CNC高压清洗机用途广泛，不仅适用于家庭、商业场所，更多会用于工业场合。但如果CNC高压清洗机在长时间的使用以及缺乏定期的维护保养，会出现异常尖叫声、压力不稳定、异响、漏油、开枪不出水等故障，那么CNC高压清洗机出现这些故障怎么维修？下面来了解下。

CNC high-pressure cleaning machine has a wide range of applications, not only for families and commercial places, but also for industrial occasions. However, if the CNC high-pressure washer has been used for a long time and lacks regular maintenance, it will have abnormal squealing, unstable pressure, abnormal noise, oil leakage, and no water after firing. How to repair these faults of the CNC high-pressure washer? Let's take a look.

运行过程中出现异常尖叫声

Abnormal squeal during operation

导致这一现象发生的主要原因是由于电机轴承缺油，这是我们需要及时在电机的注油孔注入普通黄油，这种现象发生的不多，我们平时再给CNC高压清洗机定期检修维护时给予补充就可以了。

The main reason for this phenomenon is that the motor bearing is short of oil, which is that we need to inject ordinary butter into the oil injection hole of the motor in time. This phenomenon does not happen much. We usually supplement the CNC high-pressure washer during regular maintenance.

CNC高压清洗机压力不稳定

The pressure of CNC high-pressure washer is unstable

CNC高压清洗机压力不稳定主要是因为高压水泵或进水管路内吸入了空气所导致的，这时需要检查水源的压力是否足够，进水过滤器是否堵塞，如果发现进水滤网堵塞，将滤网取下用水清洗就可以了。

The unstable pressure of the CNC high-pressure cleaner is mainly caused by the suction of air in the high-pressure water pump or inlet pipe. At this time, it is necessary to check whether the pressure of the water source is sufficient and whether the inlet filter is blocked. If the inlet filter is blocked, remove the filter and clean it with water.

运行一段时间后压力降低

Pressure decreases after running for a period of time

CNC高压清洗机在运行一段时间后压力会有所降低，这种现象要检查清洗机高压喷嘴是否严重磨损，普通压力设备的高压喷嘴基本上不会出现磨损现象，因为我们所配的高压喷嘴都进行过热处理。而非常高压设备的高压喷嘴就难以保证了。其次需要分别检查调压阀和水泵内部的密封组件。

The pressure of the CNC high-pressure washer will decrease after a period of operation. First of all, check whether the high-pressure nozzle of the washer is seriously worn. The high-pressure nozzle of the ordinary pressure equipment will not wear, because the high-pressure nozzle we equipped is subject to overheating treatment. The high pressure nozzle of very high pressure equipment is difficult to guarantee. Secondly, it is necessary to check the sealing components inside the pressure regulating valve and water pump respectively.

曲轴箱润滑油变浑浊或乳白色

Crankcase lubricating oil becomes cloudy or milky white

CNC高压清洗机在定期检修维护时，通过视窗观察，如果发现曲轴箱润滑油变浑浊或乳白色时，说明高压水泵内油封密封不严或已经损坏，如不及时更换，水中的杂质将严重损坏曲轴和连杆的使用寿命，结果导致高压水泵损坏。

During the regular maintenance of the CNC high-pressure washer, through the window observation, if the crankcase lubricating oil becomes turbid or milky white, it indicates that the oil seal in the high-pressure water pump is not tight or has been damaged. If it is not replaced in time, the impurities in the water will seriously damage the service life of the crankshaft and connecting rod, resulting in the damage of the high-pressure water pump.

高压水泵底部漏油

Oil leakage at the bottom of high-pressure water pump

高压水泵底部漏油是因为泵内油封损坏，这要求我们要及时更换，高压水泵在运转时，曲轴和连杆在不停的做往返式运动，这时就要靠油给予润滑和降温，所以高压水泵不能缺润滑油。

The oil leakage at the bottom of the high-pressure water pump is due to the damage of the oil seal in the pump, which requires us to replace it in time. When the high-pressure water pump is running, the crankshaft and connecting rod are constantly moving back and forth. At this time, it is necessary to rely on oil for lubrication and cooling, so the high-pressure water pump cannot be short of lubricating oil.

调压阀压力正常而高压水枪开枪不出水

The pressure of the pressure regulating valve is normal, but the high-pressure water gun does not shoot water

在使用过程中，我们也许会发生调压阀压力正常而高压水枪开枪不出水或者高压喷嘴喷射的水射流不规则、分散，这说明高压喷嘴有异物堵塞，需要把高压喷嘴卸下进行清理。

In the process of use, we may have normal pressure of the pressure regulating valve and no water from the high-pressure water gun or irregular and scattered water jet from the high-pressure nozzle, which indicates that the high-pressure nozzle is blocked by foreign matters and needs to be removed for cleaning.
