Description
Product Overview
6261-71-1220 High-pressure Common Rail Tube is the core component for stabilizing and distributing pressure in multi-cylinder diesel common rail systems. The high-pressure pump delivers fuel into the internal rail body for pressure stabilization and pressure storage, then evenly distributes it to each cylinder injector. When the old oil rail experiences internal wall rusting, interface leakage, pressure stabilization failure, or sensor base oil leakage, the entire set replacement can stabilize the fuel pressure supply for the entire cylinder, suitable for large-scale six-cylinder mining engineering machinery and heavy-duty diesel generator sets for major overhauls and replacements.
Unique Core Features of the Individual Product
Aluminum casting integrated long rail body, stable pressure storage and stabilization effect
Overall die-casting seamless cavity, smooth internal channels without burrs, the high-pressure fuel enters and buffers and stabilizes the pressure, the oil pressure difference between each cylinder is small, heavy-load acceleration will not cause insufficient fuel supply for a single cylinder or power break.
Six independent oil outlet interfaces, equipped with yellow protective plugs
The rail body evenly arranges 6 sets of standardized oil outlet threaded connections, factory pre-installed with yellow dust-proof protective caps, during transportation and storage, dust and impurities are isolated, avoiding impurities entering the oil circuit and causing the injector to get stuck.
Dual integrated function installation base, compatible with sensors and pressure relief valves
One side of the rail body reserves two dedicated installation bases, respectively used for assembling pressure sensors and pressure relief valves, the integrated molding does not require additional adapter blocks, reducing the number of pipeline connection points and reducing the risk of high-pressure leakage.
Both ends are sealed and thickened heads, less prone to deformation and cracking under high pressure
The thickened head structure at both ends of the oil rail disperses the internal high-pressure impact force, under long-term continuous 40MPa or higher high-pressure conditions, the rail body will not bulge or crack, and the overall pressure-bearing durability is higher.
Standard fixed installation holes reserved on the side, convenient assembly alignment
Both ends of the rail body reserve positioning installation holes, can be directly locked and fixed with screws on the engine cylinder block, assembly positioning is accurate, the oil rail is less likely to shift under equipment vibration, and the threaded interface is less likely to loosen and leak. Applicable scenarios
Compatible with six-cylinder high-displacement heavy-duty diesel power, mainly used in large mining excavators, heavy-duty loaders, mining excavation equipment, and high-power fixed diesel generators. Suitable for oil circuit system replacement in all-weather high-temperature and high-dust continuous heavy-duty working conditions in mining areas and construction sites.
