Circulating compressors are used in refrigeration systems to compress refrigerant vapor and pump it through the system. They come in different sizes and configurations, depending on the application and the amount of refrigerant that needs to be compressed. In this article, we will discuss the components and functions of circulating compressors.
Cylinders
Circulating compressors can have one or more cylinders, depending on the size and capacity of the compressor. Each cylinder houses a piston that compresses the refrigerant vapor. The number of cylinders affects the compressor's efficiency and power. For instance, compressors with more cylinders can handle more refrigerant and provide more cooling power.
Crankshaft
The crankshaft is a rotating shaft that connects the pistons to the electric motor. As the motor rotates, the crankshaft converts the linear motion of the pistons into rotational motion. The size and strength of the crankshaft depend on the compressor's size and capacity.
Valves
Valves regulate the flow of refrigerant vapor into and out of the cylinders. There are two types of valves in a circulating compressor: suction valves and discharge valves. Suction valves open to allow refrigerant vapor to enter the cylinder, while discharge valves open to allow compressed refrigerant vapor to exit the cylinder.
Oil Pump
The oil pump is responsible for lubricating the compressor's moving parts, such as the pistons, crankshaft, and bearings. The oil pump ensures that the compressor runs smoothly and efficiently. Without adequate lubrication, the compressor's moving parts can wear out quickly and cause the compressor to fail.
Conclusion
Circulating compressors are crucial components in refrigeration systems. Understanding their components and functions is essential in ensuring that these systems operate smoothly and efficiently. By knowing the number of cylinders, the crankshaft, valves, and oil pump, you can diagnose and troubleshoot problems that may arise during operation.
