Matters needing attention in the application of Copeland compressors

Matters needing attention in the application of Copeland compressors Most cold storage construction merchants or unit assembly companies have dealt with Copeland compressors. Although Copeland compressor design and production personnel have designed enough pre-class work for the situations that may be encountered during use, but Well, the so-called wise man will lose a lot. For some things, we still have to ask the teachers for advice. Below we share the things that Copeland compressors need to pay attention to in the application. 1. Pressure and temperature setting of Copeland compressor 1. It is very important to monitor the pressure and temperature in the compressor scroll application. In the 2-6P scroll compressor, it is necessary to set the exhaust line thermostat. The purpose is to switch off the refrigeration compressor at 125°C or below. 2. The thermostat must have good thermal insulation performance, and the distance from the discharge connection to the compressor must be maintained at 5 inches. In addition, it is necessary to control the high pressure and low pressure of the compressor. The low pressure is mainly used to prevent the damage of the compressor caused by high vacuum. 2. Can Copeland compressors operate on liquids? 1. The answer is yes, and because of the axial and radial flexibility of Copeland Scroll compressors, it can handle liquids better than most compressors. But it must be equipped with necessary accessories; 2. The accessories for the Copeland compressor to operate the liquid are: for systems with large refrigerant capacity or uncontrollable refrigerant backflow, the storage and crankcase heater must be configured; 3. How to achieve oil management in Copeland compressors? 1. Refrigeration compressors must have an oil management system to maintain the correct oil level in the crankcase. 2. The oil pump of the scroll compressor does not have oil pressure safety control, so the scroll compressor must be equipped with an external oil level controller; this external oil level controller must ensure that the oil level cannot return to the normal level and cut off the refrigeration. compressor.
