As the screw is constant rotation, so the liquid effluent flow is uniform. Screw the advantages can be seen from the above-mentioned works, screw pump has the following advantages: 1) The wide range of pressure and flow. A pressure of about 3.4-340 kgf / cm 2, the flow rate of up to 18600cm3 / min; 2) the type and transport liquid broad viscosity range; 3) because of the lower inertia force rotating member within the pump, it is possible to use a high speed ; 4) Inhalation good performance, with self-absorption capacity; 5) a uniform continuous flow, vibration, low noise; 6) compared with other rotary pumps, gas and dirt to enter the less sensitive; 7) solid structure installation maintenance easy. Screw disadvantage is that the higher the screw machining and assembly requirements; pump performance liquid viscosity sensitive. Three, three screw / screw pump Product Overview structural features illustrate the advantages of three screw used to transport temperature ≤150 ℃, viscosity 3-760cSt, no solid particles, non-corrosive, lubricating performance media. Pressure range: 10Mpa; mainly used in fuel transport, hydraulic engineering, marine engineering, petrochemical and other industries. Three screw conveyor lubrication liquid media types: such as machine oil, lubricating oil, heavy oil, residual; low lubricity liquids: such as light diesel oil, heavy diesel oil, wax thin oil; viscous liquid: such as synthetic rubber and synthetic liquid glue, emulsion. Structural features three screw pump having a rotor hydraulically balanced, vibration, low noise; output stable, non-pulsating; high pressure, high efficiency; with a strong self-absorption capacity; parts designed using the versatility of the series, with a variety of installation; compact structure, small size, light weight, and can operate at higher speeds; minimal mechanical friction, wear light, long life. It needs to also provide heating or cooling structure according to the transmission medium. Media is linear continuous conveyor, without stirring, no pulse; vibration, low noise; high pressure, high efficiency; simple structure, easy disassembly; small size, light weight; wear light, long life. Commonly used mechanical seal. Pump through the claw-type coupling is driven by an electric motor. Overhang from the spindle end of the pump to see, for the clockwise rotation. Four, three screw / twin screw product line model specifications a, HSNH three screw ten advantages HSNH three screw Advantages: 1.HSNH three-screw pump cycle wide range of pressure and flow.

Since the parts common combination 9.HSNH series has a variety of structures can be used for horizontal, and vertical flange installation. 10. The transport medium according to HSNH three screw needs can provide heating or cooling structure. Two, HSNH three screw design principles HSNH three screw according to national standard GB10887-89 design and manufacturing. HSNH three screw rotor positive displacement pump, which is the use of screw engagement principle, rely on a rotating screw engaged with each other in the pump kit, the medium is conveyed in a closed cavity meshing continuously push uniform along the screw axis to the discharge outlet , the system provides a stable pressure. Three screw pump for conveying a variety of non-corrosive and lubricating oils and oil-like liquid. Transmission fluid viscosity range is generally 3.0 ~ 760mm2 / S (1.2 ~ 100 ° E), high-viscosity media by heating viscosity reduction after delivery. Its temperature is generally not more than 350 ℃.
