Start from volume and time 先确认容积和时间
Use the real chamber volume and required pump-down time, not only the machine size. 应输入真实有效容积和目标抽气时间，而不是只看设备外形尺寸。

Sizing calculator 选型计算
Estimate Required Pumping Speed 估算所需真空泵抽速
This tool gives a first-pass sizing result. Final pump selection should also check gas load, leakage, vapor, dust, duty cycle, voltage and installation conditions. 这个工具用于初步估算。最终选型还需要结合漏气量、气体负载、水汽粉尘、工作周期、电压和安装条件一起复核。

How to Use This Vacuum Pump Calculator 如何使用这个真空泵选型计算器
Check target pressure 确认目标真空度
A lower target pressure usually needs more pumping speed and a suitable pump type. 目标压力越低，通常对抽速和泵型匹配要求越高。
Keep K traceable 保持 K 值可追溯
Use K = 1.2 for preliminary sizing unless your engineer confirms a different correction factor. 初步估算默认使用 K = 1.2；如需改动，应由工程师确认修正系数。
Need final selection? 需要最终选型？
Send Your Result and Working Conditions 发送计算结果和工况信息
For formal quotation, please also share voltage, frequency, duty cycle, gas condition, existing pump model and destination country. 正式报价前，请同时提供电压频率、工作周期、气体情况、现有泵型号和目的国家。
