Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0022] like figure 1 As shown, a front swing center nozzle load simulation friction loading device provided by the present invention includes a friction loading hydraulic system 1 and a friction loading mechanism 2 communicating with the friction loading hydraulic system 1 . The friction loading hydraulic system 1 provides hydraulic power for the friction loading mechanism 2 .
[0023] like figure 2 As shown, the friction loading hydraulic system 1 is composed of an oil source 101, an oil hose 102, an oil return hose 103, a high pressure ball valve 104, a low pressure ball valve 105, a high pressure filter 106, a proportional pressure reducing valve 107, a pressure gauge switch 108, a pressure gauge 109. Electromagnetic reversing valve 110 is formed. The oil outlet of the oil source 101 communicates with the input end of the high-pressure ...
