High-pressure hose fittings overview and installation notes
There are many types of high-pressure hoses: high-pressure braid hoses, high-pressure winding hoses, high-pressure hose assemblies, mining high-pressure hoses, high-pressure hoses, and other varieties. He is widely used in coal, mining, chemical, mechanical, and automotive industries. . The extensive use of high pressure hose has also made his accessories widely used.
When it comes to high-pressure hoses, we always refer to high-pressure hose fittings. The hose fittings we have discussed in detail have also been analyzed. However, some people still do not understand his application and appearance. Today, we explain them again in detail. The basic concepts and pictures.
The joints of various high-pressure hose assemblies are divided into: A-type, B-type, C-type, D-type, E-type, F-type, H-type, flange-type and other national standards, and we can according to his curvature, such as: 30 degrees , 45 degrees, 75 degrees and even 90 degree bends and other joints, in addition to high pressure hose fittings we can custom processing such as the British system, the United States system of national standard joints. Speaking about his classification, let's talk about his installation notes:
(1) The hose must not bend excessively when it is moving or at rest, nor can it bend at its root, and it must begin to bend at least 1.5 times its diameter.
(2) The hose must not be pulled too tightly when it is moved to an extreme position and should be relatively loose;
(3) Try to avoid the torsional deformation of the hose;
(4) As far as possible from the heat radiation components hose, the necessary fashion insulation board;
(5) External damage to the hose should be avoided, such as long-term friction on the surface of the same component during use;
(6) If excessive deformation occurs due to the weight of the hose, there shall be support pieces.
