What is the function of hydraulic coupler?

fluid coupling

  • Transmit Power: Hydraulic couplers facilitate the efficient transfer of hydraulic fluid, which powers the system.
  • Prevent Fluid Loss: They ensure a secure connection, preventing leakage and maintaining system pressure.
  • Enable Quick Disconnects: Hydraulic couplers allow for rapid connection and disconnection of hydraulic lines, minimizing downtime.

What are the two types of fluid coupling?

fluid coupling

  • Constant Fill Coupling: This type maintains a constant fluid level and is suitable for applications where consistent torque is required.
  • Variable Fill Coupling: These couplings allow for adjusting the fluid level, providing variable torque output, ideal for applications with fluctuating load requirements.

How do hydraulic quick couplers work?

  • Connection: When the male and female parts are aligned and pushed together, internal mechanisms lock them securely.
  • Sealing: O-rings or other sealing components ensure a leak-proof connection, maintaining hydraulic fluid integrity.
  • Disconnection: A simple push or pull action disengages the coupler, allowing for quick detachment.

How to select or customize the right hydraulic coupling
