供應卸載功能單向閥 可根據要求設計

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。

sk automatic control system instruction

sk is a system of controlling the value of pressure of medium fairl and composed

0f the pressure control switch and the discharge check valve it has the properties of small size，high precision and low weight and，certainty，is

shockprool moisture—proof and explosion—proof

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

meter and keeps the pressure in the air compressor tank 1n the desired range

the discharge check valve purges the air in the inlet tube automaticallv as soon

as the air compressor stops，to make the electric nlotor restart easily from heavy

load.

principle：the sk is fixed on the air tank and the pressure in the tank directly

acts 013 it according to cut—in and cut—out limits 0f the tank pressure it turns on

or 0ff the electric motor of the air compressor keeping the pressure in the air

compressor tank in the desired range.
