Description
Technical field
The utility model relates to a kind of pressurized oil system, specifically a kind of energy-saving oil pressing system.
Background technique
The pressurized oil system equipment of existing product line is primarily of equipment compositions such as fuel tank, oil pump, control valve member, oil hydraulic cylinders.The pump that pressurized oil system is selected is common constant-flow pump, and this pump energy consumption is large, the not tube apparatus whether action of this oil pump, oil pump is in external maximum for oil condition all the time, export the pressure oil of constant flow rate, and make the motor of drive oil pump be in high load condition all the time, the electric energy consumed is very large.
Existing approximate schemes still adopts quantitative oil pump to export constant flow for executive modules such as oil cylinders and provides oil hydraulic power.When the executive modules such as oil cylinder are failure to actuate, when energy storage pressure increases to certain pressure, oil pump cuts out, during executive module action, energy storage pressure decline gear pump starts, but the flow that oil pump exports is still constant, and easily cause pressure transient and frequent start-stop oil pump, inapplicable large discharge occasion.
Existing oil pump, due to structural reason, can only provide the pressure oil of constant flow rate, can not change flow along with the action demand of equipment, and the oil got through constant flow rate oil pump just flows back to fuel tank without use, waste electric energy.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of energy-saving oil pressing system, and this pressurized oil system accurately can control equipment, thus realizes the object of saving power consumption.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of energy-saving oil pressing system, comprise oil pump, described oily delivery side of pump is connected with pipeline, be oil cylinder fuel feeding by pipeline, described oil pump is variable capacity oil pump, and described variable capacity oil pump changes flow by swashplate angle, and variable capacity oil pump swashplate angle is detected by angle transducer; Along pipeline fuel feeding direction, described pipeline is disposed with ratio adjusting valve, flow transducer, the first pressure transducer, one-way valve, the second pressure transducer and some accumulators, the swashplate angle driver of described ratio adjusting valve controlled variable oil pump, described accumulator is provided with the energy storage sensor detecting accumulator state, described angle transducer, ratio adjusting valve, flow transducer, the first pressure transducer, the second pressure transducer are connected with programmable controller PLC respectively with energy storage sensor.
The utility model pressurized oil system design and installation flow and pressure transducer on fuel pump outlet pipeline detect rate of discharge and pressure, and flow pressure electrical signal is passed to programmable controller PLC, perform to final controlling element to oil outlet pump opening degree command after programmable controller PLC calculates, and feed back oil pump aperture to programmable controller PLC by angle transducer, form closed loop control.
The utility model adopts intelligent variable oil pump to provide pressure oil for producing line, can provide suitable flow, thus the motor power consumption of drive oil pump is reduced along with the different demands of device action.By accurate control, lower power consumption can be realized.And oil pump when being in low discharge load less, can extension device working life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of energy-saving oil pressing system, the outlet of its oil pump 1 is connected with pipeline, be oil cylinder fuel feeding by pipeline, described oil pump 1 is variable capacity oil pump 1, adopts Variable plunger pump, adjusts oil pump flow by adjustment variable head tilt angle, namely change flow by swashplate angle, variable capacity oil pump 1 swashplate angle is detected by angle transducer 2 (or position transducer).
Along pipeline fuel feeding direction, described pipeline is disposed with ratio adjusting valve 3, flow transducer 4, first pressure transducer 5, one-way valve, the second pressure transducer 7 and some (one or more) accumulator 9.
The swashplate angle driver of ratio adjusting valve 3 controlled variable oil pump 1.
Flow transducer 4 is for detecting the flow on oil feed line.
First pressure transducer 5, second pressure transducer 7 detects the oil pressure of one-way valve 12 both sides respectively, the load of the known oil pump 1 of pressure detected by the first pressure transducer 5; The pressure detected by the second pressure transducer 7 can know the pressure of pressurized oil system upper cylinder 11.
Accumulator 9, for oil in reserve, is provided with the energy storage sensor 8 of accumulator 9 state that detects (namely whether storing up full).
Above-mentioned angle transducer 2, ratio adjusting valve 3, flow transducer 4, first pressure transducer 5, second pressure transducer 7 are connected with programmable controller PLC 6 respectively with energy storage sensor 8, programmable controller PLC 6 receives the signal of above-mentioned device, programmable controller PLC 6 is according to above-mentioned calculated signals, by the adjustment of programmable controller PLC 6 control ratio modulating valve 3, monitoring flow, for equipment provides required flow in real time.
When going out pan feeding, solenoid valve 10 action in oil supply system, variable capacity oil pump 1 fuel feeding, the flow lacked can provide required flow by the multiple accumulators 9 increased.Because peak period only had for 30 to 60 seconds actuation time, multiple accumulators 9 of increase enough provide the fuel delivery during this period of time.
And producing (when normally producing, solenoid valve 10 is failure to actuate) when line equipment is in less action, variable capacity oil pump 1 provides flow for accumulator 9, makes its accumulation of energy to maximum rating, next time is with being product line fuel feeding with variable capacity oil pump 1 during oily peak period simultaneously by the time.Flow transducer 4, first pressure transducer 5, second pressure transducer 7, accumulator 9 energy storage sensor 8 and angle transducer 2 will be installed on pipeline, and pass through the adjustment of programmable controller PLC 6 control ratio modulating valve 3, monitoring flow, for equipment provides required flow in real time.Such variable capacity oil pump 1 energy accurately fuel feeding, empirical tests, adopts pressurized oil system of the present utility model that every bar can be made to produce line and saves power consumption 20-30 ten thousand yuan every year.
Above-described embodiment limits the utility model never in any form, and the technological scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection domain of the present utility model.
