Since 1978, gear pumps have been widely used in the export area of thermoplastics. The most typical fields are plastic materials, cast film and blown film. At present, gear pumps have become indispensable equipment in actual production. Therefore, many manufacturers often package the gear pump and the single screw for sale.

Why are gear pumps so popular? There are many factors. For example, it helps a lot to improve throughput and improve quality. At the same time, it also makes a great contribution to saving raw materials and reducing energy consumption. To a certain extent, the payback period is shortened to six months. When the pump is used in the processing of rubber products, the above-mentioned advantages will naturally appear on site.

In order to have a clearer understanding of the application of industrial gear pumps in the rubber field, the following will introduce some basic knowledge of the pump in this field. The first is its basic structure. The pump consists of two axes of symmetry. Each shaft includes meshing gears and journal bearings. Additionally, the entire pump is coated with a casing. Pumping is provided directly through the gears. As for the bearing, it determines the position of the gear pump shaft while supporting the entire shaft. The pump is widely used in the field of rubber, and its distinctive feature is the integrated design of the gear shaft. When the viscosity of the product is high, the torque and shear loads can become large and affect the process. With this integrated design, the problem can be solved, and the whole device can withstand greater force.

Secondly, there are some special requirements for gear pumps in the production of rubber. In this industry, such pumps are frequently used for many typical rubber compounds such as butadiene, nitrile, neoprene, nitrile and natural rubber. Due to the properties of these compounds, pumps have to face a number of challenges in production. Compared to thermoplastics, these rubber compounds can be processed at considerably lower temperatures, but combustion or coking can still occur. In addition, they suffer from other combustion problems such as high viscosity, low lubricity and high wear resistance. In short, ordinary gear pumps simply cannot meet the production requirements of these compounds. So something about the gear pump should be redesigned. For example, to control the temperature, there is a coolant mechanism in the pump body and pump shaft. Parts prone to wear should be coated with special reinforcing materials. "
