導電(dian)(dian)滑(hua)(hua)環(huan)(huan)用(yong)于(yu)(yu)解決(jue)機電(dian)(dian)系統360°旋轉傳(chuan)輸絞線問題,從特性上(shang)可分為:水下滑(hua)(hua)環(huan)(huan)、高速滑(hua)(hua)環(huan)(huan)、耐高溫(wen)滑(hua)(hua)環(huan)(huan)、大功率大電(dian)(dian)流滑(hua)(hua)環(huan)(huan)、防(fang)爆(bao)滑(hua)(hua)環(huan)(huan)等。防(fang)爆(bao)滑(hua)(hua)環(huan)(huan)顧名思義,具有(you)防(fang)爆(bao)功能(neng),滿足在易爆(bao)環(huan)(huan)境下安(an)全工(gong)(gong)作(zuo)。應用(yong)優先域有(you)石油化(hua)工(gong)(gong)、特種(zhong)包裝、農(nong)產品加工(gong)(gong)、煤礦(kuang)開采等高危(wei)環(huan)(huan)境。馳宏導電(dian)(dian)滑(hua)(hua)環(huan)(huan)廠家分享下關于(yu)(yu)防(fang)爆(bao)滑(hua)(hua)環(huan)(huan)常見的選型誤區。
防爆滑環因其自身結(jie)構的特殊性,比如(ru)外(wai)殼(ke)組(zu)件(jian)有(you)良(liang)好的密封性和密閉性,內部的電(dian)弧(hu)的處理等(deng)。在爆炸性環境中,選(xuan)用非(fei)防爆滑環或防爆等(deng)級不匹配(pei)的滑環都(dou)是重(zhong)大的安全隱患。
關于(yu)防(fang)爆導電滑環前(qian)期選型(xing)誤區一般有以(yi)(yi)下常(chang)見類(lei)型(xing):靠(kao)前(qian),防(fang)爆類(lei)型(xing)或(huo)等級不(bu)(bu)匹配(pei)。認(ren)為氣體防(fang)爆滑環可以(yi)(yi)應(ying)用于(yu)粉塵爆炸性環境中,存在對氣體防(fang)爆、粉塵防(fang)爆及相關電氣設備缺乏正確認(ren)識,應(ying)仔細與廠(chang)家確認(ren)使用環境,針對性設計研發生產,杜防(fang)爆類(lei)型(xing)不(bu)(bu)匹配(pei)造成(cheng)生產事故。
第二,防(fang)爆(bao)滑(hua)環(huan)可(ke)以(yi)防(fang)水。認為防(fang)爆(bao)滑(hua)環(huan)可(ke)以(yi)阻止(zhi)粉塵(chen)或爆(bao)炸性氣體進入(ru)內(nei)部,那么其防(fang)護等級應該很高,也具備防(fang)水特性,可(ke)以(yi)暴露(lu)在潮濕或戶外(wai)(wai)嚴苛(ke)環(huan)境下使用。選型前期有此類錯(cuo)誤(wu)認識一般是對(dui)防(fang)爆(bao)形式和外(wai)(wai)殼(ke)防(fang)護概(gai)念缺乏了解(jie)。
第三,對工(gong)作環(huan)境是否高危(wei)的錯誤判斷(duan)。一(yi)(yi)般(ban)在(zai)(zai)農(nong)產品加(jia)工(gong)優(you)先域,比如粉碎加(jia)工(gong)工(gong)序,在(zai)(zai)其機電部(bu)件(jian)中(zhong)的滑(hua)(hua)環(huan)都應(ying)采用防爆(bao)滑(hua)(hua)環(huan)。而此類工(gong)作環(huan)境中(zhong),加(jia)工(gong)廠對滑(hua)(hua)環(huan)的選型會忽略防爆(bao)這(zhe)一(yi)(yi)屬性,沒有正確地跟導電滑(hua)(hua)環(huan)廠家溝通,埋下(xia)了高危(wei)隱患。
Conductive slip ring is used to solve the problem of 360° rotating transmission stranding in electromechanical system. In terms of characteristics, it can be divided into: underwater slip ring, high-speed slip ring, high-temperature resistant slip ring, high-power and high-current slip ring, explosion-proof slip ring, etc. Explosion-proof slip ring, as the name implies, has explosion-proof function, meet the safe work in explosive environment. Application areas are petrochemical, special packaging, agricultural products processing, coal mining and other high-risk environments. Chihong conductive slip ring manufacturers share the common error about the selection of explosion-proof slip ring.
Explosion-proof slip ring due to the particularity of its own structure, such as shell components have good sealing and sealing, internal arc processing, etc. In explosive environment, the selection of non-explosion-proof slip ring or the explosion-proof grade does not match the slip ring is a major hidden danger.
There are the following common types of errors in the early selection of explosion-proof conductive slip ring: First, the explosion-proof type or grade is not matched. It is considered that gas explosion-proof slip ring can be used in dust explosive environment, there is a lack of correct understanding of gas explosion-proof, dust explosion-proof and related electrical equipment, it is necessary to confirm the use environment with the manufacturer carefully, and to prevent production accidents caused by the mismatch of explosion-proof types.
Second, explosion-proof slip rings can be waterproof. It is considered that the explosion-proof slip ring can prevent dust or explosive gas from entering the interior, so its protection grade should be very high, and it also has waterproof characteristics, so it can be used in humid or harsh outdoor environment. In the early stage of selection, such wrong understanding is generally lack of understanding of explosion-proof forms and shell protection concepts.
Third, misjudgment of whether the work environment is dangerous. Generally in the field of agricultural products processing, such as grinding process, in the mechanical and electrical parts of the slip ring should be used explosion-proof slip ring. In this kind of working environment, the factory ignores the explosion-proof property in the selection of slip ring, and fails to properly communicate with the manufacturer of conductive slip ring, which is a high-risk hidden danger.
