The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Between the indoor set of the marine air conditioner in the present invention and off-premises station, adopting axial cross section is that the thin-walled tube of rectangle connects, as everyone knows, the lower stability of center of gravity of boats and ships is better, but the airduct overwhelming majority of air-conditioning is all arranged in the superstructure of boats and ships, in order to reduce boats and ships center of gravity, guarantee safety of ship, the airduct in the present invention adopts zincing steel sheet or the general steel plate that thickness is 0.75-1.2mm to be made, therefore claim again thin-wall rectangular air conditioning wind pipe.In order to guarantee the intensity of installing and using of thin-wall rectangular air conditioning wind pipe, avoid airduct in use to occur the situations such as vibrations, in installation process or before installing, need the intensity of thin-walled airduct to strengthen.The mode of strengthening has two kinds conventionally: as shown in Figure 1: indent is strengthened, support reinforcing shown in reinforced rib 2 and Fig. 2 is set on the sidewall of airduct 1, in airduct 1 inside, set up brace panel 3, by 3 pairs of relative sidewalls of airduct of brace panel, support, to strengthen its intensity.Above-mentioned two kinds of methods are simple to operate, and can greatly increase the intensity of airduct, thereby further guarantee the whole structure that airduct is installed and used.
Airduct is set with several mounting flanges conventionally outside it, and the mode that is then fixed on the support on deck by mounting flange is fixed on is installed airduct above deck.Conventional form of flanges has three kinds: angle steel flange, grooved flange and thin plate compacting flange.As shown in Figure 3, what thin-walled airduct was the most frequently used is angle steel flange 9, and angle steel flange 9 is sleeved on outside airduct 9, then by bolt 8 and support, fixes.Shown in Fig. 6 is grooved flange 13, grooved flange 13 is with respect to angle steel flange 9, there is higher installation reliability, and be particularly suitable for for using in this short space of cabin, because because the distance of the between decks vertical layout air conditioning wind pipe of boats and ships just only has 140-200mm, so airduct height has to be compressed to 125-150mm, as: 1200X125, 900X125, 700X150 etc., when this type of airduct is installed, if flange adopts bolt to fix, due to narrow space, the bolt at top at all cannot be fastening, and grooved flange 13 connects without bolt, only grooved flange 13 need be inserted on airduct, again with sealant sealing, easy construction, fixation.Shown in Fig. 7 is thin plate compacting flange 14, owing to adopting angle steel flange 9 to rivet the tube wall of airduct with as the angle steel of flange with rivet, then by angle steel flange, airduct is arranged on erecting frame.This mounting means, the phenomenons such as rear easily generation is leaked out, vibrations are installed, and airduct very easily corrodes in riveted joint position.Therefore, for can use fastener 15 to carry out 1 of fastening airduct from both sides, can adopt thin plate compacting flange 15 to mount.Thin plate compacting flange 15 has following advantages: 1), reduce construction working amount, 2), flange and airduct one can not produce and leak out, 3), the whole galvanized anticorrosive erosion of airduct performance is better, 4), the whole press strengthi of airduct is better, has good shockproof properties.
The installation of airduct
Because the indoor and outdoor machine of air-conditioning is distant, the cross section of airduct is larger again, so conventionally by air pipe subsection processing, and then according to the concrete distance of indoor and outdoor machine, select some sections of airducts to connect while using.In addition, due to the lower boats and ships of deck height, in order to guarantee the requirement of 2030mm floor height, in order to guarantee setting accuracy, airduct should, from one end, link together some sections of airducts in order, above deck, such mounting means can be avoided modification unnecessary in installation process and do over again in lifting.
