Technical field
The invention belongs to machinery, particularly a kind of stepless pressure regulation type air compressor.
Background technique
At present, the kind of the compressor of machinery industry application is more, can be divided into reciprocal compressor, rotary compressor, turbo type, water ring type, turbo-compressor, Axial Flow Compressor, jet-type compressor and screw compressor etc., wherein the most advanced is helical-lobe compressor, and screw compressor is divided into single screw rod and double-screw type, since the advanced configuration of single screw rod compare with other compressor have rational in infrastructure, equilibrant is good, single-machine capacity is big, noise is low, vibrate advantages such as little, therefore single screw compressor is widely used in gas compression, fields such as refrigerant compression and technology compression, but existing single-screw air compressor has only the cubical content regulation structure of utilizing sliding valve structure, the function of still unmatchful exhaust pressure stepless speed regulation, it is that outer control valve and automatical control system are realized that pressure is regulated, do not realize from compressor inner structure, its compression ratio can not change, so there is not energy saving effect after the pressure regulation.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of simple in structure, can be according to regulating the exhaust outlet of compressor position automatically with the size of atmospheric pressure, the adjustment of realization compression ratio reaches energy-conservation stepless pressure regulation type air compressor.
The technological scheme that technical solution problem of the present invention adopts is: stepless pressure regulation type air compressor comprises lower body, front cover, screw axis, screw rod, spider gear shaft, star-wheel, before, rear bearing, before, the rear bearing upper shield, before, the rear bearing end cap, be characterized in fixing a sender box in the lower right, the outside of front cover, establish a connecting rod in the sender box, the connecting rod substantially horizontal connects signal transmitter, Vertical direction connects a connecting plate that turns shape, the inboard fixedly connected connecting rod of connecting plate, fix an oil cylinder on fore bearing end cap right side, piston in the oil cylinder connects a guide rod, the below of the fixedly connected connecting plate of guide rod right-hand member, in front cover, rear bearing upper shield upper fixed is established a upper machine body, upper machine body is provided with intakeport and relief opening, flexibly connect the slide block on a left end band inclined-plane on the screw rod in upper machine body, the fixedly connected pull bar of slide block right flank, the pull bar right-hand member connects the top of connecting rod, in the connecting rod outside, fixedly establish a protective housing on the sender box.
The invention has the beneficial effects as follows: stepless pressure regulation type air compressor is the slide-valve gear that is provided with pressure stepless speed regulation in inside, move left and right by slide block, change the position of exhaust sealing helix, realization pressure is regulated, when making air compressor work, can be according to the position of regulating the air compressor relief opening with the atmospheric pressure size automatically.Because ambient pressure changes the change be accompanied by compressor pressure ratios, the air horsepower of compressor is also reduced along with pressure and reduce, realize the purpose of energy-saving run, this function is suitable for the operating conditions of different refrigerants, realizes a tractor serves several purposes.
