Abstract
The utility model discloses a supplementary installation mechanism of compressor drilled packing ring, including the guide that is used for drilled packing ring centering location, its characterized in that: the guide part is a multi-section structure formed by a plurality of round rods or round rings in an adjacent mode, and the outer diameter of the guide part is the same as the diameter of the piston rod. The utility model discloses can realize the automatic centering of drilled packing ring and piston rod, bear and absorb the impact when the piston rod is installed to realize the nothing of drilled packing ring and hinder the installation, very big improvement installation success rate and installation easy operation nature.
Description
Technical Field
The utility model relates to a compressor, concretely relates to a mechanism for assisting installation of compressor drilled packing ring.
Background
The packing seal component of the reciprocating compressor is generally composed of a packing box and a packing ring, the packing ring sinks and other factors under the action of gravity, in the installation process, as shown in figure 1, the axis of the packing ring 2 and the axis of the packing box 3 are easy to be dislocated, in the process that a piston rod 1 penetrates through the packing ring 2, the piston rod 1 collides with the end face of the packing ring 2, on one hand, the piston rod is blocked, the installation can be completed by large force, on the other hand, the situation that the packing ring is damaged by the piston rod often occurs, and the packing ring group is scrapped or the sealing fails.
Chinese utility model patent CN201925129U discloses an auxiliary device of compressor filler assembly, including locating lever and guide bar, the diameter of locating lever and guide bar is the same with the diameter of piston rod, and the tail end of guide bar has the front end direction tapering of a vertebra hole and locating lever and piston rod to match. When the packing box is used, the positioning rod is firstly arranged in the packing box body to be positioned, the pressing flange is fastened, then the positioning rod is pressed out by the guide rod to play a role in supporting packing, and finally the guide rod is pressed out by the piston rod to finish assembly. The device can utilize the guide rod to support the packing ring, realizes the coaxiality of the packing ring and the piston rod, but in many occasions, the space between the end face of the packing box and the middle body is not enough, so that the long auxiliary installation mechanism cannot be pulled out from the packing box.
Disclosure of Invention
The utility model aims at providing a supplementary installation mechanism of compressor drilled packing ring to realize the installation cooperation of compressor drilled packing ring and piston rod, avoid appearing the ring assembly in the installation and scrap or the sealed inefficacy problem.
In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: the auxiliary installing mechanism for the packing ring of compressor includes one guide part for centering the packing ring, and the guide part is one multi-section structure comprising several adjacent circular rods or rings and has outer diameter the same as that of the piston rod.
According to the preferable technical scheme, the length of each round rod or each round ring is equivalent to the thickness of 2-3 stuffing boxes.
According to a further technical scheme, clamping structures matched with each other are arranged on the adjacent surfaces of the adjacent round rods or the adjacent round rings.
In the technical scheme, the surface of the round rod or the ring which is contacted with the end part of the piston rod during installation is provided with the guide groove which is in taper fit with the front end of the piston rod.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
1. the utility model discloses a guide piece is set up as the supplementary installation mechanism of compressor packing ring, can realize the automatic centering of packing ring and piston rod, bear and absorb the impact when the piston rod is installed, thereby realize the non-invasive installation of packing ring;
2. the sectional structure is adopted, so that the sectional material can be taken out of the stuffing box and removed, and a large installation space is not required;
3. through the guide conical head in front of the piston rod, the central axis of the packing ring is close to the central axis of the piston rod, so that the installation success rate and the installation operability are greatly improved.
Drawings
FIG. 1 is a schematic illustration of an end face impact during installation in the prior art;
fig. 2 is a schematic view of an installation structure of an embodiment of the present invention.
Wherein: 1. a piston rod; 2. a packing ring; 3. a stuffing box; 4. a guide member.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
the first embodiment is as follows:
referring to fig. 2, the auxiliary installation mechanism for the packing ring of the compressor is a guide member 4 with a multi-section structure formed by abutting a plurality of round rods, wherein the outer diameter of the guide member 4 is the same as the diameter of a piston rod 1.
As shown in fig. 2, a plurality of stuffing boxes 3 and corresponding stuffing rings 2 are first mounted on a guide 4, the guide 4 being constituted by a plurality of rods abutting, each rod having a length corresponding to the thickness of 2-3 stuffing boxes. Only one segment of the rod is shown.
The adjacent surface of the adjacent round rods is provided with mutually matched clamping structures so as to ensure the centering state of each round rod. The clamping structure can be a matched conical head, a conical hole structure or a similar mortise and tenon structure.
In order to ensure the centering of the piston rod, a guide groove which is matched with the taper of the front end of the piston rod is arranged on the surface of the round rod which is contacted with the end part of the piston rod.
In this embodiment, the guide may be formed of a multi-stage ring instead of a hollow structure.
Claims (4)
1. The utility model provides a supplementary installation mechanism of compressor filler ring, includes the guide that is used for the centering of filler ring to fix a position which characterized in that: the guide part is a multi-section structure formed by a plurality of round rods or round rings in an adjacent mode, and the outer diameter of the guide part is the same as the diameter of the piston rod.
2. The compressor packing ring auxiliary mounting mechanism of claim 1, wherein: the length of each round rod or each round ring is equivalent to the thickness of 2-3 stuffing boxes.
3. The compressor packing ring auxiliary mounting mechanism of claim 1, wherein: the adjacent surface of the adjacent round rod or the adjacent round ring is provided with mutually matched clamping structures.