According to characteristics such as airduct self sizes, choose after corresponding flange, can start airduct to install.Concrete steps are as follows:
Mounting bracket
The airduct of square-section is different with spiral duct, and due to the cross section of airduct, to be that flat rectangular (500～1200X125mm) is difficult to fixing, so, must can be fixed by the cooperation of support and flange.So first support, as the connecting element between the fixtures such as airduct and deck, should be fixed on deck or other fixtures by modes such as welding.The support that airduct is conventional has three kinds: angle bar frame, flat support and shackle bracket, and Applicable scope and the mounting means of these three kinds of supports are specific as follows:
1, the range of use of angle bar frame and installation: the general and angle steel flange of angle bar frame supports the use, and by bolt, angle bar frame is fixedly connected with angle steel flange.In order to facilitate airduct installation and position to be adjusted on angle bar frame, pride is provided with the mounting hole of several oval shapes along its length, by adjusting the bolt of fixed angles steel flange and angle bar frame in the position of the mounting hole centre of oval shape, setting height(from bottom) to airduct is finely tuned, and eliminates site operation error.As shown in Figure 3, during installation, the centre coordinate of rectangle air conditioning wind pipe 1 of first take is benchmark, backing plate 4 is welded on the desired location on deck 5, has avoided deck 5 to polish, and on its surperficial coating layer, can not cause very large impact.Then, angle bar frame 6 with oval hole is welded on backing plate 4, and suitably select the length of angle bar frame used 6, to guarantee that the lowest part of angle bar frame 6 is higher than the lower surface of airduct 1, when like this airduct 1 is regulated, can not make angle bar frame 6 protrude from airduct 1, guarantee the reasonable utilization of boats and ships vertical space.For guaranteeing the stability of airduct 1, angle bar frame 6 and matching used angle steel flange with it are at least set at the two ends of every section of airduct 1, and the distance between the angle bar frame 6 of every section of airduct 1 both sides should be slightly larger than the width of airduct 1, and guarantee that two distances between respective corners steel bracket 6 and the error between airduct 1 width are within 1mm; Next, use bolt that the angle steel flange 9 being enclosed within outside airduct 1 is fixed on angle bar frame 6, complete the fixing of airduct 1.Firm in order to guarantee that airduct 1 is installed, can on the bolt that connects airduct 1 and angle bar frame 6, add spring washer 8 locking.
2, flat support range of use and installation:.In order to ensure the refrigeration of a/c system, some boats and ships, for example: marine sciences integrated survey ship, need to adopt section width to be greater than the airduct 1 of 500mm, for example, sectional dimension is the airduct of 600X125,800X125.Use the airduct in this width range also to guarantee boats and ships floor height when guaranteeing refrigeration.Above-mentioned angle bar frame 6 can only be for being used the airduct of angle steel flange and the airduct of width≤500mm 1.Adopt grooved flange or larger-size airduct 1 should adopt when mounted flat support.As shown in Figure 4, first, determine the height H between the upper surface of airduct 1 and the lower surface on deck 5 and install with the distance K between bolt, wherein, the insulation of H=deck height-deck covering thickness-top ceiling thickness-floor height-airduct, the maximum outside diameter+40mm of K=nut.Then, according to the size field fabrication of airduct 1 and flat support 10 of installation, flat support 10 is arranged on the desired location on deck 5.The inside dimension Le+Lf of flat support 10, than the smaller 0.5-1mm of the width of airduct 1, guarantees that flat support 10 can be fixed airduct.
3, the range of use of shackle bracket and installation:: very large for size: width is greater than airduct or the plenum chamber of 800mm, for example: axial cross section is of a size of 1800X1200mm, adopt shackle bracket can obtain good installation effect.Each section of general large-scale airduct all needs 4-8 shackle bracket.When shackle bracket is installed, first press the design coordinate of airduct 1, one of them shackle bracket is fixed on the desired location on deck, then according to wide, the long installation site of determining other shackle bracket in this section of airduct 1, and then airduct is fixed on shackle bracket.Be specially, as shown in Figure 5, shackle bracket comprises that hanger 11 and 12, two hangers of lower hanger are L shaped plate, and the straight flange perpendicular to deck 5 is fixed on deck 5 by it wherein to go up hanger 11.During installation, first lower hanger 12 is welded on airduct 1.Then, upper hanger 11 is fixed on deck 5.With bolt, upper and lower two hangers 11,12 are fixed together again.In addition, can between upper and lower hanger 11,12, also can install rubber washer additional, be used for shockproof and noise-proofing.Finally, airduct 1 is lifted on shackle bracket.Shackle bracket is simple in structure, easy for installation, the very large air conditioning wind pipe 1 of size firmly can be fixed on deck 5.Meanwhile, also because its volume is little, save boats and ships vertical space, realized the theory of the high floor height of ship design of between decks height.
