冷再生機在壓實作業(yè)中驅動系統(tǒng)故障解決方法

來源：http://www.kqj188.com/ 日期：2023-09-20 發(fā)布人：

在排除電氣故障后，檢查振動馬達與振動軸的彈性聯(lián)軸器和振動軸內潤滑油的情況。潤滑油過多會使振頻上不去，一般是因馬達組合油封損壞向軸內漏油所致。如果冷再生租賃機振動軸花鍵套磨損嚴重，也會導致失振故障，此時應對補油壓力、系統(tǒng)工作壓力進行檢測，從而做出診斷。

After eliminating electrical faults, check the elastic coupling between the vibration motor and the vibration shaft, as well as the lubrication oil inside the vibration shaft. Excessive lubricating oil can prevent the vibration frequency from rising, usually due to damage to the motor combination oil seal and oil leakage into the shaft. If the vibration shaft spline sleeve of the cold regeneration leasing machine is severely worn, it can also lead to vibration failure. At this time, the oil replenishment pressure and system working pressure should be tested to make a diagnosis.

檢查油泵泄漏量、機械摩擦力大小、傳輸管道的泄漏和堵塞，調節(jié)閥的調定壓力和流量正確與否，查明后，應對癥排除。

Check the leakage rate of the oil pump, the size of mechanical friction force, the leakage and blockage of the transmission pipeline, and whether the set pressure and flow rate of the regulating valve are correct. After investigation, eliminate the symptoms.

另外，再檢查振動壓路機液壓馬達的容積效率，機械摩擦阻力和背壓力。

In addition, check the volumetric efficiency, mechanical friction resistance, and back pressure of the hydraulic motor of the vibratory roller again.

如果液壓馬達因磨損或密封件密封不良而泄漏量增加，或機械摩擦阻力過大，則多是液壓馬達轉速低、轉矩小的原因所在，應進而查明并對癥排除。

If the leakage rate of the hydraulic motor increases due to wear or poor sealing of the sealing components, or if the mechanical friction resistance is too high, it is mostly due to the low speed and low torque of the hydraulic motor, which should be further identified and eliminated accordingly.

由于冷再生租賃機機器的前后振動系統(tǒng)既獨立又相互聯(lián)系（共用補油泵），所以可應用“元件置換法”進行診斷。比如，有一輪振頻低時，可將前、后兩馬達的管路互換，若故障已轉移，則表明故障是在泵上，否則是馬達有故障。同樣，對用于變頻操作的排量控制閥也可采用同樣的“互換法”作診斷。

Due to the fact that the front and rear vibration systems of the cold regeneration leasing machine are both independent and interconnected (sharing a makeup oil pump), the "component replacement method" can be applied for diagnosis. For example, when there is a low vibration frequency in one round, the pipelines of the front and rear motors can be interchanged. If the fault has shifted, it indicates that the fault is on the pump, otherwise it is a motor fault. Similarly, the same "exchange method" can be used for diagnosis of displacement control valves used for variable frequency operation.

振動壓路機主油路的啟振初始壓力可達32MPa，其連續(xù)工作壓力大振輻時可達20MPa，小振幅時約為12MPa。當發(fā)動機在額定轉速下其連續(xù)工作壓力大大高于標準值時，則應檢查振動軸的轉動靈活性，即用專用工具旋轉振動軸，使偏心塊處在高位后再釋放，此時振動軸應能擺動幾次，若感覺阻力大，則應更換振動軸軸承。

The initial pressure of the main oil circuit of the vibration roller can reach 32MPa, and its continuous working pressure can reach 20MPa at high vibration amplitude and about 12MPa at small amplitude. When the continuous working pressure of the engine at rated speed is significantly higher than the standard value, the rotational flexibility of the vibration shaft should be checked. That is, use a special tool to rotate the vibration shaft, make the eccentric block at a high position, and then release it. At this time, the vibration shaft should be able to swing several times. If resistance is felt, the vibration shaft bearing should be replaced.
