Learn about hydraulic couplings

Hydraulic coupling is one of the types of coupling for efficient transmission. Specifically what type of coupling this is, how they work for heavy industry, let's find out in the article below for more information about this product!

The concept of "hydraulic coupling"

Hydraulic couplings play a role in helping the transmission to be carried out continuously and continuously by connecting the machine shaft with other details. In order for the system to operate without overload, the coupling also reduces the load on the engine and adjusts the speed appropriately.

Hydraulic couplings are also known as hydraulic couplings, hydraulic torque converters, hydraulic speed converters, and when they are used in the field of motor vehicles, they are called tor or torque converters.

It can be seen that this type of coupling uses some types of fluids such as oil, lubricant, mineral oil, etc. called hydraulic fluid to help it operate and act as transmission, unlike other types of joints. Air couplings use compressed air to operate.

In addition to other types of couplings such as inverter couplings, rigid couplings that also use a certain level of oil to operate, in industries such as metallurgy, mechanical engineering, electrical equipment manufacturing, enterprises, etc. will prioritize the use of hydraulic couplings.

Operating principle of hydraulic coupling

Different from the operating principle of traditional couplings, hydraulic couplings operate by hydraulic oil, so the connection of coupling type is soft. Hydraulic oil helps to transform torque so that power is transferred from the drive shaft to the driven shaft. Depending on the amount of liquid supplied, the device may or may not change the number of revolutions.

Hydraulic coupling is based on the following principle: When the device is powered, the motor drives the pump wheel inside the hydraulic coupling to rotate. Hydraulic oil will be pushed toward the turbine blades, causing the turbine to rotate and the machine to operate.

Detailed structure of hydraulic joints

The structure of the hydraulic coupling is quite simple, consisting of three main parts: the outer shell, turbine wheel and centrifugal wheel.

  • The outer shell is made of metal such as copper, stainless steel, plated steel, etc.
  • The turbine wheel connects the shaft to the hydraulic pump
  • The centrifugal wheel is responsible for closely connecting with the original motor shaft of the coupling.

All parts are made of metal so the durability of hydraulic joints is high, can withstand large loads, withstand impacts, and has a long life. Besides, they are also resistant to corrosion and can withstand changes in environmental temperature, so they can adapt to different working environments. The parts are connected together to form a fluid compartment such as oil, lubricant, mineral oil, etc. called hydraulic fluid.

Thanks to its tight structure, hydraulic couplings can operate effectively and help the engine and machinery operate at their best.
