Description
Technical field
This utility model relates to a kind of control device, particularly relates to a kind of control device protecting water pump overload operation.
Background technology
Run in water pump operation process in the past; protection water pump can only protect the properly functioning of water pump from the height of water pump operation electric current; for the water system of some variable lifts, (after water pump pipe network after the pressurizing and some deep well water pump water levels decline, actual lift changes under relatively larger premise; pump working state) water pump initial stage electric current is excessive, causes protection circuit operation.If crossing current setting value too high, the long-time overload operation of motor in During Process of Long-term Operation, motor ages is fast, it is easy to motor damage, thus affecting production.
Originally shortcoming was directly initiated as follows:
1, starting protection circuit is the detection to current of electric; often in a lot of occasions of practical application; the water pump initial stage is due to anhydrous in pipeline; the lift of water pump initial stage lift and pumps design comes in and goes out relatively larger; water pump initial stage low lift, flow are big; water pump electric current is big, causes the original startup device of water pump to protect shutdown because electric current is big, even seriously arrives equipment and cannot run at all.
2, in some occasion start-up courses, need to run work valve Guan Bi is started, after having started, valve is opened, increase operation work workload.
3, in water pump is properly functioning, particularly under many pumps pattern, often the female pipe caliber net of design is in charge of greatly than water pump, valve wide open state often water pump supercurrent, carries out electric current is regulated only by valve.
4, in conventional deep well water pump mounting design process, dynamic water level and hydrostatic level drop are relatively larger, at the starting mode of pump initial stage, owing to water level is overhead closer, super lift uses, and flow is big, thus electric current is big, it is impossible at design of electrical motor electric current section operation, affects water pump and use.
Utility model content
This utility model provides a kind of control device protecting water pump overload operation, to solve prior art Problems existing.
This utility model is by the following technical solutions:
A kind of control device protecting water pump overload operation, including PLC control cabinet, pump motor and the electrically operated valve that is arranged on water-filled pipe；Being provided with the current sensor of Acquisition Circuit electric current on the main circuit of described pump motor, the signal of reception is passed to PLC control cabinet by current sensor, and PLC control cabinet is connected with the electric valve actuator being used for the opening degree of electrically operated valve is controlled.
Also including pressure transducer, described pressure transducer is arranged on water-filled pipe, and the descaling line pressure signal recorded is passed to PLC control cabinet.
The initial opening degree of described electrically operated valve is between the opening degree and the opening degree of maximum folding condition of electrically operated valve closure state.
The beneficial effects of the utility model: 1, the computing by PLC of the electric current of the motor of water pump so that water pump energy longtime running, at rational lift and flow rate zone, protects equipment, extends service life of equipment.2, at some complicated water supply occasions (building construction, agricultural well irrigation), pipeline arranges pressure transducer, at utmost ensure that water yield and run unreasonable problem owing to lift change exists motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and detailed description of the invention, this utility model is described in further detail.
This utility model provides a kind of control device protecting water pump overload operation, it includes PLC control cabinet, also include being arranged on pipeline, the water in pond is pumped out to the pump motor on water-filled pipe, also include the electrically operated valve being arranged on water-filled pipe, by gathering the real-time current of pump motor, after PLC control cabinet processes, send a signal to the YE of electrically operated valve, the YE opening degree according to signal control valve door, control the hydraulic pressure of water-filled pipe, protection water pump occurred that stream and the pressure due to copper plumbing road change and water pump valve cannot fully open and there is flow and cross minor issue to greatest extent.
Specifically, the main circuit of pump motor is provided with and gathers the current sensor of electric current on motor circuit, after current sensor collects real-time current current on motor main circuit, convert electrical current into the current signal of 4 ~ 20 milliamperes, it is sent to PLC control cabinet, the rated current signal of the current demand signal received with the motor prestored is carried out simple subtraction by PLC control cabinet, sending the current signal of 4 ~ 20 milliamperes to the current input terminal of YE according to operation result, the opening degree of electrically operated valve is adjusted by YE.
At the water pump operation initial stage, owing to the starting current of motor is often very big, it is thus desirable to pre-set the length threshold set aside some time in PLC, subtraction is not carried out in time period, the opening degree of electrically operated valve is arranged on correct position simultaneously, namely the initial opening degree of movable valve is between the opening degree and the opening degree of maximum folding condition of electrically operated valve closure state, such as it is arranged on centre position, or it can also be provided that other suitable opening degree positions, it is to avoid cause the ordinary action of equipment owing to valve opening degree is excessive and electric motor starting electric current is excessive.
This utility model can also include pressure transducer, particularly in the occasion needing certain pressure to carry out pump water, such as during building water supply, loine pressure needs to reach certain numerical value, it is thus desirable to arrange pressure transducer on pipeline, the descaling line pressure recorded is passed to PLC control cabinet, the current value of the pressure conversion that PLC control cabinet records according to current value and the pressure transducer of current sensor and load current value with motor carry out computing and draw the difference with rated current, difference is sent to YE and controls the opening degree of valve.
This utility model has the advantages that
1, the computing by PLC of the electric current of the motor of water pump so that water pump energy longtime running, at rational lift and flow rate zone, protects equipment, extends service life of equipment.
2, by the intervention of PLC, water pump and DCS system slitless connection can be controlled so that controlling at large-scale operating mode enterprise energy real time inspection motor operating parameter, complete the many data acquisition and processing (DAP)s of water pump.
3, measure in real time by arranging pressure transducer in some complicated water supply occasions (building construction, agricultural well irrigation), at utmost ensure that water yield and run unreasonable problem owing to lift change exists motor.
