AI Technical Summary
The hydraulic system of existing combined shield tunneling machines is prone to air cavitation when the towing cylinder is pulled quickly, which can lead to damage. Furthermore, it cannot achieve flexible relative position adjustment, affecting the service life and efficiency of the equipment.
The cylinder adopts a dual-chamber design. Through bidirectional control of the oil supply and return pipelines, combined with the setting of solenoid valves, one-way throttle valves, and balance valves, the cylinder can achieve bidirectional push-pull and active pressure compensation, reducing the possibility of air intake cavitation and improving adjustment accuracy and stability.
It effectively reduces the possibility of air cavitation in the hydraulic cylinder, improves the service life and adjustment accuracy of the hydraulic cylinder, ensures that the equipment can operate flexibly in complex terrain, and enhances the stability and efficiency of the equipment.
