1. When selecting the process, the operating conditions must be considered. Here we can choose the appropriate sealing form, as well as its material and installation structure.
The working conditions that need to be considered for the selection of seals generally include: temperature, pressure, and medium. Other parts also need to consider the characteristics of the equipment itself, consider the choice of seals.
Regarding temperature, such as sealing materials, the operating temperature range of NBR materials is generally 40±120 degrees Celsius. That's over 120 degrees and you'll consider FKM or even Teflon. Low temperature is relatively rare. Generally speaking, when the temperature is 20~40 degrees, cold nitrile rubber should be considered. Generally, nitrile rubber materials will harden and cause leakage in low temperature environments.
For pressure, it affects the choice of sealing form. Generally speaking, low pressure and medium pressure rubber or PU seal will not be a big problem. But to consider the impact pressure, such as the start of the construction machinery, the impact pressure is much greater than the normal working pressure, frequent use of pressure up to 70Mpa collapse impact or clearance HByPGW make the main seal. PTFE composite seals are also a common choice.
The media issue is relatively simple. Special problems such as water, glycol and phosphate hydraulic oil are often used in the metallurgical industry. Although the working temperature is not high, but the choice of sealing module material or very careful, the latter uses the hydraulic oil, or choose FKM.
