Abstract
The utility model relates to an electricity-saving device of a frequency-conversion voltage constant water supply equipment, belonging to an electricity saving device. One end of a fluid sensor is connected with a pressure energy storage tank and a control module is connected respectively with a water source sensor, a frequency controller, the fluid sensor, a teletransmission pressure gauge on the pressure energy storage tank and a pressure gauge with welded joint. The electricity-saving device has the advantages that the utility model has a novel structure and the working characteristic completely meets the demand of constant pressure water supply and constant pressure of the pipe network. Besides, the utility model having high automation realizes the aim of unmanned watch, electricity saving, reducing the wear of the equipment and prolonging the service life.
Description
Technical field
The utility model belongs to a kind of battery saving arrangement, especially is applied in the constant pressure water supply equipment.
Background technology
At present, small-sized tap water equipment generally adopts constant pressure water supply equipment, its advantage be along with the water supply volume of tap water pipe network what, the rotating speed of the frequency converter automatically controlled water pump of supply equipment supplies water, and reaches economize on electricity, and equipment attrition is little, noise is low, the purpose of stable water pressure; Its shortcoming is, pipe network is at water low ebb or night not during water, and the pressure of supply water of pipe network is kept by pump rotary speed, and equipment has certain electric weight waste, also has equipment to waste wearing and tearing, drawbacks such as useless noise.
Summary of the invention
The utility model provides a kind of battery saving arrangement of constant pressure water supply, and to solve pipe network at water low ebb or night not during water, the equipment of existence has certain electric weight waste, wastes problems such as wearing and tearing, useless noise.The scheme that the utility model is taked is: an end of fluid sensor is connected with the air pressure energy storage canister, control module respectively with water source sensor, frequency-variable controller, fluid sensor, air pressure energy storage canister on the teletransmission pressure meter be connected with electro connecting pressure gauge.
Operating principle: the other end of fluid sensor is connected with the output of water pump group, behind the device start, constant pressure water supply when control module obtains the water-flow signal of fluid sensor.When control module can not get the water-flow signal of fluid sensor, control module control frequency converter increased output, made the air pressure energy storage canister reach water pump stall behind the upper limit pressure.The pressure of water supply network is kept by the pressure of air pressure energy storage canister, and realizes that low discharge supplies water.Along with user's water, when ductwork pressure is lower than the threshold pression of air pressure energy storage canister, control module control frequency converter starts pump operation, make ductwork pressure reach constant pressure point, at this moment, if pipe network does not have water, control module can not get the water-flow signal of fluid sensor, control module control frequency converter and water pump increase output, make the air pressure energy storage canister reach upper limit pressure after, the water pump stall is kept water supply by the air pressure energy storage canister.So move in circles, thus constant pressure water supply when reaching water, and the water pump stall is supplied water by energy storage canister during unmanned water.Control appliance quit work when control module can not get the lack of water signal of water source sensor.
The utility model has the advantages that: the constant pressure water supply that novel structure, its operating characteristic satisfy pipe network fully requires and a small amount of water and ductwork pressure requirement on duty.Reach the automaticity height, realize unmanned, at utmost realize economize on electricity reducing equipment attrition, prolong the purpose of service life of equipment.

The specific embodiment
Referring to Fig. 1, on the basis of existing constant pressure water supply equipment, the water source is passed device 1 to be connected with equipment water pump 2, fluid sensor 7 is connected between water pump flap valve 4 and pressure energy-storage jar 9 and the pipe network outlet, control module 8 is gathered the signal of telecommunication of water source sensor 1, fluid sensor 7, electro connecting pressure gauge 5 teletransmission pressure meters 6, by the duty of control frequency converter 3 behind the sequential operation.This control module adopts plc, Siemens JS7-200 series.
This control module program circuit is referring to Fig. 2.
