2. Structural Composition: High-temperature oil pumps are typically composed of the pump body, pump cover, inner and outer rotors, pump shaft, and shaft-end assembly seals. The main drive system consists of a set of intermeshed rotors, with the shaft-end seal utilizing a high-temperature-resistant return-type assembly seal. The shaft seal temperature is controlled through a water tank cooling method.

3. Principle of Operation: The high-temperature oil pump is a positive displacement pump that relies on the intermeshing of the main gear and the driven gear to change the working volume for transporting the medium. This design enables the high-temperature oil pump to operate stably in high-temperature environments while ensuring efficient transport.
