水煞車式動力計
Froude INC. 的F
系列水煞車動力計具有結構緊湊、工作穩定可靠以及易於維修的設計特點。動力計安裝在兩個聯軸器上，而聯軸器有通過轉子將潤滑油噴射到傳動軸上。這套標準的機器就在潤滑過的耳軸承上運轉。
動力計的工作機件由許多專門設計的澆鑄在不鏽鋼轉子和定子上的半圓形葉片組成，水在這些葉片周圍產生環形渦流式流動，而發動機外殼產生反作用力扭拒，並通過負荷測力機構來阻止其轉動從而產生讀數。測功機的負荷由液壓伺服系統驅動蝶形閥進行出水或進水控制。發動機產生的能量被測功機吸收，並以熱量的形式被水帶走。
主要特徵:
-
動力計額定轉速時的扭矩測量精度為±0.25%
-
速度測量精度為±1 RPM
-
伺服負荷控制
-
響應速度快
-
運行穩定
-
可靠性高
-
易於維修
