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.
