                  第一部分 概述

                  Chapter One    General Introductions

                  1.術語Terminology

                       粘度:液體受外力作用移動時,液體分子間產生內摩擦力的性質,稱為粘度。

                       ViscosityFlow of a fluid under external forceinner friction between molecular called viscosity.

                  運動粘度:指在某一恒定溫度下,測定一定體積的液體在重力下流過一個標定好的玻璃毛細管粘度計的時間,粘度計的毛細管常數與流動時間的乘積,即為該溫度下測定液體的運動粘度。在溫度t時運動粘度用符號Vt表示。

                       Kinematic viscosity: Under a given hydrostatic temperature, test the time which a fixed volume of fluid flow through glass capillary viscometer, the product of capillary coefficient and flow time namely the liquid kinematic viscosity under the temperature. “Vt” stands for viscosity at“t”temperature.

                       動力粘度:某溫度下運動粘度和同溫度下液體的密度之積為該溫度下液體的動力粘度。在溫度t時的動力粘度用符號ηt表示。

                       Dynamic viscosity: under the same temperature, the product of kinematic viscosity and liquid density is the dynamic viscosity, it is indicates by the symbol “ηt”.

                  意義:粘度是絕緣油的重要指標之一,使用于變壓器的絕緣油,在不影響油品其他指標(如閃點)的前提下,粘度盡可能的低一些為好,因為粘度越低,變壓器的循環冷卻效果越好;同時粘度也是潤滑油的最重要指標之一,因為潤滑油的牌號大部分是以油品標準中的運動粘度的平均值來區分的,另外正確的選擇一定粘度的潤滑油,可保證發電機和汽輪機組穩定可靠的運行狀態,粘度過大或過小都會改變發動機的功率,增大燃料的消耗,增加機器磨損等;

                       Significance: viscosity is one of important index of insulating oil, the viscosity of the transformer insulating oil should as lower as possible, because the lower viscosity, the better circulating cooling effects of transformer; meanwhile, it is one of important index of lubricant oil, the number of lubricant oil generally distinguished by the average of kinematic viscosityin addition, proper choose of viscosity of lubricant oil will guarantee stable running of generator and turbine sets, viscosity is too higher or lower will change the power of generator, increase fuel consumption and wear etc.

                  4 試驗步驟Procedures

                  4.1根據測定溫度的要求在浴缸內注入相應的浴液體至水位標記處。

                  According to measure temperature required, pour relevant bath liquid into the bath vat until it reached the marked level

                  4.2開機。Start up

                  4.3在“設置”菜單中根據樣品性能設置所需要的參數。

                  Under “setup” menu, according to samples performance, set the required parameters.

                  4.4安裝試樣:往內徑符合要求且清潔、干燥的毛細管粘度計內裝入試樣。在裝試樣之前,將橡皮管套在支管上,并用手指堵住管身的管口,同時倒置粘度計,然后將管身插入裝著試樣的容器中,這時利用橡皮球將液體吸到標線,同時注意不要使管身,擴張部分中的液體發生氣泡和裂隙。當液面達到標線時,就從容器里提起粘度計,并迅速恢復其正常狀態,同時將管身的管端外壁所沾著的多余樣擦去,并從支管取下橡皮管套在管身上。

                  Setup Sample: fill the samples into the cleandry suitable inner diameter capillary. Before setup the sample, cover the rubber casing on the branch tubes, jammed the nozzle with finger, meanwhile inverse the viscometer, then immerse the body into the container with samples, at this time sucked the liquids to the marked line with the rubber ball, beware of the liquids in dilated parts created air bubbles and gaps. When the level reached the marked line, pulls the viscometer out of the container, quickly restore its normal state, at the same time rub off the extra samples adhered to the external wall of tube end, and remove the rubber casing from the branch tubes and cover for the tube body.

                  4.5將粘度計管固定在粘度計管架上,并裝入水浴中。

                  Fixed the viscometer tube to the rack, and immerse it into the water bath.

                  4.6當實測溫度到達設定溫度后開始測試。利用毛細管粘度計管身口所套著的橡皮管將試樣吸入擴張部分,使試樣液面稍高于標線,并且注意不要讓毛細管和擴張部分的液體產生氣泡或裂隙。此時觀察試樣在管身中的流動情況,當液面正好回落到上標線時,按對應的“數字”鍵開始計時,液面正好回落到下標線時,再按對應的“數字”鍵停止計時,屏幕顯示本次試驗的運動時間。上次運動時間顯示后方可進行下一次的吸油,待第四次檢完后,屏幕除顯示四次運動時間外,儀器自動計算并顯示平均時間及最后的粘度結果。

                  Begin to test as the measured temperature reached the setting temperature. Make use of the rubber casing covered on the viscometer nozzle to draw the samples into extension parts, make the sample level more high than marked line, and prevent the liquids from air bubbles and gap. At this time, observe the flow condition of samples, when the level return to the upper marked line, click corresponding “number” key start to timing, when the level return to the lower marked line, click corresponding “number” key stop timing, the screen displayed the flow time of this test. The next extraction of oil can be conduct after displayed the last flow time, when completed four test, the apparatus automatically calculate and display average time and the last viscosity but displayed flow time of four tests.

                  4.7實驗結束后,對粘度計管進行清洗,并放在固定位置以便下一次試驗。

                  After experiment, clean up the viscometers and put it in a fixed location, so as to the next experiment.
