Attention: The above maintenance is subject to the time coming.
a. Lubricating oil specification and use
Lubricating oil has a decisive influence to oil-injection screw compressor. It will result in serious damage to
the compressor if it is used improperly or mistakenly. So please follow the regulations below.
1、
Please use the specific compressor oil.
2、 attention of use lubricating oil
2． 1、
Oil should comply with the requirements. Does not use mix the lubricating oil of different types, false
oil and generation oil. The brochure information of the machine has marked the type of the lubricating oil.
2．2、
Oil performance requirements are as follows: oxidation resistance, resistance to foam, corrosion and
abrasion resistance, separating with water strongly, viscosity, high flash point and low pour point.
2． 3、
Don't use the lubricating oil which is beyond its service life, or else lubricating oil quality declines and
then the flash point will also decline to burn the machine.
2．4、
Abide the oil changing period. Oil changing period accords the actual situation. It is suggested that
among the first two years, every 3 to 6 months, extracting oil samples to analyze the main indexes of
lubricating oil: viscosity, acid value, moisture, ash content, flash point and mechanical impurity, and to
determine actual oil changing period, for no waste.
2 ． 5 、
After using the compressor two years later, it would be best to use lubricant oil for a "system
cleaning". The way is that continuously changes oil two times, the first work for 6 hours and then the
second change.
Check whether the thermostatic valve works normally. When the light
of the oil-air separator pressure indicator turns on, or oil pressure is
higher than the air pressure, check and replace the oil-air separator(in
poor environment, its time will be shortened). Clean the cooler. Add
grease to motor bearing.
Replace air filter, oil filter and oil. When the light of the oil-air separator
pressure indicator turns on or oil pressure is higher than the air
pressure, check and replace the oil-air separator. Clean the cooler.
Replace
Nylon tube, belt, oil meter, solenoid valve, O ring.
Replace the bearing, the shaft sealing, sound insulation sponge and
rubber tubing (Deal with them according to the specific situation).
