2, turn working procedure and the principle of energy machine
(1) when high-pressure medium can convert mechanical energy to
Turn while can machine making motor, high-pressure medium can be converted into mechanical energy, its RQ1 position cavity volume arranges suction port, and QR7-RQ12 position cavity volume sets out gas port.
During work, suppose that rotor 5 is rotated counterclockwise, in the time converting high-pressure medium to mechanical energy, RQ1 is full of high-pressure medium, turns to successively RQ2-RQ6, and cavity volume increases gradually, and air pressure reduces gradually.For certain blade, its right side RQ1 air pressure is greater than left side RQ2 air pressure, therefore can promote blade rotates counterclockwise, the like the poor promotion that is all under pressure of each blade be rotated counterclockwise, this makes each blade of left side in Fig. 1 all be subject to the promotion of the difference force of air pressure, promotes to turn and can externally do work by machine.Meanwhile, the expansion ratio that turns energy machine can design, and for the source of the gas of certain pressure, flow, can obtain best changing effect.According to thermodynamic principle, from RQ1 and RQ6, it is an isentropic process, being accompanied by volume increases, the temperature of medium must reduce, thereby pressurized gas part water vapour when arriving RQ6 of RQ1 part is liquefied, the energy of the high pressure so not only making full use of, also makes the energy of gas liquefaction discharge the mechanical energy that changes into promotion blade.From RQ7 to RQ12 deflation course, the air pressure of this process is all a bit larger tham the air pressure that turns energy machine Outdoor Space, and the gas in cavity volume is put into Outdoor Space, till RQ12, a cyclic process finishes.
(2) when mechanical energy converts high-pressure medium energy to
Turn when can machine making pump and using, mechanical energy is converted into high-pressure medium energy, at this moment RQ1, RQ2-RQ6 position arrange intakeport, and RQ12 position can arrange the air outlet of high-pressure medium, and air outlet is an one-way valve, and outside is pressurized gas storagies.
During work, set rotor 5 and be rotated counterclockwise, air-breathing from environment at RQ1, RQ2-RQ6 position, turn to intakeport sealing behind RQ6 position, under the effect of external force, rotor 5 is rotated counterclockwise, and compressed media progressively dwindles the volume of cavity volume, and this process is the compression process of constant entropy, until pressure is greater than the pressure of pressurized gas outside air outlet in cavity volume, at this moment one-way valve opens, while turning to RQ12, pressurized gas have been carried.A circulation finishes.
(3) can machine for turning of motor
Set: shell 1 is motionless, transcapsidation 3 rotor 5 blade 4 axle 6 rotating in same directions, sense of rotation is counterclockwise.Cavity volume RQ1 is outer in locations of high pressure, along with RQ1 rotates to RQ2.RQ3.RQ4.RQ5.RQ6. direction, media expansion at this moment, medium to turn can machine blade 4 works done, high-pressure medium can convert mechanical energy to, by axle 6, exports; When reaching RQ6 position, Exhaust Open, the high-pressure medium having done work (still higher than atmospheric pressure) by relief opening rapidly discharged to air, the barometric pressure that plunges of the pressure medium in RQ6; Air inlet open after a while, it in air-inlet cavity, is inflammable gas (inflammable gas refers to the mixed gas of air and diesel oil, gasoline, rock gas or other fuel), the pressure of suction port is greater than the now pressure of cavity volume, the gas flow cavity volume of suction port, and original burnt gas continues to be discharged in atmosphere by relief opening in cavity volume, this action should complete in the position of RQ7, RQ8, RQ9; While arriving RQ9 position, suction port and relief opening are closed simultaneously, RQ9-RQ10-RQ11 is the process of compressing inflammable gas, can reduce the output torque of axle 6, to the some position igniting mounted points between RQ11 and RQ12, fire the inflammable gas in cavity volume, inflammable gas is burning or blast rapidly, temperature, pressure raise rapidly, are again then high-pressure medium works done.
For gas medium, because gas has compressible performance, turn and can machine can utilize the compression of gas or expansion absorption or the energy discharging and mechanical energy to change.Owing to turning, can there be an inflation process and a compression process by machine, get as required which process and coordinate again different inlet and outlet mouths can realize the various uses such as pump, motor, motor.For liquid medium, the compressibility of medium itself is very little, and compression and expansion process can make medium pressurization or externally acting, coordinates different liquid entering holes and liquid port to make motor and pump.The engineering goods of different purposes, all can adopt and turn and can identical principle and the structure of machine realize.
3, turn industrial applicibility and the technical prospect of energy machine
Of the present utility model turning can machine be calculated and practice through theoretical, and verified its feasibility and reliability, particularly its transformation efficiency, far away higher than existing energy conversion device.
(1) for motor pneumatic, turning can machine:
Suppose to turn the volume of certain cavity volume of energy machine before arriving air outlet, the business of the volume having sealed divided by this cavity volume has just departed from suction port is called expansion ratio.For the particular medium with certain pressure, different expansion ratios can obtain the transformation efficiency that different high-pressure mediums can change into mechanical energy.Turn can machine expansion ratio be programmable, according to various parameters, can adopt optimized expansion ratio.Do turning that motor uses and can obtain larger expansion ratio by machine, and the high-pressure medium in expanding can almost can all change into mechanical energy.For majority, with water vapour, make the motor of medium, by the calculating of thermodynamic equation, high-pressure steam high-pressure medium temperature under larger expansion ratio declines larger, water vapour is emitted vaporization heat and is directly changed into damp steam or water under cryogenic high pressure, the efficiency that can change into mechanical energy is high, also can reduce the amount of condensed steam simultaneously.Compare steam turbine and with impact force, steamer is done work, turn and can with pressure, blade be done work by machine, conversion efficiency is high, and no matter watt level can be used.
(2) can machine for pneumatic the turning of pump
