LQ3G insulation three screw pump
The LQ3G type three-screw pump (also known as insulation type asphalt pump and high viscosity pump) produced by our company is designed and produced according to the national standard GB/T10886-2002. The pump is a positive displacement pump, which utilizes the screw meshing principle, and the rotating screw meshes with each other in the pump sleeve, and the medium to be conveyed is enclosed in the meshing cavity, and is continuously and uniformly pushed to the discharge port along the axial direction of the screw. Provides stable pressure.
■Flow rate: Q=2～600m3/h
■Pressure: H=0.1～6.3 Mpa
1) LQ3G type insulated three-screw pump can transport all kinds of non-corrosive oils and similar oils and lubricating liquids. The viscosity of the transport liquid is generally in the range of 3.0-760 mm 2 /s (1.2-100 oE). The high viscosity medium can be transported by heating and viscosity reduction. Its temperature does not exceed 350 ° C.
(2) The LQ3G thermal insulation screw pump (insulation type asphalt pump) produced by our company has the advantages of conveying high viscosity and high temperature lubricating liquid. It is commonly used for the transportation of medium such as asphalt heavy fuel oil and heavy gear oil. The heat carrier can be steam, hot oil and hot water, and the cold carrier can be a gas and a liquid.
(3) LQ3G thermal insulation three-screw pump also has medium continuous conveying, no stirring, no pulsation; low vibration, low noise; high pressure, high efficiency; simple structure, convenient disassembly and assembly; slight wear and long life.
