Q: What do you mean by "DN" on hydraulic hose?: Hydraulic hose is mainly composed of liquid synthetic rubber, inner rubber layer, middle rubber layer, multi-layer reinforced layer and weather resistant synthetic rubber outer layer. The utility model is mainly used for hydraulic support and oil field development of a mine, and is suitable for engineering, construction, hoisting, transportation and automation hydraulic system to transport medium and water base fluid with certain pressure and temperature.

Q: How to determine the parker381 hose joint?: PARKER hose connector specifications: 1/4 "to 2", the connection form of DKO 24 cone, American NPT taper thread, JIC37 degree flared, ORFS American plane seal, JIS60 cone, JIS30 degree flared, SAE flange etc.. It can be divided into three series: detachable, buckle pressing and Push-Lok. The detachable series hose joint does not need special equipment when it is assembled, so it is easy to operate. It is especially suitable for field operation and can be reused. But because of the high price, fewer customers are used. Buckling type series high voltage because the connection is reliable and widely used, but the processing assembly need to withhold special equipment, so the majority of customers directly buy hose assembly. Push-Lok series are suitable for low voltage applications. They are widely used in automobile production lines because of their rapid assembly and disassembly, easy maintenance and replacement. They are also widely used in the die industry.

Q: There are several ways to connect the built-in rubber stop: The spot heat vulcanization method is a heat vulcanizing mould matched with a water stopping strip and a raw film vulcanizing heat junction. The construction is difficult, but the joint effect is ideal, which is suitable for the project with strict quality requirements.

Q: How long is the service life of the gas hose?: The service life of the hose is two years. It is recommended to change it once a year,

Q: Plastic metal hose connector model specification, who knows?: There are hoses, hoses, hoses, fittings, and steel tubes, with specifications ranging from 8 to 150

Q: Why should liquefied petroleum gas use strong rubber hose and liner?: In order to remind people of the leakage of liquefied petroleum gas in a timely manner, the processing plant often mixes a small amount of foul odor mercaptan or thioether compounds into liquefied petroleum gas, which is the source of special odor.

Q: Hose connector JB1885-77 what is the standard?: The reason of high pressure hose joint leakage are the following: "a" ring aging or deformation caused by leakage; the "C" ring assembly is not in place, the two plane connection or "C" uneven pressure ring is cut caused by leakage; "a" ring without compaction, the elastic deformation caused by leakage; the "C" ring spigot groove deep caused leakage. In this regard, the need to re select the same diameter and thick section "C" ring, can also be provided with a sealing plane rabbet groove of cutting or grinding, in order to reduce the rabbet groove depth, the "C" ring has enough elastic deformation (compression should be between 0.35-0.65mm).

Q: Production process and raw material of rubber: Process selection: the tensile strength is the limit ability to characterize products can resist tensile failure. The main factors affecting the tensile strength of rubber are: the main valence bond, intermolecular force and polymer chain flexibility of macromolecular chains.

Q: Do you need a hose connection to connect the ventilation pipe to the exhaust fan? Under what circumstances? Under what circumstances?: Must be added, never heard without the place, the wind turbine operation produces vibration, and galvanized sheet steel pipe is fixed at a certain place, if not, fan vibration, wind pipe vibration, the wind tube life are not long.

Q: What's the difference between hose and hose for compressed air?: In use, it is usually marked with color. For example, the intake is made of blue, and the exhaust is made red, but it is not necessary.
