Spring storage seal working principle

Date:Aug 26, 2019

The spring accumulator seal is composed of a polymeric material seal and a corrosion resistant stainless steel metal spring. The sealing ring is installed in the groove, the spring is pressed to form an outward tension, and the sealing lip is pressed against the sealing groove. Since the spring permanently provides the elastic force to the sealing lip, it can compensate for the wear of the sealing shell and the eccentricity of the fitting part, thereby forming Sealing from vacuum to low pressure. In addition, the system pressure assists the spring to store energy. The greater the pressure, the more the sealing lip fits the groove, thereby forming a high pressure seal.
