Abstract
The utility model provides a high-efficiency clamping device for flow tests in spray rods. The device is characterized by mainly comprising a process header pipe, an adapter component and a joint. The adapter component is welded on the process header pipe. The joint is connected with the adapter component through a thread. When the device is used, the spray rod is inserted into the adapter component, and then is screwed by the joint. The high-efficiency clamping device for the flow tests in the spray rods has the advantages that: the operating state of a header pipe is simulated, and the flow tests in all the spray rods on the header pipe are finished on the process header pipe, so that a total flow and distribution remain unchanged after all the spray rods are welded to the header pipe, flow test processes for single spray rods are eliminated, the adjustment amount of each spray rod in the test of the header pipe is decreased, production efficiency is greatly improved, and a production cycle is shortened; in addition, each spray rod of the process header pipe is connected with a hose through a quick reloading joint, and then is connected with an oil recovery device of a tester, so that the conventional outdated manual binding method is changed, clamping time is saved, and test efficiency is improved.
Description
Technical field
The utility model relates to the device for testing flow of spray boom.
Background technology
Afterburning fuel manifold is under the aeroengine thrust augmentation state, atomizes well to indoor the supply according to quantity of afterbunring, and the fuel oil that is evenly distributed makes it and air mixed, fully burning.Afterburning house steward's fuel delivery is on the high side, or on the low side, perhaps skewness, all directly shadow noon after-burner performance and job stability.For fuel oil is scattered equably, require the flow basically identical of similar spray boom in the after-burner, the difference in flow between each nozzle opening should be in the scope of detail of design regulation.Because the nozzle opening geometric configuration of same apertures, the difference of surface quality all can influence the flow of subtle bar, therefore, after the machining, spray boom also will carry out flow test, with the flow and the fuel oil skewness of inspection spray boom.
The flow test of spray boom adopted the way of single-piece test originally always, because single house steward's spray boom numbers of poles is many, and twenties at least; Sixties at most; Therefore, the flow test workload of spray boom is huge, all is the restriction house steward bottleneck operation of delivery cycle all the time.
Summary of the invention
The purpose of the utility model is to provide a kind of clamping device of once accomplishing a plurality of spray boom flow tests.
The utility model provides a kind of flow test of spray boom efficiently to use clamping device, it is characterized in that: mainly comprise technology house steward, adaptor assembly and joint, adaptor assembly is welded on the technology house steward, and joint is connected with adaptor assembly with screw thread.During use spray boom is inserted in the adaptor assembly, reusable connector is screwed.
The flow test of spray boom efficiently that the utility model provides is used clamping device, and its technology house steward can comprise pipeloop and oil inlet pipe, and pipeloop is connected through threeway with oil inlet pipe, realizes that oil circuit connects.
The flow test of spray boom efficiently that the utility model provides is used clamping device; Its adaptor assembly can comprise breakout box and sleeve, breakout box and technology house steward welding, and breakout box is connected with sleeve with sliding fit; Be lined with O-ring seal between breakout box and the sleeve, sleeve cooperates through between centers crack, hole with spray boom.
The flow test of spray boom efficiently that the utility model provides is used clamping device, and the quantity that can be welded with breakout box on its technology house steward is equal to engine has quantity in fact, and No. one time clamping is accomplished multinomial flow test.
The flow test of spray boom efficiently that the utility model provides is used clamping device, and its advantage is: simulation house steward duty, in the flow test of accomplishing all spray boom single poles on the house steward on the technology house steward; Thereby guarantee that total flow and distribution remain unchanged after all spray booms are soldered to house steward; Like this, cancel the flow test technology of the single bar of disputing, reduced the adjustment amount of each spray boom when house steward tests; Greatly improve production efficiency, saved the production cycle; In addition, each spray boom of technology house steward is connected with the oil-collecting device of exerciser after connecting flexible pipe through the joint that changes the outfit fast, has changed the primitive method of original manual binding, has saved the clamping time, has improved test efficiency.
Description of drawings
Fig. 1 be efficiently the spray boom flow test with the structural representation of clamping device;
Fig. 2 be efficiently the spray boom flow test with the partial enlarged drawing of clamping device.
Embodiment
Embodiment 1
The spray boom flow test is used clamping device efficiently; Its structure is as illustrated in fig. 1 and 2; Two circles are welded on the technology house steward 1 with its breakout box 2.1 inside and outside comprising technology house steward 1, adaptor assembly 2 and 3,60 adaptor assemblies of joint 2 minutes, and joint 3 usefulness screw threads are connected with adaptor assembly 2; Technology house steward comprises pipeloop and oil inlet pipe, and pipeloop is connected with the oil inlet pipe oil circuit through threeway; Adaptor assembly comprises breakout box 2.1 and sleeve 2.2, and breakout box 2.1 is connected with sleeve 2.2 with sliding fit, is lined with O-ring seal 2.3 between breakout box 2.1 and the sleeve 2.2, and sleeve 2.2 cooperates through between centers crack, hole with spray boom 4.
During flow test, the process duct assembly is contained on the exerciser, oil-feed connects mouth and the exerciser outlet is joined; At first adjust fuel pressure during flow test to setting; Test at twice, battalion's time 40 spray booms in test outer ring, next tests 20 spray booms of inner ring; Twice test flow sum equals total flow, and test period is 180 seconds.Need measure the spray boom total flow during test and calculate the flow distribution unevenness of spray boom.
