        什么樣的挖掘機適合安裝伸縮臂?

        日期:2020-03-24   來源:http://www.qxngd.com/
          挖掘機的作用一定不能小到彌補太多的介紹,我們可以了解在日常生活和學習中,現在很多有特殊要求的挖掘機都會選擇安裝伸縮臂,那么什么樣的挖掘機適合安裝伸縮臂呢?如何解決挖掘機安裝后的偏差問題?詳細介紹了挖掘機的伸縮臂。
          The function of excavator must not be small enough to make up for too many introductions. We can understand that in our daily life and study, many excavators with special requirements will choose to install the telescopic boom, so what kind of excavator is suitable for installing the telescopic boom? How to solve the deviation problem after installing the excavator? The telescopic boom of the excavator is introduced in detail.
          一、什么樣的挖掘機可以用長臂挖掘機改裝
          1、 What kind of excavator can be refitted with a long arm excavator
          不建議對新機器進行改裝,因為改裝后挖掘機臂長,挖掘機負荷增加,且沒有保修期限,容易與原廠家售后服務產生糾紛;不建議改裝機器低于50%新的,因為這臺機器有一個舊的使用壽命,在所有方面的性能下降,和伸出臂本身有一定的重量,很難發揮延伸臂挖掘機由于效率,更好的是5 - 80%的新挖掘機改裝成伸出臂挖掘機。
          It is not recommended to refit the new machine, because after refitting, the arm of the excavator is long, the load of the excavator increases, and there is no warranty period, so it is easy to have disputes with the after-sales service of the original manufacturer; it is not recommended to refit the machine less than 50% new, because the machine has an old service life, the performance in all aspects decreases, and the extension arm itself has a certain weight, It's hard to play with reach excavators because of the efficiency, the best is that 5 - 80% of new excavators are converted into reach excavators.

          II. Scope of use of excavator extension arm
          挖掘機的伸縮臂由挖掘機的兩段伸縮臂和挖掘機的三段伸縮臂組成。三級挖掘機的伸縮臂主要用于高層建筑的拆除。根據杠桿和力學原理,加長臂挖掘機的受力比原來要小,應盡量不去繁重的工地施工。
          The telescopic arm of the excavator consists of two telescopic arms of the excavator and three telescopic arms of the excavator. The telescopic arm of the three-stage excavator is mainly used for the demolition of high-rise buildings. According to the principle of lever and mechanics, the force of the long arm excavator is smaller than the original one, so it should not go to the heavy construction site as much as possible.

          運行偏差故障:
          Operation deviation fault:
          摘要當有伸縮臂的挖掘機出現跑偏故障時,應首先檢查挖掘機的組合閥。取下限壓閥上的2根油管,用插頭堵住出油口,啟動發動機,用插頭組合閥拉動加長臂挖掘機移動控制手柄,檢測正常油壓;然后拆開另一側組合閥上的兩根油管,重新啟動發動機,觀察限壓閥上的兩個油孔是否有漏油流出,如果沒有漏油現象,則消除組合閥故障。這時,我們應該檢查一下旋轉接頭。
          When the excavator with telescopic arm has a deviation fault, the combination valve of the excavator should be checked first. Take 2 oil pipes on the lower limit pressure valve, plug the oil outlet, start the engine, pull the long arm excavator with the plug combination valve to move the control handle, and check the normal oil pressure; then dismantle the two oil pipes on the combination valve on the other side, restart the engine, and observe whether there is oil leakage from the two oil holes on the pressure limiting valve. If there is no oil leakage, eliminate the combination valve fault. At this point, we should check the central swivel.
          由于旋轉接頭的油路較多,油路容易串通,所以我們可以先拆下2根行走電機油管,再拆下1根電機油管。操作完畢后,重新啟動發動機,拉動油管馬達換向閥將其堵塞,觀察油壓是否過低,液壓馬達油孔是否有油流出。
          Since there are many oil circuits in the central rotary joint, the oil circuits are easy to be connected, so we can remove two oil pipes of the traveling motor first, and then one oil pipe of the motor. After the operation, restart the engine, pull the oil tube motor reversing valve to block it, and observe whether the oil pressure is too low and whether there is oil flowing out of the oil hole of the hydraulic motor.
