The primary cause of wear on the nozzles of high-pressure cleaning machines.

The wear of nozzles on high-pressure cleaning machines is a common issue that affects the efficiency of equipment cleaning. The root causes of this problem are closely related to fluid characteristics, impurity effects, material compatibility, and operational maintenance. Specifically, it can be categorized into four aspects:

1. Erosion and wear caused by high-pressure water jets.

This is the primary factor contributing to the wear of the nozzles. When in operation, high-pressure water flows through the narrow aperture of the nozzle at extremely high velocities, continuously striking the inner wall and the edge of the outlet, causing fatigue and wear of the metal material. The higher the pressure and the faster the water flow, the more pronounced the erosive effects become. Over time, this can lead to an increase in the diameter of the nozzle’s aperture and a disarray in the shape of the jet stream.

2. Abrasive particle wear through cutting.

The sand, rust, and other hard impurities in the cleaning water, or the concrete and paint particles that have fallen off the surface of the objects being cleaned, are carried along by the high-velocity water flow through the nozzle. These particles act like cutting tools, constantly scratching the inner surface of the nozzle, causing irreversible scratches and wear. This significantly reduces the lifespan of the nozzle.

3. Issues related to the compatibility of materials and operating conditions.

The wear resistance of the nozzle material directly determines the rate of wear. Ordinary plastic and low-hardness alloy nozzles are unable to withstand high-pressure impacts and particle abrasion, making them highly prone to wear. In contrast, nozzles made of materials like stainless steel and tungsten carbide, which are highly wear-resistant, are more durable. Additionally, high-temperature cleaning operations can reduce the hardness of the nozzle material, accelerating its aging and wear.

4. Inappropriate operation and maintenance deficiencies.

Illegal operations can directly damage the nozzle, such as when the nozzle collides with a hard object, when it is operated at excessive pressure, or when excessive force is applied during disassembly, causing deformation. Failing to promptly clean out residual impurities within the nozzle after operation can lead to localized corrosion, which further exacerbates wear and tear.
