德國BOSCH內(nèi)嚙合齒輪泵生產(chǎn)的支撐塊浮動式內(nèi)嚙合齒輪泵，內(nèi)外齒輪均采用修正漸開線齒形，用活動月牙板將高、低壓腔分開，并在徑向形成壓力補(bǔ)償，使得內(nèi)外齒齒頂與月牙板之間形成幾無間隙的密封，軸向動補(bǔ)償盤則保證軸向間隙的良好密封，使得該泵的內(nèi)泄漏減至zui低。低壓12Mpa、中壓21 Mpa、高壓33 Mpa。此結(jié)構(gòu)容積效率高、結(jié)構(gòu)復(fù)雜，制造成本高。他適用于輸送各種輕質(zhì)、揮發(fā)性液體，直至重質(zhì)、粘稠液體，甚至半固態(tài)液體。廣泛應(yīng)用于石油、化工、油脂、涂料等行業(yè)。
