Description
Technical Field
The invention relates to water supply equipment, in particular to variable pressure water supply equipment with high-level energy storage and intelligent sensing functions.
Background
In the eighties, the gravity water supply mode of the roof water tank adopted by tap water is generally applied by the advantages of high energy storage and water supply efficiency and stable water pressure, but the water supply mode also has the following two defects: firstly, because the roof water tank is communicated with the atmosphere, the secondary pollution of water quality is easy to cause. Secondly, because the water tank on the top of the building is used for supplying water by gravity, the water pressure for residents in the top zone is low.
In the nineties, in order to overcome the defects, a roof water tank is removed, and water is supplied by a variable-frequency constant-pressure mode, so that the problem of the roof water tank is solved, and the problem of low water supply efficiency is caused. In order to solve the problem, an air energy storage tank is usually configured at the water outlet end of the variable-frequency constant-pressure water supply equipment, when the water pump stops with water valley and small flow, compressed air in the energy storage tank extrudes water in the tank to realize uninterrupted water supply, and the water pump is restarted to supply water and simultaneously store energy again until the pressure in the energy storage tank is reduced to the lower limit of the water supply pressure. When the water supply is carried out in a low-rise building, the contradiction between the water supply efficiency and the volume of the energy storage tank is not quite outstanding, but when the water supply is carried out in a high-rise building, the volume of the energy storage tank needs to be increased by times to maintain the same water quantity under the condition of the same water supply pressure difference, and the pressure bearing grade of the energy storage tank is correspondingly improved.
At present, the tap water pressurized water supply equipment installs an air energy storage tank on one floor or the negative floor because: first, the initial product configuration of a pressurized water supply facility is habitually retained and is habitually natural. Secondly, if the energy storage tank is installed at the top end of the building, corresponding installation building space is needed. In the existing 'design code for water supply and drainage of buildings', the description of the air pressure energy storage tank is the component parts of water supply equipment, and the air pressure energy storage tank is arranged in a water pump room on one floor or one floor below the ground, and the corresponding building structure and the pipeline design are the same. That is, from product to design, the pneumatic energy storage tank is installed together with the water pump, which is consistent with the performance of the water supply equipment product. The fundamental reason is that the problems of the existing air pressure energy storage tank are not sufficiently known.
At present, the volume of the air energy storage tank arranged at the water outlet end of the equipment is generally 0.06-3.53m for reasons of cost and installation space3If the water supply pressure range is 0.9-1.0MPa, the corresponding pressure difference is 0.1 MPa, the energy storage expansion water supply volume is only one tenth of that of the whole tank body, namely 0.006-0.353 m3. The air pressure tank widely used at present has the advantage that the higher the water supply pressure is, the smaller the energy storage regulating water supply amount is under the condition of the same volume according to P1V 1= P2V 2. The traditional water supply equipment needs to start the water pump 5 times in one hour under the water supply condition of the air pressure energy storage tank of 0.9-1.0 Mpa.
