【摘要】：徑向柱塞泵由于具有結(jié)構(gòu)緊湊,高壓、大流量等一系列優(yōu)點,使得近年來逐步得到發(fā)展,被廣泛應(yīng)用于各行各業(yè)。軸配流式徑向柱塞泵因轉(zhuǎn)子與配流軸的偏磨和“抱軸”現(xiàn)象嚴(yán)重以及配流軸的加工精度要求比較高,目前國內(nèi)生產(chǎn)的大多工作于25MPa以下,無法適應(yīng)于高壓和超高壓液壓系統(tǒng)。而閥配流式徑向柱塞泵采用偏心軸轉(zhuǎn)動帶動柱塞往復(fù),利用單向閥實現(xiàn)配流,其優(yōu)點主要在于結(jié)構(gòu)簡單,易于制造,而且工作壓力高,一般可以達(dá)到20～40MPa,它是各類液壓泵中工作壓力最高的一種。 4JB徑向往復(fù)式柱塞泵采用單拐雙滑機構(gòu),具有體積小,結(jié)構(gòu)簡單,可以實現(xiàn)高壓輸出等優(yōu)勢。目前已經(jīng)研發(fā)并制造了一個型號,但是針對廣闊的市場,一個型號是遠(yuǎn)遠(yuǎn)不夠的。而且從目前市場上的泵類產(chǎn)品看來,幾乎所有的廠家都開發(fā)了產(chǎn)品的相應(yīng)系列。為了快速開拓市場,實現(xiàn)泵產(chǎn)品的產(chǎn)業(yè)化和規(guī)�；�,我們對柱塞泵的設(shè)計進(jìn)行了參數(shù)化,目的是縮短產(chǎn)品設(shè)計周期,減少開發(fā)資本。經(jīng)過參數(shù)化設(shè)計,柱塞泵流量范圍為2.5～100m3/h,工作壓力10～100MPa。在柱塞泵的參數(shù)化過程中,關(guān)鍵部分是如何實現(xiàn)柱塞泵結(jié)構(gòu)參數(shù)與泵的實際流量與工作壓力這兩個參數(shù)之間的聯(lián)動關(guān)系。本文主要內(nèi)容總結(jié)如下： 1.分析柱塞泵主要參數(shù)的變化并找出與其與柱塞泵總體結(jié)構(gòu)參數(shù)之間的約束關(guān)系。找出各個零部件主要參數(shù)以及他們之間的裝配關(guān)系�？傮w參數(shù)工作壓力P與實際流量Q決定電機類型和軸承型號的選擇。因此,文中建立了P、Q與電機額定功率以及軸承基本額定動載荷之間的約束關(guān)系。針對參數(shù)化系統(tǒng)而言,要實現(xiàn)電機與軸承的參數(shù)化選擇,本文利用VB. NET與SQL Server建立了電機與軸承參數(shù)的數(shù)據(jù)庫,可以隨時調(diào)出所需參數(shù)。 2.研究主軸系統(tǒng)動平衡內(nèi)容,分析動不平衡的原因以及影響動平衡的參數(shù),并建立主軸系統(tǒng)動平衡參數(shù)方程,結(jié)合VB. NET軟件的計算功能對主軸動平衡和強度進(jìn)行計算和驗算。 3.建立徑向柱塞泵主要零部件參數(shù)之間的聯(lián)動關(guān)系,如柱塞、平動滑塊、滑板、吸入排出閥等,結(jié)合Pro/E軟件自身的參數(shù)化功能以及它的VB API函數(shù)功能,利用VB. NET軟件對零部件進(jìn)行參數(shù)化建模。最后就是建立徑向柱塞泵的參數(shù)化系統(tǒng),實現(xiàn)參數(shù)化功能。
[Abstract]:Radial piston pump has been developed gradually in recent years because of its compact structure, high pressure, large flow rate and so on, and has been widely used in various industries. Radial piston pump with axial distribution flow is not suitable for high pressure and ultra high pressure hydraulic system because of the serious phenomenon of eccentric wear and "holding shaft" of rotor and flow distribution shaft and the high precision requirement of flow distribution shaft processing. At present, most of the domestic production works below 25MPa and can not be adapted to high pressure and super high pressure hydraulic system. The radial piston pump with valve distribution adopts eccentric shaft rotation to drive piston reciprocating and unidirectional valve to realize flow distribution. Its advantages lie in its simple structure, easy manufacture, and high working pressure. It is the highest working pressure in all kinds of hydraulic pumps. The radial reciprocating piston pump of 4JB has the advantages of small volume, simple structure and high pressure output. A model has been developed and manufactured, but for the vast market, one model is far from enough. And from the current market pump products, almost all manufacturers have developed the corresponding series of products. In order to develop the market quickly and realize the industrialization and scale of pump products, the design of plunger pump is parameterized in order to shorten the period of product design and reduce the development capital. After parameterized design, the flow range of piston pump is 2.5 渭 m ~ (3 / h) and the working pressure is 10 ~ (10) m ~ (3 / h). In the process of piston pump parameterization, the key part is how to realize the linkage between the structure parameters of piston pump and the actual flow rate and working pressure of the pump. The main contents of this paper are summarized as follows: 1. The change of main parameters of piston pump is analyzed and the constraint relation between it and the total structure parameter of piston pump is found out. Find out the main parameters of each component and the assembly relationship between them. The working pressure P and actual flow Q determine the choice of motor type and bearing type. Therefore, the constraint relationship between PQ, rated power of motor and basic dynamic load of bearing is established in this paper. In view of the parameterized system, to realize the parameterized selection of motor and bearing, this paper uses VB. NET and SQL Server have established the database of motor and bearing parameters, and can call out the required parameters at any time. 2. The contents of dynamic balance of spindle system are studied, the cause of dynamic unbalance and the parameters affecting dynamic balance are analyzed, and the equation of dynamic balance parameter of spindle system is established. The calculation function of NET software is to calculate and check the dynamic balance and strength of spindle. 3. The linkage relationship between the parameters of the main parts of the radial piston pump is established, such as plunger, sliding slider, slide plate, suction discharge valve, etc. Combined with the parameterized function of Pro/E software and the function of VB API function, the function of VB API is used. The parametric modeling of parts is carried out by NET software. Finally, the parametric system of radial piston pump is established to realize parameterization function.
