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 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.

The fuel injection pump is a core component of the engine, making daily maintenance critical. When the fuel injection pump malfunctions, how should it be repaired? In the following, I will explain common fault cases and troubleshooting methods for excavator fuel injection pumps.Fault 1: Diesel mixing with engine oil. This issue is typically caused by wear of the injection pump, manifested by an increase in oil volume with a strong diesel odor.

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.

The primary differences between Komatsu original (OEM) filters and aftermarket filters lie in their quality, performance, and cost.Quality and Materials: OEM filters are made by Komatsu or approved manufacturers, ensuring they meet the company's strict design and quality standards. They are built to last and offer optimal filtration capabilities, protecting sensitive machinery parts like engines and hydraulic systems.

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.

Hydraulic pumps play a vital role in numerous industrial and engineering applications, serving as a fundamental component where hydraulic power needs to be efficiently transferred. Understanding the functions and significance of hydraulic pumps is crucial for appreciating their essential role in modern industry.One of the primary functions of hydraulic pumps is to generate hydraulic pressure, which is indispensable for various industrial processes like the operation of heavy machinery and the movement of large objects.

Choosing the right hydraulic pump is crucial for the performance and stability of the hydraulic system. So, how do you choose the appropriate hydraulic pump? This article will provide you with a comprehensive guide to help you easily navigate the selection of hydraulic pumps.First and foremost, it is essential to clarify the requirements.
