Usually screw compressors need to be maintained after more than 2000 hours of operation. Air compressor oil is an essential part of the maintenance process, while air compressor oil has poor quality, many impurities and high viscosity. Easy to cause, air compressor oil shortage. The displacement of the bearing bush causes the internal oil circuit of the air compressor to be blocked, and the bearing bush and the connecting rod bush are strained or the matching clearance is too small. It is easy to cause the main shaft of the belt-driven air compressor to lock, and the bearing bush or connecting rod bush of the gear-driven air compressor to be abnormally loose.
The main components of air compressor oil are lubricating oil and base oil. The lubricating oil base oil is mainly divided into two categories: mineral base oil and synthetic base oil. The chemical composition of mineral base oil for air compressor oil includes high boiling point, high molecular weight hydrocarbons and non-hydrocarbon mixtures.
The main production processes of lubricant base oil for air compressor oil are: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrogenation supplementary refining. According to the quality and performance requirements of the screw air compressor lubricating oil, careful selection of additives, careful balance, and reasonable deployment are the key to ensure the quality of lubricating oil.
When the oil-free air compressor is designed and manufactured, no lubricating oil is used in the compression chamber, so theoretically, the oil will not directly contact the compressed air during the compression process. However, this does not mean that the compressed air produced by the oil-free air compressor is completely oil-free. In fact, due
As one of the general equipment, screw air compressor is widely used in electronics, chemical industry, food processing, textile and other fields. So what are the main uses of the screw air compressor in these areas? The main uses of the screw air compressor are:
Whether the mobile air compressor is a special equipment depends on its specific parameters and uses. Generally speaking, the air compressor is a general-purpose mechanical equipment, and only when its gas tank (pressure vessel) meets the conditions of special equipment, it needs to be managed according to the special equipment.
The efficiency of the screw air compressor is usually relatively high, but the specific efficiency will be affected by many factors. The following is a detailed analysis of the efficiency of the screw air compressor: Efficiency range: The efficiency of the screw air compressor is generally between 75% and 90%. This is a phase
Oil-free and oil-free air compressors have their own advantages and applicable scenarios, and it is impossible to simply say which is better. Which type of air compressor to choose depends on the specific application requirements and working environment. The advantage of oil-free air compressors is that they provide compressed air
The provisions on the design service life of pressure vessels mainly come from national standards, industry norms and the agreement between the design client and the design unit. Specifically, it can be summarized into the following aspects: 1. national standards and industry norms "fixed
As an important industrial equipment, air compressor will experience various changes in load and working environment during long-term operation, which will affect the performance and life of air compressor. Therefore, regular maintenance is to ensure that the air compressor sustained, stable, high
The pressure of the plant's gas source is lower at night than during the day, which may be caused by various reasons such as environmental temperature change, equipment operation status, pipeline system problems, user demand change or external factors interference. The following is a specific analysis: 1. the influence of environmental temperature change The temperature difference between day and night
The first maintenance time of the new air compressor may vary according to different situations and manufacturer recommendations. However, in general, the new air compressor should be maintained for the first time after 500 hours of operation. This maintenance is relatively simple, mainly to replace the oil, oil filter and air
Screw compressor applicable industry analysis Screw air compressor as the core equipment of industrial air source system, its application scenarios cover a wide range of compressed air quality, pressure stability and environmental protection requirements.
