Not long ago, a certain power engineering company reported that the Huiyi Power 4000kVA/800kV series resonant device they purchased had a slight oil leakage at the bottom of the reactor during use, which affected the normal operation of the equipment. After receiving the feedback, the after-sales team of Huiyi Power responded immediately and strictly followed the company's after-sales process. They quickly dispatched professional after-sales engineers with special maintenance tools to the site to troubleshoot the fault. The entire process was highly coordinated, minimizing the loss of the customer's construction period as much as possible, and demonstrating their commitment to after-sales service through their actions.
After the after-sales engineer arrived at the site, he did not simply conduct random repairs. Instead, based on his many years of experience in inspecting series resonant equipment, he conducted a comprehensive and meticulous inspection of the reactor and systematically identified the causes of oil leakage one by one. Through professional testing, it was ultimately determined that the slight oil leakage at the bottom of the reactor was not a quality issue of the equipment, but rather an operational error by the customer's operators during installation and commissioning, which led to the loosening of the fixing screws at the bottom of the reactor, thereby causing the slight oil leakage. This situation is highly consistent with the common maintenance procedures for reactor oil leakage, where loose fasteners cause leakage, and it is a routine problem that can be quickly resolved.
After identifying the cause, the after-sales engineer immediately formulated a targeted handling plan. In accordance with the maintenance process standards for reactors, he conducted a comprehensive inspection of all screws at the bottom of the reactor and systematically checked for any loosening. For the loosened screws, he used professional tools to precisely tighten them and made minor adjustments. He adjusted the tightness of each screw in a cross-diagonal manner repeatedly to ensure that each screw was evenly stressed and to avoid any further loosening or oil leakage problems due to uneven stress. After the handling was completed, the after-sales engineer also conducted a sealing test on the reactor to confirm that there was no oil leakage. The equipment's operating parameters returned to normal, and the customer's troubles were completely resolved.
During the maintenance process, the after-sales engineers also patiently explained to the customer's operators the correct operation procedures and daily maintenance points of the 4000kVA/800kV series resonant device. They particularly emphasized the precautions for tightening the screws at the bottom of the reactor, reminding the operators to regularly check the tightening status of the screws during subsequent use to avoid equipment failures caused by operational errors. At the same time, they answered various equipment usage questions raised by the customers on-site and provided professional technical guidance, enabling the customers not only to solve the current problems but also to master the skills for daily maintenance of the equipment.
