The use of screw air compressor life cycle is very long, generally in more than 10 years, but is not to say that after the purchase of the air compressor production, can be used.
Air compressor and other mechanical equipment, in use process need to do daily maintenance and maintenance, keep good operation to make the air compressor, effectively prolong its service life.
a, the service life of air compressor lubricants are generally about 2000 h, maturity must be replaced.
When change is not only to put the lubrication oil in the tank, also should be oil cut-off valve, oil cooler and residual oil is put in pipe line, to ensure that the newly added oil clean.
When choosing to pay attention to the quality of the lubricating oil, to pay attention to in the operation of the oil level, runtime oil level indicator must be in the right area, can not be too high nor too low;
Also needs to control the temperature of the lubricating oil, avoid water cut in oil.
2, regular inspection & other;
Run, run, drip, leak & throughout;
Compressed air leakage in most systems, 10%
The leakage is typical of between 25%.
If compressed air leak, then the unit will keep loading need to meet the requirements of pressure, will consume more power, result in the speeding up of the lubricating oil loss, need to add lubricating oil in advance.
3, regular add grease to motor, regular measure current, voltage, etc.
1% of three-phase voltage imbalance can lead to some current by more than 10%;
Three-phase voltage 3.
5% of the imbalance will increase the motor temperature 25 ℃.
So electric currents and voltages should be tested periodically, in order to reduce the production cost, improve the efficiency of the machine.
When wiring can't pick up the other motor, otherwise it will reverse, result in bearing damage or be killed.
4, regular replacement & other;
A / & throughout;
Screw air compressor are the using life of the a/(
General is 2000 h)
, after due to replace in a timely manner.
If you don't change, filter may be blocking even burst damage, make the temperature increase, performance degradation, cause other malfunction occurs, causing a greater loss.
5, check whether unit addition, unload anomalies, start-stop is abnormal, exhaust pressure with and without exception, etc;
Check to see if the vibration is too large, in the process of running any abnormal noise;
At the same time also note that the minimum pressure valve, temperature control valve, cut-off valve, whether a failure.
