The rotary seal from DMS SEALS is a dynamic sealing component that is installed between the rotating shaft and the stationary parts to seal the lubricating oil and prevent external dust and debris from entering the inside of the device. When selecting the material, we fully consider the working medium, working temperature and the adaptability of the lip when the shaft rotates at high speed. It has a remarkable sealing performance and can maintain a great sealing effect for a long time.

The gasket made by DMS SEALS is uniquely mechanical and thermally stable and it has excellent oxidation resistance. Compared with other thermoplastics, it can be applied to components such as valves and bushings, with higher wear resistance, higher mechanical properties and thermal fatigue resistance. At the same time, it has excellent oil resistance (alkane oil), heat resistance, water resistance, aging resistance, air tightness and excellent adhesion. It is commonly used in media such as water, oil, and natural gas.

The rod seal is the most important sealing component designed by DMS SEALS in the liquid sealing application. It can effectively prevent the liquid inside the cylinder from leaking to the outside. Moreover, if there is a leakage problem in the rod seal, the performance of the equipment will be degraded. There are even some machine and human safety issues in extreme cases. This type of seal meets the standards of GB/T 15242.1-94 and GB/T 15242.3-94. It is ideal for high and low-speed reciprocating rods and rods in high-pressure system cylinders. Moreover, it can be used in a variety of fluids and high-temperature environments. It is characterized by its high corrosion resistance and its ability to work well in a corrosive media with no oil spots. It has high stability under pressure and harsh conditions. The outstanding advantages of our seals are strong wear resistance, resistance to extrusion, low friction and no stick-slip.

Destroy the leak: The working conditions of the sealing part are relatively bad, the thermal deformation is large, it is often subjected to vibration, impact, improper installation, excessive tightening force, repeated use, compression deformation, internal stress concentration, damage beyond the fatigue strength, material aging, deterioration, etc. will cause damage to leaks. This kind of leakage has the greatest impact and great harm, so it is necessary to strengthen prevention.

However, hydraulic transmission also has disadvantages compared with mechanical transmission: It is easy to leak and not friendly to the environment. High manufacturing precision is required. Low efficiency. The transmission ratio is not fixed. Due to the special working environment of construction machinery, its hydraulic system has the following characteristics: The working hours are irregular, and sometimes work continuously for a long time. The working environment is outdoors, the working temperature difference is large, and the working environment is dusty. The machine itself walks. Due to the limitation of volume and weight, the hydraulic oil tank is generally relatively small. Due to the volume and weight, the working pressure of the hydraulic system is high, usually above 20MPa, and the highest is about 40Mpa.

Supplied in rolls or open loops. The open ring can be directly installed and used, but it must be cut when the roll is used, and the cutting length must be calculated in advance: there can only be one opening, the opening form is an oblique 45° opening, and the opening distance is about 3-15mm, or the diameter of the guide ring 3-5% of . Under normal circumstances, the openings are oblique openings. Straight openings or zigzag openings are rare and have specific uses and purposes. There are two purposes for the opening. The first is to facilitate installation. If it is not opened, it is an integral ring, which is difficult to install or impossible to install, so it must be opened. Secondly, the opening and a certain opening distance are reserved to facilitate the automatic coordination of volume changes. Otherwise, the movement may be stuck or the moving parts may be pulled due to the excessive expansion of the guide belt under certain conditions. Coiled ones are relatively cheap, and the same coil can be used to make guide rings of different sizes. Find additional info at https://www.dmsseals.com/.
