Answer: the main parts of the color coated coil pneumatic system are pipeline, filter, pressure reducing valve, oil mist device, solenoid valve and cylinder. The central task of maintenance is to ensure the supply of clean and dry compressed air to
the pneumatic system; Ensure the necessary lubrication of oil mist lubricating elements; Ensure that the pneumatic components and system can meet the specified working conditions (such as pressure, flow, voltage, etc.); Ensure the airtightness of pneumatic
system; Ensure that the actuator works according to the predetermined requirements.
The maintenance of color coating coil can be divided into routine maintenance and regular maintenance
The main task of daily maintenance is to discharge condensate
water and check the operation of lubricating oil and air compressor system. Condensate discharge involves the whole pneumatic system, including air compressor, aftercooler, air tank, air filter, dryer, piping system, etc. At the end of the work, the condensed
water should be discharged to prevent the freezing of the condensed water caused by the temperature lower than 0 ℃ at night. As the temperature in the pipe drops at night, condensate will be further separated out. Therefore, before the pneumatic device
works every day, condensate should be discharged. Pay attention to check whether the automatic drainer works normally, and there should be no excessive water in the water cup. When the pneumatic device is working, check whether the lubrication of the
oil mist device meets the requirements (generally, the oil drop is not less than 5 drops / min), and the oil should not be mixed with dust and moisture. The daily management of the air compressor system is: whether the cooling water is provided to the
rear cooler (refers to the water-cooled air compressor); Check whether the air compressor has abnormal sound and heating, and whether the lubricating oil level is normal.
