Further, above-mentioned Oil pump electrical machinery assembly comprises side by side oil-pressing pump electric machine assembly in the high pressure oil pump electric machine assembly installed and at least one group, the output circuit of described high pressure oil pump electric machine assembly and in the output circuit of oil-pressing pump electric machine assembly be connected with the interflow control unit that is provided with total output circuit; Oil-pressing pump electric machine assembly top during above-mentioned fuel tank is installed in.
Maintenance for convenience, above-mentioned in each the oil-pressing pump electric machine assembly on the input oil circuit that is connected with fuel tank, be provided with the self sealing oil purifier, this self sealing oil purifier is used for cutting off when maintenance imports oil circuit.
Pressure regulation for convenience, above-mentioned in each the output circuit of oil-pressing pump electric machine assembly be provided with independent pressure regulation assembly.
As preferably, the utility model comprises oil-pressing pump electric machine assembly in two groups.
As further preferred, the utility model comprises oil-pressing pump electric machine assembly in three groups.
Hydraulic power unit described in the utility model adopts the fuel tank design of up-set type, compact structure, it had both had, and side putting type fuel tank hydraulic power unit vibrations degree is little, the advantage of stable working, have the underneath type fuel tank hydraulic power unit little advantage that takes up room again, and owing to put on the fuel tank, for the oil suction of oil pump is provided convenience, because the effect of gravity, need not increase under the compressed-air actuated situation on the fuel tank, easily oil suction of oil pump alleviates the oil pump bearing power.The utility model also is provided with the self sealing oil purifier on the input oil circuit, this self sealing oil purifier is used for cutting off input oil circuit, convenient for maintaining when maintenance.
Description of drawings
Fig. 1 is a large-scale top petrol tank hydraulic power unit structural drawing described in the utility model.
Below come the utility model is further described by the drawings and specific embodiments:
Embodiment
As shown in Figure 1, large-scale top petrol tank hydraulic power unit described in the utility model is applied to inner chamber metal machine for extrusion molding, for inner chamber metal machine for extrusion molding provides big flow adjustable pressure pressure oil, for each actuator provides hydraulic power.
Be specially, large-scale top petrol tank hydraulic power unit described in the utility model comprises frame 1, Oil pump electrical machinery assembly 2 and fuel tank 3, described Oil pump electrical machinery assembly 2 is installed on the mountion plate of frame 1, and the supporting component of described fuel tank 3 by frame 1 is installed in Oil pump electrical machinery assembly 2 tops.
Further concrete, above-mentioned Oil pump electrical machinery assembly 2 comprises side by side oil-pressing pump electric machine assembly 22 in the high pressure oil pump electric machine assembly 21 installed and at least one group, as preferably, above-mentioned Oil pump electrical machinery assembly 2 comprises oil-pressing pump electric machine assembly 22 in two groups, and as preferred forms, above-mentioned Oil pump electrical machinery assembly 2 comprises oil-pressing pump electric machine assembly 22 in three groups.Further, the output circuit of the output circuit of above-mentioned high pressure oil pump electric machine assembly 21 and middle oil-pressing pump electric machine assembly 22 is connected with the interflow control unit 4 that is provided with total output circuit, for inner chamber metal machine for extrusion molding provides big flow pressure oil, above-mentioned in each oil-pressing pump electric machine assembly 22 be provided with independent control switch, opening or closing of oil-pressing pump electric machine assembly 22 in each be can control according to actual needs, thereby the adjusting and the control of flow reached; Further concrete, oil-pressing pump electric machine assembly 22 tops during above-mentioned fuel tank peace 3 is contained in.
