gearbox gold divers grabber lake dredge pump

gearbox gold divers  grabber lake dredge pump

high quality lake dredge pump can pump big strong abrasive material which cant be done by a      common lake dredge pump.Widely used in dredge boat,river,mining and metal smelting and so on;

1. Clear water injection pipe for seal:water injection pressure should be above 1kg than pump working pressure,which will be a high pressure clear water area to seal between stuffing box(packing room) and impeller.

2. stuffing box:named packing room,first install stuffing ring in packing room,then put into several circles of packing

3. Packing gland:installed on shaft sleeve outside and stuffing box entrance,compress the packing to suitable position with two pieces bolts through pakcing gland.

4. Shaft sleeve:abrasion resistant high chrome alloy material,installed outside of the pump shaft and the inside of stuffing box,which make friction between shaft sleeve outside and packing,the clear water seal will prolong shaft sleeve lifetime.

5. Disassembled ring:there are three parts for it,installed between shaft sleeve and water retaining plate,please remove the three bolts on it when dismantle pump,then remove the three parts with hammer in order to dismantle the impeller;

6. Water retaining plate:installed between front bearing gland and disassembled ring,its excircle and bearing gland forms labyrinth joint which will prevent the slurry spilling from stuffing box into the bearing box.

7. Oil injection hole:inject lubricating oil into bearing box through it.

8. Oil level window:please add oil level between above middle line and under 20mm when make sure pump base parrallel to the ground.

9. Bearing box:control the back bearing on frame support with back bearing gland,can adjust the impeller gap with the 8 pieces bolts on bearing box.
