YSLD 6PN-30 type river selfpropelled jet suction dredger equipment list
1.sand dredger/boat:length:7.7m,width:2.8m,height:1m,for easy transportation,we design it into four floating bodys:split type dredger with moving engine.(main floating body length:2.7m,width:2m,the bottom plate thickness:8mm,the other plates:4mm.the rear floating body length:2.7m,width:0.8m,the steel plates are all 4mm in thickness,all sides are closed.two pcs front floating bodys:length 5m,width 0.8m,all sides are also closed.the skeleton in the floating body are all made of 50*50 angel steels,dredger weight:3.5t or so
K.manual operation windlass(for lifting the sand suction pipe)1set 250usd
L.net with frame 1piece 30usd
M.remark:the all equipments weight are 5t or so,working weight 5.3t or so(including the sand water in the pipe when pumping sand),the draught:0.35m or so,need to adjust the draught to 0.55-0.6m when working,then no need to add water into the pump and no need vacuum pump,because the water level is higher than the pump inlet,the water will flow into the pump automatically.in order to solve following problem:pump water into the closed floating body to make the dredger draught to 0.55-0.6m or pump water out from the closed floating body to make the dredger float up,need a small submersible pump,220v,single phase,flow 15m3/h,head:20m,2.2kw,price:160usd
N.Movable engine with 32HP diesel engine:1700usd
Dredger total amount:25137usd
Total amount based on FOB qingdao:26602USD
Shipped in a 40' container
Lead time:15 days after payment
Payment term:100% T/T to our company account before shipment
Abrasion resistant mud sand pump parts instruction of the dredger,
1. Support frame:main part for supporting flow parts,connect with bearing plates on the two sides to form bearing assembly.
2. Pump casing:connect with support frame by 6 bolts,can rotate in 60°gap according to needs,impeller,protecting plate,pump cover installed inside,material is abrasion resistant,the impeller,pump casing and pump cover of this pump are same as 6PNL-30 vertical mud sand pump.
3. Split type pump casing with long pump cover(flat pump cover and long pump cover).one body pump casing is available also.
4. Shaft seal box:installed outside of protecting plate,seal assembly installed in it,it joints shaft sleeve,lubricating it with grease through grease fitting to prolong lifetime.
5. Shaft sleeve:installed at the back of impeller,can compress tightly by impeller rotation.
6. Water retaining plate:installed in front of the front bearing gland,compressed with a screw so that it can rotate with pump shaft in same speed and direction,and form labyrinth seal with front bearing gland to prevent the liquid spilling from shaft sleeve from damaging bearing.
7. Support frame oil injection hole:one oil fitting on each side of support frame for lubricating the bearing.
8. Pump rotation direction is clockwise judge from motor side,counter clockwise is prohibited.
