3GBW series three screw heat pump is a positive displacement pump with a significant advantage insulation kits, can be transported need insulation medium, simple structure, small size, which allows smooth and reliable high-speed, pressure pulsation, flow stability, low noise, high efficiency is the use of screw engagement principle, depend on the pump comprising a rotating screw engaged with each other, the transport medium enclosed within the engaging dirty, continuously uniform axially along the screw to the discharge outlet pushed, the system steady pressure. ?????? 3GBW three-screw heat pumping high viscosity and high temperature lubricating liquid, often as asphalt, heavy fuel oil, heavy gear oil, heavy diesel oil transport and as a heat pump. Now widely used in road construction bitumen storage and transportation. ?????? Three screw pump for conveying various non-corrosive oil and oil-like liquid, the viscosity transmission fluid is generally 3 0 ~ 760mm / s. High viscosity medium viscosity by heating after delivery, the temperature generally does not exceed 350 ℃. 30GB series three screw pump with steel made with two kinds of insulation and without insulation, we recommend using a high viscosity medium screw holding structure. Pump import and export orientation, under normal circumstances, in the direction shown right into the factory that is left out, such as users with special requirements can also be made left right out. ?????? Three screw pumps are widely used in petroleum, chemical, metallurgy, machinery, electric power, machine tools, shipbuilding, glass, roads and other industries. ?????? Three screw pump for conveying the fuel oil, lubricating oil, hydraulic oil, fuel oil, asphalt and other similar liquid lubricating oil. ?????? Sealing performance of the pump, mechanical seal, according to different media, mechanical seal friction member use of different materials, for high viscosity media. Selection of high mechanical strength, good wear resistance alloy material to ensure the sealing performance under high temperature.
