structure
The cylinder body is usually made of high-strength materials such as cast iron, aluminum alloy, etc., to ensure sufficient strength and durability in high-pressure and high-temperature environments.
The interior of the cylinder is smooth to reduce friction and wear during piston movement.
There are intake and exhaust ports on the cylinder block for the suction and discharge of refrigerant.
Function:
The cylinder provides space for the piston and piston rod to move back and forth, thereby compressing the refrigerant.
The cylinder body is closely matched with the piston, piston rod and other components to form a sealed working chamber, ensuring that the refrigerant will not leak during the compression process.
The cylinder body also bears the pressure and temperature changes generated during the compression process, so it needs to have sufficient strength and heat resistance.
