Abstract
The utility model relates to a rotary-vane vacuum pump, concretely relates to circulative cooling rotary-vane vacuum pump. The existing cooling device has the defects of complex structure, high manufacturing cost, unsatisfactory cooling effect and the like. The utility model provides a circulating cooling rotary vane vacuum pump, which comprises a pump shell and an end cover, wherein the outer side of the pump shell is provided with an outer shell; a gap is formed between the pump shell and the outer shell, and cooling media are filled in the gap. The utility model discloses for prior art's advantage do: simple structure, low cost, easy implementation and good cooling effect.
Description
One, technical field:
The utility model relates to a kind of rotary-vane vaccum pump, is specifically related to a kind of circulation cooling sliding vane rotary vacuum pump.
Two, background technique:
The producer that produces rotary-vane vaccum pump in the market is a lot, but this pump all exists a general problem, temperature height, generally all at 70 ℃～80 ℃, have up to more than 100 ℃, owing to be oil lubrication, oil is burning easily at high temperature, charing, the carbide of generation all has very big wearing and tearing to pump inwall and blade, has destroyed the smooth inwall of pump, produce bigger surface friction drag and heat, thereby formed vicious circle, oil consumption is big, and befouling environment.The producer that has has adopted fan cooled, but utilizes the fan cooled complex structure, the cost height, and also cooling effect is little desirable.
Three, model utility content:
The utility model provides a kind of circulation cooling sliding vane rotary vacuum pump, to overcome the complex structure that existing cooling unit exists, cost cost height, the unfavorable shortcoming of cooling effect.
For reaching above-mentioned technical purpose, the technical solution adopted in the utility model is:
Sliding vane rotary vacuum pump is cooled off in a kind of circulation, comprises the housing 1 and the end cap 4 of pump, and it is characterized in that: described pump case 1 arranged outside has a frame 2; Be provided with the gap between described pump case 1 and the frame 2, be filled with cooling medium 3 in the gap.
Corresponding position, gap is provided with import 5 and outlet 6 between described end cap 4 and pump case 1 and the frame 2.
Described import 5 is arranged on the bottom of end cap 4, and outlet 6 is arranged on the top of end cap 4.
Be connected with intake pipe 7 and outlet pipe 8 respectively in the import 5 of described end cap 4 and the outlet 6.
Described intake pipe 7 is provided with modulating valve 9.
Described cooling medium 3 is a water.
The utility model with respect to the advantage of prior art is: simple in structure, the cost cost is low, implements good cooling results easily.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
The structural representation of the pump casing cover upper end cap that Fig. 2 is;
The 1-pump case, the 2-frame, the 3-cooling medium, the 4-end cap, the 5-import, the 6-outlet,
The 7-intake pipe, 8-outlet pipe, 9-modulating valve.
Five, embodiment:
Referring to Fig. 1, sliding vane rotary vacuum pump is cooled off in a kind of circulation, comprises the housing 1 and the end cap 4 of pump, and described pump case 1 arranged outside has a frame 2; Leave the gap between pump case 1 and the frame 2, be filled with cooling medium 3 in the gap.Described cooling medium 3 is generally water.Corresponding position, gap is provided with import 5 and outlet 6 between end cap 4 and the two housings.Import 5 is arranged on the bottom of end cap 4, and outlet 6 is arranged on the top of end cap 4.Be connected with intake pipe 7 and outlet pipe 8 respectively in import 5 and the outlet 6.During use, cold water is poured in the gap between the body of bivalve by the intake pipe 7 of end cap 4 bottoms, whole housing all is communicated with, and cold water heat during the absorption pump body running in double hulled gap becomes hot water, and hot water is flowed out by the outlet pipe 8 on end cap 4 tops again.The mobile heat when taking away pump housing work that can lean on circulating water like this is to reach the purpose of the cooling pump housing.On intake pipe 7, also be provided with modulating valve 9, can be according to the pump length of running time, and the temperature of the pump housing, regulate the flow of cold water, generally pump is remained at running about 35 ℃.
