一：大型混凝土攪拌機供油量不足導致輸出轉(zhuǎn)速和輸出轉(zhuǎn)矩低

1： The insufficient oil supply of large concrete mixer leads to low output speed and torque

解決辦法：供油液壓泵吸油口過濾器堵塞，此時可清洗濾油器；油液鉆度過大，此時可更換適合的油液；軸向或徑向間隙過大等原因等造成，此時要研磨定子或其他有關零件，使軸向間隙符合要求。

Solution: if the filter at the oil suction port of the oil supply hydraulic pump is blocked, the oil filter can be cleaned; if the oil drill is too large, the suitable oil can be replaced; if the axial or radial clearance is too large, the stator or other relevant parts should be ground to make the axial clearance meet the requirements.

二：大型混凝土攪拌機液壓馬達的原動機功率或轉(zhuǎn)速不當導致輸出轉(zhuǎn)速和輸出轉(zhuǎn)矩低

2： The output speed and torque of hydraulic motor of large-scale concrete mixer is low due to improper power or speed of prime mover

解決辦法：原動機功率不匹配，此時需要更換原動機，使之與液壓泵功率匹配；原動機轉(zhuǎn)速低于額定轉(zhuǎn)速，此時可選用轉(zhuǎn)速滿足要求的原動機。

Solution: if the prime mover power does not match, the prime mover needs to be replaced to match the power of the hydraulic pump; if the prime mover speed is lower than the rated speed, the prime mover with the rotational speed meeting the requirements can be selected.

三：大型混凝土攪拌機各連接處密封不嚴，有空氣混入

3： The joints of large-scale concrete mixer are not tightly sealed and air is mixed in

解決辦法：檢查和緊固各連接處，提高密封性能。

Solution: check and tighten the joints to improve the sealing performance.

四：工作介質(zhì)污染，液壓馬達內(nèi)部通道被堵塞

4： The working medium is polluted and the internal channel of hydraulic motor is blocked

解決辦法：拆解，仔細清洗并更換清潔的工作介質(zhì)。

Solution: disassemble, carefully clean and replace clean working medium.

五：大型混凝土攪拌機配流盤和葉片磨損，內(nèi)泄漏大

5： The valve plate and blade of large concrete mixer are worn and the internal leakage is large

解決辦法：修復或更換有關零件。

Solution: repair or replace the relevant parts.

六：大型混凝土攪拌機液壓系統(tǒng)中單向閥密封不良

6： Poor sealing of check valve in hydraulic system of large concrete mixer

解決辦法：修理單向閥閥座或更換有關零件，使閥座與鋼球嚴格密合。

Solution: repair the check valve seat or replace the relevant parts, so that the valve seat and steel ball are tightly closed.

七：液壓系統(tǒng)中溢流閥失靈

7： Overflow valve failure in hydraulic system

解決辦法：修理或更換溢流閥。

Solution: repair or replace the relief valve.相信看了本文的全自動混凝土攪拌車
