Screw air compressor maintenance once how much money

the maintenance of the screw air compressor is somewhat similar to that of the car. The machine will be maintained for the first time after 500 hours of operation, and then the maintenance is once every 2000 hours.

The first warranty needs to replace the oil (also known as lubricating oil) and the oil filter element. After that, the oil, oil filter element, air filter element and oil and gas separator core need to be replaced for each maintenance.

Consumables selection, the above-mentioned 4 kinds of consumables are generally provided by manufacturers. Good oil products have good oxidation stability, rapid separation, good foam clearing, high viscosity and good anti-corrosion performance. Therefore, users are best to use the maintenance consumables provided by the manufacturers to avoid disputes when the machine fails during the warranty period.

Maintenance method:

1. Start the air compressor to run for 5 minutes, so that the oil temperature rises above 50 ℃, and the viscosity of the oil decreases. 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.

2. Close the oil drain valve when the lubricating oil is 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 range of the oil mark scale line, tighten the screw plug of the oil filler, and check for leakage.

3. Lubricating oil must be checked frequently during use. When the oil level is found to be too low, new oil should be added in time. Condensate water must also be discharged frequently during the use of lubricating oil. Generally, it should be discharged once a week, and it should be discharged once every 2-3 days in high temperature climate. 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.

4. The air filter element can be directly removed and replaced. The oil-gas separator core can be replaced after the oil is released. The first warranty of these two consumables does not need to be replaced.

Note: It is strictly prohibited to mix different brands of lubricating oil for screw air compressor, and avoid overdue use of lubricating oil. Otherwise, the quality of lubricating oil will decrease, the lubricity will be poor, and the flash point will decrease, which will easily cause high temperature shutdown and spontaneous combustion of oil.
