Common maintenance methods of screw air compressor

If the maintenance of the air compressor is not timely, it will have a great impact on the air compressor. The screw air compressor will have a first guarantee for 500 hours of operation and a maintenance for 2000 hours after operation.

The quality of screw air compressor oil has a decisive influence on the performance of oil injection screw air compressor. Good oil has good oxidation stability, rapid separation, good foam cleaning, high viscosity, good corrosion resistance, therefore, users must use pure special screw oil. It is best to change the oil filter at the same time. Use in harsh environments to shorten the follow-up cycle.

Maintenance method: start the air compressor to run for 5 minutes, so that the oil temperature rose to more than 50 ℃, oil viscosity decreased. When stopping operation, 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 avoid splashing with pressurized and warm lubricating oil.

Close the oil drain valve when the lubricating oil becomes dripping. Unscrew the oil filter element, drain all the lubricating oil in each pipeline at the same time, and replace with a new oil filter. Open the screw plug of the oil filler, inject new oil to make the oil level within the scale of the oil mark, tighten the screw plug of the oil filler, and check whether there is any leakage.

. Lubricating oil must be checked frequently during use, and new oil should be added in time when the oil level is too low. Lubricating oil must also be discharged frequently during use. 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 decrease, the lubrication will be poor, and the flash point will decrease, which will easily cause high temperature shutdown and cause spontaneous combustion of oil.
