Recently, Xugong hydraulic parts company K series of new lightweight cylinders to complete the old and new switch to achieve Xugong Shi Weiying 26 meters to 56 meters full support of pump products . At the pre-product identification meeting, the appraisal committee unanimously held that "the main performance indexes of pump-truck cylinders based on lightweight technology ( pump technology ) have reached the leading level of similar products in China.
Last year, the hydraulic parts company actively carried out the light truck fuel tank project for the XCMG company K Series concrete pump to provide complete machine matching. Since August last year, K-series main models for mainframe companies have been pilot-tested and the bulk supply has been gradually realized. By May 2013, the K series basic type spectrum cylinder design and process compilation have been completed with the technical capability and industrialized production capability of batch-supplying light-weight fuel tanks for all K-series spectrum-type pump trucks.
In the research and development stage, the hydraulic parts company overcomes the technical problems of the reliability of the lightweight fuel tank, that is, the change of material and structure to ensure that the reliability of the fuel tank is significantly improved under the premise of achieving the weight reduction. Aiming at the special material and structure design of lightweight fuel tank, the process design adopts a two-step strategy of small-batch trial production process and industrial production process. In small batch production to ensure processing accuracy, while the technology research, the use of high-end processing equipment, both precision and efficiency, the final realization of the industrial production cylinder.

Nuts are Tight junction parts of mechanical equipment. Nuts and bolts of the same specification can only be connected together through the inner thread. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between two threads is 0.7mm); The same applies to American products, such as 1/4-20 nuts that can only be paired with 1/4-20 screws (1/4 refers to a nut with an inner diameter of approximately 0.25 inches, and 20 refers to 20 teeth per inch).
