Construction Machinery Fuel Pump, is a core component of the engine lubrication system. It is responsible for pressurizing and delivering engine oil to moving parts such as crankshafts, camshafts and connecting rods, forming an oil film to reduce friction and wear, while removing heat and impurities, ensuring stable operation of the engine under heavy-duty and harsh working conditions such as mines and construction sites. The pump housing is made of high-strength aluminum alloy, integrally formed by low-pressure casting with dense structure, light weight and excellent heat dissipation performance, which can effectively reduce the weight of the upper part of the engine and improve heat dissipation efficiency. The surface is shot-blasted with good rust and corrosion resistance. The internal gears are made of high-quality alloy steel, strengthened by multiple heat treatment processes such as forging, quenching and tempering, and high-frequency quenching, with high hardness, excellent wear resistance and fatigue resistance, which can withstand meshing wear at high speeds for a long time, greatly extending the service life. Key mating surfaces such as gears and journals are precision polished/ground with high dimensional accuracy and low surface roughness, with reasonable fit clearance, ensuring stable oil pressure output and preventing engine failure caused by insufficient oil pressure.
The product has passed strict oil pressure test and sealing performance test to ensure stable operation under high temperature and high pressure environments, preventing oil leakage and pressure fluctuations. At present, this model of oil pump is in stock, which can quickly respond to orders and provide stable supply guarantee, making it an ideal accessory for the maintenance and repair of Caterpillar excavators in mining, construction, water conservancy and other fields.
