影響德FESTO電磁閥技術(shù)發(fā)展的因素主要資料有哪些
德FESTO電磁閥作為自動(dòng)化儀表的一種執(zhí)行器,近年來用量急劇上升。本文分析了德FESTO電磁閥的主要特點(diǎn),并側(cè)重應(yīng)用的角度對(duì)內(nèi)成熟技術(shù)的發(fā)展動(dòng)態(tài) 作簡要綜述,分別在精簡化、智能化、通用化、化方向作了考察,并略對(duì)影響電磁閥技術(shù)發(fā)展的社會(huì)因素作點(diǎn)探討。 (1)外漏堵,內(nèi)漏易控,安全。 內(nèi)外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出,由電動(dòng)、氣動(dòng)、液動(dòng)執(zhí)行機(jī)構(gòu)控制閥芯的轉(zhuǎn)動(dòng)或移動(dòng)。這都要解決長期動(dòng)作 閥桿動(dòng)密封的外泄漏難題;唯有電磁閥是用電磁力作用于密封在隔磁套管內(nèi)的鐵芯完成,不存在動(dòng)密封,所以外漏易堵。電動(dòng)閥力矩控制 不易,容易產(chǎn)生內(nèi)漏,甚拉斷閥桿頭部;德FESTO電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏,直降為零。所以,德FESTO電磁閥特別安全,尤其適用于腐蝕 性、有毒或高低溫的介質(zhì)。 (2)系統(tǒng)簡單,便接電腦,低謙。 電磁閥本身結(jié)構(gòu)簡單,也低,比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。更顯著的是所組成的自控系統(tǒng)簡單得多,要低得多 。由于德FESTO電磁閥是開關(guān)信號(hào)控制,與工控計(jì)算機(jī)連接十分方便。在電腦普及,大幅下降的時(shí)代,德FESTO電磁閥的就更加明顯。 (3)動(dòng)作快遞,功率微小,外形輕巧。 電磁閥響應(yīng)時(shí)間可以短幾個(gè)毫秒,即使是導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。由于自成回路,比之其它自控閥反應(yīng)更靈敏。設(shè)計(jì) 得當(dāng)?shù)碾姶砰y線圈功率消耗很低,屬節(jié)能產(chǎn)品;還可做到只需觸發(fā)動(dòng)作,自動(dòng)保持閥位,平時(shí)一點(diǎn)也不耗電。德FESTO電磁閥外形尺寸小,既節(jié)省空 間,又輕巧美觀。
譯文:
Solenoid valve as an actuator automation, in recent years, consumption rose sharply. This paper analyzes the main characteristics of the electromagnetic valve, dynamic development and focus on the application point of view to the domestic mature technologies are summarized, respectively, in the streamlined, inligent, universal, made a special study of the direction, and a little on the social factors that influence the development of solenoid valve technology point to explore. (1) leakage blocking must, easy to control leakage, the use of safety. Internal and external leakage is endangering the safety factor. Other automatic control valve will usually stem out from the electric, pneumatic, hydraulic actuator control valve, rotate or move. This should solve the long-term action of external dynamic seal valve stem leakage problem; only the electromagnetic solenoid valve is the use of electromagnetic force to complete sealed compartment inside the magnetic core casing, there is no dynamic seal, so easy to block leakage. Electric torque control valve is not easy, prone to internal leakage, and even pull off the stem head; structure of the solenoid valve is easy to control leakage, until reduced to zero. Therefore, the use of special safety valve, especially for corrosive, toxic or high temperature media. (2) the system is simple, they take the computer, low price and modest. Solenoid valve itself is simple, the price is low, compared to other types of valve actuator is easy to install and maintain. More significant is the automatic control system consisting of much simpler, much lower price. As the solenoid valve is a switch signal control, and industrial computer connection is very convenient. Popular in today's computer, the era of decline in prices, the electromagnetic valve is even more obvious advantages.
