Production Equipment

Our company specializes in the production of hydraulic motors. With advanced processing centers, we ensure the precise processing of core components, guaranteeing stable product performance. Each motor is rigorously tested on professional test benches. From production to quality inspection, we strictly control every process to provide customers with reliable and efficient hydraulic power solutions.

Adhering to the development philosophy of high-end and intelligent advancement, Qingdao Yushan Intelligent Technology Co., Ltd. has introduced world-class production and testing equipment, establishing a comprehensive equipment support system encompassing "processing, testing, and calibration". The core processing stage is equipped with 12 Demag CNC precision machining centers imported from Germany, 8 Fanuc five-axis linkage machine tools from Japan, and 20 fully automatic CNC grinding machines. The five-axis linkage machine tools enable one-time processing of complex structural core components such as rotors, stators, and valve groups, eliminating the need for multiple clamping operations and effectively avoiding clamping errors. The processing accuracy can reach ±0.005 millimeters, significantly surpassing the industry average of ±0.01 millimeters, laying a solid foundation for the stable operation of products. Additionally, the company has equipped a fully automatic component cleaning line and vacuum drying equipment to thoroughly remove iron chips and cutting fluid residues during the processing process, preventing component rusting that could affect product lifespan. For vulnerable components such as seals, a dust-free assembly station is specially set up to ensure assembly accuracy. Furthermore, the company has established an equipment account management system that details the purchase time, operating parameters, and maintenance records of each equipment. Regular technical upgrades are conducted in collaboration with equipment manufacturers to ensure that equipment performance always keeps pace with industry-leading technology.

The testing department is equipped with a professional hydraulic motor performance testing laboratory spanning 800 square meters. It is outfitted with eight sets of intelligent hydraulic test benches, high and low temperature environment simulation testing equipment, salt spray corrosion testing equipment, and durability testing devices, enabling comprehensive testing from conventional performance to adaptability in extreme environments. Before each motor leaves the factory, it must undergo a 72-hour continuous full-load durability test, a high and low temperature environment adaptability test ranging from -40°C to 60°C, a 1000-hour salt spray corrosion test, and testing for 12 core performance indicators such as pressure, torque, flow rate, and noise. For customized products, additional special tests will be conducted based on the actual working conditions of the customer. For example, motors customized for tunnel engineering will undergo continuous operation testing in high vibration and high dust environments; motors customized for marine engineering will undergo enhanced corrosion resistance and high pressure resistance testing. Furthermore, the company has established a regular maintenance and upgrade mechanism for equipment, with a team of 15 professional equipment engineers responsible for daily debugging, calibration, and maintenance work. Precision calibration is conducted monthly, and comprehensive maintenance is carried out quarterly, ensuring that the equipment is always in optimal operating condition, laying a solid foundation for product quality from the hardware level.
