Abstract
The utility model provides a constant-pressure concentrated water supply system of a solar water heater, which relates to the technical field of constant-pressure water supply. The constant-pressure concentrated water supply system of the solar water heater comprises a solar water heater, a water storage tank of hot water, water supply power devices and a user terminal which are sequentially connected. The constant-pressure concentrated water supply system of the solar water heater is characterized in that the water supply power devices are N water pumps arranged in parallel, and at least one water pump of the water pumps is a variable-frequency water pump. A pressure detection device is arranged on a user master pipeline of the user terminal and is a pressure sensor. The system makes full use of the property of the variable-frequency water pump, realizes the real-time regulation of water supply pressure and also lowers the investment cost furthest.
Description
Technical field
The utility model relates to the constant pressure water supply technical field, specifically a kind of solar water heater constant voltage central water supply system.
Background technology
Along with the emergence of new forms of energy, the increasing architectural solar water heater of having installed.The water system of common solar water heater is all carried out adherence pressure by water pump, and this water system can not realize constant pressure water supply, and water system is had certain impact when starting.
The utility model content
The purpose of this utility model is to provide a kind of solar water heater constant voltage central water supply system, realizes the purpose of constant pressure water supply, farthest reduces cost of investment simultaneously.
The technical scheme in the invention for solving the technical problem is: this kind solar water heater constant voltage central water supply system, comprise the solar water heater, hot water storage tank, water supply power set, the user terminal that connect successively, it is characterized in that, described water supply power set are N the water pump that is set up in parallel, and wherein at least one water pump is a variable frequency pump.
On user's total pipeline of described user terminal, pressure-detecting device is set.
Described pressure-detecting device checkout gear is a pressure sensor, by near the pipeline pressure signal the closed-loop control system collection user terminal, water pump and variable frequency pump is controlled.
The beneficial effects of the utility model are: native system has made full use of the characteristic of variable frequency pump, use variable frequency pump that water system is carried out trickle adjusting, only need a variable frequency pump simultaneously, all the other water pumps are all common water pump, when realizing regulating pressure of supply water in real time, farthest reduced cost of investment.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Among the figure: 11 first users, 12 second users, 13 the 3rd users, 2 pressure sensors,
3 solar water heaters, 4 hot water storage tanks.
The specific embodiment
As shown in Figure 1, this kind solar water heater constant voltage central water supply system comprises the solar water heater 3, hot water storage tank 4, water supply power set, the user terminal that connect successively.
The water supply power set are N the water pump that is set up in parallel, and first water pump wherein is a variable frequency pump 1, the so-called water inlet that is meant all water pumps that is set up in parallel is connected to the hot water storage tank, the delivery port of all water pumps is connected to user's total pipeline, user terminal is a plurality of, be labeled as first user 11, second user 12, the 3rd user 13 respectively, be parallel-connected to user's total pipeline.
On user's total pipeline of user terminal pressure sensor 2 is set, this pressure sensor is electrically connected to control system, by near the pipeline pressure signal the closed-loop control system collection user terminal, water pump and variable frequency pump is controlled.Concrete regulative mode is: under the situation that does not have user's water, all water pump closures make the rated pressure that remains on design in user's total pipeline; When the user begins water, variable frequency pump is at first started working, reduction along with user's total pipeline internal pressure, variable frequency pump increases output gradually, when the maximum output of variable frequency pump can not satisfy under the situation of user's water, open second water pump, control system is regulated variable frequency pump simultaneously, makes the pressure in user's total pipeline remain on certain numerical value.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (3)
