Technical Parameters Of The Conductive Slip Ring
In the modern industry,the conductive slip ring is required in more and more industry equipment , it could help mechanical operation. For meet real requirement in different industry,CENO keep constantly developing, improving to upgrade parameters of conductive slip ring. CENO has many years experience in the development and application of the slipring,got summering the key parameters in slipring industry to make customer easy understanding and choosing slipring.
Installation dimensions of slip-ring: It is different slipring size for related devices installation space, so slipring with accurate size meet the equipment operating well requirement.
Working voltage of the slip ring: each slip ring has its rated working voltage requirement, and the rated voltage is mainly limited by the insulation material and space.If exceeding its rated voltage could cause defective insulation and internal insulation breakdown even lead to slipring damage.
Rated current of the slip ring: the area and conductivity of the contact material determine the maximum load current of the slip ring.If exceed the rated working current, will cause the temperature rise sharply on the contact point position,cause the contact position air expansion and separating contact point, cause poor contact intermittently, even cause slipring completely damage .
The insulation resistance of the slip ring:Insulation resistance is usually referred to as the conductive resistance between any ring and other rings in a multi-path slip ring.Insulation resistance is affected by insulation material and environmental humidity.Low insulation resistance would cause interference, error code, crosstalk, etc during control signal transmitting. In the case of high voltage, it could generate spark and heat up.
The path number of the sliding ring: the circuit that is connected and current can be passed smoothly, which is called a channel way.If the slip ring does not have the proper number of channels, it will short-circuit or break the path during operation, which will affect the work of the equipment.
Dynamic contact resistance of the slip ring: dynamic contact resistance refers to the fluctuation range of the resistance between rotor and stator in a channel of conductive slip during the slipring working .The influence factor is the same as the contact resistance, and the rotational speed has a great influence on it.
Contact resistance of sliding rings: contact resistance is description for the requirement on reliability of the slip ring.The contact resistance depends on the contact friction secondary material type, contact pressure, the finish of the contact surface and so on.In the case of the contact material, the contact resistance can not be only the lowest, and the requirement of the contact resistance should be reduced properly, which will prolong the life of the slip ring.
Lifespan of the conductive slip ring: the lifespan of the slip ring is the period from the slipring start working to the end of life on it. The life influencing factors of slip ring are contact material type, contact pressure, contact volume, working current, working environment, etc.
Speed of slip ring: the rotational speed of the slip ring is influenced by many aspects, such as contact friction, structure rationality, machining accuracy, and assembly accuracy.
Working temperature of slip ring: the working environment temperature of the slip ring will affect the service life of the slip ring.
The protective property of the slip ring: according to the actual environment of the customer, the slipring will be designed withe requirement of waterproof, explosion-proof ,etc. CENO has the products UP to IP68 protection grade, and explosion-proof slip ring could meeting the explosive gas environment and explosive dust environment.
