Turbine oil pollution control includes control during the blending and production of turbine oil as well as control during operation. In the production process of turbine oil, filtration is used primarily to remove solid impurities. When controlling the contamination level of turbine oil during operation, in addition to solid particles, moisture must also be removed. The required contamination levels for turbine oil are listed in the table below. Gear oil filters are primarily used for the highly precise filtration of solid impurities from various types of gear oil, lubricating oil, insulating oil, etc., especially for filtering oils with high viscosity that cannot be filtered by ordinary filters. It is the next-generation version of the plate and frame pressure filter. For applications where only mechanical impurities need to be removed, this machine is more flexible, convenient, cost-effective, and precise than vacuum oil filters. It has a wider range of applications and a longer lifespan than ordinary pressure filters; it can be used for heating at a constant temperature to reduce viscosity, does not require filter paper replacement, and offers high and stable filtration precision. Therefore, gear oil filters are widely used in industries such as power generation, manufacturing, automotive, railways, metallurgy, steel rolling, aviation, and mining. They are used for deep filtration of gear oil, hydraulic oil, turbine oil, machine oil, compressor oil, spindle oil, insulating oil, and all other liquid oils with lubricating properties; however, they cannot be used to filter liquids that lack lubricating effects or are flammable, such as ethanol and gasoline. When the oil filter is in operation, the contaminated oil is drawn in through the inlet under the effect of external atmospheric pressure and vacuum; it then enters the heater. After being heated, the oil passes through the primary filter, where larger particles of impurities are removed. Subsequently, the oil goes on to the water separator and vacuum separator, flowing through a specially designed diverging device. This diverging device creates a large surface area per unit volume of oil, exposing the contaminated oil to an atmosphere with a very low relative humidity, thereby removing water, air, and gases from the oil. The mixed gas formed by the evaporated water vapor and gases is condensed into a liquid through the water tank and cooler, and then enters the water storage tank together; the remaining gas is removed by vacuum. The water-free oil is pumped by an oil discharge pump into a fine filter to remove particulate impurities, resulting in purified oil and thus completing the purification process. Depending on the level of water content, multiple cycles are required to completely remove all water. 1. All components of the oil filter have been tested and adjusted before leaving the factory; upon arrival at the installation site, it is necessary to check whether each part is intact. 2. The oil filter should be placed firmly; the oil inlet should be connected to the drain port at the bottom of the fuel tank, while the oil outlet should be connected to the upper part of the fuel tank. 3. Connect the oil filter to the power supply and ground wire. The distribution panels on the aircraft, as well as the connection points of the oil pumps, vacuum pumps, and heaters, should all be inspected to ensure that the connections are secure and the insulation is reliable. 4. Attempt to start the oil pump motor and observe whether it rotates in a clockwise direction (when viewed from the front of the motor). Otherwise, swap the phases of the power supply. 5. When treating hydraulic oil and other machine oils online, it is necessary to replenish oil of the same grade appropriately to maintain a proper oil level in the tank.
