Recently, Xugong Hydraulic Parts Co., Ltd. independently developed the hydraulic cylinders for the dug-armed trolleys successfully delivered. There are 13 kinds of matching cylinders in this series, which not only fills in the blank of the development of domestic excavation construction equipment, but also adds a heavyweight member to Xugong's high-end hydraulic cylinder family.
As a multi-functional tunnel excavation equipment, the dark-duty double-armed trolley requires high process maturity and can adapt to complex working conditions. Therefore, the matching level of parts and components is also a great test. In order to ensure the smooth delivery of the new hydraulic cylinders, the hydraulics company's technical team carried out a comprehensive benchmarking in the product development process, especially for the high pressure, high impact and fast working conditions of the main engine: the product adopted The integrated design of the cylinder valve fully optimizes the structure and installation space of the cylinder, effectively enhances the compactness, and at the same time applies the patented new sealing technology to improve the buffer performance of the cylinder to meet the high-strength operation requirements under severe conditions. Relying on advanced design concepts, the product has high standardization and strong quality stability. All parameters are leading the industry standard, which adds a strong weight to the development of XCMG's core components.
Concerned about surprises
LSAW pipe mill, also known as JCOE steel pipe, it has one welding seam and uses the submerged arc welding process. The specification range is from 325mm to 1420mm. When the diameter of the straight seam submerged arc welding pipe is greater than 914.4 mm, the standard stipulates that steel pipes is allowed to have two straight welding seams.
