Embodiment
First object of the present invention is to provide a kind of centrifugal compressor, and the structural design of this centrifugal compressor can simplify the oil circuit outside gear-box effectively, and second object of the present invention is to provide a kind of air conditioner comprising above-mentioned centrifugal compressor.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 2, the centrifugal compressor that the embodiment of the present invention provides comprises gear-box, main fuel tank 6, top petrol tank 2 and bearing 5, and main fuel tank 6, top petrol tank 2 and bearing 5 are all arranged on gear-box inside, the position of top petrol tank 2 should higher than the position of bearing 5, lubricant oil during centrifugal compressor unexpected power-off in top petrol tank 2 due to Action of Gravity Field to bearing 5 for lubricant oil.Focus on, the oil outlet of main fuel tank 6 is communicated with the filler opening of top petrol tank 2 by the first oil feed line 9, the first oil feed line 9 is serially connected with oil pump 7, oil cooler 8 and filter 1, and in oil cooler 8 and filter 1 one is arranged on gear-box inside.Namely the lubricant oil in top petrol tank 2 is supplied by main fuel tank 6, and lubricant oil enters in top petrol tank 2 through oil pump 7, oil cooler 8 and filter 1.Oil cooler 8 or filter 1 are arranged on gear-box inside, and then the pipeline of oil cooler 8 or filter 1 is arranged on the inside of gear-box, enormously simplify the pipeline of gear-box outside, simplify the oil circuit of gear-box outside, make whole unit outward appearance more succinct.
In order to optimize technique scheme further, wherein only can be arranged on gear-box inside by filter 1, oil cooler 8 is arranged on the outside of gear-box.In order to farthest simplify exterior line, it is inner that filter 1 can be arranged on top petrol tank 2, and the filler opening of top petrol tank 2 and oil outlet are separated by filter 1, namely top petrol tank 2 inside is divided into two spaces by filter 1, one of them space is communicated with filler opening, another space is communicated with oil outlet, and the lubricant oil in the space be communicated with filler opening need enter another space through filter 1, and then discharges from oil outlet.During replacing filter 1 like this, the cover plate only need opening top petrol tank 2 is changed, more fast convenient.
Certainly, it is outside that filter 1 also can be positioned at top petrol tank 2, or only oil cooler 8 is arranged on gear-box inside, in this no limit.
Flowed to by main fuel tank 6 to top petrol tank 2, the first oil feed line 9 is connected in series successively oil pump 7, oil cooler 8 and filter 1, and is provided with valve 3 between oil pump 7 and oil cooler 8.So can be controlled the lubricant oil volume entered in top petrol tank 2 by the valve 3 between oil pump 7 and oil cooler 8, and lubricant oil on the first oil feed line 9 can be controlled whether circulate.Further, the oil outlet of top petrol tank 2 by the oily channel connection of the second oil feed line 4 with bearing 5, and the second oil feed line 4 is provided with valve 3.After valve 3 on closedown second oil feed line 4 like this and the valve 3 between oil pump 7 and oil cooler 8, just no longer circulate in oil cooler 8 and filter 1 lubricant oil, can change oil cooler 8 and filter 1 easily.
In order to make the lubricant oil in top petrol tank 2 be supplied to bearing 5 smoothly, top petrol tank 2 can be arranged on the top in gear-box, 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 also can be arranged on its sidewall, in this no limit.
Simplify the pipeline outside gear-box and support to try one's best, wherein oil cooler 8 can be plate type heat exchanger, and oil cooler 8 is fixed on the outer wall of gear-box.Certainly, oil cooler 8 can also be other structure, in this no limit.
Based on the centrifugal compressor provided in above-described embodiment, present invention also offers a kind of air conditioner, this air conditioner comprises any one centrifugal compressor in above-described embodiment.The centrifugal compressor in above-described embodiment is have employed, so the beneficial effect of this air conditioner please refer to above-described embodiment due to this air conditioner.
