United States MOOG Moog is our brand agent, is also one of the advantages of our brand. 2006 Division I with the United States MOOG Moog has successfully signed a cooperation treaty, and authorized agent for all products US Moog MOOG servo valve, domestic customers in each place, and some exports. Our company can purchase directly from the manufacturers own declaration of imports. This ensures that the customer's product is imported from Germany Rexroth products, so that customers can avoid domestic agents, offices and distributors grading agency, layers of exploitation patterns, enjoy low prices and short delivery time European original authentic 100% procurement services. For some well-known German brand products, we focus on bulk purchasing discounts to get the best vendor that can provide lower than the domestic market price quotations. For less easy to find the small German and European brand of industrial products, we can help you find and purchase on behalf of, the Company's direct supplier of European SMEs has reached more than 1,000.

MOOG穆格伺服閥細(xì)致材料:
典型電---氣比例閥、伺服閥的工作原理 電---氣比例閥和伺服閥按其功用可分為壓力式和流量式兩種。壓力式比例/伺服閥將輸給的電信號(hào)線性地轉(zhuǎn)換為氣體壓力;流量式比例/伺服閥將輸給的電信號(hào)轉(zhuǎn)換為氣體流量。美國(guó)威格士VICKERS柱塞泵由于氣體的可緊縮性,使氣缸或氣馬達(dá)等執(zhí)行元件的運(yùn)動(dòng)速度不只取決于氣體流量。還取決于執(zhí)行元件的負(fù)載大小。因而準(zhǔn)確地控制氣體流量常常是不用要的。美國(guó)穆格MOOG伺服閥單純的壓力式或流量式比例/伺服閥應(yīng)用不多,常常是壓力和流量分離在一同應(yīng)用更為普遍。 電---氣比例閥和伺服閥主要由電---機(jī)械轉(zhuǎn)換器和氣動(dòng)放大器組成。但隨著近年來(lái)低價(jià)的電子集成電路和各種檢測(cè)器件的大量呈現(xiàn),在1電---氣比例/伺服閥中越來(lái)越多地采用了電反應(yīng)辦法,這也大大進(jìn)步了比例/伺服閥的性能。電---氣比例/伺服閥可采用的反應(yīng)控制方式,閥內(nèi)就增加了位移或壓力檢測(cè)器件,有的還集成有控制放大器。 滑閥式電---氣方向比例閥 美國(guó)穆格伺服閥,流量式四通或五通比例控制閥能夠控制氣動(dòng)執(zhí)行元件在兩個(gè)方向上的運(yùn)動(dòng)速度,這類(lèi)閥也稱(chēng)方向比例閥。圖示即為這類(lèi)閥的構(gòu)造原理圖。它由直流比例電磁鐵1、閥芯2、閥套3、閥體4、位移傳感器5和控制放大器6等同意。位移傳感器采用電感式原理,它的作用是將比例電磁鐵的銜鐵位移線性地轉(zhuǎn)換為電壓信號(hào)輸出??刂品糯笃鞯闹饕饔檬牵?1)將位移傳感器的輸出信號(hào)停止放大; 2) 比擬指3)令信號(hào)Ue和位移反應(yīng)信號(hào)Uf,4)得到兩者的差植5)U; 6) 將 U放大,7) 轉(zhuǎn)換為電流信號(hào)I輸出。此外,8) 為了改善比例閥的性能,9)控制放大器還含有對(duì)反應(yīng)信號(hào)Uf和電壓差 U的處置環(huán)節(jié)。比方狀態(tài)反應(yīng)控制和PID調(diào)理等。帶位置反應(yīng)的滑閥式方向比例閥,其工作原理是:在初始狀態(tài),控制放大器的指令信號(hào)UF=0,閥芯處于零位,此時(shí)氣源口P與A、B兩端輸出口同時(shí)被切斷,A、B兩口與排氣口也切斷,無(wú)流量輸出;同時(shí)位移傳感器的反應(yīng)電壓Uf=0。若閥芯遭到某種干擾而偏離調(diào)定的零位時(shí),美國(guó)穆格MOOG伺服閥位移傳感器將輸出一定的電壓Uf,控制放大器將得到的 U=-Uf放大后輸出給電流比例電磁鐵,電磁鐵產(chǎn)生的推力迫使閥芯回到零位。若指令Ue>0,則電壓差U增大,使控制放大器的輸出電流增大,比例電磁鐵的輸出推力也增大,推進(jìn)閥芯右移。而閥芯的右移又惹起反應(yīng)電壓Uf的增大,直至Uf與指令電壓Ue根本相等,閥芯到達(dá)力均衡。此時(shí):Ue=Uf=KfX(Kf為位移傳感器增益)
