武研銷(xiāo)售WRY系列/臨沂萊蕪+常州市武研熱油泵有限公司+WRY系列常州武進(jìn)高溫導(dǎo)熱油泵要預(yù)熱的原因有:
(1)溫度高
(1) high temperature
熱油泵一般溫度在200~350℃左右,如不預(yù)熱,泵體涼,熱油進(jìn)入后,因冷熱差異大,食使泵經(jīng)受不住這種劇烈的變化,引起泄漏、裂縫、部件受損和零件因熱脹系數(shù)不一樣,而使兩個(gè)零件脹住等等。
The general temperature of hot oil pump in the 200 ~ 350 DEG C, such as preheating, pump body cool, into the hot oil, because of the differences of heat and cold, eat the pump could not withstand such drastic changes, causing leakage, cracks, damaged parts and components by the coefficient of thermal expansion is not the same, and the two parts bulging live and so on.
(2)粘度大
(2) viscosity
熱油泵輸送的介質(zhì)粘度都較大,在常溫下和低溫下會(huì)凝固,甚至把泵體管線凝死,而造成啟動(dòng)不上量,流量、揚(yáng)程小,并會(huì)使泵產(chǎn)生振動(dòng)和雜音。
Heat pump transmission medium viscosity are larger, at room temperature and low temperature will be solidified, and even the pump pipe line to die, and cause no amount of start-up, flow, head small, and will make the pump vibration and noise.
