Description
Technical field
The present invention relates to the rotary vane type refrigeration compressor, is a kind of novel rotary type compressor, and this compression function effectively applies to the airborne evaporation circulating system.Belong to the airplane environment control technical field.
Background technique
Along with increasing of air environment, the heating power of electronic equipment constantly increases, and single air cycle refrigeration can not satisfy the overall needs of aircraft.Because mobility, the Stealth Fighter of aircraft improve constantly, ram-air has been subject to serious restriction as the heat sink use of environmental control system, and fuel oil becomes mainly heat sink.This new trend makes environmental control system more complicated, and the refrigeration form increases, and, be necessary in full machine scope, to carry out the unified management of heat energy.Integrated environment control/heat management system produces under this background just, and has obtained application on the advanced fighter abroad.
The refrigerating capacity overwhelming majority of the swap-in control system of advanced fighter is by evaporation circulating cooling system (VCS), according to the trend of fighter for Overseas Development, four generation machine thermal force be about 2 times of three generations's machine, fight five generations machine of future generation is expected to reach 100 kW, if following fighter is unmanned plane, required refrigerating capacity will be born by airborne evaporation circulating cooling system (VCS) fully.
Because the evaporation circulating cooling system reliability is relatively poor and refrigeration agent easily leaks not fine solution, the helicopter refrigeration system adopts air circulation refrigeration system more in early days.But along with the drawbacks such as the poor and refrigrant leakage of evaporation circulating cooling system reliability have obtained solution, add the plurality of advantages that it is compared with air circulation system, little such as high, the compensatory loss of the coefficient of performance, without motor bleed etc., therefore modern helicopter extensively adopts the evaporation circulating cooling system, and has the trend that replaces air circulation refrigeration system.
Displacement type compressor is by to the motion acting, to reduce the compression type volume, improves vapor tension and finishes compression function.Rotary compressor is prevailing to be usually to be called fixing sliding vane structure again " rolling piston compressor ", and slide plate is fixed, and only a slip is not rolled.Rotary blade type compressor is a kind of, a kind of novel rotary type compressor that volume less higher than sliding-vane compressor efficient.
Rotary blade type compressor is obtaining swift and violent development over nearly 10 years, and is simple in structure with it, volume is little, reliable operation, efficient high, demonstrates stronger market competitiveness in fields such as small-sized air compressor, used for automobile air conditioning compressors.The companies such as Japanese Matsushita Electric Industrial, Seiko essence machine, Jack Sai Er have all formed the ability of production in enormous quantities.And domestic rotary blade type compressor manufacturer is also less, and scale is also less, and structural type generally also is confined to type early.Facts have proved, rotary blade type compressor has its unique advantage in a lot of fields, be necessary to its further investigate, Devoting Major Efforts To Developing.
For high-revolving centrifugal compressor, its difficult point is the development of pneumatic bearing, and up to the present Russia does not break through this difficulty yet, therefore domesticly want to develop centrifugal compressor and also have very long stretch to walk, and there is eccentric force in other compressors.The rotary blade type compressor anti-overload ability is strong, turns scooter 10000rpm, becomes the first-selection of the airborne evaporation circulating system of domestic development.And existing rotary blade type compressor, because the restriction of self-characteristic, therefore the situation of large overload in the time of can not bearing airplane landing and taking-off only is widely used in the car air conditioner field, not in the aviation field large-scale application.
Summary of the invention
The purpose of this invention is to provide the rotary vane type refrigeration compressor under a kind of Chinese People's Anti-Japanese Military and Political College overload condition.
Comprise cylinder, rotor shaft, be installed on the rotor of rotor shaft.
Cylinder inner wall is similar to ovalize, and rotor and cylinder are concentric arrangement.Rotor and cylinder inner wall have two point of contact, and volume of cylinder is divided into two crescent-shaped spaces, and each crescent-shaped space is provided with air-breathing aperture and outlet valve.
It is characterized in that: spring also is installed in the above-mentioned slideway, and spring one end links to each other with the slideway bottom, and the other end links to each other with slide plate.
The maximum difference of rotary blade type compressor and sliding-vane compressor is that rotor and cylinder are concentric arrangement, the rotor complete equilibrium, so rotating speed can be very high, maximum speed can reach 9000r/ min.After improving rotating speed leakage is reduced, the size of machine and quality are reduced.Because slide plate is tilting, frictional force between slide plate upper end portion and cylinder inner wall and the frictional force between slide plate both sides and groove are reduced, therefore the efficient of rotary blade type compressor has also improved.
The present invention can be applicable to the airborne evaporation circulating system.Because in the process that aircraft aloft flies, compressor can bear sizable overload, in this case, because the effect of inertial force probably causes slide plate to break away from epitrochanterian slideway, thereby causes inefficacy.Therefore, between each slide plate and rotor, add shock mount, make spring bear in the worst case the overload of 9G.By spring rotor and slide plate are coupled together, can effectively prevent from being subject to the effect of inertial force and the inefficacy that causes at large overload condition lower compression machine.
