延長(cháng)高(gāo)粘度齒輪泵的(de)壽命（一）

輸送介質有著(zhe)傳遞、潤滑、密封和(hé)傳熱(rè)的(de)特性。因此高(gāo)粘度齒輪泵具備了(le)功耗低、洩漏少、流量多(duō)等優點。

Transmission medium has a transmission, lubrication, sealing and heat transfer characteristics. Therefore, high viscosity gear pump equipped with low power consumption, less leakage, flow more and so on.

介質流動的(de)難易程度充分(fēn)體現了(le)液體的(de)粘度，粘度一旦過高(gāo)便會增加内摩擦阻力，使輸出功率降低，并造成能量浪費，從而造成系統溫度過高(gāo)。

Medium degree of difficulty fully reflect the flow of the liquid viscosity, viscosity will be increased once the high frictional resistance within, so that the output power down, and cause energy waste, resulting in system temperature is too high.

當輸送介質确定了(le)以後，應按照(zhào)産品說明(míng)書(shū)上的(de)指示操作，避免使用(yòng)超出廠家推薦的(de)流體介質的(de)範圍，時(shí)刻注意系統的(de)工作溫度牢記它的(de)使用(yòng)範圍。如果輸送介質的(de)粘度指數高(gāo)一些也(yě)可(kě)在某一較寬的(de)溫度範圍内使用(yòng)時(shí)。還(hái)要考慮到輸送液體的(de)粘度較高(gāo)或系統在寒冷(lěng)環境中流暢性，确保輸送介質的(de)凝點應該低于預期的(de)最低作業溫度；以及所要輸送的(de)介質是否與系統中的(de)密封、墊圈、軟管等橡膠材料具有相容性，若不相容應重新選擇介質。

When the transmission medium identified, they shall be in accordance with the instructions on the product manual, to avoid exceeding the manufacturer"s recommended range of fluid medium, keep in mind bear in mind the system operating temperature range of its use. If the transmission medium viscosity index may also be higher in a wide temperature range of use. Also take into account the viscosity of the liquid delivery system, a higher or fluency in a cold environment, to ensure the transmission medium freezing point should be lower than the expected minimum operating temperature; as well as to whether the media delivery system, seal, gaskets, soft - piping and other rubber materials have a compatible, if the incompatibility should be re-selection medium.