The insulation of airduct is heat insulation
The quality of the heat insulation quality of insulation of airduct directly affects refrigeration, the heating effect of whole a/c system, so very important to the installation of airduct insulating barrier.What in the present invention, airduct adopted is external insulation mode, at airduct outer cladding insulating barrier.This insulation mode is easy to suffer the destruction of extraneous external force.So the installation of air conditioning wind pipe insulating barrier must guarantee firmly, reliable.Concrete installation method is as follows: except air duct flange junction, other local form of first wrapping up airduct with insulating material is in airduct arranged outside insulated thermal insulating layer, if communication cabin component is not set between some sections of air conditioning wind pipes, can first these several sections of airducts be linked together, whole installation insulating barrier.So, reduced work capacity, also construction quality and construction period have been guaranteed, 1), on airduct surface, be coated with one deck glue the step of wrapping insulating material is:, and guarantee to apply evenly 2), press the insulating material of airduct size shearing corresponding size, then from the right angle of airduct, start to stick insulating material, stick in process and smooth from top to bottom, and guarantee not leave any gap between insulating material and airduct, to avoid in airduct use procedure, at airduct outside face, produce condensed water.Insulating material need be stayed the joint of insulating material the place, right angle of airduct when coated, and by the interlaced setpoint distance in the two ends of joint, be generally 10mm, to guarantee the quality of insulating barrier, 3), the insulating barrier outside that is positioned at the place, two ends of every section of airduct also needs coated glass wool cloth, to prevent that insulating barrier from playing glue.When insulating material is coated, should guarantee that insulating material is applied to flange the inside, to guarantee that airduct really inscribes air-tightness.In addition, it should also be noted that airduct is used monoblock zincing steel sheet to make conventionally, and the staggered 10mm in junction, stick with glue and use again rivet.During coated insulation layer, also need assurance insulation staggered place and airduct junction to stagger.
Lifting airduct
The airduct being provided with after insulating barrier is passed through to the flange on it, according to the mounting means of the above-mentioned various flanges support corresponding with it, be lifted on support.
The sealing of flange and insulate heat insulation
Sealing step between the flange of airduct is: first with rubber plate, cut a gasket seal identical with flange size, the oblique angle of 45 degree is cut in pad staggered place, then with glue, pad is sticked on flange, afterwards on bolt with flange, add shoot pad locking, finally in flange surrounding, be coated with a circle glue, thereby the reliability that guarantees flange seal, re-uses insulating material flange is coated.
The insulation of support is heat insulation
Use insulating material that support is coated, its coated scope is for to extend upward setpoint distance by flange connections, to avoid producing condensed water.
The installation of communication cabin component
Communication cabin component needs and hull bulkhead weld together as the main support part of hull bulkhead.Communication cabin component is that metallic material is made, and its coefficient of thermal conductivity is larger, as Rig up error be easy to make to produce inside and outside airduct heat transmit and make to carry in airduct cold/hot blast produces a large amount of thermal losss in course of conveying.Communication cabin component can be divided into bulkhead communication cabin component and T-shaped material communication cabin component.
