A kind of novel hydraulic gear distributor, as shown in Figure 1, auxiliary including distributor body and distributor body side
Help driving device；The distributor body includes several gear pumps 2 being arranged in "-" type in shell 1, each gear pump 2
Pump shaft is connected by shaft coupling 3；The auxiliary drive includes auxiliary drive motor 4, the output of the auxiliary drive motor
The input shaft 6 of the gear pump interior with distributor body, close to the auxiliary drive motor side of axis 5 is connect；The shell and auxiliary
The protective cover 7 for covering in auxiliary drive motor output shaft and gear pump input shaft is equipped between driving motor.Using anti-
Shield is reliably protected to output shaft 5, input shaft 6 and for shaft coupling connecting the two.Unexpected touching is prevented, is prevented
Security risk also ensures reliable transmission torque.In general, protective cover be detachably arranged in shell and auxiliary drive motor it
Between, it can easily dismantle, convenient for assembly and maintenance.
The output shaft of above-mentioned auxiliary drive motor is torn open by the input axis connection of the corresponding gear pump of shaft coupling, installation
It unloads conveniently.Here the strong flexible clutch of anti-twisting property may be used in shaft coupling, avoids occurring when pump shaft stand under load is unbalanced
The case where off-axis.
The position corresponded on above-mentioned shell between every two gear pump is equipped with liquid outlet 8.Corresponded on above-mentioned shell it is each go out
Liquid mouth is equipped with inlet 9.Fluid flowing is smooth, will not be limited, as long as gear revolution speed is suitable, fuel feeding distribution is reasonable, you can
Reach stable fuel feeding.
PLC control system is installed on above-mentioned auxiliary drive motor, which connects with external warning device
It connects.The torque of auxiliary drive motor is detected using PLC, specifically, can be auxiliary drive motor output shaft and connect
Torque speed sensor is set between the input shaft of the gear pump connect, PLC control system signal is given using the sensor feedback,
PLC control system can be by the sensor signal obtained in real time compared with preset value, and when judging that torque is more than preset value, explanation has
Impurity or viscosity are higher, then PLC control system sends out instruction, control external alarm and send out alarm signal, remind related
Personnel are allowed to handle.
In addition, servo motor may be used in auxiliary drive motor, when PLC control system judges to have impurity in the oil of source or glues
When degree is higher, control signal is sent out, control servomotor improves rotating speed, ensures rational fuel delivery.It should be noted that utilizing
Other technological means, make PLC system obtain motor output shaft change in torque also can, as long as realizing corresponding testing goal,
Details are not described herein.
For in the prior art, gear distributor cannot achieve lacking for synchronous distribution flow with high accuracy in the process of running
It falls into, in an alternative embodiment, overflow mechanism is set at each liquid outlet, specifically, overflow mechanism may include pair
Overflow valve at each liquid outlet should be set, and the storage container of the overflow valve and external oil sources passes through piping connection.Can have
The charge oil pressure of each liquid outlet of guarantee of effect is constant, it is ensured that equipment uses reliable and stable, and extra grease flows back into again
Oil sources.Even if applying in complex dielectrics, by setting the Opening pressure of overflow valve, charge oil pressure (stream can be accurately controlled
Amount).It should be noted that it is equipment fuel feeding that each liquid outlet, which is usually all by pipeline, above-mentioned overflow valve can be arranged
It is connected on the pipeline of liquid outlet, other arrangements can also be used, it, can be effective as long as realizing voltage stabilizing, overflow effect
Ensure the stability of fuel feeding, protects equipment.
When this mekydro distributor works, as shown in Figure 1, arrow direction is media flow direction, entered by lower part, is situated between
Matter drives gear pump rotation, while by auxiliary drive motor auxiliary drive gear distributor.Motor with driving torque difference
The different current signal of PLC control system is fed back to, if the current signal is good fortune within the scope of artificial established standards
Row sends out instruction, control warning device sends out alarm signal and feeds back to accordingly if exceeding critical field by PLC control system
Operating personnel.Using present dispenser, the security reliability of product can be improved, improve working efficiency.
Gear distributor in the prior art, if medium is high viscosity or the complicated grease there is also other structures
(such as heavy duty gear grease containing fiber), in the operation for increasing gear by will appear accumulation residue when gear distributor
Resistance can cause gear distributor to block, and medium can equally be flowed out by the small flow of gear clearance after there is choking phenomenon, be caused
Flow is unable to precise synchronization, or even influences normal use.The invention using motor assist drive gear distributor, complete gram
Take above-mentioned phenomenon, in oil sources fuel cut-off, also can independent operating, avoid accumulation residue.
In addition, in the prior art, when gear distributor oil sources is run, operating personnel need to tear gear distributor open
Unloading could check whether the distributor can use, and the invention, can be to gear distributor master by auxiliary drive motor
Dynamic driving, operating personnel can inspect periodically gear distributor, assisted by starting by setting PLC control system
Driving motor checks corresponding electric current, you can realize the regular job for checking gear distributor, it is convenient and efficient.
The invention is simple in structure, reasonable design, carries out active drive by auxiliary drive motor, it is entirely avoided resistance
Phenomenon is filled in, also, by PLC control system feedack, can timely and conveniently control the working condition of gear distributor.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection domain within.
