With the continuous development of science and technology, the continuous improvement of living standards, industrial technology is also constantly promoted, the use of vibratory roller is more and more widely. However, it is inevitable that the vibratory roller will have faults in the process of use, and non vibration is one of the problems. The following summarizes the relevant knowledge points, and then look down:

造成振動壓路機(jī)振動輪不振動的主要原因包括：

The main reasons for non vibration of vibratory roller include:

（1）控制電路故障

(1) Control circuit fault

控制閥的電源電路處于斷路狀態(tài)或者控制線圈損壞，都會造成閥芯不能換向而不能與液壓油腔接頭而驅(qū)動馬達(dá)產(chǎn)生激振。

If the power supply circuit of the control valve is in the open circuit state or the control coil is damaged, the valve core will not be able to change direction and cannot connect with the hydraulic oil chamber, and the motor will be excited.

（2）換向閥故障

(2) Directional valve failure

當(dāng)液壓油受到污染，其中的雜質(zhì)進(jìn)入到滑閥的關(guān)閉位置而造成電磁閥不能驅(qū)動時，也會造成液壓馬達(dá)不能將油路接通，造成壓路機(jī)不能產(chǎn)生振動。

When the hydraulic oil is polluted and the impurities enter into the closed position of the slide valve, the solenoid valve can not be driven, the hydraulic motor can not connect the oil circuit, and the roller can not produce vibration.

振動壓路機(jī)不振動的解決辦法：

The solution of vibration roller not vibrating:

應(yīng)該檢查電路，檢查過程中使用一根導(dǎo)線，將其中一端與電源連接，另一端則與電磁閥驅(qū)動線圈的火線端相連，若電磁閥振動則表明是電源電路故障，則應(yīng)該對電路進(jìn)行檢查，查出故障后予以處理。

First of all, the circuit should be checked. In the process of checking, a wire should be used to connect one end with the power supply, and the other end with the live wire end of the solenoid valve drive coil. If the solenoid valve vibrates, it indicates that the power supply circuit is faulty, then the circuit should be checked, and the fault should be handled after finding out.

若連接之后依然不能振動，則應(yīng)該將電磁閥拆下，并手動推動閥芯，振動輪振動后，表明時電磁控制線圈損壞；也可使用導(dǎo)線與電磁閥火線的接線柱刮火，若沒有火花，則表明電磁線圈斷開。若出現(xiàn)火花則說明電磁線圈正常工作，但依然不能振動，則表明滑閥被卡死，需要對閥體進(jìn)行檢查。

If it still can't vibrate after connecting, the solenoid valve should be removed and the valve core should be pushed manually. After the vibration of the vibrating wheel, it indicates that the electromagnetic control coil is damaged; You can also use the terminal of the wire and the live wire of the solenoid valve to blow the fire. If there is no spark, it indicates that the solenoid coil is disconnected. If there is a spark, it means that the electromagnetic coil is working normally, but it still can't vibrate, it means that the slide valve is stuck and the valve body needs to be checked.

總之，如果出現(xiàn)壓路機(jī)振動系統(tǒng)振動輪不振動故障時，按照以上方法檢驗(yàn)，定能找到原因，及時解決故障，以免延誤工期，造成損失。

In short, if the vibration wheel of the roller vibration system does not vibrate, according to the above methods, we can find the reason and solve the fault in time, so as to avoid delay of construction period and loss.
