Working principle: The hydraulic gear pump operates based on the principle of a positive displacement pump. The core components are gears and pump casing. When the gears rotate, the meshing clearance between them forms a closed volume space. As the gear rotates, the space gradually increases and decreases. When it increases, oil is sucked in, and when it decreases, oil is compressed and discharged, thereby achieving liquid transportation and pressure transmission.
Simple structure: composed of main components such as gears, pump casing, and shaft, the structure is relatively simple without complex components such as valves or pistons, resulting in high reliability and low maintenance costs.
High efficiency: Under low to medium pressure and high flow conditions, it can maintain high efficiency with minimal energy loss.
Strong adaptability: insensitive to oil pollution, able to adapt to harsh working environments, and capable of transporting oil with a certain viscosity.
Application scenario: In the industrial field, hydraulic systems are used for industrial equipment such as machine tools, injection molding machines, and die-casting machines to provide power and achieve various mechanical actions. Agricultural machinery, such as tractors, harvesters, etc., are powered by hydraulic gear pumps for their hydraulic systems, which are used to control the lifting, turning, and other actions of agricultural tools. Construction machinery is widely used in excavators,
