| Music | Hydraulic cylinders are commonly found in industrial machines. Consisting of an actuator, it uses hydrostatic energy to generate force. Hydraulic cylinders essentially use fluid to create a pull or push force. Because they contain fluid, however, they require the use of seals. There are hydraulic seals found in most hydraulic cylinders. What are hydraulic seals exactly? Overview of Hydraulic Seals Hydraulic seals are gasket-like rings that are designed to seal areas between the components in a hydraulic cylinder. Hydraulic cylinders contain many different components, some of which are exposed to the fluid. To prevent fluid from leaking around these components, hydraulic seals are used. Hydraulic seals are designed to fit the components in a hydraulic cylinder while creating a leak-proof seal around them. Hydraulic seals are essentially o-rings. However, they feature a groove within the lip that allows them to fit the components with which they are used. The groove will slide over the component to create a leak-proof seal. Even when the hydraulic cylinder’s piston moves and its fluid pressurizes, the component won’t leak. The hydraulic seal will keep the fluid within the appropriate container so that it doesn’t leak around the component. Hydraulic Seal Materials You can find hydraulic seals available in several materials. Rubber is a common material used for hydraulic seals. Rubber hydraulic seals are elastic, resistant to cracking, and long-lasting. There are also polyurethane hydraulic seals. Polyurethane hydraulic seals feature many of the same qualities as those made of rubber, but they are typically stronger and better protected against wear. While not as common as rubber or polyurethane, some hydraulic seals are made of polytetrafluoroethylene (PTFE). PTFE is a synthetic material that’s flexible, strong and resistant to extreme temperatures. Composite Centrifugal Pump Wear Rings Pump Composite Wear Ring Key Features Pump wear rings are simple components, but they have a profound impact on pump reliability, efficiency, and safety. Most centrifugal pump designs include replaceable rotating wear rings on the impeller (impeller wear rings) and stationary wear rings inside the casing (case wear rings). The wear rings in a pump serve three key purposes: Create the contact area between rotating and stationary parts inside the pump Reduce internal recirculation from pump discharge to pump suction or between stages Create hydraulic forces which stabilize the pump rotor The wear ring running clearance impacts pump discharge pressure, flow, efficiency, power consumption, vibration, and cavitation. Using composite wear rings with reduced clearance has a positive impact on all these factors. Composite Centrifugal Pump Wear Ring Advantages Long-term, large-scale field studies have shown that composite materials can improve pump life by up to 100%, reduce vibrations, and reduce seal leaks. Field tests and pump test stands have shown that reduce clearance can improve pump efficiency anywhere from 2-5% for typical process pumps. Additional pump composite wear ring material benefits include: Eliminating the metal-to-metal contact points essentially eliminates the risk of galling or seizure The wear rings will not seize or gall during slow roll or alignment The pump will have a better tolerance of run-dry events and other process upsets, with a chance of surviving extended off-design conditions Lower vibration due to improved damping at the wear rings Fewer seal leaks due to reduced pump vibration and reduced shaft deflection due to tighter wear ring clearance Higher efficiency due to lower leakage losses across the wear rings |
