Compressor lubricant
SCR screw compressor use different type of lubricant for different application. Each compressor unit is shipped with a lubricant label indicating the type of lubricant added to the unit. Different types of lubricants can adapt to the ambient temperature and load conditions are not the same, the oil change intervals are not the same. The SCR lubricant is specially designed for SCR compressor, in order to guarantee the safe and stable operation the compressor, we suggest that you use SCR genuine lubricant.
Do not mix oils of different types or brands as this can cause malfunctions, such as blistering of the oil, clogging of the filter, clogging of the orifice or plumbing, reducing the design life of compressors and lubricants.
When the compressor is running, check the lubricant level regularly. Each compressor is equipped with oil sight glass on the oil/air tank . The standard lubricant level should be in the green zone of oil mirror. If the level of the lubricant drops to the red zone of the oil sight glass after shut down, the unit needs to be refueled with lubricant, but only when the unit is shut down and drained completely.
Affect the life of the oil factors: ①Unusual high temperature operating temperature; ②Pollution; ③Other types or brands of lubricants; ④Strong oxidizing substances such as acids, sulfur, chlorides, nitrogen oxides, welding fumes, ozone; ⑤Ammonia; ⑥Solvent-type fumes; ⑦ Air dust.
Oil filter
The new compressor should be replaced after 600 hours of operation oil filter cartridge, after whenever the following conditions occur when the need to replace the oil filter. Replace the filter should be shut down, carefully wipe away dirt and oil from the outside, as much as possible to prevent impurities into the lubrication system.
■ At normal operating temperature filter (differential pressure) alarm, when the filter pressure exceeds 1.7 Bar (25psi).
■ Every 2000 hours of operation.
■ When changing the oil.
■ Each oil sample test failed.
Oil separator
The element is the overall structure, the oil mist can condense its surface into oil droplets, drip into the bottom of the separator, the oil return pipe is recycled back to the compression chamber. Handle the separator carefully to avoid damage. Once the separator core has been hit and deformed, even a little indentation will affect the separation efficiency resulting in excessive oil content in the compressor outlet, and even a tiny hole in the part will result in a very high oil content.
1.Under normal circumstances, if the air filter and oil filter properly maintained, oil separator does not require periodic replacement filter.
2.When the machine appears the following situation, need to replace the oil separator:
* The pressure difference before and after the oil separator is exceeded 1BAR.
* The oil content in the compressed air is still too high if it is determined that the oil level is normal, the loading and unloading are normal, and the oil return system is normal.
* Every 4000 hours.
Air filter
Air filters should be checked daily.
Clean the dust bag daily (for heavy duty air filters), clean the dust cap or intake silencer chamber. In dusty environments, clean-up should be done more frequently. If the ambient conditions are dirty, it is advisable to bring the compressor air intake to a source of clean outdoor air.
Whenever the air filter vacuum switch action, pressure loss up to 0.25BAR, the indicator light, the filter should be maintained; every 600 hours or three months should check the air filter for damage, air intake The system is not tight seal; under normal conditions of use, every 2000 hours of work or interval should be replaced air filter cartridge, if the environment is not good, more dust (such as ceramics, cement, etc.) should be properly reduced maintenance, replacement cycle.
Each time the air filter is serviced, check that the downstream side of the filter cartridge is dirty. If so, find out why and fix it. To ensure that the seal between the air filter and the compressor suction port, threaded connection, flange connection, leather pipe connection is absolutely reliable.
