Why sand dredge pumps don't suction sand and what are the soultions? - Reasons & Solutions
-
Reason - there is air in the sand dredge pump and suction rubber hose to dredge pump
-
Solution- injet water into sand dredg pump and suction rubber hose from the connect between pump and hose or pipe.
-
Reason - The total suction height is too large for sand dredge pump comparing with suction ability and pump capacity.
-
Solution - reduce the sand dredge pump suction depth and use a smaller size of suction rubber hose.
-
Reason - The pipeline which is working together with sand dredge pump is air leaked, it often happens between the sand dredge pump and suction hose.
-
Solution - fix the air leak point or change a new rubber hose.
-
Reason - The working head loss which is caused by tranfer distance plus vertical height is larger than sand dredge pump working pressure.
-
Solution - increase sand dredge pump rotating speed by a higher speed of diesel engine.
-
Reason - The shaft seal is not operated with water injet which could cause air leak from shaft seal part.
-
Solution - Injet water to shaft seal and fastern the seal bolts.
-
Reason - Sand dredge pump is blocked by large particle and the suction rubber hose is blocked by sludge.
-
Solutin - Clean the sand dredge pump and the rubber hose.
-
-
-
Reason - Sand dredge pump is in wrong rotating direction. Solution - Correct the rotating direction into right way.
-
Reasonb - Broken sand dredge pump impeller. Solution - Change a new sand dredge pump impeller.
Why sand dredge pumps don't suction sand and what are the soultions? - Conclusion
In this article, China Do Pump is a sand dredge pump solution provider by sharing why sand dredge pumps do not suction sand and what are the solutions, in general, check whether there is air leak in pipe, hose which are from suction side, double check the suction depth is too large and total working head is larger than pump working head, and/or pump is in wrong rotating direction and a broken sand dredge pump impeller can also cause no suction sand from the pump.
