Q:Why can the single phase of catenary be used? Why is rail used as loop without electricity?
Commonly used FireWire, relative to the earth, there is voltage, so people standing on the ground will feel electric shock, when standing on the insulating object, it will not get an electric shockIsolated 220V, standing on the ground and touching one of them has nothing to do with it
Q:Discontinuous rail seamless rail effect
Seamless rail is also afraid of thermal expansion, cold contraction, but better than ordinary steel pipe. Thermal expansion and contraction are the laws of physics. When heated, the distance between molecules increases, and the rails extend. Similarly, cold contracts.
Q:Contact surface between train wheel and rail
The two wheel with the rail on the inside, the country for the axle, in the gold processing, the axis of the two end will leave about 50 wire axis file, so that after the bearing is installed, it will not continue to slide inside, play a fixed role, the outer end with nut tightening
Q:What is heavy rail? What is light rail?
General rail means rail laying, dedicated lines, bend and tunnel rails. Among them, the standard track length is 12.50 meters and 25 meters in two, the laying of the curve rail, slightly shorter length, 12.46 meters, 12.42 meters and 24.96 meters, 24.92 meters and other rail, general specification for 38, 43, 45, 50, 60 (kg / m).
Q:The tracks on the stones have what effect?
When the line state occurs (level. Level. Direction), line maintenance work area workers will be used to track lifting up, then ramming into the gravel at the bottom of the sleeper, the line restored to good condition.
Q:What is the method of rail butt welding?
So, if not because of special circumstances such as fracture of the steel rail or rail reaches the service life limit requires replacement or rail damage seriously to reach or exceed the standard replacement, in addition does not recommend the use of thermit welding in rail seamless line.
Q:How to repair welding rail?What kind of electrode is used in rail welding? What's the problem easily?
Repair welding is found when pitting corrosion pits local rail surface, affecting the smooth operation of the train, but the rail has not reached the need to replace the degree, can be used in welding repair: first by flame heated to a certain temperature, and then use the welding welding, using heat to control the cooling speed. When reduced to a certain temperature. The grinding wheel along the longitudinal smoothing.
Q:What's the gauge for the high speed rail?
In 1937, the International Railway Association stipulates: gauge of 1435 millimeters for the international standard gauge of 1520 mm above the gauge is broad gauge, 1067 mm gauge narrow gauge as following.
Q:What is the rail temperature stress?
Thermal stress is also called thermal stress". Stress due to the temperature rise and fall of a body or the temperature of each part of an object. For example, the workpiece is welded by the stress caused by local heating; there is a gap between the rails of the rails to avoid or reduce the possible temperature stress.
Q:Structural classification of rails
The type of rail is expressed by the mass kilogram of rail length per meter. The rails used in China's railways are 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.
