The invisible soul of air compressor operation-air filter

Air filter, also known as air filter. In the entire air compressor operating system, all components are indispensable, but air filters are often ignored by users. In fact, air filters can be called the invisible soul in the design and operation of the air compressor system.

　　 In the various failures of the air compressor, such as high temperature, running oil, abnormal noise of the main engine, stuck main engine, damaged bearings, coking of lubricating oil, and flat suction hoses, the culprit is often the air filter.

　　 One, the influencing factors of air filtration

　　If the air filter quality is not good, it will cause the following effects:

　　1 The quality of lubricating oil is degraded

　　The air filter has poor filtration accuracy, which will cause a large amount of dust to enter the lubrication system, resulting in a decrease in the quality of the lubricating oil, which will affect the rotor, bearings and other core components of the main machine, resulting in a reduction in the efficiency of the main machine and a shortened life.

　　 2 oil content clogged

　　 The air compressor oil separation system is more sensitive to lubricant impurities. Increased lubricant impurities will cause the oil to be clogged and greatly reduce the efficiency of the oil. If the clogging reaches a certain level, it will cause the oil to deform. The most direct consequence is that the system runs seriously.

　　3 oil filter clogged

　　The main function of the oil filter is to maintain the quality of lubricating oil. However, due to the poor quality of the air filter, the burden on the oil filter will increase significantly. After the oil filter is seriously clogged, the most direct problem of the machine is high temperature.

　　4Inlet pressure difference increases, increasing energy consumption

　　 If the quality of the air filter is not good, it will increase the pressure difference before and after the intake air, thereby reducing the efficiency of the system. The most direct manifestation is that the connecting hose is deflated.

To sum up, due to the quality of air filter, it will cause problems such as high temperature of the machine, oil running, etc., and will also cause the main engine overhaul cycle to be greatly shortened, lubricating oil coking and other problems. What is more serious is that the energy saving of air compressors The energy consumption of the air compressor has increased significantly. It will also greatly shorten the maintenance cycle.

From the perspective of comprehensive operating costs, the selection of high-quality air filters will greatly reduce the overall operating costs, avoid unnecessary maintenance cycles, machine damage and other losses. In front of space, it is not worth mentioning.

　　 2. The quality of air filter

　　 Air filter generally distinguishes the quality from the following aspects.

　　1) Waterproof performance

　　The filter paper should have excellent waterproof performance. The poor waterproof performance of the filter paper will accelerate the clogging of the air filter.

　　2) Filtration accuracy and filtration area

　　 High-efficiency filter material and professionally designed fiber structure can effectively ensure the filtration accuracy and filtration area, and ultimately extend the service life of the air filter.

　　3) High-quality housing and seals

　　 High-quality housing and seals can ensure the rigidity and compressive strength of the air filter itself, as well as a reliable seal under changes in ambient temperature.

　　4) Ash capacity

　　The filter paper with a large ash capacity can absorb the dust, and will not completely block the voids in the fiber to hinder the flow of clean air.

　　 Warm reminder from China Compressor: It is recommended that users not only pay attention to the air filter itself, but also pay attention to the sealing problem of the pipe connection between the air filter and the intake valve.
