Embodiment 1
[0026] A machinery processing factory has 3 gravity casting equipment lines arranged side by side. Each production line has 16 gravity casting equipment, and each gravity casting equipment has an independent hydraulic station. The hydraulic station parameters of the gravity casting equipment in this factory are as follows :
[0027]
[0028] Among the 3 gravity casting equipment lines arranged side by side in this factory, the power consumption of No. 1 casting line is as shown in Table 1:
[0029]
[0030] Table 1
[0031] According to the data analysis in Table 1, the current power consumption of the hydraulic system of this equipment is about 11.66 degrees per hour.
[0032] The annual power consumption of the hydraulic systems of the 48 equipment of the 3 gravity casting equipment lines arranged side by side in this factory is shown in Table 2:
[0033]
[0034] Table 2
[0035] The solution of the present invention: the centralized pressure supply method of th...
Embodiment 2
[0069] The difference between Embodiment 2 and Embodiment 1 is that 30% of the maximum flow accumulation value, namely 1325cm3 / U, and 30% of the maximum pressure accumulation value, namely 5040bar, are taken as the rated flow value and rated pressure value of the new hydraulic station respectively.
Embodiment 3
[0071] The difference between the third embodiment and the second embodiment is that 25% of the accumulated maximum flow rate, namely 1104 cm3 / U, and 25% of the accumulated maximum pressure value, namely 4200 bar, are taken as the rated flow value and rated pressure value of the new hydraulic station respectively.
