What is a rotary seal? What are the advantages?
2021-09-16
Mechanical seals are indispensable in various industrial fields such as construction machinery, construction machinery, automotive equipment, etc. Rotating seals can withstand the two-way action of pressure or alternating pressure on both sides. At present, they have been widely used in rotating or oscillating rods, shafts, Pins, rotary joints, etc., and have been widely praised.

Do you know the characteristics of the piston rod seal?
2021-09-04
The piston rod sealing ring is a kind of sealing element, which can be divided into Gly ring and Ster seal. It is a symmetrical cross-section slip ring without filling material. The circular shape with elastic element and the sealing ring are combined to form a combined seal. The piston rod seal can also be used as a one-way seal.

Water pump seal leakage causes and treatment methods
2021-08-25
Water pump seal leakage reasons are as follows: 1. The reason for the excessive surface wear of the friction pair of the centrifugal pump mechanical seal is that the spring force is too large, the end face ratio is too high, the sealing medium is not clean, and the spring compression is too large. Centrifugal pump seal friction pair surface wear too fast processing method: replace the spring, add a filter, adjust the spring. 2. After the centrifugal pump is sealed, the machinery has vibration, heat, smoke, leakage, wear and other faults. The cause of the failure is usually the end face width is too large, the end face pressure is too large, the dynamic and static ring surface is rough, the friction pair is not properly matched, etc. Poor cooling effect, poor lubrication, end face

How to use the glace ring and stadt seal?
2021-08-10
The Glea ring is composed of a rubber ring and a polytetrafluoroethylene ring, and is made of polytetrafluoroethylene nitrile rubber. In special cases, the rubber elastomer nitrile rubber NBR uses fluorine rubber FKM, which can be divided into hole grid and shaft grid, but its sealing effect is the same. According to its own deformation, a higher initial contact stress is generated on the sealing surface, thereby preventing the leakage of pressureless liquid. When the hydraulic cylinder is working, the pressure liquid kneads the square sealing ring through the elastic deformation limit of the O-shaped sealing ring to make It fits closely with the sealing surface to generate a higher additional contact stress, which increases with the increase of pressure, and the initial contact stress is common

Polyurethane seals have good performance
2021-07-30
In daily processing or daily life, everyone will use different types of seals for daily sealing work. At the same time, due to some special environments, some seals cannot be used in some special environments. At this time, the relevant departments will use polyurethane seals for daily sealing work to achieve the usual sealing effect.

Characteristics of rotary seal
2021-06-15
The rotary seal is a dynamic seal. The rotary seal ring is composed of a slip ring filled with PTFE and a rubber O-ring that provides elasticity. It is used to seal the rod with rotating or oscillating motion. Shafts, pins, rotary joints, etc., have rotary hydraulic rotation in various industrial fields such as construction machinery, construction machinery, automotive equipment, etc. It is a two-way action and can withstand pressure on both sides or alternating pressure rotary seal.
