Abstract
The utility model relates to a compressor crosshead connected with a piston rod, in particular to a flange-type crosshead with an adjusting disc. The utility model is realized as follows: the compressor flange-type crosshead with the adjusting disc consists of the piston rod, a crosshead flange and a crosshead body, and is characterized in that the piston rod 1 is fixed on the crosshead flange through a fastening nut, the crosshead flange is assembled on the crosshead body through a bolt and a nut, and the adjusting disc is tightly combined on the side plane of the crosshead flange. The compressor crosshead has the advantages of shortening the time of jumpiness value of the piston rod of the compressor, reducing labor intensity and risk, and improving safety.
Description
Technical field
The utility model relates to the crosshead that a kind of compressor connects piston rod, especially relates to a kind of flange-type crosshead of compressor band adjustment dish.
Background technique
The crosshead of crank-linkage type piston compressor is that rotatablely moving of bent axle 13 is converted to piston 11 reciprocating transition member.The utility model is the improvement to the crank-linkage type piston compressor, hereinafter to be referred as compressor.In compressor, beating of piston rod 1 is related to the workmanship of compressor.In the running of compressor, crank 13 is made even angle rate and is rotated, and piston 11 and crosshead are reciprocating, and piston rod 1 connects between piston 11 and the crosshead also reciprocating, referring to Fig. 1.Because the amount of deflection that piston rod 1 itself produces, and the different running clearance of crosshead and piston 11, make piston rod 1 present dancing or claim jumping phenomena in level and Vertical direction.Be harmful to though produce this phenomenon, but inevitably.Our purpose is to control jitter values in allowed limits, otherwise can shorten the life-span of stuffing box, piston ring, supporting ring greatly.Jitter values adjusted before dispatching from the factory arrives the scope that allows, but compressor operating is after the regular hour, fulcrum place at piston rod 1 two ends, be the first side of cross and piston 11 1 sides of piston rod 1, the normal wear of non-equivalence can appear, cause the jitter values of piston rod 1 to exceed allowed band, so must adjust.Adjusting method commonly used at present is to take out crosshead, adjusts crosshead crawler shoe 9 and adjusts pad 10, because crosshead is heavier, need the several people to finish jointly, add to guarantee once can adjust to the right place, take time and effort, labor intensity is big, and very big danger is arranged.
The model utility content
The purpose of this utility model provides a kind of flange-type crosshead of compressor band adjustment dish, can conveniently adjust the jitter values of piston rod.
The utility model is achieved in that a kind of flange-type crosshead of compressor band adjustment dish, is made of piston rod 1, crosshead flange 2 and crosshead body 3; It is characterized in that: described piston rod 1 is fixed on the crosshead flange 2 by fastening nut 5, and crosshead flange 2 fixedly is assemblied on the cross body 3 by bolt 6, nut 7, close-fitting one adjustment dish 4 on the side plane of described crosshead flange 2.
Four of five equilibriums are adjusted 8, four adjustment of screw screw 8 and are positioned outer ring, crosshead body 3 joint on the outer ring of described adjustment dish 4.
The utility model has the advantages that, shorten time, the reduction labor intensity of adjusting compressor piston rod 1 jitter values, reduce danger, improved Security.
Fig. 1: flange-type crosshead construction of the present utility model longitudinal section schematic representation
Fig. 2: be the structure longitudinal section schematic representation of traditional crosshead assembly.
Specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Flange-type crosshead with reference to a kind of compressor band of Fig. 1 adjustment dish is made of piston rod 1, crosshead flange 2, crosshead body 3, adjustment dish 4; Described piston rod 1 is fixed on the crosshead flange 2 by fastening nut 5, crosshead flange 2 fixedly is assemblied on the crosshead body 3 by bolt 6, nut 7, close-fitting one adjustment dish 4 on the side plane of described crosshead flange 2, coiling four of five equilibriums on 4 outer rings in adjustment adjusts 8, four on screw and adjusts the outer ring that screw 8 is positioned crosshead body 3 joints.
When adjusting the jitter values of crosshead body 3 as need, need not to propose crosshead body 3, as long as unclamp the nut 7 that connects crosshead flange 2 and crosshead body 3, on the adjustment dish 4 four adjust screw 8 as required, can be adjusted to piston rod 1 jitter values within the scope of requirement, by nut 7 crosshead flange 2 be fixedlyed connected with crosshead body 3 then, just finish adjustment process, promptly convenient, quick, safety.
