How to design an efficient hydraulic power unit? What are the optimization principles?

2025-04-28

The following principles should be followed in designing an efficient hydraulic power unit: Power matching - select the axial piston pump specifications according to the load curve to avoid "a big horse pulling a small cart". Energy efficiency - variable load systems use variable pumps or load-sensitive control to reduce throttling losses. Thermal balance - calculate the system heat generation, ensure heat dissipation capacity, and control the oil temperature within the optimal range of 30-60°C. Noise control - select low-noise pumps, install shock pads, and optimize pipeline layout to reduce turbulence. Reliability - consider redundant design for key systems, such as dual pumps or accumulator backup. Maintenance convenience - set up sufficient detection ports, components are arranged for easy access, and filters have blockage indications. Space efficiency - use integrated valve blocks to reduce piping, compact layout but retain maintenance space. Pollution control - reasonably set up the filtration system, and the oil tank design is conducive to impurity precipitation and gas separation. In addition, the system scalability must be considered, and 10-20% power margin and interface must be reserved.
