开掘机的无力及挖掘机的介绍

日期:2018-11-02   来源:/
面对一些开掘作业困难,作业地址较高时,一般开掘机现已无法胜任作业,这时候就会用到长臂开掘机,许多不良租借公司为了削减费用,私自把一般开掘机改装成长臂开掘机,这样在外观上来看虽然看不出什么,但是真的作业起来,非常简略呈现挖力不可的情况。下面长臂开掘机租借公司就为我们分析出了以下两点关于开掘机挖无力时应该怎么操作。
Faced with some difficulties in excavation operations and high working address, the general excavator is no longer competent. At this time, the long arm excavator will be used. In order to reduce the cost, many bad leasing companies have privately converted the general excavator into the long arm excavator, which can not be seen in appearance, but it really works. When it comes to industry, it is very simple to present the situation of digging hard. The following two points are analyzed for us by the Long Arm Excavator Rental Company about how to operate the excavator when the excavation force is not available.
开掘无力可分为两种情况:第一种为主张机不憋车,感觉负荷很轻;第二种为当动臂或斗杆伸终究时,主张机严峻憋车,甚至熄火。
There are two kinds of inability to excavate: the first one is that the tensioner does not hold up the car and feels the load is very light; the second one is that when the arm or bucket pole is extended eventually, it advocates that the machine should hold up severely or even stall.
第一种情况,即开掘无力,一同主张机憋车。和主张不机憋车比较,主张机憋车则标明油泵的吸收转矩大于主张机输出转矩,然后使得主张机超载。这种毛病应首要检查主张机速度传感体系是否正常,通过详尽的检查后,针对问题排除毛病,这样主张机速度传感体系就会康复正常功用了,憋车现象也就随之消失了。

The first situation is to dig up weakness, and to advocate the machine to suppress traffic. Comparing with the advocated non-locomotive traffic, the advocated locomotive traffic indicates that the absorption torque of the pump is greater than the output torque of the advocated engine, and then makes the advocated aircraft overload. This kind of defect should first check whether the machine speed sensing system is normal or not. After detailed inspection, the problem is eliminated. In this way, the machine speed sensing system will recover its normal function and the phenomenon of traffic jam will disappear.

 

第二种情况,开掘无力但主张机不憋车。开掘力的巨细取决于主泵输出压力,而主张机是否憋车是由油泵吸收转矩与主张机输出转矩间的联络抉择的。主张机不憋车,这就说明油泵吸收转矩较小,主张机负荷轻。假设此时开掘机的作业速度没有明显的反常,则应要点检查主泵的最大输出压力即体系溢流压力。假设溢流压力值低于规定值,则标明该安排液压回路的过载溢流阀设定值不正确,这时就需要翻滚调整螺丝来调整机器。

In the second case, we can not afford to hold back our cars. The magnitude of excavation force depends on the output pressure of the main pump. Whether the engine is holding up or not is decided by the connection between the torque absorbed by the oil pump and the output torque of the engine. It is argued that the machine does not hold down the vehicle, which means that the oil pump has a smaller absorption torque and a lighter load. Assuming that there is no obvious abnormal operation speed of the excavator at this time, the maximum output pressure of the main pump, i.e. overflow pressure of the system, should be checked. Assuming that the overflow pressure value is lower than the specified value, it indicates that the setting value of the overload overflow valve for the arrangement of hydraulic circuit is incorrect. At this time, it is necessary to roll the adjustment screw to adjust the machine.

长臂发掘机

一、什么样的发掘机可改装成加长臂发掘机
1. What kind of excavator can be refitted to add long arm excavator?
新机不主张改装,因为改装成加长臂发掘机今后,发掘机负荷增大,何况没过保修期容易与原厂发生售后服务的纠纷;五成新以下的机也不主张改装,因为机器运用年限比较旧,各方面功能减退,加上加长臂自身也有一定分量,很难发挥出加长臂发掘机应有的效率,最好的是5-8成新的发掘机改装成加长臂发掘机。
The new machine does not advocate refitting, because the load of the excavator will increase in the future, and it is easy to have disputes with the original factory after the warranty period; the machine under 50% of the new machine does not advocate refitting, because the service life of the machine is relatively old, the functions of all aspects are reduced, and the lengthened arm itself has a certain weight. It is difficult to give full play to the efficiency of the extended arm excavator. The best is that 5-80% of the new excavator is refitted into the extended arm excavator.
二、发掘机加长臂的运用范围
Two. Explore the application scope of machine plus long arm.
长臂发掘机有两段式发掘机加长臂和三段式发掘机加长臂,两段式发掘机加长臂首要适用于土石方根底和深堑发掘作业,河道清淤;三段式发掘机加长臂首要适用于高层建筑的拆开等工程。依据杠杆原理和力学原理,加长臂发掘机的受力比本来削减,应该尽量不要去重作业的场合施工。
Long arm excavator has two section excavator lengthening arms and three section excavator lengthening arms. Two section excavator lengthening arms are mainly suitable for earthwork and deep cutting excavation, River silt removal, and three section excavator lengthening arms are mainly suitable for high-rise building dismantling and other projects. According to leverage principle and mechanics principle, the force of the lengthened arm excavator is less than that of the original excavator, and the construction should be avoided as far as possible.
三、三段式发掘机加长臂怎么拆楼?
Three, three segment excavator and long arm how to demolish buildings?
首要仍是看高楼凹凸而定,举个比如,拆5层高楼:
The most important thing is to look at the bump of tall buildings. For example, 5 high-rise buildings should be demolished.
1.必须先运来一些泥或工业废物垫底,使发掘机升直冲击锤能够够得到楼顶。
1. Mud or industrial waste must be brought to the bottom so that the excavator can reach the roof with a vertical hammer.
2.待发掘机开上填充物后先使其安稳,而且留有满足的转向空间。
2. after the excavator is opened, the filler will be stabilized first, and there will be enough room for steering.
3.用冲击锤笔直墙面向里打墙(距顶1米左右),把墙翻开一个洞,碎料往里推,不要让它掉下来砸到自己。
3. Use the hammer to strike the wall in the direction of the straight wall (about 1 meter from the top), turn the wall over a hole, push the debris in, don't let it fall and hit itself.
4.把洞扩展,先不要动梁和柱子。把砖墙翻开后就打柱子,这样上面的梁支持不住也会往里面掉,确保自己的安全。按这样的次序从上到下,往里推动。
4. expand the hole before moving the beams and columns. When the brick wall is turned over, the pillars are struck, so that the beams on it can not support it and fall into it, so as to ensure their own safety. In this order, from top to bottom, push forward.
四、怎样挑选发掘机加长臂出产厂家
Four. How to choose excavators and long arm manufacturers
因为原装发掘机加长臂的价格太高,许多老板不能接受,所以副厂出产的发掘机加长臂成了大多数发掘机老板的首选,目前国内出产发掘机加长臂的厂家鱼龙混杂,有的小厂连工程师也没有,就几个焊工,所选用的材料也是廉价的不合格的钢材,其质量售后可想而知。
Because the price of the original excavator's elongated arm is too high to be accepted by many bosses, the elongated arm of the excavator produced by the deputy factory has become the first choice of most excavator owners. At present, the domestic manufacturers of the elongated arm of excavator are mixed with each other. Some small factories do not even have engineers. For a few welders, the materials chosen are also cheap. The quality of the unqualified steel can be imagined after sale.
