  • 防爆滑环选型误区
  • 本站编辑:杭州以铁精密机械有限公司发布日期:2022-02-23 17:26 浏览次数:

导电滑环用于解决机电系统360°旋转传输绞线问题,从特性上可分为:水下滑环、高速滑环、耐高温滑环、大功率大电流滑环、防爆滑环等。防爆滑环顾名思义,具有防爆功能,满足在易爆环境下安全工作。应用优先域有石油化工、特种包装、农产品加工、煤矿开采等高危环境。驰宏导电滑环厂家分享下关于防爆滑环常见的选型误区。

防爆滑环因其自身结构的特殊性,比如外壳组件有良好的密封性和密闭性,内部的电弧的处理等。在爆炸性环境中,选用非防爆滑环或防爆等级不匹配的滑环都是重大的安全隐患。

关于防爆导电滑环前期选型误区一般有以下常见类型:靠前,防爆类型或等级不匹配。认为气体防爆滑环可以应用于粉尘爆炸性环境中,存在对气体防爆、粉尘防爆及相关电气设备缺乏正确认识,应仔细与厂家确认使用环境,针对性设计研发生产,杜防爆类型不匹配造成生产事故。

第二,防爆滑环可以防水。认为防爆滑环可以阻止粉尘或爆炸性气体进入内部,那么其防护等级应该很高,也具备防水特性,可以暴露在潮湿或户外严苛环境下使用。选型前期有此类错误认识一般是对防爆形式和外壳防护概念缺乏了解。

第三,对工作环境是否高危的错误判断。一般在农产品加工优先域,比如粉碎加工工序,在其机电部件中的滑环都应采用防爆滑环。而此类工作环境中,加工厂对滑环的选型会忽略防爆这一属性,没有正确地跟导电滑环厂家沟通,埋下了高危隐患。

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.
