Description

A kind of many pumps multifrequency chamber type intelligent non-negative pressure water-supply installation
Technical field
The utility model belongs to water intaking, catchment or the technical field of the device of water distribution or the application of method, particularly a kind ofly with many frequency converters, controls one by one each water pump with the more stable many pumps multifrequency chamber type intelligent non-negative pressure water-supply installation that meets different water supply requirements.
Background technology
Conventionally our said non-negative pressure water-supply installation, generally refers to non-negative pressure frequency-changing water supply device, is also variable frequency non-negative pressure water, is the supercharging equipment being directly connected on water supply network.Traditional way of supplying water be unable to do without reservoir, and the general running water pipe of water in reservoir is supplied with, and becomes zero after having like this water of pressure to enter pond, causes a large amount of energy to waste.
And non-negative pressure water-supply installation is a kind of desirable energy-saving water supply equipment, it utilizes the pressure of city planting ductwork, and water system directly absorbs water and supplies with user's water supply unit on city planting ductwork; Take safeguard measure; guarantee that pipe network does not produce negative pressure; guaranteeing that city planting ductwork supplies water under impregnable prerequisite; utilize city planting ductwork overbottom pressure to supply water; save the energy consumption of supply equipment, and there is the plurality of advantages such as totally-enclosed, pollution-free, occupation of land amount is little, quick for installation, reliable, easy to maintenance.
Non-negative pressure water service system is applied more and more in present urban water supply, has played the effect of good energy conservation.Wherein, pot type non-negative pressure water service system is the water system generally adopting, its operating principle is directly from pipe network, to absorb water under the situation allowing at ductwork pressure, utilize the pressure of city planting ductwork, energy conservation, when non-negative pressure water service system water absorption is less than pipe network water supply ability, can't cause the reduction of ductwork pressure, but in the water use peak period, when the water absorption of water pump is greater than pipe network water supply amount, municipal ductwork pressure reduces, cause flow straightener internal pressure also to reduce accordingly, when the pressure of flow straightener is brought down below atmospheric pressure, the negative pressure preventer on steady flow compensator top is opened, water pump absorbs water in flow straightener, now flow straightener and atmosphere are communicated with, be equivalent to a little water container.With this understanding, non-negative pressure water service system can not utilize the pressure of supply water of pipe network, and after the water in flow straightener is sucked, unit will be had to reduce output and even be cut off the water, and after waiting ductwork pressure to increase, equipment could utilize remaining pressure of piping system normal water supply.As can be seen here, pot type non-negative pressure water service system in use, require city planting ductwork can meet the output of pot type non-negative pressure water service system when the water of peak, make flow straightener internal pressure higher than atmospheric pressure, otherwise probably will cut off the water, affect user's normal water, this is very inconvenient for common water user, more cannot be used in and for continuing to supply water, has in the occasion of high requirements and have potential safety hazard.
Thus, in a lot of occasions, box type negative-pressure-free water system has stronger environmental suitability, particularly during water use peak, by computer controlled variable device adjusting frequently water pump, can, by the water pressurized water supply in airtight water tank, avoid the flow because of the required feedwater of user of city planting ductwork undersupply.Yet; in prior art; for assure feed water; often more than one, water pump in box type negative-pressure-free water system; and frequency converter in switch board often only has one; i.e. many water pumps of a Frequency Converter Control; although this has reduced user's burden from cost; but in actual use, buried hidden danger; especially when frequency converter breaks down; be at least that many water pumps are shut down simultaneously and do not worked and cause user's water breach, yet be more even likely many water pumps high-frequency works and cause the paralysis of city planting ductwork simultaneously.
