Description
Technical field
The invention belongs to slurry shield control technology field, slush pump and booster pump in especially a kind of slurry shield machine
It is electrical to improve control method.
Background technique
Slurry shield construction in, it usually needs by improve face dregs slurry transportation to excavation storehouse in and will open
It sweeps along the mud of dregs to be transported again to ground in digging storehouse and carries out mud and dregs separation, play key in this transmission process
Effect is exactly slush pump, and slush pump needs booster pump to pressurize to carry out at mud pump shaft sleeve recirculated water during operation
Supplement sealing.
In slurry shield construction, the electrical control of slush pump and booster pump is only simply opened and is shut down, and mud
Stock pump and booster pump oneself are also not provided with any electrical interlocks control unit, booster pump be set on for a long time state and nobody
It is just easily damaged when guard, when booster pump damage, slush pump causes to damage at its axle sleeve due to not having pressurized circulation water, mud
Stock pump cisco unity malfunction influences slurry shield construction speed.
Summary of the invention
In view of the above-mentioned problems, the present invention provides the electrical improvement of slush pump in a kind of slurry shield machine and booster pump controls
Method, this electrically improves control method by installing different electrical components additional at slush pump and booster pump, both can be to muddy water
The working condition of booster pump is monitored in real time in cyclic process, and is protected to greatest extent to slush pump, has ensured mud
The normal construction of water quality structure.
For achieving the above object, the present invention adopts the following technical scheme:
The electrical improvement control method of slush pump and booster pump in a kind of slurry shield machine, this, which electrically improves control method, makes
Pressure sensor, photoelectric converter and electromagnetic flowmeter are used, slurry shield machine itself has PLC control system, it is characterized in that:
Booster pump control switch and slush pump control switch are cascaded and pass through optical fiber and is transferred to PLC control system
Long-range start and stop are implemented by shield machine, install pressure sensor, electromagnetic flowmeter, pressure sensor additional respectively in the exit of booster pump
And electromagnetic flowmeter couples photoelectric converter respectively, which couples with the photoelectric converter of shield machine, shield machine
Photoelectric converter couples with PLC control system, so far completes the electrical improvement connection of slush pump and booster pump；
Coupled by above-mentioned electrical improvement, the chain control mode of slush pump and booster pump is as follows in slurry shield machine:
When shield driver remote opens booster pump and reaches setting pressure and setting flow, the pressure of exit configuration
Its electric pressure signal and flow electric signal are delivered separately to photoelectric converter and are transformed into pressure by sensor and electromagnetic flowmeter
Optical signal and flow optical signal, the pressure optical signal and the flow optical signal are transferred to the light of slurry shield machine by optical fiber
The pressure optical signal and the flow optical signal are transformed into the pressure again by electric transducer, the photoelectric converter of slurry shield machine
Force electrical signal and the flow electric signal are simultaneously separately input to PLC control system, and PLC control system passes through to the pressure telecommunications
Number and the flow electric signal identification open slush pump；
When shield driver remote open booster pump but its not and reach setting pressure and setting flow when, PLC control system
The pressure value of booster pump and flow value at this time will be shown on display screen and makes alarm, and PLC control system not starts mud
Pump；
When slush pump and booster pump run well, PLC control system display screen will show booster pump at this time respectively
With the pressure and flow of slush pump；
When setting pressure or setting flow is not achieved because of failure at work in booster pump, PLC control system display screen is just
Abnormal show can be made to this, should close slush pump immediately at this time, when booster pump reaches setting pressure or setting flow, pass through
PLC control system could open slush pump.
Due to using technical solution as described above, the present invention generate it is following the utility model has the advantages that
1, the present invention has distinguished installation pressure sensor, electromagnetic flowmeter at booster pump outlet, passes through photoelectric converter
Couple with the PLC control system of shield machine, the electrical control for solving slush pump and booster pump is only simply opened and shut down
Problem makes to be sufficiently sealed at mud pump shaft sleeve, improves the construction speed of slurry shield.
2, booster pump control switch and slush pump control switch are cascaded and pass through optical fiber and be transferred to PLC control system
System may be implemented shield machine and implement long-range start and stop.
3, pressure sensor, electromagnetic flowmeter are installed additional respectively in the exit of booster pump, passes through photoelectric converter and shield
PLC control system couples after machine, to reach the purpose of long-range chain control.
Specific embodiment
The invention solves the long-range chain control problem between slush pump and booster pump and shield machine, focus on solving with
Lower problem:
1, when shield driver remote opens booster pump and reaches setting pressure and setting flow, the pressure of exit configuration
Its electric pressure signal and flow electric signal are delivered separately to photoelectric converter and are transformed into pressure by force snesor and electromagnetic flowmeter
Power optical signal and flow optical signal, the pressure optical signal and the flow optical signal are transferred to slurry shield machine by optical fiber
The pressure optical signal and the flow optical signal are transformed into described by photoelectric converter, the photoelectric converter of slurry shield machine again
Electric pressure signal and the flow electric signal are simultaneously separately input to PLC control system, and PLC control system passes through to the pressure electricity
Slush pump is opened in the identification of signal and the flow electric signal.
2, when shield driver remote open booster pump but its not and reach setting pressure and setting flow when, PLC control system
The pressure value of booster pump and flow value at this time will be shown on system display screen and makes alarm, and PLC control system not starts mud
Stock pump.
3, when slush pump and booster pump run well, PLC control system display screen will show respectively and be pressurized at this time
The pressure and flow of pump and slush pump.
4, when setting pressure or setting flow is not achieved because of failure at work in booster pump, PLC control system display screen
Abnormal show will be made to this, should close slush pump immediately at this time, when booster pump reaches setting pressure or setting flow, led to
Slush pump could be opened by crossing PLC control system.
The specific connecting mode of pressure sensor, photoelectric converter and electromagnetic flowmeter is referring to the technical solution, not separately
It repeats.Although any technology barrier is not present in the connection between above-mentioned each electrical component, the effect to solve the above problems is true
It is it will be apparent that avoiding slush pump because water-stop insufficient pressure leads to axis after booster pump and slush pump implementation chain control
The case where set abrasion delays the duration is very, directly or indirectly to slush pump using and protecting in slurry shield construction
Generate millions of first economic benefits.
