Embodiment Construction
[0037] Such as Figure 1~5 Among them, a rapid hydraulic system for scrap steel shearing, a plurality of oil pumps 3 are respectively connected to the first oil inlet 7 and the second oil inlet 8; this structure facilitates the control of hydraulic oil flow according to working conditions.
[0038]In a preferred solution, the plurality of oil pumps 3 are respectively connected to the motor 2, the motor 2 adopts a frequency conversion double extension shaft motor, and each double extension shaft motor is connected to two oil pumps. Based on this structure and dynamic configuration according to working conditions, energy consumption can be further saved.
[0039] The system of the present invention is conventionally used in the rapid hydraulic system of 800-ton scrap steel shears. When it is used in 1250-ton scrap steel shears, the size of the plug-in directional valve does not need to be changed, only two sets of oil pumps and motor units need to be added to meet the requiremen...
