Circulating pump real time quantity regulation and control system

Abstract

The invention discloses a circulating water pump real-time amount adjustment control system, which comprises a multichannel water distribution apparatus, a boiler control apparatus and a water pump control apparatus.The multichannel water distribution apparatus distributes water according to water temperature and demand, wherein, a boiler control apparatus detects the maximum temperature, when boiler load increases and water temperature rises to set point, a water pump control apparatus will control variable-speed water pump to send out increased load heat, then, temperature drops to set point.Conversely, when a boiler load decreases and water temperature is lower than set point, a water pump control appatarus will control variable-speed water pump to reduce speed and flow, then temperature rises to set point.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to the technical field of real-time regulation of primary water in a boiler heating system. Background technique [0002] In the boiler heating system, primary water refers to the heat carrier that flows through the boiler and transmits the heat produced by the boiler. Among the connection methods between primary water and user circulating water (secondary water), some are indirectly connected through heat exchange equipment, and some are directly connected in a mixed manner. [0003] At present, in the boiler heating system, the primary circulating water pump of "concentrated boiler room high-temperature water heat exchange and heating" generally adopts the high power consumption adjustment method of "quality adjustment" or "quality and quantity mixed adjustment". "Primary circulating water pump" refers to the high-temperature water In the heat exchange heating system, t...

Problems solved by technology

[0005] 2. When the "climate compensation" heating method is applied to the secondary water, it is difficult to adjust the primary pipe network, and the best adjustment effect cannot be achieved, resulting in a periodic reduction in heating quality, increasing heat energy consumption and increasing power consumption

[0006] 3. The distance between each heat exchange station and the boiler room is different. When water quality is adjusted once, the near-end temperature rises quickly and the far end cools slowly, resulting in waste of heat energy; During adjustment, since each heat exchange station interacts with each other in the primary network, adjusting any system will change the total resistance coefficient of the primary network, resulting in changes in the flow of other heat exchange systems, so more manpower and material resources are required to participate in the adjustment, but Still can't achieve timely and effective adjustment effect
