In daily life, many items experience rapid wear and tear due to improper use, incorrect operation, and other reasons, which significantly reduces their lifespan. In the process of providing services such as consultation, installation, and maintenance to various water pump users, Shanghai Kaitai Pump Industry has learned that many users are unable to use water pumps correctly, which leads to frequent malfunctions in these pumps. This shortens their service life and even affects the smooth operation of production and daily activities. Over the years, Shanghai Kaitai Pump Industry has continuously engaged in research and development, designing and manufacturing a wide range of pump types. Due to the different designs, structures, and working principles of these pumps, the methods for their maintenance also vary. Taking the G-type screw pump manufactured by Shanghai Kaitai Pump Industry as an example, several points that need attention during use are outlined here for users’ reference. First, before starting a G-type screw pump, it is necessary to determine the direction of rotation first; reverse rotation is not allowed. Although this pump can be reversed, it is advisable to operate it in the forward direction unless there are special circumstances, as this helps protect the motor and reduce wear and tear. Secondly, it is strictly prohibited to let the G-type screw pump run idle for extended periods without any fluid being pumped; otherwise, the stator will be damaged, which will prevent the pump from functioning properly. Third, pumps that have been newly installed or have been out of use for several days cannot be started immediately. Before starting, an appropriate amount of oil should be poured into the pump chamber, and then the pump should be turned a few times using pipe wrenches before it can be started. This helps to improve lubrication and reduce the impact of rust ； On the other hand, a manual trial run can check whether the pump has any inherent defects. Fourth, after transporting high-viscosity media or those containing particles or corrosive substances, it is necessary to rinse the pipeline twice with clean water or a solvent to prevent residue from remaining, which could cause blockages or corrosion of the pipe diameter and pose difficulties for future use. Fifthly, before using a G-type screw pump, lubricating oil should be regularly poured into the bearing housing. If leakage at the shaft end is detected, it should be addressed promptly or the oil seal replaced; this helps to ensure smooth operation of the pump and prevents the medium from leaking out. Sixth, when using it in winter, any accumulated liquid should be removed first, followed by thorough cleaning, to prevent the pump body from cracking due to low temperatures. Seventh, during the operation of a G-type screw pump, if abnormal noises, unusual movements, or poor flow are observed, the pump should be stopped immediately to investigate the cause; it can only be restarted after the fault has been resolved. The seven precautions to be followed by Shanghai Kaitai Pump Industry’s G-type screw pumps can also be used as a reference for other types of pumps in order to conduct inspections ； Alternatively, it is necessary to review the precautions outlined in the instructions for each type of pump and follow them strictly in order to ensure the sustained safety performance of the water pumps as well as a longer service life. This helps to extend the lifespan of the pumps, reduce related costs, and achieve durability and cost-effectiveness.
