How long does the screw air compressor need to be maintained?

1, small maintenance: only need to replace the air compressor oil and oil filter, usually in the new machine running 500 hours to replace.

2. Major maintenance: In addition to replacing the air compressor oil and oil filter, it is also necessary to replace the air compressor air filter element, oil and gas separator core, motor grease, etc. This maintenance is carried out after the machine runs for about 3000 hours, depending on the work. The environment is very dirty, such as a lot of dust, so this time should be shortened appropriately. Air compressor maintenance is to make the machine better able to run in the best condition.

Just like car maintenance, if it is well maintained, the failure rate of the machine will be greatly reduced, which not only saves the time and effort caused by frequent maintenance, but also prolongs the service life of the air compressor. Therefore, the maintenance of the air compressor must be done well at ordinary times, and do not loathe to give up the maintenance money. Otherwise, when the carbon deposit of the main engine bites this kind of fault, it will cost a lot.

Maintenance and replacement

the quality of screw oil has a decisive influence on the performance of oil injection screw machine. Good oil has good oxidation stability, rapid separation, good foam cleaning, high viscosity and good corrosion resistance. Therefore, users must use pure special screw oil.

The first oil replacement will be carried out after the new machine runs in for 500 hours, and the new oil will be replaced every 2000 hours after operation. It is best to change the oil filter at the same time. Use in harsh environments to shorten the replacement cycle. Replacement method: start the air compressor to run for 5 minutes, so that the oil temperature rose to more than 50 degrees Celsius, oil viscosity decreased.

Stop running. When there is 0.1Mpa pressure in the oil and gas barrel, open the oil drain valve at the bottom of the oil and gas barrel and connect the oil storage tank. The oil drain valve should be opened slowly to prevent the oil with pressure and temperature from splashing and hurting people. Close the oil drain valve after the lubricating oil becomes dripping. Unscrew the oil filter element, drain all the lubricating oil in each pipeline at the same time, and replace it with a new oil filter element.

Open the screw plug of the oil filler, inject new oil to make the oil level within the range of the oil mark scale line, tighten the screw plug of the oil filler, and check for leakage. Lubricating oil must be checked frequently during use. When it is found that the oil level line is too low, new oil should be added in time. Condensate water must also be discharged frequently during use of lubricating oil. Generally, it is discharged once a week, and it should be discharged 2-3 days in high temperature climate. Once.

Shut down for more than 4 hours, open the oil drain valve when there is no pressure in the oil and gas barrel, drain the condensed water, and quickly close the valve when organic oil flows out. It is strictly prohibited to mix different brands of lubricating oil, and avoid overdue use of lubricating oil. Otherwise, the quality of lubricating oil will decline, the lubrication will be poor, and the flash point will be reduced, which will easily cause high temperature shutdown and cause spontaneous combustion of oil.
