Research And Development Of City River Dredging Machine

The traditional bruised mechanical equipments are applied to port, wide rivers, lakes, etc. The equipments include the digging sand ship, homework, and the auxiliary ship and buoy, pipe and other auxiliary equipment. Generally city rivers are biased in which have no water. The technology exists that the construction cost inefficient, safety small and easy to create the second pollution and shortcomings. Therefore a small, economical and adequate power unit should be designed. The design the solution to the city on the bruised of inefficient, high consumption of homework to make clear bruised efficient, development and implementation of rational energy use, the reduction in energy conservation is of great practical significance.The dynamic match is studied on city dredging machine, which includes the distribution of dredging machine parts, sections of the work in the best part of the engine, and reasonable use of energy. It is the purpose and requirement to implement the work in the city. In this paper, we carry out a series of studies of dredging machine with sizing and power distribution, including all aspects of the dynamic match. The main contents include the following:First, according to the work environment of machine, it is used as a reasonable walking mechanism, dredging pump, hydraulic system in this design with shape and structure of each component. Which should be carefully calculated to the required power, then a reasonable choice based on the model national standard models, the power required to dredging.Second, based on power dredging equipment required, the appropriate choice of engines with power matching, according to the actual situation of machine, converting the original layout of the diesel engine structure, which is suitable for use in dredging the car, and further select the appropriate power source and the dredging pump, the hydraulic pump of the transmission process.Final, dredging machine at a reasonable choice and match the power, the detail calculation of dynamic and economy, we obtained:the diesel engine power matching components, but also the full application of power and the best economic performance.
