Locale Mix-load Explosive Vehicle Hydraulic Control System

Locale mix-load explosive vehicle integrates conveyance, production and filling with the technical features like safety and credibility, accurate measurement, easy manipulation, environmental-friendly and so on. It is one of the high level of mechanization and automation of production tool. Locale mix-load explosive vehicle is the development trend in the future blasting explosive charge mechanical operation, and it has good prospects in the industry. The hydraulic control system is a key subsystem of the locale mix-load explosive vehicle.The development, current status and trend of the locale mix-load explosive vehicle in the international and domestic is described, meanwhile the requirements for the hydraulic control system are analysed. Then hydraulic control system is designed, and then the production, manufacture, site installation and commissioning of the entire process is completed. With the actual needs of the explosives in the production process, the hydraulic drive is adopted as the actuators of the locale mix-load explosive vehicle. Based on the explosives production processes and performance requirements, the hydraulic system control schematic is designed. According to the design method of hydraulic system, the hydraulic system and component is selected, at the same time, the electro-hydraulic proportional control system is used. Realize the control of the exact ratio of raw materials in the explosives mixed production process, and then reach the requirements of the hydraulic control system for the locale mix-load explosive vehicle.Actual production shows that hydraulic control system of the locale mix-load explosive vehicle reaches the design requirements and can satisfy the explosive production requirements, good performance, stable operation. Explosive hydraulic control system of the locale mix-load explosive vehicle reaches the domestic leading level and the advanced level of the industry.
