This paper studies a buffer overflow valve that is attached to a hydraulic rotary motor which could reduce high hydraulic impact when the hydraulic rotary motor starts, brakes or suddenly reverses. A rotary motor buffer overflow valve was modeled and simulated using a computer software, AMESim, and the relation of the buffer overflow valve to the hydraulic impact experienced by the motor was analyzed. The cushioning property of the buffer overflow valve of a rotary motor is verified by using an excavator. It is concluded that having a reasonable design of the buffer overflow valve’s maximum displacement for the buffer set and diameter size for the buffer damping hole, it can reduce the pressure impact experienced by the hydraulic rotary motor and improve its operating performance, which also improves the service life of the system or its hydraulic components.

Unsaturated Seepage

Lessening the leakage of surface water can reduce the waste of water resources and ground water pollution. To solve the problem that Mengxi River could not store water enduringly, geology investigation, theoretical analysis, experiment research, and numerical simulation analysis were carried out. Firstly, the seepage mathematical model was established based on unsaturated seepage theory; secondly, the experimental equipment for testing hydraulic conductivity of unsaturated soil was developed to obtain the curve of two-phase flow. The numerical simulation of leakage in natural conditions proves the previous inference and leakage mechanism of river. At last, the seepage control capacities of different impervious materials were compared by numerical simulations. According to the engineering actuality, the impervious material was selected. The impervious measure in this paper has been proved to be effectible by hydrogeological research today.
