[0002] The main function of a compressor is to raise low-pressure gas to high-pressure gas by its internal mechanical structure (such as a screw rod, etc.) to compress the gas and increase the pressure of the gas. This pressure increase is necessary in many industrial processes, such as gas transportation and separation in petroleum and chemical production, and condensation and evaporation processes in refrigeration systems.

[0003] The suction end seat and the exhaust end seat are important components of a compressor and play a key role in the gas circulation process of the compressor. The suction end seat not only provides an air inlet channel for the compressor, but also ensures that the gas can enter the interior of the compressor smoothly and efficiently through its internal structure, providing necessary conditions for the gas introduction process; the exhaust end seat is responsible for discharging the compressed gas, and the two work together to ensure that the compressor can continuously and stably compress and discharge the gas.

[0004] When assembling the compressor, the compressor with the suction end seat is placed horizontally, and the next step is to assemble the exhaust end seat. The exhaust end seat involves components such as a screw rod, which is heavy and generally needs to be hoisted for assistance. If it is assembled horizontally, hoisting will not work, and manual assembly not only has high labor intensity, but also has safety hazards, so a compressor turnover device with simple structure is needed, which can turn the compressor 90 degrees to meet the assembly requirements of components such as screw rods.
