Description
Technical field
The present invention relates to engineering machinery field, particularly relate to a kind of oil pump driving control system that integrates the multifunctional drill of long-spiral drilling machine, rotary drilling rig, hydraulic vibration driver.
Background technique
At present, in the piling machinery industry, long-spiral drilling machine, rotary drilling rig, hydraulic vibration driver etc. are several machines commonly used, mostly those are several is to adopt common three phase alternating current motor to remove to drive the oil pump power mechanism and then power source is provided, but because this power mechanism is permanent torque system, thus its to have power big, the stream that opens, has a power failure impacts characteristics such as big, there is the energy consumption height in corresponding its, shortcomings such as rate of fault height.
In addition, because what the mode of speed regulation of those machines generally adopted is that a grade step-down is arranged, it is a kind of mode of speed regulation with the common three phase alternating current motor of Frequency Converter Control, but, the speed adjustable range of common three phase alternating current motor is only limited between the 30Hz-50Hz in the reality, so the torque of its three phase alternating current motor output in reduction of speed also can and then descend, this is to run counter to the requirement that permanent torque is output as permanent torque.
In sum, therefore how to reduce the consumption of the energy and the rate of fault of machine, realize stepless time adjustment, it is problem demanding prompt solution for above-mentioned several machines that the requirement of permanent torque output is provided.
Summary of the invention
Based on the existing in prior technology problem, the object of the present invention is to provide a kind of multiple mechanical functions such as long-spiral drilling machine, rotary drilling rig, hydraulic vibration driver of integrating, and energy consumption is low and service behaviour is strong, rate of fault is low, more meets the multifunctional drill oil pump driving control system that permanent torque is output as permanent torque request.
To achieve these goals, the present invention has adopted following technical proposals:
A kind of multifunctional drill oil pump driving control system of the present invention, be connected in drilling rig hydraulic system, comprise controller, frequency variator, variable-frequency motor and oil pump, wherein, controller is crossed to frequency variator and is transmitted frequency conversion adjustment signal, frequency variator receives and adjusts the rotating speed that signal goes to adjust the working power frequency of variable-frequency motor and then changes variable-frequency motor according to this frequency conversion, thereby changes the output flow of the oil pump that links to each other with variable-frequency motor.
Further, described controller is programmable logic controller (PLC).
Further, described frequency variator is vector-control frequency converter.
Further, described oil pump is the triple gear pump.
Further, also comprise a display device, it links to each other with controller.
Further, also comprise a warning device, it is connected in controller.
Multifunctional drill of the present invention has the following advantages:
(1) than diesel oil as more environmental protection and energy saving of power source, economical and practical, and start and stop all very steady, and do not have heavy current impact;
(2) but because therefore stepless speed regulation of electric driving, speed adjustable range is big, and reliable operation, long-time running stability is strong, mechanical life is long;
(3) control simply, the automaticity height, the regular maintenance amount is few, and output characteristics satisfies the load performance requirement.
Description of drawings
Fig. 1 is the function block diagram that multifunctional drill of the present invention is used the oil pump driving control system;
Fig. 2 is the be electrically connected schematic representation of multifunctional drill of the present invention with the oil pump driving control system.
Embodiment
Come multifunctional drill of the present invention is described in further detail with the oil pump driving control system below in conjunction with accompanying drawing and specific embodiment.
The present invention is mainly at existing multifunctional drill and exists power big, starting and stop various shortcoming youngsters such as rush of current is big improves, it drives the mode of oil pump by variable-frequency motor, makes multifunctional drill to have and softly opens, stops, all non-impact current and stepless time adjustments.
Shown in Fig. 1, control system of the present invention comprises controller 10, frequency variator 20, variable-frequency motor 30 and oil pump 40; Wherein, controller 10 is mainly adjusted signal in order to produce a frequency conversion, and this signal sends to frequency variator 20 by circuit; Frequency variator 20 receives the power supply frequency that these frequency conversions are adjusted signal and begun to adjust variable-frequency motor 30, and then the rotating speed of variable-frequency motor 30 also changes thereupon, oil pump 40 output flows that link to each other with variable-frequency motor 30 from further change.
In the practical application, described controller 10 is for adopting programmable logic controller (PLC), start button set on itself and the multifunctional drill operating table is electrical connected, when multifunctional drill operates, the staff only need press this button, described controller 10 namely can produce the control signal of changing the frequency conversion rate, it is the actuating signal of frequency variator 20, this actuating signal sends to frequency variator 20 by circuit, immediately, frequency variator 20 internal processes begin computing and export a frequency values that is suitable for to variable-frequency motor 30, make that its rotating speed is changed, and then change the flow of oil pump 40 outputs.Wherein, the program in the described controller 10 is in design and the burned controller chip in advance, the general vector-control frequency converter of MV300 series that described frequency variator 20 can adopt Mai Gemite actuation techniques Co., Ltd to produce.
In addition, oil pump 40 of the present invention can adopt the triple gear pump.
In the present invention, in order to prevent frequency variator 20 short circuit in running, its current input terminal adopt be air-break switch as short-circuit protection, again, survey harmonic component less than 5% in order to ensure frequency variator 20 electric currents, in the circuit of frequency variator 20, installed the inlet wire reactor additional.When multifunctional drill is started working, controller starts, variable-frequency motor 30 is pre-set, be to turn round under the frequent rate of benchmark, this reference frequency is set at 10 hertz among the present invention, simultaneously, the personnel of controlling are the DC input voitage value of 0 ~ 10 volt of manual tune according to actual needs, this dc voltage value further inputs to controller 10, controller 10 is analyzed and is calculated after receiving this VDC, control frequency variator 20 operations according to the result after analyzing and calculating synchronously, thereby regulate the rotating speed of variable-frequency motor 30 exactly, make that at last the actual fuel delivery of oil pump 40 is consistent with the working flow demand of multifunctional drill.
