Problems solved by technology

The strength of the water tank can be effectively increased through the spherical void, but at present, when calculating the retained water volume of the water tank, it is usually directly multiplied by the water level of the water tank and the longitudinal sectional area of ​​the water tank without the spherical void, without considering the corresponding water volume of the spherical void, resulting in the calculation There is usually an error of about 5% in the amount of retained water, which is not conducive to the precise control of the water supply of the water tank

Embodiment 1

[0035] This embodiment provides a calculation method for the reserved water volume of the secondary water supply tank. Generally speaking, the stored water volume in the water tank includes two parts. The amount of water in the spherical part is set as the second amount of water; the sum of the first amount of water and the second amount of water is the actual retained water amount in the water tank. Based on this, the specific calculation process of this scheme is as follows:

[0036] First calculate the first water volume of the water tank except for the spherical section and the second water volume of the water tank belonging to the spherical section, and then calculate the actual remaining water volume in the water tank according to the sum of the first water volume and the second water volume; The first water volume is obtained by multiplying the water level height of the retained water volume by the longitudinal section area of ​​the water tank without the spherical gap....

Embodiment 2

[0062] On the basis of Example 1, this example uses cross-sectional dimensions such as figure 1 The tank shown is further described with specific data, as follows:

[0063] Set the length, width and height of the water tank to 4m, 2m and 2m respectively, and the total volume without the spherical gap is 16m 3 , the longitudinal sectional area S of the water tank without the spherical gap is 8m 2 , the water tank has 2 layers, and the height of each layer is H 0 is 1m, the number of protruding balls in each layer of water tanks is 12, the height h of the ball is 0.12m, the radius r of the bottom of the ball is 0.4m, and the distance a from the lowest point of the ball to the lowest point of the layer is 0.1m.

[0064] At a certain moment, the water level height Y of the water tank is measured as 1.732m, and the retained water volume corresponding to the water level height Y is W, then:

[0065] W=W 1 +W 2 (1)

[0066] W 1 =Y·S=1.732m×8m 2 =13.856m 3 (2)

[0067] W ...

Abstract

The invention discloses a method for calculating the reserved water volume of a secondary water supply tank. Firstly, the first water volume of the water tank except for the spherical section and the second water volume of the water tank belonging to the spherical section are respectively calculated, and then according to the first water volume and the second The sum of the water volumes can be used to obtain the actual stored water volume in the water tank; the calculation method of the second water volume is: first divide the water level height of the stored water volume into multiple types according to the height of the water surface layer where the stored water volume is located, and calculate for each The formula used to calculate the second water volume is determined according to the type, and then the second water volume is calculated according to the corresponding calculation formula. The invention can calculate the actual retained water volume of the water tank according to the actual situation on the side of the water tank, thereby ensuring the accuracy of calculating the retained water volume of the water tank and providing guarantee for accurately controlling the water supply of the water tank.

Description

technical field [0001] The invention relates to the field of secondary water supply of urban water supply pipe network systems, in particular to a method for calculating the reserved water volume of a secondary water supply tank. Background technique [0002] Secondary water supply refers to the way of supplying water to users or self-use through pipelines through storage, pressurization and other facilities when the water pressure and water volume requirements of civil and industrial buildings exceed the capacity of urban public water supply or self-built water supply pipe network . The secondary water supply facilities mainly include three parts: water storage equipment, pressurization equipment and pipelines. The specific water supply process is: after the tap water is sterilized in the water plant, it is first transported to the secondary water supply and storage equipment (hereinafter referred to as the water tank) through the urban pipe network system. , and then deli...
