Principles for the purchase of engineering machinery seals

Construction machinery is an indispensable type of large-scale mechanical products in the modern construction engineering industry. Many construction machinery are inseparable from various types of seal products in the manufacturing process, especially mechanical products dealing with liquids, then engineering machinery seals. What should I pay attention to when purchasing?

Engineering machinery seals purchase principle:

1. According to the working speed, it is determined to adopt rotary or static type, fluid dynamic pressure type or non-contact type;

2. According to the pressure of the sealed cavity, it is determined that the sealing structure adopts balanced or unbalanced type, single end or double end, etc.;

3, according to the effective space of the installation seal, determine the use of multiple springs or single spring or wave spring, built-in or external type;

4. According to the temperature and fluid properties, determine the friction pair and auxiliary sealing material, and correctly select the mechanical seal circulation protection system such as lubrication, flushing, heat preservation and cooling.

In short, in order to ensure the quality of mechanical products, Xiao Bian suggests that you should choose a regular company to purchase products to ensure product quality.
