供水稳压罐的选型报价与工作原理
系统采用供水稳压罐，缓冲压力波动和部分供水。在热力系统中，它主要用来吸收因温度变化而产生的工质体积。介绍了供水稳压罐的原理和结构。闭式水循环系统采用稳压罐，平衡水量和压力，避免安全阀频繁开启和自动补水阀频繁补水。AliWater稳压罐既能盛装膨胀水，又能补水。稳压罐可以充满空气，以获得更大的容积来容纳膨胀水。高低压供水稳压罐利用各自的压力向稳压系统并联补水。供水稳压罐原理当供水稳压罐用于系统时，由于系统的压力高于预充气体的压力，部分工质进入稳压罐，直至达到新的平衡。当系统压力再次升高时，系统的压力再次高于预充气体的压力，一部分介质进入罐内压缩罐内隔板之间的气体，压缩后的气体被压缩，压力升高。当压力上升到与系统压力相同的水平时，介质停止进入。相反，当系统压力下降，系统介质压力低于罐内气体压力时，供水稳压罐罐内的水会被气体挤出并加入系统，使系统压力升高，直至系统工作介质压力等于袋与罐之间的气体压力，而且水箱里的水不会加到这里的系统里，保持动态平衡。面向未来，上海龙亚将继续开发更多节能、环保、性价比更高的泵及泵系统产品，努力成长为更专业、更全面的管内流体泵组供应商。供水稳压罐1的结构。热力系统（锅炉、空调、热泵、热水器等）稳压罐选型：v=k·Q/AF AF=（P1+1）-（P2+1）/（P1+1）v=给水缓冲罐容积C=系统（包括锅炉、管道、散热器等）总水量，e=水的热膨胀系数（系统冷却时的水温与锅炉运行时Z高水温的水膨胀率之差），标准管泵组中e=0.0359（90℃），P1=给水调压井的预充压力，P2=Z系统运行时的高压（即起飞）系统安全阀压力）如果系统总水量为400L锅炉，安全阀的输出压力为3bar。AliWater供水稳压罐的容积应选择多少？V≈38.3l按大不小原则，Z接近50L供水稳压罐。2恒压系统供水稳压罐的选择（变频供水、恒压供水等）：为避免钛龙水泵频繁启动，供水稳压罐的调节量应满足一定时间内泵流量（L/min），计算公式为：k=水泵工作系数，随水泵功率的变化而变化。详见下表：K=水泵工作系数随水泵功率变化。Amax=Z大流量（L/min）Pmax=Z水泵工作压力高（水泵停止时系统压力）Pmin=Z水泵工作压力低（水泵启动时系统压力）ppre=供水调压罐预充压力v=供水调压罐容积，其中1HP（马力）=735kw以上内容为您介绍了供水稳压罐的原理和结构。如果您想了解我们的供水稳压罐，请直接在线咨询，我们会及时回复您。龙亚提供供水稳压罐、管中泵、地上泵、管内泵、污水泵、泵系产品及售后服务，为客户提供定制化解决方案。AliWater产品广泛应用于电厂、钢厂、矿山、石油天然气、市政及自来水厂、温泉、喷泉、工业应用、建筑及农业市场。

Selection, quotation and working principle of water supply surge tank
The system adopts water supply pressure stabilizing tank to buffer pressure fluctuation and partial water supply. In the thermal system, it is mainly used to absorb the volume of working fluid due to temperature change. The principle and structure of water supply pressure stabilizing tank are introduced. The closed water circulation system adopts pressure stabilizing tank to balance water quantity and pressure, and avoid frequent opening of safety valve and frequent water replenishment of automatic water replenishment valve. Aliwater pressure stabilizing tank can not only hold expansion water, but also make up water. The surge tank can be filled with air to obtain a larger volume to accommodate the expansion water. The high and low pressure water supply pressure stabilizing tanks make up water to the pressure stabilizing system in parallel by using their respective pressure. Principle of water supply pressure stabilizing tank when the water supply pressure stabilizing tank is used in the system, because the pressure of the system is higher than that of the pre charged gas, part of the working medium enters the pressure stabilizing tank until it reaches a new balance. When the system pressure increases again, the pressure of the system is higher than that of the pre charged gas again. A part of the medium enters the tank to compress the gas between the separators in the tank. The compressed gas is compressed and the pressure increases. When the pressure rises to the same level as the system pressure, the medium stops entering. On the contrary, when the system pressure drops and the system medium pressure is lower than the gas pressure in the tank, the water in the water supply pressure stabilizing tank will be squeezed out by the gas and added to the system, so that the system pressure will rise until the system working medium pressure is equal to the gas pressure between the bag and the tank, and the water in the water tank will not be added to the system here to maintain dynamic balance. Facing the future, Shanghai Longya will continue to develop more energy-saving, environmental friendly and cost-effective pumps and pump system products, and strive to grow into a more professional and comprehensive supplier of in pipe fluid pump sets. Structure of water supply pressure stabilizing tank 1. Type selection of pressure stabilizing tank for thermal system (boiler, air conditioner, heat pump, water heater, etc.): v = k · Q / AF AF = (P1 + 1) - (P2 + 1) / (P1 + 1) v = volume of feed water buffer tank, C = total water volume of system (including boiler, pipeline, radiator, etc.), e = thermal expansion coefficient of water (the difference between water temperature during system cooling and water expansion rate of high water temperature during boiler operation), e = 0.0359 (90 ℃) in standard tube pump group, P1 = pre charging pressure of feed water surge tank, P2 = high pressure (i.e. take-off) system during system operation If the total water volume of the system is 400L boiler, the output pressure of the safety valve is 3bar. What volume of aliwater supply surge tank should be selected? V ≈ 38.3l, according to the principle of large not small, Z is close to 50L water supply surge tank. 2. Selection of constant pressure water supply tank (frequency conversion water supply, constant pressure water supply, etc.): in order to avoid frequent start-up of titanium dragon water pump, the regulating amount of water supply tank should meet the pump flow (L / min) within a certain period of time, and the calculation formula is: k = working coefficient of water pump, which changes with the change of pump power. See the following table for details: k = variation of pump working coefficient with pump power. Amax = Z large flow (L / min) Pmax = Z high working pressure of water pump (system pressure when the water pump stops) Pmin = Z low working pressure of water pump (system pressure when the water pump starts) ppre = pre charging pressure of water supply surge tank v = volume of water supply surge tank, in which 1HP (horsepower) = 735kw, the above content introduces the principle and structure of water supply surge tank for you.
