Analysis of common faults of air compressor equipment

In the application of air compressor equipment, it may be disturbed by many factors, resulting in the failure of air compressor equipment and potential safety hazards. Therefore, it is necessary to interpret the common faults of air compressor equipment to lay the foundation for fault maintenance.

(1) Destructive failure

The so-called damaging fault is due to the fracture, ablation and deformation of the air compressor equipment, which affects the function of the equipment and even stops working.

(2) Degenerate fault

It is mainly affected by maintenance work and equipment wear factors, resulting in aging, deterioration and serious wear of relevant components of air compressor equipment, which is not conducive to the effective application of air compressor equipment.

(3) Loose fault

The components or bolts of the air compressor equipment are loose or even fall off, which affects the function of the equipment.

(4) Maladjusted type

The relevant control system of the equipment is out of order, resulting in high or low pressure of the equipment, endangering the safety of the compressor equipment.

(5) Blockage or leakage fault

Leakage or blockage of relevant passages of compressor equipment is not conducive to the normal operation of compressor.

Key technology of air compressor equipment fault maintenance

According to the basic fault situation of air compressor equipment, it is necessary to reasonably apply the key technology of fault maintenance, so as to achieve the purpose of fault treatment and realize the stable operation of air compressor equipment.

1. Fault diagnosis technology

After determining the cause of the fault, it is necessary to carry out the fault diagnosis reasonably. With the help of fault diagnosis, the specific fault parts and fault locations can be determined effectively. For the fault parts, the laboratory measurement method can be selected to complete the specific fault analysis. Taking infrared nondestructive testing technology as an example, with the help of infrared nondestructive testing technology, the defect diagnosis of compressor equipment can be completed.

(1) Principle. Infrared nondestructive testing technology is based on the principle of infrared radiation and uses infrared radiation to measure the internal energy flow of the target. Nondestructive testing can be realized by using infrared thermal imager to test the test results. In the specific detection, for the object without defects, the temperature field is evenly distributed after heat injection. For defective objects, thermal accumulation may occur.

(2) Used to diagnose fault types. Infrared nondestructive testing can be used to detect blockage or leakage faults, destructive faults and degraded faults, and effectively complete the diagnosis and control of compressor equipment.

2. Fault cause analysis technology

(1) Site investigation. With the help of field investigation, collect the information such as the occurrence time and environment of the fault, and complete the preliminary inspection and identification of the fault parts.

(2) Analyze the cause of the fault. With the help of laboratory inspection of fault parts, the comprehensive calculation and analysis of strength and fracture force of fault parts are completed. For the air compressor equipment that cannot be disassembled, the method of on-site data collection is mainly selected to complete the analysis and interpretation, and preliminarily determine the cause of failure.

(3) Fault conclusion. Combined with the measured effective data, the conclusion of fault causes is completed, and the appropriate fault maintenance method is selected.

3. Fault maintenance technology

After clarifying the specific fault location and causes, select effective maintenance methods to achieve troubleshooting.

(1) For destructive faults, the original components can be replaced to achieve the purpose of stable operation of the equipment.

(2) For degraded faults, analyze the state of components first. If they can be used again, they shall be applied again on the basis of maintenance. If there is serious degradation, it is necessary to replace the degraded parts of the equipment.

(3) In case of loose fault, the specific loose position shall be determined to complete the re reinforcement of structural members and bolts.

(4) The maladjusted fault needs to analyze the specific maladjusted components, complete the adjustment of relevant parameters, and then promote the stable operation of compressor equipment.

(5) Maladjusted fault repair. The relevant control system of the equipment is out of order, resulting in high or low pressure of the equipment, endangering the safety of the air compressor equipment.

(6) Repair of blockage or leakage. On the basis of clarifying the specific channel blockage and leakage area, dredge or replace the pipeline to achieve the effect of fault maintenance.

Key technologies of air compressor equipment maintenance

The maintenance of air compressor equipment is the basis to ensure the stable operation of compressor equipment and reduce potential safety hazards. Therefore, it is necessary to reasonably analyze the key technologies of compressor equipment maintenance according to the basic situation of compressor equipment.

1. Basic requirements for maintenance of air compressor equipment

(1) Safe. The air compressor equipment needs to have a good safety factor. With the help of maintenance work, the overall performance of the equipment is stable, especially the mechanical transmission system and dangerous parts of the compressor equipment, and the lines and pipelines are reasonably controlled. And ensure the stability of electrical system, operating system and safety protection system.

(2) Neat. The working environment and inside of the air compressor equipment shall be kept neat, and the relevant pipelines shall be kept neat, especially the exposed parts, which are vulnerable to the external environment. Therefore, it is necessary to ensure the cleaning of gearbox, oil hole and other parts of exposed parts to avoid adverse effects of impurities.

(3) Lubrication. Good lubrication can effectively avoid dry friction of air compressor equipment, so as to ensure the overall quality of compressor equipment.

2. Maintenance technology of air compressor equipment

According to the basic situation of air compressor equipment, it is necessary to regularly carry out the detection and inspection of compressor equipment, timely find the hidden dangers of compressor equipment, and complete the maintenance of compressor equipment.

(1) Regular patrol inspection. According to the application of air compressor, it is necessary to carry out the patrol inspection of compressor equipment regularly, so as to effectively complete the control of equipment. Formulate patrol inspection cycle and complete the maintenance of compressor equipment by means of daily inspection, weekly inspection and monthly inspection. During the actual patrol inspection, the operation status of the compressor equipment can be inspected through the senses to observe whether the compressor equipment is deformed, discolored, broken, etc. Check whether there is abnormal smell in transformers, lines, etc. through smell. Then listen to the sound and vibration rhythm with the help of the ear to judge whether there is any abnormality. With the help of hand touch, judge whether there is overheating.

(2) Adjustment and treatment technology. For the compressor, the maintenance work shall be carried out in strict accordance with the instructions to complete anti-corrosion, cleaning and power maintenance. And reasonably carry out the adjustment of relevant parts to ensure the stability and safety of each system of air compressor equipment.

(3) Equipment cleaning technology. The secondary equipment of the compressor equipment (the equipment that controls the main circuit of the compressor and plays a protective role is called the secondary equipment, such as relays, control switches, indicator lights, measuring instruments, etc.) is the basis for ensuring the stability and safety of the compressor. It is necessary to regularly carry out commissioning and management of the secondary equipment in combination with the basic situation of the compressor equipment, So as to ensure that the secondary equipment can effectively complete the monitoring of the compressor system.

(4) Build an intelligent online monitoring system. In order to ensure the stable operation of compressor equipment, the way of constructing intelligent online monitoring system is selected to complete the monitoring and management of compressor equipment, and the system automatically completes the monitoring and fault analysis of equipment, so as to effectively improve the operation state of equipment and avoid safety hidden dangers.
