攪拌車行走無力或油溫過高怎么辦
混凝土自上料攪拌車行走無力或油溫過高怎么辦？這個(gè)問題是使用期間比較常見到的，要想做好預(yù)防就要知道原因，下面混凝土自上料攪拌車廠家為您解答。
What should we do if the concrete is unable to walk from the charging mixer or the oil temperature is too high? This problem is common during use. If you want to prevent it, you need to know the reason. The concrete mixer manufacturer will answer it for you.
混凝土自上料攪拌車行走無力或油溫過高時(shí)，就需要判別是離合器活塞密封不嚴(yán)仍是油壓缺乏引起的，但慣例檢測(cè)手段有時(shí)很難斷定是哪個(gè)原因引起毛病，尤其是在無動(dòng)力的情況下，檢查組裝好的變速器總成的各密封環(huán)就更困難了。此刻，可采用氣壓閥進(jìn)行測(cè)試。
When the concrete truck is unable to move or the oil temperature is too high, it is necessary to judge whether the clutch piston seal is not tight or the oil pressure is insufficient. However, it is sometimes difficult to determine the cause of the problem by conventional testing methods, especially when there is no power, it is more difficult to check the seal rings of the assembled transmission assembly. At this moment, the test can be carried out with a pneumatic valve.
1.將混凝土自上料攪拌車變速器控制閥拆掉（對(duì)組裝好的變速器應(yīng)在裝控制閥之前）；
1. Remove the concrete from the transmission control valve of the charging mixer (the assembled transmission shall be installed before the control valve);
2.順次給變速器各油孔通人0.6一0.8MPa的氣體，若某一個(gè)孔通人氣體時(shí)，聽到"嘭"的一聲且無漏氣聲或漏氣聲很小進(jìn)口計(jì)量泵，則闡明與之對(duì)應(yīng)的離合器活塞與缸筒間的密封杰出；
2. Fill each oil hole of the transmission with 0.6-0.8MPa gas in turn. If a hole is filled with gas, and a "bang" sound is heard, and there is no air leakage or the air leakage sound is very small, the inlet metering pump shall state that the sealing between the corresponding clutch piston and the cylinder barrel is excellent;
3.若聽不到活塞壓緊摩擦片的動(dòng)靜且漏氣聲較大，則闡明離合器活塞與缸筒間的密封失效，應(yīng)替換密封件。
3. If you can't hear the movement of the piston pressing the friction plate and the air leakage is loud, explain the failure of the seal between the clutch piston and the cylinder barrel, and replace the seal.
此外混凝土自上料攪拌車的液壓系統(tǒng)如果出現(xiàn)卸荷回路工作不良，當(dāng)攪拌車系統(tǒng)卸荷回路工作不良或沒有卸荷回路，是攪拌車系統(tǒng)不需要壓力時(shí)，而油液仍在溢流閥所調(diào)定的工作壓力下溢回油箱，或在卸荷壓力較高的情況下流回油路，此時(shí)應(yīng)認(rèn)真檢查系統(tǒng)卸荷回路的工作是否正常，如果卸荷油道被臟物堵塞，或電氣系統(tǒng)故障，引起卸荷作用的電磁閥不能工作，應(yīng)及時(shí)采取措施，予以排除。
In addition, if the unloading circuit of the hydraulic system of the concrete self feeding mixer truck does not work well, when the unloading circuit of the mixer truck system does not work well or there is no unloading circuit, the mixer truck system does not need pressure, and the oil still overflows back to the oil tank under the working pressure set by the overflow valve, or flows back to the oil circuit when the unloading pressure is high, then carefully check whether the system unloading circuit works normally, If the unloading oil passage is blocked by dirt or the electrical system fails, and the solenoid valve for unloading cannot work, measures shall be taken in time to eliminate it.
