“…Consequently, maintaining the proper seal water pressure at the shaft is imperative for the uninterrupted and regular operation of the mud pump. Deviations in sealing conditions can result in slurry leakage around the pump, leading to issues such as corrosion and premature bearing failure [7]. Therefore, the seal water pressure must be higher than the pressure on the shaft side to ensure sufficient flow to flush sediment to a safe area [8,9].…”

The mud pump water sealing system (MPWSS) is important in the efficient operation and prolonged service life of the cutter suction dredger’s (CSD) mud pump. Considering that the underwater pump operates underwater and the shaft seal water pressure sensor is prone to failure, a hybrid deep learning model MCNN transformer is proposed to predict the underwater pump shaft seal water pressure in the event of sensor failure. This paper uses big data from the dredging project to deeply excavate the relationship between the shaft end sealing water pressure and other construction data by combining experience and artificial intelligence, and then uses multi-scale convolutional neural network (MCNN) to reconstruct the data, highlighting the time series characteristics of the multi-scale data were then input into the transformer model for prediction, and compared with a single MCNN, transformer model and four other neural networks. Finally, the cutter suction dredger “Hua An Long” was selected as an application research case; experimental comparisons were conducted on seven different models to verify the accuracy and applicability of the MCNN-transformer model.

The rotating face mechanical seal principle is adaptable to serve a tremendous number of sealing needs standard mechanical seals can suit most requirements-including temperatures and shaft speeds through the choice of secondary seal and the combination of seal and seal face materials which are offered. Seals can be ordered in balanced configurations to seal pressures or used in a multiple for extremely high pressures or especially severe fluid services. Special mechanical seals can be furnished to meet the most demanding of industrial applications considering pressure, temperature, speed or fluid.

“…(Haimann et al, 2014) presented an integrated suspended sediment monitoring strategy and proved that the suspended sediment transport's temporal variability can be determined more precisely compared with other available methods. (Ridgway et al, 2009) studied the seal wear characteristics of slurry pump gland and reported that the particle properties like relative hardness, fracture toughness and size of the shaft sleeve get affected by the particle inorganic chemistry. (Khazam and Kresta, 2009) used three impellers of two diameters and compared the full baffle configuration with two partial height baffle arrangements and found that the performance of surface baffles is superior to full or half baffled configurations.…”

The erosion of the blades of hydraulic pumps and turbines, caused due to the water that has enormous suspended particles and erosive agents, is a severe global challenge among scientists and engineers. In the present work, an attempt has been made to compute the extent of erosion caused by water when it passes through devices like hydraulic machines, centrifugal pumps and turbines. Experimental and computational techniques using pitched turbine blades with 45o with the horizontal plane under down pumping condition is employed for investigation of the suspension phenomena for calculating erosion wear by sand suspended in water in river, canal on turbine, pump blades. An experimental set up, named as Accelerated Erosion Test Rig (AETR), is developed through dimensional analysis. For experimental analysis, the sand particle size and propeller dimensions were varied while running the propeller at different speeds. Experimental results revealed that the propeller speed must be maintained at an optimum value, preferably lower speeds, to ensure maximum lifting of impurities and sand particles from the base of the cylinder.
