For the purpose of joining hoses or hoses and fixed fittings, hydraulic couplings are parts that come into play. Connectors for hydraulic hoses are always intended to be rotatable, in addition to providing a reliable and secure connection. This is the factor that enables the utilization of moving actuators while they are subjected to high pressure in the first place.
Structure of hydraulic couplings
The flexible pieces are connected in a manner that is form-fitting through the use of the traditional connector for hydraulic hoses. Because of the design of the clutch side, the internal balls are loaded across the largest cross-sectional area of their respective surfaces. On the one hand, this guarantees a connection that is exceptionally sturdy and resistant to tearing. On the other hand, the capacity to rotate the connection is preserved. This is particularly crucial for all systems with moving actuators.
The hydraulic coupling is in two parts
It consists of the following elements:
- Stepped twisted, rigid plug part
- Internal valves
- Socket side with balls, spring, clamping ring and seal
Functionality of hydraulic couplings
The hydraulic coupling can either be engaged or disengaged on the socket side of the device. The operator does this by pulling the clamping ring back against the spring that is located inside the device. The inner balls become more relaxed as a result, and their resistance is decreased. In spite of this, the coupling is not completely destroyed because it is still of sufficient size. A manual process is used to detach the hoses.
When the internal valves are no longer subjected to any additional force, they quickly terminate the pressure that is being applied to the line. Since this is the case, the amount of oil that escapes is decreased to a minimum that is barely measurable. The balls are pushed back into position by the tension ring when the coupling is being performed. At this point, you are unable to move, but you are still able to turn it like you would in a ball bearing. The connection between the hoses is secure and unbreakable.
Areas of application for hydraulic couplings
Wherever actuators are responsible for making significant motions, hose connections for hydraulic lines are utilised. Most of the time, this is the situation that arises when multiple actuators are coupled in series. A multi-axis movement that alternates between radial and linear actuators is made possible as a result of this. The following are some examples of typical applications for hydraulic couplings:
- Attachments on tractors
- Hydraulic backhoes
- Handling machines
- Forklift
- Telehandler
- Truck cranes
Standard items include hoses that are equipped with hydraulic connections. Changing them out or replacing them is a simple process.In the event that they become porous, I would recommend that they be replaced. On the other hand, a hydraulic connection that is leaking can be repaired at a low cost by using a new sealing kit with the repairs.
