Spiral seal Non-contact dynamic seal with thread to prevent liquid leakage, also known as thread seal. Usually, the thread is machined on the rotating shaft of the sealing portion, and the liquid leaking during operation is filled with the thread and the space contained in the casing to form a "liquid nut". The direction of the thread on the shaft causes the "liquid nut" to produce axial movement as the shaft rotates, causing the liquid to continuously return to the high pressure end. The spiral seal is suitable for applications where the viscosity of the liquid is large, the differential pressure is small, and the medium speed is used. Basically independent of the temperature limit of the liquid. Http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn
