In addition, certain equipment, such as certain types of compressors, has integrated systems for cooling and lubricating, so that there is only a working fluid circuit with a single covering, simultaneously, the lubrication and cooling needs..The cooling and lubrication are, together with the operation and regulation, the most important systems that integrates a instrument and allow them to work under standard conditions of service. Moreover, the random mix of coolant and oil can be harmful, especially in air and moisture.Although not always indispensable, sometimes have to be made by cooling lubricant, especially in huge machinery (high power generators) and oleohydraulic transmissions through a warm exchanger which circulates a precise quantity of water or cooling of the mechanism itself.
This notion is applicable to a Variety of equipment for the machining of metals, engines, etc.To finish, it should be highlighted that both the lubrication and cooling, as well as enabling the operation of machinery and lengthen its useful life, are part of routine maintenance operations.In the design project of a device, besides the fatigue calculation of items such as trees, gears or bearings, it is indispensable to delimit also the cooling and lubrication systems, specifying the procedure to be used in each instance, the components and the type of fluid refrigerant and / or lubricant. The fortuitous inclusion of a certain amount of refrigerant into the lubrication circuit and the consequent reduce of the viscosity and lubricity of the oil, can initiate the decomposition and accelerate oxidization of metal surfaces of the circuit.. Similarly, the presence of grease in the cooling system reduces efficiency and requires disposal of oil available independently.
This question, as its known, is particularly critical in refrigeration equipment. Excluding exceptional cases, as we shall see, in the vast majority of manufacturing machinery and equipment, cooling systems and lubrication are unconnected. Launching of the mechanical elements is essential to lubricate the contact surfaces, while maintaining operating temperatures within Correct Limits. As a common rule, you should use coolants and lubricants of extreme quality, prevent the presence of contaminants dryer heat transfer Suppliers and provide locking mechanisms and appropriate insulation to prevent the interference of the two systems.
