🛢️ 液压压力与输出力（帕斯卡原理）Hydraulic Pressure Calculator
压力 P = F ÷ A（A = π d²/4）；按帕斯卡原理，大活塞输出力 F₂ = P × A₂ = F₁ × (d₂/d₁)²。本地处理。Pressure P = F ÷ A (A = π d²/4); by Pascal's principle the output force is F₂ = P × A₂ = F₁ × (d₂/d₁)². Processed locally.
使用说明与常见问题How-to & FAQ
「液压压力与输出力（帕斯卡原理）」是什么？What is the Hydraulic Pressure Calculator tool?
压力 P = F ÷ A（A = π d²/4）；按帕斯卡原理，大活塞输出力 F₂ = P × A₂ = F₁ × (d₂/d₁)²。本地处理。Pressure P = F ÷ A (A = π d²/4); by Pascal's principle the output force is F₂ = P × A₂ = F₁ × (d₂/d₁)². Processed locally.
如何使用「液压压力与输出力（帕斯卡原理）」？How do I use the Hydraulic Pressure Calculator tool?
填写输入力和输入活塞直径，即可得到液压压强 P = F ÷ A；再填写输出活塞直径，还会按帕斯卡原理得到输出力。结果会随输入实时更新。Enter the input force and input piston diameter to get the pressure P = F ÷ A; add the output piston diameter to get the output force from Pascal's principle. The result updates as you type.
行程？Stroke?
力放大 n 倍，输出活塞移动距离缩小为 1/n，功不变。Force grows n times while the output stroke shrinks to 1/n - work is conserved.
能举个计算实例吗？Can you show a worked example?
例如在「液压压力与输出力（帕斯卡原理）」中填 输入力 N = 1000，输入活塞直径 mm = 50，输出活塞直径 mm（可选） = 200，结果区显示：压力：509.3 kPa；巴：5.093 bar；psi：73.87 psi；输出力：16,000 N；力放大倍数：16×For example, entering Input force N = 1000, Input piston diameter mm = 50, Output piston diameter mm (optional) = 200 in the Hydraulic Pressure Calculator gives: Pressure: 509.3 kPa; Bar: 5.093 bar; psi: 73.87 psi; Output force: 16,000 N; Force multiplication: 16×
哪些输入会被检查？Which inputs are validated?
「液压压力与输出力（帕斯卡原理）」会检查这些输入——「输入力 N」：必须填写，须大于 0，须为整数；「输入活塞直径 mm」：必须填写，须大于 0；「输出活塞直径 mm（可选）」：不能为负数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Hydraulic Pressure Calculator checks its inputs — "Input force N": required, must be greater than 0, must be a whole number; "Input piston diameter mm": required, must be greater than 0; "Output piston diameter mm (optional)": cannot be negative; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「液压压力与输出力（帕斯卡原理）」的设置：「输入力 N」默认 1000；「输入活塞直径 mm」默认 50；「输出活塞直径 mm（可选）」默认 200。每次生成结果都按当前设置处理。Settings in the Hydraulic Pressure Calculator — "Input force N" default 1000; "Input piston diameter mm" default 50; "Output piston diameter mm (optional)" default 200. The result always uses the current settings.
计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?
「液压压力与输出力（帕斯卡原理）」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The Hydraulic Pressure Calculator uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
