Last month, the coil in the ultra-low temperature liquefied natural gas (LNG) pump used by a customer was aged and damaged after long-term use, causing the customer's equipment to stop. The customer's production is very busy and the product value is very high; a day of downtime would cost hundreds of yuan in losses. The customer consulted several motor manufacturing and repair companies, none of which were confident to repair it. Later the customer contacted us. With the customer's cooperation, we used our special materials and processes to successfully repair the coil in the shortest time. At present, the customer's equipment is in good condition.
