Cause analysis of leakage of high pressure hose fittings

2022-09-16 Page view : 7 views

The causes of high-pressure rubber pipe fittings leakage are as follows: “ring” aging or deformation leads to leakage; Insufficient “ring” device causes uneven pressure or “ring” is cut to form a leak when connecting two planes; The “ring” is incomplete resulting in a loss of elasticity resulting in a leak. The molding; The ring groove is too deep and shaped. Leaks. To reduce the depth of the groove, a “” ring with the same outer diameter and thicker section must be selected from the scratch, or the sealing surface must be cut or ground with the groove so that the” “ring has sufficient elastic deformation (shrinkage should generally be between N 0.35 and 0.65 mm). For leakage of pipe fittings using oil-resistant rubber sheets, felt, mild steel cardboard, combined gaskets or sealants, regardless of the type of raw materials, it is necessary to check whether the seals are damaged, deformed, aging and rough, and then take corresponding measures. We are hydraulic hose fittings manufacturer.

The problem of high pressure hose fittings device

(1) In the process of moving or stopping, the hose should not be overly bent, nor should it be bent at the root, at least from 1.5 times the diameter;

(2) When the rubber hose moves to the pole position, it should not be too tight and should be relatively loose.

(3) try to prevent the change and deformation of rubber hose;

(4) The rubber hose should be kept away from the thermal radiation parts as far as possible, and the heat insulation plate should be used if necessary.

(5) External damage of rubber hose should be prevented, such as long-term conflict with the appearance of parts in operation.

(6)When the hose weight causes overheating deformation, the support should be set
