If the hose is damaged earlier, the possibilities of damage that occurs is: crack, tear (split), small leaks, improper hose length, friction, heat, twist, selecting the wrong hose, fitting one, or who is not laying appropriate.
Crack or tear in the outer layer (cover) hose is common and does not always mean a hose destroyed. The depth of damage is important. Therefore, it should be seen regularly, especially in high-pressure circuits.
Leaks as small as the tip of the needle holes are very difficult to detect. But a very small leak can grow and swell within a few weeks later, and can create a fire hazard or injury to the skin.
The length of hose handling can mean that it is too short or extended because the pressure is too long to give a chance to the dangers of moving parts. Therefore hose will be damaged. Friction hose cover up shabby, weakens the amplifier layer, so that will eventually damage the hose earlier. Clamping or protection of the hose is a method to overcome them.
The heat from the engine exhaust system and can damage the radiator hose. Make sure all hoses are placed away from hot parts or at least be given a baffle or shielded from direct contact.
Torsion can restrict the flow of oil and also damage the hose. Bend or bends are part of the design of the hose, but not puntirau. The main cause of torsion is when one end of the hose is not connected to the axis of the moving parts. To fix it, the hose is clamped to the end, where there is a twist start, the movement split into two parts hose (field).
If some torsion is unavoidable, it should be given as much freedom as possible. When connecting hoses, should be detained to avoid twisting as hardening of the connective end.
Selection of the wrong hose occurs when the tubes used are the wrong size or pressure class. The relationship between the size of the hose with the pressure received can be seen in the table in advance. Selection of the wrong hose can cause a variety of damages above. Errors may occur in connection connector replacement does not fit (according) to the size or model hose.
Destroyed at the suction inlet hose is another type of damage, it seems trivial. But it is possible that the inner layer of rubber hose suction channel when it starts to deteriorate, disintegrate into, as a whole closed the stream, without showing any symptoms (signs) outside dad destruction. The sound of the pump is noisy, decrease (reduction) of pressure or no movement at all is an indication of the collapse of the suction channel.
Penempatim improper is the main cause of damage to the hose. Included are the torsion and scratches, as well as sharp bends, hoses that are too long or short, too much use of a connector, and joining methods are wrong. Because so many possibilities of the cause, should be careful in taking steps to address it again.
