Introduction to the application and principle of supercharged fuel pump

Supercharged fuel pump booster jet combustion and heavy oil, specially designed in the process of coal tar deep processing, suitable for high temperature resistance <200 °C> strong anti-impurity, stable pressure, long holding time, etc. According to the characteristics of the quality, the main components of the structure and the shaft end seal have been improved accordingly, which makes the pump more suitable for a specific medium, and the service life is more than twice that of the same general gear pump. It adopts self-sealing lubrication, the gap automatically adjusts the structure, and the parts are made of high wear-resistant materials. It has the characteristics of compact structure, good self-priming, high efficiency, strong adaptability, etc., in the case of conveying liquid containing impurities, the working life of the residual oil pump It is 3-5 times longer than the general gear pump. The design of this type of pump fully considers the interchangeability with the ordinary gear pump. It also shows the important characteristics of long life and stable pressure of the pump when conveying the medium with lubrication and no impurities.
This type of pump is suitable for heavy oil, diesel oil, coal tar, grain and oil, chemical industry with conveying temperature not higher than 200 °C and viscosity not more than 150mm2/S containing non-metallic impurities. The high-pressure fuel gear pump is improved on the basis of the original ZYB type residual oil pump. The main parts are made of more high-quality wear-resistant materials, which have high strength and hardness after heat treatment. A number of original hydraulic balance technologies are adopted in the structure. The pump has high efficiency, low noise, stable operation and long holding time.
The supercharged fuel pump is provided with an adjustable structure of the gear end gap. When the working pressure drops when the pump works for a certain period of time, the gap of the end face of the pump can be adjusted by the external fine adjustment structure on the pump cover, so that the working pressure of the pump is obtained. Recovery, and can be adjusted several times. Therefore, it is 5-10 times longer than the service life of general gear pumps. It is the first in China's high-pressure injection of impurities containing combustion oil, and has reached the advanced level and building materials of similar products at home and abroad.
