In order to achieve these principles, we are not afraid of any challenges and challenge ourselves in pursuit of our goals. Return a high rate of interest to our customer. Our company name ACIR originated from the following principles: Note: Dredge swivel bends are the non-standard equipment, we can provide it according to your special requests.Ģ)Certificate: CCS, ABS, BV, GL, LR, DNV, RINA,NK, RS, EC, etc.Ĥ)Delivery Terms: EX WORKS, FOB, CNF, CIF The swivel bends adjust easily with a large rotation angle. Rotation angle is 120 degree.Ĥ.Made from high-strength, hard-wearing steel.ĥ.Good performance bearing, protected by steel cover.ĭredge swivel bends provide flexibility between the cutter suction dredger and the floating discharge pipelines. The dredge swivel bends can be worked under the working pressure 10 bar to 30 bar, the available pipe diameters in the range of 300mm to 1200mm. By splitting your actually off-setting the jet column and introducing considerable turbulence into your suction nozzle which will reduce effeciencey.Dredge swivel bend is the parts of the cutter suction dredger components, installed on the CSD stern as the CSD discharge device. This helps increase efficiency and ensures the high pressure jet of water remains in the thalweg of the water column. Reason being is you want your jet of water to enter right bang in the middle of the suction nozzle. I just don’t see the logic of that on a suction nozzle setup. I wouldn’t be going down the route of splitting the jets into 2. The hp400 has a far bit of volume behind her but lacks pressure at higher rpm. I’d be starting with a 1 inch and playing round either side of that to hone in on the sweet spot. With that pump combo if you can design it so you can interchange out the reducers to get you the most sux would be the best bet. I run 15hp pumps on my honda gx200 motors piece of piss and also managed to make them lighter with a lot of billet parts. 88 and straight away you have an 8hp motor ! I’m assuming your running a Honda gx200 not a clone gx200? Start with removing restrictive exhuast and inlet and replace with free flowing velocity stack and go cart exhuast once you do that replace main jet to a. The 6.5hp do struggle a bit if you are running a 2 piston compressor like a Ghast or PCA with that pump especially if your at altitude and/or its a hot day but there’s lots of things you can do to ekk out a bit more performance out of them. A well designed jet should always be built around the pump that is powering it and is probably the second most important thing on a dredge behind the pump.Ī 6.5hp should be fine with a proline hp400 pump. A conical reducing jet allows the water entering the suction nozzle to have the required velocity or pressure to induce a suction effect. This formula assumes you have made a reducing conical jet. Generally the formula is you divide your suction hose diameter by 4.5- 5,25 to get the “jet size” this would be dependent on running intake pressure at around 30-35 psi and having a pump capable of moving minimum around 2200 liters per minute. Also you will need to stipulate what the design of the reducer is within the jet? To answer your question and perhaps steer you in the right direction you need to provide some more info such as the pump output and hp as well as the pump outlet diameter size. Im guessing you want a suction nozzle as you will be using this out of the water? This is just plain impractical! a 6 inch dredge hose is a monster to handle on a good day bloody hell having to man handle it via a suction nozzle setup! There is a reason none of the major dredge manufactures made a 6 inch suction nozzle and this is why. I’ve never heard of this type of setup on a suction nozzle and can tell you you will need 3 hoses to wrestle with 1 being the suction nozzle and x 2 high pressure lines to the jets. You talk about a suction nozzle setup ( you say you dont want a jet log) with a twin log setup?. The pump is probably the most important design consideration on a dredge! By far the best solution for this is a centrifugal pump with a closed impeller design. The key to a good performing dredge is having a good dredge pump that has a mixture of pressure and volume. Pressure and volume are important no matter what dredge you have!.
