Mud pump technology type
Mud pump by process type points are: direct platoon to send, digging, relay lining (suction) luck blowing, tide construction technology, salt mud filling bag construction technology, underwater sand suction technology, etc.
1, direct platoon to send - mud pump mud directly to sent to the designated location.
2 - when the mud pump, relay lining from far away, beyond the mud pump efficiency of straight line limit, adopt the method to improve the efficacy of the relay to a relay relay, two or more, the more contact, the farther, don't need high pressure water pump, with the pool of by, dock, station and so on a variety of methods, pool is first selection, more than a pool pump; Also available high-power pump used as a relay, high efficiency and low cost.
3, dig (suction) blow - if soilless sand source or sources, construction area is dug from the distance (suction) take transport to ShiGongDian again by mud pump unit delivery to their appointed places land reclamation or irrigation bag.
4, tide construction technology (river) - sea beach mud pump construction affected by the flood, mud pump is anchored in the beach face, high tide, floating to continue the construction after the ebb, the land reclamation works around the more use of the process. More due to excavation of earthwork digging holes in the water, the greater the next tide when pumping the longer, shorter work time, so the mud pump and more frequent, usually two or three will have to move a tide, a honeycomb excavation area, has great influence on construction safety, construction efficiency.
5, strong construction technology - mud pump mud mud filling bag filling to geotextile bag, make its consolidation type into the shape of the design requirements. Mud pump mud filling bag construction method is more complex, technical requirements and safety requirements is very high, meteorology, hydrology, geology, landform and so on the analysis of natural conditions; The requirements for engineering design, engineering node; Cloth, the sand quality selection, the Numbers and distribution of mud pump as a chain, which link the will directly affect the success or failure of the project.
6, underwater sand suction technology - mud pump suction sand cover suction, suction, suction etc, they all have in common need to ship with operation, can also can be directly to suction blow, but learned slurry concentration is not high, the impact of waves and tides is bigger also.
Mud pump common failures and troubleshooting methods
1, motor running but not turn slurry pump impeller, the reason may be that coupling or flat key damage, strong technical strength or impeller loss. Excluding method is to replace the coupling, reinstall the flat key or impeller strong technical strength.
Turn 2, mud pump, mud pond in motion, but not sucking mud mud pump. Reason may be that dredging tube road congestion, were covered with mud pump impeller sundry, damage of impeller, the impeller rotating in opposite directions, etc. Elimination method is through pipes, clear sundry, joint transform motor, ensure the normal operation.
3 mud pump, motor and abnormal sound, could be a slurry pump impeller jammed. To eliminate clutter.
4, small amount of mud pump out of the mud and may be a clutter of slurry pump impeller, or damage of impeller blade. Also have high lift, conveying distance too far. Or blocked at the pump cover the mouthpiece. Elimination method is clear sundry, change the impeller. Reduce the head, shorten the distance. Eliminate suction pump cover of sundry, ensure smooth tube.
5, mud pump vibration is too large, check whether the motor shaft and main shaft of mud pump is concentric, elimination method is correction concentricity, replace the spindle.
6, mud pump, pump casing wear serious, may be a flow blockage, the hard soil, replace or repair the mud pump pump shell. |
