Abstract
The invention relates to a single screw compressor with small specific power, in particular to a mute and reliable single screw compressor with energy saving, low carbon, environment protection and long service life. The single screw compressor with small specific power is characterized in that a cylindrical screw and two symmetrically arranged planer star wheels form a meshed pair which is arranged in an enclosure; a screw spiral groove, the inner wall of the enclosure and the star wheel tooth surface form a sealed element volume; along with the movement of the teeth of the star wheels, the volume of a sealed element changes, corresponding gas enters the space of the screw toothspace from a suction cavity, reaches a design pressure value after being compressed and is discharged into a gas-oil separator through a venting triangular mouth on the enclosure, the diameter of the screw is d1, and the center distance A of the screw, the star wheel meshing pair and the enclosure is less than 0.8d1. The invention has the beneficial effects of further reducing specific power and causing the single screw compressor to save energy to become an environmentally-friendly product.
Description
Technical field
The present invention relates to a kind of single screw compressor field, refer more particularly to a kind of " energy-saving low-carbon, tranquility environmental protection, long-lived reliable single screw compressor ".
Background technique
The straight line planar envelope CP of world today type single screw compressor comprises single-screw air compressor (the oil spout single-screw air compressor has NBS), single Spiral Lobe Refrigeration Compressor and single-screw expander.Its product successfully is used for numerous industries such as nuclear power station, submarine, air-conditioning, refrigeration, heat pump, cement, iron and steel, mine, weaving, machinery, environmental protection except that single-screw expander, is a significant innovation in 21st century Compressor Technology field.Its core technology is processing, measurement and the assembling that screw rod, star-wheel and housing constitute engagement pair, especially engagement pair flank molded lines is centered apart from A by 1 long straight edge line l blade, process the flank molded lines technology (having obtained patent) of gear shaper without theoretical errors by velocity ratio i generate, the single screw compressor technology attains a new height.Based on above-mentioned present situation, the single screw compressor technology is the space that has development, and the inventor has invented single screw compressor with small specific power makes its product rise to efficiency type green product.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art technical problem to be solved is: a kind of single screw compressor screw rod, star-wheel and housing engagement pair centre distance A＜0.8d are provided
1Product, at present generally adopt A 〉=0.8d in the industry
1Compressor product specific power is little.
The technical solution adopted for the present invention to solve the technical problems is:
Single screw compressor with small specific power engagement pair centre distance A＜0.8d
1At capacity rating q
VNDetermine under the situation screw diameter d with rated pressure Mpa
1, screw axial minimum tooth top width b
1, meshingangle
tIdentical, because of than centre distance A 〉=0.8d
1The time its centre distance A reduce, star-wheel facewidth b narrows down, whole depth h is elongated, star-wheel flank of tooth area and center of gravity G slightly with, area center of gravity G diminishes apart from the screw axis distance R, and gas load omits together on the screw spiral trough, and just rotary inertia J=GR diminishes, wasted work is little, specific power P=W
Sh/ q
VNLittle (the W of KW/m3/min
ShAir horsepower), energy-saving low-carbon, tranquility environmental protection, the further energy-conservation green single screw compressor that becomes of long-lived reliable single screw compressor.
The beneficial effect of single screw compressor of the present invention is:
Further reduce specific power, make the more energy-conservation green product that becomes of single screw compressor product.
Description of drawings:
Figure 1 shows that screw diameter d
1, screw rod minimum tooth top width b
1, engagement pair total displacement q
VNWith the schematic representation when centre distance A, star-wheel facewidth b, star-wheel whole depth h different value under the pressure MPa same case.
Figure 2 shows that screw diameter d
1, engagement pair total displacement q
VNUnder the condition identical with pressure Mpa, star-wheel facewidth b is different with whole depth h, and its area center of gravity G omits together, but area center of gravity G
Little AFrom screw axis R
Little AClosely, promptly rotary inertia J=GR is little, and wasted work is few.
Embodiment
During the single screw compressor design, determine screw diameter d
1After, engagement pair centre distance is necessarily got A＜0.8d
1
In Fig. 1 and Fig. 2, a kind of single screw compressor with small specific power, plane star-wheel by a cylindrical screw and two symmetric arrangement is formed engagement pair, this engagement pair is contained in the casing, screw channel, casing inner wall and the star-wheel flank of tooth constitute the element volume of sealing, along with moving of star-wheel tooth, the element volume of sealing changes, corresponding gas enters the screw rod tooth socket space by air aspiration cavity, reach the design pressure value after compression, drained in the deaerator by the exhaust estuary of opening on housing, screw diameter is d
1, the centre distance A＜0.8d of screw rod, star-wheel engagement pair and housing
1At capacity rating q
VNDetermine under the situation screw diameter d with rated pressure Mpa
1, screw axial minimum tooth top width b
1, meshingangle
tIdentical, because of than centre distance A 〉=0.8d
1The time its centre distance A reduce, star-wheel facewidth b narrows down, whole depth h is elongated, star-wheel flank of tooth area and center of gravity G slightly with, area center of gravity G diminishes apart from the screw axis distance R, and gas load omits together on the screw spiral trough, and just rotary inertia J=GR diminishes, wasted work is little, specific power P=W
Sh/ q
VNLittle (the W of KW/m3/min
ShAir horsepower), energy-saving low-carbon, tranquility environmental protection, the further energy-conservation green single screw compressor that becomes of long-lived reliable single screw compressor.The present invention is the first-selection of producing green single screw compressor.
The above, it only is a kind of preferred embodiment of single screw compressor with small specific power of the present invention, be not that technical scope of the present invention is imposed any restrictions, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention above any trickle modification, equivalent variations and modification that embodiment did.
