Embodiment
First object of the present utility model is to provide a kind of radial compressor, the structure design of this radial compressor can simplify the oil circuit outside wheel casing effectively, and the 2nd object of the present utility model is to provide a kind of conditioner comprising above-mentioned radial compressor.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 2, the radial compressor that the utility model embodiment provides comprises wheel casing, main tank 6, top petrol tank 2 and bearing 5, and main tank 6, top petrol tank 2 and bearing 5 are all arranged on wheel casing inside, the position of top petrol tank 2 should higher than the position of bearing 5, during radial compressor unexpected power-off the lubricating oil in top petrol tank 2 due to action of gravity to bearing 5 for lubricating oil. Focusing on, the oil outlet of main tank 6 is connected with the oil-in of top petrol tank 2 by the first oil supply line 9, and the first oil supply line 9 is serially connected with oil pump 7, oil cooler 8 and strainer 1, and in oil cooler 8 and strainer 1 one is arranged on wheel casing inside. Namely the lubricating oil in top petrol tank 2 is supplied by main tank 6, and lubricating oil enters in top petrol tank 2 through oil pump 7, oil cooler 8 and strainer 1. Oil cooler 8 or strainer 1 are arranged on wheel casing inside, and then the pipeline of oil cooler 8 or strainer 1 is arranged on the inside of wheel casing, enormously simplify the pipeline of wheel casing outside, simplifies the oil circuit of wheel casing outside so that whole unit outward appearance is more succinct.
In order to optimize technique scheme further, wherein only can being arranged on wheel casing inside by strainer 1, oil cooler 8 is arranged on the outside of wheel casing. In order to farthest simplify exterior line, it is inner that strainer 1 can be arranged on top petrol tank 2, and the oil-in of top petrol tank 2 and oil outlet are separated by strainer 1, namely top petrol tank 2 inside is divided into two spaces by strainer 1, one of them space is connected with oil-in, another space is connected with oil outlet, and the lubricating oil in the space being connected with oil-in need to enter another space through filter 1, and then discharges from oil outlet. When so changing strainer 1, the cover plate that only need to open top petrol tank 2 is changed, more fast convenient.
Certainly, it is outside that strainer 1 can also be positioned at top petrol tank 2, or only oil cooler 8 is arranged on wheel casing inside, in this no limit.
Flow to by main tank 6 to top petrol tank 2, the first oil supply line 9 is connected in series oil pump 7, oil cooler 8 and strainer 1 successively, and between oil pump 7 and oil cooler 8, be provided with valve 3. So can be controlled the lubricating oil volume entered in top petrol tank 2 by the valve 3 between oil pump 7 and oil cooler 8, and can control whether lubricating oil on the first oil supply line 9 circulates. Further, the oil outlet of top petrol tank 2 is by the oily channel connection of the 2nd oil supply line 4 with bearing 5, and is provided with valve 3 on the 2nd oil supply line 4. So closing the valve 3 on the 2nd oil supply line 4 and after the valve 3 between oil pump 7 and oil cooler 8, just no longer circulate in oil cooler 8 and strainer 1 lubricating oil, it is possible to changes oil cooler 8 and strainer 1 easily.
In order to make the lubricating oil in top petrol tank 2 be supplied to bearing 5 smoothly, it is possible to the top being arranged on by top petrol tank 2 in wheel casing, so farthest ensure that the height of top petrol tank 2. And the oil outlet of top petrol tank 2 is arranged on bottom it, namely the oil outlet of top petrol tank 2 is positioned at the bottom of top petrol tank 2, and the oil outlet of certain top petrol tank 2 can also be arranged on its sidewall, in this no limit.
In order to simplify the pipeline outside wheel casing and support as far as possible, wherein oil cooler 8 can be plate-type heat exchanger, and oil cooler 8 is fixed on the outer wall of wheel casing. Certainly, oil cooler 8 can also be other structure, in this no limit.
Based on the radial compressor provided in above-described embodiment, the utility model additionally provides a kind of conditioner, and this conditioner comprises any one radial compressor in above-described embodiment. The radial compressor in above-described embodiment is have employed, so the useful effect of this conditioner please refer to above-described embodiment due to this conditioner.
In this specification sheets, each embodiment adopts the mode gone forward one by one to describe, and what each embodiment emphasis illustrated is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are enable to realize or use the utility model. To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments. Therefore, the utility model can not be limited in these embodiments shown in this article, but be met the widest scope consistent with principle disclosed herein and features of novelty.
