The quick connect fittings, as the name suggests, can improve efficiency. How to choose the right connector?
When choosing the correct connector, the frequency of hose connections and disconnections is the main factor in the type of connector that should be used. For example, in a workstation where pneumatic tools are to be replaced multiple times during a shift, quick-connect couplers can quickly change tools and significantly increase productivity.
Another example is the hydraulic testing process. Quick couplings greatly reduce the time required to test each component. If technicians are required to use a wrench to connect and disconnect the system, every test process will take precious time. Similarly, the use of quick connectors can increase productivity.
Because of this, many industries are rapidly adopting quick couplings, so the increase in efficiency far exceeds the increased cost.
What is a quick connector?
Quick couplings, often called quick couplings, QD or quick-action couplings, are mechanical devices that provide a quick, easy, and reliable way to repeatedly connect and disconnect almost all fluid or gas lines. All quick connect connectors have two parts: plug and socket. The plug is male and the socket is female. When properly connected, these parts will effectively seal and lock the joint to withstand internal pressure and resist any tension that may pull the joint apart.
The most significant advantages of quick couplings over standard hydraulic connectors are:
Connection/disconnection time
Prevent liquid leakage
How to choose the right quick coupling. Why is the excavator quick coupling department reluctant to use the quick coupling?
Cost is a factor that prevents the more widespread use of quick connect couplings. These couplings contain more components, such as valves and locking mechanisms, which means higher material and assembly costs.
Secondly, there is the problem of pressure drop. The medium flowing through the internal valve causes turbulence of the medium (fluid or gas). Think about the impact of rocks on river flow. This may cause a slight drop in pressure, which can be called "pressure drop" (PSID).
Ball valves are usually matched with quick connectors. For example, the common two piece of ball valve. The two-piece ball valve is the most widely used ball valve. The end connection of the threaded ball valve allows quick and easy installation on pipe threads.
