Cummins Original Spare Parts Screen 3645469

Material revolution: 316L stainless steel sintered fibre + gradient nickel plating, porosity control in the golden zone of 22±1%

Three-dimensional interception: original "funnel-type" pore size distribution (outer 80μm → middle 50μm → inner 30μm)

System adaptation: precise matching of ISX/QST30 series high-pressure oil pumps, PT injectors and other key parts

1. Plasma-assisted sintering

In a vacuum environment at 850°C, activate the surface energy of the metal through pulsed plasma

Form a homogeneous structure with a pore size tolerance of ±2μm (±10μm in traditional processes)

2. Electrochemical gradient plating

Outer nickel thickness of 15μm, hardness of HV450

Inner nickel thickness of 5μm, to maintain the toughness of substrate materials

3. Laser micropore calibration

Using a 200W 200W fibre optic laser is used for flow through inspection of each filtration unit

Automatic compensation of ±3% flow deviation

Process validation: 99.97% retention efficiency of 20-50μm particles in ISO 4548-12 standard test

1. Desert Mining Equipment

Continuous operation under extreme conditions of fuel oil with sand content of 1.2g/L (exceeding the national standard by 40 times), 500 hours without clogging 500 hours without clogging

Surface oleophobic treatment reduces impurity adhesion rate by 60%

2. Ocean-going ship power

Passed 2000 hours salt spray corrosion test certified by DNV

Special conductive design avoids the risk of explosion of oil mist

3. Polar expedition vehicles

-45℃ low-temperature start-up, the brittle breaking strength of the screen retention rate of 98%

Integrated self-heating module (optional) prevents the clogging of the fuel wax crystals

1. Magnetic Quick Change

Built-in NdFeB permanent magnets, automatic alignment during installation (tolerance ±0.5mm)

Tool-less disassembly and installation

2. Visual Clogging Warning

Transparent viewing window design, equipped with three-colour marking:

Green (ΔP <15kPa)

Yellow (15-25kPa)

Red (>25kPa requires immediate replacement)

3. Ultrasonic Self-Cleaning Interface

Optional Ultrasonic cleaning connector, performance retention rate >95% after 3 times of regeneration

Economy of maintenance: measured data from a logistics fleet shows:

Fuel injection system failure rate reduced by 83%

Precision coupling replacement cost reduced by 62%

Comprehensive maintenance man-hours reduced by 45
