When it comes to Japanese imported machines, the Komatsu excavator stands out for its exceptional performance and durability, winning the hearts of machine enthusiasts in the Chinese market. However, regardless of the series, after thousands of hours of operation in various construction environments, Komatsu excavators encounter the challenge of adjusting the hydraulic pump.

Check whether the diesel pump pump body oil leakage: check whether the diesel pump seals (gaskets, oil seals, etc.) is damaged or aging, if there is damage or aging need to replace the relevant parts in a timely manner.Check whether the parts of the diesel pump are worn: open the diesel pump, carefully check the surface of the pump parts with or without obvious wear, if there is wear parts need to be replaced in a timely manner and to ensure that the installation is correct.Replace the diesel pump seals: disassemble the diesel fuel, open the pump body, find the aging hardened seals and replace

When operating excavators, one of the most common issues faced is abnormal increase in diesel consumption or burning oil. This not only raises equipment operating costs but also leads to equipment wear and failure. To address this issue, it is crucial to identify the root causes of increased fuel consumption or burning oil.Excessive Wear of Components: The wear of the piston, piston ring, and cylinder liner can cause oil to escape into the combustion chamber, leading to a sharp increase in oil consumption.

Injector troubleshooting methods1. Few or no oil injected by the injector.2. Injector injection pressure is too low.3. Injector injection pressure is too high4. Leakage of fuel injector injectors5. Poor atomization of fuel injector injection6, Injector injection into the line7, Injector needle valve surface burned or blue-black color. Note: (diesel engine overheating) check the cooling system, and pay attention to the replacement of coupling parts.

This includes determining the type of cartridge (air filter, oil filter, fuel filter, hydraulic filter, etc.), size (filter inner diameter, outer filter size, and head and tail size), cartridge material (filter paper material, housing material, internal parts material, different materials correspond to a different price), weight, packaging and so on.

The quality of fuel injectors is heavily influenced by the materials used in their construction, which directly affect their durability, performance, and cost. Here are the key material differences found in fuel injectors of varying qualities:1. Housing and Body MaterialHigh-Quality Injectors: Typically made from stainless steel or high-strength alloys.
