The rotor and the stator of the linear motor part do radial linear reciprocating motion to drive the radial piston to move, and different cooling capacities are output by controlling the motion stroke of the piston.

The compressor according to an embodiment of the present invention as shown in fig. 2 further includes: and a pressure detecting device 20 for detecting an acting force generated by the movement of the mover 2 in the cylinder 8.
The mover in the compressor reciprocates in the cylinder, the running stroke is easily influenced by the pressure fluctuation of the suction and exhaust of the system, and when the stroke exceeds a limit value, namely a set position, the runner can impact the exhaust valve plate, the abnormal impact noise occurs, the exhaust valve plate 10 is damaged by impact, the mover falls off and the like. In the above scheme, a pressure detection device is installed in the cylinder to detect the acting force generated by the mover moving in the cylinder, when the mover stroke is within a set range, the pressure detected by the pressure detection device corresponds to a certain value, and when the mover stroke exceeds a set position, the pressure of impact/impact generated by the pressure detection device exceeds a set value, that is, greater than the set value, that is, the mover stroke exceeds a limit value, that is, the set position, can be judged. Therefore, the compressor is subjected to operations such as power reduction, halt and the like according to the judgment result, so that the stroke of the rotor is reduced, damage to devices or the whole machine caused by impact/impact on the exhaust valve plate is prevented, the compressor is protected, the reliability and the safety of the product are improved, and the service life of the compressor is prolonged.
Fig. 3 is a schematic diagram illustrating a structure of a compressor according to an exemplary embodiment. As shown in fig. 3, in the compressor according to the embodiment of the present invention, the pressure detecting device 20 includes: a piezoelectric sensing element 16 installed in the cylinder 8, contacting the mover 2 when the mover 2 moves beyond a set position, and generating a current under an acting force generated by the contact; and a current detection device 19 for detecting the current generated by the piezoelectric sensing element 16.
The compressor of the above exemplary embodiment, further comprising: and a control means 21 for controlling a movement position of the mover 2 based on the current detected by the current detecting means.
In the above scheme, the piezoelectric sensing element 16 senses the impact/impact acting force of the mover, the piezoelectric sensing element converts the acting force into an electrical signal to generate a current, the current detection device detects the current, or compares the detected current with a current set value, and when the detected current exceeds the current set value, it is determined that the movement of the mover exceeds a set position, and an excessive impact/impact may be generated on the exhaust valve plate to damage the exhaust valve plate, that is, the adjustment control of the movement position of the mover is realized by reducing the frequency of the compressor or controlling the compressor to stop and other operations, so that the impact/impact of the mover on the exhaust valve plate is reduced, components and the whole compressor are protected, and the reliability of the compressor product and the stability of the operation are improved.
By way of example, the piezoelectric sensing element 16 is a piezoelectric ceramic material or a piezoelectric crystal material. The piezoelectric ceramics and the piezoelectric crystal are induction devices which can convert force into electricity, and the acting force of the induction rotor is converted into current with corresponding magnitude.
In the above solution, the control device 21 is configured to control the position of the mover 2 to move not to exceed a set position when the current generated by the piezoelectric sensing element 16 is greater than a set current value.
Fig. 3 is a schematic diagram illustrating a structure of a compressor according to an exemplary embodiment. As shown in fig. 3, in the compressor according to the embodiment of the present invention, the piezoelectric sensing element is disposed on the discharge valve plate.

In the compressor according to one embodiment of the present invention as shown in fig. 4, a piezoelectric ceramic structure is disposed on the compressor discharge valve plate 10, another piezoelectric ceramic structure is disposed on the cylinder head 9, a phosphor copper sheet 17 is disposed between the two piezoelectric ceramics, the phosphor copper sheet 17 is used as a positive electrode output, the other ends of the two piezoelectric ceramics are connected together as a negative electrode output, and the positive electrode and the negative electrode are connected to a control device 21 outside the compressor housing through a signal line 18.
When the compressor normally operates and the exhaust valve plate is not impacted, and when the exhaust valve plate is opened for exhaust, the exhaust valve plate is slightly opened for exhaust because the rotor does not impact the exhaust valve plate at the moment. At the moment, the stroke or displacement of the operation of the exhaust valve plate is very small, the two piezoelectric ceramic structures at the rear end of the exhaust valve plate are not extruded by external force, and no electromotive force is generated, or the pressure is very small, and the electromotive force generated by the piezoelectric effect does not reach the threshold value of the electromotive force generated by impact. In this case, it can be considered as normal operation or external interference.
When the compressor mover exceeds a set position, for example 2% or less beyond the edge of the cylinder 8, the frequency of operation of the linear compressor is the natural frequency of the compressor body. The mover is now beyond the edge of the cylinder and hits the exhaust valve 10 at a relatively constant frequency. At this time, the power is high, the impact force is large, and the force applied to the two pieces of piezoelectric ceramics behind the exhaust valve plate 10 is also large, so the electromotive force generated by the piezoelectric effect is large, that is, the amplitude of the impact signal is large, and the frequency is fixed.
After the electromotive force/current signals are monitored, analyzing and processing the signals, and determining that the position of the rotor exceeds a set position under the condition that the electromotive force/current signals meet the condition that the amplitude reaches a set value or meet the condition that the electromotive force/current signals are periodic signals at the same time; the analysis of the emf/current signals in combination with the values and periods of the signals of the exemplary embodiments described above may effectively eliminate false signals generated by normal operation and/or external disturbances.
When the collision signal is monitored, the controller performs operations such as power reduction or shutdown. Damage caused by continuous impact of the mover is prevented. The purpose of protecting the compressor is achieved.

The mover in the compressor reciprocates in the cylinder, and when the stroke exceeds a limit value, namely a set position, the mover can impact the exhaust valve plate, so that the problems of abnormal impact noise, damage to the exhaust valve plate 10, falling off of the mover and the like occur. In the above scheme, the acting force generated by the mover moving in the cylinder is detected, when the mover stroke is within the set range, the detected pressure corresponds to a certain value, and when the mover stroke exceeds the set position, the generated impact/impact acting force/pressure exceeds, i.e. is greater than, the set value, i.e. the mover stroke exceeds the limit value, i.e. the set position, can be judged.
