The change of the longitudinal structural size of the horizontal compressor will directly affect the cylinder running clearance, which will have a certain impact on the operation of the marine horizontal compressor. Therefore, in order to make the designed and installed marine horizontal compressor have reasonable cylinder running clearance, after the deformation of the hull in the hull is measured and bent into the hull, the running clearance of the horizontal compressor of the marine unit and the general The relationship between the cylinder running clearance of the horizontal compressor can be determined by the following formula: The new calculation formula for determining the minimum clearance of the cylinder installation clearance of the marine horizontal compressor is represented by R, which represents the minimum installation clearance of the horizontal compressor cylinder of the marine, denoted by R All parameters and dimensions except the installation clearance and running clearance of the cylinder are the same as those of the horizontal compressor of the marine horizontal compressor. In order to ensure that the horizontal compressor arranged along the longitudinal direction of the hull can operate normally while the ship is sailing, it should be based on the “traditional methodâ€.
The influence of the overall bending deformation of the hull is organically dissolved into the calculation of the installation clearance and running clearance of the marine horizontal compressor cylinder, and a new calculation formula for the minimum clearance of the cylinder installation clearance of the marine horizontal compressor is proposed.
The author believes that the cylinder clearance of marine horizontal compressors can be determined according to the formula recommended in this paper, which makes the cylinder clearance of marine horizontal compressors more suitable for the actual situation. It is expected that the cylinder assembly clearance according to the new formula of this paper has positive significance for improving the safety of horizontal compressors for ships, which can significantly reduce the failure rate of horizontal compressors, ensure the horizontal compressor can operate normally and safely, and thus Safe navigation of ships provides more adequate protection.
