The invention also provides the compressor of the magnet fixing device.
Description
Technical field
The present invention relates to compressor apparatus technical field, particularly a kind of compressor and magnet fixing device thereof.
Background technique
Compressor, in operation process, has the impurity such as iron powder or iron filings and produces, and these impurity may be followed refrigerant or refrigeration oil and be entered and require strict fit up gap, increase power consumption or cause damage parts; Also the impurity had can be followed refrigerant and be entered in system, systematic function can be caused to reduce even damage after accumulating over a long period.
In order to control and absorb the iron class impurity produced in compressor, the iron class impurity that existing compressor is used in adsorbed oil at lower cover position big city placement magnet, mode is various, have plenty of directly by magnet adsorption under cover, being then otherwise pressed in down by magnet of having covers, and these means of fixation have a bit not enough, be exactly magnet is not completely fixed, magnet can not be avoided to come off, if magnet is adsorbed onto on bent axle, then can reduce the performance and used life of compressor.
Summary of the invention
In order to be completely fixed by magnet, avoid magnet to come off, the invention provides a kind of magnet fixing device of compressor, to improve performance and the physical life of compressor.Present invention also offers a kind of compressor with magnet fixing device.
For achieving the above object, the invention provides following technological scheme:
A magnet fixing device for compressor, comprise lower cover, magnet fixing frame and magnet, magnet fixing frame is fixed on down and covers, and magnet is fixed between magnet fixing frame and lower cover, and magnet fixing frame also comprises the pressure head structure of restriction magnet positions;
Preferably, magnet fixing frame is the magnetic Metal plate of band;
Preferably, sheet metal structural comprises multiple corner;
Preferably, corner is 2;
Preferably, magnet adopt loop configuration, magnet by pressure head structure by being pressed on lower cover;
Preferably, pressure head structure is a bump, and bump is arranged on the annular space of magnet;
Preferably, the means of fixation of fixed magnet fixing frame is welding;
Preferably, fixing frame is positioned at lower cover marginal position;
Present invention also offers a kind of compressor, comprise the magnet fixing device of compressor, magnet fixing device is above-mentioned any one magnet fixing device, and this compressor is scroll compressor or rolling rotor type compressor.
As can be seen from above-mentioned technological scheme, magnet fixing device provided by the invention, effectively can control and absorb the iron class impurity produced in compressor, due to the full encirclement sheet metal structural that magnet fixing frame adopts corner many, magnet adopts loop configuration, the more structure in these corners is all conducive to increasing magnet adsorption ability and adsorption area, improves performance and the physical life of compressor.
Present invention also offers a kind of compressor with above-mentioned magnet fixing device.Because above-mentioned magnet fixing device has above-mentioned technique effect, the compressor with above-mentioned magnet fixing device also should have same technique effect, introduces no longer one by one at this.

Embodiment
This embodiment provides a kind of magnet fixing device of compressor, and it is better that it inhales magnetic bits effect.This embodiment additionally provides a kind of compressor comprising above-mentioned magnet fixing device.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 2, the magnet fixing device of compressor of the present invention, comprise magnet fixing frame 10, magnet 11, lower cover 12, magnet fixing frame also comprises pressure head 13, magnet fixing frame 10 is fixed on lower cover 12, as shown in Figure 3, magnet fixing frame 10 and lower cover 12 are fixed by the means of fixation of welding, magnet fixing frame 10 selects Metal plate, magnet fixing frame 10 generally has two corners, magnet fixing frame 10 is generally welded on the edge near lower cover 12, so just do not worry that bent axle and the possible contact of magnet fixing frame can bring unnecessary trouble, magnet 11 is annular, be arranged on the space that magnet fixing frame 10 and lower cover 12 surround, the annular space of magnet 11 is pushed down by the pressure head 13 on magnet fixing frame 10, magnet 11 and lower cover 12 are fixed together by magnetic force, simultaneously because the position-limiting action of magnet fixing frame 10 further secures the position of magnet 11, pressure head 13 on magnet fixing frame 10 is by pushing down the annular space of magnet 11, equally further define the position of magnet 11, this ensure that the fixing of magnet, because magnet fixing frame 10 is Metal plate, due to the magnetization of magnet 11, magnet fixing frame 10 not only increases the adsorption area of iron filings, the edge edge of its corner and ring magnet 11 has stronger magnetic simultaneously, these favourable permanent and iron filings in a large amount of absorption refrigeration oil, as shown in Figure 4, pressure head 13 is a bump, and in certain gradient, be generally 1 °-5 °, in the present embodiment the gradient of bump be 5 ° to ensure that pressure head 13 can be placed in the annular space of magnet 11.
The embodiment of the present invention additionally provides a kind of compressor, comprises magnet fixing device, and magnet fixing device is any one magnet fixing device above-mentioned.Because above-mentioned magnet fixing device has above-mentioned technique effect, the compressor with this magnet fixing device also should have same technique effect, introduces no longer one by one at this.
