The worshiper thinks that the worst is the insufficient horsepower. 崇拜者认为最坏的事是马力不足。
For medium and larger horsepower sizes, some manufacturers elect to offer by-pass (pumpage cooled) jacketed motor designs. 对于大中型功率(马力)的电机,一些制造商选择提供旁路(泵冷却)加套电机设计结构。
Horsepower (hp) is a unit of measurement of power (the rate at which work is done). There are many different standards and types of horsepower. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied between geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1, 2010, the use of horsepower in the EU is permitted only as a supplementary unit.
