The medium conveyed by high viscosity gear pumps has a high viscosity

Due to high viscosity gear pump; The viscosity of the conveyed medium is relatively high. In order to reduce flow resistance and improve the suction capacity of the pump, the medium is heated or insulated. Usually, electric heating elements are used to uniformly heat viscous liquids. If the temperature fluctuation is not significant and the high viscosity liquid being transported is prone to degradation, it is recommended to use fluid heating, especially for gear pumps with large displacement. Fluid heating is divided into internal and external structures. The so-called built-in type refers to the internal heat sleeve of the gear pump body or end cover, while the external type is connected to the pump body through bolts to clamp the heat sleeve together. Whether to introduce steam, thermal oil, or cooling water into the jacket depends on the specific conditions of the medium. Built in type is suitable for situations where high temperature uniformity is required for conveying liquids, or where uniform cooling of high-temperature liquids is required. When the electric heating method lacks flexibility or does not require high temperature control, an external structure can be used.
