The oil pump is responsible for circulating lubricant throughout the compressor, ensuring proper lubrication of internal components and reducing friction. This cover helps protect the oil pump from contaminants and damage, maintaining its efficiency and ensuring the smooth operation of the compressor. It contributes to the overall performance, reliability, and longevity of the compressor in refrigeration and HVAC systems.
