The production and manufacturing of 24 centrifugal pump equipment for a foreign crude oil transportation project contracted by Panmao Technology has entered the sprint stage

On September 11, the manufacturing task of 24 main-line oil pumps (i.e.SZDP250-32centrifugal pumps) for a foreign crude oil transportation project contracted by Panmao Technology was nearing completion.This projecthas been scheduled since early January 2024 and lasted 8 months of production and manufacturing.20 of the products have completed assembly and water testing and have gradually entered the paint sealing stage.SZDP250-32The centrifugal pump is a new product independently developed by the company. The main line pump efficiency

reaches78%, exceeding the national standard by 4%. This product has the characteristics of long service life and high operational stability. It is used in oil pipelines with a total length of about 530 kilometers in extreme low temperature environments abroad.In the early stages of product design, the user expert group went to the company many times to organize technical discussions and put forward high requirements for the stability and safety of the product.公司技术团队围绕客户需求全新设计水利模型，针对串联工况下产品运行稳定性使用寿命、主线泵效率、极端低温环境运行以及实现远程控制与现场控制兼容等技术难点，公司技术团队多次进行技术评审

，制定了系列工作措施，有效解决了难、卡点，满足用户提出的各项技术要求。In addition, during the product design process, the company's technical personnelformulated plans based on mechanical calculation results to achieve axial force balance团队The user expert group has been stationed at the company to supervise manufacturing sincein June. They fully affirmed the seamless connection of various production processes at the company's production site for efficient operations and accurately realized the production efficiency of daily, weekly and monthly plans. They also gave unanimous praise to the heavy pump workers who are always fighting on the front line. Currently, the remaining four products are still being assembled in full swing. Heavy Pump employees will continue to work with full passion to contribute all their efforts to the accurate delivery of the company's key production orders.进行技术评审，制定了系列工作措施，有效解决了难、卡点，满足用户提出的各项技术要求。

此外，在产品设计过程中，公司技术人员根据力学计算结果制定方案实现变工况下的轴向力平衡，还结合实际工况制定机封备用方案，进一步保证了设备在用户现场运行的安全性和稳定性。

用户专家组自6月到公司驻厂监造，对公司生产现场高效作业各生产流程无缝衔接，精准实现日、周、月计划的生产效率给与充分肯定，为时刻奋战在一线的重泵职工给与了一致点赞。目前，剩余4台产品还在如火如荼装配中，重泵职工将就继续以饱满的工作激情，为公司重点生产订单的精准交付贡献出全部力量。
