Abstract
The water system of the manual constant pressure of band that the present invention is provided is made up of changeable water supply controller, manual automatic transfer switch, automatic outletting pressure sensor, manual water outlet pressure sensor, frequency converter and supply-water pump, be it is characterized in that：Manual automatic transfer switch is connected with automatic outletting pressure sensor, manual water outlet pressure sensor, changeable water supply controller and frequency converter respectively, changeable water supply controller is connected with automatic pressure sensor, manual automatic transfer switch and frequency converter respectively, frequency converter is connected with changeable water supply controller, manual automatic transfer switch, manual water outlet pressure sensor and supply-water pump respectively, and supply-water pump is connected with frequency converter.The invention has the beneficial effects as follows, when changeable water supply controller breaks down, it is impossible to when realizing automatic running, manually can also realize constant-pressure operation, it is ensured that pressure of supply water is stable, it is not necessary to which operator on duty scene is on duty.
Description
Technical field
The present invention relates to a kind of water system, specifically a kind of water system with manual constant pressure.
Background technology
At present, in society, water system typically all adopts Automatic Constant-pressure Water Supplying System, when changeable water supply controller breaks down, when cannot realize automatic running, the power frequency operation of water pump can only manually be realized, pressure oscillation is big, needs personnel on site on duty on duty, it is impossible to which realizing also can constant-pressure operation under manual mode.
Content of the invention
In view of the deficiency that above-mentioned prior art is present, the water system of the manual constant pressure of the band that the present invention is provided, when changeable water supply controller breaks down, when cannot realize automatic running, constant-pressure operation manually can also be realized, it is ensured that pressure of supply water is stable, it is not necessary to which operator on duty scene is on duty.
The technical solution adopted for the present invention to solve the technical problems is：Water system with manual constant pressure is by changeable water supply controller, manual automatic transfer switch, automatic outletting pressure sensor, manual water outlet pressure sensor, frequency converter and supply-water pump composition, manual automatic transfer switch respectively with automatic outletting pressure sensor, manual water outlet pressure sensor, changeable water supply controller is connected with frequency converter, changeable water supply controller respectively with automatic pressure sensor, manual automatic transfer switch is connected with frequency converter, frequency converter respectively with changeable water supply controller, manual automatic transfer switch, manual water outlet pressure sensor is connected with supply-water pump, supply-water pump is connected with frequency converter.
The invention has the beneficial effects as follows, when changeable water supply controller breaks down, it is impossible to when realizing automatic running, manually can also realize constant-pressure operation, it is ensured that pressure of supply water is stable, it is not necessary to which operator on duty scene is on duty.
Description of the drawings
Principle assumption diagram of the accompanying drawing 1 for the present invention.
In figure, 1, changeable water supply controller, 2, manual automatic transfer switch, 3, automatic outletting pressure sensor, 4, manual water outlet pressure sensor, 5, frequency converter, 6, supply-water pump.
Specific embodiment
Water system with regard to the manual constant pressure of 1 pair of band of the invention of accompanying drawing makees following detailed description of below.
As shown in Figure 1, the water system of the manual constant pressure of band of the invention is by changeable water supply controller（1）, manual automatic transfer switch（2）, automatic outletting pressure sensor（3）, manual water outlet pressure sensor（4）, frequency converter（5）And supply-water pump（6）Composition, manual automatic transfer switch（2）Respectively with automatic outletting pressure sensor（3）, manual water outlet pressure sensor（4）, changeable water supply controller（1）And frequency converter（5）It is connected, changeable water supply controller（1）Respectively with automatic pressure sensor（3）, manual automatic transfer switch（2）And frequency converter（5）It is connected, frequency converter（5）Respectively with changeable water supply controller（1）, manual automatic transfer switch（2）, manual water outlet pressure sensor（4）And supply-water pump（6）It is connected, supply-water pump（6）With frequency converter（5）It is connected.
Under normal circumstances, manual automatic transfer switch is got to automated location, the discharge pressure signal of changeable water supply controller collection automatic outletting pressure sensor transmission, the pressure set according to controller itself and the discharge pressure of collection carry out PID arithmetic, control frequency converter frequency, so as to control the rotating speed of water pump, constant pressure supplying water is finally realized.
When changeable water supply controller breaks down, manual automatic transfer switch is got to manual position, the discharge pressure signal of frequency converter collection manual water outlet pressure sensor transmission, PID arithmetic is carried out according to the discharge pressure that frequency converter itself sets pressure parameter and collection, control frequency converter frequency, so as to control the rotating speed of water pump, manual constant pressure water supply is finally realized.
It should be noted that, above example is only in order to illustrating technical scheme and unrestricted, although being described in detail to the present invention with reference to above-described embodiment, still technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should cover in the middle of scope of the presently claimed invention.
