【摘要】：液壓控制回路有雙負載腔聯(lián)動式控制、單負載腔聯(lián)動式控制和單負載腔獨立式控制三種方式。單負載腔獨立式控制回路遵循了一個基本的組合原則：最少液阻原則�？梢愿爬椋涸诓捎猛ㄟ^調(diào)整液流阻力進行流量控制的“控制液壓傳動”中,全部可控執(zhí)行器的“受控腔”控制回路都可以通過最少或較少的液阻來加以組成。這應當成為評價液壓控制回路和系統(tǒng)設(shè)計合理性的基本原則之一。單負載腔獨立式控制回路的基本控制元件是二通插裝閥。 由于比例控制技術(shù)、伺服控制技術(shù)及數(shù)字控制技術(shù)等與二通插裝技術(shù)相結(jié)合,二通插裝閥的性能得到了很大的提高,但現(xiàn)有市售的國內(nèi)外二通插裝閥產(chǎn)品,安裝孔符合IS07368標準,主要應用于大中功率或稱為高壓大流量的液壓傳動與控制中。實際上,二通插裝閥還具有在中小功率液壓控制中被大量應用,尤其是在采用集成化連接時被大量采用的很大潛力和空間。其技術(shù)關(guān)鍵在于急需對現(xiàn)有的二通插裝閥市售產(chǎn)品進行規(guī)模性和整體性的重組和結(jié)構(gòu)創(chuàng)新。為此,上海人豪液壓集成開發(fā)室總設(shè)計師黃人豪先生提出了MINISO型二通插裝閥,包括小型化和小規(guī)格的先導控制閥、組合式法蘭控制蓋板、小型化主級及其模塊化組合等主要內(nèi)容。 通過學習MINISO標準,論文設(shè)計了16通徑的MINISO型位移—力反饋比例節(jié)流閥、MINISO型位移—力反饋單向比例節(jié)流閥和MINISO型間接檢測式比例壓力閥。文中分析了每個MINISO閥的基本結(jié)構(gòu)、工作原理和設(shè)計計算；其后,建立每個MINISO閥的數(shù)學模型,利用專業(yè)的液壓仿真軟件AMESim對設(shè)計參數(shù)進行優(yōu)化；優(yōu)化后,使用SolidWorks軟件設(shè)計MINISO閥的三維視圖,使用AutoCAD軟件繪制零件圖和裝配圖,然后制定工藝并送廠加工；加工和裝配完成后,對MINISO型比例節(jié)流閥和比例壓力閥進行了性能測試試驗,包括動態(tài)和靜態(tài)試驗,驗證了MINISO標準的可行性。 最后設(shè)計了基于MINISO標準的四通集成塊,與兩個單向比例節(jié)流閥和兩個比例壓力閥構(gòu)成可獨立調(diào)節(jié)的四通電液比例插裝集成單元,對挖掘機動臂油缸進行單負載腔的獨立式控制,實現(xiàn)了在主泵卸荷卸流的情況下,動臂下降過程中的負負載流量再生。
[Abstract]:There are three types of hydraulic control loop: dual load cavity linkage control, single load cavity linkage control and single load cavity independent control.The single-load cavity independent control loop follows a basic combination principle: the principle of minimum liquid resistance.It can be concluded that in the "controlled hydraulic transmission" which is controlled by adjusting the flow resistance, the "controlled cavity" control loop of all controllable actuators can be made up of the least or less liquid resistance.This should be one of the basic principles for evaluating the rationality of hydraulic control circuit and system design.The basic control element of single-load cavity independent control loop is two-way cartridge valve.Because of the combination of proportional control technology, servo control technology and digital control technology, the performance of two-way cartridge valve has been greatly improved. However, the installation hole of domestic and foreign two-way cartridge valve products is in line with IS07368 standard.Mainly used in large and medium power or called high pressure and large flow hydraulic transmission and control.In fact, the two-way cartridge valve also has the great potential and space to be widely used in medium and small power hydraulic control, especially in the use of integrated connection.The technical key lies in the urgent need to restructure and innovate the existing two-way cartridge valve market products on a scale and integrity basis.For this reason, Mr. Huang Renhao, chief designer of Shanghai Renhao hydraulic Integrated Development Room, has proposed MINISO two-way cartridge valves, including miniaturized and small-size pilot control valves, combined flange control covers,Miniaturization of the principal stage and its modular combination and other main contents.By studying the MINISO standard, the paper designs MINISO displacement force feedback proportional throttle valve with 16 diameter and MINISO indirect detection proportional pressure valve with displacement-force feedback one-way proportional throttle valve.In this paper, the basic structure, working principle and design calculation of each MINISO valve are analyzed. Then, the mathematical model of each MINISO valve is established, and the design parameters are optimized by using the professional hydraulic simulation software AMESim.Using SolidWorks software to design 3D view of MINISO valve, using AutoCAD software to draw part drawing and assembly drawing, and then working out the process and sending it to the factory for processing. After processing and assembling, the performance tests of MINISO proportional throttle valve and proportional pressure valve are carried out.The feasibility of MINISO standard is verified by both dynamic and static tests.Finally, a four-way integrated block based on MINISO standard is designed, which is composed of two unidirectional proportional throttle valves and two proportional pressure valves. The four-way electro-hydraulic proportional interpolation and integration unit can be adjusted independently, and the single load cavity of the excavator arm oil cylinder is controlled independently.Under the condition of the main pump unloading and unloading, the negative carrier flow regeneration is realized during the falling of the arm.
