According to the structure of the compressor, air compressor oil is divided into two types: reciprocating air compressor oil and rotary air compressor oil, each has three levels of light, medium and heavy load. Air compressor oil can be divided into mineral oil compressor oil and synthetic compressor oil according to the type of base oil. Air compressor oil is mainly used for the lubrication of th...

Many factories believe that the maintenance of screw air compressors is maintenance of 3 filters and 1 engine oil in 2000hrs. But this is only basic maintenance. In-depth maintenance is divided into 5 stages. If you can do a good job of deep maintenance. Then your air compressor can have a longer service life. Maintenance time and content of the air compressor.   1. Maintenance time and ...

Due to the lack of understanding of air compressors by some business managers, the continuous operation of the air compressor is based on the principle of keeping the equipment in good condition and not repaired, resulting in long equipment running time but lack of maintenance, and failures may occur at any time. 1. The subjective cause of the accident The management of the equipment supervisor is...

Recently, I have encountered the same problem as a customer inquiries: the safety valve of the air compressor frequently jumps and the oil is sprayed. I don't know where the problem is? Through many years of service experience, it is concluded that the main factors of the safety valve take-off failure of the screw air compressor are the following four aspects: 1. The large oil partial pressure dif...

The maintenance content of the pressure vessel in the air compressor system during the outage period is as follows: 1.Keep the pressure vessel dry and clean to prevent atmospheric corrosion. Scientific practice has proved that dry air generally does not corrode carbon steel and other ferroalloys. Corrosion starts only when there are dust, dirt or old corrosion products on the metal surface when we...

The main manifestations of air compressor not pumping up and insufficient air pressure are as follows: the air compressor does not discharge air under pressure and when the main engine is running and the air compressor is inflating the air tank, the barometer indicates the starting pressure value of the air pressure. A: General reasons and solutions for the air compressor not pumping up when loade...

There are many reasons for the abnormal shutdown of the air compressor. Excessive temperature is an important reason. Excessive temperature will cause some parts of the air compressor to fail to operate normally, resulting in shutdown. Reason analysis of high temperature of screw air compressor: ① Insufficient amount of lubricating oil, incorrect specifications of lubricating oil, different viscos...

(Variable Speed Drive) VSD Air Compressor Variable Speed Driver , usually abbreviated as VSD, is a symbol of the compressed air field. The air compressor equipped with VSD can automatically adjust its operating speed to accurately match the compressed air demand in real time. Considering that the biggest aspect of the total cost of ownership of an air compressor is the power it consumes, not the p...

Compared with conventional screw air compressors, variable frequency screw air compressors use adjustable air volume and smooth start-up. The air supply pressure is more stable than conventional screw air compressors , but sometimes variable frequency screw air compressors like power frequency compressors appear: Frequent loading and unloading situations. According to the analysis of this phenomen...
