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. Spring hangers in addition to meeting the various functional requirements, but also want it to have sufficient strength in the working conditions and lifetime use does not produce any permanent deformation, but should also be light weight, small size, easy to manufacture and low prices. Some of these conflicting requirements, such as requiring sufficient strength tends to cause weight gain and increase in cost. Sometimes to fully meet these requirements is difficult. Therefore, in spring hanger design should first meet the functional requirements, followed by strength requirements, and finally on account of its economy. Usually spring hanger design steps should be: according to the requirements of use, select suitable spring shape, type and end structures. According to the given spring hanger position for example to allow the maximum diameter, minimum diameter, free height and deformation amount of the coil spring; plywood spring length, width _ the number plate, arc deflection and free state Higher) fix a spring contour size. Depending on conditions (such as temperature, ambient media, magnetic requirements for selecting suitable materials according to the load characteristics of the spring hanger conditions of use (for example, static load, dynamic load or impact load, repeated load or vibration loads, etc. ) determine the allowable stress, calculate a variety of specific geometric parameters of the spring and the manufacturing method includes a heat treatment procedure, including, where two of the plumbing system in spring specified requirements have not changes, so spring allowable stress design workers hanger spring material primarily choose to determine the allowable stresses calculate various specific geometry and manufacturing methods, the Wei material means spring hangers in a specified condition without fail the maximum allowable stress the long-term use.
