Five tips to reduce the failure rate of excavator auger rigs, do you know

How to reduce the failure rate of drilling rig equipment? Various failures will inevitably occur in the use of auger rigs. If the causes of various failures can be correctly analyzed, effective and highly targeted preventive measures can be taken, and the damage speed of various parts of the machine can be slowed down as much as possible. It can effectively prevent mechanical failures, and the excavator auger should look for Zhizao Daguan. The following Zhizao Daguan shares five unique tricks to reduce the failure rate of auger equipment:

1. Ensure normal working load

Generally speaking, the wear of auger parts increases proportionally with the increase in load. When a part is subjected to a load higher than the average design load, its wear will increase. In addition, under other same conditions, stable load has less wear, less failure and lower life than dynamic load. Hydraulic motors that work under normal loads have a lower failure rate and longer life. On the contrary, the overloaded motor has a significantly increased probability of failure, and its lifespan will be shorter than the design index. The wear of the auger equipment that is often in a wide range of load changes is greater than that of the machinery that works continuously and stably. Ensuring a normal working load mainly depends on the operator's use of the auger.

2. Minimize the impact of harmful factors

(1) Reduce the influence of impurities

Impurities generally refer to non-metallic substances such as dust and soil, as well as some metal chips and wear products produced by the rotary drilling rig itself during use. Once these impurities enter the inside of the rotary digging and reach the mating surfaces, the harm is very great. Not only will the relative movement be blocked, the wear of the parts will be accelerated, but also the mating surfaces will be scratched, the lubricating oil film will be damaged, and the temperature of the parts will rise. , Deterioration of lubricating oil.

Therefore, for auger rigs working in harsh environments and complex conditions, firstly, use high-quality, matching parts and lubricating oils and greases to block the source of harmful impurities; secondly, do a good job in mechanical protection at the work site. , to ensure that the corresponding mechanism can work normally and prevent various impurities from entering the interior of the machine. For equipment that has failed, try to repair it at a regular repair place, and look for the wisdom of the excavator auger. During on-site repairs, protective measures should also be taken to prevent the parts replaced during on-site repairs from being polluted by dust and other impurities.

(2) Reduce the influence of temperature

In operation, the temperature of each component has its own normal range. For example, the temperature of the general cooling water is 80-90 °C, and the temperature of the hydraulic oil in the hydraulic transmission system is 30-60 °C. Below or above this range, the wear of the parts will be accelerated, the lubricant will be deteriorated, and the material properties will be changed.

For this reason, during the use of the auger, it is necessary to prevent overload operation at low temperature, ensure the normal operation of the low-speed preheating stage, and make the equipment reach the specified temperature before driving or working. Do not ignore it because there is no problem at that time. Important role; Second, to prevent the equipment from running at high temperatures, frequently check the values on various thermometers during operation, stop the machine immediately to check if there is a problem, and eliminate the fault in time. If the cause cannot be found at the moment, the equipment must not work without treatment. In the usual work, pay attention to check the working condition of the cooling system.

(3) Reduce various corrosive effects

The phenomenon that the metal surface is damaged by chemical or electrochemical action with the surrounding medium is called corrosion. This kind of corrosion will not only affect the normal operation of the external equipment of the rotary drilling rig, but also corrode the internal parts of the machine. For example, rainwater and chemical substances in the air enter the interior of the machine through the external channels and gaps of the mechanical parts, corrode the interior of the mechanical parts, accelerate the mechanical wear, and increase the mechanical failure.

3. Timely maintenance

For auger failures, no matter the size, they should be eliminated in time, so as to maintain the normal performance of the equipment and reduce the possibility of causing larger failures. In a sense, the timely processing of failures is an effective measure to reduce and prevent failures. The so-called timely treatment is to carry out regular maintenance and repair of the machinery in accordance with the maintenance procedures. Various maintenance and repairs must be carried out according to the requirements. The second is to strengthen the regular and irregular inspection of construction machinery in the process of use, to keep abreast of the operation of the machinery, and to deal with temporary faults in time. into a larger failure.

Fourth, ensure the reasonable lubrication of the machinery

The wear of the working surface of the parts, the corrosion of the surface of the parts and the aging of the materials are the three main replacement forms of mechanical parts under normal use conditions, and the failure caused by the wear of the working surface of the parts accounts for a large proportion. That is to say, the wear and tear of machinery is one of the main reasons for its various components to reach the extreme technical state. Then, to solve the wear problem of mechanical parts, in addition to using excellent materials, selecting advanced manufacturing processes, and designing reasonable mechanical structures, an important job to do in the process of use is to ensure reasonable lubrication of the machinery.

Five, take correct technical measures and organizational management measures

With the development of material science and design and manufacturing technology, many new technologies, new materials and new structures have been adopted in construction machinery, which requires more scientific and perfect technical support and management of equipment.

For this reason, as the organization management personnel and operators of construction machinery, one must pay attention to ensure that the machinery is prevented from damage, deformation, corrosion, etc. during the transportation and storage process. Second, it is necessary to strictly maintain the daily maintenance of the machinery, so that the machinery is in a good technical state. The third is to educate operators to correctly use and operate various construction machinery, reduce and prevent mechanical failures caused by human error, and look for the wisdom of the excavator auger. Fourth, the machinery must be carefully maintained, regular and irregular maintenance should be carried out correctly and reasonably, the machinery should be kept clean and clean, the technical status of the machinery should be checked regularly, abnormalities should be dealt with in a timely manner, and loose and misaligned parts should be tightened and adjusted in time. , preventive replacement of some wearing parts, etc.
