Hualing heavy truck CAN bus control system won the national patent


The “Heavy Truck CAN Bus Control System” jointly declared by employees of Zhouling Feng, Ma Ming, and Wan Wei of the Hualing Technology Department obtained the patent certification from the State Intellectual Property Office.

The patent refers to a CAN bus control system for heavy trucks. The heavy truck includes a chassis, an engine, and a meter assembly. The CAN bus control system has an instrument control module, a front control module, a middle control module, and a middle control module. , tail control module and door control module, each control module is connected to each other through the CAN bus. The heavy truck adopts the CAN bus control system, which overcomes the problems of reduced reliability and difficult arrangement due to the increase of electrical appliances in a limited space, thereby improving the reliability of the vehicle.

Double Suction Pump

As an important form of Centrifugal Pump, double suction pump is widely used in engineering because of its high lift and large flow. The impeller of this pump type is actually a combination of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is horizontally opened, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable.
