Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, specifically to a self-centering tie rod type ultra-high pressure turbocharger assembly. Background Technology

[0002] Ultra-high pressure boosters are precision devices used to increase the pressure of gases or liquids to extremely high pressures (typically hundreds or even thousands of megapascals). Their core functionality involves multi-stage compression, hydraulic drive, or specialized mechanical structures (such as piston pumps and booster cylinders) to amplify the pressure. They are widely used in petrochemicals, supercritical fluid extraction, high-pressure testing, deep-sea simulation, and materials science. Their design must consider the selection of high-strength materials, sealing technologies (such as metal seals or self-tightening seals), and precise pressure control to address challenges such as media leakage and thermodynamic effects under high pressure. They also incorporate safety valves and real-time monitoring systems to ensure stability. Modern ultra-high pressure boosters are evolving towards intelligent, modular, and energy-efficient designs to meet the demands for high efficiency and reliability under extreme operating conditions.

[0003] Existing ultra-high pressure boosters have the following problems:

[0004] Due to the sealing method, oil and water leakage is quite serious, so most of them are specially designed with an oil leakage hole; the reversing mechanism is poorly designed, the springs are fatigued and often break, the reversing mechanism seat seal often leaks oil, and replacement is also quite troublesome; the high-pressure cylinder is connected by threads, and special tools are required to disassemble the high-pressure cylinder when repairing the turbocharger.

[0005] Furthermore, due to the characteristics of the materials, they will expand and shift under high temperature and pressure, and the threads will often seize up. Once seized up, they are even stronger than welded ones, cannot be repaired, and can only be scrapped. The one-way valve high-pressure three-piece set uses a spherical seal, which is a line seal. Due to water quality, scale will be generated under high temperature and pressure. After scale is generated, it cannot completely seal, causing internal leakage and failing to reach the output pressure. Therefore, a new technical solution needs to be designed to solve this problem.

Detailed Implementation

[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] Example 1: Please refer to again Figure 1-4This utility model provides a self-centering tie rod type ultra-high pressure booster assembly, including a hydraulic cylinder 100. A piston 110 is slidably connected to the inner wall of the hydraulic cylinder 100. Limit plugs 120 are fixedly connected to both ends of the piston 110. Two guide rings 130 are sleeved on the outer side of the piston 110. A sealing plug 140 is sleeved on the outer side of the piston 110. A ceramic rod 150 is fixedly connected to both ends of the piston 110. One end of the ceramic rod 150 passes through the limit plug 120 and extends to the inner side of the guide tube 210. A conical self-centering one-way valve 230 is snapped onto one end of the high-pressure cylinder 200. A water inlet connector 240 is fixedly connected to the outer side of the conical self-centering one-way valve 230. A water outlet one-way valve 250 is screwed onto one end of the conical self-centering one-way valve 230. An A-seat 260 is snapped onto one end of the high-pressure cylinder 200. The A-seat 260 is snapped onto the hydraulic cylinder 100.

[0024] Specifically, the improved sealing design solved the oil and water leakage problem of the original device. The combination of seal 262 and guide sleeve 263, with the inner diameter skeleton oil seal of seal 262 and the outer diameter O-ring, prevented oil pressure leakage. The hard seal between guide sleeve 263 and the end face of high pressure cylinder 200 prevented water leakage into oil cylinder 100. The planar seal of conical self-centering check valve 230 changed the original line seal to a surface seal, which solved the problem of scale formation under high pressure and high temperature and reduced the failure rate of internal leakage.

[0025] Example 2: Please refer to again Figure 1-4 Two high-pressure cylinders 200 are arranged on both sides of the hydraulic cylinder 100. A guide tube 210 is embedded inside the high-pressure cylinder 200. A dynamic seal 220 is snapped onto one end of the high-pressure cylinder 200. A proximity switch 261 is screwed onto the outer side of the A-base 260. A seal 262 is snapped onto one side of the A-base 260. The inner side of the seal 262 contacts the ceramic rod 150. A guide sleeve 263 is snapped onto one side of the seal 262, and the guide sleeve 263 fits against the high-pressure cylinder 200. A B-base 270 is snapped onto one side of the high-pressure cylinder 200. The inner side of the valve is in contact with the conical self-centering check valve 230. Four limiting rods 280 are slidably connected between the outer sides of the two A seats 260. The two ends of the limiting rods 280 pass through the two B seats 270 and extend to the other side of the B seats 270. The outer side of the limiting rods 280 is screwed with a first nut 281, and the first nut 281 is in contact with the A seat 260. The outer side of the limiting rods 280 is screwed with a locking second nut 282, and the second nut 282 is in contact with the B seat 270. One end of the outlet check valve 250 is provided with an outlet valve connector 290.

[0026] Specifically, the original reversing mechanism was replaced by direct sensing, eliminating the spring structure. The reversing mechanism seat was eliminated; the proximity switch 261 (BD3-P1-M14S-732) is threaded onto seat A 260 and directly sensed by the limit plug 120, eliminating the intermediate spring transition and significantly reducing the sensing failure rate. The original reversing mechanism seat was also eliminated, completely avoiding oil leakage caused by the reversing mechanism seat seal. The threaded connections at both ends of the high-pressure cylinder 200 were eliminated. To accommodate the elimination of the threads, the original Flügger type check valve was changed to a self-centering conical check valve structure. This combination of four diagonally distributed limit rods 280, the first nut 281, the second nut 282, and the self-centering conical check valve avoids thread jamming, ensures concentricity with seat A 260, seat B 270, the ceramic rod 150, and the high-pressure cylinder 200, reduces disassembly and installation difficulty, minimizes maintenance downtime, and lowers maintenance costs.

[0027] Working principle: The improved sealing design solves the oil and water leakage problem of the original device. The combination of seal 262 and guide sleeve 263, with the inner diameter skeleton oil seal of seal 262 and the outer diameter O-ring, prevents oil pressure leakage. The guide sleeve 263 and the end face of the high-pressure cylinder 200 form a hard seal, preventing water leakage into the oil cylinder 100. The conical self-centering one-way valve 230 provides a planar seal, changing the original line seal to a surface seal. This solves the problem of scale formation under high pressure and high temperature conditions and reduces the failure rate of internal leakage.

[0028] By using direct sensing, the original reversing mechanism of the device was replaced, eliminating the spring structure. The reversing mechanism seat was eliminated; the proximity switch 261 (BD3-P1-M14S-732) is threaded onto seat A 260 and directly sensed by the limit plug 120, eliminating the intermediate spring transition link and significantly reducing the sensing failure rate. The original reversing mechanism seat was also eliminated, completely avoiding oil leakage caused by the reversing mechanism seat seal. The threaded connections at both ends of the high-pressure cylinder 200 were eliminated. To accommodate the elimination of the threads, the original Flügger type check valve was changed to a self-centering conical check valve structure. The combination of four diagonally distributed limit rods 280, the first nut 281, the second nut 282, and the self-centering conical check valve avoids thread seizing and ensures concentricity with seat A 260, seat B 270, the ceramic rod 150, and the high-pressure cylinder 200. This also reduces disassembly and installation difficulty, maintenance downtime, and maintenance costs.
