Control of gap between front and rear dead centers of reciprocating compressor
Thread Content
How much clearance should be controlled between the front and rear dead centers of the reciprocating compressor piston?
It should be adjusted according to the technical documentation of the compressor, but generally it should be 3-5mm. Generally, the cylinder head side is required to be larger than the crankshaft side during adjustment.
There is also a big difference in the adjustment of the dead center clearance between horizontal and vertical reciprocating compressors. Generally, the inner dead center clearance of the vertical type is larger than that of the horizontal type.
The values vary depending on the model and manufacturer's design.
2-5mm is normal, it depends on the situation and is related to the clearance.
It also has something to do with the impurity content in the gas. If it contains more water, the gap should be slightly larger.
The top dead center of a section is 4MM, the bottom dead center is 3MM, and the others are all 3MM.
Determine the inner and outer dead center clearances based on the total clearance during compressor design: 1: The clearance ratio between the inner and outer dead centers of a horizontal reciprocating compressor is 4: 6. 2. The clearance ratio between the inner and outer dead centers of the vertical reciprocating compressor is 1: 1
It is inappropriate to use specific numbers. The clearance of each compressor will be different, and the machine manual will have relevant data. If there is no corresponding data, just ensure one principle, that is, the cylinder head side clearance should be equal to or slightly larger than (generally 0.5~1mm) the crankshaft side clearance.
Just control the required clearance according to the technical document requirements
This is based on the total clearance of your compressor. According to the total clearance at top dead center and bottom dead center, generally the clearance at the head of the post is larger. You can determine it yourself based on the actual situation.
Each one is different. . Look at the drawings and instructions given by the manufacturer. . There must be detailed requirements
