What is the function of hydraulic coupler?

The primary function of a hydraulic coupler is to connect and disconnect hydraulic lines quickly and securely, facilitating smooth and efficient fluid flow within the hydraulic system. Its key functions include:

  • Ensuring leak-proof connections
  • Maintaining hydraulic pressure
  • Allowing for quick and easy line changes

What are the two types of fluid coupling?

  • Constant-fill fluid coupling: This type of coupling maintains a constant level of fluid, providing a steady transmission of power and minimizing shock loads.
  • Variable-fill fluid coupling: This type allows for adjusting the amount of fluid within the coupling, enabling variable power transmission and smoother starts.

How do hydraulic quick couplers work?

Hydraulic quick couplers work by allowing for the swift connection and disconnection of hydraulic lines without the need for tools. The internal mechanism includes:

  • Locking balls or pins that secure the coupler halves together
  • Seals that prevent fluid leakage
  • A valve that opens and closes to allow or block fluid flow

How to select or customize the appropriate hydraulic coupling?

Selecting or customizing the appropriate hydraulic coupling requires consideration of several key parameters:

  • Pressure Rating: Ensure the coupling can handle the maximum pressure of the hydraulic system.
  • Flow Rate: Choose a coupling that matches the flow rate requirements to avoid bottlenecks.
  • Temperature Range: Consider the operating temperature range to select materials that can withstand the conditions.
  • Fluid Compatibility: Ensure the coupling materials are compatible with the hydraulic fluid used in the system.
  • Connection Type: Select the appropriate connection type (e.g., quick-connect, threaded) based on system requirements.
