6.1.4 Matters needing attention in the use of Lubricating Oil
1) If the micro-oil screw air compressor is used for the first time, it is difficult to determine the
time of oil exchange. After 1000 hours of oil use, the oil samples can be sent back to our company
for oil testing to determine the quality of lubricating oil. Then repeat it every 1000 hours. After a
few times, the period of oil exchange of the air compressor can be determined without wasting oil.
2) Never allow the lubricating oil to exceed the service life of the oil, and the oil should be
replaced on time, otherwise, the quality of the oil will decline and the lubricity will be poor, which
will easily cause the phenomenon of high temperature tripping, and at the same time, the ignition
point and the oxidation resistance of the oil will decline. It is also easy to form oil spontaneous
combustion and the event of air compressor burning.
3) After two years of operation, the air compressor had better do a "system cleaning" with
lubricating oil. The method is to replace the lubricating oil immediately after the air compressor has
been running for 6-8 hours when the new lubricating oil is replaced. The residual organic
components of the original system can be cleaned, and more lubricating oil can have a better
service life.
6.2 Replacement of belts
If the belt is used for too long, for more than 20000 hours, or for
serious wear, the belt shall be replaced:
1) When changing belts, all belts should be replaced in one place, and
only one belt should not be replaced, otherwise the tension will be
unbalanced.
2) Be careful not to splash the lubricating oil on the belt or pulley.
6.3 Pressure system adjustment
1) System pressure adjustment
System pressure has been set before the factory; generally do not
need to adjust. Unloading and loading pressures can be modified in user parameters within the
controller.
