Tai’an Ocean Pump Co., Ltd. pays more attention to the entire production process of the dredger pump. When matching the dredger pump impellers and dredger pump bearings , high torque dredger pump under different working conditions are designed to achieve continuous and stable transportation of long-distance delivery sand and mud with high concentration and large flow rate; the bolts are installed in strict accordance with the fixed torque to ensure uniform stress. In the process of continuous work, it is firmly assembled and not slipped off. In the process of supporting power, high cost-effective power equipment of international and domestic first-line brands are selected to ensure the maximum torque of the diesel engine or motor; the deep cooperation with auxiliary equipment manufacturers such as gear box factory, etc. Low rotation speed ratio gearbox suitable for sand dredger pump construction to ensure that the power and torque curves of the diesel engine and sand mining pump that are matched.
V. The Torque Design Application of Fredger Pump
One domestic customer from jiangxi province choose the 450GN-40 marine sand dredger pump for sand pumping in the offshore. our technical engineers conducted field surveys. Considering that the local sand is relatively loose, high concentration pumping sand, and the pipe plugging is extremely prone to occur. Therefore, when designing the project, match high torque diesel engine and gear box. 450GN-40 type marine sand dredger pump with flow capacity 3100m3/h, head 40m, rotation speed 550rpm, calculated shaft power 441.6kw, through the torque calculation can get the rated torque T=9550*441.6/550=7667.8N*m, engineers choose Jichai 12V190 type 1200 horsepower/1350rpm engine, and Hangzhou gear box 1260 type with reduction ratio 2:1, through the torque calculation T=9550*900/675=12733.3N*m, the bearing torque is far greater than the sand pump, in the actual pumping sand project, there was a high concentration situation. The amount of sand reached 1,000 cubic meters per hour, and the dredger pump torque was as high as 11,000 N*m. Since the diesel engine had a large torque margin, the dredger pump was very easy to run and the user was very satisfied.
