According to the automatic control and energy saving water pump set, automatic control and energy saving of agricultural irrigation and small-scale living water supply can achieved; through existing simple elements and change of the flow quantity and pressure in the water pipeline, the rotating speed of the motor can be adjusted automatically, and the purpose of energy saving is achieved; in addition, an integral compact structure is adopted.
Description
Technical field
The present invention relates to raw water service pump field, particularly relate to one and pour water for agricultural, the auto-control energy-saving water pump group of small-sized living water.
Background technique
China Patent No. is 201220610529.1 inventions disclosing that a key name is called " after variable frequency energy saving reforming motor-driven feed-water pump set mechanical system ", the invention provides motor-driven feed-water pump set mechanical system after a kind of variable frequency energy saving reforming, comprise the feed water pump, hydraulic couplers, feed water pump motor and the front-mounted pump that connect successively.Described feed water pump motor is connected with high voltage converter; Described front-mounted pump is connected with front-mounted pump motor; Described hydraulic couplers is connected with new oil-adding pump or newly-increased power frequency operation small motor.This invention by installing high voltage converter additional in original system, and the frequency modulation realizing feed water pump motor runs; By installing independently front-mounted pump motor additional to front-mounted pump, effectively can keep the delivery pressure of front-mounted pump, make it not by the impact of water supply pump motor rotating speed; By installing new oil-adding pump or newly-increased power frequency operation small motor additional to hydraulic couplers, solve the problem of the normal operation needs that cannot meet feed water pump group because water supply pump motor frequency control of motor speed runs the stoste coupling built-in fuel pump outlet low fuel pressure that causes, but this patent application is mainly used in the subsidiary engine of feed water pump as station capacity, structure and control more complicated, be not suitable for agricultural and small-sized living water.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of auto-control energy-saving water pump group, agricultural can be solved pour water, the auto-control energy-saving problem of small-sized living water, by simple existing element, with the flow in water lines and pressure change, the automation realizing motor speed regulates, and reaches energy-conservation object, and adopts the compact structure of integration.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of auto-control energy-saving water pump group, comprise base, base is provided with motor and water pump, the rotating shaft of motor is connected by shaft coupling with the rotating shaft of water pump, the top of motor and water pump is provided with operating console, and operating console and base form an entirety, operating console are provided with pressure control plate and frequency variator; Pressure control plate and pressure transmitter are connected to form as pressure control unit;
Water pump is connected with water pipe, water pipe is connected with pressure transmitter, the output port of pressure transmitter is connected with the input end of frequency variator, and the output port of frequency variator connects motor, and water pipe is communicated with effluent pipe mouth.
Operating console and base form an entirety by support, and floor installation is on support.
Auto-control energy-saving water pump group provided by the invention, the pressure of water outlet can be changed by the water-outlet quantity adjusted in water pipe, utilize pressure transmitter that corresponding signal is passed to frequency variator, thus the power supply frequency controlling motor changes rotating speed, by this simple control system, the rotating speed of self-regulation motor is realized according to water consumption, agricultural can be solved pour water, the auto-control energy-saving problem of small-sized living water, by simple existing element, with the flow in water lines and pressure change, the automation realizing motor speed regulates, and reaches energy-conservation object; Operating console and floor installation are integrated, and make pump group compact structure volume little.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Embodiment
As in Fig. 1, a kind of auto-control energy-saving water pump group, comprise base 10, base 10 is provided with motor 5 and water pump 3, the rotating shaft of motor 5 is connected by shaft coupling 4 with the rotating shaft of water pump 3, the top of motor and water pump is provided with operating console 6, and operating console 6 and base 10 form an entirety, operating console 6 are provided with pressure control plate 7 and frequency variator 8; Pressure control plate 7 and pressure transmitter 8 are connected to form as pressure control unit;
Water pump 3 is connected with water pipe 2, water pipe 2 is connected with pressure transmitter 1, the output port of pressure transmitter 1 is connected with the input end of frequency variator 8, and the output port of frequency variator 8 connects motor 5, and water pipe 2 is communicated with effluent pipe mouth 9.
Operating console 6 and base 10 form an entirety by support 11, and base 10 is arranged on support 11.
Working procedure of the present invention is as follows:
After the present invention starts to work, water pump 3 runs well under working pressure, the water consumption of needs is transferred to by outlet pipe by user, when water consumption strengthens, the pressure of effluent pipe mouth 9 diminishes, at this moment low-voltage signal is passed to frequency variator 8 by pressure transmitter 1, and frequency variator 8 changes the corresponding raising rotating speed of power supply frequency of motor 5;
Otherwise when water consumption reduces, the pressure of effluent pipe mouth 9 raises, and at this moment high-voltage signal is passed to frequency variator 8 by pressure transmitter 1, and frequency variator 8 changes the corresponding reduction rotating speed of power supply frequency of motor 5.By this simple control system, according to the rotating speed of water consumption self-regulation motor 5, reach the object of saving electric energy, and operating console 6 and base 10 are installed as one, make pump group compact structure volume little.
