Murrelektronik hose fittings Germany Murrelektronik model Murrelektronik price

Murrelektronik hose fittings connect different hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and some auxiliary components such as level gauges, thermometers, pressure gauges, etc.) to form a closed-loop hydraulic system. Hydraulic pipe fittings are accessories that serve a connecting role in this process. Hydraulic pipe fittings are detachable connectors between oil pipes and oil pipes, or between oil pipes and hydraulic components. They should meet the requirements of easy assembly and disassembly, reliable connection, reliable sealing, small external dimensions, high oil flow capacity, low pressure loss, and good manufacturability. Hydraulic pipe fittings are widely used in various aspects of our daily lives. They are mainly used in hydraulic piping systems in industries such as energy, petrochemicals, electric power, ships, automobiles, rail transit, mining, metallurgy, steel plants, offshore engineering, and construction machinery. Construction machinery is where hydraulic pipe fittings are most extensively used.

Murrelektronik hose fitting precautions

Avoid impacts and drops during handling and storage to prevent damage to interfaces and internal parts. When installing on high-temperature fans, ensure concentric installation as much as possible to ensure proper operation of the rotary joint. The connection between ferrule fittings and pipelines must use hoses; rigid connections are strictly prohibited. The inlet and outlet of ferrule fittings should be directly connected to hoses as much as possible to reduce the auxiliary weight on the ferrule fitting and extend service life. For the assembly of the inner tube of the ferrule fitting, pay attention to dimensional fit and weight support. For the fit between the inner tube and the joint of an internal-rotation rotary joint, a tolerance fit of H8/e7 is recommended. The support and anti-rotation of the ferrule fitting should be appropriate; generally, the rod diameter should be 2mm smaller than the anti-rotation hole to avoid affecting the free adjustment and compensation of the rotary joint. The perpendicularity of the pipe end face to the axis should be less than 0.50. Remove burrs from the end face and chamfer 0.2×450. Apply an appropriate amount of grease to the threaded part and the contact cone surface. Install the ferrule fitting and nut, paying attention to the direction. Hold the pipe fitting and press the end face against the shoulder of the joint body. Mark the ferrule fitting and tighten the nut. Ensure the pipe fitting does not rotate, tightening by 1.3~1.5 turns. Remove the nut and check the cutting-in condition of the ferrule.

Murrelektronik hose fitting usage

The connection between hose fittings and hoses is generally completed using a hose crimping machine. First, cut the hose to the required size, then strip the outer layer of the sized hose, install the hose fitting, and finally crimp it with the hose crimping machine. The specific steps are as follows: 1, select the appropriate hose and cut it to the specified length. 2, strip the outer rubber from both ends of the hose. 3, select the appropriate type of hose fitting. 4, sequentially install the fitting core mandrel (requires oil application) and the hose fitting outer sleeve. 5, crimp with the crimping machine, paying attention to selecting the appropriate crimping amount. 6, after crimping is complete, clean the rubber debris from the inner wall of the hose, then install the dust cap, sealing ring, and retaining ring.

Murrelektronik hose fitting features

Threaded fittings refer to pipe connectors with threads. They are one of the most common pipe fittings in industry and daily life. Threaded fittings make pipe connections simpler and easier to disassemble and replace, greatly saving on pipe connection costs. Threaded fittings generally include threaded elbows, threaded tees, threaded union joints, threaded caps, threaded couplings, threaded reducers, threaded plugs, threaded male connectors, bushings, etc. Threaded fittings used in industry are generally made of metal and have high pressure resistance. Materials include carbon steel, stainless steel, alloy steel, brass, etc. Materials for threaded fittings used in daily life generally include PC, PVC, PE, PPR, etc.
