Hot water hydraulic balance problems in engineering

Thermostatic valve manufacturer to introduce many current hotel, the guesthouse, bath and hot water engineering of hydraulic imbalance problem is severe, causing local rob blows hot and cold water in water temperature, nozzle can't constant temperature water supply, water peak cold water or hot water is in short supply. At present, many hotels, hotels, bath and other hot water engineering of hydraulic imbalance problem is severe, causing local rob blows hot and cold water in water temperature, nozzle can't constant temperature water supply, water peak cold water or hot water supply, the existence of this phenomenon causes the waste of water resources on the one hand, on the other hand, as the operator, the guest loss is very serious. In hot water engineering, therefore, we must consider good hydraulic imbalance problem, and solved.

first we talk about design, now we have a lot of design are calculated according to the experience of the quota and water use and water peak of water consumption per unit time, we according to the water to determine the size of the pipeline and the pump flow, and then through calculation of the negative terminal, the size of the pump head to finally selected the pump model. Of such a process, the design and selection for the short line or system not complex hot water system, there will be no problem, but for long or complex system of hot water pipeline system often will appear a lot of unexpected problems, many times we are to solve these problems by increasing the pump head or variable frequency system to solve, but some of the system through these means or problem too. I had met a few of these systems, one is the peak water some out of hot water at the end, another system and this is just the opposite, local end not cold water, investigate its reason is caused by the hydraulic imbalance, the other is that there is no fully according to some central heating water to consider this problem, the pipe set is not reasonable.

in living hot water engineering because of the whole system is a variable flow water system, so a lot of hydraulic balance is complex in the field of heating hot water, some hydraulic balance regulating method in the field of heating hot water also can't use, but some of the basic line set or worthy of reference. Design, we, after the confirmation of the flow rate according to the head of each section and considering the size of the concrete pipe line layout, where the head is adequate, meet the flow under the condition of selecting smaller pipe; Where the water supply pressure is not very big, should choose appropriate crude pipeline, reduce to avoid the problem of local water grab. Also because we selected pump is according to the negative terminal to choice, so easy to cause local water points beyond the norm or average, so it's best in these lines to increase the resistance, to adjust the balance of the whole water system.
