DMS SEALS TECHNOLOGY CO.,LIMITED
DMS Seals - Hydraulic Seals and Oil Ring Seals Manufacturer & Supplier
The Professional Sealing Solution Supplier(O Ring Suppliers & Oil Seal Manufacturers).
After improvement, DMS SEALS adopts the sealing form of Glyd ring plus wear ring, and obtains good effect. The oil seal is mainly composed of two components, Tecon seal ring and O-ring. Glyd ring is a double-acting seal ring, and its working principle is to use the pressure matching effect of O-ring and Tecon seal ring, and the sealing effect depends on the special shape design of the whole set of oil seals. Characteristics of Glyd ring: small friction resistance, no creeping phenomenon. Both dynamic and static sealing effects are quite good. No sticking phenomenon. Good performance with and without lubrication. Simple groove structure and easy installation. High pressure resistance and strong adaptability to working conditions. In addition, the material of Glyd ring is a very wear-resistant Tecon material, and special additives are added to make it have good rigidity to keep the seal shape from deforming under harsh conditions. Tecon material is almost resistant to all chemicals except liquid alkali, potassium carbonate and halides. The life span is hardly affected by ozone conditions under sunlight exposure, and the water absorption rate is 0.01%. Tecon materials have extremely high compressive strength and hardness, good thermal conductivity, electrical insulation, and wear resistance, and can withstand high mechanical loads, working pressures, and movement speeds.
The main function of the wear ring is to provide precise guidance and absorb radial forces. At the same time, since the wear ring is made of reinforced polytetrafluoroethylene, it can prevent metal contact between sliding parts in the hydraulic cylinder. Compared with metal wear rings, non-metallic wear rings have many advantages: good wear resistance and avoid metal-to-metal contact. It can suppress mechanical vibrations and allow larger gaps due to the centering effect of the wear ring. Good dustproof effect can prevent the entry of external particles. Simple grooves, easy installation and low maintenance costs.
