Bubble coalescence motor and method thereof
Technical field
The invention belongs to technical field of engines, relate in particular to a kind of bubble coalescence motor and method thereof.
Background technique
Existing internal-combustion piston engine uses fossil fuel more, and the High Temperature High Pressure that produces during by burning promotes piston and does work.Because in the course of the work, the temperature in its cylinder is higher, so require the material use exotic material (mostly being metallic material) of engine cylinder-body and be equipped with cooling water channel to cool off at engine interior.This just makes that the whole build of motor is big, Heavy Weight.In the conventional engine working procedure, relate to the conversion of heat energy to mechanical energy, heat greatly outwards scatters and disappears by cylinder body and water channel, has caused very big energy loss, has reduced the thermal efficiency.Intermetallic mechanical friction has reduced the mechanical efficiency of motor.Conventional engine uses fossil fuel, can give off certain harmful gas after the burning, and human body and environment are worked the mischief.In combustion process, the burning of fossil fuel is comparatively violent, can cause bigger noise.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of bubble coalescence motor and method thereof are provided.
The bubble coalescence motor comprises sign change ultrasonic pulse generator, negative pressure ultrasound wave impulse generator, liquid level sensor, liquid injection port, relief opening, piston, output shaft, bubble coalescence chamber, position transducer, engine cylinder-body, cylinder; Bottom, bubble coalescence chamber is provided with sign change ultrasonic pulse generator, negative pressure ultrasound wave impulse generator, the indoor liquid working substance that is filled with of bubble coalescence, bubble coalescence chamber one side inwall is provided with liquid level sensor, another sidewall of bubble coalescence chamber is provided with liquid injection port, top, bubble coalescence chamber is provided with cylinder, cylinder sidewall is provided with relief opening, position transducer, is provided with piston in the cylinder, and piston links to each other with output shaft.
The bubble coalescence starting method is: under the effect of sign change ultrasonic pulse generator, make can in the inner pressure field that produces sign change of the liquid working substance of bubble coalescence chamber, under the effect of negative pressure ultrasound wave impulse generator, liquid working substance is inner because cavitation effect can make liquid working substance inside produce little bubble, grow up gradually, the bubbling polymerization that closes on forms bigger bubble, when the position transducer of piston through being provided with on the cylinder sidewall, trigger the sign change ultrasonic pulse generator, make the negative sense pulsed ultrasonic wave that sends change forward into, the small bubble of liquid working substance inside are under the effect of the forward ultrasonic pulse that the sign change ultrasonic pulse generator sends, the bubble boundary layer can lose to stablize and make bubble break, be accompanied by the rising of temperature, emit internal gas, the thrust that produces promotes piston, in the piston stroking upward process, promote output shaft by connecting rod, when piston process relief opening, gas in the cylinder is discharged, pressure recovery normal state in the cylinder, descent of piston, form a circulation, go round and begin again, realize the bubble coalescence starting method.
Conventional engine uses fossil fuel, temperature and pressure in its working procedure is all very high, this just requires the material high-temperature-resistant high-pressure-resistant of engine cylinder-body, so present motor adopts metallic material to cast more, this just makes the big Heavy Weight of motor volume, the manufacture cost height, simultaneously for can be with the temperature maintenance of motor a temperature that relatively is fit to, engine interior need be provided with cooling water channel and cool off.And the present invention is owing to adopt the bubble coalescence method for generation, in the work engineering, temperature and pressure in the cylinder is lower, thereby can give up motor manufacture method commonly used, can use light materials such as highstrenghtpiston to cast, this just makes manufacture cost reduce, and manufacturing time shortens, the motor miniaturization and.The cooling water channel of engine interior can not cast yet, thereby significantly reduces the difficulty of making.
Conventional engine uses fossil fuel, and the tail gas that the burning back produces can produce very big influence to environment.And in the process of burning, energy greatly can distribute with the form of heat, causes very big energy loss.Operating temperature of the present invention is low, and dispersed heat is few, so its thermal efficiency is higher.And circulation of its inner formation of motor of the present invention, the high-temperature vapor that relief opening is discharged refills liquid cylinder through after the condensation, can not give off tail gas environment is polluted.And because this process is comparatively gentle, significantly the noise that brings of reduction work prolongs operating life simultaneously.

Embodiment
As shown in Figure 1, the bubble coalescence motor comprises sign change ultrasonic pulse generator 1, negative pressure ultrasound wave impulse generator 2, liquid level sensor 3, liquid injection port 4, relief opening 5, piston 6, output shaft 7, bubble coalescence chamber 8, position transducer 9, engine cylinder-body 10, cylinder 11; 8 bottoms, bubble coalescence chamber are provided with sign change ultrasonic pulse generator 1, negative pressure ultrasound wave impulse generator 2, be filled with liquid working substance in the bubble coalescence chamber 8, bubble coalescence chamber 8 one side inwalls are provided with liquid level sensor 3, bubble coalescence chamber 8 another sidewalls are provided with liquid injection port 4, be provided with piston 6 in the bubble poly-21, piston 6 links to each other with output shaft 7.
The present invention's piston is set to up-set type.Be more convenient for like this starting.Simultaneously, because cylinder temperature is lower, can select the material of main part of plastics as piston.In order to reduce the friction between piston and casing wall, use many annular rubber rings to seal.With the outside of this sealing rubber ring bound rubber, can freely load and unload, to maintain easily as piston.The present invention is provided with liquid level sensor, and when liquid working substance dropped to the fixed position, liquid working substance was injected to the bubble coalescence chamber by liquid injection port, stops when the liquid level of liquid working substance reaches original position.
The bubble coalescence starting method is: under the effect of sign change ultrasonic pulse generator 1, make can in the inner pressure field that produces sign change of the liquid working substance of bubble coalescence chamber 8, under the effect of negative pressure ultrasound wave impulse generator 2, liquid working substance is inner because cavitation effect can make liquid working substance inside produce little bubble, grow up gradually, the bubbling polymerization that closes on forms bigger bubble, the position transducer 9 that on piston 6 process cylinders 11 sidewalls, is provided with, trigger sign change ultrasonic pulse generator 1, make the negative sense pulsed ultrasonic wave that sends change forward into, the small bubble of liquid working substance inside are under the effect of the forward ultrasonic pulse that sign change ultrasonic pulse generator 1 sends, the bubble boundary layer can lose to stablize and make bubble break, be accompanied by the rising of temperature, emit internal gas, the thrust that produces promotes piston 6, in piston 6 up processes, promote output shaft 7 by connecting rod, when piston 6 process relief openings 5, gas in the cylinder 11 is discharged, pressure recovery normal state in the cylinder 11, piston piston 6 is descending, form a circulation, go round and begin again, realize the bubble coalescence starting method.
The present invention is descending by driven by motor at first, when the position transducer of piston through being provided with on the cylinder sidewall, triggers the sign change ultrasonic pulse generator, thus ato unit.When the motor gas in the jar normally promoted the piston acting, motor cut out.
