Italy ATOS Atos is our brand agent, is also one of the advantages of our brand. I Germany, the United States company. 2006 Division I and Italy ATOS Atos has successfully signed a cooperation treaty, and Italy ATOS Atos amplifiers, solenoid valves, proportional valves, piston pumps and other products of all authorized agents, our company can purchase their own customs import directly from Italy manufacturers . This ensures that the customer's product is Italy ATOS Atos products, so 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 European and American brand name products, we focus on bulk purchases to get the best discount manufacturers can offer 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.

ATOS伺服比例閥基本工作原理:atos比例閥通過(guò)電子參考信號(hào)調(diào)節(jié)液壓或動(dòng)力參數(shù)。比例閥的基本原理:相應(yīng)的參考信號(hào)產(chǎn)生對(duì)應(yīng)的電磁鐵吸力,電磁鐵吸力作用在靠彈簧復(fù)位的閥芯上,驅(qū)動(dòng)閥芯運(yùn)動(dòng),從而實(shí)現(xiàn)要求的液壓參數(shù)調(diào)節(jié)。
Atos數(shù)字式伺服比例閥可靠性高,可與優(yōu)質(zhì)的伺服閥媲美,是比例技術(shù)的*體現(xiàn),阿托斯伺服閥閥芯-閥套精密遮蓋,可閉環(huán)反饋,安全復(fù)位,高響應(yīng),數(shù)字式電子放大器出廠預(yù)設(shè),流量/壓力/位置數(shù)字控制,功能參數(shù)可通過(guò)軟件設(shè)置,對(duì)振動(dòng)和沖擊有耐震選項(xiàng),防爆&不銹鋼特殊型式可選意大利ATOS比例閥需注意的相關(guān)事項(xiàng)有能量損失, 所以使用比例閥或伺服閥的目的就是以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制(當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等)既然是節(jié)流控制。伺服閥和其它閥不同的能量損失更大一些,
因?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。只不過(guò)閥芯的換向不是靠電磁鐵來(lái)推動(dòng),滑閥結(jié)構(gòu) 伺服閥的主閥一般來(lái)說(shuō)和換向閥一樣是滑閥結(jié)構(gòu)。而是靠前置級(jí)閥輸出的液壓力來(lái)推動(dòng),這一點(diǎn)和電液換向閥比較相似,只不過(guò)電液換向閥的前置級(jí)閥是電磁換向
意大利ATOS比例閥需注意的相關(guān)事項(xiàng)而伺服閥的前置級(jí)閥是動(dòng)態(tài)特性比較好的噴嘴擋板閥或射流管閥。閥。伺服閥的主閥是靠前置級(jí)閥的輸出壓力來(lái)控制的而前置級(jí)閥的壓力則來(lái)自于伺服閥的入口p假如p口的壓力缺乏, 也就是說(shuō)。前置級(jí)閥就不能輸出足夠的壓力來(lái)推動(dòng)主閥芯動(dòng)作。 而我知道,當(dāng)負(fù)載為零的時(shí),如果四通滑閥*打開(kāi),候。p口壓力=t口壓力+閥口壓力損失(忽略油路上的其它壓力損失)如果閥口壓力損失很小,t口壓力又為零,那么p口的壓力就缺乏以供給前置級(jí)閥來(lái)推動(dòng)主閥芯,整個(gè)伺服閥就失效了。
意大利ATOS比例閥需注意的相關(guān)事項(xiàng)即使在閥口全開(kāi)的情況下,所以伺服閥的閥口做得偏小。也要有一定的壓力損失,來(lái)維持前置級(jí)閥的正常工作。
意大利ATOS比例閥需注意的相關(guān)事項(xiàng)好處只有一個(gè):動(dòng)態(tài)性能是所有液壓閥中zui高的就憑著這一個(gè)優(yōu)點(diǎn), 伺服閥其實(shí)缺點(diǎn)極多:能耗浪費(fèi)大、容易出故障、抗污染能力差、價(jià)格高貴等等等等。很多對(duì)動(dòng)態(tài)特性要求高的場(chǎng)所不得不使用伺服閥,如飛機(jī)火箭的舵機(jī)控制、汽輪機(jī)調(diào)速等等。動(dòng)態(tài)要求低一點(diǎn)的基本上都是比例閥的天下了
一般說(shuō)來(lái),好像伺服系統(tǒng)都是閉環(huán)控制。比例多用于開(kāi)環(huán)控制;其次比例閥類型要多,有比例壓力、流量控制閥等,控制比伺服要靈活一些。從他內(nèi)部結(jié)構(gòu)看,伺服閥多是零遮蓋,比例閥則有一定的死區(qū)。
