Abstract
The invention discloses an energy-saving transformation method and product of a low-resistance efficient circulating water system. The method is mainly characterized in that a bypass in parallel connection with a main path filter is arranged on a main path, and a valve or/and a bypass filter is/are arranged on the bypass. The filter is an element which has the most influence on pipeline resistance, a main path filter is provided with the bypass filter in a parallel-connection mode, the pipeline resistance can be obviously reduced, and energy consumption can be greatly reduced. In the water with the good water quality, the filter is only used on the occasion needing cleaning, a direct-through bypass can be added, that is, the valve is arranged on the bypass, and thus the valve is closed only when the pipeline is cleaned, the water passes through the filter, in the working process, the valve is opened, the water directly passes through the valve, the influence of the filter on the pipeline resistance can be completely avoided, and energy consumption can be obviously reduced. The main path filter is replaced with a large-caliber filter with the caliber larger than the aperture of the pipeline, a flange type check valve is replaced with a butt-clamp type check valve, according to the measures, the pipeline resistance can be reduced, and the energy consumption can be obviously reduced.

Brief description of the drawings
Fig. 1 is the schematic diagram of high-efficiency low-resistance circulation reducing energy consumption product of the present invention.
Fig. 2 is the schematic diagram of high-efficiency low-resistance circulation reducing energy consumption effect of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As Fig. 1, the present embodiment is a kind of high-efficiency low-resistance circulation energy-conserving reconstruction method, the parts such as it can be applicable to the circulation in the systems such as central air-conditioner, and its element mainly comprises the water pump 1, safety check 2, main road filter 3, the working host 4 that form loop, and working host 4 is air-conditioning.
The present embodiment high-efficiency low-resistance circulation energy-conserving reconstruction method is mainly that a bypass being in parallel with main road filter 3 is set on main road, and bypass is provided with valve 5 or/and bypass strainer 6.Filter is the element that affects pipe resistance most, and main road filter is arranged in parallel bypass strainer, can significantly reduce pipe resistance, and energy consumption is greatly reduced.And occasion better at water-quality ratio, that filter only need use in the time cleaning, can increase by a straight-through bypass, one valve is namely set in bypass, like this, only throttle down in the time of detergent line, make water pass through filter, and in the course of the work, open valve, make water directly pass through valve, thereby avoid the impact of filter on pipe resistance completely, can significantly reduce energy consumption.
Meanwhile, can also do following transformation: main road filter is replaced with to the large heavy caliber filter in relative aperture pipeline aperture; Safety check adopts Wafer Check Valves (replacing conventional flange-type safety check).These measures can reduce pipe resistance, significantly reduce energy consumption.
After above-mentioned transformation completes, then according to more water-change pump of new characteristic curve of pipeline, select suitable low-lift pump, and then reduce energy consumption.
Energy-saving effect illustrates in connection with Fig. 2, and in Fig. 2, A point is pumps design operation point, and H is rated lift, and Q is design discharge, and k1 is design characteristic curve of pipeline.B point is water pump real work point, and H1 is actual lift, and Q2 is actual meter flow, and k2 is actual characteristic curve of pipeline.C point is operation point after water pump technological transformation optimization, and H2 is lift after technological transformation optimization, and Q is flow after technological transformation optimization, and k3 is design characteristic curve of pipeline.H1-O-Q2-B-H1 is water pump actual power consumption signal area before technological transformation is optimized.H2-O-Q-C-H2 is water pump actual power consumption signal area after technological transformation optimization.H1-H2-C-Q-Q2-B-H1 is the actual economize on electricity signal of water pump area after technological transformation optimization.As can be seen from the figure, the power consumption of water pump before optimizing with respect to technological transformation, after technological transformation optimization, the power consumption of water pump significantly reduces, and at least can reduce by 60%.
