Description
Technical field
The utility model belongs to the compressor apparatus technical field, relates in particular to a kind of piston rod of reciprocating compressor.
Background technique
In the process of operation of reciprocating compressor, the position that compressed gas can pass the cylinder seat by piston rod is to external leakage, and filler is exactly the device that stops this leakage.Must be close to piston rod during packing sealing ring work, when piston rod moved reciprocatingly, packing sealing ring produced heat with the phase mutual friction meeting of piston rod surface.Because the high pressure filling seal ring all is to adopt the filled polytetrafluoroethylene material, the heat-conducting property extreme difference is difficult to from seal ring the fricative heat of piston rod be conducted.Under high temperature, high pressure and high-revolving operating mode, more easily cause a series of faults such as excessive heating, wearing and tearing aggravation, gas leakage.For solving this phenomenon, the now cooling of filler and piston rod mainly contains two kinds of methods: the one, by in stuffing box, injecting cold oil, oilcloth to piston rod surface, then along with cold oil is struck off in the motion of piston rod; The second is directly to get out a passage in filler, and cooling liquid is directly delivered in each box of filler and circulated, and discharges at last.The major defect of the first cooling means is: the flow of cooling liquid is too little, has no idea to be cooled to fully required temperature for high temperature, high pressure and high-revolving operating mode.The second cooling means structure is comparatively complicated, and cooling liquid is easily revealed, installation and maintenance complicated.
The model utility content
The utility model provides a kind of piston rod of reciprocating compressor with radiating structure for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: piston rod of reciprocating compressor comprises the piston rod body, is provided with the piston joint at the one end, and the other end is provided with the crosshead joint; Be provided with the oil duct that is extended inward into mid-rear portion by the end face of described crosshead joint at the center of described piston rod body, the outer end of described oil duct is provided with the joint with internal thread; In described oil duct, also be provided with oil pipe, be provided with oil deflector between the inner of described oil pipe and the described oil duct, also be provided with oil outlet on the outer wall of described oil pipe the inner, the outer end of described oil pipe is provided with externally threaded oil-feed silk head, and this oil-feed silk head is connected to the joint on the described oil duct; On the outer wall of the piston rod body of described crosshead joint inboard, also be provided with the oil drain out that is communicated to described oil duct.
Advantage of the present utility model and good effect are: compressor piston rod of the present utility model arranges oil pipe and oil duct by the inside at the piston rod body, formation through oil-feed silk head to oil pipe to oil outlet to oil duct again to the cold oil peripheral passage of oil drain out, the cooling heat dissipation effect is excellent.
Preferably: on the outer wall of described crosshead joint, also be provided with the groove of annular, be provided with seal ring in this groove.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 to Fig. 3, the utility model comprises piston rod body 1, is provided with the piston joint at the one end, and the other end is provided with the crosshead joint, forms the path of cold oil in the inside of piston rod body 1.
Be provided with the oil duct that is extended inward into mid-rear portion by the end face of crosshead joint at the center of piston rod body 1, the outer end of this oil duct is provided with the joint with internal thread.
In oil duct, also be provided with oil pipe 2, be provided with oil deflector 3 between the inner of this oil pipe 2 and the oil duct.Also be provided with oil outlet on the outer wall of oil pipe 2 the inners, the outer end of oil pipe 2 is provided with externally threaded oil-feed silk 4, this oil-feed silk 4 joint that are connected on the oil duct.On the outer wall of the piston rod body 1 of crosshead joint inboard, also be provided with the oil drain out that is communicated to oil duct.Like this, just formed in the inside of piston rod body 1 one through oil-feed silk 4 to oil pipe 2 to oil outlet to oil duct again to the cold oil peripheral passage of oil drain out, cold oil enters, discharges through oil drain out from oil-feed silk 4, takes away the heat that piston movement produces.
On the outer wall of crosshead joint, also be provided with the groove of annular, be provided with seal ring 5 in this groove.
Fig. 4 is the structural representation of installment state of the present utility model.Can find out, the bent axle 7 of compressor is connected to connecting rod 8, is connected with crosshead 9 at the front end of connecting rod 8, and the front end of crosshead 9 is provided with cross nut 10.
Consisted of piston element 11 after the piston joint of piston rod body 1 is installed piston 6, the piston end of this piston element 11 is positioned at cylinder part 14.Be sheathed between the middle body component 12 in piston element 11 outsides and the cylinder part 14 and be provided with packing elements 13.
The crosshead joint of piston rod body 1 is connected with crosshead 9, and the screw section on the piston rod body 1 front end outer wall is connected with cross nut 10.
Cold oil enters bent axle 7 from oil pump, then enter crosshead 9 through connecting rod 8.Because the crosshead joint of piston rod body 1 front end is inserted in the crosshead 9, and piston rod body 1 front end has O RunddichtringO 5 outward, so can reaching by the oil pipe 2 of piston rod body 1 inside terminal, cold oil then returns from the passage between oil duct inwall and the oil pipe 2, take away simultaneously the heat of piston rod body 1, from the oil drain out oil extraction of piston rod body 1, body divides in 12 in flowing at last again.
