Precision measurement
The internal structure of the gear metering pump is scientific and advanced, and the processing technology is advanced. All parts in the pump are After precision grinding, its dimensional error is controlled to ensure that the internal gap value of the pump is minimized to improve volumetric efficiency, ensure the accuracy of the output flow, and reduce the impact of changes in external working conditions on its metering precision. Utilize metering pumps With high accuracy, various additives can be precisely measured and evenly injected into the corresponding chemical raw materials for the manufacture of final products. This application has been widely used in medicine, cosmetics, detergents, papermaking, petrochemicals , rubber and plastics, paint, polyurethane and other fine chemical and general chemical industries, and is also used in tobacco, brewing, beverage, food and other industries to measure various spices, vitamins, food pigments and other auxiliary materials to ensure product quality and control Production cost.
Coating process
Compared with various other metering pumps (piston pumps, diaphragm pumps), gear metering pumps have the characteristics of pulsation-free output and are especially suitable for coating processes. At present, gear metering pumps Metering pumps have been widely used to spray photosensitive emulsion in the production of photographic film, photo paper, printing plates and other products, and to spray magnetic slurry in the production of magnetic tapes, disks and cards, meeting the high-quality requirements of these products for the coating process. At the same time, this feature is also used in surface painting, such as in the automotive industry. The special gear metering pump can also have fast cleaning characteristics, which can meet the requirements for quick replacement of paint during the production process.
High-viscosity materials Measuring and conveying
The working principle of the gear pump
It is a closed gear space formed by a pair of mutually meshing gears and the pump body. The delivered materials are transferred from the inlet of the pump to the outlet of the pump, and at the outlet Through the meshing of the gears, the enclosed space becomes smaller, thereby allowing the material to be squeezed out of the pump body. Therefore, there is no one-way valve device in the gear pump. The characteristics of this structure make the gear pump most suitable for transporting metered high-viscosity fluids. It overcomes the pump efficiency problems caused by reciprocating pumps such as plungers and diaphragms due to adhesion and lax closing of the one-way valves when the material viscosity is high. The phenomenon of reducing, measuring inaccurately and even being unable to work. Gear metering pumps can be used in the production of hot melt adhesives, adhesives and polymer polymer products. In other industries, such as self-adhesive paper stickers, tapes, automobile windshield bonding, engine cylinder head seals, electronic components and It has also been widely used in the industrial production of rubber and plastic products.
