Due to its long-term use in mining, oilfield development, metallurgical forging, ships, plastic machinery, agricultural machinery, automated hydraulic systems, etc.,
the low-pressure air rubber pipe is easy to cracks.
Its cracking phenomenon usually has two kinds,slow type and sudden type.
The sudden bursting is more harmful. So, what is the reason for the bursting?
The crack reason of low-pressure air hose
1. we lift the equipment to the transport position, driving at high speed, on an uneven road surface,the high-pressure rubber pipe’ suspension produce a greater impact than original one;
at this time, the safety valve will have an immediate effect,leads to high pressure oil pipe burst.
2. Wrong use of “neutral” position.
During the operation, due to the unevenness of the ground, agricultural tools ups and downs;
because piston movement of the oil cylinder,the high-pressure hose pressure capacity generates, when it is in the “neutral” position,it ruptures.
3. The automatic return mechanism is abnormal, the joystick cannot jump back to the “neutral” position in time, the operator does not pull it back in time, the rubber hose is subjected to a large load for a long time,then bursts.
4. The opening pressure of the safety valve is adjusted too high, the high-pressure hose is overloaded for a long time and bursts.
5. Improper installation. Burst due to twisting, bending, wire layer wear, corrosion, local overload, etc.
6. The rubber hose is aging, cracked, damaged, due to long-term exposure to sunlight, contact with gasoline, diesel oil, etc. to corrode the hose.
