Description
Product Overview
The 6N7527 plunger is the core pressure component inside the fuel pump. It uses the reciprocating motion of the straight rod plunger to establish high fuel pressure, providing a stable oil pressure support for the entire fuel supply system. After long-term high-load operation, the plunger is prone to wear and pressure leakage, or jamming. This component can directly replace the damaged parts to restore the constant fuel supply pressure of the equipment, ensuring smooth and continuous engine power output.
Unique features of this single product
Integrated solid straight rod plunger, with high coaxiality and no wear
The overall solid straight rod structure has strict processing coaxiality control, and the plunger's reciprocating motion will not cause unilateral friction with the cylinder, significantly reducing the internal wear rate. Long-term operation is less likely to have increased gaps or oil leakage problems.
Double-layer stacked buffer springs, good buffering and shock absorption effect
The design of an internal and external double-layer spring combination reduces vibration and noise caused by the plunger impact during fuel pumping, and also weakens the oil pressure shock, alleviating the fatigue wear of the internal components of the pump body.
Thickened ring-shaped pressure-bearing base, dispersing oil pressure impact force
The bottom is widened and thickened to increase the contact area of the oil pressure, dispersing the instantaneous impact force brought by the high-pressure fuel, and the base is less likely to deform or crack, suitable for long-term full-load continuous operation conditions.
Overall surface hardening treatment, resistant to oil stains and corrosion
The entire plunger, spring, and base are treated with hardening and wear-resistant processing. In the environment of construction diesel, dust, and moisture, they are less likely to rust or corrode, and the surface will not have spots or peeling, ensuring stable clearance.
Integrated complete set without disassembly, high maintenance and assembly efficiency
The entire set of components has been pre-installed at the factory, and the gap between the spring, plunger, and base has been adjusted properly. During maintenance, the entire set can be directly installed into the pump body, without the need to assemble individual components, eliminating the need for repeated adjustment and matching procedures. Applicable scenarios
Compatible with the corresponding series of diesel fuel pump assemblies. Widely used in loaders, mining machinery, fixed power generation equipment, and engineering heavy machinery. Suitable for the maintenance and replacement of the fuel supply system in high-temperature and dusty working environments such as construction sites, mining areas, and outdoor factory sites.
