Elektro Komponenten hose connectors German Elektro Komponenten models Elektro Komponenten prices

Elektro Komponenten hose connectors are connecting devices used to join metal hoses and pipes. Their model numbers are typically determined by factors such as material, connection method, size, and applicable working pressure. Different models have different characteristics and scopes of application, such as ferrule-type metal hose connectors, flange-type metal hose connectors, and swivel-type metal hose connectors. Selecting the appropriate metal hose connector model requires consideration of multiple factors, such as the temperature, pressure, fluid medium, service life, and connection method of the working environment. For applications under special conditions such as high temperature, high pressure, and strong corrosion, it is necessary to select high-quality metal hose connector models that can meet the requirements.

Dual-line main and branch pipes: From the lubrication pump to the oil inlets of all distributors, these lines withstand relatively high pressure. Cold-drawn seamless steel tubes made of 10 or 15 steel are typically used. Tubes with severe rust must never be used. Oil supply pipes: From the distributors to the oil inlets of all lubrication points (bearing housing oil holes), these lines withstand relatively low pressure. Drawn copper tubes are typically used, as they facilitate piping when bends are required. Cold-drawn seamless steel tubes or stainless steel tubes are also used. Hose connectors are used for connections at moving parts. Piping should avoid areas with high temperatures from radiation or cooling water spray, especially at hose connectors. Piping layout must not interfere with the operation of the host machine and other equipment; it must be safe, reliable, and convenient for work, observation, and maintenance. Piping should be arranged horizontally and vertically, neatly and aesthetically. Minimize bends or small-angle bends; use large-radius arcs to reduce oil flow resistance. In case of installation conflicts, smaller pipes should yield to larger pipes, and low-pressure pipes should yield to high-pressure pipes. Pipes crossing each other must not touch and should be separated by a certain distance. Joints of parallel pipes should be staggered to avoid affecting installation and disassembly. To facilitate disassembly and cleaning, union joints should be installed appropriately, but their use should be minimized to reduce the possibility of leakage. Determine the pipe length on-site based on the piping path determined according to item 8.2, taking into account the influence of the bending radius. Consider the impact of inserting various types of pipe connectors into the pipeline. Pipe lengths should be determined, cut, and pre-assembled section by section to facilitate on-site adjustments based on actual conditions. If all pipes are cut at once, accumulated errors will make piping difficult. Utilize cut short pipes wherever short sections are needed. If necessary, straight-through pipe connectors can be used to extend length, but the number of joints on a pipe section should be minimized.

After cleaning, the pipelines should be formally installed and greased as soon as possible. Tighten all pipe connectors section by section according to the printed matching marks, ensuring that the original o-type O-rings are reinstalled. All piping fixtures must be secure and not loose. All oil supply pipes can be connected to the distributor outlets and lubrication points after greasing. Metric general-purpose threads are denoted by uppercase M. Metric general-purpose threads are divided into coarse-pitch and fine-pitch threads based on pitch. Coarse-pitch thread markings generally do not specify the pitch; for example, M20 indicates a coarse-pitch thread. Fine-pitch thread markings must specify the pitch. General-purpose threads are used for the connection and fastening of mechanical parts. Coarse-pitch threads are commonly used for threaded connections, while fine-pitch threads offer slightly higher strength and better self-locking performance than coarse-pitch threads of the same nominal diameter. Pipe threads sealed by threads prevent leakage without the need for fillers or sealing compounds. Thread-sealed pipe threads come in two connection forms: cylindrical internal thread with conical external thread, and conical internal thread with conical external thread. The former connection provides sufficient tightness, while the latter is typically used only under high-temperature and high-pressure conditions.

Elektro Komponenten hose connector selection

Chemical equipment pipelines usually transport various corrosive fluids and require frequent flushing with solvents or water. When considering the corrosiveness of the medium, the primary concern should be the relationship between the pipeline seals and the medium. Nitrile rubber is widely used in hydraulic systems because it is compatible with standard hydraulic oils. At certain temperatures, nitrile rubber is also compatible with synthetic acetaldehyde, glycol-based chemical liquids, and plant-derived liquids. However, nitrile rubber is not suitable for contact with acidic media, benzene, or synthetic oils at high temperatures; in such cases, fluororubber should be used. Conversely, methane and refrigerant ammonia are only compatible with nitrile rubber. Therefore, most chemical stainless steel pipelines use rigid seals. When selecting pipe connectors, the maximum working pressure of each connector must be at least equal to the maximum set working pressure of the entire hydraulic system. Consider not only the pump outlet pressure but also the relief valve activation pressure. The maximum working pressure of hydraulic pipe connectors may vary depending on the sealing method or temperature changes: similarly, selecting elastic seals for connectors will yield higher working pressures compared to rigid seals.
