Will the temperature fluctuation of the Tin Pail affect the sealing performance?

1. Effect of thermal expansion and contraction
Material deformation: Temperature changes will cause thermal expansion and contraction of the Tin Pail and its seals. If the temperature fluctuation is too large, it may cause the seal to not fit tightly with the barrel, thus destroying the sealing performance.
Aging of seals: Frequent temperature changes will accelerate the aging of seals (such as rubber seals), reduce their elasticity, and thus affect the sealing performance.
2. Specific effects
High temperature effects: High temperature may cause the sealing material to deteriorate (such as burning, loss of elasticity, reduced hardness and strength), lubrication conditions to deteriorate (lubricating oil viscosity decreases, deteriorates or gels, oil film is burned), and the sealed parts to get stuck or the sealing gap increases due to thermal expansion or warping, causing sealing failure.
Low temperature effects: Low temperature may cause some sealing materials (such as plastics and rubber) to lose elasticity or crack, resulting in sealing failure.
3. Countermeasures
Control temperature fluctuations: Minimize the amplitude and frequency of temperature changes. It is generally recommended that the temperature change range should not exceed 10°C, and the cooling rate should not be greater than 1°C/min.
Choose the right material: Use high and low temperature resistant sealing materials, such as cold-resistant rubber seals or heat-resistant metal seals.
Check the seals regularly: Check the condition of the seals regularly and replace aging or damaged seals in time to ensure the sealing performance.
