Our structure is simple. Moreover, the seal is easy to manufacture and assemble. One of its remarkable features is its good adaptability to the oscillation and eccentricity of the shaft. The cavity in which it is mounted is compact in size for easy processing. It perfectly overcomes the gap issue caused by the oscillation and rotation of the sealing system when the shaft rotates, and the lip of the oil seal can always be in close contact with the surface of the shaft.
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.
Scraper seals are also known as wiper seals. The scraper sealof DMS SEALS can effectively prevent various forms of contamination that cause a hydraulic system failure. It can be mounted on the outside of the piston rod seal of the hydraulic cylinder to protect the hydraulic cylinder from dirt, dust and moisture. It can well protect the hydraulic cylinder from environmental pollution and effectively prevent damage to the hydraulic cylinder parts, causing the system to malfunction. DMS offers a wide range of wiper seals for different hydraulic systems with different characteristics, specifications and combinations.
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.
