【摘要】：煤炭作為我國(guó)主要的一次能源,其產(chǎn)量的多少對(duì)國(guó)家的經(jīng)濟(jì)有著至關(guān)重要的作用,為了能夠加大“三下”壓煤的開(kāi)采力度以及對(duì)邊角殘煤的回收利用,使占用的耕地面積盡可能減少,最大力度的保護(hù)好生態(tài)環(huán)境,故以煤矸石為主要原料的充填采煤技術(shù)開(kāi)始飛速發(fā)展起來(lái)。膏體充填技術(shù)當(dāng)前在國(guó)內(nèi)應(yīng)用范圍很廣,其優(yōu)點(diǎn)是工作性能高、連續(xù)性強(qiáng)以及擁有穩(wěn)定的自動(dòng)控制系統(tǒng),但是,由于膏體的特殊形態(tài),對(duì)其流量的檢測(cè)還是一個(gè)難題,本文對(duì)膏體充填流量檢測(cè)進(jìn)行了研究。在膏體流動(dòng)時(shí),通過(guò)應(yīng)變片測(cè)量管壁的形變,求得管路壓力值,進(jìn)而通過(guò)壓力與流量之間的動(dòng)態(tài)關(guān)系求得膏體的瞬態(tài)流量。在理論方面,總結(jié)了管路壓力與流量的數(shù)學(xué)模型,即兩參數(shù)之間的數(shù)學(xué)關(guān)系表達(dá)式,對(duì)影響管路關(guān)系表達(dá)式的非線性因素進(jìn)行了討論,指出此方程是根據(jù)機(jī)電液之間的共性比擬得到的,與傳輸線理論中的長(zhǎng)線理論類似,故其中存在的非線性因素太多,應(yīng)對(duì)管路壓力與流量的關(guān)系表達(dá)式中各參數(shù)的設(shè)定加以改進(jìn)。在實(shí)踐方面,通過(guò)ANSYS仿真和實(shí)驗(yàn)兩方面分別進(jìn)行討論,驗(yàn)證了應(yīng)變測(cè)量系統(tǒng)的可行性,進(jìn)而將壓力值轉(zhuǎn)化求得流量,且為以后實(shí)際應(yīng)用的進(jìn)一步設(shè)計(jì)提供了基礎(chǔ)。最后,將實(shí)驗(yàn)結(jié)果和理論值進(jìn)行比較,分析誤差。
[Abstract]:As the main primary energy in our country, the output of coal plays a vital role in the national economy. In order to increase the exploitation of "three down" coal and the recovery and utilization of the residual coal in the edge corner, The area of cultivated land occupied should be reduced as much as possible and the ecological environment should be protected as much as possible. Therefore, the filling and mining technology with coal gangue as the main raw material began to develop rapidly. The paste filling technology is widely used in China at present. It has the advantages of high performance, strong continuity and stable automatic control system. However, because of the special form of paste, the detection of its flow is still a difficult problem. In this paper, the measurement of paste filling flow rate is studied. When the paste is flowing, the strain gauge is used to measure the deformation of the pipe wall, the pressure value of the pipe is obtained, and the transient flow rate of the paste is obtained by the dynamic relationship between the pressure and the flow rate. This paper summarizes the mathematical model of pipe pressure and flow rate, that is, the expression of mathematical relation between two parameters, discusses the nonlinear factors that affect the expression of pipeline relationship, and points out that the equation is obtained according to the similarity of electromechanical fluid. Similar to the long line theory in the transmission line theory, there are too many nonlinear factors, so the parameters in the expression of the relationship between pressure and flow should be improved. The feasibility of the strain measurement system is verified by ANSYS simulation and experiment, and the flow rate is obtained by transforming the pressure value into the flow rate, which provides a basis for the further design of the practical application in the future. The experimental results are compared with the theoretical values and the errors are analyzed.
