工程依据

方法

由流量和有效成分投加量计算有效成分需求，再使用输入的有效成分质量分数和产品密度筛选商品药剂进料、储存及泵流量。产品浓度与密度由用户输入，模型不会推断。

Active demand = flow × user-entered active dose × 0.001. Commercial product mass = active demand / user-entered active mass fraction, where fraction means active ingredient mass per commercial product mass.

Product solution volume = commercial product mass / user-entered product density (kg/L). Normal feed = daily solution volume / 24 h.

Working storage = daily product volume × storage days. Gross storage basis = working storage / usable storage fraction.

Minimum and maximum feed cases use the entered design doses. Required turndown = maximum / minimum feed when minimum feed is positive.

Pump-rate screening assumes entered duty pumps share the required feed equally. Pump staging/on-off control is not modeled.

范围 / 限制

每种药剂分别保留独立的投加和储存系统。根据已输入的数据评估可选的剂量范围、可用储量比例、密度和泵能力。
Each chemical has a separate storage and feed system. No cross-chemical arithmetic total is presented as a shared tank, feed, or pump sizing basis.
Does not select a manufacturer, size piping, determine material compatibility, predict product degradation, or replace tank-code design.
Pump capability is compared only with user-entered turndown data; this is a screening comparison and not a pump selection or performance guarantee.
Product active mass fraction and density are user-entered; solution concentration and dilution-water demand are not calculated. Storage volume is per chemical system; tank count is not calculated. No US-unit conversion path is implemented; inputs and outputs use SI units.
