挖掘機全車無力動作慢的解決方法

很多時候會遇到的挖掘機全車無力、動作慢的問題，而很多時候同一個故障現(xiàn)象，卻可以有很多原因?qū)е碌?。那么下面我們就來講講挖掘機全車無力動作慢的解決方法是怎樣的。
Most of the time, we will encounter the problem of weakness and slow movement of the excavator, and in many cases, the same fault phenomenon can be caused by many reasons. So let's talk about how to solve the problem that the whole excavator is weak and slow.
我們要判斷一下發(fā)動機是否帶負荷。如果發(fā)動機感覺像空轉(zhuǎn)沒有出力的情況下直接可以排除掉發(fā)動機方面的因素。這個時候要確保挖掘機的先導一次壓力是否在標準數(shù)值。
We need to determine whether the engine is loaded. If the engine feels like idling without output can be directly eliminated engine factors. At this time to ensure that the first pressure of the excavator is in the standard value.
檢查每個動作輸出的主油壓力了。每款機子噸位的壓力不一樣的哈。詳細參照主機廠數(shù)據(jù)。測量的時候建議按照廠家的要求，大油門，強力模式，液壓油溫度，水溫都處于正常工作的標準溫度是很合適的。
Check the main oil pressure for each action output. Each machine tonnage pressure is not the same ha. Refer to OEM data for details. When measuring, it is recommended to follow the requirements of the manufacturer. Large throttle, strong force mode, hydraulic oil temperature and water temperature are all in the standard temperature of normal operation.
主壓力夠的情況下，也就是發(fā)動機轉(zhuǎn)速正常，我們就是考慮液壓系統(tǒng)的流量問題了。流量小，所以導致動作慢，顯得無力。但是壓力夠的話我們可以初步排除掉液壓系統(tǒng)主油路內(nèi)泄的問題。這個一般都是控制系統(tǒng)或者液壓泵變量機構(gòu)卡滯或者變量機構(gòu)內(nèi)泄導致的。
The main pressure is enough, that is, the engine speed is normal, we are considering the hydraulic system flow problem. Flow is small, so lead to slow action, appear weak. But if the pressure is enough, we can initially rule out the problem of leakage in the main oil circuit of the hydraulic system. This is generally the control system or hydraulic pump variable mechanism stuck or variable mechanism internal leakage.
如果反饋壓力正常，那就是泵的變量機構(gòu)有問題，這些都可以檢查的。不過這個檢查沒有工具也不好著手。我們要做的就是電磁閥輸出電壓是否正常？電磁閥有無卡滯？主泵電磁閥與其相關(guān)的電路有問題也會導致發(fā)動機憋車掉速冒黑煙等現(xiàn)象哈。
If the feedback pressure is normal, it is a problem with the variable mechanism of the pump, which can be checked. But it's hard to do without tools. What we need to do is whether the output voltage of the solenoid valve is normal? Is the solenoid valve stuck? The main pump solenoid valve and its related circuit problems will also lead to engine slow down black smoke and other phenomena.
濟南挖掘機租賃人員認為這個時候考慮的是液壓系統(tǒng)內(nèi)泄導致的動作慢，全車無力的現(xiàn)象。如果全車每個動作的壓力都不夠，我們要考慮的是共用的系統(tǒng)。比如主溢流閥，卸荷閥，液壓泵泵膽平面。當然每種液壓系統(tǒng)機型會有些區(qū)別的。
Ji 'nan excavator leasing personnel think that at this time, they consider the slow action caused by internal leakage of the hydraulic system, and the phenomenon of weakness of the whole car. If the pressure is not enough for every movement in the car, we need to consider the shared system. Such as the main relief valve, unloading valve, hydraulic pump bladder plane. Of course, each hydraulic system model will have some differences.
所以說雖然故障是一樣的，但原因卻不同，因此要具體問題，具體分析。如果您想知道更多問題的話，就來網(wǎng)站m.sybloom.com進行咨詢吧。
