供水穩(wěn)壓罐的選型報價與工作原理
系統采用供水穩(wěn)壓罐，緩沖壓力波動和部分供水。在熱力系統中，它主要用來吸收因溫度變化而產生的工質體積。介紹了供水穩(wěn)壓罐的原理和結構。閉式水循環(huán)系統采用穩(wěn)壓罐，平衡水量和壓力，避免安全閥頻繁開啟和自動補水閥頻繁補水。AliWater穩(wěn)壓罐既能盛裝膨脹水，又能補水。穩(wěn)壓罐可以充滿空氣，以獲得更大的容積來容納膨脹水。高低壓供水穩(wěn)壓罐利用各自的壓力向穩(wěn)壓系統并聯補水。供水穩(wěn)壓罐原理當供水穩(wěn)壓罐用于系統時，由于系統的壓力高于預充氣體的壓力，部分工質進入穩(wěn)壓罐，直至達到新的平衡。當系統壓力再次升高時，系統的壓力再次高于預充氣體的壓力，一部分介質進入罐內壓縮罐內隔板之間的氣體，壓縮后的氣體被壓縮，壓力升高。當壓力上升到與系統壓力相同的水平時，介質停止進入。相反，當系統壓力下降，系統介質壓力低于罐內氣體壓力時，供水穩(wěn)壓罐罐內的水會被氣體擠出并加入系統，使系統壓力升高，直至系統工作介質壓力等于袋與罐之間的氣體壓力，而且水箱里的水不會加到這里的系統里，保持動態(tài)平衡。面向未來，上海龍亞將繼續(xù)開發(fā)更多節(jié)能、環(huán)保、性價比更高的泵及泵系統產品，努力成長為更專業(yè)、更全面的管內流體泵組供應商。供水穩(wěn)壓罐1的結構。熱力系統（鍋爐、空調、熱泵、熱水器等）穩(wěn)壓罐選型：v=k·Q/AF AF=（P1+1）-（P2+1）/（P1+1）v=給水緩沖罐容積C=系統（包括鍋爐、管道、散熱器等）總水量，e=水的熱膨脹系數（系統冷卻時的水溫與鍋爐運行時Z高水溫的水膨脹率之差），標準管泵組中e=0.0359（90℃），P1=給水調壓井的預充壓力，P2=Z系統運行時的高壓（即起飛）系統安全閥壓力）如果系統總水量為400L鍋爐，安全閥的輸出壓力為3bar。AliWater供水穩(wěn)壓罐的容積應選擇多少？V≈38.3l按大不小原則，Z接近50L供水穩(wěn)壓罐。2恒壓系統供水穩(wěn)壓罐的選擇（變頻供水、恒壓供水等）：為避免鈦龍水泵頻繁啟動，供水穩(wěn)壓罐的調節(jié)量應滿足一定時間內泵流量（L/min），計算公式為：k=水泵工作系數，隨水泵功率的變化而變化。詳見下表：K=水泵工作系數隨水泵功率變化。Amax=Z大流量（L/min）Pmax=Z水泵工作壓力高（水泵停止時系統壓力）Pmin=Z水泵工作壓力低（水泵啟動時系統壓力）ppre=供水調壓罐預充壓力v=供水調壓罐容積，其中1HP（馬力）=735kw以上內容為您介紹了供水穩(wěn)壓罐的原理和結構。如果您想了解我們的供水穩(wěn)壓罐，請直接在線咨詢，我們會及時回復您。龍亞提供供水穩(wěn)壓罐、管中泵、地上泵、管內泵、污水泵、泵系產品及售后服務，為客戶提供定制化解決方案。AliWater產品廣泛應用于電廠、鋼廠、礦山、石油天然氣、市政及自來水廠、溫泉、噴泉、工業(yè)應用、建筑及農業(yè)市場。

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.
