Description
Technical Field
[0001] The utility model relates to the technical field of diesel generator equipment, in particular to a diesel generator air filter with high reliability. Background Technique
[0002] As an important standby power supply device, diesel generators are widely used in industrial, commercial and household fields. To ensure the normal operation of diesel generators, the performance of air filters is crucial. The main function of an air filter is to filter the air entering the diesel generator, remove dust, impurities and other particulate matters, and prevent these impurities from entering the engine interior, causing wear and damage. During the use of air filters in related technologies, problems such as loose filter element fixation and easy displacement often occur. Since diesel generators generate large vibrations and air flow impacts during operation, if the filter element cannot be firmly fixed, it is easy to cause the filter element to shift, thereby affecting the reliability of the air filter and even potentially leading to engine failures. In addition, the air filter lacks effective pressure monitoring means and cannot monitor the pressure difference between the inlet and outlet in real time, making it difficult to detect and handle abnormal conditions in the filtration system in a timely manner, affecting the reliability and safety of diesel generators. In view of this, it is necessary to improve the current air filter to solve the above problems.
[0003] The above information disclosed in this background technical section is only used to understand the background technology of the inventive concept, and therefore, it may include information that does not constitute prior art. Summary of the Utility Model
