Insulation three screw pump is a positive displacement pump, the obvious advantages of simple structure, small size, allowing high speed smooth and reliable work, small pressure pulsation, flow stability, low noise, high efficiency, it is the use of screw meshing principle, relying on rotation Of the screw in the pump sleeve intermeshing, to be transported medium enclosed in the meshing dirty, along the axial direction of the screw pushed to the discharge port uniform and constant, to provide a stable system pressure. Three screw pump for conveying a variety of non-corrosive oils and similar liquids, the viscosity of liquid transport is generally 30 ~ 760mm / s. High viscosity medium can be transported by viscosity reduction after heating, the temperature is generally not more than 350 ℃. 3GBW series of three-screw insulation pump made of cast steel, with insulation and without insulation two, it is recommended to use high-viscosity insulation medium structure screw pump. Pump import and export direction, in the usual direction according to the direction of the factory that the right into the left, such as users have special requirements can be made into the left into the right out. 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, heavy oil, asphalt and other similar lubricating oil liquid. The pump sealing performance, the use of mechanical seal, according to the user of different media, mechanical seal friction member selection of different materials, for high viscosity medium. Selection of high mechanical strength, good wear resistance of cemented carbide materials to ensure high temperature sealing performance.
