What is the effect of oil temperature on the refrigeration unit?
The lubricating oil system is an integral part of the normal operation of all refrigeration units, providing lubrication and cooling conditions for the moving parts of the refrigeration unit. Screw chillers and some piston chillers also require the use of lubricating oil to control the energy conditioning device or the suction recovery device.
At present, the piston chiller stores the lubricating oil in the crankcase of the compressor. The screw chiller has a separate lubricating oil system, has its own oil storage, and an oil cooler specially designed to reduce the oil temperature. Therefore, the appropriateness of oil temperature, oil pressure difference and oil level will have an important impact on the chiller. The refrigeration encyclopedia is here to do a simple combing, I hope to help everyone.
Oil temperature refers to the temperature of the lubricating oil when the chiller is working. The temperature of the oil will have an important effect on the viscosity of the lubricant. If the oil temperature is too low, the viscosity of the oil increases, the fluidity decreases, and a uniform oil film is not easily formed, so that the desired lubrication effect cannot be achieved, and the flow speed of the oil is lowered, the lubrication amount is reduced, and the power consumption of the oil pump is reduced. Increase; oil temperature is too high, the viscosity of the oil will drop, the oil film will not reach a certain thickness, so that the running parts are difficult to withstand the necessary working pressure, resulting in deterioration of the lubrication condition, causing the wear of the moving parts to intensify, causing the chiller to malfunction.
