In this integrated molding, the adjusting slider 122, the mounting guide 21 and the sliding guide 23 may be collectively referred to as an adjusting member, and as shown in fig. 1, the adjusting member includes three parts, namely, the mounting guide 21, the adjusting slider 122 and the sliding guide 23.
The adjusting slider between the mounting guide rod 21 and the sliding guide rod 23 is used as an adjusting part 22 which forms a complete cylinder with the cylinder block, as shown in the schematic front end face of the adjusting slider in fig. 3, an end face 33 at the bottom of the adjusting part is an arc surface, the arc surface preferably has the same circle center and the same radius as the arc surface of the inner wall surface of the cylinder hole of the compressor, and the width of the adjusting part is the same as the width of the adjusting groove of the cylinder block.

The mounting guide rod is preferably integrally formed with the adjusting slider 122 and extends from the front end face of the adjusting slider, the cylinder head is provided with a corresponding guide portion 61, and the mounting guide rod is matched with the guide portion of the cylinder head to limit the horizontal and vertical positions of the adjusting slider 122. Specifically, as shown in fig. 6, the front end surface 24 of the cylinder head, the guiding portion is formed with an inward concave limiting end surface and a mounting hole further recessed in the limiting end surface on one side facing the cylinder hole, the mounting guide rod and the end of the guiding portion matched with each other are inserted into the mounting hole, the length of the preferable mounting guide rod is smaller than or equal to the depth of the mounting hole, the diameter of the mounting guide rod is equal to the aperture of the mounting hole, so that the mounting hole 62 can be used for limiting the horizontal and vertical positions of the mounting guide rod 21 of the adjusting slider, and further limiting the positions of the adjusting slider in two directions, so that the adjusting slider can only slide along the axial direction. And the guide part has the function of restricting the maximum position of the adjusting slide block advancing in the axial direction, and when the adjusting slide block moves to the position that the front end surface is overlapped with the plane of the guide part along the axial direction, the adjusting slide block advances to the maximum axial position.
The sliding guide rod is positioned at the tail part of the adjusting slide block, namely on the rear end face of the adjusting slide block, the sliding guide rod is matched with the linear motor 121, and the linear motor 121 is fixed above the cylinder seat through a screw. Preferably, the sliding guide is also integrally formed with the adjustment slider. The slide guide rod is internally provided with a shaft hole for mounting the magnetic shaft block 54 so as to realize driving connection with the linear motor. Further preferably, as shown in the schematic sectional view of the left side view of the adjusting slider in fig. 4, the outer diameter of the sliding guide rod 23 is equal to the inner diameter of the fitting hole on the linear motor. The adjusting slide block is arranged behind the compressor, is connected with the linear motor through the sliding guide rod and implements volume adjusting work, and the linear motor can change the position of the sliding guide rod in the axial direction, so that the adjusting slide block moves back and forth to achieve the purpose of adjusting the effective volume of the cylinder. Therefore, the refrigerating capacity of the compressor is changed, the displacement of the compressor is changed under the high-performance running frequency state of the compressor, and the performance of the compressor under the low refrigerating capacity state is improved.
Specifically, the adjustment process is exemplified as follows, and can be divided into two steps S1 and S2:
and S1, controlling the movement of the adjusting slide block by the linear motor.
The linear motor changes the position of the adjusting slide block in the axial direction by pushing in/pulling back the sliding guide rod. When the position where the front end surface of the adjustment part of the index adjustment slider coincides with the front end surface of the cylinder head is P1 and the position where the front end surface of the adjustment part of the index adjustment slider coincides with the plane of the cylinder head guide part is P2, the range of movement of the front end surface of the adjustment part of the index adjustment slider in the axial direction is from P1 to P2.
And S2, based on the moved adjusting slide block, the compressor piston moves from the top dead center to the bottom dead center to compress the working medium in the cylinder. The working fluid is a refrigerant and refers to a compressed fluid.
As shown in fig. 9, after the linear motor controls the movement of the adjusting slide, the effective volume V of the air cylinder is determined. At the moment, the compressor piston moves from the top dead center to the bottom dead center, and if the working medium entering the cylinder exceeds the current effective volume of the cylinder, the exceeding part of the working medium is discharged from the rear part of the cylinder seat along with the movement of the piston and does not participate in actual compression. If the working medium entering the cylinder does not exceed the current effective volume of the cylinder or the working medium in the effective volume is compressed, the working medium enters the system through the valve bank to complete the refrigeration cycle.
Here, as shown in fig. 10, when the adjusting part front end face of the adjusting slide block is at the position P2, the effective length of the compressor cylinder is the distance L from the piston front end face to the cylinder block front end face min Effective volume of cylinder is V min =A*L min Wherein A is the cylinder cross-sectional area.
When the front end face of the adjusting part of the adjusting slide block is at the position P1, the effective length of the compressor cylinder is the distance L from the front end face of the piston to the front end face of the cylinder cover max Effective volume of cylinder is V max =A*L max Wherein A is the cylinder cross-sectional area.
When the adjusting slide block performs volume adjustment work, the effective length of the compressor cylinder can be L min To L max Can be realized at the maximum effective volume
Figure BDA0003740259790000091
Adjustment to the 100% ratio range; after the volume adjustment is carried out, the effective volume of the cylinder block can be changed to further change the displacement of the compressor under the condition of not changing the high-performance operating frequency of the compressor.
Has the advantages that:
1. the invention is preferably suitable for a reciprocating compressor, the effective volume of the cylinder seat of the compressor can be changed by arranging the adjusting groove which is communicated with the cylinder and extends in the axial direction of the cylinder and the adjusting slide block which can linearly move along the axial direction of the adjusting groove to change the position on the upper part of the cylinder of the compressor, thereby changing the refrigerating capacity of the compressor, further changing the discharge capacity of the compressor under the high-performance operating frequency state of the compressor, achieving the performance under the low refrigerating capacity state of the compressor, effectively realizing the variable proportion adjustment of the effective cylinder volume of the cylinder seat of the reciprocating compressor and changing the discharge capacity of the compressor under the high-performance operating frequency state of the compressor.
