It illustrates the method using single mast to hoist methanol synthesis reactor and dual masts to hoist hydrocracking reactor the uplifting-hoisting method using single crane as a master crane and the slipping method using dual cranes as master cranes and other methods such as using ring beam. The paper also discusses the crane safety margin when dual cranes used as master cranes together with top-board type liftinglug and moment distributor. Key words: reactor hoisting moment safety margin (49) Liftinglug Design and Acceptance Check in Heavy Equipment Hoisting PAN Wen-jiang(SINOPEC Ningbo Engineering Co. Ltd. Ningbo China) Abstract: Liftinglugs as important linking parts in equipment hoisting operation relate directly to hoisting safety of large equipment. The method and relevant requirements of large equipment hoisting are present in this paper regarding the liftinglug structural type design bearing capacity and positioning as well as the liftinglug manufacture welding quality control and acceptance check. In addition it is pointed out that the liftinhlug design and acceptance check are key links for heavy hoisting and should be well implemented according to the liftinglug design codes and the actual construction situation. Key words: heavy hoisting equipment liftinglug design acceptance check INNOVATION & PRACTICE (52) Development of Position Adjustor of Pumping Unit Motor MENG Xiang-jun(Shengli Oil Production Co. of Shengli Oilfield Dongying China)LUO Qin LI Hong-xin et al. Abstract: A newly developed motor position adjustor can effectively solve a series of problems in the position adjustment of pumping unit motor base such as mismatched distance between the adjustor and the motor base bad position adjusting stability. This adjustor is integrated of position adjusting base assembly and leading screw assembly. An ably designed self-locking device which applies backward reaction on the adjusting base caused by the motor base forward movement generated by leading screw rotating enables the motor position to be adjusted at discretion and stably in the existing slide rails. This adjustor has simple and reasonable structure and applicability for general purpose. It is the ideal equipment for motor position adjustment. Key words: pumping unit motor position adjustment equipment self-locking positioning safety guard a- gainst theft ENGINEERING DESIGN (54) Heat Exchanger Design under Fouling Condition ZHANG Qiong (SINOPEC East China Institute of Pipeline Design and Research Xuzhou China)SUN Jian-hong Abstract: In this paper the particularity of heat exchanger design under fouling condition is analyzed. Three different design methods under fouling condition i.e. the traditional fouling thermal resistance design method the currently developed clean coefficient design method and the area increasing percentage design method are clarified. Then these three methods are respectively used to calculate for the same case and obtain different results. Through the example of heat exchanger design under fouling condition it is shown that the currently developed clean coefficient design method and the area increasing percentage design method have better accuracy rationality and economy and the traditional fouling thermal resistance design method is too conservative to save engineering investment. Key words: heat exchanger fouling fouling thermal resistance design method clean coefficient design method area increasing percentage design method 6
