Abstract
A through piston-rod guiding support device with adjustable radial position comprises a front coupling sleeve, a supporting seat, a guiding bush and adjustable parts. The front coupling sleeve is connected with the cylinder of air compressor by the connecting bolts. The supporting seat is mounted in the front coupling sleeve via the adjustable parts. The guiding bush is fixed in the center hole of the supporting seat in the mode of interference fit. The radial position adjustable parts are arranged at two or more positions between the front coupling sleeve and the supporting seat. The adjustable part can be a group of adjusting screws, or gaskets. During installation or overhaul or after a period of operation, the radial position of the supporting seat and the guiding bush in the front coupling sleeve can be adjusted through the adjustable parts. The axial orbit during the motion of piston rod and the center line of the cylinder is ensured to coincide. By using the device, not only the maintenance cost for compressor and the consumption can be reduced, but also is helpful for the safe, stable and long period of operation of the machine set.
Description
The utility model patent relate to a kind of adjust radial position run through piston rod guided bearing device.
At present, run through in the reciprocating compressor of piston rod in use, exist following three kinds of piston rods guiding and supporting structure: 1, the piston rod two ends are all by cross-head guide and supporting; 2, piston rod one end is by cross-head guide and supporting, and the other end is by fixing guide bush guiding and supporting; 3, piston rod one end is by cross-head guide and supporting, and the other end does not have guiding and bearing device.Above-mentioned three kinds of structures not only first kind of structure will cause the compressor arrangement complexity, machines cumbersome, and energy consumption increases, and all has the high and difficult shortcomings such as radial position of adjusting piston rod of the machining accuracy that requires each related components.When installing or overhauling, especially after moving a period of time, axis line track and cylinder centerline when being difficult to guarantee piston rod movement coincide, easily cause the quick wearing and tearing between packing elements and cylinder minute surface and the piston assembly, even cause piston rod to bear additional complicated alternating stress and rupture, safe, stable, the long-term operation of compressor constituted a serious threat.
The utility model is intended to avoid the disadvantages of background technology part, provide a kind of axis line track and cylinder centerline can guarantee piston rod movement by easy adjustment in good time the time to coincide, and simple in structure, the easy to operate radial position adjusted run through piston rod guided bearing device.
Realize that main technical schemes of the present utility model is: a kind of adjust radial position run through piston rod guided bearing device, it is made up of preposition extend neck, supporting base, guide bush and tunable component.Preposition extend neck uses attachment bolt to be connected with compresser cylinder, and supporting base is installed in the preposition extend neck by tunable component, and guide bush adopts the mode of interference fit to be fixed in the center hole of supporting base.Between preposition extend neck and supporting base two or two are provided with the radial position tunable component with upper position, can adjust supporting base and the radial position of guide bush in preposition extend neck by adjusting tunable component.The tunable component that is used for adjusting supporting base and guide bush radial position can be one group of adjusting screw, also can be one group of pad.
When installing or overhauling and after operation a period of time, adjust supporting base and the radial position of guide bush in preposition extend neck by adjusting tunable component, axis line track and cylinder centerline in the time of can guaranteeing piston rod movement coincide.
The utility model is compared with background technique has following advantage: adopt safe and reliable, simple method that axis line track and cylinder centerline when running through piston rod movement are coincided, to alleviate the wearing and tearing between packing elements and cylinder minute surface and the piston assembly, improve filler and the sealability of piston ring and the working life of packing elements, piston assembly and cylinder, thereby both reduced the maintenance expenses of compressor, reduce consuming, safe, stable, the long period that help unit again well move.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of reciprocating compressor cylinder assembling schematic representation that adopts an embodiment of the present utility model.(Figure of abstract)
Fig. 2 is adjusting screw and the radially direct schematic representation of nut in preposition extend neck among Fig. 1.
In the drawings, 1, crosshead 2, crosshead slideway 3, piston rod 4, middle extend neck 5, packing elements 6, piston assembly 7, cylinder assembly 8, adjust nut 9, adjusting screw 10, preposition extend neck 11, bearing support 12, guide bush
As shown in Figure 1, crosshead slideway (2), middle extend neck (4), cylinder assembly (7) and preposition extend neck (10) connect firmly together successively with attachment bolt, supporting base (11) is installed in the preposition extend neck (10) by adjusting screw (9), and nut (8) compresses adjusting screw (9) in case it is loosening with adjusting.Guide bush (12) then adopts the mode of interference fit to be fixed in the center hole of supporting base (11).During compressor operating, piston rod (3) is under the guiding and supporting role of crosshead (1) and guide bush (12), by crosshead (1) traction and drive piston assembly (6) and move in the active chamber that filler assembly (5) and cylinder assembly (7) are formed.As shown in Figure 2, four supporting planes that adjusting screw (9) is installed in the present embodiment are arranged on four radial positions in upper and lower, left and right in the preposition extend neck (10).When installing or overhauling and after operation a period of time; can adjust supporting base (11) and the radial position of guide bush (12) in preposition extend neck (10) by adjusting nut (8) and adjusting screw (9); make crosshead (1) and guide bush (12) the longitudinal center line of piston rod (3) of common guiding and supporting and the longitudinal center line of cylinder assembly (7) coincide; thereby axis line track and cylinder centerline when guaranteeing piston rod (3) motion coincide; packing elements when alleviating compressor operating (5) and piston rod (3) with this; mutual wearing and tearing between cylinder minute surface and the piston assembly (6) increase substantially packing elements (5); the usability and the life-span of piston assembly (6) and cylinder.
Claims (3)
- That 1, can adjust radial position runs through piston rod guided bearing device, form by preposition extend neck, supporting base, guide bush and tunable component, it is characterized in that: preposition extend neck uses attachment bolt to be connected with compresser cylinder, supporting base is installed in the preposition extend neck by tunable component, and guide bush adopts the mode of interference fit to be fixed in the center hole of supporting base.
