The utility model discloses be provided with on the casing and open the cooling fluid passage that has jet lubrication cistern seam, this line of rabbet joint width size slightly is greater than the thermodynamics calculation, guarantee that the compressed gas temperature all can not surpass permission operating temperature under any operating mode, the cooling fluid passage installs inside has branch liquid pipe, it is equipped with aperture or narrow slit to divide liquid to manage, the distributive value of compressor is controlled to the branch liquid pipe that contains different area apertures or narrow slit through the change, ensure the compressor reliability service, it repeats the dismouting to have the casing of avoiding, wearing and tearing are minimum, the resistance is minimum, reduce the specific power, energy saving and emission reduction, when the advantage.
Description
Technical field
The utility model belongs to compressor apparatus field, relates to a kind of liquid-jet device of single screw compressor.
Background technique
In gas compression processes, heat can be produced.Superpose to not make heat and equipment is caused damage.Cause equipment cisco unity malfunction, need to cool by pressurized gas in compression process, allow cooling liquid take away the heat of compression.Equipment is made to carry out work in the operating temperature range allowed.The existing type of cooling to the flow of cooling liquid and the uniform state of flowing uncontrollable.The size of cooling hole slot changes along with the rising of temperature, and theoretical result of calculation inevitably occurs error in the using process of reality.Determine that the process of Gap size is too loaded down with trivial details, operation link is many, easily produces error, often can not produce a desired effect, and careless slightly whole casing all can be scrapped.Therefore, for the above-mentioned defect existed in currently available technology, be necessary to study in fact, to provide a kind of scheme, solve the defect existed in prior art.
Model utility content
The utility model is for determining in prior art that the process of Gap size is too loaded down with trivial details, operation link is many, the shortcomings such as easy generation error, provide a kind of setting by arranging cooling fluid passage, avoid casing to repeat the liquid-jet device of a kind of single screw compressor of dismounting.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A liquid-jet device for single screw compressor, comprises casing, is provided with screw rod and star-wheel in casing, and described screw rod and star-wheel engage each other, and star-wheel is fixed by upper bearing (metal), lower bearing, and casing is also provided with cooling fluid passage.Casing is provided with the cooling fluid passage having jet lubrication liquid bath seam, this slot width size, slightly larger than the result of calculation of thermodynamics, guarantees that pressurized gas temperature all can not exceed permission operating temperature under any operating mode.
As preferably, in cooling fluid passage, be provided with the line of rabbet joint.
As preferably, in cooling fluid passage, ram's horns is set.Cooling fluid passage inner sleeve, in ram's horns, can make the flow velocity of cooling liquid and flow more even, and can control compressor operating temperature and be in zone of reasonableness.
As preferably, ram's horns is identical with cooling fluid passage length.
As preferably, ram's horns is provided with aperture.
As preferably, aperture is circular.Adopt circular aperture tool, when girth is identical, there is maximum area, the advantage such as have that wearing and tearing are minimum, resistance is minimum and attractive in appearance.
As preferably, ram's horns is provided with narrow slit.Ram's horns is evenly provided with some circular apertures or narrow slit, throttling and shunting are carried out to cooling liquid, make the more uniform cooling compressor of cooling liquid, guarantee the delivery temperature effectively controlling compressor, reduce specific power, reach the object of energy-saving and emission-reduction.
As preferably, screw rod is cylindrical.
As preferably, star-wheel is the planar gaterotors that two Central Symmetries are arranged.
Compared with prior art, the beneficial effects of the utility model are as follows: the utility model is by arranging the liquide separating tube in cooling fluid passage, the fuel injection quantity of compressor is controlled by changing the liquide separating tube containing different area aperture or narrow slit, guarantee compressor reliable operation, there is minimum, the minimum specific power reduction of resistance of wearing and tearing, energy-saving and emission-reduction, avoid casing to repeat the advantages such as dismounting.
