LQ3G type three screw

■ LQ3G type three screw pump Product Overview: LQ3G type 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 transported in closed engagement cavity, along screw axis continuous uniform pushed to the discharge port, the system provides a stable pressure. LQ3G-type three-screw pumps for a variety of non-corrosive and lubricating oils and oil-like liquid. Transmission fluid viscosity range is usually 3.0-760mm2 / s (1.2-100oE), high-viscosity media can be transported through the heating viscosity reduction. Its temperature does not exceed 350 ℃. Flow range 0.2-600m3 / h, the maximum working pressure up to 6.3MPa. ■ LQ3G type three screw pump Model significance: ■ LQ3G type three screw pump Features: 1, the structure is simple: the pump itself composed of only three screws, but there are a variety of structural form, usually small flow, 0.2-6.5m3 / h Pump Pump body and liner combined into a horizontal installation, seal in mechanical seal. Medium flow as one or more separate pump liner part fixed to the pump body. High flow pump made more double suction structure. According to media delivery shaft sealing seal two different end mechanical and fillers. Marine pump prime mover for the exchange of marine motors. 2, long life: three screw main screw is driven by a motor. Lord, from between the screw between screw and bush Jie protection layer of film, due to mechanical friction pump is extremely small, life called semi-permanent. 3, the output of the liquid in the pump axial uniform motion, so the pressure pulsation, flow stability, low noise, small part due to the rotation inertia, the starting torque and low vibration. 4, with high suction capacity. 5, in order to ensure the pump, motor and pipeline system security, medium flow above the screw all with a safety valve, when the pressure exceeds the safety valve set pressure, high-pressure oil will flow back to the pump inlet. Figures 1 and 2 with a safety valve and two structural diagram without a safety valve.
