Description
Product Overview
The high-pressure connection rod is installed between the common rail oil pipe and the injector, serving as a high-pressure fuel flow channel, continuously delivering thousands of bar of high-pressure fuel to the internal injection components of the injector. Under long-term conditions of heavy mining high-pressure impact, cabin high-temperature vibration, and impure diesel erosion, the rod body's threads may be scratched, the sealing steps may be worn, and the rod body may deform. This can lead to high-pressure fuel leakage, rapid pressure loss in the rail, and equipment experiencing idle vibration, weak climbing power, and difficulty in restarting after shutdown. This product has standardized specifications for rod length, thread size, and limit step outer diameter. After disassembling the cylinder head oil circuit, the connection rod can be replaced alone to repair the high-pressure leakage fault. It is suitable for large mining electric control common rail diesel engines for maintenance of large mining excavators, heavy-duty loaders, and long-distance heavy-duty freight trucks.
Core advantages of the product
The high-pressure alloy steel is formed by a single cutting process, and it is not prone to deformation or cracking under high-pressure bearing.
The overall high-temperature quenched alloy steel material, with a single continuous rod structure without splicing, is treated with black passivation for rust prevention and wear resistance, and can withstand extremely high pressure fuel impact for a long time. It is not prone to bending, cracking, or leakage under alternating cold and hot vibrations.
The central integrated limit and sealing step precisely positions and matches the sealing gasket.
The raised limit step in the middle section of the rod body precisely positions during assembly, and when combined with the matching sealing gasket, it completely fills the installation gap of the cylinder head, blocking the leakage of high-pressure fuel through the assembly gap, stabilizing the oil pressure of the common rail pipeline.
The rear end has precisely rolled outer threads, with a tight and non-slipping sealing fit.
The tail end has a standard rolled outer thread, with regular tooth shape and precise tolerance, ensuring a high degree of fit after tightening, and preventing oil leakage through the thread gap under high-pressure conditions. It is easy to disassemble and reuse without slipping damage.
The pointed front end has a flow guiding structure, ensuring smooth fuel flow without vortex blockage.
The conical guiding head at the front end has a smooth transition of the oil passage, reducing the resistance of high-pressure fuel flow and reducing the accumulation of impurities in the oil passage, ensuring continuous and stable fuel supply under heavy load conditions.
The outer wall is laser engraved with multiple identification codes, facilitating quick matching of the model during storage and maintenance.
The rod body is engraved with multiple part identification codes, resistant to diesel soaking and repeated wiping without fading, enabling quick differentiation of specifications during maintenance, on-site disassembly, and assembly, and preventing abnormal oil pressure faults caused by incorrect installation.
Each piece has independent high-pressure pressure retention testing, and no secondary grinding and adjustment are required during assembly.
Each connection rod is individually subjected to high-pressure sealing testing on the machine, with uniform size parameters, directly matching the corresponding injector installation hole position, significantly reducing the assembly, disassembly, and debugging time of the cylinder head oil circuit. List of Accessories
F00RJ01029 High-pressure injector connection long rod 1 piece Applicable scenarios
It is suitable for large mining excavators with high-pressure common rail fuel supply system, heavy-duty wheeled loaders, long-distance heavy-duty freight trucks, and high-power fixed diesel generators.
