The bottom-end of the cylinders is connected to the hull structure in the thruster sea-chest via bushings de

34、livered by Brunvoll.在整個(gè)行程中保持液壓缸的平行度和直線度，對導(dǎo)向架在推進(jìn)器的垂直移動中保持導(dǎo)向作用非常重要。To maintain the guidance of the guiding yoke during the vertical movement of the azimuth, it is of great importance that the parallelism and linearity of the lifting cylinders is maintained during the full stroke.除了控制缸底部，控制不銹鋼軸套和船體結(jié)構(gòu)同樣

35、重要。當(dāng)推進(jìn)器完全伸出到操作位置，起落架應(yīng)落在兩個(gè)液壓缸上，推進(jìn)器的重量完全由接觸面承擔(dān)。在操作位置，導(dǎo)向架，液壓缸導(dǎo)向和軸套以及推進(jìn)器海水箱底部結(jié)構(gòu)之間有間隙，最小間隙為25mm。艙頂法蘭底部和不銹鋼軸套之間的控制尺寸3690 +/- 5。In addition to controlling the horizontal position of the cylinder ends, it is also important to control the vertical position of the stainless steel bushes and the connecting str

When the thruster is fully lowered to the operating position, the lifting yoke shall land on top of the two lifting cylinders and the weight of the thruster shall be carried over this contact only. That is, in the operating position there shall be a clearance (min 25mm) between the guiding y

The vertical stroke is ca. 3430 mm.建議：安裝推進(jìn)器前和后，測試整個(gè)行程。要求船體基線到船塢地面的最下高度尺寸為3430mm。也可以在船塢上挖坑。Recommendation: The full stroke of this mo

39、vement shall be tested both prior to and preferably also after the installation of the thruster unit. This will require a minimum height below the ships base line to the dock floor of min 3430mm. The alternative is to have a pit on the dock floor.12安裝液壓單元液壓單元安裝到一個(gè)合適的基座上。為了推進(jìn)器的初次伸縮，液壓單元應(yīng)安裝。詳見液壓單元圖。開始

41、 HPU for the thruster should be installed and connected in order to ease the initial lowering and retraction of the thruster. See the Brunvoll drawing, “Hydraulic Power Unit”.At an early stage it is common to have a temporary solution when the HPU is connected together with the azimuth unit. Use hos

42、es for this solution:1 hose is connected between “Retraction” on the HPU and the hose bracket on the azimuth (see fig above). The coupling on this bracket is connected to the top of the hydraulic cylinders through pipes.1 hose is connected between “Lower” on the HPU and the two hydraulic cylinders.

43、The two cylinders have a common connection with a T-coupling which is located on the tank top plate.1 hose is connected between the same T-coupling and the hose bracket on the azimuth (pilot pressure).1 hose is connected to the HPU “Lock off” to a T-coupling with two hoses which are mounted to the l

During lowering of the Azimuth Unit for the first time, it is important to check that the locking bracket on lifting yoke does not collide with the locking device.NOTE!

49、Take care when lowering the azimuth unit. If the lowering is carried out without using hydraulic pressure on the lifting cylinders, chain blocks have to be slackened gradually to avoid damaging the unit.
