Relative mistake is not more than 1%.
Step 18：The water filling first of floating drum balance weight：By the requirement of Practical Calculation value to each floating drum balance weight internal water flooding, until
Meet design requirement.
After floating drum balance weight unlocks, because ship reception chamber structure is not that full symmetric generation distribution of weight load is uneven
The factor such as the fluctuation of water and steel wire rope tension difference causes synchronizing shaft initial torque in cloth, ship reception chamber, reduces as far as possible on synchronizing shaft
Initial torque, to system operation safety very weight.Therefore, accurate water distribution again is needed, it is equal by monitoring according to practical situation
The pressure value size of weighing apparatus oil cylinder and leveling cyclinder, takes out or water-filling respectively into the floating drum of floating drum balance weight, and debugging synchronizing shaft is initial
Design objective of the moment of torsion less than 50KNm.
Step 19：The unblock debugging of floating drum balance weight：After each floating drum balance weight water filling first, floating drum water level inside and title are checked
Weight and counterweight data are met after design requirement, and by ship lift system debug requirement, water-carriage system to vertical shaft fills sluicing, are made each floating
Cylinder balance weight floats, and the lock shaft 5 for operating each floating drum locking device is shunk in place, unlocks each floating drum balance weight；
The basis of floating drum balance weight water injection rate is that in minimum operation position, (ship reception chamber is in most in floating drum balance weight
Height navigation position) when do not deviate from the water surface, keep the minimum depth of the water submerging of design to be 0.2m (cylindrical section).
Step 20：The accurate water distribution of floating drum balance weight reduces synchronizing shaft moment of torsion：Analyzed according to synchronizing shaft torque detection data, it is right
Injected water volume inside each floating drum balance weight carries out accurate water distribution, finally meets the running quality requirement that synchronizing shaft drop is turned round；
Complete the construction of the Waterpower type ship elevator floating drum balance weight.
The step of floating drum bottom positioning section 14 be additionally provided between step 4 and step 5 adjusting so as to which lock hole center is total to
The index such as face degree and levelness meets quality standard.
After the completion of each middle node welding of floating drum, need to be by design requirement in inner support and reinforcing plate.
In step 20, the accurate water distribution of floating drum balance weight reduces the method for synchronizing shaft moment of torsion and is：
Step 20-1：Calculated according to water injection rate computing formula
1. Waterpower type ship elevator lift system weight balancing formula：
Ship reception chamber gross weight+the steel wire rope of the single set floating drum balance weight weight × total tricks of floating drum balance weight=load standard depth
Transfer weight × 2- floating drums flood buoyancy × total tricks of floating drum balance weight that water is 0.2m；
2. single set floating drum balance weight adds water injection rate：
Single set floating drum balance weight adds water injection rate=mono- set floating drum balance weight weight-running block weight-connecting bracket and axle
Weight-mono- set floating drum balance weight net weight；
Step 20-2：Single set floating drum balance weight plus water injection rate are calculated according to above-mentioned formula；
Step 20-3：According to above-mentioned value of calculation, take out or water-filling to each set floating drum balance weight respectively, debugging synchronizing shaft is initially turned round
Design objective of the square less than 50KNm.
