Problems solved by technology

At present, the better water adding method for most factory mixing equipment is a single-channel "frequency conversion control pump + electronic flowmeter" system, but this metering control system has an unsatisfactory defect, that is, most water pumps use Centrifugal pump, due to the structural characteristics of this pump, when the system is just started, it takes a certain period of time for the pump to establish a stable pressure to overcome its own and pipeline resistance to achieve the stable flow requirements specified by the computer batching control system, which forms a Time difference, during this period, there is always a large gap between the water flow provided by the water pump and the flow requirement specified by the computer batching control system, that is, there is a hysteresis fluctuation process of ups and downs, especially when the pipeline is long , the hysteresis lasts longer, which is not conducive to the stable control of the water content of the discharge

Embodiment 1

[0047] refer to figure 1 , is a structural schematic diagram of Embodiment 1 of the present invention, a plant-mixed metering water supply system, comprising

[0048] A water tank 1, the water tank 1 includes a water outlet and a water inlet;

[0049] water pump 8;

[0050] The first water suction pipe 3, one end of the first water suction pipe 3 communicates with the water outlet of the water tank 1, and the other end of the first water suction pipe 3 communicates with the water pump 8;

[0051] Electronic flow meter 4, electronic flow meter 4 is connected on the first water suction pipe 3;

[0052] A computer batching control system 7, one end of the computer batching control system 7 is connected to the electronic flowmeter 4 through an electrical signal line, and the other end of the computer batching control system 7 is connected to the water pump 8 through an electrical signal line;

[0053] The frequency converter 6, the other end of the computer batching control sys...

Embodiment 2

[0067] Compared with Embodiment 1, the difference of this embodiment is that: the water pump 8 is a centrifugal pump, and the water pump 8 includes a pump body 8-1 and a drive motor 8-2, and the drive motor 8-2 is connected to the pump body 8 -1, the drive motor 8-2 is connected to the other end of the frequency converter 6 through wires.

[0068] In actual use: the water pump 8 includes a pump body 8-1 and a drive motor 8-2, the drive motor 8-2 is connected to the pump body 8-1, and the other end of the frequency converter 6 is connected to the drive motor 8-2 of the water pump 8 through a wire. 2 connection, after the frequency converter 6 receives the signal, the motor speed of the driving motor 8-2 of the water pump 8 is controlled by the frequency conversion current to control the water output of the water pump 8, and the accuracy of the water output of the water pump 8 is controlled through this structure.

Embodiment 3

[0070] Compared with Embodiment 2, the difference of this embodiment is that the pump body 8-1 includes a water inlet and a water outlet, and the water inlet of the pump body 8-1 communicates with the other end of the first suction pipe 3 , The water outlet of the pump body 8-1 communicates with one end of the water outlet pipe 9.

[0071] During actual use: the water extracted during the work of the water pump 8 enters the water inlet of the pump body 8-1 through the first water suction pipe 3, and then enters the water outlet pipe 9 from the water outlet of the pump body 8-1.

Abstract

The invention relates to the technical field of plant-mixing measuring water supply, in particular to a plant-mixing measuring water supply system and a use method thereof. Through cooperation of a computer batching control system, a reversing valve, a water return pipe and a water supply pipe, the water supply amount of a water pump is controlled by the computer batching control system, accuratewater supply to plant-mixing construction is realized, the discharging moisture content is controlled stably, the influence of fluctuations of the plant-mixing discharging moisture content is avoided,and the working efficiency is improved.

Description

[0001] Technical field [0002] The invention relates to the technical field of factory-mixed metering water supply, in particular to a factory-mixed metering water supply system and a use method thereof. Background technique [0003] The accuracy of the water metering system of the plant mixing equipment directly affects the stable state of the moisture content of the output of the plant mixing equipment. Only by ensuring the stable optimal moisture content of the output can the quality of construction be guaranteed. At present, the better water adding method for most factory mixing equipment is a single-channel "frequency conversion control pump + electronic flowmeter" system, but this metering control system has an unsatisfactory defect, that is, most water pumps use Centrifugal pump, due to the structural characteristics of this pump, when the system is just started, it takes a certain period of time for the pump to establish a stable pressure to overcome its own and pipel...
