As a key component of power and signal transmission, the stable operation of conductive slip ring is crucial to the overall performance of the equipment. In order to ensure that the conductive slip ring is always in the best working condition, Jingpai has summarised a set of scientific and comprehensive conductive slip ring maintenance programme for your reference, the maintenance involves techniques and dosage according to the size of the conductive slip ring and the use of different environments and different, if you need any help, please feel free to contact Jingpai.
Daily Troubleshooting
Daily inspection is an important means of preventing failure. Before each equipment start-up, the appearance of the slip ring should be carefully inspected to see if there are any cracks or deformations in the shell, which are subtle signs that may suggest damage to the internal structure. The contact point between the brush and the slip ring is related to current conduction, so make sure that its surface is smooth and there is no obvious wear and tear or foreign matter attached. At the same time, check whether the connecting lines are loose. Loose lines will increase the contact resistance, resulting in signal transmission distortion and power loss. Once looseness is found, professional tools should be used to tighten it according to the specified torque to ensure reliable electrical connection.
Daily Cleaning
Conductive slip rings in operation are prone to adsorption of dust, debris and other impurities, which will seriously affect the performance of the slip ring. Before cleaning, be sure to cut off the power supply to ensure safe operation. Use a soft, lint-free cloth to gently wipe away dust on the surface of the slip ring and brushes. For stubborn stains, dip the appropriate amount of anhydrous alcohol wipe, but to strictly control the amount of alcohol, to avoid penetration into the slip ring internal damage to precision components and insulation materials.
Lubrication: prolonging life
Appropriate lubrication can reduce the friction between the rotating parts of the slip ring and significantly extend its service life. According to the working environment of the slip ring, choose the appropriate lubricant. In critical rotating parts such as bearings, apply the lubricant evenly in small amounts and at multiple points. Note that too much lubricant will not only fail to improve the lubrication effect, but also attract more dust and form corrosive dirt, which will accelerate the wear and tear of the parts.
Maintenance Frequency
Regular ‘physical examination’ of the slip ring is necessary. However, each slip ring has a different ‘check-up’ cycle. Even between the same slip ring ‘physical examination’ cycle is not the same. If the conductive slip ring is in poor working environment, such as high humidity, high dust, strong electromagnetic interference, high temperature environment or high frequency of use, its maintenance cycle should be shortened accordingly. Jingpai suggests that you should carry out a simple appearance check at the end of each day's work, a weekly cleaning, a monthly check of brush wear and tear, and a comprehensive maintenance every two months. For occasional use of conductive slip ring, the maintenance cycle can be extended to once every three months for appearance check, once every six months for cleaning, and once every year for comprehensive maintenance.
Careful disassembly of the slip ring from the equipment and careful inspection of the internal structure are required for maintenance. Brushes are wearing parts and should be replaced when worn more than halfway to maintain good electrical contact. At the same time, use professional insulation resistance testing equipment to check the insulation performance of the slip ring. If the insulation resistance is lower than the standard range, it indicates a decline in insulation performance, which may lead to leakage, short circuit and other serious faults, at this time, in-depth investigation of the causes of aging, moisture and other reasons for the insulation material, and targeted repair.
To address the problem of cumbersome maintenance of slip rings, JINPAT has developed a variety of maintenance-free slip rings to improve the convenience of using slip rings. This type of slip ring adopts more wear-resistant material and higher sealing technology, which reduces the possibility of failure due to environmental factors. It provides a more convenient choice for some partners.
