Abstract
The utility model relates to a water supply and drainage device, in particular to a constant-pressure and variable-frequency water supply device. The existing constant-pressure and variable-frequency water supply device has the problems that the operation is unstable, the energy is not saved, the system maintenance is difficult and the like. Through the arrangement of a pressure sensor and full automatic variable-frequency control equipment on a water outlet of a water pump, the constant-pressure and variable-frequency water supply device provided by the utility model achieves the purposes of stable operation, energy saving and simple system maintenance.
Description
Technical field
The utility model relates to plumbing equipment, is specifically related to a kind of constant pressure frequency conversion water supply installation.
Background technology
At present the high-floor feedwater equipment of China has developed several stages, the constant pressure frequency conversion supply equipment that is supplied water and be most widely used till now by traditional roof water tank, and even popular again a kind of non-negative pressure water-supply installation now.Because the zone of non-negative pressure water-supply installation limitation and application limitation, still the constant pressure water supply equipment of present both economical practicality, thus how to make this equipment obtain better application, more stable operation, better energy-conservation, be the problem that each water pump producer need solve.
The variable frequency water supply product category is too many in the market, and manufacturer is quite a few, but the real realization producer of a complete set of equipment and few completely, and a lot of enterprises buy water pump and simply make a cover switch board then and control, just a cover a complete set of equipment at last.Can not guarantee that like this system is stable, also not have very good energy-saving effect, what high-floor feedwater was the most key undoubtedly is operation pressure stabilization, energy-conservation, consider its security significance to supplying water, system maintenance is simple, and fully automatic operation also is a necessary primary condition certainly.
Summary of the invention
It is a kind of stable, energy-conservation that the utility model provides, the simple fully-automatic constant pressure frequency conversion water supply facility of system maintenance.
The technical scheme that realizes the utility model purpose is:
A kind of constant pressure frequency conversion 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, is provided with the full-automatic frequency conversion control appliance that ac variable speed technology and Controlling Technique for Programming combine in the variable frequency control case.
Described variable frequency control case is connected with water pump by power cable.
Described water pump is the MODEL VERTICAL MULTISTAGE PUMP group.
The MODEL VERTICAL MULTISTAGE PUMP group is composed in parallel by a plurality of water pumps.
Full-automatic frequency conversion control appliance is responsible for the automatic control of whole water supply process, makes system stability, is responsible for the logic function that all water pumps switch.
The MODEL VERTICAL MULTISTAGE PUMP group is carried from low level water efficiently to a high position.
Pressure sensor is used to detect the actual pressure of user side, offering full-automatic frequency conversion control appliance feedback signal, thus the rising of control of pump rotating speed or reduction.
The utility model can replace water tower, high level cistern and traditional air pressure tank water supply installation, is applicable to the life and the production water supply of various types of water factories, pressurizing point, hotels, residential quarter contour level building.
The beneficial effects of the utility model are:
1, full-automatic frequency conversion control appliance; when system makes water; automatically start; when not making water, system stops automatically, and the system that can also realize guarantees the orderly closedown of system under the situation that low discharge leaks; thereby better protection water pump; make system operation safer, in system, stop for fear of the frequent starting of water pump.
2, product in the past much 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 does not just stop promptly automatically; this product addresses this problem fully; water pump does not detect automatically when having water, the time-delay autostop.
3, 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.
4, the very difficult resolution system low discharge of product in the past leaks and causes the non-stop-machine problem of system, makes system energy-conservation to greatest extent;
5, product in the past is when the big traffic demand of system, and when switching water pump, the system pressure fluctuation ratio is bigger, and this system has reduced this fluctuation at least 50% to greatest extent.

The specific embodiment
Fig. 1 and Fig. 2 have shown a kind of embodiment of the present utility model, a kind of constant pressure frequency conversion water supply installation, the MODEL VERTICAL MULTISTAGE PUMP group 2, pipeline, base plate 3 and the variable frequency control case 4 that comprise pressurized tank 1, compose in parallel by a plurality of water pumps, pipeline and pump group 2 are installed on the base plate 3, the water inlet of water pump connects the water source, pressurized tank 1 connects the delivery port of water pump, delivery port is provided with pressure sensor 5, be provided with the full-automatic frequency conversion control appliance that ac variable speed technology and Controlling Technique for Programming combine in the variable frequency control case 4, variable frequency control case 4 is connected with water pump by power cable.
Full-automatic frequency conversion control appliance is responsible for the automatic control of whole water supply process, makes system stability, is responsible for the logic function that all water pumps switch.
MODEL VERTICAL MULTISTAGE PUMP group 2 is carried from low level water efficiently to a high position.
Pressure sensor is used to detect the actual pressure of user side, offering full-automatic frequency conversion control appliance feedback signal, thus the rising of control of pump rotating speed or reduction.
The utility model can replace water tower, high level cistern and traditional air pressure tank water supply installation, is applicable to the life and the production water supply of various types of water factories, pressurizing point, hotels, residential quarter contour level building.
When the utility model makes water in system; automatically start; when not making water; system stops automatically; the system that can also realize guarantees the orderly closedown of system under the situation that low discharge leaks, thereby the better protection water pump makes system's operation safer; in system, stop for fear of the frequent starting of water pump.
