Problems solved by technology

In the follow-up design of other similar engineering projects, the design institute did not get timely feedback from the previous owner, or the owner did not carry out single-item measurement of equipment energy consumption, lacking more accurate equipment energy consumption data, so the design institute will Simply copy the design, so that there is a strange circle of empirical design, but the current status of the actual operation of the fan site is that the efficiency is low and the energy consumption is high year after year
[0003] Especially for fan systems with relatively constant working conditions, because the design parameters calculated according to the requirements of the design specifications are generally conservative, the opening of the fan inlet valve during actual operation is generally below 50%, and the actual operating performance of the fan seriously deviates from The design point is exceeded, and the actual operating efficiency deviates from the high-efficiency area. Therefore, it is urgent to carry out in-service energy-saving transformation for this type of fan system.

Abstract

The invention discloses a rapid selection method, device and apparatus for an in-service remanufacturing design scheme of a fan apparatus, and aims to solve the problem that energy-saving return of investment cannot be maximized due to resource waste caused by the fact that a complete machine replacement mode is usually adopted during energy-saving transformation of existing fan equipment running in service. According to calculation and analysis of the difference percentage of the two operation data of the fan flow and the fan static pressure and the design parameters, the design scheme for in-service remanufacturing of the fan apparatus is rapidly determined through a table look-up method, and the design scheme for energy-saving transformation of the fan apparatus can be visually, clearly and rapidly obtained. And a direction is pointed out for a next drawing design interface, the maintenance cost of fan equipment is saved, and energy-saving return on investment is maximized.

Description

technical field [0001] The invention belongs to the technical field of in-service remanufacturing of fluid equipment, and in particular relates to a method, device, equipment and storage medium for quickly selecting an in-service remanufacturing design scheme of fan equipment. Background technique [0002] Most of the fans used in foreign projects are completed by auxiliary machine manufacturers. Due to the reasonable selection and moderate air volume and pressure margin, the efficiency of the fans is relatively high; while domestic fan applications are selected and configured by the factory design institute. Due to the lack of actual operation experience, the design parameters are conservative. The maximum air volume and maximum air pressure under the most unfavorable conditions of the system are used as the basis for selection and design. The auxiliary machine factory, fan manufacturer, and design institute all have allowances for fan parameters , so after putting into ope...
