[0030] Specifically, the pressure-bearing assembly 100, as the main part that bears the entire pressure-bearing body, has the same shape and size as the compressor, and the pressure-bearing assembly 100 fixes the cylinder 101 through the base 102, which is consistent with the supporting connection method of the compressor. At the same time, in order to save the manufacturing cost of the pressure-bearing assembly 100, the cylinder 101 is made of Q235A, and the pressure-bearing structure is simplified while ensuring the normal operation of the compressor, saving the manufacturing cost.

[0031] Preferably, the inner cylinder assembly 200 simulates the working conditions of the motor stator and rotor inside the compressor, and is consistent with the inner hole size of the stator in the compressor, so that the gap between the stator and the rotor in the inner cylinder assembly 200 is consistent with the gap in the compressor, ensuring that the pressure body simulation process is consistent with the compressor working process.

[0032] Example 2

[0033] Reference Figure 2-4 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that: the cylinder 101 is hollow inside, and connecting flanges 101a are provided at both ends of the cylinder 101, and an annular boss 101b is provided inside the cylinder 101; a stator 101c is provided in the middle of the annular boss 101b, and a mounting groove 101d is provided at one end of the annular boss 101b; baffles 102a are symmetrically provided on the base 102, the cylinder 101 is fixed between the two baffles 102a, and reinforcing ribs 102b are provided on the outer side of the baffle 102a; the end cover 103 is connected to the connecting flange 101a by bolts 103a.

The first sealing sleeve 202b can achieve shaft end sealing, and the second sealing sleeve 202c can achieve exhaust sealing.

[0039] Preferably, the impeller end cover 203 is partially embedded in the mounting groove 101d and fixed to one end surface of the annular boss 101b, while the motor end cover 204 is fixed to the other end surface of the annular boss 101b. The rotor 101 can be completely fixed inside the cylinder 101 through the two end covers.

[0040] Furthermore, the inner cylinder assembly 200 can completely simulate the connection condition of the rotor inside the compressor, and the gap between the rotor 201 and the stator 101c is consistent with the gap between the stator and the rotor of the motor in the compressor.
