Description
Product Overview
The high-pressure connection rod is assembled between the high-pressure common rail oil pipe and the injector body, serving as a dedicated high-pressure fuel flow channel capable of continuously and stably delivering fuel to the internal injection components. Under long-term mining conditions of 24-hour heavy-duty high-pressure impact, cabin alternating high-temperature and low-temperature vibrations, and continuous impaction of impure diesel, the rod's threaded surface may be scratched, the sealing step may wear out, and the sealing rubber ring may age and harden. This may result in high-pressure fuel leakage, rapid pressure relief of the pipeline rail, and equipment exhibiting idle vibration, weak climbing power, difficulty in restarting after engine shutdown, and incorrect fault lights indicating errors. This product has standardized processing for the total length of the rod body, the threaded specification, and the outer diameter of the limit step. After disassembling the cylinder head oil circuit, the connection rod can be replaced alone to repair high-pressure leakage faults. It is suitable for large mining excavators, heavy-duty wheeled loaders, and long-distance heavy-duty freight trucks for the maintenance and repair of electrically controlled common rail diesel engines.
Core advantages of the single product
The high-pressure alloy steel is formed by a single cutting process, and the high-pressure bearing capacity is not prone to deformation or cracking.
The entire high-temperature quenched alloy steel is an integrated long rod structure without splicing. The surface is treated with black passivation for rust prevention and wear resistance, capable of enduring extremely high pressure fuel impacts continuously. It is not prone to bending, cracking, or oil leakage under alternating high and low temperatures and vibrations, maintaining the stability of the high-pressure oil circuit base oil pressure.
The middle limit step + pre-installed integrated sealing rubber ring provide dual barriers against fuel leakage.
The middle section of the rod body has a raised limit positioning step, and it is paired with a pre-installed oil-resistant fluorine rubber sealing O-ring. During assembly, it is precisely positioned, and the installation gap of the cylinder head is precisely filled, completely blocking the leakage of high-pressure fuel through the assembly gap, avoiding pressure loss in the oil circuit due to intake.
The rear end is precisely rolled to form an external thread, which bites tightly and is not prone to slippage.
The tail end has a standard rolled external thread, with the pitch and outer diameter tolerances strictly controlled. After tightening, the fit is high, and there is no oil leakage through the thread gap under high-pressure conditions. After multiple disassemblies and reassemblies, it is not prone to slippage or damage to the threaded sealing surface.
The front end has a conical guide tip, ensuring smooth fuel flow without impurities accumulating and blocking the oil passage.
The head has a smooth conical guide structure, with a smooth transition of the oil passage, reducing the resistance of the high-pressure fuel flow and reducing the accumulation and blocking of diesel impurities in the oil circuit, ensuring the continuous and stable supply of fuel under heavy-load and high-load conditions.
The rod body is laser-engraved with identification codes for recognition, enabling quick matching of models during storage and maintenance.
The rod body is engraved with multiple sets of part identification codes, resistant to diesel soaking and repeated wiping without the characters falling off. During inventory storage, on-site disassembly and assembly, it is easy to distinguish specifications and models, eliminating abnormal rail pressure and insufficient power faults caused by incorrect installation.
Each connection rod is independently tested for high-pressure pressure retention before leaving the factory, and no secondary grinding or adjustment is required during assembly.
Each connection rod is independently completed with high-pressure pressure sealing and fuel flow rate testing. The factory size and performance parameters are unified, directly matching the corresponding injector cylinder head installation holes, significantly reducing the time for oil circuit disassembly, assembly, and debugging.
