Description
Technical field
The utility model relates to the compressor of the screw shaft that a kind of interior single groove metal-to-metal adhesive adhesion coating fills, relate in particular to a kind of by the toothed sheet parts of multi-disc be inserted in after stack, step up to form after axle and quench after the compressor of screw shaft of impregnation.
Background technology
Helical-lobe compressor, also claim screw compressor, comprise screw air compressor and screw rod technique compressor (vinyl chloride compressor etc.), helical-lobe compressor is divided into single screw compressor and double-screw compressor, and helical-lobe compressor is to utilize screw shaft shape rotor to compress and pumped (conveying) medium do gyration in cylinder body.
It is high that helical-lobe compressor has reliability, and parts are few, there is no consumable accessory, thereby its running is reliable, and the life-span is long, and general screw machine host header reaches 30 years projected life; Convenient operating maintenance, automaticity is high, and operating personnel, without through long-time professional training, realize unmanned running; Dynamic equilibrium is good, there is no unbalance inertia force, and machine is high speed operation reposefully, realizes foundation-free running; Strong adaptability, has the advantages that to force gas transmission, and volume flow is subject to the impact of pressure at expulsion hardly, in broad condition range, can keep higher efficiency, without any changes in the situation that, be applicable to various working at compressor arrangement, so be easy to sizing batch production; Multi-phase mixed delivering, in fact leaves gap between the rotor flank of tooth, thereby ability hydraulic shock, can force feed containing the gas of liquid, containing dusty gas, easily polymerizable gas etc.; Guiding valve Flow-rate adjustment, does not need to return stream, can effectively reduce the advantages such as energy consumption, and therefore, helical-lobe compressor is widely used.
