Water pump motor

Water pump motor can be widely used in different fields, in addition to flammable, explosive or corrosive gas occasions. Such as transportation, mixing, printing, agricultural machinery. It can also be used with machine tools, pumps, blowers, compressors and other supporting equipment. The pump and motor are connected by an elastic coupling.

Water pump motor Power calculation method

P = pgQH/(n1n2)
Where: P — power, W; P = density of water, p=1000 kg/m^3; G — Acceleration of gravity, g=9.8m/s^2; Q — flow rate, m^3/s; H — head, m; N1 — pump efficiency; N2 — Motor efficiency.

Water pump motor Experiment

On June 2, 2010, the Ministry of Finance and the National Development and Reform Commission jointly issued the Notice on Printing and Distributing the Implementation Rules for the Promotion of High-efficiency Motors of energy-saving Products benefiting the People project, which included high-efficiency motors into the implementation scope of energy-saving products benefiting the people project and promoted them in the form of financial subsidies.
While developing high-efficiency motors, adopting frequency conversion speed regulation technology is another effective energy-saving measure [1]. High-efficiency motor and variable frequency motor test put forward higher requirements on the function and performance indexes of test equipment. In order to accurately obtain the efficiency of the motor, a broadband power analyzer with microprocessor and a variable frequency power transmitter/sensor with high accuracy level should be used.
