1. FTU installation height standard
The FTU installation height needs to be adjusted according to the equipment type and scenario, and the conventional reference standard is concentrated in the range of 0.4-1.8 meters.
1. Equipment type and installation height are closely related. "FTU" as an equipment abbreviation needs to specify the specific type. Based on similar equipment experience, the installation height should meet the three principles of operational convenience, maintenance accessibility, and safety compliance. The following are common equipment categories for comparison:
2. Reference for installation height of similar equipment 1 Firefighting equipment: • Fire pump coupler (wall mounted/above ground): The center of the water inlet is 0.7 meters above the ground • Underground water pump coupler: The center of the water inlet is 0.4 meters above the ground • Fire flow meter: The conventional installation height is 1.5-1.8 meters, and adjustments to the pipeline diameter and site conditions need to be considered. 2 Hydraulic control equipment: • Foot valve: standard height of 10-20 centimeters, additional 5 centimeters required when including fittings
III. Typical adaptation scenarios. ⊙ Industrial scenarios: equipment is mostly installed at around 1.5 meters, taking into account instrument visibility and collision prevention requirements. ⊙ Underground pipeline network: underground equipment height is usually controlled at 0.4-0.7 meters to avoid siltation and affect functions. ⊙ Public facilities: equipment involving personnel operation is recommended to be 1.2-1.5 meters wide, which meets ergonomic requirements. When implementing, it is recommended to combine the technical paramet
2. Can the underground water pipe network be accurately detected?
The underground water pipe network can be accurately detected.. There are currently multiple mature detection technologies available to achieve this goal, which can be divided into the following five categories:
1. Sound detection technology uses high-sensitivity electronic leak detectors to capture the faint sound produced by the friction of groundwater flow against pipelines or damaged areas.
. Professional personnel combine pipeline drawings to inspect each section of the pipeline, judge abnormal areas through changes in sound intensity, and gradually narrow down the range of leakage points. This technology has significant effects on metal pipelines, especially suitable for detection in low noise environments at night.Secondly, tracer gas positioning method injects tracer gases such as hydrogen and nitrogen mixed gases into the pipeline to be tested, and uses the permeation characteristics of gas molecules to scan the gas overflow point along the ground with a dedicated detector.
. This method breaks through the limitation of sound transmission and is particularly suitable for non-metallic pipelines (such as PVC pipes) or pipelines buried deep, with detection accuracy up to centimeter level. 3. Infrared thermal imaging detection uses an infrared thermal imaging device to capture changes in the surface temperature field and analyze
