Air compressor maintenance and repair strategy
1. Analysis of common problems of air compressor
Common air compressor failures are mainly divided into several types, including insufficient air volume of the air compressor, abnormal pressure, abnormal operation of the power on, high temperature of the machine, and even explosive combustion. During daily operation and use, impurities, dust, etc. in the air enter the air compressor, or the parts of the air compressor wear out, which may lead to failure problems. According to the specific problem, the cause of the fault is analyzed, and the strategy for solving the fault can be found in a targeted manner to maintain the normal and stable operation of the air compressor.
First of all, the pressure of the air compressor is not normal and the shortage of exhaust gas is caused by the wear of the parts. The parts wear out during the long-term collision process, and the gap between the parts increases, resulting in changes in the displacement and pressure. .
Secondly, the difficulty of starting the air compressor is generally due to the fact that the monitoring device cannot operate normally. After the monitoring device is abnormal, the air compressor cannot be operated, which makes the air compressor difficult to start.
Finally, the abnormal hot and cold on the surface of the air compressor, explosion, etc. are caused by the failure of the cooling system. The cooling system can not work normally, and the normal temperature of the surface of the air compressor can not be maintained, which causes the air compressor to overheat or even explode [1].
In order to truly solve the problem of air compressor failure, it should be studied and discussed from the fundamental aspects of air compressor design and production. In the design of the air compressor, according to the needs of industrial production and construction industry, the functional requirements of the air compressor are also different. If there is a flaw in the design process, or where the actual demand does not match, it will lead to daily life. The air compressor during operation has failed.
In addition, the function of the air compressor in the daily operation process needs to be properly managed. In many common faults of air compressors, explosion and combustion pose the greatest threat to the safety of workers' lives and property. Under normal circumstances, after the damage of the cooling system, the temperature of the air compressor can not be controlled within a reasonable range. The temperature rises and eventually an accident occurs. Regardless of the occurrence of any kind of failure, the reasons are mostly unscientific design, improper management, and inadequate maintenance and repair work. Therefore, in order to avoid the failure of the air compressor, maintenance and repair management needs to be carried out from several angles [2].
In general, the occurrence of air compressor failures is related to irregular use and imperfect maintenance systems. The use of the specification can greatly extend the life of the air compressor and reduce the frequency of failure of the air compressor. A sound overhaul system can detect problems in the operation of the air compressor early, and take corresponding measures in time to kill the problem in the cradle, avoiding the deterioration of subsequent problems.
2. Discussion on maintenance and maintenance strategy of air compressor
Air compressor equipment problems are often concentrated in the oil circulation system, gas circulation system, water circulation system, and other systems. Therefore, this section briefly analyzes these systems and proposes corresponding maintenance measures.
(1) Maintenance of the oil circulation system
Before the air compressor is put into use, it is necessary to test each system to ensure the normal operation of the air compressor. The air compressor oil circulation system provides the lubricating oil required for operation of each component of the air compressor. Therefore, the normal operation of the air compressor oil system can greatly reduce the wear between the devices, thereby increasing the service life of the air compressor. In the maintenance and repair process of the air compressor, the first is the daily inspection and maintenance of the oil circulation system. The purpose of this work is to ensure that the various components in the air compressor have good lubricity and avoid excessive production. Wear and loss. The maintenance personnel should check the lubrication degree of various parts inside the air compressor. If the lubrication is insufficient, the lubricating oil should be added in time to ensure the balance between the temperature and the oil pressure in the air compressor to avoid excessive wear and tear of the parts due to insufficient lubrication. Question [3].
(2) Maintenance of the pneumatic circuit system
The gas circulation system mainly refers to a system that sucks and compresses air. In this system, the compressed air needs to be cooled and cooled to avoid unstable operation of the air compressor caused by excessive temperature. Therefore, this system is also the core system of the air compressor. Whether the gas circulation system can work stably depends directly on whether the air compressor can normally compress the air. Therefore, the maintenance of the pneumatic circuit is very important. When inspecting the pneumatic circulation system, ensure that the various components in the circulation system are normal, and focus on checking whether the gas will recirculate in the circulation system. Once this problem occurs, the suspension full check valve needs to be installed.
