An energy-saving intelligent water pump using variable frequency control

Abstract

The invention provides an energy-saving intelligent water pump utilizing frequency converting control, and belongs to the technical field of water pumps. The energy-saving intelligent water pump utilizing frequency converting control comprises a pump body and a motor connected with the pump body. A shell of the pump body is provided with a box body, a frequency converter is arranged in the box body, the frequency converter is connected with the motor, and the frequency converter can change the work current of the motor and control the revolving speed of the motor. A flow velocity probe is arranged at the water outlet position of the pump body, the flow velocity probe is connected with an IC chip, the IC chip is arranged in the box body, and the IC chip is connected with the frequency converter and is used for controlling the frequency converter. When the water level is low and the flow velocity probe detects that the lower flow velocity is small, a flow velocity signal is transmitted to the IC chip, and a work signal is sent to the frequency converter after the flow velocity signal is analyzed through the IC chip, the frequency converter controls the current of the motor to enable the work current of the motor to get smaller and the revolving speed to be reduced, so that the water yield can be adjusted according to the water level condition, normal water output is guaranteed, and energy waste caused by too high lift is avoided.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to an energy-saving intelligent water pump controlled by frequency conversion. Background technique [0002] Water is the root of human existence, and water is the lifeblood of agriculture. my country is a country with many people, little land, water shortage and frequent natural disasters. Agricultural irrigation water accounts for more than 80% of the country's total water use, while China's total water resources account for about 7% of the global total, and the per capita water resources are only a quarter of the world's average level. It is listed by the United Nations as 13 water-deficient one of the countries. China needs to use 7% of the world's water to maintain the production and life of 22% of the population. Among the 517 cities in the country, more than 300 cities lack water. my country is also a large agricultural country, and agriculture is a large water user. T...
