Summer has arrived many timesUsed excavatorFaced with more challenges, temperature issues during use are the most common and complex fault problems. High temperatures not only cause frequent failures of second-hand excavators, but also result in serious losses due to their inability to function properly. High temperature problems generally occur in older second-hand excavators, and the triggering rate of failure increases with age.
Many customers have resorted to removing the engine cover to cool down the engine or hydraulic system in the face of general high temperature problems. This method only treats the symptoms but not the root cause. There are many types of high temperature problems that can be caused by heat dissipation or hydraulic pumps. It is generally recommended to clean the water tank or replace the hydraulic oil to solve the problem. The most appropriate method is to consult an experienced professional. Do not disassemble large parts without identifying the fault problem, which may cause additional component damage.
Another common issue in second-hand excavators is the problem of stuck engines. The problem of stuck engines can be divided into several types. Nowadays, in the competition between mainstream electronic fuel injection machines and direct injection machines, stable direct injection has become a mainstream trend in the engineering machinery market to meet the standardized displacement of electronic fuel injection. The failure rate of fuel injector solenoid valves is also one of the main reasons for stuck engines. Don't deal with problems casually. Please have a professional technician test such problems. With the innovation of random technology, most fuel injector problems can be resolved through calibration, rather than just spending a lot of money to replace them with new ones.
Second hand excavators, whether old or new, require professional and meticulous maintenance to maximize their value. The problems caused by cheap or arbitrary disassembly of parts are the most fatal. At present, there are many brands of excavator accessories on the domestic market, although it is not necessarily necessary to purchase original ones. However, when purchasing and maintaining accessories, careful consideration must be given, as problematic accessories, especially large maintenance accessories, can cause the most serious problems. There are ways to eliminate any faulty issues with second-hand excavators. Without the inspection of professional technicians, please do not judge the problem arbitrarily.
