如果雨刮器長時間發出異響，擋風玻璃就會模糊不清，影響駕駛員視力，對行車非常不利。今天我們就來了解一下攪拌機雨刮器異響的問題。

If the wiper makes abnormal noise for a long time, the windshield will be blurred, affecting the driver's vision, which is very detrimental to driving safety. Today, let's learn about the abnormal noise of the mixer wiper.

雨刮器異響的原因一般來自四個方面：

The causes of abnormal sound of wiper generally come from four aspects:

1。雨刮器本身的問題導致雨刮器異響。雨刮片是橡膠制品，長時間使用后會老化或硬化，尤其是在冬天。如果此時無法清洗，請更換雨刮片。一般的雨刮器需要一兩年更換一次。

1。 The problem with the wiper itself causes the wiper to make abnormal noise. Wiper blades are rubber products, which will age or harden after long-term use, especially in winter. If it cannot be cleaned at this time, replace the wiper blade. General wipers need to be replaced once a year or two.

2。雨刮器和風剝離力之間夾雜異物也會導致異響。攪拌機雨刮器打開時，有尖銳的摩擦聲，可能是雨刮器下面有異物。好下車清洗一下。

2。 Foreign matters mixed between the wiper and the wind stripping force will also cause abnormal noise. When the mixer wiper is opened, there is a sharp friction sound, which may be due to foreign matters under the wiper. OK, get out of the car and clean it.

3。刮水器連桿襯套的摩擦也會產生異響。隨著攪拌機使用壽命的增加，雨刮連桿機構會老化，雨刮臂彈簧彈性下降，襯套磨損甚脫落。此時，必須檢查刮水器臂或刮水器連桿襯套。

3。 The friction of wiper link bushing will also produce abnormal noise. As the service life of the mixer increases, the wiper linkage will age, the elasticity of the wiper arm spring will decrease, and the bushing will wear or even fall off. At this time, the wiper arm or wiper link bushing must be checked.

4。雨刮電機也有異響。如果雨刮器電機本身有異響，很可能是電機的使用壽命已經到了。好去維修站檢查，以免影響司機的駕駛視線。

4。 The wiper motor also makes abnormal noise. If the wiper motor makes abnormal noise, it is likely that the service life of the motor has expired. Go to the professional maintenance station for inspection, so as not to affect the driver's driving vision.

使用雨刷器時，請注意以下幾點：

When using the wiper, please pay attention to the following points:

1。定期檢查雨刮片。如果雨刷器很臟或磨損嚴重，應及時清洗或更換，否則會影響其使用效果。用棉紗加酒精洗滌劑輕輕擦拭雨刮片上的污垢，但切記不要用汽油清洗，否則雨刮片可能會變形，影響其性能。

1。 Check the wiper blades regularly. If the wiper is very dirty or severely worn, it should be cleaned or replaced in time, otherwise its use effect will be affected. Gently wipe the dirt on the wiper blade with cotton yarn and alcohol detergent, but remember not to clean it with gasoline, otherwise the wiper blade may deform and affect its performance.

2。在檢查自動混凝土攪拌機雨刮器工作情況時，先用水濕潤擋風玻璃，否則會劃傷玻璃。同時，由于雨刮片摩擦阻力大，可能損壞雨刮片或燒壞電機。打開刮水器后，注意電機是否有異響。如果電機有“嗡嗡”聲，但沒有轉動，說明機械傳動部分已經生銹或卡住，必須更換，立即關閉雨刮開關，以免燒壞電機。

2。 When checking the operation of the wiper of the automatic concrete mixer, wet the windshield with water first, otherwise the glass will be scratched. At the same time, the wiper blade may be damaged or the motor may be burnt out due to the large friction resistance of the wiper blade. After turning on the wiper, pay attention to whether the motor makes abnormal noise. If the motor has a "buzzing" sound but does not rotate, it means that the mechanical transmission part has been rusted or stuck and must be replaced. Turn off the wiper switch immediately to avoid burning the motor.

3。在使用中關閉雨刮器開關時，雨刮片應回到擋風玻璃的下側并停止。如果停止位置不正確，應進行調整。調整時可轉動自動擋蓋，順時針轉動可縮短擋位，逆時針轉動可延長擋位。

3。 When the wiper switch is turned off during use, the wiper blade shall return to the lower side of the windshield and stop. If the stop position is incorrect, adjust it. During adjustment, the automatic gear cover can be turned. Clockwise rotation can shorten the gear, and counterclockwise rotation can extend the gear.

4。在冬季，如果自動混凝土攪拌機雨刮片結冰或被雪卡住，在使用雨刮器前必須冰雪，否則會損壞雨刮器或燒壞電機。

4。 In winter, if the wiper blade of the automatic concrete mixer is frozen or stuck by snow, the snow and ice must be removed before using the wiper, otherwise the wiper will be damaged or the motor will be burned out.
