 observation window 11a,Observation window 11a is positioned at the center of rustless steel observation window pipe 11 body and circumferentially symmetrical.
When this utility model uses, original for electromotor warm braw outlet pipe is split into two sections, by the second pagoda joint andFirst pagoda joint is connected respectively to the pipeline two ends being split, and equipment is connected in warm braw outlet pipeline.During connection equipment,Current must be that the second pagoda joint flows into, and the first pagoda joint flows out.In electromotor, evaluation degasification test requirements document operating mode is installedUnder, you can observe that electromotor off gas system eliminates the situation of bubble by observation window.
Test adaptor joint test pressure transducer.By pressure transducer cut-in pressure measuring apparatus, can readThis presses force value.When ball valve is opened, measuring point pressure value is similar to water inflow of the engine pressure, and now degasification test feelings observed by observation windowCondition.When ball valve is closed, this measuring point pressure is equal to hydraulic pressure in cylinder sleeve.
According to test environment, the second port of three way cock mutually can be exchanged with the 3rd port.
