Abstract
Have an oil-flooded screw air compressor for Novel oil inlet joint, comprise screw host, return tube, screw host offers jet, also comprise a fuel inlet fitting, fuel inlet fitting has axial through hole, and the leading portion of through hole is oil spout throttling pore; The head threads of fuel inlet fitting screws in jet, and the tailing screw flight of this fuel inlet fitting connects return tube; The middle part of fuel inlet fitting is provided with the tap hole with through hole UNICOM, and also comprise ram's horns, ram's horns is threadedly connected in tap hole, and the end of ram's horns aims at the bearing place of screw host.Fuel inlet fitting structure of the present utility model is simple, and low cost of manufacture, not easily produces leakage of oil; Screw host fuel inlet fitting only carries out throttling for screw host filler opening place, can not affect the flow of other oilings place of unit, and can ensure the normal operation of unit, the utilization ratio of withdrawing oil is high; Be provided with ram's horns, specific aim lubrication can be carried out to main frame bearing place.
Description
Technical field
The utility model relates to a kind of oil-flooded screw air compressor.
Background technique
One of fuel injection screw air compressor is in running, and the size of its fuel injection quantity ensures that screw host normally works, and the important indicator of quality of filling gas quality.Lubricant oil is mixed into deaerator by screw host relief opening and pressurized air, and separation is completed in deaerator, then the lubricant oil after being separated flows through the parts such as cooler, oil strainer, entered by screw host jet and circulate, to guarantee cooling, the sealing of screw host and to lubricate; Screw host is when designing, and screw host factory generally can arrange aperture at main frame jet, be directly connected with return tube, easily produce Leakage, and the utilization ratio of withdrawing oil is low.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing oil-flooded screw air compressor, the utility model provides the high oil-flooded screw air compressor with Novel oil inlet joint of utilization ratio of a kind of not easy oil leakage, withdrawing oil.
The technical scheme in the invention for solving the technical problem is: a kind of oil-flooded screw air compressor with Novel oil inlet joint, comprise screw host, return tube, described screw host offers jet, also comprise a fuel inlet fitting, described fuel inlet fitting has axial through hole, and the leading portion of described through hole is oil spout throttling pore;
The front portion of described fuel inlet fitting is provided with front outside thread, the afterbody of described fuel inlet fitting is provided with rear outside thread, the jet described in head threads screw-in of this fuel inlet fitting, the return tube described in tailing screw flight connection of this fuel inlet fitting, the oil in return tube finally sprays in screw host by oil spout throttling pore through through hole;
The middle part of described fuel inlet fitting is provided with the tap hole with described through hole UNICOM, and also comprise ram's horns, described ram's horns is threadedly connected in described tap hole, and the end of described ram's horns aims at the bearing place of screw host.
The beneficial effects of the utility model are: 1. screw host fuel inlet fitting structure described in is simple, are easy to produce install, and low cost of manufacture, not easily produces leakage of oil; 2. screw host fuel inlet fitting described in can meet the oil inlet quantity of different unit with money screw host, thus reduces oil consumption; 3. screw host fuel inlet fitting described in only carries out throttling for screw host filler opening place, can not affect the flow of other oilings place of unit, and can ensure the normal operation of unit, the utilization ratio of withdrawing oil is high.4. be provided with ram's horns, specific aim lubrication can be carried out to main frame bearing place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of fuel inlet fitting.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of oil-flooded screw air compressor with Novel oil inlet joint, comprise screw host 1, return tube 2, described screw host 1 offers jet, also comprise a fuel inlet fitting 3, described fuel inlet fitting 3 has axial through hole 4, and the leading portion of described through hole 4 is oil spout throttling pore 5.
The front portion of described fuel inlet fitting 3 is provided with front outside thread, the afterbody of described fuel inlet fitting 3 is provided with rear outside thread, the jet described in head threads screw-in of this fuel inlet fitting 3, the return tube 2 described in tailing screw flight connection of this fuel inlet fitting 3, the oil in return tube 2 is finally sprayed in screw host 1 by oil spout throttling pore 5 through through hole 4.
The middle part of described fuel inlet fitting 3 is provided with the tap hole 6 with described through hole 4 UNICOM, also comprises ram's horns 7, and described ram's horns 7 is threadedly connected in described tap hole 6, and the end of described ram's horns 7 aims at the bearing place of screw host 1.
Fuel inlet fitting 3 structure of the present utility model is simple, is easy to produce install, and low cost of manufacture, not easily produces leakage of oil; Fuel inlet fitting 3 can meet the oil inlet quantity of different unit with money screw host, thus reduces oil consumption; Fuel inlet fitting 3 only carries out throttling for screw host filler opening place, can not affect the flow of other oilings place of unit, and can ensure the normal operation of unit, the utilization ratio of withdrawing oil is high; The utility model is provided with ram's horns 7, can carry out specific aim lubrication to main frame bearing place.
