Abstract
The utility model provides a helical -lobe compressor's oil spout structure, it can solve the unable problem of adjusting the distributive value of traditional helical -lobe compressor oil spout structure. Its open in compressor host shell lower part have link up each other send oily passageway and nozzle opening, send oily passageway still to be linked together with the bearing oil passageway, send and be equipped with the step junction surface between oily passageway and the nozzle opening, its characterized in that: install the fuel sprayer that can dismantle the change in sending oily passageway and nozzle opening, the fuel sprayer includes head and afterbody, and the afterbody cooperation of fuel sprayer is installed in sending oily passageway and during the head of fuel sprayer stretches into the nozzle opening, still offered the branch oilhole on the afterbody of fuel sprayer, divides oilhole and bearing oil passageway to be linked together.
Description
Technical field
The utility model relates to helical-lobe compressor field, is specially a kind of oil injection structure of helical-lobe compressor.
Background technique
In fuel injection helical lobe compressor, in active chamber, often spray into the lubricant oil with certain pressure, the oil sprayed in compressor mainly contains cooling, sealing, lubrication and noise reduction four functions.Such as, but according to the difference of operating conditions and compressed medium in helical-lobe compressor actual motion working procedure, fuel injection quantity has very large difference, when exhaust pressure is higher, Leakage Gas is comparatively large, and volumetric efficiency is lower, and required heat exchange amount increases, and now suitably should improve fuel injection quantity; In addition, during rotating speed height, relatively reveal loss little, but the wasted work of disturbance oil is comparatively large, so also just require the circulating load suitably reducing oil; If the density of compressed medium is less, Leakage Gas is serious, also should increase the circulating load of oil.And the oil injection structure of traditional helical-lobe compressor is shown in Fig. 1, its lubricant oil is directly from sending the nozzle opening 2 of oily passage 1 front end to spray into main frame, and it cannot meet the adjustment requirement of fuel injection quantity.
Summary of the invention
For the problems referred to above, the utility model provides a kind of oil injection structure of helical-lobe compressor, and it can solve the problem that classic screw compressor oil injection structure cannot regulate fuel injection quantity.
A kind of oil injection structure of helical-lobe compressor, it has in compressor host lower housing portion and mutually throughly send oily passage and nozzle opening, describedly oily passage is sent also to be connected with bearing oil passage, described sending between oily passage and nozzle opening is provided with step type joining portion, it is characterized in that: send in oily passage and nozzle opening described the oil nozzle being provided with and detachably changing, described oil nozzle comprises head and afterbody, the afterbody of described oil nozzle coordinate be installed on described in send in oily passage and the head of described oil nozzle stretches in described nozzle opening, the afterbody of described oil nozzle also offers a point oilhole, described point of oilhole is connected with described bearing oil passage.
It is further characterized in that:
Spielpassung between the head of described oil nozzle and described nozzle opening;
The step type auxiliary section matched with described step type joining portion is provided with between described oil nozzle head and afterbody;
The afterbody periphery of described oil nozzle is provided with outside thread, described in send the inner circumferential of oily passage to be provided with the internal thread matched with the outside thread of the afterbody periphery of described oil nozzle, the afterbody of described oil nozzle is threaded with described sending between oily passage;
The afterbody inner circumferential of described oil nozzle is provided with interior hexagonal structure.
The beneficial effects of the utility model are: its send oil by with spray orifice hole in the oil nozzle detachably changed is installed, can the oil nozzle of assembling suitable header internal diameter be selected according to actual conditions thus make unit performance reach the best in actual use.

Fig. 2 is helical-lobe compressor oil injection structure schematic diagram of the present utility model;
Fig. 3 is the structure for amplifying schematic diagram of the oil nozzle in helical-lobe compressor oil injection structure of the present utility model;
Fig. 4 is that schematic diagram is looked on the right side of Fig. 3.
Embodiment
See Fig. 2, helical-lobe compressor oil injection structure of the present utility model, its host shell bottom has mutually throughly send oily passage 1 and nozzle opening 2, oily passage 1 is sent also to be connected with bearing oil passage 3, send between oily passage 1 and nozzle opening 2 and be provided with step type joining portion 4, the oil nozzle 5 detachably changed is installed sending in oily passage 1 and nozzle opening 2, oil nozzle 5 comprises head 5-1 and afterbody 5-2, see Fig. 3, the afterbody 5-2 of oil nozzle 5 coordinates to be installed on and to send in oily passage 1 and the head 5-1 of oil nozzle 5 stretches in nozzle opening 2, the afterbody 5-2 of oil nozzle 5 also offers a point oilhole 5-3, oilhole 5-3 is divided to be connected with bearing oil passage 3.
Spielpassung between the head 5-1 external diameter φ d of the oil nozzle 5 and internal diameter φ D of nozzle opening 1;
The step type auxiliary section 5-4 matched with step type joining portion 4 is provided with between the head 5-1 of oil nozzle 5 and afterbody 5-2;
The afterbody 5-2 periphery of oil nozzle 5 is provided with outside thread, send the inner circumferential of oily passage 1 to be provided with the internal thread matched with the outside thread of the afterbody periphery of oil nozzle, and the afterbody 5-2 of oil nozzle is threaded with sending between oily passage 1;
The afterbody 5-2 inner circumferential of oil nozzle 5 is provided with interior hexagonal structure 5-5, sees Fig. 4, only needs to be stretched in interior hexagonal structure 5-5 oil nozzle 5 to be screwed into by inner hexagon spanner to send in oily passage 1 when oil nozzle 5 assembles.
Time oily to jet lubrication in compressor host by helical-lobe compressor oil injection structure of the present utility model, lubricant oil is divided into two-way, wherein a road lubricant oil is spurted in main frame through the head 5-1 of oil nozzle 5, and another road lubricant oil is entered in the bearing oil passage 3 of main frame by point oilhole 5-3 on the afterbody of oil nozzle 5 and carries out fuel feeding to bearing.
In actual use, for same compressor host, it can select the oil nozzle 5 of assembling different head diameter phi A to carry out the requirement of satisfied different fuel injection quantity according to the requirement of actual conditions.
