What are the effects of oil temperature, oil pressure, and oil level on a refrigeration unit?

The lubricating oil system is an indispensable part of the normal operation of all refrigeration units, which provides lubrication and cooling conditions for the moving parts of the refrigeration units. Screw chillers and some piston chillers also need to utilize lubricating oil to control energy regulation devices or pumping recovery devices.
At present, piston chillers store the lubricating oil in the crankcase of the compressor, while screw chillers have an independent lubricating oil system with its own oil reservoir and an oil cooler specially designed to reduce the oil temperature. Therefore, the oil temperature, oil pressure difference and oil level height of the appropriate or not will have an important impact on the chiller, refrigeration encyclopedia here to do a simple comb, I hope to help you.
First, the oil temperature
Oil temperature, refers to the temperature of the lubricating oil when the chiller is working. The oil temperature will have an important impact on the viscosity of the lubricant. Oil temperature is too low, then the viscosity of the oil increases, the fluidity decreases, it is not easy to form a uniform oil film, so it can not achieve the expected lubrication effect, but also cause the oil flow rate decreases, so that the lubrication volume decreases, the power consumption of the oil pump increases; the oil temperature is too high, the viscosity of the oil will decrease, the oil film does not reach a certain thickness, so that the operating parts are difficult to withstand the necessary pressure, resulting in lubrication deterioration, so that the movement of parts Increased wear and tear, resulting in chiller failure.
Second, the oil pressure difference
It is the lubricating oil in the oil pump drive, in the oil system pipeline flow to the working parts of the flow resistance to overcome the security. Without enough oil pressure difference, can not ensure that the lubrication system of the chiller has enough lubrication and cooling oil and drive the power needed to regulate the energy device, therefore, the oil pressure difference of the chiller oil system must be ensured in a reasonable range, so as to facilitate the unit moving parts to be fully lubricated and cooled, and flexible manipulation of energy regulation device.
Third, the oil level height
It refers to the height of the liquid level of the lubricating oil in the oil storage container. Chiller oil storage containers are set up with oil level display device, the general provisions of the oil storage containers in the oil level height should be located in the central level of the sight glass under 5 mm. the purpose of the oil level height is to ensure that the oil pump in the work, the formation of the oil cycle required by the oil volume is sufficient. The oil level is too low to cause the oil pump is insufficient, thus causing operational failure or damage to the equipment.
