Water system operation cost accounting method by utilizing software

Abstract

The invention provides a water system operation cost accounting method by utilizing software, comprising the steps of A, calculating the power consumption of a conveying unit medium; B, forming a logic relation curve and graph according to each value; C, establishing a graph for a conveying medium constant or inconstant pressure state system; D, calculating the water consumption of the conveying unit medium; and E, calculating artificial use costs, artificial maintenance costs and fitting purchase costs, and converting all the costs into the costs of the conveying unit medium. Compared with the prior art, the method is scientific, reasonable, and easy to implement, reduces workload and artificial work errors, more accurately manages water system costs, discovers problems in advance, and solves problems; the method is more conducive to cost reduction and safe production, provides data support for water system asset management and operation, and is more conductive to water system industry scientific management.

Description

technical field [0001] The invention relates to a method for calculating the operating cost of a water system by using software, which belongs to the field of water resources. Background technique [0002] At present, the water system accounts for a relatively large proportion of production costs, and some industries such as smelting, petrochemical, steel, tap water, power generation and other industries even account for more than 20%. Various industries will carry out cost accounting for water systems. At present, the operating costs of water systems include: electricity consumption, water consumption, maintenance labor and spare parts, and depreciation of fixed assets. [0003] At present, the cost accounting methods adopted by various industries are consistent: [0004] 1. Electricity consumption and water consumption are taken from on-site meter readings; [0005] 2. The cost of maintenance labor and spare parts is calculated according to the actual amount incurred; ...

AI Technical Summary

Problems solved by technology

[0004] 1. Electricity consumption and water consumption are taken from on-site meter readings;

[0005] 2. The cost of maintenance labor and spare parts is calculated according to the actual amount incurred;

[0011] 2. The final result needs to be counted and calculated manually, with a large amount of data, complicated work, and error-prone

[0013] 3. The final result is not accurate enough

[0014] The medium-term costs that account for the largest proportion of the water system’s operating costs, such as: the electricity and water costs of the transmission unit medium, are mainly completed by the power or metering department by reading the relevant metering instruments on the spot, and even in many industries and water use units are not accurate enough to the “transmission unit” Electricity and water charges of the medium", just copy the consumption of electricity and water charges of the relevant water system for a certain period of time (one month or one quarter)

In the end, users simply don't know how much it costs to transport a unit of medium (such as a ton of water)

[0015] 4. Problems cannot be detected in advance by the data reflected by the cost

[0016] First of all, the current cost statistics of water systems in various industries are not accurate enough, so there is no practical guidance for the optimization and maintenance of water systems
