Generally speaking, users will select a fan with an appropriate air volume according to the actual working conditions. In order to ensure that the fan can smoothly enter the normal working state and meet the required air volume requirements, it is necessary to be cautious and meticulous when selecting the fan. However, if it is found that the fan does not achieve the expected usage effect during the process of using the fan, what should be done?

First of all, we need to understand various situations that may cause the problem of insufficient air volume of the high-pressure centrifugal fan, as well as the corresponding solutions. The details are as follows:

Problems related to the pipeline:
Pipeline leakage: If it is found that the insufficient air volume is caused by pipeline leakage, then the leaking pipeline needs to be repaired in a timely manner. First, the specific location of the leakage can be determined, and then according to the material of the pipeline and the leakage situation, an appropriate repair method can be selected, such as welding, using sealant, or replacing the damaged pipeline components, etc., to ensure the tightness of the pipeline and reduce the air volume loss.
Too long pipeline: When the pipeline is too long, it will increase the resistance of air flow in the pipeline, thus affecting the air volume output of the fan. At this time, the pipeline needs to be reasonably set again. Consider shortening the length of the pipeline, optimizing the pipeline route, and reducing unnecessary elbows and resistance components to reduce the resistance of air flow, improve the working efficiency of the fan, and make the air volume meet the expected requirements.

Problems with the impeller and lubrication:
Impeller wear and excessive clearance: Impeller wear and excessive clearance may affect the air volume of the fan. In this case, it is necessary to check whether the oil supply system is working normally, check whether there is a situation of insufficient oil supply, and supplement the oil quantity according to the actual situation. At the same time, it is also necessary to check the wear degree of the impeller. If the wear is relatively serious, it may be necessary to repair or replace the impeller to restore its normal working performance.
Poor lubrication: Poor lubrication will increase the friction between the fan components, affect the operation efficiency of the fan, and then lead to insufficient air volume. At this time, it is necessary to clean the oil filter, remove the impurities and dirt in the filter, and ensure the cleanliness of the lubricating oil. At the same time, clean and check the drip nozzle to ensure that the lubricating oil can drip into the lubrication part normally, providing good lubrication conditions for the normal operation of the fan.

Problems with the filtration system:
Filtration blockage: If the inlet filter of the high-pressure centrifugal fan is blocked, it will hinder the normal entry of air and lead to a decrease in air volume. In response to this situation, the filter needs to be cleaned in a timely manner. According to the instructions for using the filter, it can be disassembled, cleaned with a suitable cleaning agent to remove the dust, impurities and other blockages on the filter, and then dried and reinstalled in place to restore the normal filtering function of the filter and ensure the smooth air intake of the fan.

Problems with the belt drive:
The belt is too loose and the rotation speed drops: If the fan uses a belt drive method, when the belt is too loose, it will cause the friction between the belt and the pulley to decrease, thus making the rotation speed of the fan drop, and then affecting the air volume. At this time, the tension of the belt needs to be adjusted. By adjusting the distance between the pulleys or using a tensioning device, the belt can reach an appropriate tension degree to ensure that the fan can operate at a normal rotation speed and output a sufficient air volume.
