技術(shù)特點(diǎn)
該堵煤開關(guān)采用微電機(jī)驅(qū)動檢測葉片旋轉(zhuǎn)的工作原理，當(dāng)物料阻礙葉片轉(zhuǎn)動時，內(nèi)部機(jī)構(gòu)會觸發(fā)雙刀雙擲繼電器輸出信號（DPDT），響應(yīng)時間僅20毫秒。產(chǎn)品支持AC220V電源輸入，環(huán)境溫度適應(yīng)范圍-40℃~60℃，最大電纜長度可達(dá)45米。特的全封閉油封設(shè)計能有效防止粉塵滲入，延長設(shè)備使用壽命。安裝時需避開物流直接沖擊方向，通常嵌裝于落煤斗倉壁或溜槽側(cè)壁，建議與入料口保持1米以上水平距離以確保檢測準(zhǔn)確性。214
功能優(yōu)勢
HQKDS-1628AGLAC220V具備抗干擾性強(qiáng)、信號穩(wěn)定的特點(diǎn)，其檢測結(jié)果不受物料濕度或溫度變化影響。高耐磨的316L不銹鋼探桿和葉片設(shè)計可抵抗酸堿腐蝕，特別適合燃煤輸送場景。產(chǎn)品支持常開/常閉形式切換，可通過彈簧自動復(fù)位，故障排除后無需人工干預(yù)即可恢復(fù)待機(jī)狀態(tài)。此外，射頻防護(hù)功能使其在強(qiáng)電磁干擾環(huán)境下仍能可靠工作，靜電火花防護(hù)設(shè)計則提升了易燃環(huán)境中的安全性。61214
應(yīng)用場景
本產(chǎn)品廣泛應(yīng)用于火力發(fā)電廠輸煤系統(tǒng)、礦山輸送帶、水泥廠原料倉等場景。在皮帶輸送機(jī)系統(tǒng)中，可安裝于溜槽三分之二高度處作為重度堵塞檢測點(diǎn)，或與振動電機(jī)聯(lián)動實(shí)現(xiàn)輕度堵塞自動振打功能。其模塊化設(shè)計允許傳感器與變送器分離安裝，便于高空作業(yè)維護(hù)。典型應(yīng)用包括：檢測給煤機(jī)落煤管堵塞、預(yù)防煤倉高料位溢出、監(jiān)控港口卸料系統(tǒng)物料流通狀態(tài)等。2614
Product Overview
The HQKDS-1628AGLAC220VÄ stainless steel coal blockage switch is a detection device specifically designed for industrial material conveying systems. Constructed from 304 stainless steel, it offers exceptional corrosion and wear resistance. This product primarily monitors material blockages in coal conveyor belts, chutes or silos, triggering instant alarms or shutdown signals when accumulated materials reach preset positions, effectively preventing equipment damage or production interruptions caused by coal jams. Its compact structure suits harsh industrial environments with high temperatures and dust, serving as a critical protection device in power plants, metallurgy, cement plants and ports.13
Technical Features
Operating on a micro-motor driven rotating vane principle, this switch activates DPDT relay output within 20ms when material obstructs the vane. It supports AC220V power input with an operational temperature range of -40℃~60℃ and maximum cable length of 45m. The fully enclosed oil-sealed design effectively prevents dust ingress, extending service life. Installation requires avoiding direct material flow impact, typically embedding in coal hopper walls or chute sidewalls, with recommended 1m horizontal clearance from feed inlets for detection accuracy.214
Functional Advantages
The HQKDS-1628AGLAC220V delivers stable anti-interference performance unaffected by material humidity or temperature fluctuations. Its 316L stainless steel probe and vane resist acid/alkali corrosion, ideal for coal handling. Configurable as normally open/closed with spring auto-reset function, it requires no manual intervention post-fault clearance. RF shielding ensures reliability under electromagnetic interference while electrostatic spark protection enhances safety in combustible environments.612
Applications
Widely deployed in coal-fired power plants, mining conveyors and cement raw material silos, this device can be installed at two-thirds height of chutes for severe blockage detection or synchronized with vibrators for mild clogging self-cleaning. Modular design allows separate sensor/transmitter mounting for easier high-altitude maintenance. Typical uses include: monitoring feeder pipe blockages, preventing silo overflows, and tracking material flow in port unloading systems.2614
