As shown in figure 1, a kind of high-pressure plunger pump interlock protection control system, including interlock protection controller 8 and interlocking are protected
Frequency converter, outlet pressure transmitter 5, inlet pressure transmitter 4, inlet flow rate transmitter 6 that shield controller 8 is connected respectively, institute
Frequency converter connection piston pump motor is stated, the outlet pressure transmitter 5 is arranged on outlet line, the outlet pressure transmitter
5 connection pressure regulators 7, the pressure regulator 7 connects frequency converter, the inlet pressure transmitter 4 and inlet flow rate pick-up
Device 6 is arranged in inlet line, and the interlocking protective system also includes vibration transmitters 3, and the vibration transmitters 3 are arranged on post
Fill in pump pump head position, the connection interlock protection of vibration transmitters 3 controller 8.
Interlock protection control system also includes water transmitter 2, and the water transmitter 2 is arranged in shaft joint casing,
The connection interlock protection of water transmitter 2 controller 8.
The interlock protection control system also includes temperature transmitter 1, and the temperature transmitter 1 is arranged on crank position,
The connection interlock protection of temperature transmitter 1 controller 8.
Interlock protection controller 8 connects workstation servers by the network switch, and the workstation servers pass through net
Network interchanger sends control instruction to interlock protection controller 8.
Wherein, the interlock protection controller 8 is one kind in PLC or DCS controllers.
Specific method is as follows：
The control method includes inlet pressure control method, pump head vibration control method, filler leak control method, song
Axle box oil temperature control method, outlet pressure control method, the inlet pressure control method are according to inlet flow rate and pressure
Threshold value is controlled to motor, the pump head vibration control method, and when pump head vibration exceedes given threshold, controlled motor stops fortune
OK, the filler leak control method, when filler leak, controlled motor is out of service, the crankcase oil temperature control method
It is, according to the oil temperature measured, motor to be controlled, the outlet pressure control method is that the pressure in exit is interlocked
Control.
The inlet pressure control method, specific method is as follows：
S101, it is less than given threshold when inlet pressure or flow；
S102, interlock protection controller cut-out motor control loop, realize automatic stopping.
When plunger pump inlet pressure is low or during low inlet flow rate, illustrates that system feed flow is not enough, such liquid measure of the entrance pump housing
Deficiency, causes piston and cylinder body Gan Mo, causes cylinder body and piston to pull, damaged pump.As long as therefore inlet pressure or flow
Less than the threshold value of setting, with regard to automatic cut-off motor control loop, operation is left the motor off, automatic stopping is realized
The pump head vibration control method, when the amplitude that pump head vibrates exceedes given threshold, the cut-out of interlock protection controller
Motor control loop, voluntarily stops.When longtime running, after abrasion in pump head is increased, vibration amplitude increase, it is necessary to stop into
Row pump head is safeguarded, motor control loop is cut off after more than given threshold, operation is left the motor off.
The filler leak control method, exceedes given threshold, interlock protection controller is cut when detecting water in filler
Power machine control loop, voluntarily stops.After filler leak, water may enter crankcase by crankcase oil seal, cause machine oil
Emulsification, reduces the lubricant effect of bent axle, causes Crank shaft Damage.Therefore when water detected value is higher than threshold value, automatic cut-off motor
Control loop, leaves the motor off operation.
The crankcase oil temperature control method, when temperature transmitter detects crankcase temperature more than given threshold, interlocking
Controller cut-out motor control loop is protected, is voluntarily stopped.Crankcase oils temperature detector surveys the lubrication circumstances for detecting bent axle, when
Lubricate good under normal circumstances, temperature will not transfinite.Crankshaft lubrication is reduced after oil level is reduced, and amount of heat is produced, by oil temperature
Rise.Or after crankcase is intake due to bent axle moving back and forth Jiang Shui with oil carry out high speed stirring after, lubricating oil emulsion, bent axle
Lubrication reduction, producing heat causes oil temperature to raise.Both of these case will cause bent axle to be scrapped.Therefore crankcase oil temperature threshold is set
Value, after threshold value is reached, frequency converter is shut down, no longer output frequency, realizes automatic stopping.
The outlet pressure control method, specific method is as follows：
S201, when plunger pump outlet pressure be higher than given threshold when, PID regulator output reduce, control frequency converter it is defeated
Go out frequency reduction, motor speed reduction, the reciprocating frequence of plunger pump is reduced, then the outlet pressure of pump reduces, and outlet pressure is progressively
Return to given threshold；
S202, when plunger pump outlet pressure be less than given threshold when, PID regulator output increase, control frequency converter it is defeated
Go out frequency increase, motor speed is improved, the reciprocating frequence of plunger pump is improved, then the outlet pressure increase of pump, outlet pressure is progressively
Return to given threshold；
S203, when outlet pressure higher than set high high threshold when, cut off motor control loop, stop frequency converter, realize from
Dynamic parking.After outlet of plunger pump valve is closed or outlet line blocks, outlet of plunger pump pressure is quickly raised, and causes input work
Rate increases, and the uncontrollable outlet pressure of PID regulator, causes motor overload and burns motor, therefore when outlet pressure is higher than
When setting high high threshold, motor control loop is cut off, stops frequency converter, realizes automatic stopping.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
