How to select the right heavy duty Quick Connect Coupling for your applications ?
- 1. How to select the right heavy duty Quick Connect Coupling for your applications ?
- 2. Definition of a Quick Disconnect Coupling • A device that can facilitate the connection and disconnection of an attachment to a power source, without the use of toools, while maintaining system integrity. • Quick Disconnect Couplings are labor saving devices, which expedite the connection and disconnection of Hydraulic , Pneumatic and Fluid Transfer components and hoses. Single Shutoff Straight Through Double Shutoff
- 3. Selection factors for Quick Connect Couplings Quick Couplings are components of a fluid system and are thereby subject to all system forces. Mayor considerations: • • • • • • 3 Flow Pressure Air Inclusion/ Spillage Temperature Media Environment 12/2/2013 Titel presentatie
- 4. Flow • System flow rate is one of the most valuable pieces of information needed and yet it often misunderstood. When design considerations are being made for coupling size and internal valving, system designers should always strive to minimize pressure drop to avoid inefficiency in the system. 4 12/2/2013 Titel presentatie
- 5. Pressure • Pressure is the single most important factor in the development of QC. Pressure influences virtually all of the components in QC and the misapplication of a product to an improper pressure application can lead to design disastrous results. • There are 2 forms of pressure: Static pressure: - Static pressure is caused by fluid or gas at rest , a constant pressure. Dynamic pressure: - Dynamic pressure is caused by fluid or gas in motion, a fluctuating/ pulsating pressure. Therefore we always ask what kind of application you’re dealing with. 5 12/2/2013 Titel presentatie
- 6. Spillage • Spillage is defined as the small amount of fluid that is lost when a coupling is disconnected, not be confused with leakage. 6 12/2/2013 Titel presentatie
- 7. Air Inclusion • Air inclusion is defined as the small amount of air infiltration into a system when a coupling is connected. Here again this test only applies to couplings that seal at the interface before the valves are open. 7 12/2/2013 Titel presentatie
- 8. Temperature • The temperature can have a dramatic impact on the design of the product. This generally takes the form of material selection of the base metal and elastomers used to make the coupling. • The media compability chart on the next page shows the temperature range for available seal materials. 8 12/2/2013 Titel presentatie
- 10. Environment • In the context of a quick coupling, environmental factors not only refer to contamination issue but also the conditions in which the coupling is used. Factor Safety Sleeve Locks, Exhausting Couplers Appearance Chrome Plating, Zinc Dichromate Plating, Private Labelling Installation Bulkhead Grooves, Flanges, End Connections Corrosion 316 Stainless Steel, Hastalloy, 303 Stainless Steel Danger of pull away Breakaway sleeves Danger of mixing up hoses Color Coding, Keyed Connections Mulitple Hose Connections Manifolding ( Multi-plates) Non Rotation Spacial Dimpled Locking Systems Sleeve Operation 10 Features Manual Connection, Automatic Connection 12/2/2013 Titel presentatie
- 11. Conditions of certain death Rotation • A small rotation of a few degrees is no problem. 360 degrees or more can lead to a disfunctional coupling, due galling. Vibration • High vibration can lead to dangerous situations even in low pressure applications Contamination • To avoid the contamination of dust,sand etcetera use dust plugs and dust caps in disconnect condition. Side load • The couplings always has to be straight in line with the nipple, if not leakage can appaer. 11 12/2/2013 Titel presentatie
