The reciprocating compressor is a general machine, belonging to a positive displacement compressor. The reciprocating compressor is a compressor which periodically changes the volume of a cylinder body by the reciprocating motion of a piston or a diaphragm in a cylinder and performs pressurization and delivery of gas, and is classified into a piston type compressor and a diaphragm type compressor according to a reciprocating member.
When the reciprocating compressor works, the crankshaft drives the connecting rod, the connecting rod drives the piston, and the piston moves up and down. When the piston moves downwards, the volume of the cylinder is increased, the air inlet valve is opened, the air outlet valve is closed, air is sucked in, and the air inlet process is completed; when the piston moves upwards, the volume of the cylinder is reduced, the air outlet valve is opened, the air inlet valve is closed, and the compression process is completed. Usually, the piston has a piston ring to seal a gap between the cylinder and the piston, and the cylinder has a lubricating oil to lubricate the piston ring.
The crosshead-slideway clearance is large and the crosshead pin and connecting rod bolt looseness is more prominent among failure causes of the reciprocating compressor. These faults are often associated with piston rod bounce anomalies, which require reverse maintenance in the process. Piston rod bounce is used to determine the horizontal and vertical position associated with the cylinder and crosshead pair, i.e., a measure of the change in the piston rod running-in pair. Meanwhile, the piston rod runout is also an important index for the service life of each part of the compressor.
In the prior art, in order to ensure that the piston rod runout is within a specified value range, the problems are generally solved by adjusting the centering of a compressor and the height of a crosshead, namely, a crosshead shoe gasket is adjusted to meet the condition that the radial runout value exceeds the standard, but large units and integral crosshead are difficult to extract the shoe gasket, so that the adjustment cannot be carried out through the crosshead shoe gasket.

The purpose of the utility model is realized by the following technical measures: an integral crosshead flange adjustable adjusting plate assembly of a large reciprocating compressor comprises an adjusting plate; the adjusting plate is disc-shaped, the middle part of the adjusting plate is provided with a shaft hole, at least two connecting holes are uniformly formed between the shaft hole and the outer edge of the adjusting plate, the outer edge of the adjusting plate protrudes towards a flanging at one side to form a circular table edge, and a threaded hole is radially formed in the circular table edge.
Particularly, the outer diameter of the shaft hole is slightly larger than the outer diameter of the inner end of the crosshead body, and the inner diameter of the shaft hole is the same as the inner diameter of the crosshead body.
In particular, the location and number of the connection holes is the same as the flange.
In particular, four threaded holes are formed, and a right-angle included angle is formed between the four threaded holes.
In particular, a leveling pad is attached to the rear side of the leveling plate.
In particular, the threaded hole is provided with a jackscrew.
The utility model discloses an advantage and effect: through increase the adjusting plate in the middle of crosshead body and flange, the installation is maintained swiftly, adjusts convenient safe high-efficient, shortens the time of readjusting the crosshead height to and shorten the time of whole centering adjustment, also conveniently change the compressor vulnerable part, reduce operating strength and the simple too much consumption of labour that economizes, show to improve current crosshead and piston rod centering adjustment technique.
