What is the relationship between hose length and water flow rate
Ultra-high pressure (UHP) hose is a special material used in industry. As its name suggests, it works exclusively in high-pressure systems. Typical examples include hydraulic systems and high-pressure washing systems. In fact, this type of hose often faces harsh working environments. So you need to operate it properly to extend its service life. Next, let me introduce the correct ways to use UHP hoses.
First: Pay Attention to UHP Hose Fittings
When you install or disassemble high-pressure pipe joints, never use force or over-tighten them. This protects the inner and outer threads from damage. At the same time, apply lubricant to the outer surface of the threads. After disassembly, use a protective sleeve to cover the threads. This extra step keeps the threads safe when not in use.
Also: Note Other Factors Affecting Service Life
Other factors also have a big impact on the service life of UHP flexible hoses. For example, pressure fluctuations during the cleaning machine’s operation can shorten life. The opening and closing of the spray gun and control valve also affect how long the hose lasts.
Correct Usage Methods for UHP Hoses
During cleaning, try to avoid frequently opening and closing the handheld high-pressure spray gun. This reduces the impact of pressure pulses on the hose. In turn, it helps extend the hose’s service life. Besides that, pay special attention to the bends near high-pressure pipe joints. Sharp bends here can damage the hose. Moreover, coat the joints with anti-rust oil. This protects them from high temperatures, high pressure, and corrosion.
Never let the actual pressure exceed 1.25 times the hose’s specified pressure. If it does, the hose’s service life will drop by 50%. If you need to bend the hose, make sure the bending radius is not too small. In general, the radius should be at least 15 times the hose’s outer diameter. If it’s smaller, the steel wires on the hose’s outer side will stretch. At the same time, the steel wires on the inner side will compress. This reduces the compressive strength of the entire high-pressure pipe.