(3) Water circulation system maintenance
A large amount of heat is generated during the operation of the equipment. Heat causes the temperature of the compressed gas and the device to rise due to radiation, conduction, and the like. Therefore, the normal operation of the water circulation system can effectively reduce the temperature of the compressed gas and each device, and ensure that the compressor operates at a suitable temperature. The water circulation system mainly plays the role of cooling compressed gas. For the maintenance work of this system, it is necessary to focus on the cooling time problem to ensure that the water circulation system can operate normally in the air compressor and play a role. The maintenance of the water circulation system is an important part of the maintenance work of the air compressor. It is necessary to ensure the normal and stable water circulation system, so as to avoid problems such as explosion, short circuit or power failure due to excessive temperature of the air compressor. The normal operation of the press [4].
(4) Maintenance measures for common faults
1) The air compressor has insufficient exhaust. The amount of exhaust gas greatly affects the operating efficiency of the air compressor. Therefore, if the air compressor has a problem of insufficient exhaust gas, firstly, it is possible to replace the damaged or cracked parts, then check and clean the air muffler, and finally replenish the oil in the cylinder to keep the oil level in the cylinder oil level. More than a third.
2) The air compressor cooling system is faulty. If there is a problem with the air compressor's cooling system, it is mostly due to fouling in the cooling system or air entering the cooling system. In response to this problem, air can be prevented from entering by installing a casing on the water meter, or the cooler core can be frequently replaced to avoid fouling and ensure the normal operation of the cooling system.
3) Air compressor air tightness problem. If the air compressor has a problem that the air valve compactness is lowered, the operation of cleaning the valve plate and the valve plate is performed. Finally, we must actively implement the operation of removing carbon deposits, or choose to control the electrostatic plastic pipes produced by carbon deposition, effectively improve the cleanliness of the air compressor and avoid the occurrence of faults.
4) The air compressor oil should be replaced in time. The quality of the lubricating oil affects the operation effect of the air compressor. Therefore, after the air compressor is put into operation, the lubricating oil can be replaced every 6000-7000 hours, which can effectively improve the quality of the lubricating oil. On the whole, maintaining the cleanliness and integrity of the various components of the air compressor is an effective maintenance measure to ensure the normal operation of the air compressor. In addition, it is sufficient to ensure the internal oil volume of the air compressor, improve the maintenance and inspection work of the air compressor, and comprehensively ensure that the air compressor plays a good role [5].
(5) The use and maintenance of air compressors are inseparable from a scientific and sound management system. The standardized use method can effectively avoid unnecessary failure of the air compressor, and the scientific and perfect management system can find the problems of the air compressor itself in the first time, and at the same time enable the management and maintenance personnel to take effective methods in time. Thereby preventing the deterioration of the problem. Specifically, after the installation of the air compressor, the air compressor production unit needs to provide training for the use of the equipment for a period of time, thereby improving the skill level of the operator using the air compressor. And let the equipment operators and equipment maintenance personnel of the use unit have a clear understanding of the various components of the air compressor. Thereby ensuring good operation of the air compressor during subsequent use and maintenance.
3. Conclusion
In summary, with the acceleration of China's economic development speed, air compressors have been more and more widely used in various industrial production and construction industry construction processes. Due to the deposition of impurities in the air and insufficient lubrication effects, Air compressors often have various faults, which cause the function of the air compressor not to be effectively played. In order to avoid this situation, the routine maintenance and fault repair strategies of the air compressor, including wear or damage of components, Insufficient exhaust volume, poor quality of lubricating oil, carbon deposit problems, etc., only by doing daily inspection and maintenance of air compressors, can effectively avoid various problems, ensure the normal operation of air compressors, reduce property losses, and improve Economic benefits of industrial production and construction.
