Description

A water pump integrated measurement and control platform

technical field

The invention belongs to the technical field of measurement, and in particular relates to a water pump integrated measurement and control platform.

Background technique

The water pump controller is suitable for remote monitoring and management of water intake pumping stations, water plant pressurized pump stations, midway pressurized pump stations, and community pressurized pump stations in urban water supply systems. The management personnel of the pumping station can remotely monitor the working status and operating parameters of the on-site equipment in the monitoring center; remotely control the start and stop of the water supply equipment; and monitor the panorama or important positions in the station with images. The water pump controller starts and stops the water pump according to the detected water source status, pipeline water consumption and pipeline pressure changes and other data. At present, the intelligence of the water pump controller has been significantly improved, and it is easy to install. As long as the controller is directly connected to the pipeline, no external relay is needed to realize low-pressure water pumping and stop pumping at high pressure, so as to save energy and prolong the life of the pump. And realize the unattended operation of the water pump, which can completely replace the traditional system composed of pressure tank, pressure switch, water shortage protection device, check valve, four-way, etc. It is suitable for the automation of home and unit water supply and drainage systems and garden flower garden irrigation, and automatically maintains the pressure in the pipeline.

Before leaving the factory, the water pump controller usually needs to carry out various related performance tests. At present, there are many kinds of detection devices for various performance parameters of water pump controller products, but they all have their own shortcomings. For example, the common manual detection system is composed of mechanical pressure gauges, flow meters, mechanical valves and other devices. When testing the entire performance parameters, it is tested separately and step by step, resulting in low efficiency and poor accuracy. In addition, some semi-automatic detection systems are mainly composed of mechanical pressure gauges, flow meters, mechanical valves, solenoid valves and other devices combined with certain simple hardware relay circuits, which also have the disadvantages of low efficiency and poor accuracy. At present, there are fully automatic detection systems on the market, such as the Chinese invention patent "PLC and touch pump controller test system" with the patent number ZL201310005681.6, but this kind of test system has complex structure, large volume and single test data , and only a specific type of water pump controller can be tested individually during the test, for example, the simultaneous test of the centrifugal pump controller and the self-priming pump controller cannot be realized.

The centrifugal pump measurement and control circuit cooperates with the liquid level simulation module to realize the comprehensive test of the water supply mode, drainage mode and pressure mode of the vertical centrifugal pump.

Under the water supply mode, the three water level probes connected to the water supply high level push rod motor 14, the water supply level push rod motor 15, and the water supply low level push rod motor 16 are all submerged in the water during the initial condition, and the motor is in a stopped state. Afterwards, the electric control cabinet 4 controls the operation of the water supply high level push rod motor 14 to lift the high level water probe out of the water surface, then controls the water supply level push rod motor 15 to lift the middle water level probe out of the water surface, and then the water supply low level push rod motor 16 lifts the low water level probe out of the water surface , to simulate a water shortage state; at this time, the water pump controller 3 receives a corresponding voltage signal, and controls the vertical centrifugal pump 20 to start running to supply water. After a period of time, the electric control cabinet 4 controls the water supply low level push rod motor 16 to push the low water level probe to the water surface, then the water supply level push rod motor 15 pushes the middle water level probe to the water surface, and finally the water supply high level push rod motor 14 pushes the high water level probe to the water surface.

After a period of time, the electric control cabinet 4 controls the drainage low level push rod motor 12 to push the low water level probe to the water surface, then the drainage middle level push rod motor 11 pushes the middle water level probe to the water surface, and finally the drainage high level push rod motor 10 pushes the high water level probe to the water surface. Push it down to the water surface to simulate a full water state; at this time, the water pump controller 3 receives a corresponding voltage signal, and controls the vertical centrifugal pump 20 to start running to drain water. The drainage mode operates in a cyclical manner according to the above logic.

In the pressure mode, the pressure pointer of the pressure gauge 18 is located below the upper limit pressure pointer and above the lower limit pressure pointer in the initial condition; the vertical centrifugal pump 20 is in a stopped state under the control of the water pump controller 3, and the pressure gauge 18 The measured pressure value gradually decreases until the lower pressure limit is reached, the water pump controller 3 receives the circuit disconnection voltage signal, at this time the water pump controller 3 controls the vertical centrifugal pump 20 to start; after a period of time, the pressure of the pressure gauge 18 The value returns to between the upper limit pressure and the lower limit pressure. At this time, the vertical centrifugal pump 20 continues to run. When the pressure value of the pressure gauge 18 exceeds the upper limit pressure, the water pump controller 3 receives the circuit disconnection voltage signal again. At this time, under the control of the water pump controller 3, the vertical centrifugal pump 20 stops running; the pressure mode runs in a cycle according to the above logic.

It will be obvious to those skilled in the art that the present invention may be modified in various ways and such modifications are not to be regarded as departing from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of this claim.
