Technical field
The present invention relates to shipbuilding field, more particularly to a kind of oil ship goods tank Cargo Oil Pump installation method.
Background technology
Oil tanker(Oil Tanker), it is being commonly called as oil carrier, refers to the liquid cargo carrier oceangoing ship of carrying bulk oil or product oil.
The ship of the various oils of bulk shipment is broadly referred to, the product oil of oil, various animals and plants in addition to transporting petroleum, are shipped
Oil, natural gas and oil gas of liquid etc..
Boiler, propeller, electromotor, pump are also equipped with oil tanker oil removal box and the outer oil tanker of pipeline(Handling on big oil tanker
Pump can up to ten thousand tons of liquid of pump per hour)And extinguishing device.
When oil ship goods tank deep well pump is installed, using vertically arranged method, due to the pump housing it is long, between motor and pump head by
A piece driving major axis, needs accurately to cash during installation, and installation requirement is high, and current mounting process is complicated, and installation accuracy is low, shadow
Building berth construction period is rung.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of process is simple, installation accuracy height and the high oil tanker of installation effectiveness
Oil cargo tank Cargo Oil Pump installation method.
To solve above-mentioned technical problem, the technical scheme is that:A kind of oil ship goods tank Cargo Oil Pump installation method, its
Innovative point is:Methods described is the installation site of Cargo Oil Pump first in positioning school, then using the method for lifting by deep-well
Pump is vertically mounted in oil cargo tank.
Further, comprising the following steps that in the positioning school:
(1)Plank makes and installs:One and Cargo Oil Pump pump head size identical plank are made, and is marked on plank
Each gripper shoe locality, then the center according to Cargo Oil Pump in drawing, determines Cargo Oil Pump in oil suction well in practice
Heart position, is then put in template in oil suction well, and plank center is consistent with well center is inhaled;
(2)Gripper shoe and guide plate are installed:According to drawing, gripper shoe is welded on Cargo Oil Ceiling, the support Board position
With step(1)On middle plank, the gripper shoe locality of labelling is consistent;Then it is directed to plate to be connected with gripper shoe;
(3)Flange in school is installed:In high-ranking officers, flange is fixed in Cargo Oil pump mount base by four pins, and the flange in school
Place optical instrument or laser device in center;
(4)Cargo Oil Pump base stand location:Cargo Oil pump mount base peace is opened on main deck at the top of oil cargo tank according to drawing bore size
Dress hole, is placed on Cargo Oil pump mount base in Cargo Oil pump mount base installing hole by optical instrument or laser device or plumb line, notes school
Centrage angle is 90 ° to middle flange from the bottom up;
(5)Cargo Oil pump mount base is installed:After the completion of in Cargo Oil Pump base stand location school, will be main at the top of Cargo Oil pump mount base and oil cargo tank
Deck spot welding is fixed, and Cargo Oil pump mount base can deviate guide plate centrage+10 millimeters;
(6)In Cargo Oil pump mount base school and full weld:Flange and Cargo Oil pump mount base gap, gap in school are checked with clearance gauge before in school
0.4 millimeter need to be less than, then reaffirm Cargo Oil pump mount base away from oil suction well by optical instrument or laser device or plumb perpendicular
Distance from bottom, it is such as correct, then by Cargo Oil pump mount base full weld.
Further, in the step (6) in Cargo Oil pump mount base school and during full weld, using deep penetration welding, weld bead height is
6mm。
Further, the method for the lifting is comprised the following steps that:
(1)Prepare before lifting:In a pre-installation, terminate painter in all welding, sandblasting, polishing, cabin cleaning and cabin
Make, then confirm that pipeline does not affect Cargo Oil Pump outlet(discharge) flange on main deck, finally adds pad in Cargo Oil pump mount base;
(2)Lifting:Two hangers are installed in Cargo Oil Pump exit position first, with two loop wheel machines by Cargo Oil Pump from horizontal level
Upright position is lifted to, after Cargo Oil Pump is lifted to upright position, wherein a loop wheel machine lifting makes Cargo Oil Pump slowly leave ground;
When pump is lifted to directly over Cargo Oil Pump pedestal, carefully declining makes pump by Cargo Oil pump mount base, and oil pump suction inlet is checked after installation
With oil suction well spacing from installation diagram requirement should be met;
(3)It is follow-up to arrange:Protection cap and the element for being fixedly connected are removed, by the motor shaft of Cargo Oil Pump by bonded
To in propeller boss, oils and fatss should be wiped in a pre-installation, using handss pump to oiling at the suction inlet of Cargo Oil Pump.
It is an advantage of the current invention that:
(1)The oil ship goods tank Cargo Oil Pump installation method of the present invention, mounting process are simple, including in accurate school with
And stable lifting, improve the installation accuracy and installation effectiveness of Cargo Oil Pump;
(2)In oil ship goods tank Cargo Oil Pump installation method of the present invention, it is divided into plank in positioning school and makes and installation, installation
It is in flange, Cargo Oil Pump base stand location, the installation of Cargo Oil pump mount base and Cargo Oil pump mount base school and full in fagging and guide plate, installation school
Six steps of weldering, wherein the center of Cargo Oil pump mount base can be smoothly positioned by flange in plank and school, improve work
Make efficiency, while the installation of Cargo Oil Pump for convenience, is provided with gripper shoe and guide plate in oil cargo tank bottom, hangs in Cargo Oil Pump
There is guide effect during dress;
(3)In oil ship goods tank Cargo Oil Pump installation method of the present invention, lifting prepares before being divided into lifting, lifts and follow-up whole
Three steps of reason, improve safety, stability and the degree of accuracy of lifting.
