Spring hangers is primarily used to power steam pipe or boiler equipment, running in the thermal displacement and its equipment. According to the pipeline force calculation to determine the spring hangers and thermal displacement requirements, the factory will spring hangers by design loads for setting: the spring preload and the cold load location; at the same time marked the theory theory cold work location.
Spring hangers in the factory manufacturing plant for the setting, when installed on the pipe and equipment for the thread after adjustment of the PIN disengaged when the actual load of the spring is the design of the cold loads.
Second, type, type
Variable-type spring hangers with four series, mainly by Northwest electric power Design Institute design of T1, T2, T3, T4, T5 series, the design of the TH1 Huadongdianlishejiyuan, TH2, TH3-series, TD series (JB/J8130.2-1999) and the chemical industry Design Institute design VS series, the series of the same basic characteristics, carrying capacity for 20daN-21000daN. Structure forms are hanging type, bearing type and parallel suspension bearing type.
(Iii), T, TH structure and model representation:
This hanger according to installation forms fall into the Middle connection hanger and down connection TH 1 spring hanger Spring 2, bracket spring TH TH 3 three models.
TH 1 is divided into A, B, C three types;
TH 1 A (T1) to the lug attached hanger spring;
TH 1 B (T2)-binaural connectivity hanger spring;
TH 1 C for threaded connection hanger spring;
The three types of springs, it is mainly used for hanging in steel, tube beam, backplane.
TH 2 (T3) is suitable for installation on a steel beam;
TH 3 (T4) is mainly used for shelving in base, steel beams, floor;
T5-parallel suspension.
(Iv), VS, TD structure and model representation:
Variable spring hangers is mainly composed of helical springs, displacement direction Board, shell and parts such as tight nut.
Variable spring hangers by installation, divided into A, B, C, D, E, F, G-7 type.
