1. Lub tshav kub exchanger yuav tsum tsis txhob deformed, thiab fasteners yuav tsum tsis txhob xoob los yog lwm yam mechanically puas.
2. Thaum hoisting cov cuab yeej, hoisting ropes yuav tsum tsis txhob raug ntes ntawm cov kav dej txuas, cov kab teeb tsa, lossis cov phaj.
3. Qhov chaw txaus yuav tsum tau tseg nyob ib ncig ntawm lub tshav kub exchanger kom yooj yim txij nkawm.
4. Cov kav dej nkag thiab qhov hluav taws xob rau cov xov xwm kub thiab txias yuav tsum tau txuas nrog raws li cov kev taw qhia tau teev tseg ntawm cov chaw tsim khoom lub npe.
5. Cov kav dej txuas mus rau cov khoom siv hluav taws xob yuav tsum tau muab ntxuav kom tsis txhob muaj cov xuab zeb, vuam slag, thiab lwm yam khib nyiab los ntawm kev nkag mus rau hauv lub tshav kub exchanger thiab ua rau muaj kev thaiv.
6. Lub tshav kub exchanger yuav tsum tau mus kuaj hydrostatic ntawm 1.5 npaug ntawm nws lub siab tshaj plaws kev khiav hauj lwm siab. Rau cov chav dej, lub siab yuav tsum tsis txhob qis dua lub chav dej siab ntxiv rau 0.3 MPa; rau ntu dej kub, nws yuav tsum tsis txhob qis dua 0.4 MPa.
