Description
Technical field
The utility model relates to supply equipment, is specially a kind of supply equipment that can realize pressure control and variable frequency control.
Background technology
At present, the traditional supply equipment of living water use mainly contains two kinds, and a kind of is to place water tank on the roof, utilizes water pump that water is injected water tank, and the delivery port of water tank links to each other with user's water supply pipe, utilizes the water level pressure difference that tap water is flowed to the user; Another relies on the supply equipment of air pressure control, and its method of operation is to come controlled pressure by pressurized tank and pressure switch, and then control water supply state.
More than two kinds of supply equipments obvious defects is arranged: though first kind of supply equipment is cheap, the water tank that the roof is placed causes the secondary pollution of water easily, and the bad control of pressure of supply water; Second kind of supply equipment control mode is fairly simple, but the pressure of supply water deviation ratio is bigger, can shorten the life-span of water pump and motor greatly.
The utility model content
The technical problem that the utility model solved is to provide the constant pressure frequency conversion supply equipment, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
The constant pressure frequency conversion supply equipment comprises variable frequency control cabinet, some water pump assemblies, pressurized tank, pressure sensor, low water level sensor and water supply network.
Described water pump assembly is made up of water pump, flap valve and ball valve (perhaps butterfly valve), each water pump assembly all links to each other with switch board by lead, described pressurized tank is installed in an end of water pump assembly outlet conduit, pressure sensor is installed on the outlet conduit, pressure sensor links to each other with switch board by data wire, described low water level sensor is installed on the pipeline between water pump assembly and the pond, and is communicated with switch board.
In addition, the utility model is set up flow transmitter on the outlet conduit of water supply network when joining the low-capacity pump system, and flow transmitter is communicated with the variable frequency control cabinet.
Beneficial effect: the utility model has solved low hydraulic pressure problem, has avoided the secondary pollution of water, can keep the water supply network constant pressure, has prolonged the application life of water pump and motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 structural representation of the present utility model, comprise variable frequency control cabinet 1, some water pump assemblies 2, pressurized tank 3, pressure sensor 4, low water level sensor 6 and water supply network 7, because the constant pressure frequency conversion supply equipment has assembled low-capacity pump in the present embodiment, so also comprise flow transmitter 5.
In the present embodiment, the utility model is provided with 4 water pump assemblies 2, water pump assembly 2 adopts parallel way work, each unit is made up of water pump 21, flap valve 22 and butterfly valve 23, each water pump assembly 2 all links to each other with variable frequency control cabinet 1 by lead, variable frequency control cabinet 1 can regulate automatically certain water pump and rotating speed or many water pumps drop into withdraw from use.
Pressurized tank 3 is installed in an end of water pump assembly 2 outlet conduits, in order to regulate the pressure of whole water supply network, and directly supply water for pipe network, on the pipeline between pressurized tank 3 and the water pump assembly 2, pressure sensor 4 is installed, pressure sensor 4 links to each other with variable frequency control cabinet 1 by data wire, can gather at any time water supply network 7 pressure, and with data delivery to variable frequency control cabinet 1.
Low water level sensor 6 is installed on the intake duct of water supply network 7, just on the pipeline between pond 8 and the water pump assembly 2, low water level sensor 6 also is to link to each other with variable frequency control cabinet 1 by data wire, water level in the pond 8 is transferred to variable frequency control cabinet 1 at any time, when pond 8 middle water levels are reduced to setting value, variable frequency control cabinet 1 can cut off water pump 21 power supplys, prevents water pump 21 idle running, damages motor.
The utility model realizes that pressure controling mode is: before starting device, at first on variable frequency control cabinet 1, set a starting pressure value, when the pressure of water supply network 7 during greater than setting value, pressurized tank 3 can directly supply water, if start water pump 21 when water supply network 7 pressure equal to set value, water pump 21 ductwork pressures in service reach and stop water pump 21 operations when stopping pressure, water pump 21 starts the back ductwork pressure and surpasses starting pressure, do not reach water pump 21 continuation operations when stopping pressure, when ductwork pressure did not reach starting pressure yet after water pump 21 full speed runnings, variable frequency control cabinet 1 can be controlled the water pump assembly 2 that does not start and append startup.
The utility model realizes that the variable frequency control mode is: at system's detected pressure in outlet pipeline place during less than the starting pressure value of water pump 21, variable frequency control cabinet 1 can be regulated water pump 21 rotating speeds automatically, make outlet pressure constant, water pump 21 reaches power frequency rotating speed operation but pressure when not reaching setting pressure, and variable frequency control cabinet 1 appends the water pump assembly 2 that startup is not worked; Along with water supply volume reduces, outlet pressure rises, and the rotating speed of water pump 21 can reduce gradually, if water pump 21 speed drops are low to moderate the minimum speed that system is provided with, variable frequency control cabinet 1 will stop water pump operation successively.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
