跑偏開關(guān)PK1-2BW 廠家
產(chǎn)品概述
跑偏開關(guān)PK1-2BW是一種專為帶式輸送機設(shè)計的安全保護裝置，用于實時檢測輸送帶的跑偏情況。該產(chǎn)品采用兩級動作設(shè)計，當(dāng)輸送帶發(fā)生輕微偏移時觸發(fā)一級報警信號，若偏移加劇則觸發(fā)二級停機信號，有效防止物料溢出或設(shè)備損壞。其結(jié)構(gòu)緊湊，安裝便捷，適用于冶金、煤炭、電力、化工等多種工業(yè)場景。外殼采用高強度鋁合金材質(zhì)，表面經(jīng)過靜電噴涂處理，具備優(yōu)異的防腐蝕和防水性能，可在惡劣環(huán)境下長期穩(wěn)定工作。1612
Product Overview
The PK1-2BW belt deviation switch is a safety protection device specifically designed for belt conveyors, monitoring real-time belt misalignment. It features a two-stage action mechanism: the first stage triggers an alarm signal upon minor deviation, while the second stage initiates an emergency shutdown if the deviation worsens, effectively preventing material spillage or equipment damage. With a compact design and easy installation, it is widely used in industries such as metallurgy, coal mining, power generation, and chemical processing. The housing is made of high-strength aluminum alloy with electrostatic coating, offering exceptional corrosion resistance and waterproof performance for reliable operation in harsh environments. 255
核心功能
PK1-2BW通過立輥與輸送帶邊緣接觸實現(xiàn)檢測功能。立輥與皮帶間距可調(diào)（通常為50-100mm），當(dāng)皮帶偏移擠壓立輥至一級角度（如12°）時輸出報警信號；若偏移持續(xù)擴大至二級角度（如30°），則輸出停機信號。產(chǎn)品支持自動復(fù)位，故障排除后立輥恢復(fù)初始狀態(tài)。適用于常規(guī)皮帶機、斗式提升機、港口裝卸系統(tǒng)等設(shè)備，可集成到自動化控制系統(tǒng)實現(xiàn)跑偏自動調(diào)整。179
Key Features
The PK1-2BW utilizes a roller mechanism to detect belt edges. The adjustable roller spacing (typically 50-100mm) allows customization based on conveyor width. When the belt deviates and presses the roller to the first-stage angle (e.g., 12°), an alarm signal is activated; if deviation reaches the second-stage angle (e.g., 30°), a shutdown signal is sent. The device supports automatic reset after troubleshooting. Compatible with belt conveyors, bucket elevators, and port handling systems, it can be integrated into automated control systems for real-time deviation correction. 610
適用行業(yè)
該產(chǎn)品廣泛應(yīng)用于散料輸送領(lǐng)域，如礦山中的原煤輸送、水泥廠的原料傳輸、發(fā)電廠的燃料供應(yīng)線等。其防塵密封設(shè)計和耐高低溫特性（-40°C至60°C）使其適應(yīng)極端工況，如露天礦區(qū)或高濕度環(huán)境。同時，在碼頭裝卸系統(tǒng)和自動化倉儲物流中也能發(fā)揮穩(wěn)定保護作用。51121
Industry Applications
The device is widely applied in bulk material handling, including raw coal transportation in mines, raw material transfer in cement plants, and fuel supply lines in power stations. Its dust-proof sealing and temperature resilience (-40°C to 60°C) ensure performance in extreme conditions like open-pit mines or humid environments. It also provides reliable protection for port loading systems and automated warehouse logistics. 1220
設(shè)計與安裝
產(chǎn)品采用模塊化設(shè)計，立輥高度可調(diào)（位于皮帶邊緣下1/3處），安裝支架可通過螺栓直接固定于輸送機機架。建議每30-50米安裝一對開關(guān)，頭部、尾部及易跑偏段為重點布設(shè)區(qū)域。配套電纜接口支持快速接線，簡化現(xiàn)場部署流程。11316
Design & Installation
The modular design includes an adjustable roller (positioned at the lower 1/3 of the belt edge) and bolt-on mounting brackets for direct attachment to conveyor frames. Recommended installation interval is 30-50 meters per pair, with emphasis on head/tail sections and known deviation-prone areas. Pre-wired cable interfaces simplify on-site deployment. 722

工作原理
跑偏開關(guān)固定在輸送機皮帶支架上，動作桿靠在皮帶一側(cè)，當(dāng)皮帶跑偏時，迫使動作桿偏離，觸動報警微動開關(guān)。如果繼續(xù)偏離，觸動另一組觸點，輸送機就會保護性停機。
主要技術(shù)數(shù)據(jù)
輸出觸點：兩組SPDT，10A/500V；
動作角度：第10度，第二級20度；
作用力：3-4kg；
動作桿距皮帶邊緣安裝距離：25-75mm；
出線接口螺紋：3/4″NPT，兩個；
防護等級：IP65，適合室外安裝。
跑偏開關(guān)（Belt Sway Switches）又稱防偏開關(guān)，也叫兩級跑偏開關(guān)。用于檢測帶式輸送機運行中的跑偏現(xiàn)象，按皮帶實際跑偏量輸出報警或停機信號，可有效的防止由皮帶跑偏而產(chǎn)生的事故，是一種帶式輸送機的保護裝置。
安裝和調(diào)整
1.跑偏開關(guān)設(shè)在輸送帶兩側(cè)，立輥應(yīng)與輸送帶邊平面垂直，并使輸送帶兩邊位于立輥高度1/3處。
2.跑偏開關(guān)立輥與輸送帶正常位置的間距宜為50～100mm。
3.跑偏開關(guān)數(shù)量應(yīng)根據(jù)輸送機長度、類型及布置情況進行確定。一般應(yīng)在輸送機頭部、尾部、凸弧段、凹弧段和在輸送機中間位置進行設(shè)置。（注：當(dāng)輸送機較長時，在輸送機中間位置可每隔30～35米設(shè)1對）
4.跑偏開關(guān)應(yīng)通過安裝支架與輸送機中間架連接，開關(guān)支架應(yīng)在輸送機安裝完成后與輸送機機架焊接，跑偏開關(guān)與跑偏開關(guān)支架用螺栓固定。
適用范圍
兩級跑偏開關(guān)廣泛用于冶金、煤炭、水泥建材、采礦、電力、港埠、冶金、化工等域的各種帶式輸送設(shè)備。
