It is also known as welding long rail line, which is a kind of line that welded normal rails without rail seam. The welding rail is not less than 200 meters long, and the actual application is usually 800~1000 meters or more. The long track is laid in the specified temperature range and fixed on the pillow. The long rail ends with a rail joint, while the middle part cannot scale up and down with the temperature. Therefore, there will be a great temperature pressure in the middle of the rail during the summer, which will produce a great temperature tension in winter. The greatest pressure on the rail and tension according to the years of rail laying and the highest temperature and minimum temperature calculation, rail tracks the maximum pressure should not cause to drum up by maximum tension should not cause rail fracture
The filter consists of the shell, the multi-element filter element, the anti-flushing mechanism, and the differential pressure controller. Casing of diaphragm plate inside cavity can be divided into upper and lower two cavity, the cavity is equipped with multiple filter core, so that make full use of the filter space, significantly reduced the volume of the filter, are installed in the inferior vena recoil wash suction cups. At work, the turbid solution enters the filter chamber through the entrance and enters the inner cavity of the filter core through the diaphragm hole. The impurities that are larger than the gaps in the filter core are truned away, and the net fluid reaches the upper chamber through the gap and is finally sent out from the outlet.
The fully redesigned 2013 Honda Accord returns to the top level in the family-sedan class with a number of new specifications. Apart from a roomy and high-quality interior, the car's styling is visibly less bulky. Besides, Honda adds power- and efficiency-enhancing direct-injection technology to the Accord's standard 2.4-liter four-cylinder engine. With this four-cylinder, performance is markedly improved. What's more, each car also incorporates antilock disc brakes, active front head restraints, stability and traction control, front seat side airbags and side curtain airbags.
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
