The problem of engineering machinery failures has always been a major headache for some new machine owners, and troubleshooting and maintenance are essential steps for engineering machinery. In daily use, when it comes to maintenance, if there is a master who is knowledgeable or familiar with the equipment and can completely solve the problem for the customer, then how to solve the fault problem is not something that ordinary drivers can handle. When encountering a fault, the first thing to do is to find a repairman and then go through a lot of trouble to completely solve the problem. Not to mention the unnecessary cost of teaching tuition, it is inevitable.
How to identify the fault and the possible location of the fault in the first time when a problem occurs? The basic faults of excavators are mainly related to the three major components and problems in the circuit and oil circuit. Blindly repairing and wasting money will definitely cost more. The replacement of some small accessories can completely solve the problem, which is exaggerated and rendered, resulting in various disassembly and testing costs, not to mention a lot of money, and the delay time is also extremely long. In terms of engine malfunction, it can be easily identified. If properly maintained, there will be no significant damage to the internal structure. However, if there are problems with replacing vulnerable parts, troubleshooting and solving the problems are very simple. For hydraulic systems, if there are major problems, don't listen to the repairman's instructions on how to repair and detect them. It costs a lot of money to repair them, as the price of hydraulic pumps is not high nowadays. Some hydraulic system assemblies for medium-sized equipment are also available1About ten thousand. Replacing is always more thorough than repairing. If hydraulic pumps are not repaired by professional technicians, the failure rate in the short term and later period will also be frequent, which is not cost-effective. If it's just a simple minor issue here, of course, replacement and repair should be the main focus.
The vast majority of circuit failure issues occur in the external circuit system, and the computer version of the excavator has an extremely low failure rate as long as it does not enter water. Excluding some repair workers who make a mountain out of a molehill, it is necessary to seek professional technicians for circuit system repairs. Many lazy mechanics get away with circuits, and if not handled properly, later failures and equipment problems can be very serious.
Oil circuit problems are simpler and easier to deal with. The replacement of pipelines and the connection of interfaces can be clearly seen, but the price is known by many machine owners. After the pipeline is replaced, many bosses still have problems in the later stage of management or often encounter them due to cost control or simply trying to save money. Some core components can be used from the original factory, and the materials and quality control of accessory parts from the secondary factory do not meet the standards required by the manufacturer.
The problem of excavator malfunction requires the main door to spend more leisure time at home exploring and researching, which can save a lot of costs and time. Of course, maintenance and upkeep are the most fundamental preventive measures. Only through meticulous maintenance can problems be avoided in the later stages, which means spending a small amount of money to avoid suffering. It is often oneself who tries to save money and deceive others.
