Fig. 1 is the schematic representation of the gas compressor that provides of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of gas compressor that the utility model embodiment provides comprises the casing 1 of both ends open, and an end of casing 1 and first end cap 2 are tightly connected, and the other end of casing 1 and second end cap 3 are tightly connected;
Be equipped with a rotating shaft 4 that is positioned at casing on described first end cap 2 and second end cap 3, be installed with clutch shaft bearing 41 on first end cap 2, be installed with second bearing 42 on second end cap 3, the two ends of rotating shaft 4 are connected with second bearing 42 with clutch shaft bearing 41 respectively, thus the purpose that the two ends of realizing rotating shaft 4 are rotationally connected with first end cap 2 and second end cap 3 respectively;
Be installed with a rotor 5 in the described rotating shaft 4, offer the shock tube 6 of at least one axial setting along rotating shaft 4 on the rotor 5, shock tube 6 along the circumferential direction is evenly distributed on the rotor 5, and particularly, the quantity of shock tube 6 is 1 ~ 100;
Offer pressurized gas inlet 21 and the minimal pressure gas outlet 22 that can communicate with shock tube 6 on described first end cap 2, pressurized gas inlet 21 is used for pressurized gas are accelerated to the velocity of sound or ultrasound velocity;
Offer the pressurized gas outlet 31 of compressed back and the compressed preceding low-pressure gas entrance 32 that can communicate with shock tube 6 on described second end cap 3;
The outer periphery of described rotor 5 are installed with blade 7, offer on the casing 1 with blade 7 over against the propellant entrance 11 that arranges and propellant outlet 12.
The concrete working principle of the gas compressor that the utility model provides is as follows:
(1) the incident stage: propellant enters in the casing 1 from the gas access 11 that drives casing 1, propellant promotes blade 7 and rotates, blade 7 drives rotor 5 and rotates together, and after rotor 5 rotated, pressurized gas accelerated by pressurized gas inlet 21, spray into successively in the oscillator tube 6 on the rotor 5 with the velocity of sound or supersonic speed, wherein, propellant can be the sub-fraction of pressurized gas shunting, also can be other source of the gas, in addition, the rotation of rotor 4 also can drive by equipment such as motors;
(2) compression stage: the pressurized gas that are accelerated by pressurized gas inlet 21 are to low-pressure gas compressed action before compressed in the shock tube 6, because spraying into the gas of shock tube 6 from pressurized gas inlet 21 is velocities of sound or supersonic, so can produce shock wave during low-pressure gas when pressurized gas spray into before shock tube 6 runs into existed in the shock tube 6 compressed, low-pressure gas before compressed in the pressurized gas that shock wave sprays into just as an invisible piston cuts off and the shock tube 6, and low-pressure gas before compressed in the shock tube 6 compressed, the temperature and pressure of the compressed preceding low-pressure gas in the shock tube 6 is all raise, discharge by compressed back pressurized gas outlet 31 then; The pressurized gas that spray into from pressurized gas inlet 21 are because to low-pressure gases acting before compressed in the shock tube 6, self-energy is consumed, and stays in the oscillator tube 6 so become minimal pressure gas simultaneously;
(3) compressed preceding low-pressure gas injects the stage: stay the minimal pressure gas in the shock tube 6, rotation along with rotor 4, can be communicated with minimal pressure gas outlet 22 and compressed preceding low-pressure gas entrance 32, low-pressure gas enters in the shock tube 6 by low-pressure gas entrance 32 before compressed before compressed, minimal pressure gas in the shock tube 6 is ejected, minimal pressure gas is discharged by minimal pressure gas outlet 22, and compressed preceding low-pressure gas is stayed in the shock tube 6; Rotation along with rotor 5, shock tube 6 is communicated with pressurized gas inlet 21 and compressed back pressurized gas outlet 31, the compressed preceding low-pressure gas of staying in the shock tube 6 is compressed by the pressurized gas from pressurized gas inlet 21 incidents again, enters next circulation, and so forth circulation.
In sum, adopt the to-and-fro motion of piston to come directly gas to be compressed different with prior art, gas compressor of the present utility model adopts pressurized gas that low-pressure gas is compressed, and realizes the purpose of pressurized gas, and compression efficiency significantly improves.Wherein, the composition of pressurized gas and low-pressure gas can be identical, also can be different.
Further, also be provided with two sealing plugs 8 between described casing 1 and the rotor 5, the outlet 12 of propellant entrance 11 and propellant is between two sealing plugs 8, and sealing plug 8 is used for isolated high-voltage gas, propellant and compressed gas, guarantees the normal operation of system.
In addition, the utility model adopts propellant to enter in the casing 1 from propellant entrance 11, propellant promotes blade 7 and rotates, blade 7 drives rotor 5 and rotates together, therefore, rotating shaft 4 of the present utility model need not stretch out that casing 1 is outer to be connected with motor and to be rotated by motor driving, the sealability of casing 1 significantly improves, and has significantly reduced the amount of leakage of the interior pressurized gas of casing 1.Simultaneously, be connected with motor because rotating shaft 4 of the present utility model need not be stretched out outside the casing 1, therefore, reduced the volume of whole air wave refrigerating device, convenient transportation, installation and operation.
The above is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
