Description
Technical field
The present invention relates to field of shipbuilding, more particularly, to a kind of ultra-large type liquid pump installation and locating method peculiar to vessel.
Background technology
Stainless steel chemical tanker compares less novel ship as country's construction, and it is at a relatively high to build difficulty, at present I
The oil carrier for the 38000T chemical tankers construction different from the past that company builds, the ship type is using a current cabin state-of-the-art in the world
The a set of independent liquid pump system of the design pattern of one pump system, i.e. an independent liquid cargo tank, full ship amount to 43 cargo tanks, also
In the presence of 43 sets of independent liquid pump systems, so the core technology as ship cargo tank construction is that the peace of liquid pump in cabin
Dress, the accuracy of installation directly determine the whole liquefied cargo system success or not of the ship, because the ship cargo tank material selection is double
Phase stainless steel material, perforate are very prudent.
In original constructing operation, polishing groove, and the positioning at perforate center are coordinated using manual plasma cut
Using the location dimension in design drawing, there is following defect in such construction：
First, due to being manual perforate, the center of circle degree in hole is in the presence of very big error, and the shaping very irregular of groove, this is directly resulted in
The installation gap of last liquid pump pedestal crossing cabin part can not ensure, so as to cause the penetration weld of liquid pump and deck plane complete
Full penetration.
Second, on the determination at deck perforate center, original adoption is design drawing size, but liquid pump center is necessary
When liquid pump pedestal center and the bilge inhale well center and keep certain perpendicularity, but in actual building course, due to deck
Segmentation and bottom section precision are not to ensure to install without surplus, so certain error be present with design drawing, cause liquid pump
Pedestal center and oil suction well central perpendicularity deviation are excessive, beyond design requirement.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, it is fixed that the present invention provides a kind of ultra-large type liquid pump installation peculiar to vessel
Position method, can effectively ensure that the accuracy of liquid pump installation, avoids doing over again because error is excessive, so as to improve efficiency and section
