Flow.
The utility model also solve it is existing draw water pump work when, easily occur compared with mass-flow, it is easy to hold the stone wrapped up under the arm
The defects of damage is caused to suction pump, there is provided a kind of suction pump based on PLC controls, with reference to liquid level gauge and flowmeter, PLC controls
Device can control suction pump in the operating power of different depth, ensure the safety of suction pump, also ensure that situation about drawing water is controllable.
Technical scheme is used by the utility model solves its technical problem：A kind of suction pump based on PLC controls, bag
Include：The pump housing of motor is internally provided with, the support frame that pump housing external support plays pump housing lower end is arranged at, is connected to outside support frame
Liquid level gauge, the PLC for being connected with liquid level gauge and being alarmed according to the minimum liquid level of liquid level gauge.Support frame supports pump
Body, pump housing lower end is avoided directly to be in contact with the bottom, pump housing lower end is with after water-bed be separated, improving pump housing lower end with lower portion
Water body flow, avoid mud, stone etc. from being stacked into around the pump housing, influence to draw water, liquid level gauge can be to depth of the pump housing in water body
Degree measures, or can determine depth of the pump housing with respect to water body, avoids the pump housing from exposing the surface and suction pump is dallied, burns
Suction pump, PLC are connected with alarm, and when minimum level is arrived in liquid level gauge instruction, PLC control alarm is carried out
Alarm, remind staff to adjust the depth of suction pump, so pay close attention to the depth of drawing water of suction pump all the time without worker, also without
Suction pump need to directly be sunk to the bottom, when drawing water, draw water suction pump the shadow that the water layer of suction inlet place depth is subject to
Maximum is rung, has the cooperation of liquid level gauge and PLC, then suction pump can gradually be moved from top to bottom so that suction pump
All the time work in optimal water body environment,
Preferably, the motor in the pump housing is variable-frequency motor, variable-frequency motor is connected with PLC and by PLC
According to the height of liquid level gauge come adjustment work power.Variable-frequency motor controls rotating speed by PLC, and liquid level gauge instruction is in height
During water level, motor runs at high speed, peak power work, when liquid level gauge instruction moves closer to low water level, PLC control electricity
Machine reduces rotating speed, reduces the flow that draws water.
Preferably, the port of export of the pump housing is provided with flowmeter, flowmeter is connected with PLC, is set in PLC
It is equipped with timer.Flowmeter can measure the flow that draws water of suction pump in real time, with reference to can measure the water drawn water, PLC after timer
Controller, with reference to the metering of current flow meter, can judge whether normal, the rotating speed of motor of pump housing work according to the instruction of liquid level gauge
Whether with flows match, and then to control alarm whether to send out into alarm signal, remind staff.
Preferably, connected between PLC and alarm using wireless telecommunications.Wireless telecommunications connect PLC
With alarm, such alarm and the distance between PLC are unrestricted, facilitate staff to manage.
Preferably, the front end of the pump housing is provided with screen pack, the height of screen pack is equal with the height where the blade that draws water
Together.The screen pack of pump housing front end can play a part of filtering.
Preferably, support frame includes at least three support feet, support feet flare struts arrangement, and the pump housing is in support
In frame, supporting and space is formed between the end of the pump housing and the end of support feet.
Preferably, being coated with protection network outside support frame, protection network envelopes support frame from the lower end of the pump housing to liquid level
Count the position between the top.
The beneficial effects of the utility model are：Support frame supports the pump housing, avoids pump housing lower end from being directly in contact with the bottom, pump
Body lower end is with after water-bed be separated, improving pump housing lower end with the water body flow of lower portion, avoiding mud, stone etc. from being stacked into the pump housing
Around, influence to draw water, liquid level gauge can measure depth of the pump housing in water body, or can determine the pump housing with respect to water body
Depth, avoid the pump housing from exposing the surface and suction pump is dallied, burn suction pump, PLC is connected with alarm, works as liquid level
When minimum level is arrived in meter instruction, PLC control alarm is alarmed, and reminds staff to adjust the depth of suction pump,
So pay close attention to the depth of drawing water of suction pump all the time without worker.
