Hydraulic Couplings Work Stably And Reliably

When the hydraulic coupling is used to connect the shaft, the oil injection method has obvious advantages.

Shaft preparation is simple and easy to work. No need for equipment keyway, no cone and thrust ring. When the hydraulic coupling is installed, the tapered outer diameter of the thinner inner sleeve will slide into the bearing. The outer sleeve is thicker, Hydraulic Couplings and the inner cone surface can match the inner sleeve. Then inject common mineral oil between the inside and outside sleeve. The built-in hydraulic lifting device will drive the jacket barrel to connect the cone portion of the inner sleeve.

When the outer sleeve is finally in position, an interference fit is formed-the process is as if the outer sleeve is heated and expanded and then shrunk. Hydraulic Couplings But it does not need to be heated, and the disassembly couplings are as simple and easy to install as they are.

This powerful friction force allows the hydraulic couplings to transfer torque and axial loads to the entire bearing area. The keyway has no stress concentration source. Hydraulic Couplings There is no fretting wear when there is a high-speed vibration or a reverse load.

Super large coupling, can only be installed by the heating expansion shrinkage method, now the use of hydraulic method for cold installation.

Hydraulic couplings work smoothly, reliable, Hydraulic Couplings can be in a wider range of stepless speed regulation, can be self-lubricating, can make the power machine load-free start-up. Power machine speed is equal to pump speed, transmission efficiency is 95---97%, when the pump speed is reduced to 25---30%, the transmission efficiency is 68---70%, in the automatic control of the pump station, stop the pump often due to the inertia of the pump group and the backflow of water in the tube to cause the action of the hammer. However, Hydraulic Couplings the use of this structure, the need to add another hydraulic coupling and its internal oil, if the use of hydraulic coupling, the earth can reduce the water hammer (or hydraulic pump) coupling cold oil equipment, such as the more complex

The hydraulic coupling is composed of a transmission pump wheel and a transmission turbine, the transmission pump wheel 1 and the Power machine shaft connection, transmission turbine 2 and pump shaft connection. Before operation in the coupling filled with working liquid (oil or water), Hydraulic Couplings the power machine after running the drive pump shaft rotation, then the transmission pump wheel in the liquid due to the role of centrifugal force was thrown into the cavity 3, and 3 of the liquid pressure is greater than the transmission turbine 2 pressure, it is also pressed into the transmission turbine wheel, then the transmission turbine blades by hydraulic action and rotation, thus driving the pump shaft rotation. At the same time, the turbine blade again presses the liquid into the inside of the transmission pump wheel, so that the liquid circulates in the cavity and transmits energy continuously.

The hydraulic coupling includes an inner sleeve and a coat of the coaxial bushing, and the outer circumference of the jacket is fixed with a brake disc, and the axis of the brake disc is coincident with the axis of the jacket. The hydraulic coupling of the invention has a brake disc installed on the outer circumference of the jacket, and the brake disc is controlled by the corresponding braking component to realize the braking or locking operation of the coupling.
