Maintaining railway switch Complexity of maintaining railway switches depends on several factors including the machinery that is used, operational conditions, and equipment wear degree. Lubrication of the movable elements with anti-friction solid-film coatings enables to reduce friction and wear of the mechanisms, to provide smoothness and reliability of their operating. Repairing electrical scooters: trouble causes, and required actions. Lubricating electrical scooters Operability of electrical scooter depends on many factors starting with proper using of this vehicle and ending with regular maintaining. In case of failures or wear of the components, repairing should be done. Lubricating scooters elements extends its service lifetime, and improves its operating efficiency. Repairing and maintaining railway switches. Basic maintenance works Providing trouble-free and safe running of rolling stocks is the main purpose of repairing and maintaining the railway switches and tracks. Basic works on railway switches maintenance are examine, state control, check of parts sizes, gap between them, cleaning and lubricating movable units. Dry lubricant: difference from liquid lubricants and greases Dry lubricants based on molybdenum disulfide, polytetrafluoroethylene, or other organic and inorganic solid substances are used in the units where use of liquid lubricants and greases is ineffective. PTFE lubricant: special features and application A lubricant based on polytetrafluoroethylene provides reliable and long protection against wear for the parts of metal, rubber, plastic, and wood.
