Product Description The PGI series gear pumps are a range of internal gear pumps known for their high - performance and reliability. Here is a detailed English introduction: Types and SizesThe PGI series includes models such as PGI100, PGI101, PGI102, and PGI103. The PGI100, PGI101, and PGI103 are medium - pressure pumps, available in sizes 2, 3, 5, and 6. The PGI102 is a high - pressure pump, available in sizes 2, 3, and 6. Performance Parameters- Displacement : For the PGI100 series, the displacement ranges from 5.4 cm3/rev to 25.2 cm3/rev. The PGI102 series has a wider displacement range, from 3.8 cm3/rev to 250 cm3/rev.- Pressure: The PGI100, PGI101, and PGI103 have a rated pressure of up to 250 bar and a maximum pressure of up to 320 bar. The PGI102 has a rated pressure of up to 330 bar and a maximum pressure of up to 350 bar.- Speed: All these models can reach a maximum speed of 4000 rpm.- Viscosity and Temperature Range : The pump series is suitable for fluids with a maximum viscosity of 2,000. The temperature range is - 20 to 100 °C for the fluid, - 40 to 80 °C for the ambient temperature, and - 40 to 120 °C for the maximum fluid temperature. Structural FeaturesThe PGI series gear pumps adopt an internal - gear - meshing structure. The internal gear and the external gear are precisely matched, and the tooth profile is specially designed to ensure efficient meshing during operation, effectively converting mechanical energy into hydraulic energy. The pump has a compact structure, which takes up little space and is convenient for installation in various equipment. Working PrincipleBased on the positive - displacement principle, when the motor drives the gear to rotate, a series of sealed volumes are formed between the tooth spaces of the gear and the pump body. As the gear rotates, these sealed volumes change continuously. In the suction stage, the sealed volume on the side where the gears disengage gradually increases, forming a negative pressure to suck the fluid into the pump. In the conveying stage, during the meshing process of the gears, the sealed volume gradually decreases, and the fluid is squeezed and conveyed to the discharge side. In the discharge stage, the sealed volume further decreases, and the fluid is discharged from the pump body into the system at a certain pressure. Features and Advantages- Low Noise and Vibration: Due to the reasonable design and excellent manufacturing process, the PGI series gear pumps have a very low noise level and low vibration, which is beneficial to the stable operation of the system and the improvement of the working environment.- High Efficiency: Through the optimized gear design and sealing structure, the pump has a high volumetric efficiency, which can reduce internal leakage, improve energy conversion efficiency, and save operating costs.The PGI series gear pumps are widely used in various industrial fields due to their excellent performance. Here is a detailed introduction to their application areas:- Hydraulic Systems: In some small - scale hydraulic systems, PGI series gear pumps can serve as a power source, providing stable pressure oil for hydraulic cylinders, hydraulic motors and other executive components to achieve various hydraulic actions, such as the lifting and clamping of machinery. They are also used in the hydraulic systems of construction machinery, machine tools, injection molding machines, etc., driving hydraulic components to complete various working cycles.- Lubrication Systems: PGI series gear pumps are used in the lubrication systems of industrial equipment, delivering lubricating oil to various parts that need lubrication, ensuring good lubrication between the components of the equipment, reducing wear, and improving the operating life and reliability of the equipment.- Fluid Conveying Systems: In some general fluid - conveying occasions, such as conveying cooling liquid and cleaning liquid, PGI series pumps can meet the requirements for flow and pressure, ensuring the normal conveying and circulation of fluids. They are applicable to industries such as petrochemical, food, and pharmaceuticals, and can convey Newtonian or non - Newtonian liquids, ranging from light, volatile liquids to heavy, viscous, and even semi - solid liquids.- Industrial Cleaning Systems: These pumps are used in industrial cleaning equipment to convey cleaning liquid for cleaning various workpieces.- Fuel Systems: In some fuel - supply systems, PGI series gear pumps are used to convey fuel to ensure the normal fuel supply of engines. Their high - precision flow control and stability have an important impact on the performance and emissions of engines.- Renewable Energy Equipment: The PGI series gear pumps can be used in the hydraulic systems of wind turbines, such as the pitch - control hydraulic drive systems, which can accurately control the flow and reduce the risk of unplanned downtime through remote diagnosis.
