What are the precautions for installing the piston ring of ammonia refrigeration accessories

Piston ring is a small part of piston compressor in ammonia refrigeration system. It is used as a metal ring for sealing inside the piston. The piston ring includes a gas ring and an oil ring. It may seem small but it plays an important role.

What are the precautions for installing the piston ring of ammonia refrigeration accessories?

　　 Piston ring is a general term, and piston rings installed in different positions are different. The piston ring used in the ammonia refrigeration compressor has the functions of sealing, oil control, heat transfer and guiding. In order to prevent improper operation from affecting the use of the piston ring, what aspects should be paid attention to?

　　 1. The piston ring is installed flat in the cylinder liner, and there must be a certain gap at the interface.

　　 2. The chrome-plated ring should be installed in the first channel, and the opening should not face the direction of the vortex pit on the top of the piston.

　　3. Any piston ring openings should be staggered by 120°C, taking care not to face the piston pin hole.

　　4. When the general torsion ring is installed, the chamfer or notch should be upward; when the conical surface anti-twist ring is installed, keep the cone surface upward.

　　 5. When installing the combination ring, install the axial liner ring first, and then install the flat ring and wave ring. A flat ring is installed on the top and bottom of the wave ring, and the openings of each ring should be staggered.

　　To install the piston ring correctly, please refer to the above refrigeration knowledge for installation. Of course, it is best to be operated by professional refrigeration personnel. Refrigeration is a matter of university. Only through continuous learning and enrichment can we do well in ammonia refrigeration.
