粘度計(jì)轉(zhuǎn)子轉(zhuǎn)速對(duì)照表常數(shù)和圖片
閱讀:3570 發(fā)布時(shí)間:2022-10-24對(duì)于未知樣品的粘度測量,首先應(yīng)估算樣品的粘度值。再選擇相對(duì)應(yīng)的幾組轉(zhuǎn)子、轉(zhuǎn)速組合來進(jìn)行測量。當(dāng)估計(jì)不出被測流體的大致粘度值時(shí),應(yīng)假定該樣品的粘度值較高,用由小到大(體積)的轉(zhuǎn)子和由慢到快的轉(zhuǎn)速進(jìn)行測試。
粘度測量的原則是:
高粘度的流體選用?。w積)的轉(zhuǎn)子、慢轉(zhuǎn)速;
低粘度的流體選用大(體積)的轉(zhuǎn)子、快轉(zhuǎn)速;
各型號(hào)轉(zhuǎn)子與轉(zhuǎn)速的組合所對(duì)應(yīng)的測試范圍可參照下表:
