Abstract
The invention relates to the technical field of vacuum pressure combination pumps, in particular to a pump body of a vacuum pressure combination pump. The pump body comprises a hollow-circular-tube-shaped pump shell. A front installation base and a back installation base which are communicated with the pump shell are arranged on the front end face and the back end face of the pump shell respectively. A plurality of upper sound absorption strips are arranged at the upper end of the front installation base, the upper end of the back installation base and the upper surface of the pump body, a plurality of lower sound absorption strips are arranged at the lower end of the front installation base, the lower end of the back installation base and the lower surface of the pump body, and the positions of the upper sound absorption strips correspond to the positions of the lower sound absorption strips. The circle centers of circles formed by the multiple upper sound absorption strips and the multiple lower sound absorption strips are first circle centers, the circle center of the pump shell is a second circle center, and the first circle centers are located above the second circle center. An air sucking hole communicated with the front installation base is formed in an opening of the front installation base, and an air outlet hole communicated with the back installation base is formed above the portion behind the air sucking hole. According to the pump body of the vacuum pressure combination pump, noise generated during working is small, and the whole working environment of the air pump is optimized.
Description
Technical field
The present invention relates to the technical field of vacuum pressure combined pump, especially a kind of vacuum pressure combined pump pump housing.
Background technique
Air compressor is the device mechanical energy of prime mover being converted to gas pressure energy, is compressed-air actuated pressure generator.The kind of air compressor is a lot, and vacuum pressure combined pump is exactly one of them very typical type.Sliding-vane air compressor is positive displacement compressor, compares with piston type air compressor, and it is not inhaled, outlet valve and crankshaft rod structure, and therefore, the rotating speed of sliding-vane air compressor is higher, directly can be connected with original motor, and Comparision is tranquil.
The part but existing sliding-vane air compressor still comes with some shortcomings technically, impurity in air is brought in compressor by existing sliding-vane air compressor Chang Yinwei in air compressing process, cause some component in compressor can not normally run, have impact on the working efficiency of compressor.Meanwhile, existing sliding-vane air compressor can produce very large noise in air-breathing or exhaust process, has had a strong impact on the whole working environment of compressor.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposed in above-mentioned background technology, and the invention provides a kind of vacuum pressure combined pump pump housing, the noise produced during work is less, optimizes the whole working environment of air pump.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vacuum pressure combined pump pump housing, comprise the pump case of hollow round tubular, before pump case, ear end face is respectively arranged with the front fitting seat and rear fitting seat that are connected with pump case, front fitting seat and rear fitting seat upper, lower end and pump housing upper surface are respectively arranged with the corresponding upper sound-absorbing bar in multiple position and lower sound-absorbing bar with pump housing lower surface, the center of circle of the circle that multiple upper sound-absorbing bar and multiple lower sound-absorbing bar are formed is first center of circle, the center of circle of pump case is second center of circle, first center of circle is positioned at the top in second center of circle, the opening of front fitting seat is provided with the suction port be connected with front fitting seat, the back upper place of suction port offers the exhaust port be connected with rear fitting seat.
In order to make air pump have good air-breathing and exhaust effect, therefore the shape of suction port is kidney-shaped, and the shape of exhaust port is rectangular.
In order to make the process of air-breathing and exhaust more smooth and easy, therefore between suction port and exhaust port, the angle of angle is 100 ° ~ 160 °.
Beneficial effect of the present invention: this kind of vacuum pressure combined pump pump housing, by arranging multiple sound-absorbing bar on pump case, and multiple sound-absorbing bar become the center of circle of the center of circle and pump case to offset from each other certain position, the noise that air pump of bowing is operationally produced is less, optimizes the whole working environment of air pump.

Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of vacuum pressure combined pump pump housing as depicted in figs. 1 and 2, comprise the pump case 1 of hollow round tubular, before pump case 1, ear end face is respectively arranged with to be connected with pump case 1 front fitting seat 2 and rear fitting seat 3, front fitting seat 2 and rear fitting seat 3 upper, lower end, the pump housing 1 upper surface and the pump housing 1 lower surface are respectively arranged with the corresponding upper sound-absorbing bar 4 in multiple position and lower sound-absorbing bar 5, the height being positioned at the upper sound-absorbing bar 4 of front fitting seat 2 upper end portion is consistent with the height of the lower sound-absorbing bar 5 being positioned at rear fitting seat 3 underpart, the height being positioned at the upper sound-absorbing bar 4 on the pump housing 1 upper surface is greater than the height of the lower sound-absorbing bar 5 be positioned on the pump housing 1 lower surface.
The center of circle of the circle that multiple upper sound-absorbing bar 4 and multiple lower sound-absorbing bar 5 are formed is the first center of circle A, the center of circle of pump case 1 is the second center of circle B, first center of circle A is positioned at the top of the second center of circle B, the opening of front fitting seat 2 is provided with the suction port 6 be connected with front fitting seat 2, and the back upper place of suction port 6 offers the exhaust port 7 be connected with rear fitting seat 3.
Wherein, the shape of suction port 6 is kidney-shaped, and the shape of exhaust port 7 is rectangular, makes air pump have good air-breathing and exhaust effect.Between suction port 6 and exhaust port 7, the angle of angle is 100 ° ~ 160 °, makes the process of air-breathing and exhaust more smooth and easy.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
