Although hydraulic oil hoses have a relatively longer service life, improper use can still affect their lifespan. What factors can influence the lifespan of hydraulic oil hoses?
One, Pressure Matching
When selecting and using super-hydraulic hoses, the size should be based on the working pressure. If the pressure used exceeds 1.25 times the specified pressure, the lifespan of the hydraulic hose can be reduced by 50%.
Hydraulic hose lifespan is significantly affected by the pressure fluctuations of ultra-high-pressure washers during operation. Pressure surges occur during startups and shutdowns, leading to increased fluid pressure. Therefore, when purchasing hydraulic hoses, it's advisable to select ones that can withstand 1.5 times the actual working intensity to greatly extend their service life.

Two: Bore Matching
When selecting hydraulic oil hoses, it is essential to adhere to the requirements of the ultra-high-pressure cleaning machine's main unit. Changes in the inner diameter of the hoses can affect the working impact force and system balance. Experiments show that replacing a 4mm hydraulic oil hose with the specified 5mm diameter hose results in a lifespan reduction of 3/1.
Avoid bending.
During operation, the super-high-pressure cleaning machine should avoid bending the hydraulic oil pipes. If bending is unavoidable, ensure that the bend radius of the hydraulic oil pipe is not too small, otherwise the inner steel wire may be compressed, affecting the service life of the hydraulic oil pipe.
