Hanger, Huaneng pipeline equipment, constant force spring hanger

Construction of Qualified spring hangers to be pre-assembled and assembly work immediately. From the engineering volume and technical complexity, the pre-assembly and assembly work spring hanger, complex and difficult job than to disassemble and clean up. In addition to the general parts and components assembly, but also for spring clearance measurement and adjustment of various by-clearance inspection and assembly and the shaft of the grinding and dealing with difficult issues. Spring hangers spring hangers commissioning test run on machinery and equipment aimed at a comprehensive test installation and construction process of construction quality spring hanger overall installation process, you may also find spring hangers in the design and manufacture on the problems. Since commissioning needs to be installed spring hanger machinery and equipment up and running, which can further examine spring hangers deficiencies in the installation process and non-standard parts, and can be adjusted and treated promptly, so that the machinery various performance parameters of equipment operation to meet the requirements of production and use. Spring hanger spring hanger acceptance of the machinery and equipment installed after the commissioning need to go through the test to see whether the index can be hand over the acceptance. Acceptance is to work construction unit, construction units of acceptance by the construction unit, while the construction is to be surrendered to assess Archives Project Quality grade II when the hand over, after full compliance with relevant state regulations, before allowing use of mechanical device is turned on. Pipe equipment characteristic spring hanger and hanger for installation of the pipeline option has a very important role. Straight pipe hangers stiffness due to stable and simple to manufacture, and therefore most widely used, cylindrical compression or tension spring to fall into this category, but it also limited to an average diameter of external load does not exceed the elastic limit of the material and the spring constant time is appropriate, if the alien load exceeds the elastic limit of the material, the material will result in yield caused permanent deformation, even after shed load, spring can not be restored to its original position, which is why the choice of pipeline plant spring hanger when the heat treatment process, the elastic limit of the material to a primary consideration sake. Spring hangers those incremental type characteristic curve, when the plumbing external load reaches a certain level, the stiffness increases dramatically, thus helping protect the spring. For example hanger inside the conical coil spring, due to the different average diameter of each circle, spring index is not the same, the index lower end of the upper end of the larger, rear springs under load, deformation start until the bottom of the first and tight as a whole, so practical and effective to reduce the number of turns of the spring, and then subjected to deformation are those of the turns of the spring index is small, thus sharply increased rigidity. Those leaving the friction loss characteristic loading and unloading do not overlap plywood, ring and disc spring hanger pipeline equipment, it can be made use of its damping or cushioning device characteristics.
