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
Filter outlet pressure difference of change, when the differential pressure to set data, control device for hydraulic control valves, motor drive signal, caused by the following action: motor driving brush rotation, the filter cleaning, emission control valve to open at the same time, the whole cleaning process for dozens of seconds, when the end of the cleaning, close the valve, the motor stop running, system back to its initial state, began to filter into the next process
