Description

Translation revolving compressor mechanical

Technical field

The technology of the present invention relates to compressor and fluid pump field, it is specifically related to a kind of novel translation revolving compressor mechanical, both various gas can have been compressed, as refrigeration, compressor or as air force compressor, it is possible to use in various fluid pump fields.

Background technology

In positive displacement compressor, the compressor as plane motion type has two types, i.e. rolling rotor compressor and screw compressor. in compressor with rolling rotor, rotor is off configuration in the cylinder, when rotor is under the drive driving axle, when cylinder axis rotates, the outer surface of rotor is affixed on the inner surface of cylinder and slides, slide plate head is close on the outer surface of rotor under spring force, thus, the outer surface of rotor, a swept volume is constituted between inner surface and the slide plate of cylinder, this swept volume then increases along with the increase of angle of rotor, when swept volume reaches maximum, complete the process of an air-breathing, at this moment the rotated circle of rotor, namely corner is 360 ��, rotor continues to rotate, this swept volume then reduces along with the increase of corner, at this moment the gas in swept volume is compressed, when the pressure of swept volume gas reaches the required pressure of system, gas is discharged by the air bleeding valve being arranged on cylinder, complete an air-breathing, compression and exhaust work circulation. when gas in swept volume is compressed, often in order to reduce gas from compression chamber to the leakage of suction muffler, slide plate head must be close to the outer surface of rotor and act on certain pressure, not only result in slide plate head so on the one hand and produce bigger fretting wear with rotor outer surface, add energy loss, also make the poor reliability of machine simultaneously. what is more important, every two turns of compressor with rolling rotor just can complete a cycle of operation, and efficiency is low, and volume is big. screw compressor is then dependent on arrestment mechanism and the gyration of main shaft is changed into the Moving plate plane motion around quiet dish, a pair working chamber of outmost turns opens gradually along with the rotation of main shaft, gas enters working chamber by the air entry being arranged on outside quiet dish, the gas entered increases along with the increase of corner, until reaching maximum, eventually form the crescent working chamber of closing, complete a breathing process, along with main shaft continues to rotate, Moving plate just looks like a piston, gas in working chamber is elapsed to center from outer ring, meanwhile working chamber then can be gradually reduced, gas receives compression, finally discharged by centre bore.Although the gyration of main shaft is changed into the Moving plate plane motion around quiet dish by screw compressor, reduce speed of related movement, decrease fretting wear, but the sealing of working chamber gas is dependent on what the precision of profile processing ensured, processing technique requires extremely strict, and manufacturing cost is high. What is more important, the air vent of screw compressor must be opened in certain fixing position, center, define fixing compression ratio, requirement service condition is stable, but actually system pressure and admission pressure are often what constantly change, therefore the problem of overcompression and insufficient compression is apparent and is difficult to avoid that, not only causes energy loss, and it would furthermore be possible to cause operating safety failure.
