Inertia Function Of Hydraulic Coupling

Ningbo E.H Hydraulic Co.,Ltd | Updated: Sep 26, 2017


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.

Hydraulic couplings work smoothly, reliable, can be in a wider range of stepless speed regulation, can be self-lubricating, can make the power machine load-free start-up. Hydraulic Couplings 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, the use of this structure, Hydraulic Couplings 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

When the shaft is connected with the coupling, 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, and the inner cone surface can match the inner sleeve. The common mineral oil is then injected between the internal and external sleeve. Hydraulic Couplings 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 place, an interference fit &mdash is formed, and the process is &mdash as the outer sleeve expands and then shrinks. Hydraulic Couplings But it doesn't actually need to be heated, and the disassembly couplings are as easy as the installation.

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. There is no fretting wear when there is a high-speed vibration or a reverse load.

Super Large hydraulic coupling, can only be installed by heating expansion shrinkage method, Hydraulic Couplings can now be used for cold installation of hydraulic method.
