Can hydraulic oil be used in the mechanical seal room?
1. It has certain mechanical and physical properties, such as tensile strength, tensile strength and elongation;2, a certain flexibility, hardness appropriate, and compression permanent deformation is small;3, and the working medium to adapt to, not easy to produce swelling, decomposition and hardening;4, wear-resistant, has a certain resistance to tearing;5, with high temperature, low temperature aging performance.
At present, most of the sealing materials used at home and abroad are polymer elastomers, and some of Jiashan Huanqiu mechanical seals factory also use plastic and various metals under special conditions. But no matter which material belongs to, it should have the following properties:
Influence of hydraulic oil on seal and its using methodThe hydraulic oil is used as the working medium of hydraulic system, energy transfer, conversion and control effect, but also has the various parts of the hydraulic system lubrication, corrosion, rust and mechanical seal cooling effect. The seals in the hydraulic system prevent leakage of fluid from the joint surface, maintain pressure, and maintain energy transmission or conversion.
However, there is no sealing materials including all of the above properties, according to the working environment, such as temperature, pressure, medium and movement way to select suitable sealing material, and through the formulation of materials to meet certain requirements. Or use two or more materials, composite or composite structure in the form of their own special skills, to achieve more comprehensive results.Sealing effect formation: dynamic seal is divided into non contact sealing and contact sealing. Non contact seal is the main variety of mechanical seals, such as graphite packing ring, floating ring seal; rubber composite seals and rubber seals belong to contact seal, by loading pre pressing force in the sealing cavity, blocking leakage channel and sealing effect. Seals used in hydraulic systems are mostly static seals (end face seals), reciprocating seals (pistons, piston rod seals) and rotary seals.
