Metal springs, also known as energy storage springs, provide elasticity and compensation for sealing rings. Pan plug sealing spring can make the sealing element have permanent elasticity within the elastic range of the spring, and is less affected by working temperature, pressure, or process changes. The following figure shows two important characteristics of springs – load value and deformation range. Spring load affects the sealing force, friction, and wear rate of seals. The deformation range determines the ability of the plug seal to withstand wear and compensate for changes in groove size.
V-shaped spring is the most standard type of spring in plug seals and is widely used in various plug seals. The cross-section of the spring is V-shaped, which concentrates its load on the front edge of the sealing lip, providing a reliable wiping effect on the sealing element. V-shaped springs have a moderate load and a large deformation range, which can provide a larger compensation range and have a greater tolerance for shaft and hole run out and eccentricity.
O-shaped spring is a type of spring formed by spirally winding flat sheets, widely used in various plug seals. Due to the special design of the structure, it has a larger unit load and smaller deformation range than other types of springs. Therefore, it is most suitable for static or slow dynamic high-pressure sealing, and is very suitable for vacuum, gas, and low temperature situations, but has low tolerance for shaft and hole runout and eccentricity.
S-shaped spring is a spring formed by circular steel wire spiral winding. Due to its ability to provide almost constant spring preload and a wide range of size specifications, it is widely used in various plug seals and is easy to purchase.
N-type spring is a type of spring processed from circular steel wire into an inclined coil, which has a relatively constant load over a wide deformation range, allowing the seal to accurately control friction during its working life. Its unique design ensures that the seal does not damage the spring due to excessive deformation.
Because the types and specifications of Pan plug sealing spring may vary from manufacturer to manufacturer and industry standards, it is necessary to make comprehensive consideration according to the specific application scenarios and needs.It is recommended to consult a professional manufacturer or supplier when choosing for more accurate and detailed information.
To sum up, there are various types of Pan plug sealing spring, which can be selected according to different application scenarios and needs. The above information is for reference only, the specific type may change depending on the actual situation.
