Requirements of Rexroth piston pumps for internal combustion engines – Autosys Hydraulics

Thread Content

As we have learned earlier about the requirements of Rexroth piston pumps regarding the motors that drive them, what are then the requirements of Rexroth piston pumps for internal combustion engines? As we know, when a hydraulic pump is driven by an internal combustion engine, there are two scenarios: First: the hydraulic pump is merely part of the load driven by the internal combustion engine. When the hydraulic pump is just one component among the loads driven by the internal combustion engine, the power of the engine is sufficient to meet the power requirements of the hydraulic pump. The speed of the internal combustion engine should match the optimal speed of the hydraulic pump. High-speed internal combustion engines usually require a speed reduction mechanism to keep the hydraulic pump operating within its optimal speed range. 　　Second: All of the engine’s power is used to drive the hydraulic pump. A system in which all of the engine’s power is utilized to drive the hydraulic pump is called a fully hydraulic drive system. The fully hydraulic drive systems of mobile machinery typically use a volume control system with variable pumps or variable motors to meet the requirement for large speed variations in such machinery. The maximum speed of the internal combustion engine should meet the maximum flow rate required by the system, and shall not exceed the highest allowable speed of the hydraulic pump. If the speed of the internal combustion engine is too high, a speed reduction device should be installed. The maximum power of the internal combustion engine should be slightly greater than the maximum power required by the hydraulic system. 　　In the entire hydraulic system, the hydraulic pump is the power element, while the internal combustion engine or the electric motor that drives it serves as the source for converting power to that of the hydraulic pump. Therefore, the importance of the internal combustion engine or electric motor is self-evident; care must be taken to great extent when making choices regarding their combination in this context!
