裝載機(jī)液壓缸內(nèi)漏，油路進(jìn)了空氣，轉(zhuǎn)向系統(tǒng)壓力過(guò)低，導(dǎo)致泛起裝載機(jī)轉(zhuǎn)向沉重故障。管路連接錯(cuò)誤或者是管路有梗阻，都會(huì)導(dǎo)致裝載機(jī)轉(zhuǎn)向沉重故障現(xiàn)象。

裝載機(jī)先導(dǎo)壓力值的調(diào)整方法是先用專業(yè)的拆卸工具松開溢流閥鎖緊螺母，然后假如是先導(dǎo)壓力值偏小，就向順時(shí)針?lè)椒ㄕ{(diào)大先導(dǎo)壓力值，假如是壓力值偏小，就向逆時(shí)針?lè)椒ㄕ{(diào)小，調(diào)整先導(dǎo)壓力值后，裝載機(jī)轉(zhuǎn)向沉重故障排除。
Loader pilot pressure value adjustment method is to first use a professional removal tool loosen the locknut relief, and then if the pilot pressure value is too small, the pilot would turn up the pressure value in the clockwise method, if it is too small pressure on transfer of small counterclockwise method, adjusted pilot pressure value, loaders steering heavy troubleshooting.

停機(jī)熄火用壓力表檢查裝載機(jī)先導(dǎo)壓力值，正常的先導(dǎo)壓力值應(yīng)該是發(fā)念頭怠速的時(shí)候不低于2.2MPA,發(fā)念頭高速的時(shí)候要不高于5MPA,假如檢查裝載機(jī)壓力值不為劃定的值,那么導(dǎo)致裝載機(jī)轉(zhuǎn)向沉重故障現(xiàn)象泛起的原因就是先到壓力值分歧錯(cuò)誤，就要調(diào)整。
Stop stalling when the pilot pressure with a pressure gauge to check the value of the loader, the normal pilot pressure value should be no less than the engine idling 2.2MPA, or when the engine speed is higher than 5MPA, check if the value is not zoned pressure loaders given value, resulting in heavy steering loaders Symptom thrown reason is first pressure difference error, we must adjust.
