Shipwreck sand moving tools air/water ??

Re: Shipwreck sand moving tools air/water ??

One thing I forgot to mention. I had to put an external drip oiler on the intake port to
lubricate the vanes in the pump. When the pump is installed in the aircraft an oil line is connected to it to lubricate it when running. When you use the pump by it's self you have to some how lubricate it so it won't burn up. Wish I had that pic to show you what I mean. Just too busy to do anything about it right now. I will try my best.

Get some prices to. Mine was cheap as it was military surplus.

Hang in there alittle bit more. I am checking with a surplus company called "Groban" in Chicago my old home town. There number is 1(800) 621-2405. They don't have any on their website
http://www.groban.com but, the main man "Sid" knows everything and he just left the office for the day. This is the place I got mine from many years ago. The prices of that place you looked at were for aviation inspected replacements thus the HIGH price. The ones they showed on their catalog pages are close to the one I have. Some (the cheaper ones) are smaller. Just remember that you have to get an adapter for the shaft as these units mounted on the timing gear train portion of the engines. Groban had adapters already made up for gasoline engine shafts (mine is 3/4-inch) when I bought mine. I think I only paid $20.00 for the whole package. Note: That shaft you see coming out of the pump is somewhat flexible so you have to make a stationary mounting bracket next to the driving engine for the pump to keep it lined up. Also don't forget about what I said regarding lubrication.

I will check with you later. You might try looking for surplus places in California as there are alot of them there.

10-4 Dinky....how'd you guess I was running out of patience?! Can't believe no one makes/sells these things.....maybe I should?!!!!

Well I have some bad news and some good news but you have to be patient.

First the bad news - The adapter for the vacuum is not available. I have found out that the spline used on the pumps is a standard SAE size.

Now the good news - They have some pumps in stock but I don't have the part number as of yet. I will try to get it in a day or two so you can order one. Best part the price $20.00 each. You have to
promise me not to buy all of them up. I don't know how many of them they have in stock. They have two sizes so I will have to find out which one is the one we need.

So, HANG IN THERE

No new developments as of today. I will keep you posted. Yes a gasoline powered air
compressor will work but, I am trying to save your back by you having a light portable
air compressor. You might want to try your compressor out in a small (unfrozed) lake before packing
it one mile into the woods.

I will keep you posted by sending you a PM.

I am working on it. Just didn't get a confirmation on availability today. I hope to get one by the end of the week.

Take care

I only had 10 messages in the PM file. Must be the maximum. Took out seven please try again.

Re: Shipwreck sand moving tools air/water ??

Sucking mud is my best subject. I have been doing it for 50 years. I will agree with you that the airlift I mentioned in my previous post was quite primitive. However, IT WORKS.

As to your reference to diving to 60-feet and coming up too quickly, It isn't the rate of ascent which gives you the bends it's the time you have spent AT 60-feet (breathing OXYGEN and NITROGEN) at high pressure and absorbing the NITROGEN into your blood. The longer you spend at 60-feet the MORE NITROGEN you absorb. NITROGEN bubbles form in your blood stream when the ambient pressure on your body is reduced when ascending. HAVE YOU EVER BEEN IN A RECOMPRESSION CHAMBER? Have you ever operated one? Do you know how they work? Do you know that the air we inhale very breath is poisinous at 600 feet. You go FIGURE

FWIW Do some reading on Surface Decompression Using Oxygen and write me back.

have a nice day

I bow to your age. I am 69 and STILL diving.

P.S. I did get to dive in Korea even though there was a war going on. It was a nice place in a little town called Inchon. Best part is we had a 29-foot tide change, more like surf diving and I have also worked in the surf which is not a nice place to be either.
 

Re: Shipwreck sand moving tools air/water ??

Hi use a 3 inch fire pump with minimal 5-9 Hp honda gas engine - inverted into a four inch pipe creating a venturi , elbow easy and cost efficient or a 3 inch trash pump pumping water downwards into an elbow will suffice with discharge into a fishpot cage made from chicken wire. minimal out put of 90 psi
this works well or look bigger at a company called wesee konstruksie out of Namibia or Russia.
good luck

Re: Shipwreck sand moving tools air/water ??

