　　很多時(shí)候會(huì)遇到的挖掘機(jī)全車無(wú)力、動(dòng)作慢的問(wèn)題，而很多時(shí)候同一個(gè)故障現(xiàn)象，卻可以有很多原因?qū)е碌摹Ｄ敲聪旅嫖覀兙蛠?lái)講講挖掘機(jī)全車無(wú)力動(dòng)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(dòng)機(jī)是否帶負(fù)荷。如果發(fā)動(dòng)機(jī)感覺(jué)像空轉(zhuǎn)沒(méi)有出力的情況下直接可以排除掉發(fā)動(dòng)機(jī)方面的因素。這個(gè)時(shí)候要確保挖掘機(jī)的先導(dǎo)一次壓力是否在標(biāo)準(zhǔn)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(gè)動(dòng)作輸出的主油壓力了。每款機(jī)子噸位的壓力不一樣的哈。詳細(xì)參照主機(jī)廠數(shù)據(jù)。測(cè)量的時(shí)候建議按照廠家的要求，大油門，強(qiáng)力模式，液壓油溫度，水溫都處于正常工作的標(biāo)準(zhǔn)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(dòng)機(jī)轉(zhuǎn)速正常，我們就是考慮液壓系統(tǒng)的流量問(wèn)題了。流量小，所以導(dǎo)致動(dòng)作慢，顯得無(wú)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(wèn)題。這個(gè)一般都是控制系統(tǒng)或者液壓泵變量機(jī)構(gòu)卡滯或者變量機(jī)構(gòu)內(nèi)泄導(dǎo)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(jī)構(gòu)有問(wèn)題，這些都可以檢查的。不過(guò)這個(gè)檢查沒(méi)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(wú)卡滯？主泵電磁閥與其相關(guān)的電路有問(wèn)題也會(huì)導(dǎo)致發(fā)動(dòng)機(jī)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(jì)南挖掘機(jī)租賃人員認(rèn)為這個(gè)時(shí)候考慮的是液壓系統(tǒng)內(nèi)泄導(dǎo)致的動(dòng)作慢，全車無(wú)力的現(xiàn)象。如果全車每個(gè)動(dòng)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(dāng)然每種液壓系統(tǒng)機(jī)型會(huì)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(shuō)雖然故障是一樣的，但原因卻不同，因此要具體問(wèn)題，具體分析。如果您想知道更多問(wèn)題的話，就來(lái)網(wǎng)站m.loveindg.com進(jìn)行咨詢吧。

　　So although the fault is the same, but the reasons are different, so to specific problems, specific analysis. If you want to know more, please visit m.loveindg.com.
