The invention discloses an interior volume ratio regulating mechanism for a single screw compressor. The interior volume ratio regulating mechanism comprises a machine enclosure, wherein a screw and an engagement pair consisting of two symmetrically arranged plane star wheels are mounted inside the machine enclosure; a slide valve assembly for regulating interior volume ratio is further mounted inside the machine enclosure; the slide valve assembly comprises a left piston cavity, a right piston cavity, an external sliding block and an internal sliding block, a left piston rod is mounted inside the left piston cavity, the left piston rod is connected with the external sliding block, a right piston rod is mounted inside the right piston cavity, the right piston rod is connected with the internal sliding block, the external sliding block is in sliding fit with the internal sliding block, the left piston cavity and the right piston cavity are connected with an oil injection mechanism through electromagnetic valves respectively, and the electromagnetic valves are used for controlling oil pressure inside the left piston cavity or the right piston cavity. The interior volume ratio regulating mechanism has the beneficial effect that the position of the left sliding block and the position of the right sliding block can be regulated more flexibly and conveniently.
Description
technical field [0001] The invention relates to the technical field of single-screw compressors, in particular to an internal volume ratio adjustment mechanism for single-screw compressors. Background technique [0002] A general single-screw compressor includes a main screw rotor and a symmetrically arranged star wheel assembly meshed with it. The compressed gas is sucked into the slot of the screw rotor and sealed by the star wheel. With the rotation of the rotor, the compressed space gradually Reduced and discharged from the exhaust port when a suitable volume is reached. [0003] Volume compression ratio, in the field of general compressors, refers to the degree to which the fluid is compressed, that is, the volume of the fluid when it flows out of the outlet, divided by the maximum enclosed volume, which is determined by the working conditions of the compressor Under normal circumstances, when the compressor produces over-compression or under-compression, it will lead ...
