What is the maintenance method of screw air compressor oil and gas separator filter element? Maintenance should be carried out after the air compressor is stopped and the corresponding safety measures are made. Small air compressors mostly use rotary oil and gas separator filter elements, and their maintenance methods are the same as oil filters; The built-in step is as follows: loosen the line on the oil and gas barrel and remove the line from the outlet of the pressure retention valve (minimum pressure valve) to the aftercooler, remembering to ensure correct reloading. Loosen and remove the return line. Loosen the fastening bolts on the lid of the oil and gas barrel and remove the lid. Take out the oil and gas separator filter element and replace it with a new oil and gas separator filter element and gasket. Reload in the opposite step, using a torque wrench to tighten the bolts.

　　After the machine is turned on, re-tighten the oil and gas barrel cover bolts. Check that the differential pressure switch equipped with the oil and gas separator filter element on the oil and gas barrel is installed normally, and the preset value is 100kPa. The oil-gas separator is a component that separates the screw lubricating oil from the compressed air, under normal operation, the service life of the oil-gas separator is about 3000 hours, but the quality of the lubricating oil and the filtration accuracy of the air have a huge impact on its life. It can be seen that in the harsh use environment, the maintenance and replacement cycle of the air filter element must be shortened, and even consider installing a front air filter. The oil and gas separator must be replaced after expiration or the pressure difference between the front and rear exceeds 0.12Mpa. Otherwise, it will cause the motor to be overloaded, and the oil and gas separator will be damaged and run oil.
　　
　　Replacement method: remove each control pipe joint installed on the oil and gas drum cover. Take out the oil return pipe on the lid of the oil and gas barrel that extends into the oil and gas drum, and remove the fastening bolt of the upper lid of the oil and gas drum. Remove the lid of the oil and gas drum and remove the oil fine separator. Remove asbestos pads and dirt stuck to the upper cover. Load a new oil fine separator, pay attention to the upper and lower asbestos pads must be nailed and stapled, and the asbestos pads must be neatly arranged when pressing, otherwise it will cause punching pads. Install the upper cover plate, oil return pipe, and control pipe as they are, and check whether there is any leakage.
　　
　　What is the maintenance and replacement method of screw oil? The quality of screw oil has a decisive impact on the performance of the oil-injected screw machine, good oil has good oxidation resistance, fast separation, good foaming, high viscosity, good anti-corrosion performance, therefore, users must use pure screw oil of the company. The first oil is changed after the running-in period of 500 hours of the new machine, and the new oil is replaced every 2000 hours of operation. It is best to replace the oil filter at the same time when changing the oil. Use in harsh environments to shorten replacement cycles. Replacement method: start the air compressor to run for 5 minutes, so that the oil temperature rises above 50 °C, and the viscosity of the oil decreases. Stop running, when there is 0.1Mpa pressure in the oil and gas drum, open the drain valve at the bottom of the oil and gas drum and connect the oil storage tank. The oil drain valve should be opened slowly to avoid splashing and injuring people with pressure and warm lubricating oil. After waiting for the lubricating oil to become droplets, close the oil drain valve. Unscrew the oil filter element, drain the lubricating oil in each pipeline at the same time, and replace it with a new oil filter element. Open the oil filler screw plug, inject new oil, make the oil level within the oil scale line, tighten the oil filler screw plug, and check whether there is leakage.
　　
　　Lubricating oil must be checked frequently during use, and new oil should be replenished in time when the oil level line is too low, and condensate must also be frequently discharged in the use of lubricating oil, generally discharged once a week, and should be discharged once in 2-3 days in a high temperature climate. Stop for more than 4 hours, open the oil drain valve without pressure in the oil and gas drum, discharge condensate, and quickly close the valve when you see the organic oil flowing out. Lubricating oil is strictly forbidden to mix different brands, avoid the use of lubricating oil beyond the deadline, otherwise the quality of lubricating oil will decrease, the lubricity will be poor, and the flash point will be reduced, which will easily cause high temperature shutdown and cause spontaneous combustion of oil.
　　
　　> screw air compressorWhat is the maintenance method of the cooler? The heat dissipation effect of the cooler directly affects the use temperature of the air compressor. The plate-fin structure is easy to collect dust, so the cooler maintenance needs to be blown from top to bottom with dry compressed air of more than 0.4Mpa per shift. The cooler of the diesel-driven screw is upright, and it is necessary to use dry compressed air above 0.4Mpa to blow from the outside to the inside during maintenance, and then clean up the dust and particles in the wind shroud after blowing to prevent the fan from being blown into the cooler again and causing blockage, causing high temperature of the machine. If the machine is used in a harsh environment and the surface of the cooler is full of oil, it must be cleaned with a carbon-forming cleaning agent.
