Description
Technical field
The utility model is related to aircraft hose test engineering device technique fields, are specially a kind of hose gas permeation testing stand.
Background technology
Aircraft finished product hose (mainly includes the light-duty polytetrafluoroethylene (PTFE) straight peen-straight peen hose of 21MPa flared types, 21MPa
Flared type heavy type polytetrafluoroethylene (PTFE) straight peen-straight peen hose, 2MPa flared types hydrogenated butyronitrile straight peen-straight peen hose) be
Aircraft can work normally essential part, and therefore, the experiment to this hose is very necessary.When hose works,
It is as the instrument for transporting gas or liquid, once extremely serious consequence will be generated by occurring leakage in transportational process,
So leak test is carried out to hose.
Utility model content
It, can be to hose into promoting the circulation of qi in view of the above-mentioned problems, the utility model provides a kind of hose gas permeation testing stand
Body leak test.
Its technical solution is such：A kind of hose gas permeation testing stand, including shell, water tank, compress cell, institute
Stating compress cell includes pressure sensor, servo valve, servo-drive cylinder, supercharging device, and the servo-drive cylinder is led to using oil pipe
The oil return interface and repairing interface crossed on the shell are connected with hydraulic pressure pump group, and the supercharging device is supplied using tracheae by gas
It is connected to mouth with source of the gas, it is characterised in that：The supercharging device is tested soft with being installed inside the water tank by appendix
The connector connection of pipe, the tested hose top are equipped with gas collection cap, and the gas collection cap bottom is installed on the water tank
Under interior water level, liquid level sensor and suction interface, the suction interface and vacuum pump are installed at the top of the gas collection cap
Connection, the compress cell, the liquid level sensor, the vacuum pump and controller electricly connect.
It is further characterized by：
The gas collection cap passes through guide rod and the cage connection；
The tank top is equipped with explosion-proof protecting cover, and the explosion-proof protecting cover is electricly connected with controller.
After with such a structure, by pressurizeing to hose, leaked out by liquid level sensor detection from hose
Air cause the variable quantity of water level in gas collection cap to calculate the mean permeability of hose, so as to carry out leak test；
Testing stand is operated by controller, easy to operate；In addition, the use of explosion-proof protecting cover can increase testing stand safety
Property.
Description of the drawings
Fig. 1 is test platform structure figure（Omit front shell and explosion-proof protecting cover）；
Fig. 2 is gas collection cap structure chart；
Fig. 3 is test platform structure total figure.
Specific embodiment
A kind of hose gas permeation testing stand as shown in Figure 1, Figure 3, including shell, water tank 1, compress cell, water tank 1
Top is equipped with explosion-proof protecting cover 14, and explosion-proof protecting cover 14 is electricly connected with controller, only when explosion-proof protecting cover 14 is closed,
Testing stand could work, and compress cell includes pressure sensor, servo valve 2, servo-drive cylinder 3, supercharging device 4, servo
Driving cylinder 3 is connected using oil pipe by the oil return interface 5 on shell and repairing interface 6 with hydraulic pressure pump group, and supercharging device 4 utilizes gas
Pipe is connected by gas supply port 7 with source of the gas, and supercharging device 4 is tested soft for installing by appendix and 1 inside of water tank
The connector 8 of pipe connects, and is tested directly over hose and is equipped with gas collection cap 9, as shown in Fig. 2, 9 lower length of gas collection cap is more than
Upper length, gas collection cap 9 are installed on by guide rod 10 and cage connection, 9 bottom of gas collection cap in water tank 1 under water level,
9 top of gas collection cap is equipped with liquid level sensor 11 and suction interface 12, and suction interface 12 is connected with vacuum pump 13, supercharging
Unit, liquid level sensor 11, vacuum pump 13 are electricly connected with controller.
When carrying out gas permeation experiment, hose one end is installed on connector 8, the other end is blocked, and adjusts gas collection cap 9
Make below its bottom immersed in liquid level and be located at directly over hose, unlatching vacuum pump 13 takes the air in gas collection cap away
So that the liquid level inside gas collection cap rises, pressurizeed by compress cell to hose inflation, so as to pass through compressed gas
Body applies hose the operating pressure of 21MPa, is kept for 15 minutes, and the gas of leaking hose causes after being collected by gas collection cap 9
9 inside liquid level of gas collection cap declines, and liquid level at this time is recorded by liquid level sensor 11, then pressurize 5 minutes, measures 5 minutes
Liquid level inside gas collection cap 9 afterwards, the percolation ratio of hose can be calculated by liquid level difference twice, this process artificially installs
It after hose, vacuumizes, be pressurized, the operation of level sensing can be operated by controller, very convenient.
More than, it is only the preferable specific embodiment of the utility model, but the scope of protection of the utility model is not limited to
In this, any people for being familiar with the technology is in the technical scope disclosed by the utility model, the change or replacement that can readily occur in,
It should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with claim
Subject to protection domain.
