Air compressor daily maintenance matters needing attention

Air compressor maintenance and maintenance

daily maintenance: good maintenance and maintenance is the guarantee of the normal operation of the unit, but also to reduce the wear of parts and extend the life of the compressor unit. Before starting the machine, check the compressor lubricating oil level. If the oil level is too low, add oil to check whether the joints are reliable and whether there are bolts and nuts loose or damaged. After the unit is started, check whether each value displayed on the display is normal, check whether the unit has leakage phenomenon, if any, immediately shut down and release all pressure of Part C for treatment.

Lubricating oil use and maintenance time; Lubricating oil has a decisive influence on the performance of screw air compressor. Improper use or error will cause serious damage to the compressor body and may even cause a fire. Therefore, special oil for air compressor must be used.

Air compressor oil change steps

(1) Run the air compressor to increase the oil temperature to facilitate discharge, and then press the switch button to stop running.

(2) Open the drain valve to drain the lubricating oil in the oil and gas barrel.

(3) After the lubricating oil is discharged, close the oil drain, open the lid and inject new oil, and pay attention to draining all the lubricating oil in the system, such as pipes, coolers, oil and gas barrels, etc.

(4) Tighten the fuel filler cap, and then shut down after starting up and running for about 5-10 minutes. Observe that the oil level should be between the upper and lower limits.

Air compressor lubricating oil use matters needing attention

when the air compressor is used for the first time, the first oil change should be replaced after 500 hours of use. Under normal circumstances, the oil should be replaced once in 3000 hours. Remember that the lubricating oil exceeds the service life of the oil, and the lubricating oil should be replaced on time. Otherwise, the quality of the lubricating oil will decrease, and the lubrication effect will easily cause high temperature tripping and carbon deposition. At the same time, because the ignition point of the lubricating oil decreases, it is also easy to form the spontaneous combustion of the lubricating oil. The air compressor burned down.

Air compressor three filter one oil, refers to the air compressor air filter, oil filter, oil and gas separator and screw air compressor oil four kinds of consumables, air compressor regular maintenance work is to replace these accessories. The following is a summary of the daily maintenance and maintenance methods of air compressor.

1. screw air compressor oil filter replacement.

The first running period of the new machine is generally 500 hours, and the oil filter needs to be replaced.

It is recommended to replace the new oil filter every 2000 hours or so. It is best to replace the oil filter at the same time when changing the oil. The replacement cycle should be shortened when the environment is bad. The service life of oil filter and screw air compressor oil has a great relationship with the cleanliness of air filter.

It is strictly prohibited to use the oil filter element beyond the time limit. Otherwise, due to the serious blockage of the filter element and the pressure difference exceeding the bearing limit of the bypass valve, the bypass valve will automatically open, and a large amount of stolen goods and particles will directly enter the main engine of the screw air compressor, causing serious consequences.

Maintenance and maintenance of air filter element of 2. screw air compressor.

The air filter element is the goalkeeper that filters out air impurities, and the filtered clean air enters the compression chamber of the screw rotor for compression. Air filter should be maintained once a week, with compressed gas, from the inner cavity outward blowing dust particles on the outer surface of the air filter.

The air filter element is replaced every 1000-2000 hours under normal conditions. For places where the environment is particularly harsh, such as mining, paper industry, and textile industry, it is recommended to replace the air filter element every 1000 hours.

Maintenance and replacement of oil and gas separator of 3. screw air compressor.

The function of the oil and gas separator is to separate the oil and gas mixture. Under normal use, the life of the oil separator is about 3000 hours, but the quality of the lubricating oil and the filtration accuracy of the air have an important impact on its life. In harsh environments, the maintenance and replacement cycle of the air filter element must be shortened.

The oil and gas separator must be replaced after about 3000 hours of use or after the pressure difference exceeds 0.12Mpa. Otherwise, it will cause the motor overload, excessive current, electricity consumption, and the oil separator is easy to be damaged and run oil.

Maintenance and replacement of 4. screw air compressor oil.

The quality of screw air compressor oil has a decisive influence on the stability of oil injection screw air compressor. Good oil has good oxidation stability, rapid separation, good foam cleaning, high viscosity and good corrosion resistance. Therefore, users must use special screw oil matched with equipment.

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. It is best to change the oil filter at the same time. Use in harsh environments to shorten the replacement cycle.

If the air compressor oil is replaced in the cold state, the air compressor should be started to run for 5 minutes to reduce the viscosity of the oil. Stop the operation completely, 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 the body with pressurized and warm lubricating oil.

The use of the process must be frequent inspection, found that the oil level line is too low should be timely to add new oil, lubricating oil use must also be often discharged condensate, the general situation once a week, in high temperature climate should be 2-3 days of discharge.

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.
