Abstract
The utility model discloses a single-screw air compressor. The compressor comprises a shell, a screw and star wheels, wherein the screw comprises a screw I, a screw II, a screw III, a screw IV and a screw V; an air inlet and an air outlet are formed in the shell; an electromotor is arranged at the inner side of the shell and is connected with the screw I; the tail end of the screw I is connected with an oil-gas separator; a synchronous gear and a rotor are arranged on the screw I; the screw II and the screw III are arranged at the upper end of the rotor; the screw IV and the screw V are arranged at the lower end of the rotor; the star wheels can be arranged on the screw IV and the screw V; the rotor is movably connected with the star wheels. Wheel grooves and spiral grooves in the rotor are consistent in size and are meshed mutually, so that no clearance is formed between the star wheels and the rotor, and the sealing effect is good.
Description
Technical field
The utility model relates to air compressor field, relates in particular to a kind of single-screw air compressor.
Background technique
The major part of single-screw air compressor has screw rod and star-wheel, and single-screw air compressor is a kind of novel rotary compressor tool, and its structure is very simple.The efficiency of single-screw air compressor is controlled by a great extent the back lash of screw channel and star-wheel side.Owing to there is gap between screw channel and the gear teeth of star-wheel, the high pressure air cognition being compressed is leaked to the low-pressure gas for being compressed by this gap, thus loss compression work, the efficiency of reduction compressor.And the number of star-wheel is single and cannot change on current single-screw air compressor, the situation that not only can not occur for multiple volume flow, once and star-wheel damage with regard to whole compressor, all can scrap, wasting manpower and material resources.Therefore, need a kind of new technological method to address the above problem.
Model utility content
The utility model provides a kind of single-screw air compressor of simple in structure, diverse in function.
The technical solution adopted in the utility model: a kind of single-screw air compressor comprises housing, screw rod and star-wheel, screw rod comprises screw rod I, screw rod II, screw rod III, screw rod IV and screw rod V, housing is provided with suction port and relief opening, housing inner side is provided with motor, motor is connected with screw rod I, the tail end of screw rod I is connected with deaerator, screw rod I is provided with synchromesh gear and rotor, the upper end of rotor is provided with screw rod II and screw rod III, the lower end of rotor is provided with screw rod IV and screw rod V, screw rod II, screw rod III, in screw rod IV and screw rod V, star-wheel can be installed, rotor is flexibly connected with star-wheel.
Above-mentioned rotor is provided with 6-8 bar helical groove, and star-wheel is provided with race, race and epitrochanterian helical groove consistent size and intermesh.
Above-mentioned star-wheel is 2-4 and the both sides up and down that are symmetrically distributed in rotor, and the quantity of the gear teeth of star-wheel is 10-12.
The beneficial effects of the utility model: race and epitrochanterian helical groove consistent size and intermesh, make between star-wheel and rotor very close to each other, good sealing effect; Dismountable 4 star-wheels are installed, and when the volume flow of compressor inside changes, the quantity of the star-wheel of replaceable compressor inside is to adapt to the situation of various volume flows; Star-wheel is demountable, can change it, easily and effectively when star-wheel is damaged.
