隨著水泵工作狀態(tài)時(shí)刻變化和工作周期的增長(zhǎng)，填料的磨損程度逐漸加大，即填料與軸的間隙越來(lái)越大，從而導(dǎo)致軟填料密封的泄漏增加，因此總是通過(guò)人工調(diào)節(jié)壓蓋螺栓來(lái)調(diào)節(jié)填料的預(yù)緊力。為了增大軟填料密封的壽命，經(jīng)過(guò)仔細(xì)的實(shí)驗(yàn)研究得出如下三種改進(jìn)方法：種就是將金屬環(huán)，軟填料環(huán)，圓柱形彈簧交替組合安裝，通過(guò)分別調(diào)節(jié)各層軟填料環(huán)的壓縮力，從而得到佳的徑向應(yīng)力分布。為此在制作填料時(shí)往往需要浸漬填充各種潤(rùn)滑劑和填充劑第二種是將一組軟填料環(huán)安裝在一個(gè)可以軸向移動(dòng)的金屬套筒中，將圓柱形彈簧安裝在壓蓋螺栓內(nèi)，通過(guò)調(diào)節(jié)壓蓋螺栓來(lái)調(diào)節(jié)預(yù)緊力。第三種是將金屬環(huán)和填料環(huán)做成不同規(guī)格，使金屬環(huán)和軟填料沿填料涵底方向逐漸減小，從而在壓蓋的作用力下，軟填料的徑向應(yīng)力相應(yīng)逐漸增加，使得徑向應(yīng)力獲得合理分布。②關(guān)于軟填料環(huán)的圈數(shù)設(shè)計(jì)問(wèn)題，一般其圈數(shù)在至圈為宜。③軟填料的材質(zhì)選擇問(wèn)題，其原則是：一是有一定的彈塑性，當(dāng)水泵填料受軸向壓緊時(shí)能有一定的補(bǔ)償能力追隨性;二是有一定的強(qiáng)度，使水泵填料不至于在未磨損前先損壞;三是化學(xué)穩(wěn)定性高，不被流體介質(zhì)腐蝕和溶脹，同時(shí)也不污染介質(zhì);四是不滲透性好，對(duì)填料的組織結(jié)構(gòu)致密性要求高。懷化格蘭富機(jī)械密封件TP125-420/4</p></p><br
