Through above -mentioned scheme, move hush air under the normal condition and fold and press energy -saving pump group, cut off the water or hush air folds when pressing energy -saving pump group trouble immediately that the original water supply mode of automatic switch -over to building supplies water when the running water delivery pipe, can not be anhydrous available immediately because of the trouble, when running water water pressure just often the automatic switch -over fold to hush air and press energy -saving pump group to move, circulated original water supply equipment of building and cistern, the saving electric energy of maximize again of set phase.
Description
Technical field
This utility model relates to supply equipment field, refers in particular to a kind of mute type wisdom overlapping frequency changing constant pressure energy-saving water supply system.
Background technology
The increase pipe network pressure-superposed non-negative-pressure variable frequency energy-saving pump group feed pipe original with building that secondary water-supply reducing energy consumption company currently on the market is single is in parallel, MODEL VERTICAL MULTISTAGE PUMP group that building are original to be carried, frequency-conversion control cabinet, cistern are stopped using, when tap water cut-off just the most anhydrous available, this reducing energy consumption mode has three drawbacks:
1, the original vertical multi-stage pump of building for a long time need not, bearing, water pump occur become rusty dead situation, when time to be used, be difficult to the most normally start.
2, original pump variable frequency switch board because of for a long time need not, electric component performance easily occur degenerate, when time to be used, be difficult to the most properly functioning.
3, the original cistern of building because of for a long time need not, water quality deterioration is to not using.
Based on this, it has been proposed that a kind of constant pressure water supply system based on PLC, including cistern, water supply network, water pump assembly and PLC, described cistern is for storing the water inlet of city planting ductwork, water in cistern is supplied end user by water pump assembly by described water supply network, described water pump assembly includes the water pump of multiple stage parallel running, described PLC passes through Frequency Converter Control pump operation, described water system is additionally provided with the pressure transmitter for detecting water supply network hydraulic pressure, and described pressure transmitter sends pressure signal to PLC.
But, this water system still there is problems in that the noise of water pump is too big, and power consumption is the highest.Thus, how to propose a kind of mute type wisdom overlapping frequency changing constant pressure energy-saving water supply system, become the problem needing in the industry solution badly.
Utility model content
The utility model proposes a kind of mute type wisdom overlapping frequency changing constant pressure energy-saving water supply system, in order to solve the problems referred to above.
The technical solution of the utility model is achieved in that
A kind of mute type wisdom overlapping frequency changing constant pressure energy-saving water supply system, including: the secondary pressing pump group that the cistern that control module is connected with tap water supply pipe is connected with described cistern, described secondary pressing pump group end connects usingwater network, and the mute type stacking energy-saving pump group in parallel with described cistern, secondary pressing pump group, described control module is electrically connected described cistern, secondary pressing pump group and mute type stacking energy-saving pump group.
Further, described control module is additionally provided with time control unit.
Further, described secondary pressing pump group includes at least one main pump and an auxiliary pump, described main pump and described auxiliary parallel connection of pumps.
Further, described usingwater network is provided with pressure transmitter, and described pressure transmitter electrically connects described control module.
The beneficial effects of the utility model are: pass through such scheme, run mute type stacking energy-saving pump group under normal circumstances, when tap water supply pipe is cut off the water or can automatically switch to the original water supply pattern of building i.e. secondary pressing pump group during mute type stacking energy-saving pump group fault immediately and cistern supplies water, will not be the most anhydrous available because of fault, automatically switch to mute type stacking energy-saving pump group run when tap water hydraulic is normal, both the periodic cyclic original supply equipment of building and cistern, the most maximized saves energy.
