Description
Technical field
The present invention relates to plunger pump, a kind of screw mandrel drive plunger pump is provided especially.
Background technique
Plunger pump is widely used in the high pressure field, is the high pressure pump system that the oil hydraulic pump of other types such as vane pump, gear pump can't replace.Yet traditional plunger pump promotes the plunger to-and-fro motion because adopting asynchronous motor mostly is power source by cam mechanism, and its mechanical efficiency is low, and vibration noise is big, and volume is big, and weight is big, is not easy to carry and transport.
The tradition plunger pump is because the plunger stretching frequency is very high, need associated gear pump or vane pump or other high-capacity pumps, supply with hydraulic oil as rudimentary pump, avoid occurring vacuum, obtain stable hydraulic pressure output, therefore having a large amount of inside drain charges, is metering pump, causes entire pump origin system efficient to reduce.
Summary of the invention
Technical problem to be solved by this invention is that a kind of mechanical efficiency height will be provided, and low vibrations, noise are little, and volume is little, lightweight screw mandrel drive plunger pump.
In order to solve above technical problem, the invention provides a kind of screw mandrel drive plunger pump, the output shaft of stepper motor or actuating motor connects a screw mandrel or ball screw, on the nut kinematic pair of screw mandrel or ball screw axial plunger is installed, fixedly there is plunger pump cylinder body at the axial plunger two ends, two movement travel end points of nut kinematic pair are equipped with position switch, the signal of PLC control driver collection position switch, the drive waveforms of output commutation, control motor forward or reverse, make axial plunger to-and-fro motion between two plunger pump cylinder bodies, motor is converted to the straight line motion of plunger, its mechanical efficiency is much higher than cam mechanism.
The drive waveforms of PLC control driver output different frequency is controlled rotating speed of motor, further controls the speed of plunger, realizes that the plunger pump flow is adjustable.
Described screw mandrel or ball screw are that two ends are fixedly supported on the motor output shaft, or an end fixed support, the other end support of moving about.
Described plunger pump cylinder body bottom is provided with a fuel feeding interface.
When nut kinematic pair contacting travel switch, PLC control driver obtains electrical signal, the control wave of output commutation, thus the control motor constantly just changes, reverses, and realizes the axially reciprocating of plunger; PLC control driver can receive the drive waveforms that user instruction control PLC control driver sends different frequency, the rotating speed of control motor, thus the control velocity of plunger realizes that finally pump duty is adjustable.
Advantage of the present invention:
1) is different from traditional high-pressure plunger pumping system, do not need rudimentary pump;
2) use screw mandrel or ball screw as rotating to straight-line conversion, the mechanical efficiency height, the vibrations noise is little;
3) use stepper motor or actuating motor to substitute asynchronous motor, stability of flow, electrical machinery life is long;
4) rotating speed of PLC control driver control motor, thus the speed of control plunger realizes that pump duty is adjustable;
5) simple in structure, volume is little, and is in light weight, is easy to carry.
