鄭州巴特分析計(jì)量泵剛性介質(zhì)密封原理

鄭州巴特專業(yè)計(jì)量泵生產(chǎn)廠家，擁有數(shù)十年泵閥設(shè)備生產(chǎn)經(jīng)驗(yàn)，提供的計(jì)量泵設(shè)備具有高標(biāo)準(zhǔn)、高精度，滿足用戶生產(chǎn)需求。本文巴特計(jì)量泵廠家就具體闡釋計(jì)量泵剛性介質(zhì)密封原理。
聚氨酯灌注機(jī)中的計(jì)量泵的工作原理是通過(guò)交流伺服傳動(dòng)機(jī)構(gòu)推壓柱塞，將缸筒內(nèi)儲(chǔ)存的多元醇或多異氰酸酯壓出缸筒，使多元醇和多異氰酸酯的計(jì)量泵柱塞的運(yùn)動(dòng)行程成某一定比例，即多元醇和多異氰酸酯按某一體積比壓出，這樣來(lái)保證灌注時(shí)多元醇和多異氰酸酯的配比精度。這一運(yùn)動(dòng)過(guò)程中，產(chǎn)生了密封間隙與磨損的矛盾；一，為了保證配比的精度，減少液體泄漏，計(jì)量泵間隙應(yīng)越小越好；二，如果計(jì)量泵密封間隙太小，會(huì)帶來(lái)摩擦阻力增加，能量損失增大。因多元醇和多異氰酸酯是膠類材料，間隙小會(huì)造成粘缸現(xiàn)象，提高生產(chǎn)作業(yè)的難度。多元醇中通常含有石英砂添充料，間隙太小造成切削磨損或出現(xiàn)卡阻現(xiàn)象。所以，計(jì)量泵的剛性介質(zhì)密封間隙成為影響灌注機(jī)灌注精度的關(guān)鍵技術(shù)之一。
巴特國(guó)內(nèi)的多個(gè)省市地區(qū)擁有眾多的成功案例現(xiàn)場(chǎng)，根據(jù)用戶實(shí)際需求，帶領(lǐng)用戶參考考察；巴特根據(jù)用戶實(shí)際生產(chǎn)工況情況，提供佳的工藝方案。巴特提供計(jì)量泵設(shè)備包括：熔體計(jì)量泵、齒輪計(jì)量泵、紡絲計(jì)量泵等，詳細(xì)了解相關(guān)計(jì)量泵價(jià)格或者性能，請(qǐng)咨詢熱線：0371-67993077
