The pan plug seal is a sealing element composed of a sealing ring and a corrosion resistant spring. There are a variety of energy storage springs to choose from, and each spring has different characteristics to meet special requirements.
Pan-plug seal is also called spring energy storage seal ring. The appropriate elastic force of the spring plus the pressure of the system makes the sealing material deform and close to the sealed parts, so as to achieve a continuous sealing effect.
In 2022, a major EV manufacturer recalled 20,000 vehicles due to—you guessed it—failed sealing rings. Post-mortem analysis showed electrolyte leakage reduced battery life by 40%.
The seal ring can be divided into a plurality of types, wherein the seal ring is quite common to be a rubber seal ring and a metal seal ring, and the rubber seal ring is generally...
The R&D teams have the ability to design and develop seals for various of complicated working condition of sealing system. We have already passed the certification of ISO 9001 and IATF 16949.
As a professional manufacturer of pan-plug seals & spring energy storage rings, we have become the preferred partner of major manufacturers in the industry with many years of experience and excellent performance.
The pan plug seal can be made according to the AS568A standard O-ring groove (such as radial shaft seal, piston seal, axial face seal, etc.), completely replacing the general O-ring, or our company can provide a reasonable groove design.
Pan-plug seal is also called spring energy storage seal ring. The appropriate elastic force of the spring plus the pressure of the system makes the sealing material deform and close to the sealed parts, so as to achieve a
The rotating seal spring energy storage sealing ring is a pressure-assisted sealing device. Both the jacket and the energy storage spring have excellent corrosion resistance.
By reducing the dimension of the spring, an axisymmetric analysis model of the spring energy storage sealing group is established, and the influence of temperature and medium pressure on the sealing performance of the designed sealing group is analyzed.
The metal energy storage spring is installed inside the U-shaped jacket and provides the U-shaped lip compensation force, making the seal have permanent elasticity, thereby reducing the impact of changes in working pressure, temperature or medium form.
