Setting spring hanger and hanger

The spring of the setting spring support hanger has a certain stiffness and can be deformed (displaced) under the action of external load. Setting spring support and hanger in the spring range of work, the pipe has a small deformation process, will not completely lose its load distribution, so as to control the load transfer. Setting spring support hanger is generally used in the place where the pipe section has thermal displacement in the vertical direction, causing the displacement of the pipe fulcrum. If the fulcrum is rigid support hanger, it will hinder the displacement of the pipe section, or make the pipe section out of the support hanger, resulting in excessive force and stress in the pipe. This phenomenon will not occur if the spring tube support and pipe crane are used. In the whole design process, attention should be paid to adjusting the amount of spring-supported hanger, strictly control the appropriate design according to the modeling standard of spring-supported hanger, reduce costs, and create greater profit zui.

There are two series of setting spring hangers, T1, T2, T3, T4, T5 and TH1, TH2, TH3, which are designed by Northwest Electric Power Design Institute and designed by East China Electric Power Design Institute. The two series have the same basic characteristics and are widely used in electric power, metallurgy, chemical, petroleum, textile and other industries. The system and its equipment.

Spring support and hanger usually adopt the method of lifting zero distribution, that is, the load of the support and hanger is distributed according to the condition that the vertical displacement caused by the pipe dead weight at each support point is zero. The advantage of the load distribution according to the lifting method is that the distribution of the self weight stress of the pipeline is relatively uniform. In engineering, the force of spring suspension frame is generally determined according to the principle of zero distribution of hot suspension. Hot suspension zero means that the force of spring suspension frame in hot state should be equal to that of pipe system in cold state. According to this principle, it is determined that the self-gravity of each supporting point in the whole pipe system is more uniform in the hot state, but the total load of each point in the pipe system will be shifted so that the load will not be uniform or even come out.

Spring suspension rack generally has important parts with large thermal displacement, and this characteristic is more and more widely used in thermal power plants, nuclear power plants, petroleum and chemical plants. The spring hanger is a mechanical part that uses elasticity to work. Spring suspension rack is small, but it is a universal basic component. It is used to control the movement of machine parts, ease the impact or vibration, store energy, measure force and so on. It is widely used in machinery and instruments. Its application fields involve almost all fields of national economy.
