Structure and Application Characteristics of Super High Pressure Seal of Piston in Hydraulic System
2020-07-01
With the development of industrial technology, people's requirements for reciprocating motion are gradually increasing. With the development of energy, mining, metallurgy, railway, highway and construction industries, high-pressure, high-speed, low-friction piston rod and rubber ring combined ultra-high-pressure sealing structure is often encountered, which is generally called "combined seal".

Principle and Characteristics of Rotary Sealing Ring for Shaft
2020-06-10
The rotary seal ring for shaft is not only used for hydraulic cylinder and its pneumatic sealing, but also for air intake system and rolling bearing anti-fouling. The rotary seal ring for rotary shaft can be divided into rotary skeleton seal, V-ring and Glea ring. Among them, Sinoe hydraulic sealing technology tells you that the rotating Glea ring used for the shaft is resistant to high temperature, acid and alkali, and has good compression resistance. The substance can dissolve gear oil, flame retardant liquid, water and gas. The main use in the work is generally portable hydraulic machinery and Its mechanical equipment, etc.

How to choose the right large size sealing accessories?
2020-05-18
From the point of view of environmental protection, large-size seals must not allow the oil, fuel, harmful liquids and gases and other fluid media inside the machine and system to leak to the surrounding environment. For some petroleum, chemical and atomic energy industries, the leakage rate of large-scale seals should be controlled below 10-7cm3/s. These indicators have been recognized by many countries in the world. However, the sealing of fluid is a complex and difficult problem to solve, the reliability of the seal is not only related to the sealing material and sealing element, but also related to the structure of the connection, the characteristics of the fluid medium, the working conditions and many other factors.

Common Problems of Rotating Sealing Ring
2020-03-12
Rotary seal ring is installed between the rotating shaft and stationary parts, used to seal the leakage of lubricating oil and prevent external dust and debris from invading the equipment. Also called rotating shaft lip seal, commonly known as oil seal. Rotary sealing ring can be divided into lip type sealing ring and reciprocating seal, the application is very wide, then, we will encounter in our daily work what kind of rotary sealing ring related sealing problems?

Working principle of rotary seal
2020-03-09
Rotary seal is a kind of dynamic seal. It is used to seal rods, shafts, pins, rotary joints, etc. that rotate or swing. It is composed of a slip ring filled with PTFE and a rubber O-ring that provides elastic force. It is a two-way rotary sealing ring that can withstand pressure on both sides or alternating pressure, rotary hydraulic rotation exists in various industrial fields such as construction machinery, construction machinery and automotive equipment.

Piston rod seals should be considered in the purchase of factors
2020-03-06
As we all know, the piston rod seal refers to the seal between the piston rod and the cylinder head to prevent fluid from leaking from the inside of the hydraulic cylinder to the outside. It is one of the most demanding applications in fluid power equipment. The leakage of the piston rod seal will affect the performance of the entire machine equipment. And life, while in severe cases, it will cause environmental problems. In order to meet the needs of the industry for practical sealing solutions, piston rod seals are required to act evenly on the sealing area, have good medium compatibility, high and low temperature resistance, wear resistance, anti-clearance extrusion, low friction, compact structure and Easy to install.
