Since 1978, the gear pump has been widely applied in the exit zone of the thermoplastic plastics. The most typical fields are plastic material, cast-film and blown film. At present, the gear pump has been the essential equipment in the actual production. As a result, a lot of manufacturers often pack the

Why is the gear pump so popular? There are a lot of factors. For example, it is of great help to increase the thruput and improve the quality. Meanwhile, it makes a great contribution to saving the raw material and reducing the energy consumption. To some degree, the payback time of the investment is shortened to six months. When this pump is applied into the processing of the rubber products, the above-mentioned merits will naturally occur in the field.
In order to learn the application of the gear pump in the rubber field more clearly, the following passage will introduce some basic knowledge of this pump in this field. What comes first is its basic structure. This pump is composed of two symmetrical axes. Every axis includes meshing gears and journal bearings. Besides, the whole pump is coated with the shell. The pumping is provided directly through the gears. As for the bearing, it determines the position of the Gear pump axis and at the same time supports the whole axis. The obvious feature of this pump widely used in the rubber field is its integrative design about the gear and axis. When the product's viscosity is relative high, the torque and shear load will become very large and thus the process will be influenced. With the help of this integrative design, the problem can be solved and the whole equipment can bear larger force.
Next, there are some special requirements for the gear pump in the production of the rubber. In this industry, this pump is often widely used in a lot of typical rubber compounds, such as butadiene rubber, nitrile rubber, neoprene, bunas and natural rubber. Owing to the features of these compounds, the pump has to face a great number of challenges in the production. Compared with the thermoplastic plastics, the processing temperature for these rubber compounds is quite low, but they still may suffer from burning or coking. Besides, they also have other burning questions, such as high viscosity, low lubrication and high abradability. In a word, the common gear pump can not satisfy the production requirements of these rubber compounds at all. Therefore, something about the gear pump should be redesigned. For instance, in order to control the temperature there is a coolant mechanism in the pump body and pump axis. The parts which are easily abraded should be coated with the special stiffened material.
