CNC高壓清洗機用途廣泛，不僅適用于家庭、商業場所，更多會用于工業場合。但如果CNC高壓清洗機在長時間的使用以及缺乏定期的維護保養，會出現異常尖叫聲、壓力不穩定、異響、漏油、開槍不出水等故障，那么CNC高壓清洗機出現這些故障怎么維修？下面來了解下。

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.

運行過程中出現異常尖叫聲

Abnormal squeal during operation

導致這一現象發生的主要原因是由于電機軸承缺油，這是我們需要及時在電機的注油孔注入普通黃油，這種現象發生的不多，我們平時再給CNC高壓清洗機定期檢修維護時給予補充就可以了。

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高壓清洗機壓力不穩定

The pressure of CNC high-pressure washer is unstable

CNC高壓清洗機壓力不穩定主要是因為高壓水泵或進水管路內吸入了空氣所導致的，這時需要檢查水源的壓力是否足夠，進水過濾器是否堵塞，如果發現進水濾網堵塞，將濾網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.

運行一段時間后壓力降低

Pressure decreases after running for a period of time

CNC高壓清洗機在運行一段時間后壓力會有所降低，這種現象首先要檢查清洗機高壓噴嘴是否嚴重磨損，普通壓力設備的高壓噴嘴基本上不會出現磨損現象，因為我們所配的高壓噴嘴都進行過熱處理。而非常高壓設備的高壓噴嘴就難以保證了。其次需要分別檢查調壓閥和水泵內部的密封組件。

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.

曲軸箱潤滑油變渾濁或乳白色

Crankcase lubricating oil becomes cloudy or milky white

CNC高壓清洗機在定期檢修維護時，通過視窗觀察，如果發現曲軸箱潤滑油變渾濁或乳白色時，說明高壓水泵內油封密封不嚴或已經損壞，如不及時更換，水中的雜質將嚴重損壞曲軸和連桿的使用壽命，結果導致高壓水泵損壞。

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.

高壓水泵底部漏油

Oil leakage at the bottom of high-pressure water pump

高壓水泵底部漏油是因為泵內油封損壞，這要求我們要及時更換，高壓水泵在運轉時，曲軸和連桿在不停的做往返式運動，這時就要靠油給予潤滑和降溫，所以高壓水泵不能缺潤滑油。

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.

調壓閥壓力正常而高壓水槍開槍不出水

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

在使用過程中，我們也許會發生調壓閥壓力正常而高壓水槍開槍不出水或者高壓噴嘴噴射的水射流不規則、分散，這說明高壓噴嘴有異物堵塞，需要把高壓噴嘴卸下進行清理。

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.
