挖掘机拆楼臂安装前需要注意哪些细节?

日期:2018-12-06   来源:http://www.dyqicheng.com/
今天几个客人来到我公司跟我讲还是我公司做的拆楼臂质量可靠,用了快一个月了也没出什么质量问题,反到是其他厂家给他们做了几套拆楼臂,经常有这样那样的问题,突出的就是铲斗油缸拉缸,用了不到一个月就一台机已经用坏了2条铲斗油缸,问我们用的是什么品牌的油缸,质量这么好。
  Today, several guests came to my company to tell me that the quality of our company's demolition arm is reliable. It has been used for almost a month without any quality problems. On the contrary, other manufacturers have made several sets of demolition arm for them. There are often such and such problems. The most prominent one is the bucket cylinder pulling cylinder. It takes less than a month to build a machine. Two bucket cylinders have been damaged. Ask us what brand of cylinders we use. The quality is so good.
  并想了解一下我公司现成的油缸是否能装到他们那几台拆楼臂挖机上面去,我叫客人让那个厂家把铲斗油缸图纸发过来,结果发现不通用,油缸行程我公司比那家的长60mm,安装的销子孔是一样的,如果装上我公司的铲斗油缸会出现收的时候收不到位,伸的时候锤子会碰到小臂,所以用不了。出现这种拉缸的问题很明显是油缸质量问题,听说那油缸是肇庆那边买的,具体厂家不祥。我公司是用专业的油缸,。所以质量相对可靠一些。
  And I want to know if our existing cylinders can be installed on their several arm diggers for demolition. I asked the customer to ask the manufacturer to send the drawings of bucket cylinders. It was found that they are not universal. Our cylinder stroke is 60 mm longer than that one. The pin holes installed are the same. If we install our bucket cylinders, it will be the same. The hammer will touch the arm when it stretches, so it will not be used. The problem of this kind of cylinder pulling is obviously the quality problem of the cylinder. I heard that the cylinder was bought over there in Zhaoqing. The specific manufacturer is ominous. Our company is a cylinder company which belongs to Sanyi ZTE and Hunan Sanxing. So the quality is relatively reliable.
  这客人一共订了7套拆楼臂,原本全放我公司做的,但要求4月25日前要交完货,当时谈的时已到3月初,离交货时间只有50天左右,3月、4月又是我公司忙的时候,所以我们只接了4套,让了3套给其他厂家,那几套拆臂我去看过,跟我公司的挖机拆楼臂相比还是有不少差距的,从以下几点比较:
  The customer ordered seven sets of dismantling arms, which were originally made by our company, but required delivery before April 25. At that time, the time of delivery was only about 50 days, and March and April were our busiest time. So we only received four sets and let three sets to other manufacturers. I have seen those sets of dismantling arms. Compared with our company's excavator demolition arm, there are still many gaps, from the following points:
  一、从加装的备用阀比较,我公司用的是合资备用阀,脚踩阀也是CAT原装的,那个厂家用的是国产备用阀和国产脚踩阀,这里一台机成本相差大几千块,从美观方面比较合资备用阀装好后很美观、整洁。国产备用阀管路显的很乱,非常不美观。从操作方面比较:CAT原装脚踩阀踩的时候脚感很好,国产脚踩阀踩的时候非常僵硬。从常远比较:合资备用阀很少会出现漏油的情况,国产备用阀出现漏油的情况概率会大一些。
  1. Comparing the spare valves installed, our company uses the joint-venture spare valves, and the foot-stepping valves are also the original ones of CAT. The manufacturer uses the domestic spare valves and the domestic foot-stepping valves. The cost of a machine here varies greatly by several thousand yuan, which makes the joint-venture spare valves beautiful and neat after being installed. The domestic spare valve pipeline is very messy and beautiful. Comparing from the operation: The foot feels very good when the original CAT foot stepping on the valve, while the domestic foot stepping on the valve is very stiff. From long-term comparison: Joint-venture spare valves rarely leak, and domestic spare valves have a higher probability of leaking.

  二、从臂的用材上比较,我听客人说他们上下盖板是用Q550的材料,我公司用的是Q690D材料,这里一套臂我们直接材料成本又比他们高几千块,当然我公司的拆楼臂强度自然会他们的好很多。
  2. Comparing the materials used in the arms, I heard that the upper and lower cover plates are made of Q550 material. Our company uses Q690D material. The direct material cost of a set of arms here is several thousand yuan higher than theirs. Of course, the strength of the arm of our company will naturally be much better than theirs.
  三、从软管的用材比较,我公司用的是美国GATES的油管,那个厂家用的油管品牌不清楚,但看一去质量一般般,一套臂下来成本我公司又比那家公司高两叁仟元。
  3. From the comparison of hose materials, our company uses GATES tubing. The brand of tubing used by that manufacturer is not clear, but look at the general quality, the cost of a set of arms is two or three thousand yuan higher than that company.
  四、从铲斗油缸来比较,我公司用的三一中兴的油缸,那家公司用的是一般厂家生产的油缸,这样一条油缸我公司又比那家公司贵仟块。
  4. Comparing with the bucket cylinder, the Sany ZTE cylinder used by our company is the cylinder manufactured by the general manufacturer. This kind of cylinder is more expensive in our company than in that company.
  这样算下来,他们一套臂比我少壹万多元的成本。所以说在谈挖掘机拆楼臂的时候一定要让厂家提祥细的产品图纸,和注明相关外购配件的品牌、型号、原产地等相关信息。只有相关技术要求统一后才好比价格,不然一套22米的挖掘机三节拆楼臂相关万儿八千真的不多。
  In this way, they have a set of arms less than 10,000 yuan in cost than I do. So when talking about the excavator's dismantling arm, we must let the manufacturer mention the detailed product drawings, and indicate the brand, model, origin and other relevant information of the relevant outsourced accessories. Only when the relevant technical requirements are unified can it be compared to the price. Otherwise, a set of 22-meter excavator with three dismantling arms is not much.
