彈簧支吊架的冷態吊零及熱態吊零(中英文)
  工程上,一般按熱態吊零的載荷分配原則確定彈簧支吊架的受力。所謂熱態吊零,是指彈簧支吊架在熱態時承受的力應等于冷態時由管系分配給它的力。按這樣的原則確定的彈簧支吊架受力使得整個管系中各支撐點承受的自重力在熱態時比較均勻,但在熱態時管系中各點的總載荷會因位移荷載的作用而不再均勻甚至會出現嚴重的不合理現象,為此,工程上有時也采用冷態吊零的載荷分配原則。所謂冷態吊零是指彈簧支吊架在冷態時承受的載荷取冷態時由管系分配給它的載荷。與熱態吊零相反,此時在熱態情況下管系各支撐點承受的自重載荷已不在均勻,而總載荷(包括位移載荷)則是自然分配。
  Engineering, general lift by hot zero load distribution principle of  steam-water spring force is determined. Hot zero, refers to the steam-water  spring bears should be equal to the force while in hot cold allocated by the  piping system to its power. Steam-water determined according to the principle of  this spring force makes the whole piping system of each point on the gravity of  even when hot, but in the hot pipe of each point in the total load will not  uniform because of the action of displacement load may even appear serious  unreasonable phenomenon, therefore, the project is also sometimes used cold  crane load distribution principle of zero. Steam-water cold hung zero refers to  the spring in the cold when carry the load by piping when you pick up the cold  load assigned to it. Contrary to lift hot zero, this time under the condition of  hot piping each strong point under the dead weight uniform load is no longer,  and the total load (including displacement load) is a natural distribution.
  為防止可變彈簧支吊架引起管系在熱態或冷態時有較大的載荷轉移,工程上常控制它的載荷變化率不超過25%。根據這一限制條件,就可以確定彈簧支吊架的剛度  k。在確定彈簧支吊架的剛度時應遵守這樣一個原則:在彈簧支吊架能滿足管系熱態和冷態的承載要求而且載荷變化率不超過規定值的情況下,應盡可能選用剛度最小(指最小規格和最小允許位移值)的彈簧。按這樣的原則選取的彈簧支吊架,其安裝尺寸最小,價格最便宜,而且實際的載荷變化率最小,探傷機。
  To prevent variable spring caused steam-water piping in hot or cold have  larger load transfer, load which usually control it in engineering rate less  than 25%. According to the restrictive conditions, can determine the steam-water  spring stiffness k. When determining the steam-water spring stiffness should  follow such a principle: in the steam-water spring can meet the piping hot and  cold load requirements and load change rate is less than specified value, should  as far as possible choose stiffness least (minimum specifications and minimum  allowable displacement value) of the spring. Selected according to the principle  of the spring hanger, its minimum installation size, price the cheapest, and the  actual load rate, minimum inspection machine.
  彈簧支吊架主要用于電廠汽水管道或鍋爐設備、在運行中產生熱位移及其設備裝置上。根據管道受力情況計算確定的彈簧支吊架工作和熱位移要求,本廠將彈簧支吊架按照設計荷載進行整定:即彈簧預壓并所定冷態荷載位置上;同時標上冷態時的理論理論工作位置。彈簧支吊架在出廠前制造廠進行了整定,當安裝了到管道和設備上后,作有關螺紋調整,將所定銷脫開,這時彈簧的實際承載就是設計所要求的冷態荷載。
  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  in the work and the thermal displacement of the steam-water spring requirement,  our factory 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 working position to be in the cold. Steam-water  spring factory for setting before they go out, when installed on the pipeline  and equipment, adjust relevant thread, to fix the quotas for marketing release,  then spring is the actual bearing design requirements of the cold load.
