The variable-frequency constant-pressure water supply system is provided with a constant-pressure variable-frequency control system, a water pump and a pressure sensor, wherein the water pump is controlled by the constant-pressure variable-frequency control system, the pressure sensor is arranged on a pipe network and used for acquiring water pressure and water pressure change rate signals of the pipe network, and signals acquired by the pressure sensor are converted into electric signals which are transmitted to the constant-pressure variable-frequency control system. The variable-frequency constant-pressure water supply system is high-efficient and energy-saving, has energy increased along with reduction of flow, realizes stable water supply pressure and continuously variable flow in a large range and guarantees water utilization pressure of users due to constant-pressure water supply, is safe and sanitary as water for users is totally directly supplied via pipelines after the system realizes closed loop water supply, is automatic in operation and simple and convenient in management, prolongs service life of equipment and keeps a power grid stable.
Description
Technical field
The utility model relates to cloth staining technique field, the constant pressure water supply system that especially a kind of coloring system supplies water.
Background technology
Traditional way of supplying water mostly is pressurization and supplies water, general underground pressurized equipment and the high level cistern of adopting, or directly adopt underground pressurized equipment water rationing, because high level cistern can not be isolated fully with outside air, dust and other impurities enters easily, make that the water capacity is vulnerable to pollute, when using water rationing, because the pressure in the frequency-changing pressure stabilizing feedwater mode user pipe network is kept by pump, even configuration air pressure tank regulating power is also limited, causes water pump to work long hours like this, cause the hydraulic pressure instability that supplies water, and power consumption is higher, and supply equipment easily breaks down, troublesome poeration.
The utility model content
The technical problems to be solved in the utility model is: for the shortcoming that solves above-mentioned existence with not enough, a kind of constant pressure water supply system is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of constant pressure water supply system, have the constant pressure frequency conversion control system, by the water pump of constant pressure frequency conversion control system control be arranged on the pressure sensor of gathering its hydraulic pressure and variation in water pressure rate signal on the pipe network, the signal of pressure sensor collection is sent to the constant pressure frequency conversion control system after converting the signal of telecommunication to.
The beneficial effects of the utility model are, constant pressure water supply of the present utility model system, and energy-efficient, flow is more little, borrows energy big more; Constant pressure water supply has realized that systematic Water supply pressure is stable and flow can change on a large scale in continuously, and the assurance user uses water pressure; Safety and sanitation, after system carried out closed loop and supplies water, user's water was all directly supplied with by pipeline, operation, simple and convenient management automatically, and prolong equipment life, the protection stabilization of power grids.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, the constant pressure frequency conversion control system, 2, pressure sensor.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Structure principle chart as shown in Figure 1, a kind of constant pressure water supply system, have constant pressure frequency conversion control system 1, by the water pump of constant pressure frequency conversion control system 1 control be arranged on the pressure sensor 2 of gathering its hydraulic pressure and variation in water pressure rate signal on the pipe network, be sent to constant pressure frequency conversion control system 1 after the signal that pressure sensor 2 is gathered converts the signal of telecommunication to.
Before equipment puts into operation, set the pressure of supply water parameter as required, during the equipment operation, by hydraulic pressure in the pressure sensor 2 continuous acquisition water supply networks and variation in water pressure rate signal, and be converted into the signal of telecommunication and be sent to frequency-changing control system, control system is with the signal that feeds back and setting pressure compares and computing, if actual pressure is lower than setting pressure, then send the instruction control of pump and quicken operation, if actual pressure is than setting pressure height, then control of pump runs slowly, and when reaching setting pressure, water pump just maintains on this running frequency.If variable frequency pump has reached rated speed (frequency), through after the judgement of certain hour, if ductwork pressure still is lower than setting pressure, then control system can switch to power frequency operation with this water pump, and next water pump of variable frequency starting, reach setting pressure until ductwork pressure; Otherwise if the system water amount reduces, then the system command water pump runs slowly, behind the effective rotating speed that is reduced to water pump, the water pump that starts at first in the water pump that is then moving is out of service, promptly reduces the operation platform number of water pump, and is constant in the setting pressure scope until ductwork pressure.Main pump quits work, and auxiliary pump supplies water and also is the constant pressure water supply mode further to have improved operating efficiency, has saved the energy.
Little to the electrical network impact, defencive function is perfect.To the impact and the interference of electrical network, and apparatus control system has short circuit, overcurrent, overvoltage, overload, kinds of protect function such as under-voltage, overheated, improved operating efficiency greatly, prolonged the application life of water pump when having eliminated the pump motor across-the-line starting.When frequency converter breaks down, can be converted to power frequency operation automatically, it is uninterrupted to guarantee to supply water.Suddenly send a telegram here after having a power failure, equipment can start operation automatically again.The timing wake-up function.Because system is the platform number that how much decides the water pump that puts into operation according to the pipe network water supply volume, so when water supply volume for a long time in a certain certain water pump long-time running and the serious wear of will making when changing among a small circle, and other water pumps do not use to cause for a long time and get rusty, and then can address this problem easily after setting this function.For many water pumps,, must be provided with and regularly change pumping function for making each pump average operation time identical with flow.Set regularly change pumping function after, after a variable pump stream time surpasses setting value, and there is variable pump to be in " rest " state, then frequency converter automaticallyes switch and starts " rest " the longest variable pump of time, and stop former variable pump, guaranteeing each water pump operation time equalization, prolong water pump application life.Changing the pump time can set arbitrarily.
