Description

Technical Field

[0001] This utility model relates to the field of dry gas seal replacement technology for large compressors, specifically to an installation platform for training dry gas seal installation. Background Technology

[0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. This achieves the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). Compressors are classified into reciprocating compressors, screw compressors, centrifugal compressors, linear compressors, etc. This entry introduces the working principle, classification, components, specifications, operating requirements, production, common faults, environmental requirements, selection principles, installation conditions, and development trends of compressors. Large compressors refer to those with a displacement greater than 10 μm³. 3 A reciprocating compressor with a speed of [speed per minute]. Mainly used in fertilizer plants and certain integrated enterprises (such as steel-chemical complexes and petrochemical plants). It features strong continuous operation, reliable operation, long service life, good economic efficiency, and convenient manufacturing, installation, and maintenance, as well as easy modification. The main model is the symmetrical balanced type. Mastering the principles and technology of dry gas sealing is of great significance for improving the working efficiency and reducing the cost of large compressors.

[0003] Currently, training on dry gas seals can only be applied to actual maintenance. Correct installation and commissioning are crucial for ensuring the performance of dry gas seals, thereby improving sealing performance and service life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 2This utility model discloses an installation platform for training dry gas seals, comprising a base 1, a fixed bracket 2, a first tray 3, a second tray 5, a sealing chamber 6, an oil baffle 7, a clamping plate 8, fixing screws 11, a sealing spindle 14, a first shaft clamp 15, and a second shaft clamp 17. The bottom end of the fixed bracket 2 is vertically mounted on the base 1. The second tray 5 and the first tray 3 are fixed to the fixed bracket 2 from top to bottom. The sealing chamber 6 is located at the top of the fixed bracket 2. The oil baffle 7 and the clamping plate 8 are overlapped and stacked, and both are fixed to the outer side of the sealing chamber 6 by four sets of fixing screws 11. The sealing spindle 14 is located inside the sealing chamber 6. The first shaft clamp 15 and the second shaft clamp 17 are movably connected to the sealing spindle 14. The installation platform for training dry gas seals is installed using a special tool suitable for even tightening, and the dry gas seal is slowly pushed into the sealing chamber 6 using the screw nuts on both sides. By continuously measuring the distance between the end faces of the special tools on both sides and the end face of the outer end of the sealing chamber 6 while tightening the nut, it is possible to ensure that the dry gas seal enters the cavity of the sealing chamber 6 evenly. When the distance between the end face of the dry gas seal special tool and the end face of the sealing chamber 6 is the same as before assembly, it indicates that the dry gas seal has been installed in place and the unit maintenance can be carried out.

[0024] Please see Figure 3 A first groove 31 is provided on one side of the surface of the first tray 3. The relevant tools (e.g., lead screw nuts) are loaded through the first groove 31, which is not easy to fall off and is convenient to use. A second groove 32 is provided on the other side of the surface of the first tray 3. A machine body support 4 is fixed on the second groove 32, and the required machine accessories can be installed through the machine body support 4.

[0025] Please see Figure 4 The second tray 5 has a third slot 51. The relevant tools (e.g., lead screw nuts) are loaded through the third slot 51, which prevents them from falling off and makes them convenient to use.

[0026] The left and right sides of the sealed chamber 6 are respectively provided with a first balancing ear 9 and a second balancing ear 10 to provide the overall balance performance of the sealed chamber 6; a front isolation seal 12 is provided at the first end inside the sealed chamber 6; a rear isolation seal 13 is provided at the second end inside the sealed chamber 6 to provide the overall sealing performance of the sealed chamber 6.

[0027] Both ends of the first shaft clip 15 and the second shaft clip 17 along the length direction are provided with shaft clip rings. The shaft clip rings can firmly fix the bearing on the first shaft clip 15 or the second shaft clip 17, preventing it from sliding or rotating on the shaft clip, ensuring a seamless connection between the shaft clip and the bearing, and also protecting the bearing from wear or damage due to excessive friction, thereby ensuring the normal operation of the machine and extending its service life.

[0028] The length of the first axle clip 15 is less than the length of the second axle clip 17. The second axle clip 17 has a larger space and better pitch and yaw resistance; the first axle clip 15 has a smaller space and a smaller wheelbase, making it easier to control.

[0029] The first shaft clamp 15 is tightly connected to the sealed main shaft 14 through a first shaft locking sleeve 16, which improves the installation stability of the first shaft clamp 15.

[0030] The second shaft clip 17 is tightly connected to the sealed main shaft 14 through a second shaft locking sleeve 18, which improves the installation stability of the second shaft clip 17.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
