Introduction
In the field of industrial and commercial liquid transportation, the vertical single-stage oil pump plays a key role with its unique vertical structure and the characteristics of single-stage single-suction centrifugal pump. The vertical single-stage oil pump is a single-stage single-suction centrifugal pump with vertical structure, which is mainly used to transport oil media, such as gasoline, kerosene, diesel oil and other petroleum products. Its service temperature ranges from-20 C to 120 C. The design characteristics of the vertical single-stage oil pump make the pump body material still have good toughness and cold brittleness resistance at 20 C, so as to prevent the components from being broken or deformed due to too low temperature, and at the same time, the seal can maintain good elasticity and sealing performance.At 120°C, the pump body and related components can withstand the thermal expansion pressure of oil products and the weakening influence of high temperature on the structural strength of materials, maintain a stable working state, and ensure the continuity and safety of oil transportation.
The models of vertical single-stage oil pumps include ISG, IRG and YG. These models are designed to be suitable for different working conditions according to different temperatures and media. For example, IRG type is suitable for pressurized circulating transportation of high-temperature hot water, and its impeller, pump body and other key components are made of high-temperature resistant materials, and the flow path of high-temperature hot water is optimized in hydraulic design, so that it can run stably in the high-temperature hot water circulating system; YG model is specially used for transporting petroleum products. The pump body and internal parts are made of materials with good oil resistance and chemical stability, and a special oil leakage prevention structure is adopted in the sealing design, which provides a strong equipment guarantee for the storage, transportation and application of petroleum products.
