Abstract
The utility model discloses an energy-saving single-screw compressor which comprises an engagement pair, wherein the engagement pair consists of a cylindrical screw and two symmetrically-distributed plane star wheels, the engagement pair is installed in a shell, and the center distance A between the engagement pair consisting of the cylindrical screw and the two plane star wheels and the shell is less than 0.8 time of the diameter d1 of the cylindrical screw. The energy-saving single-screw compressor further reduces the specific power and saves more energy than an existing product.
Description
Technical field
The utility model relates to the single screw compressor field, refers more particularly to the centre distance of the engagement pair of single screw compressor cylindrical screw and plane star-wheel composition to housing.
Background technique
Single screw compressor can be widely used in the fields such as nuclear power station, submarine, air-conditioning, refrigeration, heat pump, cement, iron and steel, mine, weaving, machinery, and its core technology is processing, measurement and the assembling that screw rod, star-wheel and housing form engagement pair.But state's inner screw, star-wheel Special Purpose Machine for Processing and processing technology precision have restricted the development of single screw compressor, single stage compression universal machine efficiency level is mostly in three grades and secondary level, and based on above-mentioned present situation, the single screw compressor technology is the space that has development.
The major part of single screw compressor has screw rod, star-wheel and casing, and CP type single screw compressor forms engagement pair by the plane star-wheel of a cylindrical screw and two Central Symmetry layouts, is contained in casing and forms.Screw spiral trough, casing inner wall and spider piece Topland form the element volume of sealing.Power during High Rotation Speed passes on the spiral chute of screw rod and drives the star-wheel tooth and rotate, along with the star-wheel tooth rotates, make air enter air aspiration cavity by screw rod chamfering end face, then sealed by the star-wheel gear piece, while being compressed to design pressure, by opening exhaust estuary at casing inner wall, discharge after by exhaust passage.Wherein, the engagement pair that cylindrical screw and plane star-wheel form is designated as A to the centre distance of housing, the centre distance A generally adopted in industry at present >=0.8 d1, and the d1 here refers to the cylindrical screw diameter.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of energy-saving single-bolt compressor is provided, and the single screw compressor product specific power of producing in more current industry is less, more energy-conservation.
The technical solution of the utility model is: a kind of energy-saving single-bolt compressor, form engagement pair by a cylindrical screw and two plane star-wheels that are arranged symmetrically with, this engagement pair is arranged in housing, and the engagement pair that cylindrical screw and plane star-wheel form and the centre distance A of housing are less than 0.8 times of cylindrical screw diameter d 1.
As centre distance A<0.8d1, at capacity rating q
vNdetermine in situation cylindrical screw diameter d 1, screw axial minimum tooth top width, meshingangleα with rated pressure
tidentical, its centre distance A reduces because of than centre distance A>=0.8 d1 the time, star-wheel facewidth b narrows down, whole depth h is elongated, star-wheel flank of tooth area and center of gravity G are slightly same, area center of gravity G diminishes apart from the screw axis distance R, and on screw spiral trough, gas load is slightly same, and namely rotary inertia J=GR diminishes, wasted work is little, so specific power P=W/q
vNkW/m
3/ min little (W is air horsepower), so single screw compressor energy-saving low-carbon, tranquility environmental protection, long-lived reliable more.
The utility model has further reduced specific power, makes single screw compressor more energy-conservation than existing product.
The accompanying drawing explanation
Fig. 1 is depicted as screw diameter d1, engagement pair total displacement q
vNunder the condition identical with pressure, star-wheel facewidth b and the asynchronous schematic diagram of whole depth h; Corresponding parameter when wherein the mark in the alphabetical lower right corner " greatly " represents A>=0.8 d1, corresponding parameter when " little " represents A<0.8d1.
Embodiment
A kind of energy-saving single-bolt compressor, form engagement pair by a cylindrical screw and two plane star-wheels that are arranged symmetrically with, this engagement pair is contained in casing, screw channel, casing inner wall and the star-wheel flank of tooth form the element volume of sealing, along with the movement of star-wheel tooth, the element volume of sealing changes, and corresponding gas enters the screw rod tooth socket space by air aspiration cavity, reach after compression the design pressure value, drained in separator by the exhaust estuary of opening on housing.
In Fig. 1, the cylindrical screw diameter is d1, the engagement pair that cylindrical screw and plane star-wheel form and the centre distance A=0.6d1 of housing.At capacity rating q
vNdetermine in situation screw diameter d1, screw axial minimum tooth top width, meshingangleα with rated pressure
tidentical, its centre distance A reduces because of than centre distance A>=0.8 d1 the time, star-wheel facewidth b narrows down, whole depth h is elongated, star-wheel flank of tooth area and center of gravity G are slightly same, area center of gravity G diminishes apart from the screw axis distance R, and on screw spiral trough, gas load is slightly same, and namely rotary inertia J=GR diminishes, wasted work is little, specific power P=W/q
vNkW/m
3/ min little (W is air horsepower), single screw compressor is further energy-conservation.
The above, it is only preferred embodiments of the present utility model, not technical scope of the present utility model is imposed any restrictions, any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of the technical program.
Claims (1)
