How Bock Hermetic and Open-Type Compressor Parts Work
Bock compressors are one of the most popular applications in marine cooling. They are used in the maritime system to cool down for different applications, such as air-conditioning, food storage, and drink dispensing.

Bock compressors are one of the most popular applications in marine cooling. They are used in the maritime system to cool down for different applications, such as air-conditioning, food storage, and drink dispensing. Consequently, there are two types: hermetic and open type. Each type has various parts and ways of working. In this article, we’ll draw attention to the critical Bock compressor parts and how they function to keep everything cool. Let’s discuss how these parts make it easier to take care of compressors and keep them running for a long time.
Hermetic Compressors
Bock semi-hermetic compressors seal all the essential parts inside one unit. This stops air or water from sneaking in and causing problems. The parts of a Bock semi-hermetic compressor include:
• Piston and Cylinder: The piston twists up and down movement within the cylinder, compressing the gas tightly. This repeated motion pushes gas through the system, preparing it for cooling.
• Crankshaft: The main mechanism of crankshaft is to spin the piston, which connects to the motor, transforming energy into mechanical power for compression.
• Motor: The motor powers the whole thing and helps the crankshaft move. It provides the necessary force to keep the entire system running smoothly.
• Valves: Suction valves pull in the gas. Discharge valves push the compressed gas out. These valves control the flow of gas with perfect timing.
• Gaskets: These prevent leaks, keeping the compressor airtight. They shield the internal Daikin compressor parts, ensuring efficient performance without loss.
Gas enters through the suction valves. The crankshaft spins, pushing the piston to compress the gas. Compressed gas then exits through discharge valves.
Open Type Compressors
Bock open-type compressors look different because the motor sits separately. This design makes it easy to fix or change parts. Essential parts of Bock open-type compressors include:
• Shaft Seal: This stops refrigerant from slipping out.
• Coupling: It links the motor and compressor, sharing power between them.
• Oil Pump: It splashes oil on moving parts to keep them smooth.
• Suction and Discharge Valves: These move gas in and out, like in hermetic compressors.
Gas enters the cylinder through the suction valve in a bock open compressor. The motor rotates the crankshaft, compressing the gas tightly. Compressed gas escapes through the discharge valve.
Why Compressor Parts Matter
Each part of a compressor works together to cool in commercial refrigeration systems. The crankshaft and piston squeeze gas. Valves let gas in and push it out. Seals stop leaks, while the oil pump keeps things running smoothly. These parts must work well together for the compressor to do its job.
Choosing the Right Parts
When picking parts for your Bock compressor, it is highly recommended to opt for original parts. These components help the compressor run longer and work better. A trusted Bock compressor parts supplier, like Fair Sky (China) Co. LTD, gives you the right parts to keep everything cool.
The End Note
Bock hermetic and bock open-type compressors need different parts to work well. Every part does an important job, like squeezing gas or stopping leaks. Taking care of these parts helps compressors last a long time. Getting the right parts from a trusted Bock compressor supplier keeps things running smoothly. When your compressor has the right parts, it stays strong and works for years.
