Single screw pump work is the same outer surface of the rotor in the corresponding inner surface of the stator meshing to form a special contact line, so that the separation of the stator cavity, the contact line, said seal line. When the rotor rotates according to a certain track, the seal line moves axially, and the stator cavity also moves axially, that is, displacement of the volume. At this moment, the seal line disappears at one end and a new seal line is generated at the other end, Push the media from one end to the other.
Single-screw oil and gas pump due to the use of flexible rubber material of the stator, the rotor meshing with the need for a certain amount of interference, so that it produces a reliable seal. When the pump is working, the sealing line can effectively prevent the gas from passing, so as to achieve the purpose of conveying the gas. When the medium contains solid particles, if the solid particles are squeezed in the sealing line, the surface of the stator rubber is compressed due to the elastic effect of the rubber stator, The particles cross the seal line and the stator rubber rebounds back to its original shape so that the single screw pump can achieve the purpose of containing a trace amount of solid particles in the transport medium.
Single-screw oil and gas mixing pump is suitable for corrosive media, gas-bearing media, sediment-containing solid particulate media and high-viscosity media. Gas content of up to 95%, medium viscosity up to 50000mPa · S, with a solid content of up to 60%, allowing the solid particle diameter ≤ 3.5 ~ 32mm, flow and speed is proportional to the low speed low flow to maintain pressure stability, Has a good regulatory performance, easy to achieve automation and control.
Across the pond, you will find the Deutsches Institute fur Normung (DIN) flange specification, consisting of a variety of European styles which have been unified into one code for the purpose of commonality. Designation as a DIN Flange by the German Institute of Standardization assures the user of design quality the way an ASME flange would here in America. Although much less common than ANSI/ASME steel flanges in the United States, many of our international customers request flanges to these specifications for a variety of applications such as imported steel vessels, cargo ships, and other infrastructure which may consist of metric pipes/valves and European designed equipment.
The subset flanges under the DIN standard consist of the same style of flanges in the United States, including the most commonly used slip on flanges, weld neck, flanges, and blind flanges. Adapter flanges can be custom made to end user requirements for the mating of American flanges to international ones, however we find it is a much more common and easy solution to provide DIN flanges to mate to existing equipment.
The most common metric type flanges fall under the following categories:
DIN 2501 through 2503 for flat ring flanges
DIN 2512 through 2519 for alternate face flanges
DIN 2627 through 2633 for weld neck flanges
DIN 2641 through 2642 for lap joint flanges
DIN 2565 through 2569 for threaded/companion flanges
DIN 2527 for blind flanges
