Abnormal shaking of Hydrogen Compressors may be caused by various reasons, and the following is an analysis of some of the main reasons:
Small clearance between piston stop points:
When the clearance between the piston dead center of the hydrogen compressor is too small, the friction between the piston and the cylinder wall will increase, causing abnormal vibration of the compressor.
Solution: Check and adjust the piston stop clearance to ensure it is within a reasonable range.
Loose connecting nut of piston rod:
If the connecting nut of the piston rod is loose, it will cause the piston rod to shake during movement, thereby causing the compressor to shake.
Solution: Tighten the piston rod connecting nut to ensure a secure connection.
The air valve is not working properly:
If the air valve does not work properly, such as damaged valve plates, spring failure, etc., it will cause poor gas flow, pressure fluctuations, and thus cause compressor vibration.
Solution: Check and clean the air valve, replace damaged valve plates or springs.
Piping issues:
Unreasonable piping design or improper installation, such as excessively long, thin, or bent pipes, can cause vibration and noise during gas flow, leading to compressor vibration.
Solution: Optimize piping design and eliminate vibration sources.
Abnormal rolling bearings:
If the quality of the compressor bearing parts does not meet the standards, tilting, bending and other phenomena may occur during operation, causing the axis line and the inner ring of the bearing to not overlap well, resulting in compressor vibration.
Solution: Check the quality of the bearing parts and replace the unqualified bearings.
Unbalanced rotor:
Defects in rotor component design, rotor eccentricity, rotor scaling or wear can all lead to rotor imbalance, which in turn can cause compressor vibration.
Solution: Check and repair the rotor components to ensure rotor balance.
Coupling misalignment:
If the coupling is not aligned, it can cause the axis of the compressor rotor to deviate from the axis of the motor bearing, leading to compressor vibration.
Solution: Adjust the alignment of the coupling to ensure good alignment.
Loose, deformed, or cracked supports, shells, and foundations:
If these supporting components have problems, it will lead to a decrease in the overall stability of the compressor, which in turn can cause vibration.
Solution: Check and reinforce components such as supports, shells, foundations, etc. to ensure their stability and reliability.
In summary, the causes of abnormal vibration in hydrogen compressors may involve multiple aspects and require comprehensive consideration of various factors for investigation and repair. In practical operation, corresponding solutions should be taken according to the specific situation to ensure the normal operation and safety of the compressor.
To avoid abnormal shaking of the hydrogen compressor, prevention and maintenance can be carried out from the following aspects:
1. Equipment design and selection
Reasonable selection of compressor type:
Select the appropriate type of hydrogen compressor based on actual needs and process conditions, such as reciprocating, centrifugal, etc.
Ensure that the working pressure, flow rate, speed and other parameters of the compressor match the process requirements.
Optimize piping design:
Reasonably design pipeline layout to avoid problems such as excessively long, thin, and bent pipelines.
Ensure that the pipeline connection is secure and eliminate vibration sources.
Select high-quality components:
Choose reliable components such as pistons, cylinders, bearings, couplings, etc.
Ensure that the accuracy and fit clearance of the components meet the design requirements.
2. Installation, debugging, and maintenance
Accurate installation and debugging:
During the installation process, ensure that the connection between the compressor and the foundation, pipelines, and other components is firm and reliable.
Debug according to requirements to ensure smooth operation of the compressor.
Regular inspection and maintenance:
Regularly inspect and maintain the compressor, including cleaning, lubrication, fastening, etc.
Check the tightness of key components such as piston stop clearance and piston rod connecting nuts.
Check the working status of the air valve and replace damaged valve plates and springs in a timely manner.
Keep the equipment clean and dry:
Regularly clean the compressor to ensure that the equipment surface is free from dust and corrosion.
Keep the operating environment of the equipment dry to prevent moisture from entering the interior of the equipment.
3. Operation monitoring and troubleshooting
Real time monitoring of vibration:
Install vibration sensors on the compressor to monitor vibration in real-time.
Once abnormal vibration is detected, immediately stop the machine for inspection and troubleshooting.
Pay attention to the operating parameters:
Pay close attention to the operating parameters of the compressor, such as pressure, flow rate, temperature, etc.
Adjust and handle abnormal parameters in a timely manner.
Troubleshooting and repair:
When the compressor experiences abnormal shaking, follow the troubleshooting process for troubleshooting.
Based on the investigation results, corresponding repair measures will be taken, such as replacing damaged components, adjusting equipment parameters, etc.
4. Training and Personnel Management
Strengthen personnel training:
Provide training to operators on compressor operation and maintenance.
Improve the skill level and safety awareness of operators.
Establish management system:
Develop a management system for compressor operation and maintenance.
Clearly define the responsibilities and operational standards of the operators.
Regular assessment and evaluation:
Regularly assess and evaluate operators.
Based on the assessment results, corresponding rewards and punishments will be given.
In summary, avoiding abnormal shaking of hydrogen compressors requires comprehensive consideration and implementation from multiple aspects such as equipment design and selection, installation, commissioning and maintenance, operation monitoring and troubleshooting, as well as training and personnel management. By implementing these measures, the stable operation and safety of the compressor can be ensured.
