Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. In addition, the features of the embodiments and examples in the present application may be combined with each other without conflict.
The utility model relates to a typical implementation mode provides a reciprocating compressor piston and piston rod installation aligning tool, which comprises a baffle 1, a channel steel bracket 2, a supporting block 3, an adjusting bolt 4 and a locking nut 5; two baffles 1 are respectively installed at two ends of a channel steel support 2 through fixing screws 6, the lower portions of the baffles 1 protrude out of the bottom surface of the channel steel support 2, two vertical through holes are respectively formed in the middle of the channel steel support 2 and the middle of a supporting block 3, the supporting block 3 is arranged above the middle of the channel steel support 2, two adjusting bolts 4 respectively penetrate through the vertical through holes in the channel steel support 2 and the supporting block 3, and locking nuts 5 are installed on the adjusting bolts 4 at the top surface of the channel steel support 2.
The piston rod of the reciprocating compressor is connected with the crosshead by adopting a set of pressing device, and then a set of manual oil pressure pump is matched, the pressing device is a set of piston body and can be connected with an inner hole of the crosshead and the tail end of the piston rod, after the oil pressure pump is pressed, the tail end of the piston rod is stretched by the movement of the piston to generate elastic deformation, a locking nut on the compressor is screwed, the tail end of the piston rod is elastically restored after pressure relief, and the locking nut is naturally stressed to achieve a fastening effect; when the compressor is disassembled, the piston rod is pressed in the same way, the piston rod is elastically extended, the locking nut on the compressor is screwed out, the pressure is relieved again, and the piston rod and the crosshead can be separated. The whole installation process is complex and long in time, and the piston rod and the crosshead can be effectively connected through accurate alignment.
