The analysis of the corrosion in refinery low-pressure fluid seal gas holder reveals that the corrosion is mainly caused by the sour gas containing H_2S and CO_2, etc.
对炼油厂低压湿式螺旋气柜的腐蚀原因进行分析，结果表明：腐蚀主要是由H_2S和CO_2等酸性气体引起。
Safety seal: through the incorporation of a low specific gravity barrier fluid at a higher pressure than the pumped fluid, it guarantees a no leakage sealing action.
安全密封：通过并入比泵流体压力更高的低密度阻隔液，保证了没有泄漏发生。
The seal mechanism (10) is used for a fluid machine (p) to prevent a fluid from leaking out of a high-pressure space (h) into a low-pressure space (l) in the fluid machine (p).
密封机构(10)被用于流体机械(P)以防止流体从高压空间(H)泄漏进入流体机械(P)内的低压空间(L)。
