Screw pump classification: 1.LQ3G three screw insulation asphalt pump? Overview: Three-screw pump is a positive displacement pump, which is the use of screw meshing principle, relying on the rotation of the screw in the pump sleeve intermeshing, the medium is closed in the meshing chamber, along the screw axis continuous uniform push to the row Export, to provide stable pressure on the system. Three screw pump for a variety of non-corrosive oils and similar oils and lubricants. Fluid viscosity range of 3.0-760mm2 / s (1.2-100oE), high-viscosity media can be transported by viscosity reduction heating. Its temperature does not exceed 350 ℃. Features: Three screw pump is characterized by a simple structure, small pressure pulsation, flow stability, work balance and reliable, allowing high speed, low noise, high efficiency, long life, self-priming capability. Use and use of: Three screw pump is widely used in petroleum, chemical fiber, metallurgy, machinery, electricity, machine tools, ships, glass, roads and other industries. Three-screw pump lubrication in industrial areas for the pump, the hydraulic system for hydraulic pumps, fuel systems for transmission and booster pump in the oil system for delivery and refueling pump. Flow range 0.2-600m3 / h, the maximum working pressure up to 6.3MPa. 2.LQ3G three screw pump working principle and scope of use Three screw pump is screw-type displacement pump. In the triple-screw pump, due to the main screw and the driven screw on the spiral groove intermeshing and their three holes with the inner surface of the bushing to pump inlet and outlet to form a number of dynamic seal chamber, the dynamic seal Room will continue to move the liquid from the pump inlet to the pump outlet and step up the delivered liquid. Thus forming a continuous, smooth, axially moving pressure fluid. The liquid delivered by the three-screw pump is a lubricating liquid containing no solid particles, no corrosive oil and the like oil, the viscosity is 1.2-100oE (3.0-760cst), the high-viscosity liquid can also be transported by viscosity-reducing after heating, Temperature does not exceed 150oC. Three screw pump is widely used in machinery, petroleum, steel, power generation, chemical fiber, food, shipbuilding and other industries. Second, the three screw pump structure and performance characteristics 1, the structure is simple: the pump itself consists of only three screws, but there are a variety of structures, the general small flow, 0.2-6.5m3 / h pump body and bushing into a lying Type installation, shaft seal for the mechanical seal. Pump bushing above medium flow is fixed to the pump body as a separate part. Large flow pump made of double suction structure. Shaft according to the different media have a mechanical seal and packing seal two. The prime mover for marine pumps is AC marine motor. 2, long life: the main screw of the three screw pump is driven by a motor. The main, from the screw, between the screw and the bushing has a layer of film protection, due to pump mechanical friction is extremely small, semi-permanent life expectancy. 3, the liquid in the pump for axial uniform axial linear motion, so the pressure pulsation small, stable flow, low noise, due to the rotation part of the small inertia, the starting torque and vibration is small. 4, with high suction capacity. 5, in order to ensure the safety of pumps, motors and piping systems, medium-volume screw pumps are equipped with safety valves above, when the pressure exceeds the safety valve set pressure, high-pressure oil will return to the pump inlet. 3.LQ3G small flow three screw pump? First, the working principle and scope of use Three screw pump is a screw-type displacement pump.

Product Description Screw pump is a single screw pump, its main working parts are eccentric screw spiral (called the rotor) and the inner surface of the double helical screw bush (called stator). Its working principle When the motor drives the pump shaft to rotate, the screw rotates on its own axis on the one hand, and on the other hand it rolls along the inner surface of the bushing, thus forming a sealed chamber of the pump. For one revolution of the screw, the liquid in the sealed chamber is pushed forward one pitch. With the continuous drive of the screw, the liquid is pressed spirally from one seal chamber to the other and finally out of the pump body. Screw pump is a new type of liquid transport machinery, with a simple structure, safe and reliable work, easy maintenance, liquid connection, pressure stability and so on. The thick slurry pumps produced by our company are all made of stainless steel, the non-toxic and odorless rubber linings can be used for the metal parts contacting with the material, the working temperature can be over 120 ℃, the slurry can be used for conveying food and the viscosity is 1-1000000 centipoise, Granules or plastic block solution slurry, the suspension of the corrosive medium. Widely used in food, metallurgy, chemical and other industrial sectors. 5.G-type single screw pump (thick pump)? Product introduction Single screw pump is a new type of pump that operates according to the positive displacement principle. The main working parts are eccentric screw (rotor) and fixed bushings (stator). Due to the special geometrical beginnings of the two parts, a separate sealing cavity is formed, respectively. Medium by the axial uniform flow. Low internal flow rate, the volume remains unchanged. The pressure is stable and therefore will not vortex and agitate the product. Each stage of the pump output pressure 0.6Mpa, lift 60m (water), self-priming height generally above 3m. Because the stator is made of a variety of elastic materials, the pump can not handle the high-viscosity fluid delivery and the transportation of hard suspended particle media or fiber-containing media. Its flow and speed is proportional to the drive can be directly driven by the coupling, or the use of high-speed motor, V-belt, gearbox and other devices speed. The pump parts less, compact, small size, simple maintenance, the rotor and stator are consumables of the pump, the structure is simple, easy to assemble and disassemble.
