Once the products manufactured by a company are sold, if after-sales service is inadequate, many of the users’ rights and interests may not be properly protected, leaving them with concerns. Therefore, users may feel uneasy while using the product, which in turn leads to doubts about it. Actually, this is all normal. Since its establishment, Shanghai Hongdong Pump Industry has taken this phenomenon fully into account, making every effort to address issues before they arise, and has received high praise from a large number of users. “Majestic as I am, with the sunrise in the east, I move forward on my journey, striving onward. ”This is not just a slogan of Shanghai Hongdong Pump Industry; it is also the approach and goal that guide the company’s pursuit of sustainable growth. Shanghai Hongdong Pump Industry uses this motto to inspire the passion and determination of its employees; by focusing on achieving high product quality, it also pays attention to improving the level of after-sales service, which has earned it a great reputation throughout the national pump industry. Judging from the comprehensive solutions it provides for after-sales issues with LQRY high-temperature oil pumps, Shanghai Hongdong Pump Industry truly lives up to its reputation in terms of service. The company consolidated the issues reported by users along with those that may arise during the operation of water pumps, identifying eight types of faults. It analyzed the causes of each fault and developed solutions for addressing them, providing users with thorough guidelines for performing maintenance and fixing problems on their own. This approach helps to save users time spent on repairs and **improves work efficiency. For example, the fault in which the LQRY high-temperature oil pump fails to draw liquid was attributed to eight possible causes: no liquid being filled in the pump, blockages in the suction pipe, discharge pipe, or the pump’s flow channels, residual gas in the suction pipe or inside the pump, the suction height exceeding the allowable limit, the discharge pipe being too narrow, excessive losses in the pipes, using a head higher than the designed value, transporting hot and volatile fluids, and the wrong direction of rotation. Eight solutions were proposed corresponding to the eight causes: refilling the pump, removing debris, inspecting the suction pipeline and venting gases, reinstalling the pump at the allowable suction height, replacing with a suitable discharge pipeline, selecting a different pump, reducing the suction lift or installing it in reverse flow, and correcting the rotation direction. At the same time, the LQRY high-temperature oil pump may also suffer from seven types of faults: insufficient flow rate of the heat transfer oil pump, insufficient head pressure of the heat transfer oil pump, severe vibration of the heat transfer oil pump, overheating of the bearings in the heat transfer oil pump, severe leakage in the mechanical seal of the heat transfer oil pump, severe leakage in the packing seal, and overheating of the motor used in the heat transfer oil pump. For each of these faults, there are scientific and reasonable underlying causes as well as solutions. These specific methods adopted by Shanghai Hongdong Pump Industry not only improve the efficiency of users’ work but also provide references for the development of China’s pump industry. Shanghai Hongdong Pump Industry has always placed great emphasis on after-sales service, continuously improving the standard of its services to genuinely address the concerns of its customers, and for this reason it has received high praise from a large number of users.
