Design And Experimental Study Of Asphalt Spraying Test Device

With Highway conservation socialization on asphalt spray equipment sprinkled cloth quality constantly upgrade of technology requirements, for meet different asphalt sprinkled cloth equipment spray of actual requirements, design has asphalt spray test device, not only can on installed Qian all nozzle and the spray system spray performance, and spray effect for test, also can on new development of different structure of nozzle, and different media of nozzle and the spray system for development process of experiment research, shortened has installed debugging of time and new products development of cycle, reduced has manufacturing cost. Asphalt spray test equipment development for production companies is necessary, engineering is even more apparent.The basis asphalt sprinkled cloth car and other related technical standards and experimental study of requirements, the asphalt spraying device test scheme, the structure design and control design of the program; the device key pitch system, heat conducting oil system of pump, motor and nozzle, etc, the selection and calculation; design the manipulation and control of soft, hardware system, the realization of the electrical control and safety protection; by the typical in product asphalt spray mechanism and asphalt spraying test device properties were tested and verified the design of test device to achieve the design goal. At the same time through the experimental study, typical nozzle spray characteristics, study the nozzle Shape, spray angle, spraying pressure and spraying height of spraying uniformity, spraying amount and effects of different temperature, different viscosity changes in the external parameters of spraying uniformity and the effects of, to enhance the spraying system performance and actual sprinkling distribution effect.Test device design for this about spraying, use, experiment on highway construction and maintenance, such as peer producers and users reference.
