The variable adjustment principle of hydraulic variable pumps involves changing the displacement or output flow of the pump to meet the changing requirements of the hydraulic system. By adjusting the displacement of the pump, the pump can deliver different flow and pressure levels for precise control and efficient operation. The following is a brief introduction to the principle and application of hydraulic variable pump variable adjustment: in principle: 1. Variable displacement: The hydraulic variable displacement pump is designed with a mechanism that can adjust the displacement of the pump. Displacement is the volume of fluid displaced per revolution of the pump's piston or gear. 2. Control Mechanism: Variable adjustment is achieved through a control mechanism, which can include features such as swash plates, tilting pistons, or variable displacement mechanisms. These mechanisms vary the stroke length, angle, or effective working volume of the pump to vary the flow output. 3. Flow adjustment: By changing the displacement of the pump, the flow delivered to the hydraulic system can be adjusted. This allows precise control of actuator speed, force and other parameters to meet the specific needs of the application. 90R250-KA-5-CD-80-S-3-C8-K-04-NNN-42-42-24 90R250KA5CD80S3C8K04NNN424224 90-R-250-KA-5-CD-80-S-3-C8-K-04-NNN-42-42-24 90R250KA5CD80S3C8K04NNN424224 90R250-KA-5-CD-80-S-3-C8-K-05-NNN-38-38-24 90R250KA5CD80S3C8K05NNN383824 90-R-250-KA-5-CD-80-S-3-C8-K-05-NNN-38-38-24 90R250KA5CD80S3C8K05NNN383824 90R250-KA-5-CD-80-S-3-F1-J-03-NNN-42-42-24 90R250KA5CD80S3F1J03NNN424224 90-R-250-KA-5-CD-80-S-3-F1-J-03-NNN-42-42-24 90R250KA5CD80S3F1J03NNN424224 90R250-KA-5-CD-80-S-3-F1-J-09-NNN-40-40-30 90R250KA5CD80S3F1J09NNN404030 90-R-250-KA-5-CD-80-S-3-F1-J-09-NNN-40-40-30 90R250KA5CD80S3F1J09NNN404030 90-R-250-KA-5-CD-80-S-4-C8-K-02-NNN-42-42-24 90R250KA5CD80S4C8K02NNN424224 90R250-KA-5-CD-80-S-4-C8-K-03-NNN-23-23-24 90R250KA5CD80S4C8K03NNN232324 90-R-250-KA-5-CD-80-S-4-C8-K-03-NNN-23-23-24 90R250KA5CD80S4C8K03NNN232324 90R250-KA-5-CD-80-S-4-C8-K-03-NNN-42-42-24 90R250KA5CD80S4C8K03NNN424224 90-R-250-KA-5-CD-80-S-4-C8-K-03-NNN-42-42-24 90R250KA5CD80S4C8K03NNN424224 90R250-KA-5-CD-80-S-4-C8-K-04-NNN-42-42-24 90R250KA5CD80S4C8K04NNN424224 90-R-250-KA-5-CD-80-S-4-C8-K-04-NNN-42-42-24 90R250KA5CD80S4C8K04NNN424224 90R250-KA-5-CD-80-S-4-C8-K-05-NNN-35-35-28 90R250KA5CD80S4C8K05NNN353528 90-R-250-KA-5-CD-80-S-4-C8-K-05-NNN-35-35-28 90R250KA5CD80S4C8K05NNN353528 90R250-KA-5-CD-80-S-4-F1-J-03-NNN-38-38-24 90R250KA5CD80S4F1J03NNN383824 90-R-250-KA-5-CD-80-S-4-F1-J-03-NNN-38-38-24 90R250KA5CD80S4F1J03NNN383824 90R250-KA-5-CD-80-S-4-F1-K-03-NNN-38-38-28 90R250KA5CD80S4F1K03NNN383828 4. Pressure adjustment: In addition to flow adjustment, variable adjustment can also realize the control of system pressure. By adjusting the displacement of the pump, the pressure generated by the pump can be adjusted to meet the requirements of the hydraulic circuit, providing sufficient force or power while avoiding excessive pressure that could cause damage to the system. 5. Control method: The variable adjustment of the hydraulic variable pump can be realized through different control methods. These methods include mechanical control, hydraulic control and electronic control. Mechanical control involves manually adjusting the displacement using a mechanical lever or knob. Hydraulic controls utilize hydraulic valves or actuators to regulate the displacement of the pump. Electronic control employs sensors, an electronic feedback system, and solenoid valves to automatically adjust pump displacement according to system demand. 6. Adjustment according to load: The variable adjustment of the hydraulic pump allows operation according to the load. The pump can automatically adjust the displacement according to the load requirements of the hydraulic system. As the load increases, the pump increases its displacement to provide higher flow and pressure. Conversely, when the load decreases, the pump reduces displacement to save energy and prevent overpressure. application: 1. Mobile machinery: Hydraulic variable displacement pumps are widely used in mobile machinery applications such as construction equipment, agricultural machinery, and material handling vehicles. These applications often require different flow and pressure levels to operate different hydraulic actuators, adjust vehicle speed or optimize energy efficiency. 2.
