There are generally two forms of thread sealing on the chemical pump. One is a thread connection pad seal, and the other is the threaded sealing seal. Both are used for sealing occasions where small diameter thread connections are connected. The sealing part of the threaded electric septum pump is sealing, and the thread only plays a compressive effect.

There are generally two forms of thread sealing on the chemical pump. One is a thread connection pad seal, and the other is the threaded sealing seal. Both are used for sealing occasions where small diameter thread connections are connected. The sealing part of the thread connecting the pad is a pad, and the thread only plays the effect of pressure.

In addition to the performance of the sealing effect, the roughness of the sealing surface and the relative geometric position accuracy of the thread hole also have a great impact on the sealing effect. When the sealing pad is tightened, it not only withstands the pressure, but also is also torque, which causes the gasket to deform or even damage. Therefore, when the gasket is non -metal, it is generally only suitable for chemical pumps with low pressure. The metal is a metal and the pressure can reach more than 30MPa.

The filaments often used on the chemical pump are another type of thread sealing.

Due to the economy of wire blocking, the combination of threads alone cannot play a sealing role, and often uses raw tape, sealing, and other filling to fill the sealing gap of the thread. Its pressure depends on the manufacturing accuracy and material of the thread, which has nothing to do with the coordination form of wire blocking and threaded holes. The threaded holes and wire blocks use "cone conversa" or "column -to -cone" whether the sealing effect is the same, but the area is different.
