導(dǎo)電滑環(huán)用于解決機(jī)電系統(tǒng)360°旋轉(zhuǎn)傳輸絞線問題，從特性上可分為：水下滑環(huán)、高速滑環(huán)、耐高溫滑環(huán)、大功率大電流滑環(huán)、防爆滑環(huán)等。防爆滑環(huán)顧名思義，具有防爆功能，滿足在易爆環(huán)境下安全工作。應(yīng)用優(yōu)先域有石油化工、特種包裝、農(nóng)產(chǎn)品加工、煤礦開采等高危環(huán)境。馳宏導(dǎo)電滑環(huán)廠家分享下關(guān)于防爆滑環(huán)常見的選型誤區(qū)。
防爆滑環(huán)因其自身結(jié)構(gòu)的特殊性，比如外殼組件有良好的密封性和密閉性，內(nèi)部的電弧的處理等。在爆炸性環(huán)境中，選用非防爆滑環(huán)或防爆等級不匹配的滑環(huán)都是重大的安全隱患。
關(guān)于防爆導(dǎo)電滑環(huán)前期選型誤區(qū)一般有以下常見類型：靠前，防爆類型或等級不匹配。認(rèn)為氣體防爆滑環(huán)可以應(yīng)用于粉塵爆炸性環(huán)境中，存在對氣體防爆、粉塵防爆及相關(guān)電氣設(shè)備缺乏正確認(rèn)識，應(yīng)仔細(xì)與廠家確認(rèn)使用環(huán)境，針對性設(shè)計(jì)研發(fā)生產(chǎn)，杜防爆類型不匹配造成生產(chǎn)事故。
第二，防爆滑環(huán)可以防水。認(rèn)為防爆滑環(huán)可以阻止粉塵或爆炸性氣體進(jìn)入內(nèi)部，那么其防護(hù)等級應(yīng)該很高，也具備防水特性，可以暴露在潮濕或戶外嚴(yán)苛環(huán)境下使用。選型前期有此類錯(cuò)誤認(rèn)識一般是對防爆形式和外殼防護(hù)概念缺乏了解。
第三，對工作環(huán)境是否高危的錯(cuò)誤判斷。一般在農(nóng)產(chǎn)品加工優(yōu)先域，比如粉碎加工工序，在其機(jī)電部件中的滑環(huán)都應(yīng)采用防爆滑環(huán)。而此類工作環(huán)境中，加工廠對滑環(huán)的選型會忽略防爆這一屬性，沒有正確地跟導(dǎo)電滑環(huán)廠家溝通，埋下了高危隱患。
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.
