Ordinary mechanical seals generally used in pumps are mainly used to transport liquids, which can provide lubrication and cooling. However, if the liquid is liquefied gas, which is particularly easy to volatilize, or is simply pure gas, then the lubrication and cooling effect cannot be achieved.
If the ordinary mechanical seal is used in a rotating state, it will be a dry friction state, and the sealing surface and auxiliary sealing ring will quickly overheat and damage. In order to solve the problems caused by the above-mentioned ordinary mechanical seals, dry gas seals should be used.
Non-contact
Dry gas seal is a non-contact seal, so requires less frequent maintenance than mechanical seals.
Micron air film gap
When the machine is running, a 3-10 micron air film gap will be formed between the dynamic ring and the static ring sealing surface of the dry gas seal.
Environmental protection
Dry gas seal minimizes emissions and avoids contamination of process media, which is ideal for applications with strict environmental regulations.
Wide applicability
Dry gas seal is ideal for high-speed and high-pressure applications, widely used in the oil and gas industry, chemical processing, and pharmaceutical industries.
Durability
Zhaoqiang's dry gas seals require no liquid or additional magnets, have a simple and compact structure, and operate without friction. The non-contact gas film solves the wear and leakage problems associated with mechanical seals, while achieving cooling effects and long service life.
Customization
Zhaoqiang's dry gas seals can be customized with multiple tandem sealing stages to enhance sealing performance. A variety of sizes and mounting configurations are also available to meet the equipment needs of various industries.
In summary, as one of the professional dry gas seal manufacturers, Zhaoqiang's dry gas seals provide reliable, maintenance-free and environmentally friendly sealing, which is an ideal solution for high-speed rotating machinery.
