CNC高壓清洗機用途廣泛，不僅適用於家庭、商業場所，更多（duō）會用於工業場合。但如果CNC高壓（yā）清洗（xǐ）機在長時間的使（shǐ）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（xiǎng）、漏油、開槍（qiāng）不出水等故障，那麽CNC高壓清洗機出現這（zhè）些故障怎麽維修？下麵來了解下（xià）。

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（jiào）聲

Abnormal squeal during operation

導致這一現象發生的主（zhǔ）要原因（yīn）是由於電機軸承缺油，這是91污需要及時在電（diàn）機的注油孔注入普通黃油，這種現（xiàn）象發生的不多，91污平時再給CNC高壓清洗機定期檢修（xiū）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（qīng）洗機壓力不穩（wěn）定

The pressure of CNC high-pressure washer is unstable

CNC高壓清洗機壓力不穩定主要（yào）是因為高壓水泵或進水管路內吸入了空（kōng）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（dǔ）塞，如果發現進水濾網堵塞（sāi），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（jiān）後（hòu）壓力降（jiàng）低

Pressure decreases after running for a period of time

CNC高壓清洗機在運行一段時間後壓力會有所降低，這種現象首先要（yào）檢查清洗機高壓噴嘴是否嚴重磨損（sǔn），普通壓力設備的高壓噴嘴基本上不會出（chū）現磨損（sǔn）現象，因為91污（men）所配的高（gāo）壓噴嘴都進行過熱處理。而非常高壓設備的高壓噴（pēn）嘴就難以保（bǎo）證了。其次需要分別檢查調壓閥和水泵（bèng）內部的（de）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（biàn）渾濁或乳白色

Crankcase lubricating oil becomes cloudy or milky white

CNC高壓清洗機在（zài）定期檢修維護時，通過視窗觀察，如果（guǒ）發現曲軸箱潤滑油變渾濁或乳白色時，說明高壓水泵內油（yóu）封密封不嚴或已（yǐ）經損壞，如不（bú）及時更換，水中的（de）雜質將嚴重損壞曲（qǔ）軸和連杆的使用壽命，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（yóu）是因（yīn）為泵內油封（fēng）損壞，這要求91污要及時更換，高壓水泵在運（yùn）轉時，曲軸和連杆在不停的（de）做往返（fǎn）式運（yùn）動，這時就要靠油給予潤（rùn）滑和降溫，所以高壓水泵不能缺（quē）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（gāo）壓水槍（qiāng）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（chéng）中，91污也許會發（fā）生調壓閥壓力正常而高壓水槍開槍不（bú）出水（shuǐ）或者高壓噴嘴噴射的水射流（liú）不規則、分散，這說明高壓噴嘴有（yǒu）異物堵塞，需（xū）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.
