The sinking pump mute type direct connection secondary water supply device has the beneficial effects of being small in structural size and low in cost, saving energy and the like; in addition, the sinking pump mute type direct connection secondary water supply device is flexible in installation, convenient to install, less in occupied land and low in noise; the sinking pump can be installed in the vertical mode, the horizontal mode or the lateral mode; a special pump room is not needed, so that application of the sinking pump mute type direct connection secondary water supply device to a secondary water supply system will have the good practical value and the good popularization prospect.
Description
Technical field
The present invention relates to secondary water-supply technical field, specifically the direct-connected secondary water-supply equipment of a kind of submersible pump squelch type.
Background technology
Along with highrise building gets more and more, secondary water-supply is more prevalent, traditional arrange pond, water tank secondary water-supply mode due to exist take up an area large, invest high, installation and maintenance trouble, there is the problem such as energy dissipation and water pollution hidden danger and be cancelled gradually pond, water tank direct-connected secondary water-supply mode substitute, but existing direct-connected secondary water-supply mode great majority adopt to arrange the structure such as steady flow compensator, vacuum suppresser, its complex structure, cost is high, and also there is the problem that noise disturbs residents when being installed in residential building basement.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, cost is low, easy for installation, take up an area less, the direct-connected secondary water-supply equipment of submersible pump squelch type that noise is low.
The technical solution adopted for the present invention to solve the technical problems is: the direct-connected secondary water-supply equipment of submersible pump squelch type is primarily of shell, submersible pump, auto-pneumatic cylinder, flow detector and switch board composition, described submersible pump is installed in described shell, and shell and submersible pump are prepared, shell import is connected with distribution pipe by water inlet tube connector intakes, shell outlet is connected water outlet by water outlet tube connector with outlet pipe, described distribution pipe is connected with tap water water inlet pipe, and on described tap water water inlet pipe, backflow preventer is housed, tap water water inlet pipe was equipped with strainer before backflow preventer, it is supply water with water spot that described outlet pipe is connected with grid, described distribution pipe is provided with pressure detecting table one, in order to detect tap water intake pressure, described outlet pipe is provided with pressure detecting table two, in order to detect its discharge pressure, and on described outlet pipe, described auto-pneumatic cylinder and flow detector are also housed, described auto-pneumatic cylinder is in order to voltage stabilizing and eliminate water hammer, described flow detector is in order to detect the water supply flow of water pipe, described pressure detecting table one, submersible pump, pressure detecting table two and flow detector are connected with described switch board wiring separately respectively, to realize automatic water-supply and protection.
Operating principle of the present invention is, be arranged on submersible pump in shell directly to be fetched water pressurization from tap water water inlet pipe by distribution pipe, it is supply water with water spot that its water outlet is flowed to grid by outlet pipe, when pressure detecting table one detects the low pressure values of tap water intake pressure lower than systemic presupposition, submersible pump is by automatic shutdown protection and avoid affecting the suction and pumping of tap water water inlet pipe, eliminate pipe network negative pressure, when pressure detecting table one detect tap water intake pressure higher than systemic presupposition high pressure values and above time, submersible pump will start and normal water supply automatically, with the requirement of satisfied water spot to the water yield and hydraulic pressure.
Because submersible pump is built in shell, make its structural volume little, but also have shielding Noise Reduction, when submersible pump works, its noise is minimum reaches 25 decibels ~ 40 decibels.
The invention has the beneficial effects as follows, the present invention has the advantages such as structural volume is little, cost is low, energy-conservation, and it is flexible for installation, convenient, take up an area few, noise is low, submersible pump can adopt mode that is vertical, horizontal or side formula to install, and without the need to arranging special pump house, thus in secondary water supply system, application will have good practical value and promotion prospect.
