高壓清洗機的清洗效果是建立在合理維護保養設備的前提上的，其中對高壓清洗機清洗效果影響較大的就是高壓噴嘴的狀態，以下幾個點尤為關鍵：

The cleaning effect of the high-pressure cleaning machine is based on the premise of reasonable maintenance of the equipment. The state of the high-pressure nozzle has a great influence on the cleaning effect of the high-pressure cleaning machine

1.正確的安裝。偏離軸心的墊圈，過度上緊或其它改變位置的問題均能產生不良影響；在安裝和清潔中，由于使用不正確的工具可能意外損壞高壓噴嘴。

1. Correct installation. Off axis gasket, over tightening or other position changing problems can have adverse effects; during installation and cleaning, the high pressure nozzle may be accidentally damaged due to the use of incorrect tools.

2.高壓清洗機在不同領域的清洗作業要對噴嘴合理選型。噴嘴的選型和材質等直接影響高壓清洗機的性能及清洗效果，每一種材質的噴嘴都有其合適的應用領域，噴嘴內部組件的微小改動便可產生極大的作用效果，沒有任何一種噴嘴能夠適合所有的應用場合。

2. The nozzle should be selected reasonably for the cleaning operation of high-pressure cleaning machine in different fields. The selection and material of nozzle directly affect the performance and cleaning effect of high-pressure cleaning machine. Each kind of nozzle has its suitable application field. The small change of internal components of nozzle can produce great effect. No nozzle can be suitable for all applications.

所以，噴嘴的孔徑、噴嘴結構設計、噴嘴加工精度和噴嘴材料都要與系統進行合理的匹配，這樣在達到清洗效果的同時，還會減少對設備的損傷。

Therefore, the nozzle aperture, nozzle structure design, nozzle processing accuracy and nozzle material should be reasonably matched with the system, so as to achieve the cleaning effect and reduce the damage to the equipment.

3.高壓噴嘴的應力疲憊磨損。眾所周知，噴嘴材料硬度是較高的，但當硬度高而韌性很低的時候，這種脆性材料受到氣力較大的雜質粒子的撞擊和沖擊的情況下，可能會發生材料斷裂磨損，形成噴嘴表面橫向或者徑向兩種類型的裂紋。堅硬噴嘴的脆性斷裂磨損。

3. Stress fatigue wear of high pressure nozzle. It is well known that the hardness of nozzle material is high, but when the hardness is high and the toughness is low, the brittle material may be subject to the impact and impact of the impurity particles with large air force, and the material may fracture and wear, forming two types of cracks on the nozzle surface, transverse or radial. Brittle fracture and wear of hard nozzle.

盡量減少這種磨損，就是要特別留意清洗介質的純凈性，盡量不要含有雜質，盡量降低對它的磨損機率和程度。

To minimize this kind of wear is to pay special attention to the purity of the cleaning medium, try not to contain impurities, and try to reduce its wear probability and degree.

4.意外損害對噴嘴的危害。為了安全起見，盡管高壓噴嘴口通常都設計成凹式，但我們如果不正確的使用和不能及時進行保養和維護，扇形噴嘴的偏移結構是很容易遭受到損害的。

4. Accidental damage to the nozzle. For the sake of safety, although the high-pressure nozzle is usually designed to be concave, if we do not use it correctly and do not maintain it in time, the offset structure of the fan nozzle will be easily damaged.

使用高壓清洗機時要留意保護好噴嘴，減少磨損，延長它的壽命，就可以減少更換頻率，可以降低高壓清洗機的使用成本。高壓清洗機在長期的運轉工作過程中，必然會對各個零部件產生一定的磨損，但是，我們也可以通過采取一些預防措施，盡量減少這些磨損，延長高壓清洗設備各個零部件的使用壽命。

When using the high-pressure cleaning machine, pay attention to protect the nozzle, reduce wear and prolong its service life, which can reduce the replacement frequency and reduce the use cost of the high-pressure cleaning machine. High pressure cleaning machine in the long-term operation process, will inevitably produce certain wear on various parts, but we can also take some preventive measures to minimize these wear and prolong the service life of various parts of high pressure cleaning equipment.
