Rubber Hose Rubber Hose To Bear The Force Aug 10, 2017

Rubber Hose Rubber hose to bear the force

(1) rubber hose wall inside and outside are oil-resistant rubber, the middle (2 to 4 layers) cross braided steel wire or wound wire. Poor quality rubber hose will appear: rubber hose wall thickness uneven; wire weaving too tight, too loose or too few layers of steel; rubber hose deformation after deformation (elongation, shortening or bending deformation) Large; poor adhesion of the outer layer of steel wire caused by corrosion; poor adhesion of the inner layer of rubber and high pressure oil easily into the wire layer; glue layer and the wire layer of insufficient adhesion. The above situation will make the rubber hose to bear the force to reduce the final weakness in the wall there burst.

(2) rubber hose and joint assembly when the amount of buckle and buckle speed improper selection, or connector structure and material, size selection unreasonable, can lead to rubber hose and joint pressure too tight or too loose, resulting in joints Early damage.

Assembly, if the buckle pressure is too small, that is, between the joints and rubber hose pressure too loose, the role of oil under the rubber hose in the early use may be out of the joint; if the buckle is too large, then the connector And rubber hose pressure too tight, easily lead to the inner layer of the rubber hose by local damage, resulting in cracks, high pressure oil from the rupture directly into the wire layer, and then along the gap between the wire to the tail of the jacket, or along The wire layer to a place to accumulate, so that the outer glue to produce drums or even rupture. Rubber hose and fittings in the assembly, if the buckle speed too fast, likely to cause damage to the inner rubber and wire layer fracture, so that the use of rubber hose in the premature damage.

(3) In addition, the connector design is unreasonable, poor processing quality, can also cause damage to the inner rubber; if the joint material selection improperly, in the process of buckling prone to deformation, thus affecting the quality of rubber, rubber hose life shortened.

Improper use

In the quality of the premise, if used improperly, will greatly shorten the rubber hose to life. In practice, most of the rubber hose damage is due to improper use caused.

(1) by frequent, severe pressure shocks. Rubber hose burst, generally not due to bear too much due to static pressure, but with the severity of the impact of pressure and the number of times. Engineering machinery in the operation, the tubing will repeatedly appear in the sudden increase or decrease in oil pressure, which constitutes a frequent pressure on the tubing impact, resulting in the Department of oil seal damage increased, rubber hose bubble and rupture and pipe joints Loose leakage phenomenon. So in operation, the stem of the pull can not be too much, must be gentle.
