There are handle, pressurized handgrip, the handle front end is equipped with shut-off valve.Shut-off valve makes laminate section and detection part connection for obstructing
System, anti-major structure laminate section check valve leakage.
Fast joint, model M20 × 1.5 of the fast joint are installed on the left of the air pump.The fast joint upper end peace
Equipped with pressure gauge.
The commutation handle and pressure-relief valve of pressure and vacuum are installed on the right side of the air pump.Wherein, commutation handle is pulling out
When be converted to pressure, promote when be converted to vacuum；Pressure-relief valve, which rotates clockwise, to close, and rotate counterclockwise openable.It is described
Rear portion is equipped with safety valve on the right side of air pump, is connected with soft air-guide pipe on rear side of the safety valve, the soft air-guide pipe rear end is connected with
Air filter, the air filter upper end are connected with aircraft engine lubricating oil pressure sensor.
A kind of test method of motor oil pressure test device, specifically includes the following steps:
It pressurizes step 1: removing pressurized handgrip by hand to system, it is soft that the gas after pressurization passes sequentially through safety valve, air guide
Pipe, air filter will have the air delivery of certain pressure into aircraft engine lubricating oil pressure sensor, be test engine lubricating oil system
Pressure is made in controlling.
Step 2: directly reading the output pressure of air pump by pressure gauge；
It is made step 3: the output pressure value of air pump when reaching near the pressure for needing to detect, first closes shut-off valve barrier
The connection of laminate section and detection part, then it is set to by the pressure that trimming hand wheel will test part the pressure value of needs.
Step 4: can will there is the gas of pressure to be discharged in atmosphere in system by pressure-relief valve after detection.If plus
When pressure is higher than aircraft engine lubricating oil pressure sensor permissible value, high pressure gas can be discharged in atmosphere by safety valve, be kept away
Exempt from aircraft engine lubricating oil pressure sensor degradation.
In conclusion the present invention is will to be changed to be transmitted by air as pressure as pressure transmission medium by liquid originally to be situated between
Matter overcomes stoste dynamic formula lubricating oil pressure setter since the pollution of oil liquid causes aircraft engine oil system contaminated
Defect.The present invention provides pressure source by hand pressurized handgrip, will be clean after filtering and have the air of certain pressure as Jie
Matter passes to pressure in motor oil pressure sensor, provides the pressure of needs for test engine lubricating oil pressure sensor
Source avoids and is surveying since gas can be precipitated after testing equipment with removing automatically from oil liquid after the end of the test
Engine oil system is contaminated when examination.
The beneficial effects of the present invention are:
The present invention is to be changed to be overcome by air as pressure transmission medium as pressure transmission medium by liquid originally
Stoste dynamic formula lubricating oil pressure setter is solved since the pollution of oil liquid leads to the contaminated defect of aircraft engine oil system
Hydrodynamic pressure setter periodic cleaning gives environment bring pollution problem, has that light-weight, be simple and safe to use can
It leans on, energy conservation and environmental protection, solves the problems, such as that stoste mobile pressure setter be easy to cause aircraft engine oil system to pollute.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is perspective view of the invention.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below it is right
The present invention is further described.
As shown in Figure 1, a kind of motor oil pressure test device, including air pump 13,13 front end of air pump are equipped with
Trimming hand wheel 6, trimming hand wheel 6 can carry out rotating clockwise pressurization adjusting and rotating pressure-decreasing counterclockwise is adjusted.On the air pump 13
Portion front end, upper end are separately installed with handle 4, pressurized handgrip 3, and 4 front end of handle is equipped with shut-off valve 5.Shut-off valve 5 is for hindering
It is contacted every making laminate section with detection part, anti-major structure laminate section check valve leakage.
Fast joint 2, model M20 × 1.5 of the fast joint 2 are installed on the left of the air pump 13.On the fast joint 2
