Some aspects of the use of screw air compressors during the Chinese New Year should be noted:
Chinese New Year usage
If your screw air compressor is powered by electricity, since the oil viscosity of the lubricating oil parts of the machine is relatively high when it is just started, and the voltage in some areas may be low, it is very easy to cause relatively difficult to start when it is just started. Generally, the air compressor is rotated 2-3 times, the air compressor is activated 3-4 times, and the pipe between the air compressor and the air bag is removed or an exhaust valve is removed. After the equipment is started, the empty machine runs for 10 minutes, stops, and then the removed parts are installed and restarted. In addition, pay attention to the measurement of the current at work (under normal circumstances, the working current is within the range of ± 5% of the rated current). In addition: pay attention to timely replacement of lubricating oil.
After shutdown, pay attention to vent all gas, sewage, waterproof, and empty the water, gas and oil in various pipelines and gas packets. This is because the temperature difference between the screw air compressor and the shutdown is relatively large under zero conditions, and after the shutdown for a period of time due to the low temperature is very easy to produce condensate, and then ice, which is easy to cause the control pipeline, intercooler blockage, air bag expansion and other failures.
Especially water-cooled air compressors and water-lubricated air compressors, draining clean water is the key.
Spring Festival cleaning chapter
As we all know, the use of air compressors for a long time, there will be carbon, grease, rust, sediment and so on; Or have used different brands, types of air compressor lubricating oil, there will be glue. These are harmful to the normal operation and service life of air compressors. Before the New Year, everyone will clean up personal hygiene, family hygiene, and environmental hygiene, so in order to ensure the stable and efficient operation of the air compressor, how should the air compressor be cleaned?
1, first open the air compressor, let it run for a few minutes, so that the oil reaches normal temperature;
2, then close the air compressor, and disconnect the main circuit switch. After the internal pressure is discharged, open the refueling cover and pour the air compressor cleaning agent;
3, tighten the refueling cover, open the air compressor and run for 30 minutes;
4. Put off the old lubricating oil and add the new air compressor lubricating oil; When changing the lubricating oil, the oil filter must be replaced at the same time;
5, remove the dust on the surface of the radiator, the air gun can be used to purge the dust on the surface of the cooler.
The steps of air compressor cleaning are basically like this, and it is necessary to follow the product instructions and operating steps when cleaning.
Chinese New Year Holiday
It's Chinese New Year. People go home for the holiday. Your air compressor has been tired for a year, but also have a rest in the air compressor room. What should you pay attention to when you rest?
1, replace the lubricating oil for the screw air compressor before deactivation, and run for 30 minutes. After two or three days, exhaust the condensate water in the oil and gas drum, aftercooler and oil cooler.
2. Close all the openings of the screw air compressor to prevent moisture and dust from entering.
3, the screw air compressor controller, distribution box and other electrical equipment, with plastic paper or oil paper wrapped to prevent moisture intrusion.
4, as far as possible to move the screw air compressor to a place with less dust and dry air storage.
5, if the screw air compressor itself has some minor faults, the fault should be completely repaired. One is to avoid worsening the fault, and the other is to facilitate future use.
Annual commencement
After the year, the temperature is still relatively low, the air compressor will be difficult to start after a long time of shutdown, in order to successfully boot, pay attention to the following points:
1, the air compressor should ensure that the air compressor oil temperature is not less than 5℃ before starting, if the temperature is too low, please use a heating device to heat the oil separator and the main engine part.
2, check that the oil level is in the normal position, check that all condensate drainage outlets are closed, and check that the cooling water discharge outlet is closed for the water cooling unit.
3, the manual disc drive the host coupling rotation is flexible, for the difficult disk drive unit, please do not blindly start, should check whether the host fault, lubricating oil is viscous failure, troubleshooting can be started.
4. The air compressor with a long downtime should be replaced with a new oil filter before its initial start to reduce the resistance and insufficient oil supply caused by viscous oil.
5, it is best to start the unit several times, after the formal start should check the current and oil temperature changes, if there is a sudden change in temperature, please stop immediately, for the heat recovery unit should be closed before the start of the heat recovery system on the oil side of the valve, such as the unit normal opening temperature rises to the normal range and then slowly open the heat recovery system.
For the unit with sudden temperature change or high temperature jump, remember not to start repeatedly, open the intake valve, fill the host with the right amount of lubricating oil, and start the host again after the disc is flexible.
