Lugkompressor in die winter of 'n lang tyd na die afskakeling van die kofferbakkennisgewing

Time: 2020-09-04 09:47:08

In the cold winter, if you do not pay attention to the maintenance service, it will cause air compressor failure. Therefore, in the winter, because of a long time of shutdown, during the period of not doing anti-freeze protection, resulting in the cooler freeze crack and start the body failure is not rare

Matters needing attention of oil injection air compressor in winter

1.Before starting the air compressor, make sure the oil temperature is no less than +2 degrees. If the temperature is too low, please use the heating device to heat the oil and gas barrel and the main engine
2.Check that the oil level is in the normal position, check that all condensate outfalls have been closed (open for long-term shutdown), and check whether the cooling water outfalls have been closed (open for long-term shutdown).
3.After the power is cut off, the manual disk-operated main engine coupling should be applied, which should be flexible in rotation. For the body with difficulty in disk-operated, please do not start blindly, but check whether the body or the motor has faults, whether the lubricating oil is viscous and fails, etc. The machine can be started after troubleshooting
4.For machines that have been shut down for a long time or whose oil filter has been used for a long time, it is recommended to replace the oil filter before starting up, so as to prevent the failure of the machine caused by the lack of oil supply due to the reduced penetration of oil filter by viscous oil products at the beginning of starting up
5.After the above work inspection, start the machine with a little movement for the first time, check the operation condition and whether the sound of the machine is normal when starting. If the temperature changes suddenly, stop the machine immediately for inspection. Do not start the machine frequently
6.If the heat recovery machine has been installed, please close the oil valve of the heat recovery system, and then slowly open the oil control valve of the heat recovery system after the normal operation of the unit
7.Two stage compression machine especially high-power models, stop up again after a period of time in air inlet adding suitable amount of lubricating oil and move for 2-3 times, and the barrels of oil and gas to the body of oil dampers in just started to all open, running stable after such as the temperature was low, the adjustable customers into the water to control the temperature of the cooling water valve, if necessary according to the actual temperature conditions, by adjusting the oil valve to control the exhaust temperature of input to the right
8.Frequency conversion machine to idea in the winter exhaust temperature, prevent too low (mainly a long time low frequency operation caused by exhaust temperature too low), according to the exhaust temperature regulation of the appropriate cooling water valve opening, if really necessary can be replaced for high temperature type heat control valve core, to avoid emulsification of oil products

Notes for oil-free air compressor in winter

For oil-free air compressors, in winter, especially when the machine stops for a long time and starts up, the following matters should be noted. Please be sure to inform each service personnel and customer equipment personnel
1.During the shutdown, if possible, the compressor should be provided with some form of heating, if not possible, should try to use plastic cloth or other shelter to block the compressor, prevent the wind and snow erosion
2.When the air compressor unit is working, the temperature is relatively high; After downtime, due to the ambient temperature is low, there will be a lot of condensate, exists in the pipe, if not timely discharge in the winter cold weather may cause jams frosty ice air compressor exhaust pipe and other equipment, so in winter, stop after cooling air compressor, it is important to note that empty all gas drainage water, the liquid water in the vent pipe in a timely manner
3.If is a water-cooled machine, please vent the water in the cooling water pipe network. Some machine will open the drain and sewage of the cooler. Some machine will open all the drain and sewage valves of the intercooled and post-cooled machines and open the drain valve of the air-cooled machine in the same way to discharge the liquid water in the cooler
4.After the shutdown of the machine, please turn off the power and open the drain valve, and try your best to press the arrow to the direction of the fast disc coupling, so that the machine can turn quickly and the water in the machine can be discharged as far as possible
5.Before starting the machine for the first time after vacation, please check whether all kinds of valves ZW machine opened before vacation are working normally before starting (power off) (prevent water in the machine from forming ice blocks and freezing the star wheel). You can start machine after there is no abnormality. Similarly, you also need to start the machine after turning the machine on after normal operation
6.Before starting the machine for the first time after vacation, please check whether all kinds of valves machine opened before vacation are working normally before starting (power off) (prevent water in the machine from forming ice blocks and freezing the star wheel). You can start machine after there is no abnormality. Similarly, you also need to start the machine after turning the machine on after normal operation
7.Automatic operation of air compressor is not recommended in extremely cold environment
