These tanks maintain system pressure below the relief setting of the relief valve. 這種膨脹罐將系統壓力保持在安全閥設置的排放壓力以下。
With the compressor clutch engaged, record the discharge air temperature and the compressor discharge pressure. 當壓縮機離合器合上時(shí)，記錄排放空氣溫度和壓縮機排放壓力。
Irrespective of disconnection of a fan, control of the exhaust steam pressure, must be maintained. 必須保持風(fēng)機不被無(wú)端的斷開(kāi)，排氣壓力在控制之下。
Low table by adjusting the outlet pressure control screw. 低壓表的出口壓力可由調節螺桿控制。
Like the single-stage regulator, outlet pressure from the first stage of the two-stage regulator rises as cylinder pressure decreases. 同單級調整器一樣，兩級調整器的第一級的出口壓力隨鋼瓶壓力的降低而升高。
The dial records showed a very slight variation in pressure. 刻度盤(pán)顯示出壓力有極微小的變化。
