What to pay attention to when using hose assemblies
When using a hose assembly, it is important to pay attention to the following points to ensure its safe and effective operation:
1、 Basic usage precautions
Applicable materials and temperatures:
Hoses can only be used for transporting specified materials and cannot be changed arbitrarily, otherwise their service life may be shortened or damaged.
The medium temperature should be controlled between -40 ° C and+120 ° C to avoid exceeding this range and causing a decrease in hose performance.
Length and bending radius:
Considering the length variation of hoses under high pressure and the length variation caused by mechanical movement, the length of hoses should be used correctly.
The bending radius should not be too small, generally greater than 9 times the outer diameter. There should be a straight section at the junction of the rubber hose and the joint that is greater than 2 times the outer diameter of the pipe.
Avoid extreme conditions:
Do not directly contact or approach open flames to avoid damage to the hose caused by high temperatures.
Avoid extreme bending of the hose to reduce wear and reduce strength.
2、 Installation and maintenance precautions
Avoid heat sources and mechanical friction:
When arranging hoses, it is advisable to avoid heat sources as much as possible, such as engine exhaust pipes, and if necessary, use sleeves or protective screens.
If the hose may cause friction with the mechanical surface during operation, protective devices such as hose clamps or springs should be used.
Installation status:
During installation, keep the hose loose and should not be in a tension mode to avoid hose expansion and strength reduction under pressure.
During installation, do not twist the hose to avoid reducing its strength and loosening the joint.
Joint connection:
The connector should be tightened on the hose instead of the hose to ensure the firmness of the connection.
Regularly check the connection status of connectors and hoses to ensure no leaks or looseness.
Inspection and replacement:
If the hose is configured on critical components, it is recommended to conduct regular inspections and replace it based on usage and lifespan predictions.
When cutting steel wire reinforced hoses and fiber steel wire composite reinforced hoses, attention should be paid to the potential harm caused by exposed steel wires.
3、 Operation precautions
Slowly operate the valve:
When applying pressure, it is necessary to slowly open/close any valve to avoid creating shock pressure and damaging the hose.
Avoid crushing:
Do not use vehicles or other vehicles to crush the hoses to avoid damage.
Following the above precautions can ensure the safe and reliable operation of the hose assembly and extend its service life.
