Utilizing 180℃ high-temperature enameled wire, the heat resistance is significantly enhanced. The stator poles, crafted from 10# steel with excellent magnetic conductivity, ensure optimal product performance and stable magnetic field distribution.

This mechanical high-pressure diesel pump stands out with its key strengths. Its precision plunger pairs enable accurate high-pressure fuel delivery, boosting combustion efficiency. The heat-treated high-strength alloy pump body withstands 160MPa pressure, ensuring durability. The mechanical adjustment mechanism adapts to various conditions for stable fuel supply, optimizing power and economy. With a pure mechanical design, it operates reliably in harsh environments, reduces maintenance hassle, and cuts costs.

FILTER

ROCKER ARM

The oil filter features high-precision composite filter paper, while the diesel filter is equipped with nano-grade filtration material. Both ensure exceptional filtering accuracy and are encased in corrosion-resistant shells, effectively extending service life and replacement intervals.

Using segmented quenching technology, this rocker arm precisely treats different parts. Critical stress points reach HRC58 - 62 for high wear resistance and anti-deformation, while non-stressed areas stay tough to prevent fractures. With a balance of strength and flexibility, it maintains stable performance during high-frequency swings, offering 40% longer lifespan than traditional ones, ensuring reliable support for engine valve systems.
