Tips – What Should I Do When We Meet These Problems In Mechanical Maintenance?

Although the mechanical surface looks very hard, the internal components are actually very fragile. If the maintenance is not proper, it is very easy to have problems. Many people have many wrong practices in the process of repair, which affects the normal use of construction machinery. Therefore, we collected some maintenance issues so that everyone can properly maintain the machinery.


1.Cannot correctly judge analysis failure


Some maintenance personnel are unclear about the structure and principle of the construction machinery. As a result, not only the original fault has not been eliminated, but also new problems have arisen. Therefore, when the machine fails, the maintenance personnel must test through the testing equipment, combined with the structure and working principle of the engineering machine to determine the fault location.


2.Replacement parts


The judgment and elimination of engineering machinery failures is relatively difficult. Some maintenance personnel have always adopted the method of replacement test, regardless of the large and small pieces, as long as it is considered that it may be the component that caused the failure, one by one replacement test. As a result, the fault was not ruled out, and the parts that should not be replaced were replaced at will, which increased the cost of the consumer.


3.Can not check the quality of new parts

Before replacing the parts, some maintenance personnel do not perform technical inspections on the new parts and directly install them on the construction machinery. This is unscientific. The quality of spare parts currently on the market, if not tested, often causes failures after assembly.


4.Will ignore the accessory model

When repairing construction machinery, the substitution or misuse of accessories is still common. Some accessories are feasible for emergency use, but long-term use is harmful and affects the safety and technical performance of the machine.


5.Maintenance method is not regular

When repairing construction machinery, some maintenance personnel do not take correct maintenance methods to “maintenance” and “maintenance”. It is necessary to fundamentally identify the cause of the failure and take a formal maintenance method to eliminate the fault, which should be brought to the attention of the mechanical maintenance personnel.


6.Do not pay attention to the quality of small pieces

During maintenance work, some maintenance personnel often only pay attention to the maintenance of parts such as transmission chain, oil pump, hydraulic oil pump, brake, lubrication system, etc., but neglect the maintenance of “small pieces” such as filters and various instruments.


7. Forget some maintenance taboos

When repairing construction machinery, some maintenance personnel do not understand some problems. As a result, “habitual” errors often occur in disassembly and assembly, which affects the quality of mechanical maintenance.


8. Decontamination and cleaning of parts

When repairing construction machinery, it is important to properly remove the oil stains and impurities on the surface of the parts to improve the repair quality and extend the service life of the machine. Failure to pay attention to the cleaning of the parts may result in early wear and corrosion of the parts.
