Cutter Suction Sand Dredger

Applications of theCutter Suction Sand Dredger
The Yongsheng Shipyard cutter suction sand dredger is designed for sand borrowing in sandy waters and river channels. It can also be used for river channel rectifying. It has many advantages such as reliable performance, easy maintenance, long service life, low operating cost and a large working load of 500-2000 cubic meters moved per hour. After careful selection and separation, the cutter suction sand dredger will discharge pure sand which is optimum for construction cement production.

Details

Cooling Water Filtration System

Cooling Water Filtration System
The cooling water filtration system can operate automatically and clean periodically, ensuring that the water pipes are clean and unobstructed.

PLC Control System

PLC Control System
The PLC control system from SIEMENS has high reliability, strong anti-interference ability, and good applicability with comprehensive accessories. Its 12v PC switch panel can provide reliable security protection.

Hydraulic Oil Filter

Hydraulic Oil Filter
The hydraulic system is equipped with a large size of specially manufactured hydraulic oil tank. The filter consists of housing and a filter element with countless tiny holes to filter the contaminants in hydraulic oil.
Hence, we specially designed a filter component for hydraulic oil filtration but it needs to be cleaned periodically, ensuring the cleanness of hydraulic oil. The hydraulic oil filter is usually equipped with a coarse filter and a fine filter.

Voltage Stabilizing System

Voltage Stabilizing System
The automatic voltage stabilizing system in generator can output stable voltage when dredger is operating. When rotational speed of the main engine is changed, it can automatically adjust its field rheostat, so as to stabilize the output voltage and ensure the normal operation of dredger power system.
It is necessary equipment for dredgers with high reliability and durability.

Engine System
Yong Sheng offers different brands of engines, like Weichai, Yuchai, Cummins, MWM, etc. Since engine is the most important component of dredger, Yong Sheng will choose the most reasonable engine on your request.

All of our dredging equipment is made using steel plate, and we can design each cutter suction sand dredger according to customer requirements.

Maintenance tips
1. While starting the cutter suction sand dredger, start the single cylinder engine first and then start the multi-cylinder engine. After that, slowly put down the spout and stop when the diesel engine can't bear. Then control the spout according to the concentration of the sand discharging port.
2. If the displacement of the sand is very small, the spout may be blocked by stone. Put up the spout to a height of 50cm and slow down the accelerator, then increase the accelerator and put down the faucet. If this kind of situation happens again, you should change the operating location.
3. The longer the sand suction distance, the smaller the sand concentration. The concentration is about 50% when the distance is 30m.
4. If the water can't be drawn out, you should check the sand suction pump to see if there is any steam leakage. If the draft of the pump is shallow, you need to increase the sandbag.
5. When the diesel engine is struggling, you need to check the triangular belt and the sand suction concentration.
