SNH three screw pump overview

● Overview: SNH three screw pump is designed and manufactured according to the national standard GB10887-89. Three-screw pump is a positive displacement pump, which is the use of screw meshing principle, relying on the rotation of the screw in the pump sleeve intermeshing, the medium is closed in the meshing chamber, along the screw axial continuous push to the discharge port uniform, Provide stable pressure on the system. Three screw pump for conveying a variety of non-corrosive oils and similar oils and lubricants. The viscosity of the liquid transport is generally 3.0 ~ 760mm2 / S (1.2 ~ 100 ° E), high viscosity medium can be transported by viscosity reduction after heating. The temperature is generally not more than 350 ℃. Insulation screw pump (insulation bitumen pump) is mainly used for conveying high viscosity and high temperature lubricating liquid. Commonly used in asphalt, heavy fuel oil, heavy gear oil and other media delivery. The heat carrier can be steam, hot oil and hot water and the cold carrier can be a gas or a liquid. This product is widely used in petroleum, chemical, metallurgy, machinery, electrical, chemical fiber, glass, highway and other industries. ● Advantages: (1) wide range of pressure and flow, the flow range of 0.2 ~ 600m3 / h maximum working pressure up to 6.3MPa; (2) the type and viscosity of liquid transport a wide range; (3) Low, so you can use a high speed; (4) good suction performance, with self-suction capacity; (5) continuous flow, low vibration, low noise; (6) compared with other rotary pumps, the incoming gas And dirt is not very sensitive; (7) solid structure, easy installation and maintenance; (8) SN three screw pump, self-priming; (9) due to the universal assembly of a variety of components of the structure can be used for horizontal, And vertical installation; (10) According to the needs of the media can also provide heating or cooling structure; ● Use and scope of use: In the ship for transport, booster, fuel injection and lubrication pumps and marine hydraulic pump. In the heating equipment used for fuel injection, fuel supply and delivery pump. Used in the machinery industry as hydraulic, lubrication and remote motor pumps. In the chemical petrochemical and food industry used as loading, conveying and liquid pumps. Three screw pump is widely used in petroleum, chemical fiber, metallurgy, machinery, electricity, machine tools, ships, glass, roads and other industries. Three-screw pump for conveying fuel oil, lubricating oil, hydraulic oil, crude oil, asphalt and other similar lubricating oil liquid. Three screw pump lubrication in the industrial field for the pump, the hydraulic system for hydraulic pumps, fuel systems for transmission and booster pump; in the oil system for delivery and refueling pump.
