Maintenance of air compressor

In order to make the air compressor run normally and reliably, and ensure the service life of the unit, it is necessary to make a detailed maintenance plan, implement special operation, regular maintenance and regular inspection and maintenance, and keep the air compressor unit clean, oil-free and dirt-free.

note:

A. When repairing and replacing various components, it must be confirmed that the pressure in the air compressor system has been released and isolated from other pressure sources, and the switch on the main circuit has been turned off, and a safety sign that it is not allowed to turn off is made.

B The replacement time of compressor cooling lubricating oil depends on the use environment, humidity, dust and whether there is acid-base gas in the air. The newly purchased air compressor must be replaced with new oil after the first operation of 500 hours, and then every 4000 hours according to the normal oil change cycle, and the machine with an annual operation of less than 4000 hours should be replaced once a year.

C. The oil filter must be replaced after 300-500 hours for the first use, and every 2000 hours according to the normal time after 2000 hours for the second use.

D when repairing and replacing the air filter or air inlet valve, remember not to let any sundries fall into the main cavity of the compressor. When operating, close the host entrance. After the operation, turn it by hand several times according to the rotation direction of the main engine, and then turn it on after confirming that there are no obstacles.

E. When the machine is running, check the belt tension every 2000 hours. If the belt is loose, adjust it until the belt is tight; In order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil pollution in the whole process.

F every time the oil is changed, the oil filter must be changed at the same time.

G try to replace the parts with the original parts of the company, otherwise the supplier will not be responsible for the matching problem.

Clean the cooler

Every 2000 hours of air compressor operation, in order to remove the dust on the cooling surface, it is necessary to open the cover of the cooler purge hole on the fan bracket and purge the cooler with gas until the dust on the cooling surface is cleaned. Shang Ruo's radiating surface is seriously polluted and difficult to clean. You can unload the cooler, pour out the oil in the cooler, seal the four entrances and exits to prevent dirt from entering, then blow off the dust on both sides with compressed air or rinse with water, and finally dry the water stains on the surface. Put it back in place.

Remember! Don't scrape off dirt with hard objects such as iron brush to avoid damaging the surface of radiator.

Drain condensed water

The moisture in the air may condense in the oil-gas separation tank, especially in wet weather, when the exhaust temperature is lower than the air pressure, more condensed water will be precipitated. Too much water in the oil will cause emulsification of lubricating oil, which will affect the safe operation of the machine, such as:

1. Poor lubrication of compressor main engine;

2. The effect of oil-gas separation becomes worse, and the pressure difference of oil-gas separator becomes larger;

3. Causes the parts to rust.

Therefore, the condensed water discharge plan should be made according to the humidity.

Discharge method of condensed water

It should be carried out after the machine stops, there is no pressure in the oil-gas separation tank, it is fully cooled, and the condensed water is fully precipitated, such as before starting the machine in the morning.

① Unscrew the front plug of the ball valve at the bottom of the oil-gas separation tank.

② Slowly open the ball valve to drain water until the oil flows out, and then close the ball valve.

③ Screw on the front plug of the ball valve.

principle of operation

The safety valve has been set before the whole machine leaves the factory, and the supplier does not encourage users to adjust the safety valve privately. If adjustment is really necessary, it should be carried out under the guidance of the local labor safety department or the supplier's maintenance personnel to avoid adverse consequences.

Maintenance work suggestion

For general users, some compressor maintenance suggestions are provided for users' reference.

① Every week:

A. Check whether the unit has abnormal sound and leakage;

B. Check whether the meter reading is correct;

C. check whether the temperature display is normal.

② Every month:

A. check whether the machine is rusty or loose. If there is rust, remove rust, oil or paint, and tighten it loosely;

B. drain the condensed water.

(3) Every three months:

A. Clean the dust on the outer surface of cooler, fan cover and blades;

B, filling lubricating oil on the motor bearing;

C. Check whether the hose is aged and cracked;

D. check the electrical components and clean the electrical cabinet.

Compressor oil replenishment

In the running state, the oil level of the compressor should be kept between the minimum and maximum oil level. Too much oil will affect the separation effect, and too little oil will affect the lubrication and cooling performance of the machine. During the oil change cycle, if the oil level is lower than the minimum oil level, the lubricating oil should be replenished in time. The method is as follows:

(1) Stop the machine and wait for the internal pressure to be released (confirm that there is no pressure in the system), and then pull down the main power switch.

(2) Open the oil filler on the oil-gas separation tank and replenish proper amount of cooling lubricating oil.

③ Please refer to the regular maintenance table for the oil change time after the normal operation of the air compressor.
