Description
Technical field
The utility model relates to a kind of water system, particularly a kind of intelligent pressure regulating water system.
Background technology
Traditional frequency conversion constant pressure water supply system comprises water pump assembly, be connected and be connected to back with water inlet line and water supply line with water pump assembly, be connected with pressure meter on water supply line, pressure meter and programmable logic controller PLC join, programmable logic controller PLC and frequency converter join, and frequency converter and water pump assembly join.At water low-valley interval, terminal pressure is superfluous, produces energy waste, increases the possibility of leak rate and booster.And adopt end constant voltage mode to need sensor installation endways, if user's end-to-end distance from water supply point away from; be difficult to set up data transmission link, and need long-term line upkeep expense, also have the problems such as communication time delay.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, not only can regulate water supply capacity by pressure signal, also can regulate water supply capacity according to the flow signal of water, in the situation that guaranteeing adequate water supply not only energy-conservation but also safety, reduce the leakage of water facilities, the intelligent pressure regulating water system that improves service life of equipment, overcomes the deficiencies in the prior art.
Intelligent pressure regulating water system of the present utility model, comprise water pump assembly, be connected with water pump assembly and be connected to back with water inlet line and water supply line, on water supply line, be connected with pressure meter, pressure meter and programmable logic controller PLC join, and programmable logic controller PLC and frequency converter join, frequency converter and water pump assembly join, water supply line is provided with flow meter, and flow meter and programmable logic controller PLC join, and programmable logic controller PLC is connected with man-machine interface touch-screen.
Intelligent pressure regulating water system of the present utility model, by frequency converter (being RHVC), control water pump assembly, according to flow, pressure signal, carry out PID closed-loop adjustment, first water pump assembly is to fill water compared with low cruise water supply line, according to pressure signal, with minimum setting pressure, carry out constant voltage control again, after pressure of supply water is stable, by flow signal, obtain the real-time water situation of user, the pressure of supply water that pressure compensation regulates water pump assembly is carried out in the head loss that calculates pipeline, realizes end water water pressure invariableness.System architecture is simple, utilizes pressure signal and flow signal to regulate the water supply capacity of water pump assembly simultaneously, and energy-saving safety, reduces the leakage of water supply line, improves application life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1: 1 is water pump assembly, be connected with water pump assembly 1 and be connected to back with water inlet line 2 and water supply line 6, on water supply line 6, be connected with pressure meter 8, pressure meter 8 joins with programmable logic controller PLC 4, programmable logic controller PLC 4 and frequency converter 3(RHVC) join, frequency converter 3 joins with water pump assembly 1, flow meter 7 is installed, for the discharge on quantative water supply pipeline 6 on water supply line 6.Flow meter 7 joins with programmable logic controller PLC 4, and programmable logic controller PLC 4 is connected with man-machine interface touch-screen 5.
Intelligent pressure regulating water system of the present utility model, by frequency converter (being RHVC), control water pump assembly, according to flow, pressure signal, carry out PID closed-loop adjustment, first water pump assembly is to fill water compared with low cruise water supply line, according to pressure signal, with minimum setting pressure, carry out constant voltage control again, after pressure of supply water is stable, by flow signal, obtain the real-time water situation of user, the pressure of supply water that pressure compensation regulates water pump assembly is carried out in the head loss that calculates pipeline, realizes end water water pressure invariableness.System architecture is simple, utilizes pressure signal and flow signal to regulate the water supply capacity of water pump assembly simultaneously, and energy-saving safety, reduces the leakage of equipment, improves application life.
Owing to increasing flow meter in original constant pressure water supply system, be used for Real-Time Monitoring water situation, water supply network is conventionally comparatively complicated, cannot calculate head loss by theory, according to pipe network situation, select some pressure temporary pressures monitoring point to record each pressure constantly, by obtaining the head loss under each water supply volume to the contrast conting of synchronization flow and each pressure spot, finally set up Mathematical Modeling, according to water situation, adjust pressure of supply water and realize virtual end constant pressure water supply.After Mathematical Models, temporary pressure monitoring point is dismountable, and the problem that has not also had data to spread out of at a distance and safeguard responds and there is no time delay fast according to water situation.By gathering electric weight, automatically add up water supply unit consumption, calculate in real time water application efficiency.Unit water application efficiency can reflect processing while reducing in time, guarantees that unit is always in efficient operation.Water supply volume sudden change early warning, by with historical same period water supply volume compare and can find in time that water supply network misses.If occurred, pipeline explosion is reported to the police immediately by the comprehensive judgement of pressure versus flow or stoppage protection is avoided larger loss.
