The screw air compressor must be maintained regularly. If you do not maintain regularly, what will be the result? The editor gave what kind of dangerous accidents: "The screw air compressor must be maintained regularly, otherwise the danger is abnormal!
Unplanned maintenance consequences
Untimely soot blowing and replacement of air filter elements can cause: blockage, reducing air intake and exhaust. It can also cause increased negative pressure and pressure, contaminants entering the machine, oil filter clogging, oil separation core clogging, cooling lubricant deterioration, and host wear.
Unplanned oil filter replacement: When the pressure difference increases, the excess oil decreases, and the main engine exhaust temperature rises and stops. If the pressure difference between front and rear is too large, pollutants enter the machine, block the oil separator, and the main engine is worn.
Do not replace the oil separation core: As the pressure difference between the front and rear increases, the main motor current increases, which also reduces the oil discharge. If the pressure difference between the front and rear is too large to decompose, the cooling oil will enter the pipe with the air until exhaust, and the exhaust temperature of the main engine will rise and stop.
Pipe fittings are not clean: When blocked, a small amount of oil and air enter the pipeline, causing oil loss and oil shortage.
Add butter to the main motor bearings from time to time: the bearings wear out until the main motor burns out.
It can be seen that the maintenance of the screw air compressor is still like a car and should be routinely maintained after a period of time. The air compressor is well maintained and can serve you better. Just like the long-term work before, the owner gave him enough food and he worked hard for you.
Daily maintenance
Check the oil level, check the air filter and coolant level, check the hoses and all pipe joints for leaks, check whether the consumable parts have reached the replacement cycle, must be closed for replacement, and check whether the exhaust temperature of the main engine is reached Or close to the high temperature alarm value. In order to check the pressure difference of the separator, the oil cooler must be cleaned. When the pressure difference is 0.6 bar or higher (the limit is 1 bar) or the pressure difference starts, the separation core should be replaced.
2. Monthly maintenance
Check the cooler, clean if necessary, check all wiring and tightening, check the AC contactor contacts, clean the dust on the surface of the motor vacuum cleaner and housing, clean the oil filter, check the air compressor settings and operation.
3. Quarterly maintenance
Clean the main motor and fan motor, replace the oil filter element, clean the cooler, check the minimum pressure valve, safety valve and sensor.
4. Annual maintenance
Replace the oil and "oil separator" filter element, replace the air filter, oil filter, safety valve inspection, check the elastic coupling, check the cooling fan, clean the automatic drain valve, add or replace the motor grease.
