Wide provided suitable for busy trunk, also can be laid in tunnel and station floor maintenance difficulties, stone or soil subgrade are laid, but the mud pumping in the diseases of roadbed must be laid on the roadbed diseases after renovation. The main advantages of the wide sleeper circuit are: the suborbital sinking is small. The vibration acceleration is smaller than the concrete sleeper line, which gradually slows down and stops after laying. So the line maintenance work is greatly reduced, about a third of the general concrete sleeper line. The track is easy to keep clean. Dirt is not easy to break into the bed and prolong the repair cycle of the route. The line is smooth and stable, which is conducive to high-speed operation and the laying of seamless circuit. The disadvantage is that the cost is higher, and it is more difficult to change the shop on the busy trunk line
Note that the epoxy adhesive curing speed varies depending on temperature. At higher temperatures it dries faster, but has less resistance and firmness. During the winter you might also leave a few minutes in double boiler pots, and try to take certain temperature (never to be more than 30 degrees at all), like too cold, the information becomes more complicated, thus a viscous mix.
The semi semi-automatic closing interval, the long train head over the outbound signal generator (the track circuit not on the outbound side of the station).
In good communication under the condition of recording device and switching equipment, for the following content can use wireless dispatching telephone, to convey to the value multiplied driver, vehicle operation dispatching command, meet the speed limit operation scheduling command, specified by the into the relationship between interval (standing) in front of the second station attendant tip the driver.
Self-cleaning filter to overcome the traditional filtering products, quantity is small, vulnerable to contamination jams, filtering, part of the need to remove the cleaning and unable to monitor the state of the filter and so on shortcomings, with the raw water filter and the function of the automatic filter for cleaning pollution.
The biggest advantage of elastic filter is that it is free of maintenance, which can be automatically cleaned and avoided. Product features: free maintenance, can automatically clean Cleaning time is short (3 seconds) the equal and can swing can replace spring open gap mesh type, drum, bag filter, etc To reduce the comprehensive cost scope of application: automobile industry (processing machinery, cleaning machinery, etc.) machine tool industry (processing coolant, burr processor, etc.) the food industry (drainage treatment, Fried residue recycling) swimming pool, pool, spa and other places of large circulating water filter High pressure water cutting, stripping device cooling tower circulating water filter (sandstone, wood chip, foreign body removal)
