Further, the rotating part 32 also includes magnetic sheet 324, the mutually distant side wall of the rotor 322 is fixedly connected with a plurality of groups of magnetic sheet 324, the inner wall of the shell 311 on both sides of the rotor 322 is fixedly connected with a group of stator 325 through the fixed block, the end of the stator 325 away from the second rotating shaft 321 is fixedly connected with winding 326 corresponding to the magnetic sheet 324; Cooling groove 314 is arranged near the position of the weight ring 323; In use, the winding 326 is started, the winding 326 drives the rotor 322 to rotate through the magnetic sheet 324, the rotor 322 drives the second rotating shaft 321 and the weight ring 323 to rotate, the second rotating shaft 321 drives the first rotating shaft 212 to rotate, the first rotating shaft 212 drives the eccentric rotating rod 221 to rotate around the axis of the first rotating shaft 212, at this time the eccentric rotating rod 221 drives the bearing 222 to move away from or close to the compression cylinder body 213, at this time the bearing 222 drives the driving slider 224 to move through the connecting rod 223, the driving slider 224 drives the piston 226 to reciprocate in the inside of the compression cylinder body 213 under the limitation of the cross slide 225, because the piston 226 is attached to the inner wall of the compression cylinder body 213, so that the piston 226 compresses the fluid in the compression cylinder body 213, thereby realizing the compression processing of the fluid;

Since the second rotating shaft 321 is directly fixedly connected with the first rotating shaft 212 as a whole, the second rotating shaft 321 and the first rotating shaft 212 do not need to be connected by a shaft coupling, thereby reducing the use of bearings and the energy loss, and improving the working efficiency of the device; Since the weight ring 323 is fixedly connected to the outer end of the rotor 322, the overall weight of the rotor 322 is increased, thereby increasing the moment of inertia of the rotor 322 when rotating, so that the energy storage flywheel does not need to be added to the first rotating shaft 212, thereby ensuring the stable operation of the device, especially when the device is started and stopped, the energy storage flywheel is prevented from aggravating the vibration of the device, and the service life of the device is improved. Since the weight ring 323 is added to the outer end of the rotor 322 to replace the energy storage flywheel, the installation space of the device is not changed, and since the weight ring 323 is installed to the outer end of the rotor 322, the rotating radius of the weight ring 323 is large, so that the weight ring 323 can achieve a large moment of inertia with a small weight, thereby achieving the effect of reducing the installation space of the device. Since the shaft coupling and the energy storage flywheel are reduced, the overall structure of the device is simplified, the functions are integrated, and the maintenance and operation costs are saved.

[0031] Embodiment 2, refer to Figure 6 and Figure 7 The second embodiment of the present application is different from the previous embodiment in that it includes two groups of motor assemblies 3, The two ends of the main body 211 are fixedly connected with a group of housings 311, and the two ends of the first rotating shaft 212 are fixedly connected with a group of second rotating shafts 321, and the mutually remote ends of the second rotating shafts 321 are rotatably connected to the inner walls of the housings 311; The outer walls of the second rotating shafts 321 are fixedly connected with a group of rotors 322, the side walls of the rotors 322 away from the second rotating shafts 321 are fixedly connected with weight rings 323, the mutually remote side walls of the rotors 322 are fixedly connected with a plurality of groups of magnetic sheets 324 at equal intervals, and the inner walls of the housings 311 on the mutually remote sides of the rotors 322 are fixedly connected with a group of stators 325, and the outer ends of the stators 325 are fixedly connected with windings 326 corresponding to the magnetic sheets 324 at equal intervals; In use, the windings 326 on both sides of the housings 311 are started at the same frequency, the windings 326 drive the two groups of rotors 322 to rotate synchronously through the magnetic sheets 324, the two groups of rotors 322 drive the second rotating shafts 321 to rotate, the second rotating shafts 321 drive the first rotating shaft 212 to rotate, and the first rotating shaft 212 drives the bearing 222 to rotate around the first rotating shaft 212 through the eccentric rotating rod 221, the bearing 222 drives the driving sliding block 224 to reciprocate in the limiting of the cross sliding sleeve 225, and the piston 226 reciprocates in the compression cylinder 213 and compresses the fluid in the compression cylinder 213. By setting two groups of rotors 322 and weight rings 323, the rotational inertia of the two ends of the first rotating shaft 212 is increased, so that the axial force of the device during operation is fully offset, further increasing the service life of the device; And because a driving source is added to both ends of the first rotating shaft 212, the power of the driving source can be appropriately reduced, avoiding the problem of easy damage under high-power operation of the driving source. Compared with a single driving source, the use of a double driving source reduces the volume of the driving source and increases the power coverage, thereby making the device structure more reasonable; Because the outer ends of the two groups of rotors 322 are fixedly connected with the weight rings 323, the overall heat dissipation area of the rotors 322 is further increased, thereby further improving the heat dissipation efficiency of the rotors 322.
