The leakage of Hydrogen Compressor may be caused by various reasons, and the following are some main reasons for analysis:
Aging of seals: After prolonged use, the seals of hydrogen compressors may lose their sealing performance due to aging, resulting in end leakage. This is a common cause of compressor leakage.
Locking bolt defect: If the locking bolt of the hydrogen compressor is loose or defective, it may cause cracks and gaps in the connection part, resulting in air leakage. Therefore, regular inspection and tightening of locking bolts are important measures to prevent air leakage.
Design defects: If there are defects in the design of the hydrogen compressor, such as improper connection design, unreasonable sealing design, etc., it can also lead to gas leakage. In this case, it may be necessary to redesign or improve the structure of the compressor.
Improper operation: If overload is not properly prohibited during operation, or if the load is not synchronized during work, improper operation may also cause compressor leakage. Therefore, proper operation of the compressor is an important prerequisite for avoiding air leakage.
Packing sealing issue:
Wear of packing seal ring: Abnormal wear of the packing box seal ring in reciprocating compressors may lead to air leakage. This may be caused by installation issues, surface wear of the piston rod, improper adjustment of the axial clearance of the sealing ring, damage to the pre tension spring, and other reasons.
Unreasonable structure of packing box: Unreasonable structure of packing box, such as difficulty in installation due to excessive depth of the cylinder, or improper position of the cooling water chamber, which cannot effectively remove heat and may also cause air leakage problems.
Poor cooling effect: If the cooling system of the compressor is not effective, it may cause the packing components to come into contact with the piston rod and generate high temperatures during actual operation, thereby accelerating the wear and leakage of the packing components.
Piston rod jumping: Excessive piston rod jumping may cause the cylinder head of the unit to vibrate, resulting in a smaller gap between the piston rod and the packing box, and even wear during contact, leading to air seal leakage.
For the above reasons, the following measures can be taken to prevent hydrogen compressor leakage:
Regularly inspect and replace aging seals.
Ensure that the locking bolts are tightened and in good condition.
Fully consider the sealing performance and structural rationality of the compressor during the design phase.
Operate the compressor correctly to avoid issues such as overload and asynchronous load.
Regularly inspect and maintain the packing sealing ring and packing box to ensure they are in good condition.
Improve the cooling system to enhance the cooling effect.
Control the jumping value of the piston rod to ensure that it is within the specified range.
In summary, the causes of hydrogen compressor leakage may involve multiple aspects, and it is necessary to comprehensively consider and take corresponding measures to prevent and solve them.
