Abstract
The utility model relates to a water supply-drainage device, in particular to a small intelligent water supply device. A traditional small water supply device has problems of unstable operation, no energy conservation and the like, the utility model adopts an integrated method and provides the small intelligent water supply device, and the device realizes the purposes of energy conservation and stable operation by arranging a pressure sensor and a five-way valve at the water outlet of a water pump.
Description
Technical field
The utility model relates to plumbing equipment, is specifically related to a kind of small intelligent water supply installation.
Background technology
At present, in small-sized water supply field, it is a lot of to use converter technique to carry out the product category of energy-conservation supercharging on the market, but technical level differs greatly, much just rest on the simple energy-conservation or simple steady pressure, do not reach one at all and make water system not only steady pressure but also energy-conservation good product.Particularly in the high gear sub-district, villa, there is higher quality requirements bath centers etc. to this product especially: energy-conservation, environmental protection, all steel water conservancy parts, pressure stability, simple to operate, volume is little, stable performance.
Because be the household application market in feedwater field, cost is the problem that we will solve certainly, and we can not add a lot of peripheral controllers as main equipment, such as: controller, PLC etc., cost will inevitably be very high like that.
Small-sized on the market variable frequency water supply product just simply utilizes the inside PID function of frequency converter at present, increase by 1 water flow switch during installation in the water side, as there is when opening valve water to flow, frequency converter will start water pump, and valve closing does not then have current, and frequency converter will stop water pump, but like this along with the frequent starting of valve or stop, frequency converter stops frequent driving starting mode of pump, and this damages motor easily, and the build-up of pressure instability.
Summary of the invention
The utility model adopts integrated method, reduces the hardware investment cost, makes that product is maximized to reach stable, purpose of energy saving.
It is a kind of stable, energy-conservation that the utility model provides, economic small intelligent water supply installation.
The technical scheme that realizes the utility model purpose is:
A kind of small intelligent water supply installation, comprise pressurized tank, water pump, pipeline, base plate and variable frequency control case, pipeline and water pump are installed on the base plate, the water inlet of water pump connects the water source, pressurized tank connects the delivery port of water pump, delivery port is provided with pressure sensor and five-way valve, is provided with full-automatic frequency conversion control appliance in the variable frequency control case.
Described five-way valve is noiseless check five-way valve.
Pressure sensor detects the actual pressure of user side, offering the control system feedback signal, thus the rising of the rotating speed of control of pump or reduction.
Noiseless check five-way valve prevents water pump when stopping, and the backflow of water and minimizing are to the impact of water pump.
Full-automatic frequency conversion control appliance is responsible for the automatic control of whole process, makes system stable.
The beneficial effects of the utility model are:
1, product in the past all is to shut down by the sleep mode of frequency converter itself; in view of water pump under the in fact a lot of situations of characteristics of water pump water conservancy curve does not enter resting state; so water pump is autostop not just, this product addresses this problem fully, water pump time-delay autostop when not having water.
2, product in the past can only just can be realized excessive low water level protection to water pump by the switch signal that connects in the water tank; this product addresses this problem fully; its internal junction Heshui pump water conservancy curve and water pump operation situation; automatically judge whether lack of water of water pump; reach automatic protection functions, also have float for water tank switching signal defencive function simultaneously concurrently.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Fig. 1 has shown a kind of embodiment of the present utility model, a kind of small intelligent water supply installation, comprise pressurized tank 1, water pump 2, pipeline, base plate 3 and variable frequency control case 4, pipeline and water pump 2 are installed on the base plate 3, the water inlet of water pump 2 connects the water source, pressurized tank 1 connects the delivery port of water pump 2, and delivery port is provided with pressure sensor 5 and noiseless check five-way valve 6, is provided with full-automatic frequency conversion control appliance in the variable frequency control case 4.
Noiseless check five-way valve 6 prevents water pump 2 when stopping, and the backflow of water and minimizing are to the impact of water pump 2.
Full-automatic frequency conversion control appliance is responsible for the automatic control of whole process, makes system stable.
