自動上料攪拌車的裝料卸料主要是靠液壓系統(tǒng)來實現(xiàn)的，液壓系統(tǒng)一旦出故障，整個攪拌車都不能正常工作了。下面來講講攪拌車液壓系統(tǒng)出問題的六個表現(xiàn)以及有什么辦法。

The loading and unloading of the automatic feeding mixer is mainly realized by the hydraulic system. Once the hydraulic system fails, the entire mixer cannot work normally. Now let's talk about the six symptoms of problems in the hydraulic system of the mixer and the solutions.

1.攪拌罐不能轉(zhuǎn)動：

1. The mixing tank cannot rotate:

a.無補液壓油：檢查補油泵及油箱；b.補油壓力過低：檢查油壓，將補油壓力調(diào)14-18兆帕；c.檢查油箱油位是否滿足液壓系統(tǒng)工作：油位不足需及時補充同企業(yè)同型號的油液；d.連接盤花鍵套內(nèi)花鍵損壞：更換連接盤或主泵通軸；e.吸油管路斷裂、被擠壓：更換或修理吸油管路；f.排量控制線脫開：連接好排量控制線；g伺服閥、銷損壞：更換伺服閥、銷；h.控制油路被異物堵塞：清洗油路；i.濾油器太臟：清洗或更換濾油器。

a. No hydraulic oil replenishing: check the oil replenishing pump and oil tank; b. Too low make-up pressure: check the oil pressure and adjust the make-up pressure to 14-18 MPa; c. Check whether the oil level in the oil tank meets the requirements of the hydraulic system: if the oil level is insufficient, the oil of the same brand and model shall be replenished in time; d. The spline inside the connecting disc spline sleeve is damaged: replace the connecting disc or the main pump shaft; e. Broken or squeezed oil suction pipeline: replace or repair the oil suction pipeline; f. Discharge control line is disconnected: connect the discharge control line; G Damaged servo valve and safety pin: replace the servo valve and safety pin; h. The control oil circuit is blocked by foreign matters: clean the oil circuit; i. The oil filter is too dirty: clean or replace the oil filter.

2.攪拌罐啟動慢：

2. Slow startup of mixing tank:

a.濾芯損壞或太臟：清洗或更換濾芯；b.油路連接松動或密封件損壞：擰緊或更換密封；c.油箱油位不足，及時補足油量；e.控制軟軸損壞：更換軟軸。

a. Damaged or dirty filter element: clean or replace the filter element; b. Loose oil circuit connection or damaged seal: tighten or replace the seal; c. If the oil level in the oil tank is insufficient, replenish the oil in time; e. Damaged control flexible shaft: replace the flexible shaft.

3.工作時有噪音：

3. Noise during operation:

a.吸油路漏氣：擰緊或更換密封件；b.油的標(biāo)號不配：更換合適的標(biāo)號液壓油；c.泵與馬達、萬向軸等的連接松動：緊固連接螺栓；d.油箱油量過少：給油箱補油。

a. Air leakage of oil suction circuit: tighten or replace the seal; b. Improper oil grade: replace the hydraulic oil with proper grade; c. Loose connection between pump and motor, cardan shaft, etc.: tighten the connecting bolts; d. Too little oil in the oil tank: refill the oil tank.

4.油溫過高：

4. The oil temperature is too high:

a.液壓油標(biāo)號不對：更換合適標(biāo)號的液壓油；b.液壓油臟活液壓系統(tǒng)超負荷工作：更換液壓油或調(diào)整負荷；c.冷卻風(fēng)扇不轉(zhuǎn)，油溫器損壞：更換油溫器；d.冷卻器過油量不夠：及時補油；e.液壓件內(nèi)泄嚴(yán)重：更換有關(guān)零部件；f.濾油器臟活損壞：清洗或更換濾油器。

a. Incorrect hydraulic oil grade: replace the hydraulic oil with proper grade; b. The hydraulic oil is dirty and the hydraulic system is overloaded: replace the hydraulic oil or adjust the load; c. The cooling fan does not rotate and the oil temperature sensor is damaged: replace the oil temperature sensor; d. Insufficient oil passing through the cooler: replenish oil in time; e. Serious internal leakage of hydraulic parts: replace relevant parts; f. The oil filter is dirty and damaged: clean or replace the oil filter.

5.攪拌罐轉(zhuǎn)速不快（工作無力）：

5. The speed of the mixing tank is not fast (unable to work):

a.輔助泵溢流壓力過低：調(diào)整溢流壓力；b.輔助泵損壞：更換輔助泵。

a. The overflow pressure of the auxiliary pump is too low: adjust the overflow pressure; b. Damaged auxiliary pump: replace the auxiliary pump.

6.軸封漏油：

6. Oil leakage of shaft seal:

a.油封老化：更換新油封；b.花鍵連接盤軸向未定，其端面與油封摩擦：更換連接盤。

a. Oil seal aging: replace it with a new one; b. The axial direction of the splined connecting disc is uncertain, and its end face rubs against the oil seal: replace the connecting disc.

掌握了攪拌車液壓系統(tǒng)的故障處理辦法，就不用怕液壓系統(tǒng)出故障了，當(dāng)然，如果好好保養(yǎng)攪拌車的液壓系統(tǒng)，就可以大大減少攪拌車的故障。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.fxsgujg.cn了解吧！

If you have mastered the troubleshooting method of the hydraulic system of the mixer, you will not be afraid of the hydraulic system failure. Of course, if you properly maintain the hydraulic system of the mixer, you can greatly reduce the failure of the mixer. More relevant content will come to our website http://www.fxsgujg.cn Understand!
