The Professional Sealing Solution Supplier(O Ring Suppliers & Oil Seal Manufacturers).
DMS Seals Technology Co., Limited is a technology-based enterprise specializing in the production of seals, the development of sealing materials and sealing solutions for special working conditions. Are in the advanced level of the same industry. The company has long-term cooperation and technical exchanges with many universities and scientific research institutions at home and abroad, and has a number of invention patents and production processes. The R&D team has the ability to design and develop sealing systems for various complex working conditions. The company is currently one of the largest professional seal R&D and manufacturing enterprises in China, and has passed ISO9001 quality system certification and TS16949 quality system certification. The company has relatively mature technical reserves in solving special working conditions such as ultra-high temperature, ultra-high pressure, ultra-low temperature, and strong corrosion. The products are widely used in construction machinery, automobiles, automation equipment, petroleum, water conservancy, chemical industry, aerospace and other fields.
Advantages of mechanical seal relative to packing seal:
①Reliable sealing During long-term operation, the sealing state is very stable and the leakage is very small. According to rough statistics, the leakage is generally only 1/100 of the soft packing seal;
②Long service life can reach 1-2 years or longer in oil and water medium, and can reach more than half a year in chemical medium;
③Small frictional power consumption The frictional power of the mechanical seal is only 10% to 50% of that of the soft packing seal;
④ The shaft or sleeve is basically free from wear;
⑤The long maintenance cycle can automatically compensate after the end face is worn, and under normal circumstances, no frequent maintenance is required;
⑥ Good vibration resistance, insensitive to the vibration and deflection of the rotating shaft and the deflection of the shaft to the sealing chamber;
⑦ Wide range of application Mechanical seals can be used for low temperature, high temperature, vacuum, high pressure, different speeds, and various corrosive media and media containing abrasive particles.
The disadvantages of mechanical seals relative to packing seals are:
①Complicated structure, high requirements for manufacturing and processing;
②Installation and replacement are cumbersome, and workers are required to have a certain level of installation skills;
③ It is difficult to deal with accidental accidents;
④ High one-time investment.
