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(jī)械摩擦力大小、傳輸管道的泄漏和堵塞，調(diào)節(jié)閥的調(diào)定壓力和流量正確與否，查明后，應(yīng)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(jī)液壓馬達(dá)的容積效率，機(jī)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(dá)因磨損或密封件密封不良而泄漏量增加，或機(jī)械摩擦阻力過大，則多是液壓馬達(dá)轉(zhuǎn)速低、轉(zhuǎn)矩小的原因所在，應(yīng)進(jìn)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(jī)機(jī)器的前后振動系統(tǒng)既獨(dú)立又相互聯(lián)系（共用補(bǔ)油泵），所以可應(yīng)用“元件置換法”進(jìn)行診斷。比如，有一輪振頻低時，可將前、后兩馬達(dá)的管路互換，若故障已轉(zhuǎn)移，則表明故障是在泵上，否則是馬達(dá)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(jī)主油路的啟振初始壓力可達(dá)32MPa，其連續(xù)工作壓力大振輻時可達(dá)20MPa，小振幅時約為12MPa。當(dāng)發(fā)動機(jī)在額定轉(zhuǎn)速下其連續(xù)工作壓力大大高于標(biāo)準(zhǔn)值時，則應(yīng)檢查振動軸的轉(zhuǎn)動靈活性，即用專用工具旋轉(zhuǎn)振動軸，使偏心塊處在高位后再釋放，此時振動軸應(yīng)能擺動幾次，若感覺阻力大，則應(yīng)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.
