RD-11阻旋式料位開(kāi)關(guān)產(chǎn)品介紹(中文)
RD-11阻旋式料位開(kāi)關(guān)是一種用于固態(tài)物料(如粉狀、粒狀、塊狀)的物位監(jiān)測(cè)設(shè)備。其核心原理是通過(guò)微型馬達(dá)驅(qū)動(dòng)葉片旋轉(zhuǎn),當(dāng)物料接觸葉片時(shí),馬達(dá)停止運(yùn)轉(zhuǎn)并輸出開(kāi)關(guān)信號(hào),實(shí)現(xiàn)料位報(bào)警或控制。該設(shè)備采用雙層防塵密封設(shè)計(jì)和特殊油封技術(shù),能有效防止粉塵滲入,適用于水泥、煤炭、化工等高粉塵環(huán)境。葉片扭力可根據(jù)物料比重靈活調(diào)節(jié),并具備過(guò)載保護(hù)功能,當(dāng)葉片承受過(guò)大阻力時(shí),離合器自動(dòng)打滑以保護(hù)電機(jī)。產(chǎn)品支持水平或垂直安裝,法蘭連接規(guī)格可定制,適應(yīng)不同工況需求。
RD-11的葉片材質(zhì)為不銹鋼,耐腐蝕且耐磨,適用于-20℃至80℃的環(huán)境溫度(高溫型號(hào)可擴(kuò)展至200℃)。其結(jié)構(gòu)簡(jiǎn)單,維護(hù)便捷,廣泛應(yīng)用于冶金、飼料、食品加工等行業(yè),特別適合料倉(cāng)、灰?guī)斓葓?chǎng)景的料位監(jiān)測(cè)。設(shè)備功耗低(3W),支持AC220V或DC24V供電,輸出接點(diǎn)容量為5A/250VAC,防護(hù)等級(jí)達(dá)IP65,確保在惡劣條件下穩(wěn)定運(yùn)行。
RD-11 Rotary Paddle Level Switch (English Introduction)
The RD-11 rotary paddle level switch is designed for monitoring solid materials such as powders, granules, and bulk solids. It operates by rotating a paddle via a micro motor; when material obstructs the paddle, the motor stops and triggers a switch signal for level control. Featuring a dual-layer dust-proof seal and specialized oil sealing, it effectively resists dust ingress, making it suitable for high-dust environments like cement silos, coal bunkers, and chemical plants.
The paddle torque is adjustable to accommodate materials of varying densities, and an overload protection mechanism disengages the clutch to safeguard the motor if excessive resistance occurs. The switch supports both horizontal and vertical installation, with customizable flange connections for flexible application. Constructed with stainless steel paddles, it offers corrosion resistance and durability within a temperature range of -20℃ to 80℃ (extendable to 200℃ for high-temperature models).
With low power consumption (3W) and compatibility with AC220V/DC24V power supply, the RD-11 provides reliable performance in industries such as metallurgy, feed processing, and food production. Its SPDT output (5A/250VAC) and IP65 protection ensure stable operation under harsh conditions. The simple mechanical structure minimizes maintenance needs, ideal for continuous monitoring in hoppers, bins, and similar storage systems.

一、產(chǎn)品簡(jiǎn)介:
阻旋開(kāi)關(guān)是用于固態(tài)物料(包括粉狀、塊狀、粒狀、膠狀等)的物位控制器。它具有密封性好、過(guò)載能力強(qiáng)、輕便易裝、輸出觸點(diǎn)容量大等特點(diǎn)。針對(duì)不同比重的物料可通過(guò)調(diào)彈簧的拉力來(lái)實(shí)現(xiàn),其接觸物料部分全為不銹鋼材料。阻旋開(kāi)關(guān)在化工、塑料、水泥、制藥、飼料、食品等行業(yè)得到了廣泛的應(yīng)用。
二、工作原理
電機(jī)帶動(dòng)葉片旋轉(zhuǎn),當(dāng)被側(cè)介質(zhì)到達(dá)葉片位置時(shí),葉片手足停止轉(zhuǎn)動(dòng),從而觸動(dòng)后面的微動(dòng)開(kāi)關(guān)輸出開(kāi)關(guān)信號(hào),當(dāng)被測(cè)介質(zhì)下降離開(kāi)葉片時(shí),葉片在彈簧的作用下恢復(fù)原位繼續(xù)轉(zhuǎn)動(dòng)。彈簧的拉力可根據(jù)所測(cè)介質(zhì)的比重進(jìn)行調(diào)整,物料比重大時(shí)彈簧調(diào)整到*強(qiáng),反之調(diào)至*弱。
