Causes of Damage of High Pressure Rubber Hose

Manufacturing quality is poor
(1) High Pressure Rubber Hose The inner and outer layers of the pipe wall are made of oil-resistant rubber, in the middle of (2 to 4 layers) cross-woven steel wire or wound wire. Poor quality of the hose will appear: uneven thickness of the hose wall; wire weaving too tight, too loose or too few layers of steel; hose deformation after deformation (elongation, shortening or bending deformation) larger; outer plastic Poor air tightness leading to corrosion of steel wire; poor seal inside the high pressure oil easily into the steel wire layer; adhesive layer and wire layer adhesion. The above situation will reduce the bearing capacity of the hose, and ultimately burst in the weak wall of the tube.
(2) Hose and fittings when the selection of the amount of pressure withheld and withhold the speed of improper, or joint structure and material, size selection is unreasonable, can lead to hose and connector pressure too tight or too loose, resulting in joint damage at the early stage.
If the pressure is too small, that is, when the pressure between the joint and the hose is too loose, the hose may be disengaged from the joint in the initial use under the influence of oil pressure. If the amount of pressure is too large, the joint and the hose are compressed Too tight, easily lead to local damage to the inner hose, resulting in cracks, high-pressure oil from the rupture directly into the wire layer, and then along the gap between steel wire fleeing coat tail, or along the wire layer has been sneaked up somewhere together, So that the outer layer of plastic produced drums or even rupture. Hose and fittings in the assembly, if the fast withholding speed, likely to cause damage to the inner rubber and wire layer fracture, so that the hose in use prematurely damaged.
(3) In addition, the joint design is unreasonable, poor quality of processing, can also cause damage to the glue; if the joint material selection properly, easy to produce deformation in the withholding process, thus affecting the quality of withholding to shorten the hose life.
Improper use
Under the premise of quality assurance, if used improperly, will greatly shorten the hose to life. In practice, most High Pressure Rubber Hose damage is due to improper use caused.
(1) By frequent, severe pressure shock. High Pressure Rubber Hose burst, generally not due to withstand the static pressure is too large due to, but with the impact of the severity and frequency of the impact. Construction machinery in the operation, the oil pipe will be repeated within the oil suddenly increased or decreased, which constitute the frequent pressure on the tubing impact, leading to increased oil seal damage to the Ministry, the hose appears blistering and rupture and pipe joints loose seepage Leakage phenomenon. So in operation, the stem cannot be too much to pull, be sure to gentle.
(2) The use of oil temperature is too high. Engineering machinery operations, the hydraulic system due to power loss leaving the oil fever, coupled with the impact of outside temperature (especially in the summer), can make the oil temperature increased dramatically. The higher the oil temperature, the more aging rubber, elastic deterioration, strength and sealing performance decreased, the hose will soon burst. Therefore, in the operation, when the hydraulic system temperature rise is too high, too fast, it should promptly identify the cause, be excluded; summer operations, especially continuous operation, should take the necessary cooling measures.
(3) Hose selection, installation is unreasonable. In the replacement of High Pressure Rubber Hose, the length of the selected hose, wire layer, the connector shape and size should be reasonable, and should minimize the degree of hose bending; tighten the nut joints, do not make the hose distortion, Bending and twisting will greatly reduce the service life of the hose; for some parts of the prone to friction should take protective measures to prevent the hose burst due to wear and tear.

Thinking about Purchasing High Pressure Rubber Hose

Rubber hoses are used to transmit everything from water and air, to concrete, dust, and gravel, are used in the chemical industry to carry solvents, acids, and petrol, and are even used in the food industry to carry many different types of foods, fats, oils, and air.
Take a look at a handful of different considerations you will have to make before purchasing High Pressure Rubber Hose.
The Dimensions
The first consideration is what sort of dimensions you will need for your High Pressure Rubber Hose. It is available with different diameters inside and outside, at different lengths and with different tolerance levels. You will need to know exactly what you require before buying something that is not the right size for its purpose.
The Substance that is to be carried through the hose
The next consideration you will have to make before purchasing is that of the substance that you plan on putting through it. There are different types of rubber hoses that are suited to liquids, gases, or solids being put through them. Additionally, the concentration and temperature of the substances will all have a factor to choose.
What Application it will be Used For
Then you will have to consider what the application the hose will be being used for. Will it be to provide pressure, will it be used as a vacuum and will it require a certain flow capacity? Each of these considerations will have an impact on what is perfect for your needs.
Any External Conditions
The final consideration is what the external conditions are going to be. Will the hose be used in a freezing or extremely hot environment? Will there be outside chemical influences? Will the hose need to be UV and ozone resistant? You will have to answer all of these questions before making your choice of rubber hose.
Summary
As you can see Find Article, it is not as simply as just selecting a High Pressure Rubber Hose in your favorite color. You have to make a number of different considerations to ensure that your rubber hose is going to give you the performance that you require. Get the decision wrong and you could find that the hose fails which will lead to a lot of additional costs.
