Description

Technical Field

[0001] The utility model relates to a novel compressor oil scraping structure, belonging to the technical field of compressor oil scraping. Background Art

[0002] Compressors are used in the chemical, pharmaceutical, instrumentation, and other sectors where clean, compressed gas is required. When the starting device is turned on, the motor enters normal operation, and the crankshaft, connecting rod, and crosshead cause the piston to reciprocate in the cylinder. When the piston begins to move from the outer stop point to the inner stop point, the outer side of the piston in the cylinder is in a low-pressure state, and gas enters the cylinder through the intake valve. When the piston moves from the inner stop point to the outer stop point, the intake valve closes, and the gas in the cylinder is compressed, increasing the pressure. When the pressure exceeds the gas pressure outside the exhaust valve, the exhaust valve opens and begins to discharge the pressurized gas. When the piston reaches the outer stop point, exhaust is complete and the gas is sent to the next cylinder for compression.

[0003] There are still some problems in the use of existing compressor pistons. When the piston works on the compressor, the lubricating oil will enter the important components of the stuffing box and cylinder along the piston rod. At this time, an oil scraping structure is needed to clean the lubricating oil attached to the surface of the piston. Since the power of compressors of different models is different, the model power of the piston is also different, resulting in different diameters of pistons of different models. The existing oil scraping structure cannot be adjusted according to different models of pistons, which makes it very limited when used with different pistons. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1, please refer to Figures 1-4 , the utility model provides a technical solution:

[0024] The cam 2 is provided with an oil scraping ring 2, and an adjusting rod 3 is slidably connected to the oil scraping ring 2. One end of the adjusting rod 3 passes through the oil scraping ring 2 and extends to the outside of the oil scraping ring 2 and is connected to the oblique oil scraping plate 4 arranged on the outside of the oil scraping ring 2. A caulking oil scraping plate 5 is installed on one side surface of the oblique oil scraping plate 4. The adjusting rod 3 is slidably connected to the oil scraping ring 2 and a limit plate 6 is installed at one end. The limit plate 6 is adapted to the groove opened in the oil scraping ring 2, and the oblique oil scraping plate 4 and the caulking oil scraping plate 5 fit with the compressor piston rod 1.

[0025] Specifically, such as Figure 1 As shown, a plurality of oblique scraping plates 4 and caulking scraping plates 5 are distributed inside the oil scraper ring 2 , and the plurality of oblique scraping plates 4 and caulking scraping plates 5 form a “quasi-arc structure” and are adapted to the compressor piston rod 1 .

[0026] In this embodiment: by setting up the compressor piston rod 1, when the lubricating oil attached to the surface of the compressor piston rod 1 is cleaned, when the compressor piston rod 1 is in the process of movement, the oblique scraper plate 4 and the caulking scraper plate 5 scrape the surface of the compressor piston rod 1, and the caulking scraper plate 5 can form a "quasi-arc structure" with the oblique scraper plate 4, so as to fit more closely to the compressor piston rod 1, thereby achieving a full range of oil scraping treatment for the compressor piston rod 1. When scraping the compression piston rods 1 of different diameters, the adjusting rod 3 on the oblique scraper plate 4 slides inside the stabilizing ring 8 and the scraper ring 2, and the stabilizing ring 8 can support the scraper ring 2 as a whole, so that the device When in use, it is more stable. During the sliding process, the adjusting rod 3 drives the limit plate 6 to squeeze the return spring 7. At this time, the return spring 7 is deformed by the squeezing force. The return spring 7 can assist the inclined scraper 4 and the caulking scraper 5 to perform the reset process, so that the inclined scraper 4 and the caulking scraper 5 return to their original positions. The limit plate 6 can limit the position of the adjusting rod 3 to avoid the position deviation of the adjusting rod 3 during the sliding process, causing the inclined scraper 4 and the caulking scraper 5 to fall off, etc. When the adjusting rod 3 is in the process of sliding, the diameter of the "arc-shaped structure" between the inclined scraper 4 and the caulking scraper 5 is adjusted, thereby adapting to compressor piston rods 1 of different diameters.

[0027] Example 2, please refer to Figure 1 、 Figure 2 and Figure 4The difference between this embodiment and embodiment 1 is that a sleeve ring 9 is symmetrically installed on the surface of the oil scraper ring 2, and the sleeve ring 9 is wrapped around the surface of the compressor piston rod 1. An elastic binding ring 10 is installed at one end of the sleeve ring 9, and the elastic binding ring 10 is sleeved on the surface of the compressor piston rod 1.

[0028] Specifically, such as Figures 1-4 As shown, the elastic binding ring 10 is an elastic component, and the elastic binding ring 10 is made of rubber material.

[0029] In this embodiment: by setting up a compressor piston rod 1, when scraping oil from compressor piston rods 1 of different diameters, the oil scraper ring 2 is sleeved on the compressor piston rod 1, and at this time the ring 9 is sleeved on the compressor piston rod 1, so that the oil scraper ring 2 can be stably sleeved on the surface of the compressor piston 1, and at this time the elastic binding ring 10 is pulled. Since the elastic binding ring 10 is made of rubber material, the elastic binding ring 10 is deformed at this time, so that it can be adjusted when facing compressor piston rods 1 of different diameters, so that the elastic binding ring 10 is tightly sleeved on the surface of the compressor piston rod 1, and then the oil scraper ring 2 is tightly sleeved on the compressor piston rod 1. At this time, the oil scraper ring 2 is installed inside the compressor, which further improves the effect of adjusting compressor piston rods 1 of different diameters.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
