Therefore, the foot pad 1 for the compressor according to the embodiment of the present invention has advantages of convenience in use, convenience in transportation of the compressor, convenience in reducing the operating noise of the compressor, and the like.

A foot pad 1 for a compressor according to an embodiment of the present invention will be described with reference to the accompanying drawings.

In some embodiments of the present invention, as shown in fig. 1 to 2, a foot pad 1 for a compressor according to an embodiment of the present invention includes a stopper 100 and a support pad 200.

In some embodiments of the invention, as shown in fig. 1, the support pad 200 has a deformable section 210 between the stop 120 and the chassis 110, the deformable section 210 having a dimension in the longitudinal direction when the support pad 200 is in the first state that is greater than a dimension of the support pad 200 in the second state. So be convenient for make supporting pad 200 switch between first state and second state, guarantee the compressor at the structural stability of transportation, guarantee the compressor at the operational reliability of working process.

Specifically, as shown in fig. 1, the deformable section 210 has a receiving cavity 211 therein, and the receiving cavity 211 is filled with a phase-change medium. This may allow for a change in the dimension of the deformable section 210 in the longitudinal direction using the phase change medium, thereby changing the fit between the support pad 200 and the stop 120.

Specifically, the receiving cavity 211 is a closed cavity and extends along the circumferential direction of the support pad 200. The accommodating cavity 211 may be plural, and the plural accommodating cavities 211 are arranged at intervals along the longitudinal direction. The thickness between the inner peripheral wall of the receiving cavity 211 and the outer peripheral wall of the support pad 200 is greater than or equal to 1 mm and less than or equal to 3 mm.

It is to be understood here that the phase change medium is a material which is solid at normal temperature and can be melted after reaching a predetermined temperature. Of course, the material filled in the accommodating cavity 211 may also be a non-phase-change medium, that is, a material which is solid at normal temperature and gradually melts or softens after reaching a certain temperature, such as paraffin or an asphalt mixture.

Optionally, the inner wall of the receiving cavity 211 may be provided with an anti-corrosion layer to isolate the support pad 200 from the phase change medium in the receiving cavity 211. This may prevent the phase change medium from melting or corroding with the material of the support mat 200.

Optionally, as shown in fig. 1, the support pad 200 also has a compressor support location 220, the compressor support location 220 being adjacent to the stop 120, and the deformable section 210 being adjacent to the compressor support location 220. This not only facilitates the attachment of the compressor to the support pad 200 so that the compressor is supported on the support pad 200, but also facilitates the transfer of the weight of the body of the compressor and the heat generated during operation of the compressor to the transformable segment 210 so that the transformable segment 210 can be switched over according to the change in temperature.

Specifically, the compressor support 220 is parallel to the machine leg 2 of the compressor. This facilitates the stable support of the foot 2 on the support pad 200.

Further, as shown in fig. 1, the supporting pad 200 is further provided with a notch 230, and the deformable section 210 is located between the notch 230 and the compressor supporting location 220. The setting of the flexible section 210 of not only being convenient for like this, be convenient for increase the shock-absorbing capacity of supporting pad 200 moreover, reduce the vibration range of compressor, reduce the operating noise of compressor.

Specifically, the notches 230 are annular openings and extend along the circumferential direction of the support pad 200, and the notches 230 may be plural and arranged at intervals in the longitudinal direction.

In some embodiments of the present invention, the support cushion 200 is configured to switch from the first state to the second state when the ambient temperature is greater than a predetermined temperature. Because the compressor is in a normal temperature state during transportation, and the temperature of the compressor is higher during operation, for example, the temperature of the compressor during transportation can be 20 degrees centigrade, and the operating temperature of the compressor during operation can reach 70 degrees centigrade. Thus, by setting a suitable predetermined temperature, the support pad 200 can be automatically switched to the operating state according to the change of the temperature. The medium in the holding chamber 211 takes place the melting or softens after reaching the uniform temperature promptly, and the elastic modulus of supporting pad 200 reduces, and supporting pad 200 takes place slightly to subside under the action of gravity of the fuselage of compressor, makes and produces the clearance between supporting pad 200 and the backstop portion 120 to can save the process of dismouting callus on the sole 1, simplify operating personnel's operation process, when shortening the installation of compressor, improve the complete machine performance of compressor.

Specifically, the predetermined temperature is in the range of 65 ℃ to 85 ℃. Can guarantee in the transportation of compressor like this that supporting pad 200 is in first state, structural reliability when improving the compressor transportation guarantees that supporting pad 200 is in the second state in the course of the work of compressor, reduces the operating noise of compressor.

It should be understood that, after the compressor is shut down for the first time, the temperature of the compressor returns to normal temperature, the medium in the accommodating chamber 211 gradually loses the capability of resisting shear deformation due to melting or softening under the first high-temperature working condition, so that radial expansion and axial compression occur, the weight of the body of the compressor cannot be resisted only by the sidewall on the periphery of the accommodating chamber 211, the medium in the accommodating chamber 211 cannot rebound, and a permanent gap is generated between the supporting pad 200 and the stopping portion 120.

Optionally, as shown in fig. 1, the limiting portion 100 further includes a central pillar 130, the central pillar 130 extends along the longitudinal direction, the chassis 110 and the stopping portion 120 are connected to the central pillar 130, and the supporting pad 200 is sleeved on the outer periphery of the central pillar 130. This not only facilitates the installation of the chassis 110 and the stopper 120, but also can position and guide the supporting pad 200 by using the center post 130, facilitating the smooth installation of the supporting pad 200.

Further, as shown in fig. 1, the inner circumferential surface of the support pad 200 is configured in a form that both ends in the longitudinal direction are narrow and the middle portion is wide, both ends of the support pad 200 are fitted over the center pillar 130, and the middle portion of the support pad 200 is spaced apart from the center pillar 130 to form the buffer chamber 131. This further facilitates the improvement of the vibration-damping and cushioning performance of the support pad 200, and facilitates the reduction of the operating noise of the compressor.
