Abstract

A device for cleaning aviation jet engines based on robots and high-pressure pulsed water-jet comprises a pulse conversion device, a fixed seat, a jetting head, and an amplitude transformer. The device is characterized in that the pulse conversion device is connected to the end part of the jetting head to form a whole through the fixed seat; one end of the amplitude transformer is installed inside the central cavity of the jetting head; and the other end of the amplitude transformer is connected to the amplitude transformer through a fixing piece. High-pressure water is boosted by a booster pump, flows through the central cavity of the jetting head and is cavitated by the oscillation of the amplitude transformer, and then jet from a nozzle of the jetting head at a high speed to form pulsing jet and cavitation jet to scatter, peel, erode, and clean coatings and claddings. In addition, the use cost of the device is extremely low.

Description

Based on robot high-voltage pulse water jet jet aerial engine flushing apparatus

Technical field

The utility model relates to a kind of cleaning device, relates in particular to a kind of based on robot high-voltage pulse water jet jet aerial engine flushing apparatus.

Background technology

Present stage domestic air mail, space industry the repairing of parts such as blade, burner inner liner of jet aerial engine in, its coating, carbon distribution removes that main what adopt is lathe grinding, artificial polishing, methods such as chemical reagent immersion corrosion are removed.Use this type of technology to remove the shortcoming of coating: the easy damaged part base solid causes part to scrap, and artificial grinding efficiency is low, and processing cost is high, and chemical reagent is harmful to the operator, contaminated environment.Removing at the face coat of these parts of American-European developed country is to realize with ultra-high pressure water fluid jet, and the pressure of water jet is more than 300MPa.So this method is because hypertonia is very strict to the requirement of water, water must soften and could use through the high-purity filtration.Nozzle requires very hard wear resistant, and nozzle generally all is to adopt sapphire or diamond to make, and the service life of each nozzle, so use cost was very high at 100-150 hours.

Summary of the invention

It is a kind of based on robot high-voltage pulse water jet jet aerial engine flushing apparatus that the purpose of the utility model is to provide; This device is intended to improve being coated with in the jet aerial engine maintenance process of Aeronautics and Astronautics field, coating is removed operation; Make its technology more science, more efficient, to the damage of part reduce, energy-conservation, use cost is low, creates higher economic benefit.What present technique adopted is: mixed the efficient water jet that forms high-voltage pulse jet and high pressure cavitation jet coexistence by high-power ultrasonics and water under high pressure.High-power ultrasonics is transformed into high-frequency mechanical vibration through horn makes high-pressure water jet be transformed into the hf and hv pulse water jet, has formed the water hammer effect with huge transient energy, and this effect has strengthened abilities such as the fragmentation, erosion of jet greatly.High-power ultrasonics has very strong cavitation to glassware for drinking water; Make and produce a large amount of air bubble formation cavitation jets in the water jet a fluid stream, air bubble goes out the microjet and the shock wave that produce breaking of rigid solid near surface with the high-speed water jet beam object that is impacted is had very high peak value hitting power and very strong cavitation erosion effect.Just because of two kinds of water jet actings in conjunction when hydraulic pressure is lower than the pressure of 60MPa, also can remove efficiently hardly be coated with, coating, have broken efficiently, peel off, erosion, cleaning performance.

The utility model is realized like this; It comprises pulses switch device, holder, sprayer body, horn; It is characterized in that the pulses switch device is integrally formed through the end that holder connects sprayer body; Be connected with an end of horn in the cavitation chamber, center of sprayer body, the other end of horn inserts the pulses switch device through fixture.Water under high pressure accepts through the cavitation chamber, sprayer body center of flowing through after the booster pump supercharging that the nozzle from sprayer body penetrates at a high speed after vibration and the cavitation of horn, form pulsing jet and cavitation jet realization to be coated with, the fragmentation of coating, peel off, erosion and cleaning.

The technique effect of the utility model is: with existing ultra-high pressure water fluid jet compared with techniques; Reach same cleaning performance present technique water jet pressure and be no more than 60MPa; So because the low requirement to water and nozzle of water jets pressure is relative also very low, the water of use is common running water (city's water), the nozzle manufacturing materials is common stainless steel; Cheap, so use cost is very low.A time technology also is in the blank stage at home, has vast market prospect.

The specific embodiment

As shown in Figure 1; The utility model is realized like this; Pulses switch device 14 is integrally formed through the end that holder 10 connects sprayer body 3, is connected with an end of horn 11 in the cavitation chamber, center 4 of sprayer body 3, and the other end of horn 11 inserts pulses switch device 14 through fixture 13.During use, the water under high pressure that is pressurized to about 50MPa through the high pressure pumping plant gets into sprayer body 3 from the water inlet pipe 1 through sealing nut 2 sealings.Taper fairlead 7 concentrates on the center to water a bit, makes the kinetic energy of water and pressure moment change big.The impulse wave that the pulse passages through which vital energy circulates red switch changing device 14 that the while pulse generating unit sends sends; Be delivered to horn 11 through fixture 13; Make horn 11 front end faces produce the higher-order of oscillation; This higher-order of oscillation acts in the water, makes water on the basis of high pressure, have high speed kinetic energy (high-voltage pulse jet and cavitation jet); The water jet of mixed pulses vertically hits on cated workpiece from spraying at a high speed through nozzle nut 6 nozzles 5 fixing and sealing.Make the coating moment on the workpiece peel off, and do not damage workpiece from workpiece.For preventing that the situation of leaking from appearring in the coupling part, said sprayer body 3 inwalls also have lining 8, and this installs most sealing by 12 sealings of rubber " O " RunddichtringO, favorable sealing property, the situation that can not occur leaking.
