SJ-350-HB-F料位開關
產(chǎn)品概述
SJ-350-HB-F阻旋式料位開關是一款專為固態(tài)物料（如粉狀、顆粒狀、塊狀及膠狀物料）設計的物位控制設備。其核心采用不銹鋼材質(zhì)葉片，通過永磁電機驅(qū)動旋轉(zhuǎn)，當物料接觸葉片時觸發(fā)機械阻力并輸出開關信號，實現(xiàn)料位監(jiān)測。該產(chǎn)品適用于化工、塑料、水泥、制藥、飼料及食品等行業(yè)，具有輕便易裝、密封性強、過載保護等特點，可針對不同物料密度通過調(diào)節(jié)彈簧拉力優(yōu)化靈敏度。
The SJ-350-HB-F Rotary Paddle Level Switch is designed for solid materials (including powders, granules, lumps, and viscous substances). Its stainless steel blade is driven by a permanent magnet motor. When material contacts the blade, mechanical resistance triggers a switch signal for level monitoring. Suitable for industries like chemicals, plastics, cement, pharmaceuticals, and food processing, it features compact installation, robust sealing, and overload protection, with adjustable spring tension to adapt to varying material densities.
技術特點
該設備采用三層軸承支撐結(jié)構(gòu)，運行穩(wěn)定性高，并配備防塵油封設計，有效防止粉塵沿軸滲入。其扭力調(diào)節(jié)機構(gòu)可靈活適應物料比重變化（≥0.5g/cm³），葉片過載時自動觸發(fā)離合器保護電機。工作溫度范圍覆蓋-10℃至80℃（高溫型可定制至400℃），防護等級達IP65，適用于惡劣工業(yè)環(huán)境。
Technically, the device employs a triple-bearing support structure for enhanced stability, coupled with a dust-proof oil seal to prevent particle ingress. The torque adjustment mechanism adapts to material density changes (≥0.5g/cm³), while an automatic clutch protects the motor during blade overload. Operating temperatures range from -10℃ to 80℃ (high-temperature versions customizable up to 400℃), with IP65 protection for harsh industrial conditions.
應用場景
典型應用包括敞開或密閉料倉的物料高低限位報警，如水泥倉粉料監(jiān)測、飼料生產(chǎn)線顆粒控制等。安裝時需避開進料口直沖位置，側(cè)裝建議葉片與水平面呈10°-20°夾角以減少沖擊，垂直安裝可加裝防雨罩。
Typical applications include high/low-level alarms in open or sealed silos, such as powder monitoring in cement bins or granule control in feed production lines. Installation requires avoiding direct material flow impact, with side-mounting at a 10°-20° tilt to minimize沖擊. Vertical installations may include rain shields for outdoor use.
維護與可靠性
機電分離式設計簡化維護流程，無需拆卸整體即可檢修內(nèi)部組件。葉片轉(zhuǎn)速為1RPM（轉(zhuǎn)/分），低功耗設計（4W）搭配10A/250VAC觸點容量，確保長期可靠運行。
Maintenance is streamlined via a modular機電分離 design allowing partial repairs without full disassembly. With a blade speed of 1RPM and low power consumption (4W), the 10A/250VAC contact capacity ensures long-term reliability.

SJ-350-HB-F料位開關
阻旋料位開關產(chǎn)品原理：阻旋料位開關是一種用于固態(tài)物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制器。其利用永磁電機帶動葉片旋轉(zhuǎn)，當被檢測物料上升至葉片位置時，葉片轉(zhuǎn)動受阻，該阻力通過傳動軸傳遞到接線盒內(nèi)的檢測裝置，檢測裝置則向外輸出一個開關信號，并切斷電機電源使葉片停止轉(zhuǎn)動。當物料下降時，葉片阻力消失，檢測裝置便依靠彈簧的拉力恢復到原始狀態(tài)，葉片恢復旋轉(zhuǎn)狀態(tài)。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業(yè)得到了的應用。
