Embodiment 1

[0025] For the current control of water pumps, three modes are generally adopted: centralized control, maintenance and local, that is, each water pump is in one of these three states. The meaning of centralized control is centralized and unified control, so the implementation of an intelligent control method for a multi-pump water supply system is based on a centralized mode.

[0026] The multi-pump water supply system selects the centralized mode, all the water pumps are in a stopped state, the programmable controller records the state of each water pump, and calculates the operation data of each water pump in real time. When the operator needs to start the multi-pump water supply system, enter the number of water pumps to start (the number entered is not greater than the number of water pumps in the centralized mode), and press the start button to automatically select the most qualified water pump to start.

[0027] In the multi-pump water supply system, 7 water pumps are ta...

Embodiment 2

[0030] On the basis of the start-up of multi-pump groups, the control method for switching pumps in abnormal accidents is optimized.

[0031] The intelligent control method of the multi-pump water supply system, based on this method, the programmable controller detects and records the status, current, outlet pressure, total water flow, grid voltage and other data of each pump in real time. When the running water pump has the following conditions: the state of the running water pump changes, the working mode changes, the chain signal disappears, and the state signal changes suddenly; the current of the pump exceeds the rated current for a long time, or the current of the pump changes suddenly; There is a large deviation between the time and the outlet pressure of other pumps, or the outlet pressure of the pump changes suddenly; combined with the current of the pump, the outlet pressure of the pump, the total outlet water flow, the voltage of the power grid and the parameters of ...

Embodiment 3

[0034] On the basis of the start-up of the multi-pump group, the control method of the pumps to achieve the small cycle running time or the large cycle running time is optimized.

[0035]An intelligent control method for a multi-pump water supply system, based on this method, the programmable controller calculates and records the running time and stop time of each pump in real time. The cycle running time of the pump is divided into small cycle running time and large cycle running time. If the water pump reaches the small cycle running time, the operation of the water pump needs to be stopped, and the stopped water pump needs to be routinely overhauled; if the water pump reaches the large cycle running time, the operation of the water pump needs to be stopped, and the stopped water pump needs to be overhauled. The programmable controller records the current running time, total running time and stop time of each pump through mathematical calculation. Since the water pump start...

Abstract

The invention discloses an intelligent control method of a water supply system of a multi-pump unit. In the intelligent control method, a programmable controller, a monitoring computer, a detecting unit and the multi-pump unit are included, the status data and the operation data of the multi-pump unit are detected in a real-time manner by applying a detecting technology, the programmable controller receives detecting data, related water pumps are started selectively according to the self status and the operation condition of the multi-pump unit, the operation status of each water pump can be detected in a real-time manner when the multi-pump unit operates, abnormal problems are found in time, stand-by pumps are intelligently selected and converted, and the water pumps are prejudged and adjusted in advance. The intelligent control method can solve the problem that the water supply system of the multi-pump unit is cumbersome in manual operation and the device is unstable, reduces devicefault, and improves the reliability and the stability of the operation of the multi-pump unit. The intelligent control method is simple, stable and reliable in operation, and has a good popularizationand application value.

Description

technical field [0001] The invention relates to a control method for a water supply system, in particular to an intelligent control method for a multi-pump group water supply system. Background technique [0002] As a general-purpose machine, water pumps are widely used in agricultural irrigation, metallurgy, mining, electric power, chemical industry, municipal administration and many other fields, which determine the steady development of the national economy. The water pump control technology that affects the economy and stability of water pump operation has experienced the development process of manual-semi-automatic-automatic. With the development of detection technology and control technology in the 21st century, water pump control has gradually realized automatic control. However, the current industrial The manual operation of the multi-pump water supply system is cumbersome and the equipment is unstable. Contents of the invention [0003] The technical problem to b...
