How to maintain air dryer?

Bảo dưỡng máy sấy khí như thế nào? Kiểm tra xe ống thoát khí, thoát nước hình chữ U có thoát khí nén và nước cứng bình thường không. Hãy dọn dẹp một tháng hơn một lần ống thoát hình chữ U. Kiểm tra xem có bộ phận nối ống nào bị rò rỉ không. Hãy duy trì cách ổn định nhiệt độ bên trong ( dưới 38oC) và nhiệt độ cửa vào khí nén ( dưới 38oC). Đồng thời phải dọn dẹp theo chu kì để bụi, tạp chất không phủ lên tụ điện của bộ làm mát sau và máy sấy khí ( cách khoảng 1-2 tuần)

Atmospheric air always contains moisture: the higher temperature, the higher humidity is typical for the air. However, when compressed air is accumulated moisture, the water is condensing on the internal parts of the equipment and pneumatic systems. It is the case of corrosion and reduce the equipment lifetime. Therefore usually the additional air treatment equipment, like air dryer are used to avoid the accumulation of moisture in the pneumatic system.

Line 2: discharge temperature .
Line 3: total operation hours .
Line 4: date(YY.MM.DD HH:MM .

If any fault is found in a compressor after turning on Micom, it displays alarm and trip; or, it shows the above display.

1) To remotely control load/no-load operation of a compressor, connect the switch as presented in the above TB2.
2) No load operation: no load operation is allowed if connecting +24 terminal to 104 terminal.
3) Load operation: load operation is allowed if +24 terminal is not connected to 104 terminal.

* The operation/stop can be controlled by Micom’s controller even during remote operation.
