Hydraulic Couplings Work Stably And Reliably

Ningbo E.H Hydraulic Co.,Ltd | Updated: Aug 02, 2017


The hydraulic coupling is generally applied to the connection between shaft and shaft, shaft and gearbox output flange or main power output flange of the main propulsion device of the ship, Hydraulic Couplings and the additional stress of the hydraulic connection to the shaft is small compared with the key connection.

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, 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, Hydraulic Couplings 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, the need to add another hydraulic coupling and its internal oil, if the use of hydraulic coupling, Hydraulic Couplings the earth can reduce the water hammer (or hydraulic pump) coupling cold oil equipment, such as the more complex

The hydraulic coupling, including the inner sleeve and the jacket of the coaxial bushing, and the inner circumference of the inner sleeve is conical, and an oil groove is arranged on the inner cone of the coat, and the outer round surface of the jacket is provided with an oil port connected with the oil trough through the coat wall. Hydraulic Couplings An inner thread is arranged inside the oil port, wherein the countersunk head screw is installed in the oil port of the inner thread, and the top part of the countersunk head plug is fitted with a sealing ring, Hydraulic Couplings wherein the outer end face of the sealing ring is located in the oil mouth. Effectively prevent the use of the process due to high-speed rotation of the shaft and the phenomenon of the countersunk head plug, in the deep sea use, but also to prevent the sea water along the oil port inside the threaded hole into the coupling inside, play the role of sealing, security hidden trouble, improve reliability.
