一、高壓噴淋清洗機(jī)在啟動(dòng)后出現(xiàn)壓力不穩(wěn)定或時(shí)有時(shí)無(wú)。

1、 The pressure of high-pressure spray cleaning machine is unstable or sometimes not stable after starting.

（1）高壓水泵或進(jìn)水管路內(nèi)吸入了空氣，這時(shí)我們擰開水泵排氣閥，調(diào)低高壓清洗機(jī)工作壓力并運(yùn)轉(zhuǎn)一會(huì)，直到產(chǎn)生穩(wěn)定的壓力為止。

(1) When the air is sucked into the high-pressure water pump or the water inlet pipe, we turn on the exhaust valve of the water pump, lower the working pressure of the high-pressure cleaning machine and run it for a while until a stable pressure is generated.

（2）供水不足，這時(shí)要檢查水源的壓力是否足夠，有的高壓清洗機(jī)并不具備自吸功能，這時(shí)添置一個(gè)增壓泵即可問(wèn)題

(2) When the water supply is insufficient, check whether the pressure of the water source is enough. Some high-pressure cleaning machines do not have the self-priming function. At this time, the problem can be solved by adding a booster pump

（3）供水過(guò)濾器堵塞，這時(shí)只要清洗供水過(guò)濾器即可

(3) If the water supply filter is blocked, just clean the water supply filter

二、高壓清洗機(jī)達(dá)不到設(shè)備的額定壓力。

2、 The high pressure cleaning machine can not reach the rated pressure of the equipment.

（1）高壓清洗機(jī)運(yùn)轉(zhuǎn)時(shí)有一定的工作壓力達(dá)不到設(shè)備的額定壓力或者說(shuō)壓力只停留在一定范圍內(nèi)而不能上升,在這種情況下，應(yīng)先檢查高壓噴嘴的孔徑是否匹配，如不匹配更換高壓噴嘴即可。

(1) When the high-pressure cleaning machine is running, there is a certain working pressure that can not reach the rated pressure of the equipment, or the pressure only stays in a certain range and cannot rise. In this case, first check whether the aperture of the high-pressure nozzle matches, if not, replace the high-pressure nozzle.

（2）檢查調(diào)壓閥是否調(diào)到正確的位置。

(2) Check whether the pressure regulating valve is adjusted to the correct position.

（3）如果在排除這兩種情況下壓力仍然上不去，后檢查高壓泵內(nèi)密封組件（O型圈、水封）是否完好，活塞是否損壞。

(3) If the pressure still can't go up after eliminating these two conditions, finally check whether the sealing components (O-ring and water seal) in the high-pressure pump are in good condition and whether the piston is damaged.

三、高壓噴淋清洗設(shè)備在正常運(yùn)轉(zhuǎn)一定時(shí)間后壓力降低 。

3、 After a certain period of normal operation, the pressure of high pressure spray cleaning equipment decreases.

（1）檢查高壓噴嘴是否嚴(yán)重磨損，如磨損比較嚴(yán)重更換高壓噴嘴即可。小壓力設(shè)備的高壓噴嘴基本不會(huì)出現(xiàn)磨損現(xiàn)象，因?yàn)槲覀兯涓邏簢娮旎径歼M(jìn)行過(guò)熱處理的，但對(duì)于大壓力設(shè)備的高壓噴嘴就難以保證了

(1) Check whether the high pressure nozzle is seriously worn. If the wear is serious, replace the high pressure nozzle. The high-pressure nozzle of small pressure equipment will not wear, because the high-pressure nozzle we are equipped with is basically superheated, but it is difficult to guarantee the high-pressure nozzle of large pressure equipment

（2）檢查進(jìn)水過(guò)濾器是否堵塞，如進(jìn)水濾網(wǎng)堵塞了，將濾網(wǎng)取下用水清洗就可以了。如果是不清潔的水源造成過(guò)濾網(wǎng)經(jīng)常堵塞，可增大外置過(guò)濾器，或更換潔凈水源

(2) Check whether the inlet filter is blocked. If the inlet filter is blocked, remove the filter and clean it with water. If the filter screen is often blocked due to unclean water source, the external filter can be increased or the clean water source can be replaced

（3）分別檢查高壓噴淋清洗機(jī)的調(diào)壓閥、溢流閥和高壓水泵內(nèi)部的密封組件，如：調(diào)壓閥和溢流閥的O型圈是否磨損、彈簧與座面是否有磨損、泵內(nèi)部的O型圈是否磨損、水封是否有損壞、單向閥是否磨損或被異物墊起

(3) Respectively check the pressure regulating valve, overflow valve and sealing components inside the high-pressure water pump of the high-pressure spray cleaning machine, such as whether the O-ring of the pressure regulating valve and overflow valve is worn, whether the spring and seat surface are worn, whether the O-ring inside the pump is worn, whether the water seal is damaged, and whether the check valve is worn or padded by foreign matters
