water cannon/monitor for fire fighting system

Test Items

Appearance

Casting surface should be smooth, no cracks, porosity, shrinkage, trachoma and other effects of intensity and performance defect. Welds shall be smooth, no welding, burn, scar tumour and other damage strength and appearance quality defects. Fire monitor the outer surface of the paint layer shall be smooth, uniform, no bubbles, obvious scar, crack, affecting the appearance quality defects.

manoeuvrability

Fire fighting monitor pitching rotation mechanism, horizontal swing mechanism, the control handle ( wheel ) should be flexible operation, safe and reliable transmission mechanism. Fire fighting gun pitching rotation mechanism with self-locking function or a locking device. Portable fire fighting monitor in the whole level rotation angle range minimum elevation angle injection should be stable and reliable, with no sliding and overturning phenomenon.

decayresistance

Fire fighting monitor should be adopt corrosion-resistant materials or the materials by the anti-corrosion treatment, so to meet the corresponding use of the environment and medium anti-corrosion.
