Description

High efficiency and multi-energy power machine

The utility model relates to a kind of high efficiency and multi-function motive power machine, belongs to the volume fluid machine field.

At the Chinese invention patent application number is in the patent application of (86106989), the composite gas motor of crossing the distribution of some valve is disclosed, this gas motor can be done low pressure engine and use, it 〉=1 gauge pressure gets final product work, but its piston reciprocates, its inertial force has and hinders in doing useful work, and the mechanical efficiency a during gauge pressure only is 30%.

The inertial force of part such as present known various gas-turbines etc., rotor etc. in addition help to do useful work, but gapped between epitrochanterian blade and the stator, and pressure release power consumption loss is big, can not do low pressure engine usefulness.

The Wankel engine of the U.S. has the complexity control of revolution, rotation, eccentrically mounted weight, and energy-saving effect is not obvious.

The purpose of this utility model, be to concentrate the advantage of positive displacement and scroll type fluid machinery, avoid deficiency of the prior art, propose a kind of high efficiency and multi-function motive power machine, making it all has very high mechanical efficiency under low pressure and high pressure, and is applicable to various energy resources and multiple use.

The utility model is realized by following measures: it utilizes the double rotor working principle in the Roots pump, weak elastic sealing device and fixing device on its double rotor, have been added, make its original double rotor in operation process, each other at the bottom of rotary-piston and the rotating cylinder, save the control that has revolution, rotation, eccentrically mounted weight etc. complicated in the single rotor piston engine, become no component and pressure difference more rational positive displacement turbine structure loss, all-sealed balanced rotation.On each rotor of power engine, respectively adorn the weak flexible seal arrangement of a cover, every suit seal arrangement is that one cover arc piston ring and a considerable amount of spring are formed, and a pair of double rotor is arranged on the power engine by a cover Sealing, so two cover seal arrangements are housed altogether.

Sealing is contained in the groove of rotor, the length of Sealing and the equal in length of rotor recesses.Sealing is on-stream not to be separated fully with rotor in order to make, and at the two ends of rotor recesses coupling is housed all, and its effect is to block Sealing and cluster spring all-in-one-piece fixing device.Sealing is close to stator inner wall by the spring of being adorned in the aperture of bottom, realizes gap-free sealed.Coupling is a concave shape, and the limit portion of its central closing and Sealing matches.Two end caps of power engine are pressed in arc piston bar in the arc groove of rotor end-face, and arc piston ring bottom is equipped with spring too, makes the arc piston ring be close to end cap, further realizes gap-free sealed.

As shown in drawings, when rotor (1) was vertical with the bottom plane of power engine, rotor (2) paralleled with the bottom plane of power engine; After 90 ° of the double rotor runnings, when rotor (2) is vertical with the bottom plane of power engine, rotor (1) parallels with the bottom plane of power engine, the positive displacement turbine structure of this all-sealed balanced rotation, make type of belt drive produce new meaning: when upper half part of rotor (1) was rotary-piston, rotor (2) then was a cylinder bottom; After 90 ° of the double rotor runnings, when rotor (2) upper half part was rotary-piston, rotor (1) then was a cylinder bottom ... circular work then makes this power engine possess the two-fold advantage of piston type and turbotype structure simultaneously so again and again.

The utility model, can be further perfect by following steps: Sealing (3) preferably be contained on the two-spool privileged site, so-called privileged site, be meant double rotor and stator, and double rotor between pairing position during minimum clearance, this position is exactly the position of opening rectangular recess on double rotor.Specific engagement location between the double rotor is to stretch out the pair of engaged gears that the axle head of end cap outside adorns by main shaft (11) to control, the shape size of pair of engaged gears, and assembling and adjusting method etc., just the same with known Roots pump.In the requirement to sealing is not under the situation of strictness especially, in certain occasion, can only add Sealing (3) on the double rotor, and needn't add arc piston ring (4), should try one's best littler but note the gap between double rotor two ends and the end cap this moment.How much elastic-friction power between Sealing and stator, the double rotor is by deciding of the rigidity of adjusting spring (8) and the number of springs of packing into.

The utility model compared with prior art, has simple in structurely, and cost of production is low, the advantage of good energy-conserving effect.With diameter of stator bore is that 116 millimeters high efficiency and multi-function motive power machine is an example: air consumption is 0.9 cubic metre of a per minute, and 0.4～0.5 gauge pressure can start, and 〉=1 gauge pressure gets final product work, and mechanical efficiency is 63%; When tolerance increase air pressure was increased to 3 gauge pressures, mechanical efficiency was 93%.Under the identical conditions, diameter of stator bore is big more, and double rotor strengthens thereupon, and it is obvious more that mechanical efficiency improves.

When this power engine was regarded vacuum pump and blower use, degree of vacuum and outlet pressure improved more than 10 times than known technology.

This power engine can use under low pressure and high pressure, and is applicable to various energy resources and realizes electrodeless variable-speed.Utilizing the fine and soft saddle and bridle a horse Γ of low pressure  malen  to narrow that (tip of a twig   male the taking off of the clear field  of ü      of expanding turned the billy goat  ⒌ chivalrous  plum of  division of a ci poem Feng of relaxing and rectified Gui  Job's tears wise to wash the eyebrow gully idle

The utility model is further described in conjunction with the accompanying drawings: Sealing (3) has 12 on power engine shown in the drawings, have 6 on each rotor, and the large-sized power machine also can be made the double seal structure.On each rotor, end face is equipped with 6 arc piston rings (4), if utilize arc piston ring (4) to replace coupling (7) to block Stamping Steel Ribbon (3), can save coupling (7) so, one times of a pair of arc piston ring lengthening is arranged this moment, and the quantity of arc piston ring reduces 2.Gap between the end flat of double rotor (1), (2) and the end cap (5), be to realize sealing by Sealing (4), sealing is realized by Sealing (3) between double rotor (1), (2) and the gap between double rotor (1), (2) and the stator (6).Sealing (3) and arc piston ring (4) by spring (8), are realized the elasticity between its stator, end cap, the double rotor is directly contacted.Sealing (3) is stuck in the groove (9) of rotor by coupling (7), makes Sealing (3) only do short distance in rotor recesses (9) and slides and can not separate with rotor.Hydrodynamic source enters effectively power machine inner chamber from import (10), promotes piston rotation work done, and reaction force acts is being on another rotor on the cylinder bottom, and in cycle operation, two rotors are piston and cylinder bottom each other.

Most preferred embodiment of the present utility model is this power engine as turbo machine in gas turbine engine, low-pressure water turbine, the gas turbine and compressor etc. when using, and obvious energy-saving effect is all arranged.Accompanying drawing is the three-dimensional cutaway view of high efficiency and multi-function motive power machine.
