Description
Technical field
Vertical compressor technical field of structures is the utility model is related to, specially a kind of vertical compressor high temperature piston knot
Structure.
Background technology
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to gases at high pressure, can be divided into piston compression
Machine, helical-lobe compressor, centrifugal compressor, linear compressor etc., wherein vertical piston compressor are common the vertical cloth of piston
Put, need to connect by crosshead between the piston rod and connecting rod of piston, when being compressed using high temperature gas medium, need
Cooling body is set on the compressor, using lubricating oil come to carry out cooling be one way in which, but existing piston rod
For a solid body of rod, cooling can not be realized, has influence on the use of compressor.
The content of the invention
For the solid body of rod of existing compressor piston rod, the technical problem the utility model that can not be cooled down provides a kind of vertical
Formula compressor high temperature piston structure, it can be cooled down by lubricating oil, it is ensured that the normal use of compressor.
Its technical scheme is such：A kind of vertical compressor high temperature piston structure, it includes piston head and connection institute
State the piston rod of piston head, it is characterised in that cooling oil cavity is provided among the piston rod, the cooling oil cavity is remote
It is open-ended from the piston head, middle dry pipe, the middle dry pipe and the piston rod are provided with the cooling oil chamber body
Inwall leaves space and forms oil circuit, and the piston rod is provided with entering for the oil circuit on the lateral wall away from the piston head side
Hydraulic fluid port, the middle dry pipe between described piston head one end and the piston rod inwall away from being provided with Sealing shield ring.
It is further characterized by, and the piston head includes the piston gland that piston bush is fixedly connected with both ends；
Clearance adjusting pad is provided between the piston rod and the piston head；
The piston rod outer peripheral face is provided with the oily component of gear.
After structure of the present utility model, lubricating oil is sent into from oil inlet, flows through after oil circuit again going out for therefrom dry pipe
Mouth down flows out, and piston rod is integrally cooled down, Sealing shield ring ensure that sealing, easily realize cooling, it is ensured that
The normal use of compressor.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
As shown in Figure 1, a kind of vertical compressor high temperature piston structure, its work for including piston head 1 and connecting piston head 1
Stopper rod 2, cooling oil cavity 3 is provided among piston rod 2, cooling oil cavity 3 is in open-ended, the cooling oil chamber away from piston head 1
Middle dry pipe 4 is provided with body 3, middle dry pipe 4 leaves space with the inwall of piston rod 2 and forms oil circuit 5, and piston rod 2 is away from living
Be provided with the oil inlet 6 of oil circuit 5 on the lateral wall of the side of chock plug 1, middle dry pipe 4 away from the one end of piston head 1 and the inwall of piston rod 2 it
Between be provided with Sealing shield ring 7.
Piston head 1 includes the piston gland 1-2 that piston bush 1-1 is fixedly connected with both ends；Between piston rod 2 and piston head 1
Clearance adjusting pad 8 is provided with, there can be small free gap；The outer peripheral face of piston rod 2 is provided with the oily component 9 of gear, plays gear oil
Effect.
