Description
Technical field
The present invention relates to surge or the pneumatic power machine, particularly rotor fluid machinery displacement-variable device.
Background technique
Current all kinds of fluid rotary displacement-variable device motion modes have: the mode of spiral motion mode, gear gear motion mode and eccentric wheel rotation, and these a few type games modes have various pluses and minuses, but its pluses and minuses are relative.
Fluid machinery is widely used machinery in industrial and agricultural production; and obtained sufficient development; in the middle of the process of science and technology development; reality produce in to the minimizing of energy consumption and the protection requirement of environment; all make technology and the economic requirement of convection cell machinery more and more higher; therefore, people constantly carry out perfect on existing mechanical mechanism to the aspects such as concrete structure design, processing technology and material of part, further to improve its every economic and technical norms.
Variable capacity internal-combustion engine, compressor, pump, motor and thus Xing bear other is as variant as its operating mode of the fluid machineries such as measuring apparatus, and each has become independently technical field voluntarily, yet, their main actuator is all volume class mechanism, and their main actuator has the mechanism that the generation cycle changes the function of closed cavity volume.The breakthrough that the rotor type fluid mechanical mechanism is realized, its some good characteristic had attracts people to create various rotor variable volume class machinery, and replacing the reciprocal transfiguration machinery of low speed with high-speed rotary transfiguration favourable turn tool is the design direction that meets modern machines.Common rotary volume-variable machinery comprises vane type oil pump or motor displacement-variable device, gear type pump or motor displacement-variable device, eccentric rotation-type displacement-variable device (single-acting blade-type, sliding vane or rub mechanism), roots-type etc.
Vane pump, according to the difference of its effect number of times, can be divided into two kinds of single-acting and double-actions.The characteristics of single acting vane pump are: rotor often circled suction, oil extraction each once, the characteristics of double-acting vane pump are: rotor often circled suction, each secondary of oil extraction.Double-acting vane pump is compared with single acting vane pump, and its discharge uniformity is good, and the suffered radial hydraulic pressure of rotor body is in a basic balance, and double-acting vane pump is generally metering pump, and single acting vane pump is generally variable displacement pump.The characteristics of vane pump are: compact structure, working pressure is higher, flow pulsation is little, stable working, noise is little, volume is little, lightweight, life-span is than the long bearing long service life, good endurance, volumetric efficiency is higher, working pressure is higher, the shortcoming of vane pump is: oil absorption is not so good, pollution to fluid is also more responsive, blade is easily killed, functional reliability is poor, structure is more complicated, manufacture process requirement is higher, speed adjustable range is little, maximum speed is lower, because blade throws away power, the impact of the factor such as speed of oil absorption and wearing and tearing, the rotating speed of pump can not be too large, also should not be too little, if rotating speed is too high, because its speed of oil absorption is too fast, can produce cavitation, inhale on the contrary not oil-feed, or oil suction is discontinuous, when rotating speed hangs down, because of centrifugal force inadequate, blade can not be close to stator inner surface, can not form the enclosed volume of good seal, thereby inhale, do not oil.Pump structure is than gear pump complexity, relatively, its noise is minimum for vane pump and gear pump, plunger pump, and it is many that machine industry is used, be all to adopt this pump mostly, vane pump is used widely in lathe, engineering machinery, boats and ships, die casting and metallurgy industry.The advantage of vane motor maximum is that volume is little, inertia is little, be active in one's movements, allow commutating frequency very high, even can in several milliseconds, commutate, but maximum weakness be leak larger, mechanical property is softer, can not work than under the slow-speed of revolution, speed adjustable range can not be very large, therefore be applicable to low torque, high rotating speed and less to the inertia requirement, mechanical property is required to not tight occasion, because variable vane motor structure is more complicated, relative movement part is many, leak larger, volumetric efficiency is low, mechanical property is soft and regulate the reason such as inconvenience, vane motor is generally all made quantitative, be that general vane motor is all the constant displacement hydraulic motor of double action.
Plunger pump is that displacement pump efficiency is high, can be for liquid gas two media, but to-and-fro motion has the defect of very large inertia, only limit low speed, the very complicated rapid wear of structure, single-cylinder pressure, flowed fluctuation is very large, plunger pump (oil hydraulic motor) is because the member-plunger and the cylinder inner bore that form pressurization working lumen are periphery, easy to process, easily obtain higher quality of fit, good airproof performance, therefore volumetric efficiency is high, working pressure is high, this pump just can change its flow very easily as long as change the stroke of plunger simultaneously, be easy to realize variable, therefore, plunger pump is applicable to high pressure, large flow, the occasion that powerful hydraulic system and flow need to be regulated.
The characteristics of gear pump are: cost is low, simple in structure, and volume is little, quality is light, good manufacturability, low price, suction capacity is strong, insensitive to oil contamination, and speed range is large, easy to maintenance, reliable operation, for low service system, to the working medium turbidity test, require low, radial effect power (leaking in existing) is arranged, and self-priming performance is good, and pressure pulsation is large; Its shortcoming is that entrap phenomenon is serious, radial imbalance force is large, leak greatly, flow pulsation is large, and noise is higher, the same with gear pump, gear type motor is because sealing is poor, and volumetric efficiency is lower, so the oil pressure of input can not be too high, thereby can not produce larger torque, and rotating speed and torque are all along with gear engagement situation and pulse.Gear type motor is multiplex in the hydraulic system of high rotating speed low torque, and gear pump generally can directly be made oil hydraulic motor and use, gear pump and gear type motor the two be to be used interchangeably.
Roots-type transfiguration machinery belongs to rotary volume-variable mechanism, the double leaf shape of two opposite direction synchronous rotaries or multi-leaf-shaped rotor are housed in mechanism, between rotor, all keep certain gap between rotor and shell inwall, the somewhat similar gear pump of action principle, and eccentric rotary transfiguration mode refers to that the eccentric rotation of rotor in cavity volume of installing realizes the mode of transfiguration.
Summary of the invention
The object of the present invention is to provide a kind of rotor fluid machinery displacement-variable device, compare with existing rotor variable volume mechanism, simple and reasonable for structure, discharge capacity is larger, and volumetric efficiency is higher, compact structure, turn round more steady, further reduce pressure pulsation and vibration, in conversion process of energy, energy loss is less, the transfiguration energy transfer mechanisms such as relative piston type, without to-and-fro motion, during running, epitrochanterian each particle is done same radius circular movement, can greatly reduce and overcome the required energy of inertia; Compare with vane type oil pump and motor, wear and tear less, the aneroid lock, as motor, without the consumption of compression negative work, starting torque is larger; With turbine, the mechanisms such as propeller cavitation compare, higher in slow-speed of revolution work limitation rate, relative sliding between cylinder internal rotor, stator can remove the solid pollutant accumulated in chamber by self-help cleaning, and leakage rate is less, and parts processing is simpler, therefore, the manufacturing cost is lower; According to the operating mode demand, change in design is easy, can reach by the configuration of adjusting simply axial and radial dimension and rotor set and center pivoted frame working speed, Operating torque and the traffic requirement in design under different operating modes.
