PRL-200阻旋式料位開(kāi)關(guān)產(chǎn)品介紹（中英文）
PRL-200阻旋式料位開(kāi)關(guān)是一種依據(jù)被測(cè)物料密度設(shè)計(jì)的接觸型料位檢測(cè)裝置，適用于粉粒狀、塊狀物料的料位監(jiān)測(cè)。該產(chǎn)品采用永磁電機(jī)驅(qū)動(dòng)葉片旋轉(zhuǎn)（轉(zhuǎn)速5-6轉(zhuǎn)/分），當(dāng)物料上升阻礙葉片轉(zhuǎn)動(dòng)時(shí)，機(jī)械傳動(dòng)機(jī)構(gòu)會(huì)觸發(fā)開(kāi)關(guān)信號(hào)并自動(dòng)切斷電源。其耐熱性能支持罐內(nèi)最高200℃的工作環(huán)境（PRL-200S型號(hào)可達(dá)400℃），軸保護(hù)管設(shè)計(jì)增強(qiáng)密封性，料桿標(biāo)準(zhǔn)長(zhǎng)度150mm并支持定制加長(zhǎng)。產(chǎn)品通過(guò)鋁合金鑄造殼體與靜電噴塑工藝實(shí)現(xiàn)耐沖擊和防腐蝕，葉片過(guò)載時(shí)會(huì)自動(dòng)打滑保護(hù)電機(jī)，維護(hù)時(shí)無(wú)需整體拆卸料倉(cāng)。典型應(yīng)用包括電力、水泥行業(yè)的原煤倉(cāng)、生料倉(cāng)等場(chǎng)景，安裝時(shí)需避開(kāi)進(jìn)料口并調(diào)整彈簧扭力以適應(yīng)不同物料密度。135
The PRL-200 Rotary Paddle Level Switch is a mechanical point level detector designed for bulk solids like powders and granules. Its rotating paddle (1 RPM) gets obstructed by rising material, triggering a microswitch signal through spring-loaded displacement mechanism. The heat-resistant version withstands up to 200°C process temperature (400°C for PRL-200S) with optional air cooling accessories. Standard 150mm probe length can be customized in 100mm increments, while the triple-sealed shaft prevents dust ingress. The aluminum alloy housing with anti-corrosion coating ensures durability in harsh environments like coal plants and cement silos. Featuring overload slip clutch protection and top/side mounting options, it requires no sensitivity adjustment and maintains stable performance even with material property variations. Installation recommendations include avoiding direct material flow impact and selecting appropriate blade size for lightweight substances.51214
產(chǎn)品特點(diǎn)與工作原理
該設(shè)備通過(guò)純機(jī)械結(jié)構(gòu)實(shí)現(xiàn)料位檢測(cè)，無(wú)需電子調(diào)試即可投入運(yùn)行。微電機(jī)經(jīng)減速后帶動(dòng)檢測(cè)葉片低速旋轉(zhuǎn)，物料阻擋葉片時(shí)會(huì)使主軸產(chǎn)生旋轉(zhuǎn)位移，先觸發(fā)料位信號(hào)微動(dòng)開(kāi)關(guān)，隨后切斷電機(jī)電源；當(dāng)料位下降后，彈簧機(jī)構(gòu)自動(dòng)復(fù)位并恢復(fù)電機(jī)運(yùn)轉(zhuǎn)。獨(dú)特的三重軸密封和整塊鋁合金散熱片設(shè)計(jì)有效應(yīng)對(duì)粉塵侵入和高溫工況，且扭力可通過(guò)彈簧調(diào)節(jié)以適應(yīng)0.5g/cm³及以上密度的物料。垂直安裝時(shí)可選450-3000mm加長(zhǎng)軸型號(hào)（PRL-200EB/ED系列），水平安裝需保持接線盒朝下防雨。相比其他原理的料位開(kāi)關(guān)，其抗振動(dòng)、抗沖擊性能較強(qiáng)，并能克服物料粘附問(wèn)題。6922
Key features include maintenance-free operation with all-metal construction and IP65 protection. The motor-driven paddle rotates until material obstruction activates the torque-sensitive mechanism, which simultaneously engages SPDT contacts (10A/250V capacity) and stops the motor. Automatic restart occurs when material level drops below the paddle. Customizable options include flange types (JIS5K65A standard), probe lengths, and paddle configurations (80×80mm standard blade). The device s mechanical design eliminates false signals caused by temperature/humidity changes, with optional extended shafts for deep silos. Noteworthy applications involve fly ash detection in thermal power plants and raw material monitoring in steel mills, where its wear-resistant SUS304 blade ensures long service life.101720
應(yīng)用場(chǎng)景與安裝建議
廣泛應(yīng)用于冶金、化工等行業(yè)的料位控制場(chǎng)景，特別適合存在振動(dòng)或高溫的工況環(huán)境。在水泥廠中可用于熟料倉(cāng)的滿倉(cāng)報(bào)警，安裝時(shí)需在葉片上方加裝防護(hù)板避免物料直接沖擊；檢測(cè)輕質(zhì)物料時(shí)可更換大尺寸葉片提高靈敏度。罐外使用環(huán)境溫度建議不超過(guò)55℃，高粘性物料推薦頂置垂直安裝方式以減少掛料影響。對(duì)于400℃以上超高溫場(chǎng)合，可配合風(fēng)冷裝置使用。產(chǎn)品提供AC100-220V或DC24V多種電源規(guī)格，功耗約2.5-4W，法蘭接口支持JIS標(biāo)準(zhǔn)及其他定制規(guī)格。71519
Typical installations cover material level monitoring in hoppers, bins and silos across mining, food processing industries. For cohesive materials like asphalt, top-mounted vertical installation with extended shaft is recommended to prevent material buildup. The paddle should be positioned away from filling streams, with protective baffles added when handling abrasive substances. In outdoor applications, rain shields are advised for vertical installations. Multiple units installed in same vessel require minimum 1m spacing to avoid shaft entanglement. The product s straightforward mechanical operation makes it suitable for remote locations where complex electronics may fail, while its modular design allows field replacement of components like torque springs or bearings without full disassembly.212425
