清潔設(shè)備的維修是和保養(yǎng)并進(jìn)的一項(xiàng)工作。很多機(jī)型質(zhì)保一年后會出現(xiàn)各種各樣的問題，有些是使用的問題，有些是設(shè)備配件老化的問題，當(dāng)然還有質(zhì)量不過關(guān)造成的故障。CNC高壓清洗機(jī)的故障有很多種，下面來講講CNC高壓清洗機(jī)壓力變小及異常啟動的原因。

The maintenance of cleaning equipment is a work that goes hand in hand with maintenance. Many models will have various problems after a year of warranty. Some are problems in use, some are problems with aging equipment accessories, and of course, there are problems caused by poor quality. There are many kinds of failures of the CNC high-pressure washer. The following is the reason why the pressure of the CNC high-pressure washer decreases and starts abnormally.

一、壓力變小的原因

1、 Reasons for the decrease of pressure

清洗機(jī)經(jīng)常會用一段時間后壓力變小的，如果您檢查機(jī)器沒有漏水現(xiàn)象，一般可以排除水封油封的問題。那就要先看下槍嘴了，因?yàn)殚L時間工作后的槍嘴會變大，就是水滴石穿的道理，槍嘴孔變大壓力自會減小。另外，如果過濾網(wǎng)太臟，水過不去也會導(dǎo)致壓力小，還有檢查槍有沒有堵塞的地方。這要一截截排查，看哪段有堵，疏通了就會好的。后要排查的是壓力閥和單向閽，壓力閥密封件磨損嚴(yán)重也會導(dǎo)致壓力小。

The pressure of the cleaning machine often decreases after a period of time. If you check that the machine has no water leakage, you can generally rule out the problem of water seal oil seal. It is necessary to take a look at the muzzle first, because the muzzle will become larger after a long time of work, which is the reason why water drops through stone, and the pressure will decrease when the muzzle hole becomes larger. In addition, if the filter screen is too dirty, the pressure will be low if the water cannot pass through, and there is also a place to check whether the gun is blocked. It needs to be checked to see which section is blocked, and it will be better if it is cleared. The pressure valve and one-way knob should be checked later. Severe wear of the pressure valve seal will also lead to low pressure.

二、設(shè)備不能正常啟動或啟動后幾秒后停機(jī)

2、 The equipment can not be started normally or shut down several seconds after starting

這種故障一般需要技術(shù)人員查驗(yàn)，排查方向按以下步驟進(jìn)行，因?yàn)橐鹦恫簧俨考?，所以還是要人員來定論。

This kind of fault generally needs to be checked by technicians, and the troubleshooting direction should follow the following steps. Since many parts need to be disassembled, professionals should still make a conclusion.

一步：先檢查進(jìn)水壓力，流量是否正常

Step 1: first check whether the water inlet pressure and flow are normal

二步：后檢查壓力開關(guān)工作是否正常，柱塞桿是否被卡住

Step 2: check whether the pressure switch works normally and whether the plunger rod is stuck

三步：查微動開關(guān)是否損壞或位置變動

Step 3: Check whether the microswitch is damaged or its position changes

四步：再檢查電路板

Step 4: Recheck the circuit board

五步：查繼電器

Step 5: Check the relay

六步：查電機(jī)工作狀態(tài)

Six steps: check the working state of the motor

一般要由售后才能解決的故障屬于比較大的故障，一般的小問題相信很多人可以自己動手解決，當(dāng)然也要注意多個事項(xiàng)多個細(xì)節(jié)才行，關(guān)注我們phdgoplaces.com，帶您了解更為多樣的事情。

Generally, faults that can only be solved by after-sales service are relatively large faults. I believe that many people can solve ordinary small problems themselves. Of course, we should pay attention to multiple issues and details. Follow us at phdgoplaces.com to help you understand more diverse things.
