【摘要】：本課題通過查閱大量的文獻(xiàn),對潤滑脂相關(guān)理論知識進(jìn)行了系統(tǒng)學(xué)習(xí),搭建了試驗臺,通過在高壓噴射狀態(tài)與低壓流動狀態(tài)下對五種不同鋰皂纖維含量的通用鋰基潤滑脂與壓力損失的關(guān)系進(jìn)行實驗研究,得出了潤滑脂皂纖維含量對壓力損失的影響規(guī)律。潤滑脂是一種性質(zhì)極其復(fù)雜多變的物質(zhì),所以本文首先對潤滑脂的理化性質(zhì),結(jié)構(gòu)組成,流變特性,流變方程以及管道內(nèi)流動特性等等進(jìn)行了深入的理論研究。然后設(shè)計實驗原理圖,同時進(jìn)行壓力變送器進(jìn)行標(biāo)定實驗,學(xué)習(xí)管路連接知識,設(shè)計管路連接方案,并用SOLIDWORKS進(jìn)行實驗系統(tǒng)管路連接的三維建模,并最終根據(jù)實驗原理圖搭建試驗臺。在潤滑脂輸送特性的試驗中,通過在室溫下,對含有不同皂纖維含量的00#、0#、1#、2#以及3#五種通用鋰基潤滑脂在高壓噴射狀態(tài)與低壓流動狀態(tài)下的壓力損失規(guī)律進(jìn)行研究,并對測得的數(shù)據(jù)利用MATLAB擬合曲線,得到兩種狀態(tài)下壓力變化曲線和壓力損失變化曲線,從中得到如下結(jié)論:(1)高壓噴射狀態(tài)較低壓流動狀態(tài)壓力波動大,且隨著皂纖維的增多,幾種脂在高壓噴射狀態(tài)下工作壓力不斷增加,并在3號鋰基脂處工作壓力達(dá)到最大,達(dá)到 18.7MPa。(2)無論在高壓噴射狀態(tài)還是低壓流動狀態(tài)下,隨著皂纖維含量的增加,壓力損失ΔP呈現(xiàn)上升趨勢。(3)無論在高壓噴射狀態(tài)還是低壓流動狀態(tài)下,潤滑脂皂纖維含量比較低時,壓力損失增加的速率比較慢,隨著皂纖維含量的增加,壓力損失上升的速率變快,所以皂纖維越多對壓力損失的影響越明顯。(4)隨著皂纖維的增多,每種脂所對應(yīng)的的高壓噴射狀態(tài)與低壓流動狀態(tài)壓力損失ΔP的差值逐漸減小。
[Abstract]:Through consulting a large number of documents, the subject has systematically studied the relevant theoretical knowledge of grease and built a test bed. The relationship between pressure loss and five kinds of general lithium grease with different lithium-soap fiber content was studied under the condition of high pressure injection and low pressure flow, and the influence law of grease soap fiber content on pressure loss was obtained. Grease is a very complex and changeable material, so the physical and chemical properties, structure composition, rheological properties, rheological equation and flow characteristics of lubricating grease are studied deeply in this paper. Then design the experimental schematic diagram, carry on the calibration experiment of the pressure transmitter at the same time, study the knowledge of the pipeline connection, design the pipeline connection plan, and use SOLIDWORKS to carry on the three-dimensional modeling of the pipeline connection of the experimental system. Finally, the test bench is built according to the experimental schematic diagram. In the test of lubricating grease transport characteristics, at room temperature, 00#0 #1 #1 containing different soap-fiber content, The pressure loss laws of five kinds of general lithium grease under high pressure injection state and low pressure flow state were studied, and the measured data were fitted by MATLAB curve. The curves of pressure change and pressure loss in two states are obtained. The conclusions are as follows: (1) the pressure fluctuation in high pressure injection state is larger than that in low pressure flow state, and with the increase of soap fiber, The working pressure of several kinds of lipids increases continuously under the condition of high pressure injection, and the working pressure reaches the maximum at lithium-based grease No. 3, reaching 18.7 MPA 路(2). (2) with the increase of soap fiber content, the pressure of several kinds of lipids is increased with the increase of soap-fiber content in both high pressure injection state and low pressure flow state. The pressure loss 螖 P shows an upward trend. (3) when the content of grease soap fiber is low, the increasing rate of pressure loss is slower, with the increase of soap fiber content. The pressure loss increases faster, so the more soap fiber, the more the pressure loss. (4) with the increase of soap fiber, the difference of pressure loss 螖 P between the high-pressure jet state and low-pressure flow state of each kind of fat decreases gradually.
