【摘要】：長(zhǎng)期以來(lái),煤礦綜采工作面的粉塵危害一直是困擾著煤礦安全生產(chǎn)的一大難題。隨著科技的迅猛發(fā)展,人類社會(huì)物質(zhì)生活水平的提高,人們對(duì)各類職業(yè)病的關(guān)注程度越來(lái)越高,尤其是工作環(huán)境十分惡劣的煤礦井下作業(yè)的關(guān)注更為突出,各大煤炭開采國(guó)均相繼提出日益要求更高的對(duì)工人身心健康有利的相關(guān)標(biāo)準(zhǔn),故開發(fā)和研制高效井下除塵降塵設(shè)備的需求越來(lái)越迫切。眾所周知,礦用噴霧泵通過將電動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換為工作介質(zhì)(水)的液壓能,使之霧化來(lái)實(shí)現(xiàn)為采煤機(jī)、掘進(jìn)機(jī)等采掘設(shè)備工作場(chǎng)地除塵降塵的目的。通過市場(chǎng)調(diào)研得知：合理的結(jié)構(gòu)設(shè)計(jì)和參數(shù)選擇不僅是噴霧泵正常工作的保證,更是延長(zhǎng)產(chǎn)品使用壽命的重要因素。因此,新型高壓噴霧泵的開發(fā)研制具有極其重要的理論意義和應(yīng)用價(jià)值。課題以BPW100／16型噴霧泵為實(shí)例,所做的主要工作如下： 1.基于噴霧泵的工作原理和使用工況特點(diǎn)的分析與研究,提出了“大行程,小直徑”的設(shè)計(jì)理念,確定出噴霧泵的原始數(shù)據(jù),推導(dǎo)出相關(guān)參數(shù)的計(jì)算方法； 2.通過對(duì)噴霧泵總體結(jié)構(gòu)的解析,提出了噴霧泵的壓力控制系統(tǒng)特點(diǎn),給出了其核心部件中的缸套組件和閥體組件的整體結(jié)構(gòu)設(shè)計(jì)、材料選擇及加工工藝措施,得出了一種解決閥體滯后問題的新型閥體設(shè)計(jì)方法,有效地提高了噴霧泵的容積效率； 3.基于運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)的基本原理和理論,采用解析法揭示了曲柄連桿組件的運(yùn)動(dòng)規(guī)律及原理,建立了其運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)數(shù)學(xué)模型,歸納出該部件設(shè)計(jì)要求、原則和方法,探索出相應(yīng)的選材及加工工藝措施； 4.基于新建立的動(dòng)力學(xué)和運(yùn)動(dòng)學(xué)數(shù)學(xué)模型,利用相關(guān)強(qiáng)度校核理論和方法,采用現(xiàn)代設(shè)計(jì)和仿真軟件,通過對(duì)本研究對(duì)象的關(guān)鍵核心部件的仿真和驗(yàn)證,結(jié)果表明：該模型合理可行,滿足設(shè)計(jì)要求。
[Abstract]:For a long time, dust hazard in fully mechanized coal mining face has been a big problem puzzling coal mine safety production. With the rapid development of science and technology and the improvement of material living standard of human society, people pay more and more attention to all kinds of occupational diseases. In particular, the concern of underground operations in coal mines, where the working environment is very bad, is even more prominent. All the major coal mining countries have successively put forward relevant standards which are increasingly demanding higher standards that are beneficial to the physical and mental health of workers. Therefore, it is more and more urgent to develop and develop high efficiency downhole dust and dust control equipment. As is known to all, the spray pump for mining is realized as a shearer by converting the mechanical energy of the motor into the hydraulic energy of the working medium (water) and making it atomized. Through market research, we know that reasonable structure design and parameter selection are not only the guarantee of the normal operation of the spray pump, but also the important factor to prolong the service life of the product. The research and development of a new type of high pressure spray pump is of great theoretical significance and application value. Taking BPW100/16 type spray pump as an example, the main work done is as follows:. 1. Based on the analysis and research of the working principle and operating conditions of the spray pump, the design concept of "large stroke and small diameter" is put forward, the original data of the spray pump is determined, and the calculation method of related parameters is deduced. 2. Through the analysis of the overall structure of the spray pump, the characteristics of the pressure control system of the spray pump are put forward, and the integral structure design, material selection and processing technology of the cylinder liner assembly and valve body assembly in the core parts of the spray pump are given. A new design method of valve body is obtained, which can effectively improve the volumetric efficiency of spray pump. 3. Based on the basic principles and theories of kinematics and dynamics, the movement law and principle of crank and connecting rod assembly are revealed by analytic method, the mathematical model of kinematics and dynamics is established, and the design requirements, principles and methods of the component are summarized. Explore the corresponding material selection and processing technology measures; 4. Based on the newly established mathematical model of dynamics and kinematics, using the theory and method of correlation strength checking, using modern design and simulation software, the key components of this research object are simulated and verified. The results show that the model is reasonable and feasible and meets the design requirements.
