A novel asymmetric pump is used to improve the efficiency of boom. The pump can realize throttle-less driving and efficient energy recovering. 82.7% of the boom potential energy could be recovered. The system can significantly improve the working performance. The energy efficiency of the boom system can be further improved.
Thus, the pressure loss of the system, Δ p, is about 1.1 MPa. By referring to the results, during boom cylinder extension process, the pump pressure tends to oscillate which is similar to the load sensing system.
During the boom lifting process, the pump is driven by the hydraulic accumulator and the servo motor. And the hydraulic energy stored in the accumulator and the electric energy are transferred to the potential energy of the working device. The energy conservation equations can be written as Eq. (18).
A simple way to reduce the energy consumption is using the flow regeneration technology. In this paper, when the boom cylinder extends, the inlet and outlet oil valves open fully to reduce throttling loss. And then the regeneration technology is used when the boom cylinder retracts.
Boom cylinder controlled by separate metering system. In Fig. 7, the system in which boom cylinder is controlled by an independent metering system driven by an inverter motor. An electrohydraulic axial piston variable displacement pump which the pressure and flow can be continuously tunable is used in this system.
Thus, it can be concluded that the boom cylinder driven by the accumulator and the servo motor through the asymmetric pump, has the virtues of low pollution, high efficiency, and economical performance. 4. Experimental investigations and results 4.1. Test system

The UTF-8 BOM is a sequence of bytes at the start of a text stream (0xEF, 0xBB, 0xBF) that allows the reader to more reliably guess a file as being encoded in UTF-8.. Normally, the BOM is used to signal the endianness of an encoding, but since endianness is irrelevant to UTF-8, the BOM is unnecessary.. According to the Unicode standard, the BOM for UTF-8 files …
