The function of the components of the oil-injection screw air compressor is introduced, and the working principle of the components is analyzed. Precautions during maintenance and analysis and troubleshooting of individual faults. 1. Lubricating oil Lubricating oil has the functions of lubrication, cooling, and sealing. 1) Pay attention to the oil level of the lubricating oil. Lack of oil can...

The oil is always in the best condition: Correct selection of lubricating oil - it is necessary to consider these characteristics of lubricating oil: proper viscosity characteristics, good oxidation resistance stability, good demulsibility and foam resistance, and low residual carbon value. Prevent oil shortage - although the lubricating oil system is a closed circuit for the air compressor, there...

When the air inlet filter element is blocked more and more seriously, the suction resistance will become larger and larger, and the amount of air entering the gas air compressor will be reduced, which will lead to insufficient exhaust volume and reduced operating efficiency of the air compressor. If the differential pressure gauge cannot be used for measurement, the filter can be replaced every 10...

For any small and medium-sized enterprise, a set of air compression system is a costly investment, so maintaining its efficient operation is the primary task of all end users. In theory, the initial investment of equipment accounts for 15%, the maintenance and management costs during the use period account for 15%, and 70% of the costs come from energy consumption. Therefore, in order to reduce th...

Removal of insufficient pressure 1. Plugging The way to reduce gas consumption is to check the operation of the drive air compressor and its pipe network, focusing on whether there is leakage. Small leakage is not easy to find, and large leakage will naturally cause system pressure drop and gas consumption reduction. According to statistics, the average leakage of compressed air accounts for 30% o...

Reasons for insufficient pressure 1. The gas consumption is greater than the gas supply The discharge pressure of the compressor can not reach the rated pressure. One common reason is that the user's gas consumption suddenly increases. One compressor is not enough, and it is too wasteful to open another compressor. 2. The air filter is blocked Among the alarm faults of screw compressor, the most f...

Screw air compressor is widely used, and regular maintenance is the premise to ensure its normal operation. The main engine is the core part of the air compressor, which has been operating at a high speed for a long time. Similar to most operating machines, it must undergo preventive overhaul after a certain period of time or service life. The overhaul period is usually 30000-40000h (4-5 years). 0...

During the operation of the compressor, many supporting accessories need to be well matched to meet the gas demand of the terminal, and the pressure vessel (gas tank) is one of the indispensable accessories. It can stabilize the pressure of the pipe network system, remove some pollutants, reduce the frequent startup and shutdown of the compressor, extend the service life of the compressor, and red...

No matter what brand of oil injection air compressor, its compression working principle is the same, and the functions of each valve are roughly the same. If we can thoroughly understand the design function and working principle of each valve, we will give some support and help to solve the common faults of the air compressor! The five major valves of the oil injection air compressor are: unloadin...

First of all, we need to understand why the screw air compressor accumulates water: 1. When the screw air compressor is running, the compressed air contains condensed water in the atmosphere. During the continuous operation of the machine, after the oil temperature gradually rises to 80°C, the condensed water in the oil begins to volatilize, and the water is discharged with the compressed air. in ...
