Description
Technical field
The utility model relates to a kind of cartridge cleaning device, particularly a kind of high efficiency composition cleaning device that is applicable to the system oil filter filter cores such as aircraft lubricating oil, hydraulic oil and fuel oil.
Background technology
The filter of oil on aircraft is widely used in the systems such as lubricating oil, hydraulic oil and fuel oil of aircraft, and along with the increase of flight time, the pollution meeting of oil filter filter core is more and more serious, cleans, otherwise will affect the normal work of system to tackling filter core after certain hour.For military aircraft, in order to shorten the maintaining time, improve field work condition, improve maintenance quality, operating efficiency and guarantee benefit, the cleaning of filter core often requires dismantle and carry out scene and clean at the land used scene that makes of oil filter filter core, this just requires corresponding cleaning device can aircraft oil filter core be realized efficiently and being cleaned, and simultaneously for the ease of at line using, also requires this device to have the features such as volume is little, conveniently moving, good economy performance.
For the cleaning problem of military aircraft oil filter filter core, a line attendant adopts the method for " manual cleaning " conventionally." manual cleaning " refers to that attendant uses hairbrush to clean oil filter filter core in kerosene (or gasoline) bucket, this method had both been damaged attendant's skin, waste again kerosene, and what is more important cleaning performance is not good, cleaning efficiency is lower, even can cause the secondary pollution of aircraft oil filter filter core.In the last few years, the one line unit of maintenance of military aircraft starts to be equipped with ultrasonic cleaning equipment, this cleaning device adopts single-frequency ultrasonic wave, although the cleaning performance of this " ultrasonic cleaning " " manual cleaning " has had lifting significantly, but the cleaning frequency is longer, scavenging period is long 5～6 hours, short 2～3 hours, Support overlong time, affects the serviceability rate of aircraft and turnout again.And existing oil is filtered cartridge cleaning device in the market, the large-scale cleaning device based on industrial flow-line or batch cleaning mostly, such device cleaning performance is better, but complex structure, bulky, a line that is not suitable for aircraft is safeguarded, is especially not suitable in the wild or carries out in mobile operating the cleaning of aircraft oil filter filter core.
Utility model content
The technical problems to be solved in the utility model is that a kind of aircraft oil that is suitable for using in military aircraft one line maintenance process of invention is filtered cartridge cleaning device, it can adopt various cleaning method to realize the high efficiency composition of aircraft oil filter filter core is cleaned, overcome the problem that in prior art, " manual cleaning " method cleaning performance is poor, cleaning efficiency is low, the problem that " ultrasonic cleaning " method cleaning frequency is long, and existing Large Oil filter cartridge cleaning device cannot carry out the problem of the high-efficiency washing of aircraft oil filter filter core in military aircraft one line or wild environment.
The utility model proposes a kind of aircraft oil filter cartridge cleaning device, specifically comprise: spray assembly, backwash assembly, megasonic cleaning module, hydraulic power unit, installation and transmission component, control system; It is characterized in that:
Spray assembly, by block valve, spray nozzle and form; Spray assembly for spraying cleaning, spraying cleaning can be large by the size of aircraft oil filter core outside, adhesive force is not that very strong dirt and impurity washes down from cartridge surface.
Backwash assembly, is comprised of block valve, pressure-reducing valve, back flushing nozzle; Backwash assembly is for backwash, backwash is from filter core internal feed cleaning fluid, part can be entered to the darker impurity of aircraft oil filter filter core and clean out, due to the flow direction of cleaning fluid, the flow through opposite direction of filter core of working solution during with normal work, is therefore called backwash.During backwash, note controlling by pressure-reducing valve in backwash assembly the pressure of cleaning fluid, by flow valve, control the flow of cleaning fluid, otherwise can destroy the structure that aircraft oil is filtered filter core when excessive when pressure and flow, cause unnecessary loss.
Megasonic cleaning module, is comprised of supersonic generator, transducer array and rinse bath; Megasonic cleaning module is used for carrying out Ultrasonic Cleaning.
Hydraulic power unit, is comprised of oil return circuit, fuel tank, oil feeding line, and described oil return circuit comprises block valve, the filter of oil return oil, and described oil feeding line comprises hydraulic pump, flow valve, the filter of fuel feeding oil, pressure-reducing valve, block valve;
Install and transmission component, mount pad, belt, motor, consist of, described mount pad comprises upper end cover, fixed bar, bottom end cover, liquid pipeline connector, swivel, and motor is connected by belt with swivel;
Control system is connected by circuit with spraying between assembly, backwash assembly, megasonic cleaning module, hydraulic power unit, installation and transmission component respectively;
Spray between each part of assembly, backwash assembly, hydraulic power unit, oil feeding line and spraying between assembly, backwash assembly, rinse bath, and between rinse bath and oil return circuit, all by pipeline, connect;
Described transducer array adopts the ultrasonic signal of three kinds of different frequency scopes to drive by supersonic generator.Experiment showed, when adopting single-frequency ultrasonic signal to drive transducer, easily on the surface of rinse bath, form standing wave, make the sound field skewness in rinse bath, affect the uniformity of cleaning performance.The ultrasonic frequency of using is higher, penetrates effect better, but the cavitation of Ultrasonic Cleaning declines; And the ultrasonic frequency of using is lower, the cavitation of Ultrasonic Cleaning is better, but penetrate effect, declines.The uniformity distributing in order to improve sound field, and the cavitation while guaranteeing aircraft oil filter filter element cleaning and penetrate effect, and then improve the effect of Ultrasonic Cleaning, therefore adopt the ultrasonic signal of three kinds of different frequency scopes to drive transducer.
