00005. The above maintenance items should be strictly implemented by the user. The maintenance time is different for each brand of air compressor. The most reasonable maintenance time is determined by the user based on the operating status of the air compressor.
00006. 1. What is the maintenance method for the air filter element of the screw air compressor?
00007. The air filter is equipped with a differential pressure switch. When the set value of the differential pressure switch is reached, the differential pressure switch will act, or when the internal fixed time is zero, the LCD shows that the air filter is clogged, indicating that the air filter must be cleaned or replaced. Maintenance should be carried out after the air compressor is shut down and corresponding safety measures have been taken, as follows:
00008. 1. Open the end cover.
00009. 2. Loosen the fixing bolts of the air filter element and take out the filter element.
00010. 3. Check the blockage of the air filter, use compressed air to blow from the inside to the outside to clean up the dust. Note that the pressure of the compressed air does not exceed 0.3MPa.
00011. 4. The air filter element should be replaced when it is damaged. To check whether the air filter element is damaged, you can use an electric lamp to place it in the air filter element and observe whether there is light exposed from the outside.
00012. 5. When the surface of the filter element is stained with oil, replace the air filter element with a new one.
00013. 6. After cleaning or replacing the filter element, cover the end cap.
00014. 7. Check that the differential pressure switch equipped with the air filter is normal, and the preset value does not exceed 50kPa.
00015. .
00016. 2. What is the maintenance method of screw air compressor oil filter?
00017. Whether the oil filter needs to be replaced can be judged by whether the oil filter differential pressure switch is activated or the oil filter timer time is zero. The new machine needs to cause insufficient oil intake after 500h of rotation for the first time, causing high exhaust temperature. Tripping and the lack of oil will affect the life of the bearing. Maintenance should be carried out after the air compressor is shut down and corresponding safety measures have been taken, as follows:
00018. 1. Use belt pliers to unscrew the old filter.
00019. 2. Clean the contact surface.
00020. 3. Apply a thin oil film on the surface of the new filter seal.
00021. 4. Tighten the new filter by hand until the gasket is sealed; in particular, pay attention not to borrow other tools when the new filter is tightened, in case it is difficult to remove it during the next replacement.
00022. 5. Check that the differential pressure switch equipped with the oil filter is installed properly, and the preset value is 150kPa.
00023. 3. What is the maintenance method of the oil and gas separator filter element of the screw air compressor?
00024. Maintenance should be carried out after the air compressor is shut down and the corresponding safety measures have been taken. Small air compressors mostly use rotary oil and gas separator filter elements, and the maintenance method is the same as that of oil filters; the built-in steps are as follows:
00025. 1. Loosen the pipeline on the oil and gas barrel, and at the same time remove the pipeline from the outlet of the pressure maintenance valve (minimum pressure valve) to the aftercooler, remember to ensure that it can be reinstalled correctly.
00026. .2. Loosen and take out the oil return pipe.
00027. 3. Loosen the fastening bolts of the upper cover of the oil and gas barrel, and remove the upper cover of the oil.
00028. 4. Take out the oil and gas separator filter element and replace it with a new oil and gas separator filter element and gasket.
00029. 5. Follow the opposite steps to reassemble and tighten the bolts with a torque wrench.
00030. 6. After the machine is turned on, re-tighten the bolts of the oil and gas barrel cover.
00031. 7. Check that the pressure difference switch equipped with the oil and gas separator filter element on the oil and gas barrel is installed properly. The preset value is 100kPa.
