省时 省力 省财富

很多时候，越是基本的东西，人们越是忽视和关注，认为这些基本的东西无关紧要。以下是挖掘机的一些基本知识。忽略这些基础知识可能无害，但了解这些基础知识可以让我们的工作更有成效。那么，人们能够了解哪些基本的小知识可以让他们的工作更有效率呢？

Many times, the more basic things are, the more people ignore and pay attention to them, and think that these basic things are irrelevant. Here are some basic knowledge of excavators. It may be harmless to ignore these basic knowledge, but understanding these basic knowledge can make our work more effective. So, what basic little knowledge can people learn to make their work more efficient?

一是对挖掘机前臂的认识；因为挖掘机的前臂是一个费力的杠杆，中间的销子是支点。因此，根据劳动密集型杠杆原理，动臂越长越省力。反而会比较费力，所以我们可以尽量让动臂在使用的时候达到更长的高度，这样挖掘机才能挖掘。强度越大，可以提高我们的工作效率。

First, the understanding of excavator forearm; Because the forearm of the excavator is a laborious lever, and the middle pin is the fulcrum. Therefore, according to the labor-intensive lever principle, the longer the boom, the less effort. Instead, it will be more laborious, so we can try to make the boom reach a longer height when in use, so that the excavator can dig. The greater the intensity, the more efficient we can be.

其次，挖掘机的回转等作业也是利用同样的原理来达到提高工作效率的目的。

Secondly, the rotary operation of excavator also uses the same principle to improve work efficiency.

三是铲斗，也是一种劳动密集型的杠杆原理。此外，当动臂较长时，挖掘机可以达到较大的尺寸。斗齿与地面的夹角，硬土更好在35度左右，一般土45度左右，因为这个角度可以很大限度地发挥压力。这时候挖掘距离很短，也减少了前臂伸展的长度。前臂越长，挖掘力越小。优点是：提高了挖掘机的工作效率，降低了油耗，减少了各销轴的摩擦和损耗，减少了挖掘机各部分的金属疲劳。

The third is the bucket, which is also a labor-intensive lever principle. In addition, when the boom is long, the excavator can reach a larger size. The angle between the bucket teeth and the ground should be about 35 ° for hard soil and about 45 ° for general soil, because this angle can exert pressure to a great extent. At this time, the excavation distance is very short, which also reduces the extension length of the forearm. The longer the forearm, the smaller the digging force. The advantages are: the working efficiency of the excavator is improved, the fuel consumption is reduced, the friction and loss of each pin shaft are reduced, and the metal fatigue of each part of the excavator is reduced.

长臂挖掘机租赁厂家提醒大家，在凹凸不平的地面上转向时，尽量将导向轮支撑在这一侧，但也不容易太高，要视地形而定。优点是：提高过弯速度。在不平路面上可以减少挖掘机导向轮侧面的受力，使导向轮的寿命更长。在不平路面上可以减少履带的侧向力，从而增加履带的使用寿命和压路机的使用寿命。

The leasing manufacturer of long arm excavator reminds everyone that when turning on uneven ground, try to support the guide wheel on this side, but it is not easy to be too high. It depends on the terrain. The advantages are: improve the bending speed. On the uneven road surface, the stress on the side of the guide wheel of the excavator can be reduced, so that the service life of the guide wheel is longer. The lateral force of the track can be reduced on uneven roads, thus increasing the service life of the track and the service life of the roller.

四是辅助元件，主要内容包括油箱、油管、散热器、滤清器和蓄能器。散热器的作用是将液压技术系统产生的热量散发到大气中，其常见问题包括漏油和散热不良。过滤器的作用是过滤混入液压油中的杂质，其常见故障有滤网堵塞。

The fourth is auxiliary components, mainly including oil tank, oil pipe, radiator, filter and accumulator. The function of the radiator is to dissipate the heat generated by the hydraulic technology system to the atmosphere. Its common problems include oil leakage and poor heat dissipation. The function of the filter is to filter the impurities mixed in the hydraulic oil. The common fault is that the filter screen is blocked.

蓄能器的作用是稳定发展控制油压并储存一定的能量以保证平稳运行，当发动机可能产生不同的故障而无法改善工作时，它可以将管理工作分析装置降到地上，其常见故障包括储能效果差，无法按顺序完成以上功能。辅助元件的故障现象一般比较明显，容易诊断。

The function of the accumulator is to stably control the oil pressure and store a certain amount of energy to ensure smooth operation. When the engine may produce different faults and cannot improve the work, it can lower the management work analysis device to the ground. Its common faults include poor energy storage effect and the inability to complete the above functions in sequence. The fault phenomenon of auxiliary components is generally obvious and easy to diagnose.
