What matters should be paid attention to to make the hose assembly last longer?

The high-pressure hose assembly is used to transport petroleum-based (such as mineral oil, solvent oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) with a certain pressure and temperature, and mine Hydraulic support, oil field development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and liquid transportation in the mechanization and automation of hydraulic systems in various industrial sectors

Always pay attention to these places will make your high pressure hose assembly last longer

Improper application

Under the premise of ensuring quality, improper use will shorten the service life of the hose assembly. In fact, most of the damage to the high-pressure hose assembly is caused by improper use.

Subject to repeated and severe stress. The burst of the high-pressure hose assembly is generally not caused by excessive static pressure, but is related to the severity and frequency of the pressure shock.

During the operation of construction machinery, the sudden increase or decrease of oil pressure in the tubing occurred repeatedly, causing repeated pressure shocks on the tubing, resulting in aggravated damage to the oil seal, blistering and cracking of the rubber tubing, and leaking and loosening of pipe joints. Therefore, during operation, the valve stem should not be pulled too tightly, but it must be steep.

The working temperature of the oil is too high. During the operation of construction machinery, due to the power loss of the hydraulic system and the influence of outside air temperature, the oil temperature rises sharply (especially in summer). The higher the oil temperature, the easier the bananas will age, the worse the elasticity, the lower the strength and sealing function, and the hose will burst quickly.

During operation, when the temperature of the hydraulic system rises too high or too fast, the cause should be found out and cleaned in time; during summer operation, especially during continuous operation, necessary cooling measures should be taken.

The hose assembly selection and device are unreasonable. When replacing the high pressure hose assembly, the length of the hose assembly, the number of steel wire layers, the shape and size of the joint should be reasonable, and the bending of the hose should be as small as possible

When tightening the connecting nut, do not deform the hose assembly. Excessive bending and deformation will reduce the service life of the hose; some simple conflicting parts should be protected to prevent the hose assembly from bursting due to wear.
