Abstract
The utility model relates to an oil discharging device for a dry-running test. The oil discharging device comprises an oil discharging joint, an oil discharging pipe, a solenoid valve, a flow meter, a flow regulating valve and an oil collector. The oil discharging joint is connected to an oil discharging position of a speed reducer, wherein the oil discharging position of the speed reducer can be arranged at an oil discharging port of the speed reducer, or arranged on a pipeline which connects an outlet of a lubricating oil pump of the speed reducer with a radiator outside the speed reducer; the other end of the oil discharging joint is orderly connected with the solenoid valve, the flow meter, the flow regulating valve and the oil collector through oil discharging pipes; and the oil collector is provided with an oil level mark. By the simple structure of the oil discharging device, lubricating oil leakage in a test run process of dry running is stimulated; the oil-out running test is carried out on the speed reducer; and the test requirements can be met.
Description
Technical field
The utility model relates to a kind of jettison gear, especially a kind of dried operation test jettison gear.
Background technique
According to civilian air worthiness regulation relevant regulations, the civil aviation retarder must possess 30 minutes running abilities after lubrication system loses efficacy, so that aircraft is taken emergency measures, the incidents that averts a calamity takes place.Therefore, the civil aviation retarder dried operation test that during developing, need be not less than 30 minutes is verified dry running ability.The program of draining the oil that in doing the operation test process, lost efficacy in order to simulation retarder lubrication system is very crucial; Control to retarder is drained the oil is wanted to reflect harsh situation in all conditions that possibly cause the lubrication system inefficacy; But it is too much to exceed this harsh situation; In order to avoid reduce the dried running time in the test, influence conclusion (of pressure testing).This is carrying out can reflecting the retarder dry running ability exactly when retarder is done operation test with regard to a kind of jettison gear of accurately and effectively controlling of needs.
Summary of the invention
The purpose of the utility model is to provide accurately a kind of and effectively controls jettison gear; This device is done operation test to the aviation retarder need simulate the requirement that lubrication system lost efficacy; Design a kind of jettison gear; Guarantee retarder in dried operation test process, promptly and accurately the contingent failure condition of simulation lubrication system is realized the examination to the retarder dry running ability.
The purpose of the utility model realizes through following technological scheme:
The utility model comprises oil extraction joint, oil exit pipe, solenoid valve, flowmeter, flow control valve and oil trap.Described oil extraction joint is connected the retarder position of draining the oil; The retarder position of draining the oil can be arranged on the fuel outlet place of retarder; The lubricating oil pump that also can be arranged on retarder exports on the pipeline that is connected with the outside radiator of retarder; The other end of described oil extraction joint connects solenoid valve, flowmeter, flow control valve and oil trap successively through oil exit pipe, and described oil trap has oil level mark.
Retarder is in doing the operation test process; At first test to steady state by normal test procedure; Open solenoid valve then and discharge lubricating oil, simulate the lubrication system failure condition simultaneously, regulate flow control valve; Control the speed of draining the oil, the lubricating oil of discharge is collected in the oil trap through the oil extraction pipeline and is measured the lubricating oil amount.Different retarders should be confirmed the speed of draining the oil according to the situation that contingent lubrication system lost efficacy, and generally the speed of draining the oil should be controlled at and reach the warning of main reducing gear lubricating oil low-voltage in 3 minutes, and this moment, retarder got into the operation test state of doing.
The utility model has realized in doing the running commissioning process that through simple structure the situation that the simulation lubricating oil is revealed does not have lubricating oil to retarder and does operation test, has satisfied test requirements document.The electromagnetic valve unlatching of draining the oil, identical through the dredge oil amount of the Flow-rate adjustment valve regulation amount of draining the oil when flowmeter show value and retarder possibly produce lubrication system and lost efficacy, collect the lubricating oil of emitting with the case of draining the oil with oil level mark, and metering lubricating oil amount.
Description of drawings
Fig. 1 is the connection schematic representation of the utility model.
Embodiment
As shown in Figure 1, device comprises oil extraction joint 1, oil exit pipe 2, solenoid valve 3, flowmeter 4, flow control valve 5 and oil trap 6.Oil extraction joint 1 is connected the retarder position of draining the oil; The retarder position of draining the oil can be arranged on the fuel outlet place of retarder; The lubricating oil pump that also can be arranged on retarder exports on the pipeline that is connected with the outside radiator of retarder; The other end of described oil extraction joint 1 connects solenoid valve 3, flowmeter 4, flow control valve 5 and oil trap 6 successively through oil exit pipe 2, and described oil trap 6 has oil level mark.
Claims (2)
