What is the cause of insufficient displacement of Copeland compressor

Insufficient compressor displacement has a great impact on the entire refrigeration system. If it is not repaired and handled in time, it may cause problems such as the cylinder, cylinder head rupture, and compressor water intake, which will destroy the entire refrigeration system cycle. It may even cause accidents such as compressor combustion and explosion. So what causes the insufficient displacement of Copeland compressor? Let's take a look.
