Cutter suction dredger should not blindly follow the trend, it is also called suction sand pumping vessel, divided into the cutter suction dredger, jet suction dredger, drilling pump dredger, it is the use of sand suction pump suction to underwater sludge and sand suction through the sand discharge pipe to the specified location, it is pumping sand the way of working. As the demand for artificial sand increases, resulting in demand growth and pumping sand, sand pumping by the public familiar with the future development, sand pumping was great. Now pumping sand manufacturers is also more and more, blindly follow the trend is not terrible, to choose their own dredging vessels, in order to bring benefits, the lead you to understand some of the common mistakes:
1. imported parts, some users feel that imported something is good, that can withstand the wear parts in use, the parts in the domestic developed countries in Europe do not have imagined so good, especially the parts sometimes temper, easy to cause the accident, and is based on various types of domestic production, price reasonable, more suitable for cutter suction dredger.
2. remove the engine thermostat, some users believe that the engine temperature is high because of the thermostat's sake, in fact, is wrong, the cooling liquid can only proceed big circulation, can adjust the cooling intensity, it is difficult to ensure the engine working at a suitable temperature, but will make the engine often in low temperature, causing the engine power down, wear faster, increased fuel consumption.
3. lubricating oil, due to different types of cutter suction dredger, lubricating oil is not the same, according to the displacement and compression ratio of performance level selection, and then according to the load, temperature and viscosity level selection, do not blindly follow the trend, to choose suitable for lubricating oil of cutter suction sand pumping their use from the following aspects.
