Methanol Weekly Topic: What are the components of a compressor’s lubrication system? 2016.04.17---2016.04.25 What are the components of a compressor’s lubrication system? How does it work? Answer: It mainly consists of a fuel tank, fuel pump, oil cooler, oil filter, pressure accumulator, surge tank, as well as instruments and piping accessories. In addition to storing oil, the tank also serves to separate water, sediment, and bubbles from the oil. What is the function of a pressure regulator? The function of the accumulator is to prevent the unit from stopping automatically due to low oil pressure, during the startup of the backup pump when the normally operating oil pump fails. The function of the lubricating oil sump is to ensure that, in the event that a normally operating oil pump fails and the backup pump cannot be started for some reason, the automatic shutdown of the unit due to a lack of lubricating oil can be avoided; the sump then provides oil to allow the bearings to cool down gradually. The oil pump provides sufficient pressure for the lubricating oil. The oil cooler is used to cool the lubricating oil, maintaining its temperature at an appropriate level. This prevents the bearing shells from overheating due to high oil temperatures, as well as reduces the risk of deterioration in the quality and lifespan of the lubricating oil, or even carbon formation.

The lubrication system of a general compressor consists of components such as a lubricating oil tank, main oil pump, auxiliary oil pump, oil cooler, oil filter, high-level oil tank, valves, and pipelines. The lubricant tank is a device for the supply, recovery, sedimentation, and storage of lubricant; it is equipped with a heater inside to warm the lubricant before operation. Lubrication pumps are generally equipped in pairs: a main oil pump and an auxiliary oil pump. The lubricating oil required for the operation of the unit is supplied by the main oil pump ； The auxiliary oil pump is activated automatically to come online when the main oil pump fails or there is a fault in the oil system, resulting in a drop in system oil pressure. The lubricating oil cooler is used to cool the lubricating oil of the oil pump, in order to control the temperature of the oil that enters the bearings. Lubricant filters are used to filter the lubricant entering the compressor, in order to ensure its quality. The high-temperature oil tank serves as a backup; when the main and auxiliary oil pumps fail and the supply of lubricating oil is interrupted, the lubricating oil in the high-level oil tank flows to various lubrication points through the oil inlet pipes, driven by gravity, in order to maintain the operation of the machine.

The lubrication system of a general compressor consists of components such as a lubricating oil tank, main oil pump, auxiliary oil pump, oil cooler, oil filter, high-level oil tank, valves, and pipelines. I. Lubricating Oil Tank: The lubricating oil tank is a device for the supply, recovery, sedimentation, and storage of lubricating oil. It is equipped with a heater that is used to warm the lubricating oil before the machine starts up, ensuring that its temperature reaches the range of 35–45°C at the time of startup, thereby meeting the requirements for the proper operation of the machine ； The oil return port and the pump’s suction inlet are located on opposite sides of the oil tank, with a filtering baffle in between; this allows the lubricating oil returning to the tank time to have impurities settle and gases to be released, thereby ensuring the quality of the lubricating oil. The side walls of the fuel tank are equipped with level indicators to monitor changes in the lubricating oil level within the tank, thereby preventing sudden fluctuations in this level during operation of the unit and avoiding any impact on its safe operation. II. Lubricating Oil Pumps: Generally, two lubricating oil pumps are installed – one main oil pump and one auxiliary oil pump. The lubricating oil required for the operation of the unit is supplied by the main oil pump ； The auxiliary oil pump is activated automatically in case of a failure in the main oil pump or an issue with the oil system, which leads to a drop in system oil pressure; it supplies an appropriate amount of lubricating oil to all the lubrication points of the unit. The flow rate of this oil pump is generally between 200 and 350 L/min, and the outlet pressure should be no less than 0.5 MPa. The lubricating oil is reduced in pressure before reaching the bearings, at a pressure of 0.08 to 0.15 MPa. III. Lubricating Oil Cooler The lubricating oil cooler is used to cool the lubricating oil after it passes through the oil pump, in order to control the temperature of the oil that enters the bearings. To maintain the oil supply temperature within the range of 35–45°C, two oil coolers are generally installed: one is in use while the other serves as a backup (in special cases, both can be used simultaneously). When the cooling performance of the cooler in use fails to meet the production requirements, it is switched to the backup cooler to maintain production, while the decommissioned cooler is taken apart for inspection; after removing the dirt, it is reassembled and put back into use. IV. Lubricating oil filter: The lubricating oil filter is installed at the outlet of the pump and is used to filter the lubricating oil that enters the compressor; it is an effective measure to ensure the quality of the lubricating oil. To ensure the safe operation of the unit, two filters are installed for each one, with one in operation and one as a backup. V. High-level oil tank: The high-level oil tank is a protective device; when the supply of lubricating oil from the main and auxiliary oil pumps is interrupted, the lubricating oil in the high-level oil tank flows to various lubrication points through the inlet pipes, driven by gravity, to meet the lubrication requirements during the idle operation of the unit. The fuel storage capacity of the high-position tank should generally be sufficient to ensure a fuel supply duration of no less than 5 minutes.
