The working principle of the tank-pump integrated variable-frequency non-negative-pressure water supply system comprises the following specific steps:
the tank-pump integrated variable-frequency non-negative-pressure water supply system disclosed by the utility model is combined with municipal pipe network pressure change and system flow, water pump rotating speed, pump set real-time power consumption and other data to realize linkage control of the water supply system. By adopting the field RS485 bus communication and accurate control mode, the requirements of municipal pipe network protection, reasonable switching between water supply of the water tank and municipal non-negative pressure water supply, real-time updating of water quality in the water tank and stable, energy-saving and reliable operation of the system are met.
The tank-pump integrated variable-frequency non-negative-pressure water supply system monitors and controls the change conditions of water flow and water pressure in real time, and sends instructions to a variable-frequency water pump (13A) in real time by a digital integrated variable-frequency controller 17A in a digital communication mode. There are several operating modes:
(1) increased water usage operation process
When the water consumption of a user is increased, the pressure of a water supply system and the pressure of the most unfavorable water point (such as the water supply pressure of the highest floor which is farthest away from a water pump room in a high-rise building) need to be met, and the energy consumption of a single water pump is higher than that of two water pumps, at the moment, the digital integrated frequency conversion controller 17A can automatically control the whole pump unit to operate in the most energy-saving mode after carrying out contrastive analysis according to various data (including the water consumption, the required pressure, the operation data of the single pump, the operation data of parallel pumps and the like). The new starting pump and the operated water pump are subjected to asynchronous control adjustment, the gentle change of water consumption and pressure is ensured, and finally synchronous operation is achieved, and the stability of the system is ensured.
(2) Water consumption reduction operating process
When the water consumption of a user is reduced, the rotating speed of the water pump can be adjusted along with the change of water flow by the running variable-frequency water pump, and the variable-frequency water pump can feed back a signal to the water pump variable-frequency module by the sensor to control the rotating speed of the water pump to be reduced. At this moment, when the special controller for the water pump (namely the digital integrated frequency conversion controller 17A) analyzes that one pump can be reduced and still meet the water supply requirement, the digital integrated frequency conversion controller 17A activates the pump reduction function, the analysis is carried out according to the running time of the water pump 13A, the water pump 13A with the longest running time can be decelerated, other water pumps 13A are slowly and synchronously accelerated, whether the asynchronous mode is adopted to verify that the system can meet the requirement of reducing the running of one water pump 13A or not is verified, and if not, the system can automatically stop the pump reduction function. If the water consumption requirement of a user can be met, the decelerated water pump 13A can quit operation in a frequency conversion soft stop mode (in the frequency conversion process, the rotating speed of the water pump is gradually reduced, and the water pump is slowly stopped, namely soft stop), and other water pumps 13A synchronously start to operate to ensure the stability of the system.
(3) The system is in the small flow mode operation process
When the water consumption continuously drops, after the single pump is operated, the system judges whether the single pump is below 20% of the system through the control and monitoring functions, and then activates the small-flow sleep shutdown mode, and when the system is verified to be in the small-flow mode, the digital integrated frequency conversion controller 17A can reduce the rotating speed of the water pump.
If the basic water supply requirement of the user cannot be met, the digital integrated frequency conversion controller 17A feeds back a signal to the water pump, so that the water pump stops the small-flow sleep shutdown mode and recovers to the previous running mode; if the basic water supply requirement of a user can be met, the digital integrated frequency conversion controller 17A can control the water pump 13A to increase the rotating speed of the water pump, the pressure signal fed back by the water pump 13A is adjusted to the shutdown sleep pressure (higher than the set pressure), and after the outlet end air pressure water tank 15A reaches the set pressure value, the water supply system of the water pump 13A automatically sleeps and shuts down.
In the non-negative pressure water supply process of the equipment, a pressure sensor (a water inlet pressure sensor 5A) at the water inlet part monitors the input pressure of a municipal water supply pipe network at the front end in real time. When the municipal water supply network pressure is abnormal, the digital integrated variable frequency controller 17A controls the water inlet electric valve 6A at the water inlet pipe to be closed and simultaneously opens the water outlet electric valve 7A on the water outlet pipe of the stainless steel water storage tank 9A, the water pump 13A absorbs water from the stainless steel water storage tank 9A, and the digital integrated variable frequency controller 17A controls the water inlet electric valve 6B to be in an open state to supplement water for the stainless steel water storage tank 9A. When municipal pipe network pressure detection resumes normal value, the digital integrated variable frequency controller 17A control is opened intake motorised valve 6A and is closed the play water motorised valve 7A on the stainless steel storage water tank 9A outlet pipe simultaneously, and water pump 13A resumes the full variable frequency water supply mode of operation of municipal administration.
In order to avoid the aging phenomenon caused by long-time water storage of the stainless steel water storage tank 9A, the water storage time in the stainless steel water storage tank 9A exceeds 8 hours, the hydraulic water level control valve 8A and the water inlet electric valve 6A of the water inlet pipe are closed, and the closing or opening of the hydraulic water level control valve 8A is automatically controlled by the water level. The water pump 13A absorbs water by the stainless steel storage water tank 9A frequency conversion pressure boost and supplies the user side, when the stainless steel storage water tank 9A water level drops to the minimum value that sets for, opens the motorised valve of intaking 6A on the inlet tube, closes the motorised valve of going out of water 7A on the stainless steel storage water tank 9A outlet pipe, and the water pump 13A resumes to absorb water from municipal pipe network full frequency conversion no negative pressure water supply operation.
When the system operates, when the pressure sensor (the water inlet pressure sensor 5A) of the water inlet detects that the pressure of the water pipe is lower than a limited pressure value specified by a local water service company, a pressure signal is fed back to the digital integrated variable frequency controller 17A, the digital integrated variable frequency controller 17A can start the municipal pipe network pressure protection function, and the opening of the water inlet electric valve 6A at the inlet end and the compensation function (the water inlet electric valve and the pipe network are integrally laminated to eliminate negative pressure, remove secondary pollution and intelligently compensate the water flow) of the stainless steel flow stabilizing tank 21A are controlled and adjusted, so that the pressure is not lower than the pressure value specified by the water service company. If the flow and the pressure do not reach the limit value of the water service company, the digital integrated variable frequency controller 17A automatically closes the water inlet electric valve 6A at the non-negative pressure water supply water inlet position, and the water pump 13A changes the stainless steel water storage tank 9A to absorb water, change the frequency and pressurize the water to supply to a user end.
When the water consumption is extremely small, the air pressure water tank 15A can maintain the normal water supply of the system, meanwhile, the air pressure water tank 15A is favorable for keeping the stability of the working pressure of the system when the water pumps 13A are switched with each other, and under special conditions, the air pressure water tank 15A can eliminate the water hammer phenomenon (namely, in a pressure pipeline, the flow rate of water changes suddenly due to certain external reasons, such as that a valve is closed suddenly and a water pump unit stops suddenly, so that the water hammer hydraulic phenomenon is caused).
And a water inlet electric valve II 6B is arranged at the front section of the hydraulic water level control valve 8A of the water inlet of the stainless steel water storage tank 9A of the equipment and is used for emergency closing under the condition of overflow alarm of the stainless steel water storage tank 9A, so that the economic loss caused by a flooding accident in a pump room is prevented.
In conclusion, the tank-pump integrated variable-frequency non-negative-pressure water supply system can save construction cost, improve water safety, reduce secondary pollution of water quality and achieve the purpose of saving energy and reducing consumption by utilizing part of municipal water supply pressure.
