Description
Technical field
The utility model relates to hydraulic machinery, and particularly a kind of hydraulic pressure that is used for the magnesium smelting is pressed the magnesium machine.
Background technique
In the magnesium smelting industry, need after smelt finishing the magnesium metal in the crystallizing tank is taken out, extraction device commonly used at present is that the pressure magnesium machine by special use extrudes the magnesium metal in the crystallizing tank.Press magnesium machine main structure to be made up of frame and rack-mounted hydraulic system, crystallizing tank is fixed on the worktable in the frame, the pressure head on the piston rod extrudes the magnesium metal in the crystallizing tank in the hydraulic system by being installed in.In above-mentioned hydraulic system, adopt an oil hydraulic pump to provide pressure usually for oil hydraulic cylinder.When adopting gear pump, working flow is big because gear pump has, working pressure and power are little, generally adopts the 7.5KW driven by motor, so just determined that the upper and lower round trip of whole hydraulic system is very fast, but working pressure is little.When adopting plunger pump, though plunger pump can provide bigger working pressure, but because its flow is little, cause in the working procedure upper and lower round trip slower, and power is bigger, generally, make the whole hydraulic system of pressing the magnesium machine always at high pressure operation like this, Security and inefficiency at 22KW.
Summary of the invention
The purpose of this utility model is to overcome existing defective of pressing the magnesium machine, provides that a kind of working pressure is big, high working efficiency, hydraulic pressure that plant capacity is little press the magnesium machine.
For achieving the above object, the technical solution of the utility model is: a kind of hydraulic pressure is pressed the magnesium machine, comprise rack-mounted hydraulic system, this hydraulic system comprises oil hydraulic pump, oil hydraulic cylinder and solenoid valve, it is characterized in that the oil hydraulic pump in the hydraulic system is made up of a gear pump and a plunger pump, gear pump and plunger delivery side of pump are connected with the interface I of three-position four-way valve by pipeline, the interface II of three-position four-way valve links to each other with return line, the interface III of three-position four-way valve, the interface IV respectively with oil hydraulic cylinder on advance, liquid outlet is connected, be separately installed with one-way valve on the export pipeline of gear pump and plunger pump, the outlet of one-way valve is connected with three-position four-way valve interface I.
On above-mentioned two one-way valves and the bye-pass that three-position four-way valve interface II links to each other, relief valve is installed all.
Above-mentioned three-position four-way valve is a solenoid valve.
The utility model has made full use of the gear pump high volume, the characteristics that plunger pump pressure is big, with plunger pump and two oil hydraulic pump reasonable combination of gear pump, two oil hydraulic pumps are worked simultaneously during work, pressure when utilizing plunger pump that pressure magnesium is provided, utilize gear pump that reciprocal required flow fast is provided up and down, under the same like this working pressure, the plant capacity of technical solutions of the utility model has only 5.5KW, compare with the gear pump 7.5KW of existing same throughput, reduced 2KW, compare with the plunger pump 22KW of existing same pressure, power has reduced 16.5KW, and working efficiency improves more than 1 times.By working every day 10 hours, annual work was calculated in 300 days, year economize on electricity 6000-49500KW.
In sum, the technical solution of the utility model has, and is rational in infrastructure, manufacturing efficiency is high, the characteristics of economize on electricity, is fit to very much the needs of magnesium smelting industry energy-saving and emission-reduction.
Description of drawings
Accompanying drawing 1 is the utility model fundamental diagram.
Embodiment
As shown in Figure 1, on the pipeline of left side plunger pump 4 outlets one-way valve 2 is installed, the outlet of this one-way valve is connected with two pipelines, wherein pipeline is connected with left side, lower end interface I on the three-position four-way valve 5, relief valve 3 is installed on another bye-pass, and the outlet of this relief valve links to each other with right side, lower end interface II on the three-position four-way valve 5 by pipeline.On the pipeline of gear pump 7 outlets on right side one-way valve 8 is installed, the outlet of this one-way valve is connected with two pipelines, wherein pipeline is connected with left side, lower end interface I on the three-position four-way valve 5, relief valve 10 is installed on another bye-pass, and the outlet of this relief valve links to each other with right side, lower end interface II on the three-position four-way valve 5 by pipeline.The outlet and the return line of two relief valves that link to each other with above-mentioned two oil hydraulic pumps.Two interface III, interface IV are connected with liquid inlet and outlet on the oil hydraulic cylinder 6 respectively about the upper end on the three-position four-way valve.On the pipeline of side plunger pump 4 outlet, pressure gauge 1 is installed, on the pipeline of gear pump 7 outlets on right side, pressure gauge 9 is installed.Three-position four-way valve is a solenoid valve.
During use, open two oil hydraulic pumps simultaneously, at first make three-position four-way valve be in position as shown in Figure 1, this moment, the crystallizing tank 11 with magnesium metal was placed on the worktable of pressing the magnesium machine fixing, then three-position four-way valve is got to right positions, two oil hydraulic pumps are given oil hydraulic cylinder 6 fuel feeding simultaneously about this moment, oil hydraulic cylinder is moved down fast, pressure head on being installed in hydraulic rod is with after magnesium metal in the crystallizing tank contacts, because the pressure that the left side plunger pump provides is big and the gear pump on right side, one-way valve 8 on the right side gear pump discharge pipeline can effectively stop the hydraulic oil in the plunger pump of left side to flow to the right, and being equivalent to when pressing magnesium like this provides pressure by the left side plunger pump.After having pressed, three-position four-way valve is got to leftward position, gives the oil hydraulic cylinder fuel feeding simultaneously by two oil hydraulic pumps, and oil hydraulic cylinder is upwards returned fast, finishes the one action circulation.
