Abstract
The utility model discloses a kind of hydraulic cleaning testing equipment, including oil inlet pipe, oil return line, hydraulic cleaning testing stand, and the cleaning testing equipment is pressurized equipment, cleaning and pressure test for plane hydraulic system.The utility model solve the problems, such as stoste pressure cleaning testing equipment existing for plane hydraulic system pipeline sealing propertytest accuracy rate it is low, discharge airplane Hydraulic Tube excess oil when low efficiency, put it is not clean, the accuracy of breakdown judge and the efficiency of troubleshooting are substantially increased, and improves excess oil discharge efficiency.Belong to the invention of aviation hydraulic system technology class.
Description
Technical field
The utility model belongs to aviation hydraulic system technical field, is related to a kind of hydraulic cleaning testing equipment.
Background technique
Plane hydraulic system after installation is complete, need to be cleaned with hydraulic cleaning testing equipment.During cleaning,
It needs to carry out fluid pressure line pressure test, it is therefore an objective to the leakproofness of test macro pipeline.Existing hydraulic cleaning testing equipment be by
Testing stand is connected to the oil inlet pipe and oil return line of aircraft by two hoses.When pressure test, from testing stand to hydraulic system
Pipeline is filled with authorized pressure value, is then shut off testing stand, and whether decline the sealing for judging pipeline by pressure in hydraulic system
Property.During carrying out pipeline pressure test, due to the defect of testing stand itself, often result in close to plane hydraulic system pipeline
The erroneous judgement of envelope property failure and system pipeline discharge excess oil are not smooth.Therefore, airplane hydraulic pressure existing for existing hydraulic cleaning testing equipment
System pipeline sealing propertytest accuracy rate is low, discharge airplane Hydraulic Tube excess oil when low efficiency, put not clean problem.
Utility model content
Purpose of utility model: being to provide a kind of can temporarily disconnect when hydraulic system cleans pressure resistance with fluid pressure line on aircraft
Hydraulic cleaning testing equipment.The testing equipment can exclude pressure in the hydraulic system pipeline as caused by testing stand and decline, from
And the accuracy and efficiency of plane hydraulic system pipeline leakproofness breakdown judge is greatly improved；Due also to discharge airplane Hydraulic Tube
In excess oil when there is no the resistance of finished product inside testing stand, pipeline, excess oil discharge is very unimpeded.
Technical solution: a kind of hydraulic cleaning testing equipment, including oil inlet pipe, oil return line, hydraulic cleaning test are provided
Platform, the cleaning testing equipment are pressurized equipment；
The in-line are as follows: be communicated to the oiler of airborne hydraulic systems by check valve from cleaning testing equipment；
Oil return line are as follows: be communicated to cleaning test after contacting pressure gauge and shut-off valve from the oil return opening of airborne hydraulic systems and set
It is standby；
The check valve is merely capable of being connected from cleaning testing equipment to airborne hydraulic systems；
The shut-off valve is switch valve, for realizing the on-off of oil return line.
Further, it is also communicated with branch in oil inlet pipe, switch valve, energy when switch valve is opened is provided on the road Qie Zhi
It is enough that oil liquid is shunted.
Further, it is also communicated with branch in oil return line, switch valve, energy when switch valve is opened is provided on the road Qie Zhi
It is enough that oil liquid is shunted.
Further, it is hose that oil pipe used is connected in the oil inlet pipe and oil return line.
The utility model has the advantages that can exclude the pressure as caused by cleaning testing stand using this hydraulic cleaning testing equipment and decline, from
And the accuracy of hydraulic system pipeline leakproofness breakdown judge and the efficiency of troubleshooting is greatly improved；Due also to discharge aircraft liquid
There is no the resistance of finished product, pipeline inside testing stand in pressure pipe road when excess oil, excess oil discharge is very unimpeded.
Detailed description of the invention
Fig. 1 is the hydraulic cleaning experiment work loop structure schematic illustration of the utility model；
Wherein: 1- check valve, 2- in-line branch, 3- shut-off valve, 4- oil return line branch, 5- airborne hydraulic systems, 6- are clear
Wash testing equipment, 7- pressure gauge.
Specific embodiment
A kind of hydraulic cleaning testing equipment, including in-line, oil return line, cleaning testing equipment are provided in conjunction with Fig. 1, it is described clear
Washing testing equipment is pressurized equipment；
The in-line are as follows: be communicated to the oiler of airborne hydraulic systems by check valve from cleaning testing equipment；
Oil return line are as follows: be communicated to cleaning test after contacting pressure gauge and shut-off valve from the oil return opening of airborne hydraulic systems and set
It is standby；
The check valve is merely capable of being connected from cleaning testing equipment to airborne hydraulic systems；
The shut-off valve is switch valve, for realizing the on-off of oil return line.
Further, it is also communicated with branch in oil inlet pipe, switch valve, energy when switch valve is opened is provided on the road Qie Zhi
It is enough that oil liquid is shunted.
Further, it is also communicated with branch in oil return line, switch valve, energy when switch valve is opened is provided on the road Qie Zhi
It is enough that oil liquid is shunted.
Further, it is hose that oil pipe used is connected in the oil inlet pipe and oil return line.
