如果雨刮器长时间发出异响，挡风玻璃就会模糊不清，影响驾驶员视力，对行车非常不利。今天我们就来了解一下搅拌机雨刮器异响的问题。

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.

雨刮器异响的原因一般来自四个方面：

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

1。雨刮器本身的问题导致雨刮器异响。雨刮片是橡胶制品，长时间使用后会老化或硬化，尤其是在冬天。如果此时无法清洗，请更换雨刮片。一般的雨刮器需要一两年更换一次。

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。雨刮器和风剥离力之间夹杂异物也会导致异响。搅拌机雨刮器打开时，有尖锐的摩擦声，可能是雨刮器下面有异物。好下车清洗一下。

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。刮水器连杆衬套的摩擦也会产生异响。随着搅拌机使用寿命的增加，雨刮连杆机构会老化，雨刮臂弹簧弹性下降，衬套磨损甚脱落。此时，必须检查刮水器臂或刮水器连杆衬套。

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。雨刮电机也有异响。如果雨刮器电机本身有异响，很可能是电机的使用寿命已经到了。好去维修站检查，以免影响司机的驾驶视线。

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.

使用雨刷器时，请注意以下几点：

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

1。定期检查雨刮片。如果雨刷器很脏或磨损严重，应及时清洗或更换，否则会影响其使用效果。用棉纱加酒精洗涤剂轻轻擦拭雨刮片上的污垢，但切记不要用汽油清洗，否则雨刮片可能会变形，影响其性能。

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。在检查自动混凝土搅拌机雨刮器工作情况时，先用水湿润挡风玻璃，否则会划伤玻璃。同时，由于雨刮片摩擦阻力大，可能损坏雨刮片或烧坏电机。打开刮水器后，注意电机是否有异响。如果电机有“嗡嗡”声，但没有转动，说明机械传动部分已经生锈或卡住，必须更换，立即关闭雨刮开关，以免烧坏电机。

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。在使用中关闭雨刮器开关时，雨刮片应回到挡风玻璃的下侧并停止。如果停止位置不正确，应进行调整。调整时可转动自动挡盖，顺时针转动可缩短挡位，逆时针转动可延长挡位。

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，如果自动混凝土搅拌机雨刮片结冰或被雪卡住，在使用雨刮器前必须冰雪，否则会损坏雨刮器或烧坏电机。

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.
