When exhaust hood 40 is two, one of them can be arranged on main bearing 21, and wherein another can be arranged on supplementary bearing 23.Now, exhaust cavity 401 can be made up of main exhaust chamber and secondary exhaust cavity two-part, main bearing 21 and an exhaust hood 40 can limit main exhaust chamber, supplementary bearing 23 and another exhaust hood 40 can form secondary exhaust cavity, main bearing 21 and supplementary bearing 23 can arrange relief opening 202 respectively, and exhaust effect is better.Now, exhaust hood 40 can arrange thermal-protective coating 50, or the side surface towards exhaust cavity 401 of main bearing 21 and the side towards exhaust cavity 401 of supplementary bearing 23 can arrange thermal-protective coating 50 on the surface.
Wherein, when exhaust hood 40 is two, the structure of two exhaust hoods 40 can be identical, also can be different, can arrange as required.Such as, in Fig. 3 shown in the different structure that is with the exhaust hood 40 shown in Fig. 4 of exhaust hood 40, two kinds of structures all can arrange thermal-protective coating 50.
As shown in Figure 1, cylinder 22 can be provided with the exhaust passage 203 be communicated with exhaust cavity 401, one end of outlet pipe 14 is stretched in exhaust passage 203.Gas in exhaust cavity 401 can be flow in outlet pipe 14 by exhaust passage 203.Wherein, exhaust passage 203 can be communicated with exhaust cavity 401 by the through hole on main bearing 21 or supplementary bearing 23.As shown in Figure 1, the through hole on supplementary bearing 23 is communicated with exhaust passage 203 and exhaust cavity 401, makes exhaust passage 203 realize being communicated with exhaust cavity 401.
According to some embodiments of the present invention, at least one thermal-protective material being less than or equal to 1W/ (mk) by thermal conductivity in main bearing 21 and supplementary bearing 23 is made.Thus, main bearing 21 and supplementary bearing 23 can have good heat-shielding performance, effectively prevent heat in exhaust cavity 401 to compressing mechanism and air-breathing transmission, ensure the service behaviour of compressor 100.
Alternatively, the thermal-protective material that exhaust hood 40 can be less than or equal to 1W/ (mk) by thermal conductivity is made.Thus, exhaust hood 40 can have good effect of heat insulation.Now, exhaust hood 40 is whole can form a thermal-protective coating 50, and effect of heat insulation is very good, and exhaust hood 40 is convenient to manufacture.
Wherein, the thermal-protective material that thermal conductivity is less than or equal to 1W/ (mk) is known material, is understandable for a person skilled in the art, no longer illustrates at this.
In embodiments more of the present invention, exhaust hood 40 can be formed as one part.Thus, exhaust hood 40 is easily manufactured, and cost is low, and intensity is high, is convenient to install and good heat-insulation effect.
