Abstract
The present invention belongs to the field of compressor, and is one kind welded unit for the compression part of sealed rotary compressor. Several indirect welded parts are used to fix the compression pump casing onto the chassis of the sealed container. The compression pump casing consists of cylinder installed below the sealed container, upper main bearing and lower auxiliary bearing fixed to the cylinder. Each of the indirect welded parts has its one side screwed to the lower screw hole of the cylinder and the other side welded to the chassis of the sealed container. This way can eliminate welding produced part deformation, reduce the rotating friction of inner parts of the compressor, raise the compression efficiency of refrigerant, prolong the service life of the compressor and raise reliability.
Description
Technical field
The invention belongs to compressor field and be invention about the soldering installation of hermetic rotary compressor press part.It minimizes the distortion of the parts that cause because of welding, and improves compression performance by the welded structure of change support press part.
Background technique
Generally speaking, hermetic rotary compressor is by the cylinder body that is fixed on as the cabinet inside of seal container, main bearing and auxiliary bearing are fixed on the compressor pump casing that forms on the upper and lower part of cylinder body, the compression volume that on the inboard of compressor pump casing, has compression refrigerant gas, and this cylinder body is fixed on the cabinet with welding manner.But because cylinder body directly is weldingly fixed on the cabinet, so has parts portion easy deformation, the problem that compression performance descends.
Fig. 1 is the part profile diagram of hermetic rotary compressor that utilizes the soldering installation of old-fashioned press part.Fig. 2 is the cross-section profile of hermetic rotary compressor that utilizes the soldering installation of old-fashioned press part.As depicted in figs. 1 and 2, the inside of seal container (1) is equipped with the motor (4) that is formed by rotor (2) and stator (3), and running shaft (5) is pressed into, be fixed on and be positioned on the axis hole (2a) above-mentioned rotor (2) center, that form by Vertical direction.
Be formed with whole eccentric part (6) on the underpart of above-mentioned running shaft (5), be inserted with rolling ring (7) on the outside of its eccentric part (6), and the compression mechanical part (12) that is formed by cylinder body (9) and upper and lower part bearing (10) (11) is installed, when its rolling ring (7) forms the compression volume (8) of compression refrigerant when being rotated.
The outlet side of going up portal (10a) that form at above-mentioned upper bearing (10) is equipped with valve assembly body (15), is equipped with on the top of its valve assembly body (15) to reduce the baffler (16) of discharging noise.
On suction port (9a) side of above-mentioned cylinder body (9), be communicated with the storage (17) that is mounted with the inflow that prevents liquid coolant, the discharge tube (18) that compressed high pressure refrigerant gas in compression mechanical part (12) is discharged to the outside is installed above the above-mentioned seal container (1).
If power supply is connected on the old-fashioned hermetic rotary compressor that as above constitutes, the rotor (2) of motor (4) is just be rotated, and its running shaft (5) that is pressed in the rotor (2) also is rotated.
The eccentric part (6) that forms on the underpart of running shaft (5), be rotated with the rolling ring (7) that is combined on its eccentric part (6), by the suction port (9a) of cylinder body (9), be the compressing refrigerant gas that is inhaled into the inner low-temp low-pressure state of compression volume (8) cold media air of high-temperature high-pressure state.
As above compressed cold media air is discharged from by valve assembly body (15), so that discharge to the inside of seal container (1) by the hole (16a) of passing through of baffler (16).The cold media air of the High Temperature High Pressure that so is discharged from is discharged to the outside through the slit between rotor (2) and the stator (3) by discharge tube (18).
At this moment, blade (20) carries out back and forth movement according to spring (21) in cylinder body (9) bore portion, and snugly fits into rolling ring (7) and go up to form press part, and rolling ring (7) also according to the rotatablely moving of running shaft (5), is rotated motion in cylinder body (9) inside.
The as above old-fashioned hermetic rotary compressor of Gou Chenging, its seal container (1) is the upper cap (1b) that utilizes cabinet (1a) and the sealed formation of lower cover (1c), for supporting compression volume, directly weld from cabinet (1a) outside at three points, the distortion that 3 spot welding of press part are produced, as using shown in the arrow among Fig. 2, because of the bore direction to cylinder body (9) internal diameter direction and cylinder body (9) directly adds welding heat, the position of its distortion is cylinder body (9) bore portion and inner-diameter portion whose.
So, in old-fashioned hermetic rotary compressor, as welding rear-bank rotor housing (9) bore portion and inner-diameter portion whose, with the section position of main bearing (10), the distortion that these positions produce gives the effectiveness affects of press part very big.
Old-fashioned hermetic rotary compressor as described above, if cylinder body is welded on the cabinet, it directly can produce the welding heat distortion in the position of contact, and the position of generation thermal distortion can cause the distortion at cylinder body bore, internal diameter position.The bore portion of cylinder body is the position of carrying out back and forth movement according to blade, and when it is out of shape when serious, the leakage that can produce cold media air is rushed down, and pressure rises, the anomaly of abnormal sound etc.
In addition, because thermal distortion, its long-term credibility can be subjected to very big harmful effect, because the phenomenon of the lost of life of the inordinate wear phenomenon of this meeting production part and product.
Particularly, because the bore portion of cylinder body and blade position are the positions that is easy to generate wear phenomenon in hermetic rotary compressor most, so become the credible principal element that descends of product.
Summary of the invention
The present invention proposes in order to solve above-mentioned problem in the past, not its objective is and directly the compressor pump casing that the refrigerant compression volume is provided is welded on the cabinet, but by utilizing indirect weld assembly, connect in indirect mode, so that make the soldering installation of the press part that welds the minimized hermetic rotary compressor of part distortion that causes.
In order to achieve the above object, according to the soldering installation of the press part of hermetic rotary compressor of the present invention, the hermetic rotary compressor that will possess the refrigerant compression volume is arranged on the inside of seal container.For the compressor pump casing that above-mentioned refrigerant compression volume is possessed is fixed on the cabinet of above-mentioned seal container, earlier above-mentioned compressor pump casing and several indirect weld assemblies is fixed, and above-mentioned indirect weld assembly is welded on the above-mentioned cabinet.
Above-mentioned compressor pump casing is to be made of the cylinder body of the inboard that is installed in above-mentioned seal container and the main bearing and the auxiliary bearing that are fixed on the upper and lower part of above-mentioned cylinder body, sidepiece of above-mentioned indirect weld assembly is by being bolted to above-mentioned cylinder body downside, and other sidepieces are welded on the cabinet of seal container and constitute.
Advantage and good effect
As mentioned above, the press part soldering installation of hermetic rotary compressor, not directly to be weldingly fixed on the compressor pump casing on the cabinet, but utilize indirect weld assembly, heat is impacted in the welding that directly is communicated to pressing chamber ease down to minimized indirect mode, the part distortion that welding is caused is reduced to bottom line.Like this, the compression friction so can improve the compression efficiency of refrigerant, also can reduce noise simultaneously when the parts that will reduce compressor inside rotatablely moved.Because possess these advantages, thereby can reach the life-span of raising product and the effect of reliability and value.
