The cleaning effect of high pressure cleaning machine is based on the premise of reasonable maintenance of equipment, which has a greater impact on the cleaning effect of high pressure cleaning machine is the state of the high pressure nozzle, the following points are particularly critical:
1, high pressure cleaning machine in different fields of cleaning operations to a reasonable selection of nozzles. The selection and material of the nozzle directly affect the performance and cleaning effect of the high pressure washer, each material of the nozzle has its own suitable application field, small changes in the internal components of the nozzle can produce a large effect, no one nozzle can be suitable for all applications. Therefore, the aperture of the nozzle, the nozzle structure design, the nozzle processing accuracy and the nozzle material should be reasonably matched with the system, so as to achieve the cleaning effect, but also reduce the damage to the equipment.
2, the correct installation. Off-axis gaskets, over-tightening or other positional changes can have adverse effects; During installation and cleaning, the high pressure nozzle may be accidentally damaged due to the use of incorrect tools.
3. Accidental damage to the nozzle. For safety reasons, although the high-pressure nozzle is usually designed to be concave, the offset structure of the fan nozzle is easy to suffer damage if we do not use it correctly and do not maintain and maintain it in time.
4, high pressure nozzle stress fatigue wear. The hardness of the nozzle material is high, but when the hardness is high and the toughness is very low, the brittle material may be subjected to the impact and impact of impurity particles with larger strength, and the material may fracture and wear, forming two types of cracks on the nozzle surface, transverse or radial. Brittle fracture wear of the hard nozzle. To minimize this wear, we should pay special attention to the purity of the cleaning medium, try not to contain impurities, and try to reduce the probability and degree of wear on it.
