Shipping method: By air, by sea, by express, multi-modal transport Sealing is divided into dynamic sealing and static sealing, static sealing is divided into: pad sealing, glue sealing, and contact sealing three categories. Dynamic seal can be divided into two categories: rotary seal and reciprocating seal. The sealing forms can be divided into two categories: static seal between relatively static joint surfaces and dynamic seal between relatively moving joint surfaces. 1. Static seal: according to the working pressure, static seal can be divided into medium and low pressure static seal and high pressure static seal. Medium and low pressure static seal commonly used soft material, gasket wide gasket seal, high pressure static seal with hard material, contact width is very narrow metal gasket. 2. Dynamic seal: According to whether the seal is in contact with the relative moving zero part, it can be divided into contact seal and non-contact seal. Generally speaking, the contact seal has good sealing performance, but is limited by friction and wear, and is suitable for occasions with low sealing surface line. In the contact seal according to the contact position of the seal can be divided into circular (radial) seal and end seal. End seal is also known as mechanical seal. Non - contact dynamic seal labyrinth seal and dynamic seal. The former is to use the throttling effect of the fluid between the gaps to limit leakage, leakage is large, usually used in the inter-stage sealing and other sealing; A less demanding occasion. The power seal has centrifugal seal, floating ring seal, spiral seal, etc., is to rely on the power component to produce inpressure head to offset the pressure difference between the two sides of the seal to overcome the leakage, it has a high seal, but the energy consumption is large, and it is difficult to obtain the high pressure head. Non-contact seal, because the sealing surface is not in direct contact, small starting power, long service life. If the design is reasonable, the leakage will not be too large. But this kind of seal is the use of the equilibrium state of fluid mechanics and work, if the operating conditions change, will cause a large amount of leakage fluctuation. And the market can not buy this kind of seals, basically have user design.
