Abstract
The utility model discloses a pump body of a rotor air compressor for an air-conditioner, which can prevent the deformation of hole for connection with an upper flange and a lower flange on an air cylinder. The pump body comprises an upper flange, an air cylinder and a lower flange; a plate body of the upper flange is provided with at least two upper flange threaded holes uniformly distributed along the circumferential direction of the plate body and at least four upper flange through holes uniformly distributed along the circumferential direction of the plate body; the air cylinder is provided with upper flange connection through holes corresponding to the upper flange threaded holes and transition through holes corresponding to the upper flange through holes, the upper flange connection through holes are counter bores, and the lower flange is provided with lower flange connection through holes corresponding to the transition through holes; the upper flange is connected with the air cylinder through the upper flange threaded holes, the upper flange connection through holes and upper flange connection bolts, and the lower flange is connected with the air cylinder through the upper flange through holes, the transition through holes, the lower flange connection holes and lower flange connectors. Based on the structure, the running stability of the pump body is improved, the input power of the air compressor is reduced, and the purpose of improving the performance of the entire machine is achieved.
Description
Technical field
The utility model relates to a kind of pump housing, relates in particular to a kind of pump housing of idle call rotor-type compressor.
Background technique
The pump housing of idle call rotor-type compressor of the prior art is generally lower flange through hole is set when equipment, tapped hole is set on the cylinder, by bolt upper lower flange is linked to each other with cylinder.But this structure has the following disadvantages: behind bolt-locking, because the inwall that the screw thread discontinuity on the cylinder causes cylinder tapping place is to inner process, thereby affect pump housing smooth operation, increase running resistance, increase the Energy Efficiency Ratio reduction so that compressor enters power.When cylinder deformation is larger, even might directly cause stall.
The model utility content
The technical problem that the utility model solves provides the pump housing of the idle call rotor-type compressor that a kind of hole that prevents from being used for being connected with upper flange and lower flange on the cylinder deforms.
The technological scheme that its technical problem that solves the utility model adopts is: the pump housing of idle call rotor-type compressor, comprise upper flange, cylinder and lower flange, be provided with on the disk body of upper flange at least 2 along disk body circumferentially uniform upper flange tapped hole and at least 4 along the circumferential uniform upper flange through hole of disk body, be provided with on the cylinder with the upper flange tapped hole one to one the upper flange connecting through hole and with upper flange through hole transition through hole one to one, described upper flange connecting through hole is counterbore, is provided with on the lower flange and transition through hole lower flange attachment hole one to one; Upper flange links to each other with cylinder by upper flange tapped hole, upper flange connecting through hole and upper flange connecting bolt, and lower flange links to each other with cylinder by upper flange through hole, transition through hole, lower flange attachment hole and lower flange link.
Further be: described lower flange attachment hole is the lower flange connecting through hole, and described lower flange link comprises lower flange connecting bolt and lower flange attaching nut.
Further be: described lower flange attachment hole is lower flange connecting thread hole, and described lower flange link comprises the lower flange connecting bolt.
The beneficial effects of the utility model are: the hole of having avoided being used on the cylinder being connected with upper flange and lower flange deforms, and has improved the smoothness of operation of the pump housing, has reduced the power that enters of compressor, thereby reaches the purpose that improves overall performance.
Description of drawings
Fig. 1 is the corresponding relation schematic diagram between the respective aperture on upper flange, cylinder and the lower flange;
Fig. 2 is that the lower flange attachment hole is the assembling schematic diagram in lower flange connecting thread hole;
Fig. 3 is that the lower flange attachment hole is the assembling schematic diagram of lower flange connecting through hole;
Be labeled as among the figure: lower flange 1, cylinder 2, upper flange 3, disk body 4, upper flange connecting through hole 5, upper flange tapped hole 6, lower flange attachment hole 7, transition through hole 8, upper flange through hole 9, upper flange connecting bolt 10, lower flange connecting bolt 11, lower flange attaching nut 12.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figure 1 to Figure 3, the pump housing of idle call rotor-type compressor, comprise upper flange 3, cylinder 2 and lower flange 1, be provided with on the disk body 4 of upper flange 3 at least 2 along disk body circumferentially uniform upper flange tapped hole 6 and at least 4 along the circumferential uniform upper flange through hole 9 of disk body, be provided with on the cylinder 2 with the upper flange tapped hole one to one upper flange connecting through hole 5 and with upper flange through hole transition through hole 8 one to one, described upper flange connecting through hole 5 is counterbore, is provided with on the lower flange 1 and transition through hole lower flange attachment hole 7 one to one; Upper flange 3 links to each other with cylinder 2 by upper flange tapped hole 6, upper flange connecting through hole 5 and upper flange connecting bolt 10, and lower flange 1 links to each other with cylinder 2 by upper flange through hole 9, transition through hole 8, lower flange attachment hole 7 and lower flange link.When flange connecting hole 7 was the lower flange connecting through hole instantly, described lower flange link comprised lower flange connecting bolt 11 and lower flange attaching nut 12.During installation, lower flange connecting bolt 11 passes upper flange through hole 9, transition through hole 8, lower flange attachment hole 7 and fastening by lower flange attaching nut 12 successively.When flange connecting hole 7 was lower flange connecting thread hole instantly, described lower flange link comprised lower flange connecting bolt 11.During installation, lower flange connecting bolt 11 passes upper flange through hole 9 and transition through hole 8 successively, and fastening by lower flange attachment hole 7.
Transition through hole 8 on the cylinder 2 and upper flange connecting through hole 5 all are through hole, and said structure has been avoided tapping on cylinder 2,2 pressure that are subjected to lower flange of cylinder, and pressure distribution is even, and the hole of lower flange deforms can not cause being used for connecting upward on the cylinder.