The installation of bulkhead communication cabin component: if airduct need, through bulkhead, add communication cabin component to strengthen hull bulkhead intensity on the bulkhead that need pass at it.As shown in Figure 8, owing to being all provided with the vertical stiffener of mono-grade of 500-600mm on bulkhead 16, and the width of communication cabin component 17 is generally between 500-1200mm, so can wear disconnected one or two stiffeners when communication cabin component passes bulkhead 16, in order to guarantee Hull Strength, the surrounding of communication cabin component 17 need be carried out suitable reinforcement.1), perforate the concrete installation steps of communication cabin component 17 are as follows:: centered by the centre coordinate of airduct 1, and perforate on bulkhead 16, each length of side of institute's perforate all needs than the long 10mm of the length of side of the corresponding edge of the flange of air conditioning wind pipe 1; 2), strengthen crossing cabin place, in the position of airduct each 200mm of both sides Shang Xia 1, add two horizontal stiffeners, so the vertical stiffener between latter two horizontal stiffener disconnects, 3), the crossing cabin web of airduct 1 is welded on bulkhead 6,4), on the inside and outside two sides of communication cabin component 17, be coated with the finish paint identical with bulkhead, 5), that the communication cabin component 17 of airduct 1 is carried out to partiting thermal insulation is coated, insulating barrier, on bulkhead, extends 450mm to surrounding.The vertical coordinate position that must coordinate connected airduct 1 when communication cabin component 17 is installed, guarantees that the axis of both sides airduct 1 is in same level, avoids secondary to revise.
2, the installation of T-shaped material communication cabin component.As shown in Figure 9, because particulars of ship has clear and definite requirement to perforate size and position on T-shaped material 18, and the size of rectangle air conditioning wind pipe 1 is larger, can not directly through T-shaped material 18, arrange.The present invention adopts breakaway-element communication cabin component for this reason, airduct 1 disconnects at T-shaped material 18 places, on T-shaped material 18, open than the hole of the little 10mm of airduct internal diameter, when guaranteeing draught area, also guarantee that communication cabin component can be by the relevant regulations in steel seagoing vessel classification rules 2009 through T-shaped material 18 like this.The concrete installation method of T-shaped material communication cabin component is as follows: 1), on T-shaped material 8 by setting coordinate perforate 19, four jiaos of hole 19 fall the chamfering of R30-R100, avoid stress to concentrate; 2), two sections of airduct 1 are welded in T-shaped material 18 both sides respectively, airduct 1 welding edge chamfering, guarantees welding quality; 3), in communication cabin component, outside is coated with the finish paint identical with bulkhead; 4), communication cabin component is carried out to insulating wrapped; Insulating barrier 20 extends 450mm on T-shaped material 18 and bulkhead 16.During installation, guarantee to leave between the flange of communication cabin component and bulkhead the space of 70mm, to facilitate binding bolt.
The installation of attached wall airduct
Because the boats and ships space of between decks height is very little, a lot of local rectangle air conditioning wind pipes also cannot adopt, and therefore, the present invention adopts attached wall air conditioning wind pipe to solve the problems referred to above.What attached wall airduct adopted is that interior insulation mode insulate, and namely insulating barrier is arranged on to attached wall airduct inner.In the situation that not taking up room, guarantee the normal operation of a/c system.Concrete installation steps are as follows: 1), attached wall airduct is welded on the desired location of bulkhead by setting coordinate, butt welded seam carries out fairing processing; 2), in attached wall airduct inside face welding, touch nail; 3), on attached wall airduct, open auxiliary hole, auxiliary hole connects with stainless steel bolt, guarantees that workmen enters smoothly, and maintenance after convenient; 4), deck, bulkhead and attached wall airduct are polished, primed; 5), at attached wall airduct inside face, rock wool insulating material is installed; 6), on insulating material, lay one deck masking foil, and fixing with touching nail, avoid rock wool to damage human body; 7), at auxiliary hole inside face, lay rock wool and masking foil; 8), installing technological hole, and at its outside face coated one deck insulating material again, guarantee attached wall airduct reliability service.If the height of attached wall airduct reach 2000mm above can install within it vertical ladder convenient after maintenance, in the installation process of attached wall airduct, must guarantee the construction quality of the seam of insulation to prevent that this place from producing cold and hot transmission, thereby extend what insulate, be to use the life-span.
