Abstract
The invention provides a special engagement pair single-screw compressor, which comprises an engagement pair consisting of a cylindrical screw and two plane star wheels in symmetrical arrangement, wherein in the engagement pair, a thread crest width value range of the cylindrical screw is 1.8mm to 3.1mm; the diameter d1 of the cylindrical screw is 120mm to 410mm; a value range of the diameter d2 of the plane star wheels is 1.06d1 to 1.2d1; and a value range of the big tooth depth h is 0.23d1 to 0.3d1. The special engagement pair single-screw compressor has the advantages that more than one percent of displacement of the single-screw compressor displacement can be increased; the volumetric efficiency is improved; and the design belongs to the effective design for energy saving and emission reduction.
Description
Technical field
The present invention relates to single screw compressor field, the engagement pair that the screw rod-star-wheel referring more particularly to single screw compressor is formed.
Background technique
The major part of single screw compressor has screw rod, star-wheel and casing.CP type single screw compressor forms engagement pair by the planar gaterotors of a cylindrical screw and two Central Symmetry layouts, and is arranged on formation compressor main body in casing.Screw spiral trough, casing inner wall and spider piece Topland form the element volume closed.The spiral chute that power during High Rotation Speed passes to screw rod drive star-wheel tooth to rotate, along with star-wheel tooth rotates, make air enter air aspiration cavity by screw rod chamfering end face, then closed by star-wheel gear piece, when being compressed to design pressure, by the exhaust estuary opened at casing inner wall by exhaust passage after discharge.
The casing of single screw compressor has spray hole, oil, water or coolant is sprayed into compression chamber after spray nozzle atomization, plays cooling, sealing, absorbing, noise elimination and lubrication.Single-screw compressor screw head number Z1=6, spider piece tooth number Z 2=11, screw rod turns 180 °.Current single-screw compressor screw-star-wheel engagement pair design parameter is: as Fig. 1, after screw diameter d1 determines, star-wheel diameter d 2=1 ~ 1.05d1, centre distance A=0.8d1, distance a=0.3d1, large tooth depth h=0.2 ~ 0.225d1, distance b=0.1438 ~ 0.1615d1.According to situation and the laboratory data of products application, also has room for promotion according to the compressor displacement of above-mentioned parameter design.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of special engagement pair single screw compressor, and its screw rod-star-wheel engagement pair is compared existing engagement pair on compressor displacement, obtained objectively raising.
Technological scheme of the present invention is: a kind of special engagement pair single screw compressor, comprise the engagement pair be made up of a cylindrical screw and two planar gaterotors be arranged symmetrically with, in described engagement pair, cylindrical screw addendum width span is 1.8mm ~ 3.1mm, cylindrical screw diameter d 1=120mm ~ 410mm, the span of planar gaterotors diameter d 2 is 1.06d1 ~ 1.2d1, and the span of large tooth depth h is 0.23d1 ~ 0.3d1.
The present invention can increase more than single screw compressor discharge capacity one percentage point, improves volumetric efficiency.
Accompanying drawing explanation
Fig. 1 is screw rod of the present invention-star-wheel engagement pair structural representation.
