離心泵的出口止回閥作用與選型離心泵出口的止回閥的作用就是防止出口管路中的液體倒流形成水錘造成泵內(nèi)葉輪損傷。止回閥的安裝與泵的多少無(wú)關(guān),止回閥主要為了在泵停止運(yùn)行后,防止液體回流,使泵倒轉(zhuǎn),從而造成損壞泵的事件,并且為了防止液體倒流對(duì)其他儲(chǔ)罐等的損壞(從高位罐倒流會(huì)造成罐補(bǔ)抽壞).因此好加上止回閥.如果能保證停泵前先關(guān)閉出口閥,且出口閥不內(nèi)漏或損壞.也可以不安止回閥.1.泵出口止回閥門"止回閥的選型一般的泵站工程情況，對(duì)于泵出口止回閥的選擇，應(yīng)遵循以下原則；對(duì)泵出口管路口徑較小的管路，即DN≤50mm時(shí)，應(yīng)選用升降式止回閥。對(duì)泵出口管路口徑DN＞50mm的管路，應(yīng)選用旋啟式止回閥旋啟式止回閥可以水平或垂直安裝。旋啟式止回閥閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)，其流體阻力一般小于升降式止回閥，它適用于較大口徑的場(chǎng)合，安裝位置不受限制，通常安裝于水平管路，它適用與較大口徑的場(chǎng)合。根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式、雙瓣旋啟式及多瓣旋啟式三種。單瓣旋啟式止回閥一般使用與中等口徑的場(chǎng)合。大口徑管路選用單瓣旋啟式止回閥時(shí)，安徽自吸泵離心泵生產(chǎn)，為減小水錘壓力，好采用能減小水錘壓力的緩閉止回閥，安徽自吸泵離心泵生產(chǎn)，安徽自吸泵離心泵生產(chǎn)。雙瓣旋啟式止回閥適用與大中口徑管路。對(duì)夾雙瓣旋啟式止回閥結(jié)構(gòu)小、重量輕。離心泵廠家就找靖江市瑞鑫泵業(yè)有限公司。安徽自吸泵離心泵生產(chǎn)</p><div
