sk系列氣壓開關說明書

sk是一種依隨被控介質《空氣》的壓力升降而控制電路閉合或斷開的開關。由壓力控制開關和卸荷單向閥組成。其體積小、控制精準度高、重量輕、防爆、耐震、防潮。

用途：sk系列氣壓控制開關主要用於排氣量1立方米以下微型空氣壓縮機之壓力自動控制：調節壓縮機儲氣桶中的空氣壓力，使之在預設的壓力值間運轉。卸荷單向閥在停機時自動卸荷壓縮機及進氣管內壓縮空氣，保證電機與壓縮機不受氣壓負荷作用，易於從新啟動和連續使用。

原理：本產品安裝於壓縮機儲氣桶（管）上，儲氣桶中的空氣壓力直接作用在氣壓控制開關：依據預設的上下限壓力與帶寬接通或斷開電動機的啟動、運行及停止，使空氣壓縮機之輸出氣壓介於預設的範圍內。

purpose：skis primarily used for the micro air compressor under 1cubic

meter and keeps thepressure in the air compressor tank 1n the desiredrange
