3GBW insulation three screw is a positive displacement pump, solid structure, easy installation and there (horizontal, vertical, flange, cartridge) easy maintenance, a significant advantage of simple structure, small size, allows for high speed stable, reliable, small pressure pulsation, flow stability, low noise, high efficiency, is the use of screw engagement principle, relying on a rotating screw engaged with each other in the pump kit, the medium is transported in a sealed engagement dirty, along the screw axis continuous uniform pushed to the outlet, the system provides a stable pressure. Insulation three screw for conveying a variety of non-corrosive oil and oil-like liquid, transmission fluid viscosity is generally 3 0 ~ 760mm / s. High viscosity media delivery via viscosity after heating, the temperature generally does not exceed 350 ℃. 30GB series three screw adopts cast steel, there are two kinds of thermal and non-thermal, recommend the use of high-viscosity media screw holding structure. Import and export orientation of the pump, in normal circumstances the direction shown right into the factory that is left out, if you have special requirements can also be made left right out. Three screw pump for conveying fuel oil, lubricating oil, hydraulic oil, heavy oil, bitumen and other similar liquid lubricating oil. The pump sealing performance, mechanical seal, according to different media, mechanical seal friction components use different materials, for high-viscosity media. Selection of high mechanical strength and good wear resistance carbide materials, ensure the sealing performance at high temperatures. Three screw pumps are widely used in petroleum, chemical, metallurgy, machinery, electric power, machine tools, shipbuilding, glass, roads and other industries. Botou day extension Pump Co., mainly produces gear pumps, rotor pump, stainless steel pumps, high viscosity pump, screw pump, heat pumps, marine pumps and other 15 series over 300 kinds of product specifications, complete specifications, wide application .
