高压清洗机的清洗效果是建立在合理维护保养设备的前提上的，其中对高压清洗机清洗效果影响较大的就是高压喷嘴的状态，以下几个点尤为关键：

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.正确的安装。偏离轴心的垫圈，过度上紧或其它改变位置的问题均能产生不良影响；在安装和清洁中，由于使用不正确的工具可能意外损坏高压喷嘴。

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.高压清洗机在不同领域的清洗作业要对喷嘴合理选型。喷嘴的选型和材质等直接影响高压清洗机的性能及清洗效果，每一种材质的喷嘴都有其合适的应用领域，喷嘴内部组件的微小改动便可产生极大的作用效果，没有任何一种喷嘴能够适合所有的应用场合。

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，喷嘴的孔径、喷嘴结构设计、喷嘴加工精度和喷嘴材料都要与系统进行合理的匹配，这样在达到清洗效果的同时，还会减少对设备的损伤。

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.高压喷嘴的应力疲惫磨损。众所周知，喷嘴材料硬度是较高的，但当硬度高而韧性很低的时候，这种脆性材料受到气力较大的杂质粒子的撞击和冲击的情况下，可能会发生材料断裂磨损，形成喷嘴表面横向或者径向两种类型的裂纹。坚硬喷嘴的脆性断裂磨损。

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.

尽量减少这种磨损，就是要特别留意清洗介质的纯净性，尽量不要含有杂质，尽量降低对它的磨损机率和程度。

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.意外损害对喷嘴的危害。为了安全起见，尽管高压喷嘴口通常都设计成凹式，但我们如果不正确的使用和不能及时进行保养和维护，扇形喷嘴的偏移结构是很容易遭受到损害的。

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.

使用高压清洗机时要留意保护好喷嘴，减少磨损，延长它的寿命，就可以减少更换频率，可以降低高压清洗机的使用成本。高压清洗机在长期的运转工作过程中，必然会对各个零部件产生一定的磨损，但是，我们也可以通过采取一些预防措施，尽量减少这些磨损，延长高压清洗设备各个零部件的使用寿命。

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.
