The function of a hydraulic phenolic wear ring is to guide the shaft and hole sealing of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system
Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurised fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore.For a cylinder which is exclusively single-acting, capable of sealing dynamic pressure from one side (unidirectional), it is always best to choose the type of seal designed to provide optimum sealing qualities for single-acting functions.
HBY buffer ring does more then normal buffer ring does, not only just buffer the pressure spikes of hydraulic systems, but also acts as a primary seal and pressure spike suppressor. It is mainly used in construction machinery cylinder.
Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
The wiper seal is the most undervalued seal type in the hydraulic cylinder in relation to its important function. Particular attention should be drawn to its selection, the surrounding environment and service conditions must also be taken into special consideration..
The rod seal is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues.
Back-up rings are also known as anti extrusion rings. They have been used for many years in conjunction with O-Rings in high pressure applications. A back-up ring is a rigid ring that holds an elastomeric seal to its designed shape and in its correct place. Back-up rings are often used with O-Rings to prevent extrusion at high pressures.
PTFE piston seals Glyd Rings (BSF) works perfectly as double acting Piston seals of hydraulic components such as injection molding machines, machine tools, presses, excavators, forklifts & handling machinery, agriculture equipment, valves for hydraulic & pneumatic circuits and so on.
The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure..
For over 20 years,DLSEALS has specialized in the development and production of sealing systems which were used in the Metallurgical,Electrical,Auto, Engineering machinery, Light industrial machinery and Electrical appliance manufacturing industries.
