4.3.3 when the machine is not in use and there is no staff to take care of it, the power
must be unplugged to avoid causing fire.
4.4 lubricating oil :(special oil for air compressor)
4.4.1 compressor lubricants are generally of high quality and contain antioxidants, not
easy to oxidized and thickened, not foaming, and low carbon residue, high flash point
is the most ideal, due to a wide variety of compressor lubricants, usually choose
l-dab100 (winter), l-dab150 (summer).The optimum operating temperature of the air
compressor oil is between 5
℃
and 25
℃
.
4.4.2 the oil level shall be kept within the red circle line in the middle of the oil-closing
mirror or the amount of oil shall be added as required by the label.
4.4.2.1 too much oil hinders the normal operation of the machine, or even causes
burning.
4.4.2.2 if the oil quantity is too much, unnecessary waste will be caused, and the
exhaust valve will accumulate carbon and damage the whole machine.
4.4.2.3 please pay attention to refueling when the air compressor stops running.
4.4.2.4 please pay attention to the quality of lubricating oil (such as the cleanliness and
viscosity of lubricating oil), do not use thick lubricating oil or other miscellaneous oil,
waste oil.
4.5 temperature description
4.5.1 the normal operating environment temperature of air compressor is between -5
℃
and 35
℃
, and the altitude shall not exceed 2000 meters.
4.5.2 when the suction pressure of the air compressor is 0.1mpa (absolute pressure) and
the final exhaust pressure is the rated exhaust pressure under the normal operating
environment temperature, the actual exhaust temperature of the air compressor shall not
exceed 200
℃
single-machine compression, and the two-stage compression shall not
exceed 180
℃
, and the lubricating oil temperature in the crankcase shall not exceed
70
℃
.
