【摘要】：乳化液泵是為綜采工作面的液壓支架等提供動力的主要設(shè)備,由于乳化液泵主要用于綜采工作面,其工作環(huán)境惡劣,灰塵、礦灰多,而且承受的外界負(fù)載大,需要連續(xù)不斷的運行。所以,對乳化液泵的安全性、可靠性、穩(wěn)定性等指標(biāo)就非常嚴(yán)格。S375乳化液泵由英國RMI雷波泵站公司生產(chǎn)的,其結(jié)構(gòu)簡單、穩(wěn)定、可靠、面維修等特點是國產(chǎn)乳化液泵無法達到的。為此,無論從實用性還是從科學(xué)性出發(fā),開展對S375乳化液泵的研究工作,保障綜采工作高效、安全、有序的進行是具有重要意義的,根據(jù)往復(fù)泵的設(shè)計標(biāo)準(zhǔn),對S375乳化液泵結(jié)構(gòu)及特性進行分析、設(shè)計和研制。本論文首先對S375乳化液泵的基本結(jié)構(gòu)及其重要部件進行分析,通過它的實際工作情況分析了各部分結(jié)構(gòu)的工作原理,并對乳化液泵的結(jié)構(gòu)參數(shù)進行分析計算,以此確定它的基本結(jié)構(gòu)參數(shù)。接下來對S375乳化液泵的運動進行分析,推導(dǎo)出數(shù)學(xué)建模,通過Matlab軟件進行仿真,從而得到柱塞的運動規(guī)律。同時對乳化液泵的流量在不同滯后角條件下進行分析,推導(dǎo)出數(shù)學(xué)建模,并進行仿真分析,得到泵瞬時流量在不同滯后角下的脈動規(guī)律。經(jīng)對比分析得出泵運動對流量脈動所造成影響。流量脈動必然對系統(tǒng)產(chǎn)生壓力脈動,而壓力脈動會對系統(tǒng)產(chǎn)生壓力沖擊,故進一步對泵的系統(tǒng)進行分析,建立起系統(tǒng)的模型,通過AMEsim軟件對泵系統(tǒng)進行仿真分析,得到其壓力沖擊規(guī)律,通過與實際結(jié)論比對可知泵的基本性能參數(shù)符合要求。最后,對泵的兩個重要部件曲軸、連桿分別進行靜態(tài)分析和動態(tài)分析,通過有限元的仿真分析可以得出兩個部件的結(jié)構(gòu)設(shè)計合理,從而驗證兩個重要部件的結(jié)構(gòu)參數(shù)設(shè)計符合理論要求。本論文對S375乳化液泵的參數(shù)及性能分析,是為了進一步設(shè)計、優(yōu)化、研制S375乳化液泵提供一定的理論基礎(chǔ)。
[Abstract]:Emulsion pump is the main equipment to provide power for hydraulic support in fully mechanized coal mining face. Because the emulsion pump is mainly used in fully mechanized mining face, its working environment is bad, dust and coal ash are much, and the external load is large. Therefore, the safety, reliability and stability of the emulsion pump are very strict. The S375 emulsion pump is produced by the UK RMI Leibo pumping Station Company. Its structure is simple, stable and reliable. Surface maintenance and other characteristics are beyond the reach of domestic emulsion pumps. Therefore, it is of great significance to carry out the research on S375 emulsion pumps from both practical and scientific aspects to ensure the efficient, safe and orderly operation of fully mechanized coal mining. According to the design standard of reciprocating pump, the structure and characteristics of S375 emulsion pump are analyzed, designed and developed. The working principle of each part of the pump is analyzed through its actual working conditions, and the structural parameters of the emulsion pump are analyzed and calculated to determine its basic structural parameters. Then, the movement of the S375 emulsion pump is analyzed. The mathematical modeling is deduced and simulated by Matlab software, and the movement law of plunger is obtained. At the same time, the flow rate of emulsion pump is analyzed under different lag angles, and the mathematical model is deduced, and the simulation analysis is carried out. The effect of pump motion on flow pulsation is obtained by comparison and analysis. Flow pulsation will inevitably produce pressure pulsation on the system, and pressure pulsation will produce pressure shock on the system. Therefore, the pump system is further analyzed, the system model is established, the pump system is simulated and analyzed by AMEsim software, the pressure impact law is obtained, and the basic performance parameters of the pump are compared with the actual results. Finally, the basic performance parameters of the pump meet the requirements. The static analysis and dynamic analysis of the two important parts of the pump crankshaft and connecting rod are carried out respectively. The structural design of the two components is reasonable through the simulation analysis of the finite element method. In this paper, the analysis of the parameters and performance of S375 emulsion pump is to provide a theoretical basis for further design, optimization and development of S375 emulsion pump.
