Technical Field

Large-scale equipment requires the assistance of comprehensive hydraulic support equipment to perform daily maintenance, scheduled inspections, minor repairs, and medium-scale repairs of the hydraulic systems. This equipment is used to accurately measure three parameters of the large-scale equipment: overall pressure, flow rate, and oil solid particle size. Therefore, this comprehensive hydraulic support equipment is characterized by high frequency of use and important function.

[0003] The integrated hydraulic support equipment is encapsulated together through hardware and piping connections. Operation and data display are controlled and presented on a display panel via measurement and control software.
