FR-E740-1.5KSC

FR-E740-1.5KSC油封密封是一種自緊式唇狀密封，其結(jié)構(gòu)簡(jiǎn)單，尺寸小，成本低廉，維護(hù)方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對(duì)磨損有的補(bǔ)償能力，但不耐高壓，所以一般用在低壓場(chǎng)合的化工泵上。

化工泵在與運(yùn)轉(zhuǎn)時(shí)，副葉輪所產(chǎn)生的壓頭平衡了主葉輪出口高壓液體，從而實(shí)現(xiàn)密封。停車時(shí)，副葉輪不起作用，因此同時(shí)配備停車密封裝置解決停車時(shí)可能產(chǎn)生的化工泵泄漏。副葉輪密封結(jié)構(gòu)簡(jiǎn)單、密封可靠、使用壽命長(zhǎng)，化工泵運(yùn)轉(zhuǎn)中可實(shí)現(xiàn)滴水不漏，因此在化工泵輸送含雜質(zhì)介質(zhì)的泵上經(jīng)常采用。
