Description
Technical field
The utility model relates to a kind of automatic controller, specifically YB hydraulic plunger slurry pump automatic controller.
Background technique
YB hydraulic plunger slurry pump is a kind of by hydraulic driving, carries and the equipment of the various slurry that pressurizes, the equipment use such as main supporting pressure filter.Pressure filter is a kind of filter plant by dewatering by extruding, is supported the use for slurry by slurry pump.Due to pressure filter in the course of the work, along with filter chamber material matter pile up, can diminish gradually to slurry demand.In order to improve dewatering efficiency, pressure also needs to increase at times; But YB slurry pump is due to outlet pressure and constant flow, effectively can not mate with pressure filter, so just largely cause energy loss, extend the operating time, reduce working efficiency.
Summary of the invention
The purpose of this utility model is to provide YB hydraulic plunger slurry pump automatic controller, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
YB hydraulic plunger slurry pump automatic controller, comprise variable piston oil pump, variable piston, PC valve, relief valve, proportional pressure control valve, electrical power amplifier, pressure transducer and PLC, described variable piston oil pump is provided with variable piston, described variable piston oil pump oil outlet is provided with relief valve, described PLC is connected to proportional pressure control valve by electrical power amplifier, PC valve is provided with between described proportional pressure control valve and variable piston oil pump, described PC valve is connected with variable piston oil pump, described variable piston oil pump oil outlet arranges pressure transducer, described pressure transducer and PLC electrical connection, hydraulicchange-over valve and rotary valve is provided with between described variable piston oil pump and oil cylinder, described hydraulicchange-over valve is electrically connected with rotary valve.
As further program of the utility model: described oil cylinder is connected with the plunger in the mud pump housing.
Compared with prior art, the beneficial effects of the utility model are: in a working procedure, can set different pressure ratings at times, and carry out control automatically to it; The observed pressure that oil pump exports and setting pressure, as there is deviation, can be rectified a deviation automatically fast; Under guarantee setting pressure state, oil pump output flow with the instant flow Auto-matching of field demand, largely can reduce energy loss, improves effect, extend the working life of YB mud pump with plunger.
Accompanying drawing explanation
Fig. 1 is the structural representation of YB hydraulic plunger slurry pump automatic controller.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1, YB hydraulic plunger slurry pump automatic controller, comprises variable piston oil pump 1, variable piston 2, PC valve 3, relief valve 4, proportional pressure control valve 5, electrical power amplifier 6, pressure transducer 7 and PLC 8.Described variable piston oil pump 1 is provided with variable piston 2, described variable piston oil pump 1 oil outlet is provided with relief valve 4, described PLC 8 is electrically connected to proportional pressure control valve 5 by electrical power amplifier 6, PC valve 3 is provided with between described proportional pressure control valve 5 and variable piston oil pump 1, described PC valve 3 is connected with variable piston oil pump 1, described variable piston oil pump 1 oil outlet arranges pressure transducer 7, described pressure transducer 7 and PLC 8 are electrically connected, hydraulicchange-over valve 9 and rotary valve 10 is provided with between described variable piston oil pump 1 and oil cylinder 11, described hydraulicchange-over valve 9 is connected with rotary valve 10, described oil cylinder 11 is connected with the plunger 12 in the mud pump housing 13, by variable piston oil pump 1, variable piston 2, PC valve 3, relief valve 4, proportional pressure control valve 5, electrical power amplifier 6, pressure transducer 7 and PLC 8 form auto-supply system, through hydraulicchange-over valve 9 and rotary valve 10, pressure oil is sent into oil cylinder 11 again, promote plunger 12 and move in the mud pump housing 13.
Working principle of the present utility model is: for supporting pressure filter, PLC 8 sets the pressure rating required for day part, instruction signal is sent by PLC 8 during work, after electrical power amplifier 6 is amplified, send into proportional pressure control valve 5, proportional pressure control valve 5 can control at the pressure of day part to different brackets.If deviation appears in oil supply system observed pressure and setting pressure, the signal detected can be fed back to PLC 8 by pressure transducer 7, then delivers to proportional pressure control valve 5 after being rectified a deviation by PLC 8, readjusts pressure return setting value by proportional pressure control valve 5.Under day part setting pressure state, during initialization, hydraulic oil supply system provides peak rate of flow, when pressure filter along with filter chamber material matter is piled up, when needing flow to reduce, fuel pump outlet pressure P p will increase, when pressure is higher than proportional pressure control valve 5 setting pressure Ps, proportional pressure control valve 5 is opened, under the effect of pressure oil Pp, PC spool moves to left, the left chamber of pressure oil entering variable piston, makes oil pump output flow reduce, until be zero.When Pp is less than Ps, proportional pressure control valve 5 is closed, and under the action of the spring, PC valve 3 spool moves to right, and oil is rushed down by PC valve 3 in the left chamber of variable oil cylinder, and oil pump output flow increases.
Feature of the present utility model is:
(1) in a working procedure, different pressure ratings can be set at times, and control is automatically carried out to it.
(2) oil pump export observed pressure and setting pressure as there is deviation, can automatically rectify a deviation fast.
(3) under guarantee setting pressure state, oil pump output flow can with the instant flow Auto-matching of field demand.Therefore, this automatic control mode to hydraulic oil supply system, the pressure that YB mud pump with plunger can be made to export and flow change with field load to be done immediately to mate, and makes the output power of YB pump be constantly equal to field load demand power, like this, just largely energy loss is reduced.Improve effect, extend the working life of YB mud pump with plunger.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
