1, Sealing ring material and pressure:
Sealing ring materials are also very sensitive to pressure, and there are significant differences in the working pressure that sealing rings made of different raw materials and types of sealing rings can accept. Therefore, there are pressure tests, acid and alkali resistance, and high temperature resistance in sealing ring products. In terms of skeleton sealing, the accepted pressure is relatively small. If it exceeds its accepted operating scale, it will not always lead to leakage and also reduce the service life of the sealing ring.
The existence of sealing rings is essentially for the purpose of maintaining and maintaining the normal operation of machinery and equipment. For example, in hydraulic cylinders, sealing rings can prevent mutual leakage and hinder the entry of external residues into the machinery and equipment, avoid environmental pollution related to hydraulic oil and conflicts with machine components, improve the service life of machinery and equipment, and reduce problems displayed in work.
The quality of a machine's sealing equipment is becoming a key overall goal in identifying the role of machine equipment. Following the trend of contemporary specialization, old and crude sealing methods will gradually be selected. Sealing equipment, as an annotation of industrial equipment, will increasingly occupy a crucial position.
2, Sealing ring material and mechanical movement rate:
The habitual working ability of sealing ring materials to the mechanical movement rate also varies to a certain extent. When the mechanical equipment rotates at a high speed, the sealing ring of the raw material will usually be ineffective, leading to leakage.
3, Sealing ring material and operating temperature:
The effect of temperature on sealing materials is very harmful, and neither too high nor too low is acceptable. Excessive temperature reduces the strength and stretchability of the sealing ring, while too low temperature can make the sealing ring brittle. Therefore, each type of sealing material often has its own habitual low and high temperature. Nowadays, most sealing ring materials are mixed with raw materials, so temperature control should be more precise.
4, Compatibility between sealing ring material and working substances:
Selecting sealing materials based on sealing substances is a crucial criterion, as sealing rings will immediately come into contact with the sealing substances. If there is no good compatibility between them, it will not only damage the sealing rings but also pollute the sealing substances in the environment. The raw material of the sealing ring must not be corroded or damaged by the sealing material, and undergo a series of situations such as exothermic reactions, which require careful consideration.
