The requirements for mechanical seals for kettles are generally divided into two parts: liquid seal (this issue focuses on analysis) and gas seal (that is, dry gas seal, which will be summarized later and pushed to everyone). Liquid seal is a mechanical seal designed for sealing liquid. In fact, the liquid film between seal faces is very small - equivalent to 20 parts per million

Five tips to solve the problem of water leakage of kettle mechanical seal manufacturers. The feature of mechanical seals is that they can be used for all kinds of equipment, especially equipment such as reactors and pumps. Because such equipment has high sealing requirements and can not enter impurities, so they are used more often. The problem of water leakage is really worrying. Water leakage causes poor sealing effect of sealing elements. This is a taboo for many people. following

Misuse of installation steps of kettle mechanical seal manufacturers 1. The greater the spring compression, the better the sealing effect is. In fact, too much spring compression can lead to rapid wear and instant burning of friction pairs; Excessive compression makes the spring lose the ability to adjust the end face of the moving ring, leading to seal failure. 2. The tighter the dynamic ring seal diagram is, the better. In fact, too tight the dynamic ring seal is harmful and useless. The first is to intensify the sealing ring and
