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
The invention belongs to pump technology field, relate in particular to a kind of energy-conserving intelligent water pump that adopts VFC.
Background technique
Water is the root of human survival, and water is agriculture lifeblood.China be people many, less, the country of lack of water, frequent natural calamity.Agricultural irrigation water accounts for the more than 80% of national water total amount, and water resources in china total amount accounts for 7% of global total amount, and water resources is 1/4th of world's per capita share per capita, and united state classifies one of 13 lack of water countries as.China maintains production and the life of 22% population with 7% water in the world.In 517 cities, the whole nation, there is more than 300 urban water shortage, China is again a large agricultural country, agricultural is water rich and influential family, annual agricultural irrigation water amount approximately 3500 billion cubic meters, due to water resources deficiency, the annual area suffered from drought of China's agricultural reaches hundred million mu of 2-3, grain reduces approximately 2.5 hundred million kilograms, and industrial output value reduces 1,200 hundred million yuan.Along with China's economy develops rapidly, water resources problems is day by day serious.
Jet pump is to utilize the transformation of fluid flow energy to reach the object of conveying, utilizes it can carry liquid, also can carry gas.According to working fluid used, be generally divided into vapor pump and water jet pump two classes, jet pump simple structure, easy to use.Water jet pump is divided into again Ordinary Centrifugal Pumps and self-priming injection pump, and Ordinary Centrifugal Pumps, if suck liquid level under impeller, should be poured water when startup in advance, very inconvenient.For water in pump, suction pipe import need to fill bottom valve, and when pump work, bottom valve causes very large hydraulic loss.Self-priming injection pump does not need to pour water exactly before startup, through short-time running, by the effect of pump itself, water can be drunk up, and drops into and normally works.
Water pump of the prior art only has a kind of operating current, lift all sets in the time dispatching from the factory, and cannot change in actual applications, also just cannot need to regulate lift according to the actual water level depth, be a kind of waste for the energy in the course of the work, cannot reach energy-conservation object.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and forms simply, the energy-conserving intelligent water pump of the employing VFC that operating cost is low.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of energy-conserving intelligent water pump that adopts VFC, the motor that comprises the pump housing and be connected with the pump housing, one casing is installed on the shell of the described pump housing, in described casing, be provided with a frequency variator, described frequency variator is connected with motor, change the operating current of motor by frequency variator, control the rotating speed of motor, at the water outlet of the described pump housing, one flow velocity probe is installed, described flow velocity probe is connected with IC chip, described IC chip is arranged in casing, and described IC chip is connected with frequency variator, be used for controlling frequency variator, in the time that water level is more shallow, flow velocity probe detects water velocity hour, this flow velocity signal is transferred to IC chip, after IC chip analysis, give working signal of frequency variator, the electric current of Frequency Converter Control motor, the operating current of motor is diminished, rotating speed reduces, thereby adjust the water yield according to water level situation, ensure normal water outlet, do not waste energy because lift is too high.
Described flow velocity probe is installed along the diametric(al) of pump housing water outlet, and measuring accuracy is high, easy for installation.
Described casing is arranged on the top, rear portion of motor, regulates the counterweight of motor, makes more to stablize in the course of the work.
On described IC chip, be also connected with an alarm, in the time that motor is normally worked, when flow velocity probe detects non-water flow, flow velocity probe is to signal of IC chip, and IC chip is reported to the police by alarm, reminds staff to switch off the pump.
The invention has the beneficial effects as follows: structural design advantages of simple of the present invention, adopt frequency conversion control technique, make the water pump can be according to the actual water level depth, self-regulation motor size of current, controls pump speed then, ensures normal water outlet, does not waste energy because lift is too high.
