Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
In conjunction with Fig. 1 to Fig. 3, a kind of new type of compression machine cap improving pulse number, the one end including main annular sidewall 1 and top board 2, the edge of top board 2 and main annular sidewall 1 is fixedly connected into one, and top board 2 is outwardly spherical shell shape structure.Described main annular sidewall 1, away from the other end of top board 2, is connected to secondary annular sidewall 5 by annular connecting portion 4, and main annular sidewall 1 is fixedly connected into one with secondary annular sidewall 5 by annular connecting portion 4.The internal diameter of described secondary annular sidewall 5 is more than the internal diameter of main annular sidewall 1, and secondary annular sidewall 5 can be socketed in the outside of the upper end of compressor housing, and secondary annular sidewall 5, away from one end of annular connecting portion 4, can weld together with the outer wall of compressor housing.Described secondary annular sidewall 5 is on the inwall of one end of annular connecting portion 4, it is provided with three locating pieces 6 ringwise, in described three locating pieces 6 are generally aligned in the same plane, time this top cover and compressor housing are assembled together, the upper surface of compressor housing withstands on the axis coaxle of axis and the compressor housing ensureing secondary annular sidewall 5 on three locating pieces 6, it is achieved quickly position.
The side at described top board 2 position at its center has the mounting seat 7 being stamped and formed out laterally; the surface of mounting seat 7 is outwardly; higher than the outer surface of top board 2, the inner side of mounting seat 7 forms the accommodation chamber of recess relative to top board 2, and holding intracavity can built-in protector.The top of mounting seat 7 has the electric connection pilot hole 8 for welding electric connection, and electric connection is positioned at electric connection pilot hole 8, and the edge of the sidewall of electric connection and electric connection pilot hole 8 welds together.It is plane that the upper surface of described mounting seat 7 is positioned at the peripheral part of electric connection pilot hole 8; the plane at mounting seat 7 top and the end face of main annular sidewall 1 are the angle of 3 °～7 °; owing to top board 2 is spherical shell shape structure; inner space corresponding in the middle part of top board 2 is bigger, and protector is that certain inclination angle is arranged on inside top cover.The opposite side at top board 2 position at its center has the escape pipe installing hole 9 installing escape pipe, and top board 2 is positioned at the peripheral part of escape pipe installing hole 9, for the circular groove being stamped and formed out to the inner side of top board 2.Escape pipe is positioned at escape pipe installing hole 9, and its one end communicates with the inside of top cover, and the other end stretches out the outside of top board 2, and the outer wall of described escape pipe is integral with the sidewall weld of trachea installing hole 9.
This Novel top cap is arranged on the upper end of compressor case, and by integrally welded with the outer wall of compressor case for the bottom of secondary annular sidewall 5.Compressor is in the course of the work, pumping expellant gas enters into casing internal, gases at high pressure it are full of in casing, gases at high pressure in casing are discharged by the escape pipe being arranged in escape pipe installing hole 9, gases at high pressure in casing are pulsed, the stress that top cover is continually changing, makes the middle part of top board 2 to externally-generated periodic deformation.The top board 2 of this Novel top cap adopts chondritic, the pressure distribution within top board 2 can being made more uniform, reduce the stress that the core of top board 2 bears, the core pressure experienced of top board 2 diminishes, meanwhile, the middle part of top board 2 is to externally-generated periodic deformation.For 35Frame Rotary Compressor, contrast through CAE simulation analysis, the top cover of the top cover newer type of conventional flat-top, when equal pulse testing, the maximum position of the former stress is in the middle, the maximum pressure born is 714.8MPa, also in the middle, the maximum pressure born is 221.5MPa at the latter's stress maximum position, finds to adopt the Novel top cap of spherical shell shape by contrast, subjected to stress substantially reduces, and the ability that opposing destroys increases exponentially.Above-mentioned pulse testing also finds, the maximum distortion occurred in the middle part of the former is 0.547mm, and the maximum distortion occurred in the middle part of the latter is 0.073mm, the deformation that novel top cover produces in the course of the work is less, and in actual tests result, the pulse testing number of times of the former relatively the latter is high more than about 100,000 times.Visible, new ball-type top cover greatly improves the pulse testing number of times of existing Conventional press, enhances safety and service life that compressor uses.
The top board of compressor top cover is designed to spherical structure by the present invention, the top cover of spherical structure is relative to the top cover of flat-tope structure, it is subject to its internal pulsating pressure and is distributed to peripheral part, no longer excessively focus on the core of top cover, the maximum stress being subject in the middle part of the top board of spherical structure diminishes, the maximum displacement produced because of stress in the middle part of top board also diminishes, it is to avoid top cover bursts.The compressor of the top cover of configuration spherical structure, it is possible to bearing the pulsating pressure of more number of times, security performance and the service life of top cover are greatly improved.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, the change made in the essential scope of the present invention of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
