Detailed Description
For better understanding of the objects, structure and function of the present invention, a compressor housing assembly and compressor of the present invention will be described in further detail with reference to the accompanying drawings of fig. 1-8.
As shown in fig. 1-5, a compressor housing device is designed, which takes a compressor as an example, and the main structure of the compressor housing device comprises a housing assembly 4, a stator 2 installed in the housing assembly 4, and a rotor 3 rotatably connected in the stator 2; the damping structure 5 is arranged in the shell component 4, the damping structure 5 is hung on the shell wall of the shell component 4 in a suspension mode, and when the shell component 4 vibrates, the damping structure 5 can move towards the opposite direction of the vibration of the shell component 4 to counteract the vibration energy. The structure is used on the compressor, when the compressor runs, energy can be consumed through the internal damping structure, the problem that the compressor vibrates greatly when the compressor runs at low frequency and high frequency is reduced, and the stability of the running work of the structure is improved.
The shell assembly 4 is internally provided with a suspension component, and the suspension component is connected between the damping structure 5 and the inner side wall of the shell assembly 4 and can freely move in space. The damping structure 5 is also suspended, and the suspension part comprises a first spherical hinge structure 41 movably connected with the side wall of the shell assembly 4, and a telescopic device connected with the other end of the first spherical hinge structure 41, wherein the telescopic device is preferably a telescopic connecting rod 42 in the embodiment, and the other end of the telescopic device is movably connected with the damping structure 5. One end of the telescopic link 42 away from the first spherical hinge structure 41 is movably connected to the damping structure 5 through a second spherical hinge structure 51.
The damping structure 5 is a flat plate-like or cap-like damping block 52. The damping mass 52 is free to vibrate in multiple directions within the interior, continuously dissipating vibrational energy generated from the housing assembly 4. When the shell assembly 4 operates at low frequency and high frequency, the vibration of the upper end of the shell assembly 4 is large, the telescopic connecting rod 42 can perform telescopic motion, and the damping block 52 moves in the opposite direction when the compressor vibrates, so that the energy is consumed, and the vibration of the compressor is reduced.
Furthermore, a damping mechanism is connected between the damping structure 5 and the shell component 4, and acts on the damping structure 5 through elastic telescopic internal stress, so that the jumping amplitude of the damping structure 5 is reduced; the preferred damping mechanism of this embodiment includes a spring positioning post 61 and a spring 62 sleeved on the spring positioning post 61.
In order to facilitate the disassembly and assembly, the top of the housing assembly 4 is designed as a detachable top cover assembly 6, wherein the spring positioning columns 61 are connected to the top cover assembly 6, and the top cover assembly 6 can be covered in the opening of the housing assembly 4 to realize a sealing connection. The upper cover assembly 6 is internally provided with a spring positioning column 61, a spring 62 is arranged on the spring positioning column 61, the spring 62 is pressed against the damping block 52, and the spring 62 is in a pressing state. When the compressor is in operation, the gas is discharged upwards, and the amplitude of the up-and-down jumping of the damping block 52 under the influence of the gas force is reduced. The spring 62 bears against the damping mass 52, and the spring 62 is in a compressed state. When the compressor is in operation, gas will be discharged upwards and will generate a force acting on the damping mass 52. The spring 62 prevents the damping block 52 from jumping up and down due to the influence of the gas force.
The compressor is provided, and the vibration of the compressor is reduced by the arrangement that when the compressor is operated, the compressor generates vibration, and the damping block 52 in the shell assembly 4 is operated in the opposite direction, so that the energy is counteracted. The compressor with the vibration damping structure 5 mainly comprises: the pump body subassembly 1, stator 2, rotor 3, casing subassembly 4, damping piece 5, upper cover subassembly 6, knockout part 7 etc.. The bottom of the inner cavity of the shell component 4 is connected with a pump body component 1, the input end of the pump body component 1 is in driving connection with the output end of the rotor 3, and the output end of the pump body component 1 is externally connected with a liquid distributor component 7 of the compressor. Pump body subassembly 1, stator 2, rotor 3 all set up in damping structure 5's below, and stator 2 and rotor 3 set up under damping structure 5, and when gaseous upwards discharge, damping structure 5 blocks along with the gaseous exhaust oil mass.
As shown in fig. 6, the damping structure 5 is a circular plate-shaped damping block 52, or another damping block 52 with a cover structure as shown in fig. 8, which improves the oil blocking effect, and the damping block 52 is disposed right above the rotor through-flow hole 31 of the rotor 3, which plays a role of blocking oil, and brings out the refrigeration oil to be compressed when blocking the exhaust, thereby improving the reliability of the compressor, and being beneficial to improving the energy efficiency of the system. The outer contour of the damping block 52 matches the outer contours of the rotor 3 and the stator 2, so that exhaust gas can be blocked, and the material size can be saved as much as possible.
As shown in fig. 7, when the gas is discharged upward, it is discharged together with a small amount of oil, which affects the reliability of the compressor and the system performance. The damping block 52 is arranged into a circular structure and is positioned right above the through flow hole of the rotor, and the outer diameter d1 and the outer diameter d2 of the rotor meet the following conditions: d1 is more than or equal to 0.8d2 and less than or equal to 1.1d2, and the height h1 between the damping block 52 and the stator 2 and the height h2 of the heat jacket of the stator 2 meet the following conditions: 0.5h2 is not less than h1 is not less than 0.6h2, when the gas is discharged upwards, a small part of oil is discharged together, the damping block 52 can effectively block the discharged oil above the through hole, and the problem that the oil is discharged together with the gas to cause the reliability problem and the energy efficiency reduction of the compressor is avoided. The vibration of compressor on the one hand in the work also can lead to the oil extraction volume to increase, if inside oil mass is too much along with the exhaust discharge, can lead to inside spare part lack of oil to cause some troubles such as wearing and tearing, can influence compressor life.
In consideration of the overall performance of the compressor, the oil blocking structure is designed by the research and development design, the damper formed by matching the damping structure 5 with other parts is designed into the oil blocking structure, the oil blocking structure is directly blocked above the stator 2 and the rotor 3, and the oil discharge rate of the compressor can be reduced. The problem that the compressor takes out the internal oil quantity when exhausting from the rotor through-flow hole 31, so that the lubrication of the compressor is poor and the reliability of the compressor is reduced is avoided. On the other hand, the oil quantity is prevented from entering the whole system, so that the heat exchange efficiency of the system is reduced, and the energy efficiency is reduced. The compressor with the structure has the advantages that the damper achieves dual purposes, and an oil retaining structure is not required to be additionally arranged, so that the technical effects of reducing parts and reducing the cost of producing the compressor are achieved.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes in the features and embodiments, or equivalent substitutions may be made therein by those skilled in the art without departing from the spirit and scope of the invention.
