彈簧支吊架主要用于電廠汽水管道或鍋爐設(shè)備、在運(yùn)行中產(chǎn)生熱位移及其設(shè)備裝置上。根據(jù)管道受力情況計(jì)算確定的彈簧支吊架工作和熱位移要求,將彈簧支吊架按照設(shè)計(jì)荷載進(jìn)行整定:即彈簧預(yù)壓并所定冷態(tài)荷載位置上;同時(shí)標(biāo)上冷態(tài)時(shí)的理論工作位置。
Boiler steaming-water pipe or in steam-water spring is mainly used for power equipment, the thermal displacement and its equipment in the operation of the device. Calculated and determined according to the pipeline stress situation of the work and the thermal displacement, steam-water spring will be carried out in accordance with the design load setting steam-water spring: the spring preloading and position set by the cold load; At the same time, the theoretical position to be in the cold.
一、彈簧支吊架在出廠前制造廠方進(jìn)行了整定,當(dāng)安裝了到管道和設(shè)備上后,作有關(guān)螺紋調(diào)整,將鎖定銷脫開(kāi),這時(shí)彈簧的實(shí)際承載就是設(shè)計(jì)所要求的冷態(tài)荷載。
A steam-water, spring manufacturing factory for setting before they go out, when installed on the piping and equipment adjust about the thread, the locking pin off, the spring is the actual bearing design requirements of the cold load.
二、型號(hào)、種類 可變式彈簧支吊架有四大系列,主要是由西北電力設(shè)計(jì)院設(shè)計(jì)的 T1、T2、T3、T4、T5型系列、 華東電力設(shè)計(jì)院設(shè)計(jì)的TH1、TH2、TH3型系列、TD系列(JB/J8130.2-1999) 化工設(shè)計(jì)院設(shè)計(jì)的VS系列,其系列的基本特性相同,承載力為20daN-21000daN。 結(jié)構(gòu)形式主要有懸吊式、支承式和并聯(lián)懸吊支承式。
Type, type variable type spring hanger has four big series, mainly by the northwest electric power design institute of design of T1, T2, T3, T4, T5 series, east China electric power design institute of design of TH1, TH2, type "TH3" series, the TD series (JB/J8130.2-1999) the VS series of chemical industry design institute of design, the series of the basic characteristics, the same bearing capacity of 20 Dan Dan - 21000. Structure forms mainly include the suspension type, bearing type and parallel suspension bearing type.
三、T、TH結(jié)構(gòu)形式和型號(hào)表示方法:本吊架根據(jù)安裝形式分為中間連接吊架彈簧TH1 、上下連接吊架彈簧TH2 、支架彈簧TH3 三種型號(hào)。 TH 1 又分為A、B、C三種類型; TH 1 A( T1 )為單耳連接吊架彈簧; TH 1 B( T2 )為雙耳連接吊架彈簧; TH 1 C為螺紋連接吊架彈簧; 這三種類型彈簧,主要用于懸掛在鋼梁、管梁、底板上。 TH 2 ( T3 )適用于安裝在鋼梁上; TH 3 ( T4 )主要用于擱置在基礎(chǔ)、鋼梁、樓板上; T5 并聯(lián)懸吊型。
T, TH structure form and model representation: the intermediate connecting suspension spring hanger according to the type of installation is divided into TH1, up and down link hanger spring TH2, support spring "TH3" three kinds of models. TH 1 is divided into A, B, C three types; TH 1 A (T1) is A single ear connected spring hanger; TH 1 B (T2) as the binaural link spring hanger; TH 1 C for threaded hanger springs; The three types of spring, is mainly used for hanging in the steel girder, illustrated the, on the floor. TH 2 (T3) is suitable for installation on the steel beam; TH 3 (T4) is mainly used to put on the foundation, beam, floor slab; T5 parallel suspension type.
四、VS、TD結(jié)構(gòu)形式和型號(hào)表示方法: 可變彈簧支吊架主要由圓柱螺旋彈簧、位移指示板、殼體及松緊螺母等零件組成??勺儚椈芍У跫馨窗惭b方式的不同,分為A、B、C、D、E、F、G七種型式。 A型----上螺紋懸吊型; B型----單耳懸吊型; C型----雙耳懸吊型; D型----上調(diào)節(jié)擱置型; E型----下調(diào)節(jié)擱置型; F型----支撐擱置型; G型----并聯(lián)懸吊型。
VS, TD structure form and model representation: variable spring pipe-hanger is mainly composed of cylindrical helical spring, dashboards, displacement and elastic nut shell parts. Variable steam-water spring according to the different installation way, divided into A, B, C, D, E, F, G seven types. Type A, type of thread hanging; B - monaural suspension type; C type - ears hanging type; D - type adjustment on hold; E - regulation under the suspended type; F type - type support on hold; G type - parallel suspension type。
