Problems solved by technology

In this case, the working condition of the fan is that the speed is constant, but the working environment temperature range will be very wide, from -40 degrees to 60 degrees. At present, it is impossible to determine the remaining life of the fan.

Embodiment Construction

[0024] refer to figure 1 As shown, a method for determining the remaining life of a fan includes the following steps:

[0025] S1, obtain the corresponding relationship between the life of the fan and the temperature of the working environment of the fan;

[0026] S2, divide the working environment temperature of the fan into multiple temperature ranges, and convert the expected life L of the fan corresponding to each temperature range according to the corresponding relationship between the life of the fan and the working environment temperature of the fan;

[0027] S3, obtaining the working time of the fan in each temperature range;

[0028] S4, according to the corresponding relationship between the life of the fan and the working environment temperature, the working time of the fan in each temperature range is converted into the working time at the rated temperature;

[0029] S5, determining the remaining lifetime of the fan working at the rated temperature.

Abstract

The invention discloses a method for determining residual life of a fan. The method comprises the following steps that S1, the corresponding relation between the fan life and the fan working environment temperature is obtained; S2, the fan working environment temperature is divided into a plurality of temperature zones, and the fan expected life L corresponding to the temperature zones is converted according to the corresponding relation between the fan life and the fan working environment temperature; S3, the working time of the fan in each temperature zone is obtained; S4, according to the corresponding relation between the fan life and the fan working environment temperature, the working time of the fan in each temperature zone is converted to the working time at the rated temperature;and S5, the residual life of the fan working under the rated temperature is determined. According to the method, the customer can be reminded to replace the fan in time after the residual life of thefan reaches a set value, accidental faults of the fan are prevented, and great loss caused by system accidental shutdown which may occur is avoided.

Description

technical field [0001] The invention relates to a fan, in particular to a method for determining the remaining life of the fan. Background technique [0002] In the industrial inverter system, due to the harsh external working environment and large temperature changes, the fan is often a weak point in the life of the system. The current technical method is mainly used to judge whether the fan is damaged, but it cannot tell the user how long the fan can run in real time, so that the fan cannot be replaced in time after the failure, resulting in unnecessary losses. [0003] The existing technology also determines the remaining life of the fan according to the fan speed, but usually for the situation where the operating temperature of the fan is basically constant and the speed is variable, if the ambient temperature changes greatly and the fan speed is uncontrollable, it cannot be applied. For example, the speed of industrial fans cannot be controlled. In this case, the work...
