The Hydraulic Coupling Plays The Safe Protection Function

Ningbo E.H Hydraulic Co.,Ltd | Updated: Sep 05, 2017


The hydraulic coupling is composed of a transmission pump wheel and a transmission turbine, such as the figure, 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, 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

Characteristics and use of hydraulic couplings

(1) Compact structure, small quality, small radial size, small moment of inertia, easy to connect with other transmission parts. Not affected by metal fatigue, can be a longer time to guarantee the limited transmission of the predetermined torque. Can be more sensitive to overload safety protection role. Hydraulic Couplings By controlling the pressure injected into the pressure oil, the transfer torque is adjusted in a larger range. Transmission balance, can be buffered, damping, suitable for the positive and negative rotating conditions. Replacement of vulnerable parts (cutting pipe) more convenient, shorten the auxiliary work hours. Hydraulic Couplings Convenient maintenance and low cost.

The hydraulic coupling can be matched with other transmission parts, such as universal coupling, tooth type coupling, diaphragm coupling, fan block elastic coupling, Hydraulic Couplings flexible coupling such as elastic movable pin coupling, and gears, shafts, etc., to transfer torque, and play a safe protection role.
