Sung Shin - VSD air compressor

18/02/2019

Variable Frequency Driver (VFD) -reducing energy consumpsion system is produced with the required amount of air and compressor shutdown under no-load conditions. In order to minimize unnecessary energy loss through the inverter to adjust the number spin of compressor Energy consumption saving arises starting by reducing the starting current as the inverter is operated.

How to maintain air dryer?

26/12/2018

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)
