Working principle and structure of hydraulic slip ring

Hydraulic slip ring, also known as hydraulic rotary joint or oil distributor, is a common hydraulic transmission joint widely used in construction machinery, fixtures, high-speed machine tools, etc. Hydraulic slip ring can achieve 360 degree rotation in any direction for oil distribution or other liquid work. Its structure is a base with a core shaft fixed on the base, which is used to transmit various gases and liquids in automatic workstations and some mechanical equipment that requires 360 degree rotation. There are many media supported by rotary joints, such as hot oil, steam, compressed air, water, coolant, and other media that can be used.

The main function of hydraulic slip rings is to transfer pressure oil or other fluids to hydraulic rotary cylinders, causing the piston rod to move left and right, and driving the sliding shaft to drive the jaws, thereby achieving radial release and clamping of the chuck. Hydraulic rotary joints are a type of rotary joint specifically used for low-speed and high-pressure multi medium, multi-channel equipment, serving equipment such as machining center rotary workbenches, hydraulic workstations, coilers, converters, large bag rotary workbenches, hydraulic machinery, and multi-channel high-pressure controllers. The connection method of hydraulic rotary joints can be selected according to the working conditions. There are independent pipelines inside, which can be selected according to different working conditions to maximize efficiency. There are two precision bearings inside the rotary joint, which operate smoothly, persistently, reliably, firmly, and flexibly. The friction coefficient is small, so it can operate at high speed. Generally speaking, hydraulic rotary joints are usually used to transport hydraulic media to hydraulic actuators and other equipment above rotating equipment. The oil inlet joint is connected to the oil circuit of deep-sea cutting pile equipment, and the two oil outlet joints are respectively connected to the oil cylinder of deep-sea cutting pile equipment; Through gear transmission, the outer and inner parts of the rotary joint form relative rotational motion; Hydraulic oil flows into the oil tank through the oil inlet joint and the oil inlet hole in sequence. The hydraulic oil in the oil tank then provides power oil to the oil cylinder of the deep-sea cutting pile equipment through two oil outlet holes I, two oil outlet holes II, and two oil outlet joint, and the oil cylinder completes the expansion and contraction action It solves the problem of supporting the fixed and rotating ends of deep-sea cutting pile equipment and supplying hydraulic oil.
