KENT, OH消息，Rotron直流無(wú)刷無(wú)縫水循環(huán)泵在重型搬載運(yùn)輸、市政交通應(yīng)用中，壽命可達(dá)60,000小時(shí)。其無(wú)縫設(shè)計(jì)和無(wú)刷電機(jī)技術(shù)所達(dá)到的可靠性和優(yōu)化測(cè)試性能可達(dá)到18年的使用年限。 無(wú)縫設(shè)計(jì)提供了防漏保護(hù)和抵抗苛刻環(huán)境的能力，如熱水噴濺、鹽霧、霧氣、振動(dòng)。磁性泵結(jié)合直流無(wú)刷電機(jī)技術(shù)，不用潮濕密封或是更換,可長(zhǎng)久使用。此連接方法不用使系統(tǒng)排水就能輕松移走電機(jī)。 其電子換向直流無(wú)刷電機(jī)通過(guò)排除刷子維護(hù)和關(guān)聯(lián)電機(jī)的出錯(cuò)，在操作過(guò)程中提供免維護(hù)操作。稀土磁體可實(shí)現(xiàn)高效且低電流的效果，"O"型密封保護(hù)可防止其它物品掉入，重型電機(jī)構(gòu)造滿足運(yùn)輸工具的需求。 這些Rotron冷卻液泵可有兩種型號(hào)（47和64），容量分別為18和26加侖，輸入電壓有12伏直流輸入和24伏直流輸入兩種，依型號(hào)而定。所有都為4.5年質(zhì)保，此電機(jī)還可以定制以滿足流行的應(yīng)用需求。 阿美特克技術(shù)工業(yè)產(chǎn)品是電子儀表及電動(dòng)機(jī)械設(shè)備全球領(lǐng)先生產(chǎn)商阿美特克有限公司的組成單位，年銷售額超過(guò)21億美元。 更多信息請(qǐng)登錄：www.ametektechnicalproducts.com [font=times]original text [/font] [font=times]Rotron Brushless DC Water Circulation Pumps Can Deliver 60,000 Hours of Service Life in Buses and Construction Vehicles [/font] [font=times][color=#708090]KENT, OH - Rotron brushless DC sealess water circulation pumps can deliver up to 60,000 hours of service life onboard heavy-duty transit buses, construction vehicles, and off-highway equipment. Their sealess design and brushless motor technology both contribute to reliability and optimized performance field-tested for 18 years. The sealess design offers leak-proof protection and the capability to resist harsh environmental conditions, such as hot-water spray, salt, fog, shock, and vibration. The pump magnetically couples to the brushless DC motor without a wet seal to wear or replace. This coupling method also enables easy motor removal without requiring system draining. Their electronically commutated brushless DC motor provides virtually maintenance-free operation over time by eliminating brush maintenance and associated brush motor failure. Rare-earth magnets promote high efficiency and low current draw; "O" ring seals protect against the elements; and heavy-duty motor construction meets demanding transit bus and construction equipment requirements. These Rotron coolant pumps are available in two frame sizes （47 and 64） with 18 or 26 gallon capacities and in 12VDC or 24VDC input voltages, depending on model. All carry 4.5-year warranties more than double the industry standard and can be customized to satisfy particular application requirements.
