Pressure of high-pressure braided hose: the maximum working pressure that can be borne by long-term stable work; this pressure value must be greater than or equal to the maximum working pressure of the hydraulic transmission system
1. Pressure of high-pressure braided hose: the maximum working pressure that can be borne by long-term stable work; this pressure value must be greater than or equal to the maximum working pressure of the hydraulic transmission system (single-pulse working pressure or large pressure of the hydraulic transmission system).
2. The working pressure of the high-pressure braided hose test: reduce the pressure by 2 times for 60 seconds. There are no leaks and the working pressure value is reduced.
3. Engineering blasting working pressure: high-pressure braided hose generally refers to 4 times the pressure value.
4. Temperature range of high pressure braided hose: generally -40~100.
5. The basic entity model standard of the high-pressure braided hose is identified by the nominal diameter of the high-pressure braided hose, that is, the rounded nominal route DN.
6. Bending radius of high-pressure braided hose: a small bending radius that can be selected when working again under large working pressure, lower than the proposed bending radius will seriously affect the compressive strength of high-pressure braided hose. In addition, the length of the small parallel line between the high-pressure braided hose and the high-pressure braided hose connection transition section must exceed 1.5 times the diameter of the high-pressure braided hose.
7. Distribution of high-pressure braided hose components: To prevent the high-pressure braided hose from being damaged by stretching, shrinking, twisting or obtuse-angle friction, it cannot be applied in twisted conditions.
The rubber high-pressure braided hose carries out core forming, which means that the rubber high-pressure braided hose is formed on a hard core or a soft core. In order to better ensure that the rubber high-pressure braided hose is subjected to working pressure during the whole process of vulcanizing Water cloth (a roll of soaked wet rag within 10 cm wide), rope or lead is encapsulated, and the rubber is re-vulcanized. Vulcanization can use a vulcanization tank to immediately use a steam heat exchanger or to continuously vulcanize the rubber. Polyester staple fiber high-pressure braided hose adds short fibers into rubber products immediately, and then forms. The production process of high-pressure braided hose is simple and gradually replaces knitted high-pressure braided hose and clamp joints. Contemporary high-pressure braided hose production processes tend to be relatively highly continuous and automated. The application of thermoplastic rubber or plastic to the high-pressure braided hose can eliminate the vulcanized rubber processing process and greatly simplify the production process.
