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.
It can maintain stable performance after prolonged exposure to various corrosive compounds. Due to its lack of polarity, low unsaturation, and high chemical stability, our gasket has high resistance to various polar chemicals such as alcohols, acids (acetic acid, hydrochloric acid, etc.), strong base (sodium hydroxide, oxidant, hydrogen peroxide), detergents, animal and vegetable oils, ketones and certain esters. It is designed to have excellent aging resistance and excellent resistance to compression set and compression stress relaxation. Therefore, our gasket has significant advantages over other conventional gaskets. Its excellent materials and manufacturing process enables it to achieve effective sealing when exposed to corrosive chemicals, friction, high temperatures or very low temperatures. At the same time, it is easy to install and has industry-leading creep resistance, which saves users a lot of time and cost and increases productivity.
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.
Influence of flange form: Different flange forms require different gaskets. Smooth-faced flanges are generally only used for low pressure, with soft thin gaskets; under high pressure, if the strength of the flange is sufficient, smooth-faced flanges can also be used, but thick soft gaskets should be used, or inner belt reinforcement should be used. Wound gasket for ring or reinforcement ring. In this case, metal gaskets are also not suitable, because the required pressing force is too large, resulting in large deformation of the bolts, making the flange difficult to seal. If a metal gasket is to be used, the smooth surface should be reduced to reduce the contact area with the gasket. In this way, under the condition of the same bolt tension, the compressive stress of the reduced narrow smooth surface will increase.
Construction machinery sealing system requirements: High and low temperature resistance Because of continuous work for a long time, if it is outdoors in summer, the hydraulic oil temperature of the machine may exceed 100°C, which requires the seal to be resistant to high temperature. If it is outdoors in winter, the temperature may be around -40°C when it is just turned on, and the seals are required to be resistant to low temperatures. Therefore, the sealing system is required to withstand a wide temperature range. The machine itself walks. Due to the limitation of volume and weight, the hydraulic oil tank is generally relatively small.
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 even more info on dmsseals.com.
