At the current stage, due to the reduction in the number of large-scale projects in the transformation of the National Economic Policy, excavator owners in various places have very little work to do, and even if there is a price, it is relatively low. How to reduce the cost of excavating machinery and increase revenue is the main requirement of current excavator users.

1. Minimize the existence of some objective factors that are not conducive to the work of the excavate machine. The structural principle, disassembly and installation methods, fault diagnosis and elimination methods of maintenance excavator , especially the general and typical fault diagnosis, elimination methods and disassembly of excavator parts are introduced in detail.
A. The structural principle, disassembly and installation methods, fault diagnosis and elimination methods of maintenance excavator , especially the general and typical fault diagnosis, elimination methods and disassembly of excavator parts are introduced in detail. For engineering machinery working in harsh environments and complex conditions, first of all, use high-quality, matching components and lubricating oils and greases to block the source of harmful impurities; secondly, do a good job of mechanical protection at the work site and corresponding institutions It can work normally to prevent various impurities from entering the machine. As far as possible, repair the faulty machinery to a regular repair place. When repairing on site, also take protective measures to prevent parts replaced during field repair from being contaminated by impurities such as dust before entering the machine.
B. During the use of construction machinery, one must prevent overload operation at low temperatures and normal operation at the low-speed pre-heating stage, so that the machinery can reach the prescribed temperature before driving or working. Do not ignore its important role because no problems occurred at the time; To prevent the machine from running at high temperature, the values on various thermometers should be checked frequently during the machine's operation. If a problem is found, the machine should be stopped immediately for inspection, and the fault should be removed in time. For those who cannot find the cause for a while, they must not make the machine work without treatment. In normal work, pay attention to check the working condition of the cooling system. For water-cooled machinery, you must check and add cooling water before working daily. For air-cooled machinery, you must regularly clean up the dust on the air-cooled system, and the cooling air duct is unobstructed.
C. In use, the management and operating personnel must take effective measures to reduce the impact of chemical corrosion (interpretation: refers to decay, disappearance, erosion, etc.) on the machine according to the local weather conditions and air pollution conditions at that time, with emphasis on preventing rain and air Chemical intrusion into machinery.

2. Strictly control the good power of the excavating machinery when working strictly and overload operation.
The size and nature of the working load have an important influence on the process of mechanical wear. In general, wear of a part (a basic type of component failure) increases proportionally with increasing load. When the load on the part is higher than the average design load, its wear will increase. In addition, under the same other conditions, the stable load is less abraded than the dynamic load, with fewer failures and lower life.
The normal working load mainly depends on the use of construction machinery by the operator. Excavator repairs are replacement parts, pure repair parts, functional repairs, maintenance and restoration, maintenance, repair, and repair. Improving the technology and quality of excavator repair, through the use of modern information technology, on the basis of one-stop maintenance inspection, to form a complete service chain for the excavator repair industry. First, pay attention not to work under the large load that the machine can withstand, and use the machine within its capacity. As the manager of construction machinery, when designating the operator, they should hand over the random data and operation manual of the construction machinery to the operator so that they can master the mechanical performance and operating procedures normally, and should not arbitrarily deduct the relevant information. Second, we must try to increase and decrease the mechanical load evenly, so that the machine is in a relatively gentle load change. Specifically, we should increase and decrease the throttle more evenly to prevent the engine and working device from moving too much.

Third, scientific maintenance use lubricants in a timely manner.
A. More than half of the failures of excavating machinery are caused by poor lubrication. Due to the precision of each component of the construction machinery, good lubrication can maintain normal working gap and suitable working temperature (temperature), thereby reducing the degree of wear (a basic type of component failure) and reducing mechanical failure. . Normal and reasonable lubrication is one of the effective measures to reduce mechanical failure. For this reason, the first is to choose lubricants reasonably. In use, neither low-grade lubricants nor other types of lubricants can be used, and inferior products cannot be used. The second is to regularly check the quantity and quality of lubricants.
B. Various failures will inevitably occur during the use of excavating machinery. Among these faults, the impact of some faults on mechanical equipment may be very small, and some are more serious, and even cause major accidents such as machine damage. Experience has shown that serious mechanical failures are often caused by smaller failures. The reason lies in ignoring the timely treatment of minor faults. Therefore, mechanical faults, regardless of their size, should be eliminated in a timely manner, so as to maintain the normal performance of the machine and reduce the possibility of causing larger faults (Possibility).
Excavation machinery is a kind of high-input, high-yield machinery and equipment. People in the industry know that at this stage, they know that engineering is not good. If you want to make more money, you must try to reduce costs. Reducing costs involves all aspects of the excavation machinery. , Accessories, fuel consumption, etc. To be sure, we have more than 30 years of design and production experience in the professional production of various small excavating machinery products, which have created today ’s excavator brand. The current track 90 small excavator products use a unique kinetic hydraulic system The proportioning technology greatly reduces the user's use cost and is well received by users everywhere.
