The spring seal produced by DMS SEALS is perfect for being applied to extremely high-speed, very low-speed equipment with micro piston strokes and other special operating conditions. It can be used with rotary seals and maintains good sealing performance in violent shake and vibration motion environments. At the same time, our seals are extremely adaptable to a wide range of working media. It is resistant to a wide range of chemicals except for soluble alkali metals, high-temperature fluorine and chlorine trifluoride. Therefore, it works well with liquids such as oils and water with high and low temperature.
It adopts the most ideal design and improved sealing performance and can minimize the high strength of local stress. This type of seal is designed to simplify installation and reduce particle generation. Moreover, it can be quickly and easily installed and removed to facilitate hardware assembly. It perfectly combines a custom seal design, proprietary bonding technology, and excellent plasma resistance developed for semiconductor applications. And its unique structure can minimize common installation problems.
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.
The selection principle of the gasket: according to the working pressure, working temperature, the corrosiveness of the sealing medium and the form of the sealing surface. Temperature influence: In normal temperature and low pressure, use non-metallic soft honey gasket; in medium pressure and high temperature, choose metal and non-metal combination gasket or metal gasket; when temperature and pressure fluctuate greatly, choose good elasticity or self-tightening type Gaskets; in low temperature, corrosive media or vacuum conditions, gaskets with special properties should be considered.
Key points of engineering mechanical seal design: Select a reasonable sealing scheme, focusing on the above requirements. First of all, the dustproof performance must be good. More than 80% of the failures of the hydraulic system are directly or indirectly derived from the stains in the system. Choose the best seals For seals of the same structure, the product quality of each company varies greatly. On the whole, the quality of large foreign seal companies is relatively stable, but the probability of encountering fakes is too high. Sometimes the so-called direct supply is not reliable. In terms of domestic seals, most of them are not very good, but at present, some manufacturers’ products have been chasing or even surpassing imported products, with stable and reliable quality, such as tetrafluoroethylene and rubber seals produced by Damson Sealing.
Support and positioning The piston and piston rod are radially supported and positioned in the cylinder barrel. Isolate the two pairs of motion pairs of piston and cylinder, piston rod and guide sleeve to prevent direct scratches, abrasions and strains between the motion pairs. Especially when the motion pairs are all steel parts, they must be isolated, otherwise they will be easily strained. The guide belt also has an important role to reduce the friction and friction work between the moving parts, reduce the ineffective work and heat. Vibration absorption and noise reduction Reduce system vibration and noise. It is mainly filled with tetrafluoroethylene and phenolic cloth, and there are also a very small amount of polyoxymethylene, nylon and soft metal.
