Owing to having designed liquid feed valve, liquid discharging valve, reduction valve, pressure regulator valve and plunger pump, by the effect of reduction valve, the pressure decreased of liquid transport pipeline and improved flow, no longer only use high-pressure transfusion tube road, therefore realize topping up and carried out together with suppressing two processes, reduced energy consumption.
The utility model has designed, plunger pump is set to include plunger pump I, plunger pump II and plunger pump III, the input end port of plunger pump I is set to be communicated with liquid tank by liquid feed valve, the output terminal port of plunger pump I be set to successively by liquid discharging valve and reduction valve and pressure regulator valve input end port be communicated with, the input end port of plunger pump II is set to be communicated with liquid tank by liquid feed valve, the output terminal port of plunger pump II be set to by liquid discharging valve and pressure regulator valve input end port be communicated with, the input end port of plunger pump III is set to be communicated with liquid tank by liquid feed valve, the output terminal port of plunger pump III be set to successively by liquid discharging valve and reduction valve and pressure regulator valve input end port be communicated with.
The utility model has designed, and liquid feed valve and liquid discharging valve are set to one-way valve.
The utility model has designed, and plunger pump I, plunger pump II and plunger pump III are arranged in casing and on the end face of the upper end of casing and are provided with abat-vent.
In the technical program, having realized liquid feed valve, liquid discharging valve, reduction valve, pressure regulator valve and the plunger pump that topping up carries out together with suppressing two processes is important technical characteristics, in the technical field of Emulation Concentration in Coal Mine high-pressure service pump, there is novelty, creativeness and practicability.
Four, accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Five, embodiment
Fig. 1 is an embodiment of the present utility model, illustrates by reference to the accompanying drawings the present embodiment, includes liquid feed valve 1, liquid discharging valve 2, reduction valve 3, pressure regulator valve 4, plunger pump I 5, plunger pump II 6 and plunger pump III 7,
The input end port of plunger pump I 5 is set to be communicated with liquid tank by liquid feed valve 1, the output terminal port of plunger pump I 5 be set to successively by liquid discharging valve 2 and reduction valve 3 and pressure regulator valve 4 input end port be communicated with, the input end port of plunger pump II 6 is set to be communicated with liquid tank by liquid feed valve 1, the output terminal port of plunger pump II 6 be set to by liquid discharging valve 2 and pressure regulator valve 4 input end port be communicated with, the input end port of plunger pump III 7 is set to be communicated with liquid tank by liquid feed valve 1, the output terminal port of plunger pump III 7 be set to successively by liquid discharging valve 2 and reduction valve 3 and pressure regulator valve 4 input end port be communicated with.
In the present embodiment, liquid feed valve 1 and liquid discharging valve 2 are set to one-way valve.
In the present embodiment, plunger pump I 5, plunger pump II 6 and plunger pump III 7 are arranged in casing and on the end face of the upper end of casing and are provided with abat-vent.
When plunger pump I 5, plunger pump II 6 and plunger pump III 7 are under bent axle drives, while doing drawback movement, the volume of oil cylinder increases gradually, formed parital vacuum, liquid discharging valve 2 is in closed state, and under differential pressure action, liquid feed valve 1 is opened liquid and entered in fluid cylinder, when plunger pump I 5, plunger pump II 6 and plunger pump III 7 continuous movings arrive the backward position limit, imbibition process stops, and at this moment in clutch release slave cylinder, imbibition is maximum.Volume when plunger pump I 5, plunger pump II 6 and plunger pump III 7 are done process motion in fluid cylinder reduces gradually, liquid is squeezed, pressure increases, feed liquor 1 is closed, liquid discharging valve 2 is opened, liquid is discharged from liquid-discharging tube, and when plunger pump I 5, plunger pump II 6 and plunger pump III 7 reach process limit position, the volume of active chamber is minimum, and discharge opeing process is complete.Plunger pump I 5, plunger pump II 6 and plunger pump III 7 are under the drive of bent axle, again do drawback movement, due to plunger pump I 5, plunger pump II 6 and the continuous to-and-fro motion of plunger pump III 7, liquid sucking-discharging process just constantly hockets, so highly pressurised liquid is constantly exported.
The utlity model has lower feature:
1, owing to having designed liquid feed valve 1, liquid discharging valve 2, reduction valve 3, pressure regulator valve 4 and plunger pump, by the effect of reduction valve 3, the pressure decreased of liquid transport pipeline and improved flow, no longer only use high-pressure transfusion tube road, therefore realize topping up and carried out together with suppressing two processes, reduced energy consumption.
2, owing to having designed plunger pump I 5, plunger pump II 6 and plunger pump III 7, by two liquid transport pipelines, realize topping up process, by a liquid transport pipeline, realize and suppress process, improved fluid injection efficiency.
3, owing to having designed reduction valve 3, antihypertensive effect is good, and flow is large.
Also have other with realized the liquid feed valve 1 that topping up carries out together with suppressing two processes, liquid discharging valve 2, reduction valve 3, the technical characteristics that pressure regulator valve 4 and plunger pump connect is all one of embodiment of the present utility model, therefore in Emulation Concentration in Coal Mine high-pressure service pump technical field, every liquid feed valve 1 that includes, liquid discharging valve 2, reduction valve 3, pressure regulator valve 4 and plunger pump, the input end port of plunger pump is set to be communicated with liquid tank by liquid feed valve 1 and plunger delivery side of pump port is set to by liquid discharging valve 2 and reduction valve 3, be communicated with the input end port of pressure regulator valve 4 successively, the input end port of plunger pump is set to be communicated with liquid tank by liquid feed valve 1 and plunger delivery side of pump port is set to be communicated with the input end port of pressure regulator valve 4 by liquid discharging valve 2, by liquid feed valve 1, plunger pump, the liquid transport pipeline that liquid discharging valve 2 and reduction valve 3 forms is set to be at least the technology contents of two all in protection domain of the present utility model.
