In order to solve the above technical problems, the present invention also provides a kind of installation method of hydraulic jet propulsion system, including it is following
Step:
Step 1 determines center line of shafting, the reference line as equipment location and installation.Wherein center line of shafting is according to rib position
Data find the determination of shafting head and the tail basic point away from midship data and away from baseline altitude information；
In addition, before determining center line of shafting, it is necessary to assure main hull closes up greatly welding equipment and finishes after cabin antetheca, fire
Work correction work terminates, and hull is freely placed on and is moved on ship trolley, and all hull rigidity supports in shafting region are changed to wood
Support, large scale equipment install the ballast of equivalent weight additional in place or in corresponding site into cabin, finally determine in shafting by drawing data
Heart line bow stern reference point location, and make a record, determine center line of shafting.
Step 2 carries out the installation seat plate 3 of hydraulic jet propulsion system by first time irradiation on the basis of center line of shafting
Location and installation.Center line of shafting bow stern datum mark is first found when implementation, and makes wire pulling rack, wire pulling rack installation with angle steel
Two light targets, mark upper and lower position line on the installation seat plate of hydraulic jet propulsion system, then in the fixed light in the center of installation seat plate 3
Target is adjusted to same bow stern datum mark and is overlapped with micr-alignment telescope, is symmetrically welded after spot welding positioning.
Step 3 determines the installation seat plate 3 of hydraulic jet propulsion system by second of irradiation on the basis of center line of shafting
Machining benchmark bore hole circle and check reference inspection circle after welding.After installation seat plate 3 welds, in the inner hole of installation seat plate 3
Irradiation light target is installed, with micr-alignment telescope, same bow stern datum mark is adjusted to and is overlapped, drawn according to the light target position of irradiation adjustment
Bore hole is round out, checks circle and stamps foreign punch mark.
Step 4 is carried out the installation of live Boring machine by bore hole circle and on the basis of checking circle, carries out the installation of hydraulic jet propulsion
The plane machining of the end face of seat board 3, plane and center line of shafting verticality after processing meet inclination of the radius relative to axis
≤ 0.05 ° (0.8mm/m), to guarantee the end face of installation seat plate 3 and the verticality of center line of shafting.
Step 5 determines the installation of the shell 4 of hydraulic jet propulsion system by third time irradiation on the basis of center line of shafting
Position, and template is made by 4 big end flange screw of shell, it positions and drills on installation seat plate 3, by shell 4 and pacified with bolt
Seat board 3 is filled to connect.Light target first is loaded onto the big end of shell 4 when installation, is aligned light target center with center line of shafting by irradiation.
Template is made by 4 big end flange screw of shell, positions and drills on installation seat plate 3, with bolt by shell 4 and installation seat plate 3
Connection, installation contact surface should be uniformly coated with sealant and carry out compression sealing when connection, glue thickness will uniformly, at the top of dormant bolt and
With applying, the filling of Sikaflex sealant is full to play sealing and insulating effect for bottom.
Step 6, using the small end flanges of the shell 4 after installing as reference data, according to the elbow 9 of hydraulic jet propulsion system
Dimension data cut off surplus on runner 5, carry out the installation of elbow 9.9 both ends of elbow, two positions up and down are first measured when installation respectively
Then the respective distances set check the distance that runner 5 arrives 4 small end of shell, cut off extra 5 size of runner, then carry out water spray and push away
Into the connection installation of the elbow 9 of device.
Wherein, to guarantee that inner surface is aligned deviation no more than 1 when elbow 9 being aligned with shell 4.According to the spiral shell of shell flange
Hole pulls bolt hole on elbow flange, after removing elbow 9, the drill bolt hole on GRP elbow.Again GRP elbow is reinstalled into shell
Body, guarantees alignment, and alignment deviation is not more than 1.4 screws, washer, nuts are installed, elbow is fixed on shell 4.By runner
Flange is placed on entrance and spot welding, pulls bolt hole on elbow flange according to runner flange bolt hole, elbow 9 is removed, curved
Bolt hole is drilled on first 9.By runner flange welding on the entrance of runner 5, sealant is smeared on runner flange, smoothes out flange
Surface.By elbow 9 again mounted between flow channel entry point and shell 4, notice that elbow 9 has between flow channel entry point and shell flange
O-ring seal installs the fastener at 9 both ends of elbow.
Impeller shaft 6, diffuser 2 and transfer 1 are hung to installation site, and connect with shell 4 by lifting by step 7
Connect fixation.It is lifted by way of opening up hoisting hole when lifting.First by diffuser 2 lock shaft when installing impeller shaft
Device is removed, and then spreads watertight grease at 6 rear end spline of impeller shaft, and impeller shaft 6 is inserted into diffuser 2 at shaft coupling, is returned
Fill axle jack.
Step 8 measures and adjusts the gap between the blade and shell 4 of the impeller 7 of hydraulic jet propulsion system, guarantees blade
The distance between shell 4 is met the requirements, and is measured when measurement by clearance gauge, impeller is rotated clockwise manually first, at impeller 7
When top, the gap between impeller 7 and shell 4 is measured, measures and records endpoint and intermediate point before and after the blade of each impeller 7
Gap at three, it is desirable that the distance between blade and shell 4 of impeller 7 are met the requirements.
Step 9 measures and records between shaft coupling and impeller 74 points of gap up and down, tightens after meeting the requirements
Between bearing 8 foundation bolt.Wherein, 4 points of deviation needs consistent up and down, and deviation range is ± 0.15mm, and when measurement is logical
Clearance gauge is crossed to measure.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