Ya, a water pump/venturi works fine providing you have enough flow to keep the heavy stuff moving.. But they aint light.. We usually just used a firepump for digging holes and moving sand.. They work pretty good for pushing a sling under something you want to lift out of the mud or sand.. but air does a much better job of lifiting stuff.. The design Dinky posted is simple, and effective.. In my experiance, elaborate only adds problems and problems begat headaches.. The KISS principal is always best...
 

Re: Shipwreck sand moving tools air/water ??

Hey guys, is there a way to move the sand horizontally? I'm working on a underwater tunnel... the tunnel was covered with sand. the mouth is just about 1 meter diameter. Actually the water is just about 7 feet deep.

Re: Shipwreck sand moving tools air/water ??

hmmmm... I think using airlift would be difficult.. how about blasting the sand out, is it possible? underwater? thanks for your help. :)

Re: Shipwreck sand moving tools air/water ??

I don't know if this will help but here goes:

I once had a job to remove a 30-year collection of sand from street run-off. The sand was in a box culvert below the city street. The level of sand was about 1-foot from the ceiling. I used a 6-inch submersible hydraulic driven water pump and alot of 6-inch PVC drain pipe. I devised a method where I would put a small extension on the large intake pipe and clean until I got no more sand. Then I would install another small piece of pipe and repeat the procedure. The output of the pump was placed into a barge tied to the outlet at the seawall. The culvert was 1500-feet long and I had the hydraulic pump located at the 400-foot mark for the entire job. 9000 cubic yards of sand and debris were removed. I never checked the discharge for any treasure. Guess I will have to go culvert diving again. I did loose my Rolex watch, the pump suction broke the band and the watch went into the brage somewhere. Never did find it.

Using the airlift in your application I would suggest that you place the vertical airlift pipe in the deepest location even if you have to deepen the location of the airlift. Put a sweeping elbow on the inlet to the airlift and use any pipe or hose that will not colapse for your horizontal runs. All pipe joints should be as air/water tight as possible to get the most suction at the inlet.

Hope this helps. HH

Re: Shipwreck sand moving tools air/water ??

Thanks guys for the suggestions.... I've check the place this morning. sad to say that my info was wrong. Now, the actual depth of the water is just around 4'6" to 5'. This place is in a river. And the place is tight. The entrance is surrounded by two big rocks. only one man would fit. the working space is just about 1.5 x 1 meter. Its like three rocks been put together and the entrance is in the middle. The? tunnel goes through one of the rock. And that rock is big as a house. We were told that this is the only entrance. I believe the tunnel is just 2 meters long, the most. I think I only have to remove about 2-3 cubic meters of sand.

My problems:
1. If I have to remove the sand, I have to do it fast. maybe 1 hr. to 2 hr. max. the place is in the middle of the city, :) and almost everybody around it knows that there's a treasure there. there are many attempts to find this place. Twice somebody use an explosive to break the rock, but the wrong rock. So, if I stay long in the place maybe I'll be in the TV.? No problems with the law here, justthat I don't want to be in the National news.

2. I don't have an hydraulic pump and I think nobody here has one. I only have a 2" water pump and a air compressor.
3. I can not make trial and error practice run at the place.
4. the sand is mix with mud.

can I use blasting it with water then removing it by an airlift?
if I have to make an airlift, it would be just about 4 ft long right? will it work?
up to how long can I make my horizontal runs? 2 ft - 3ft or longer?

Any suggestions? :)
 

Re: Shipwreck sand moving tools air/water ??

OK, here is what I would do. Get yourself enough discharge hose for the 2-inch water pump and convert the threads on the outlet (the end the water comes out) to standard pipe threads. Should be 2-inch NPT. Connect a 2-inch to 1-1/2 or 1-inch reducer to this pipe. Put on a pipe nipple that is long enough to reach inside the hole you have to clean out. At the end of this pipe put a pipe elbow and a short nipple. Then put on a pipe "T" into this "T" put two short nipples and two 3/4-inch reducer coulpings. Then put two short 3/4-inch nipples. What you should end up with is a long pipe with a "T" on the end with it's 3/4-inch pipe nipples facing forward and backward. The nipple facing forward is the jetting nozzle and the one facing back is the blowing nozzle. The forward one does the digging and the back one blows the dirt out the hole right at you.

I hope that this is clear.
