On energy-saving technologies for circulating water pumps
Thread Content
Currently, both Shanghai and Hangzhou have technologies for modifying pump bodies after calibrating circulation pumps, but these technologies are kept confidential. I would like to ask the experts: how can the pump body of a circulating water pump be modified to improve efficiency and save energy? Please give me some advice.
I’ve heard of this issue, but I haven’t delved into it in detail. According to them, it should be: the existing pumps have their head and flow rates verified on-site again, and after taking the resistance into account, the parameters of the pumps are set anew. It’s to keep the pump in its optimal condition. If an elbow is added after the modification is completed, the pump will not be able to achieve the required head pressure. It’s not some kind of technology; it’s just the optimization of existing pumps. Without new technologies, how can one make money?
New technologies are something unexpected; it’s like everything becomes clear the moment you think about them!
How to ensure the adjustment of circulation water volume in winter and summer after the renovation? How to address this issue when adding coolers as part of the inspection and renovation work? I would also appreciate some guidance on the minimum elevation difference between the circulating pool and the pump
Our company is planning to have a company do it to see if energy can be saved It has been tested, and a solution is being prepared.
Some of this is true and some is false; it is true that pumps modified using the three-phase flow theory can achieve flow rates and head levels comparable to those of the original pumps, while at the same time reducing power consumption. The false statement is that in the case of flow head, at least one of the parameters does not reach the level of the original pump; as a result, power consumption decreases. Such a modification involves cutting the impeller.
Traditional circulating water pumps feature a horizontal dual-impeller design, resulting in low efficiency. Ternary design impellers can be used for replacement, which generally allows for a power savings of over 15%. Support the opinion from the 6th floor.
The circulating water pumps in our workshop utilize Delta’s variable frequency technology. This technology allows the pump’s speed to be reduced, thereby lowering the outlet pressure; this helps to reduce electricity consumption while still ensuring effective heat exchange. But the downside is that the investment is relatively large, and it takes time to see results. Moreover, the inverter capacitors are prone to damage, but a replacement or refund is provided.
