Maoming Petrochemical: Innovation and transformation to improve the efficiency of pump operation

"Liu Gong, the circulating water pump J4221 / 22 of my chartered plane after your transformation is no longer due to drip problems, thank you very much." Gong Wenqiu, an outside operator of the high-pressure workshop of Maoming Petrochemical Chemical Division, performed charter flights every week at the scene. During routine maintenance, Liu Yu, who happened to meet the equipment inspector at the scene, couldn't help giving thumbs up.

In order to improve the class members to independently manage the on-site pumps, Maoming Petrochemical promotes that each class member is responsible for the daily maintenance of 1-2 sets of pumps. However, the circulating water pump J4221 / 22 mechanical seal of No. 1 high-pressure device often has the problem of circulating water leakage, which causes a low standard problem on the site.

Gong Wenqiu found the equipment engineer Liu Yu with the problem and sought a solution. Liu Yu's emergency team member was anxious and took the initiative to innovate. Through the dismantling research of the pump and reviewing the relevant information, it was found that the leakage problem was that the mechanical seal form of the pump was inappropriate. The original design of the machine seal is a Teflon plate, the moving ring is made of graphite, the material of the static ring is soft, and the static ring will be worn during the pump operation. Due to the tight force of the spring, there was no leakage during operation, but the worn parts after the start and stop caused the seal to fail due to the disappearance of the elastic force. The disassembly inspection found that the static ring was worn about 0.5mm. 磁力泵 转载发布;上海超乐主要生产 高温磁力泵 , 自吸式磁力泵 , 氟塑料磁力泵 , 塑料磁力泵 , 氟塑料自吸磁力泵 ; 不锈钢磁力泵 , 磁力旋涡泵 , 管道磁力泵 , 立式磁力泵 , 卧式磁力泵 , 衬氟磁力泵 等,咨询或订购 磁力泵 欢迎联系。 This article is published by Shanghai Chaole Magnetic Pump ; Shanghai Chaole mainly produces high temperature magnetic pumps , self-priming magnetic pumps , fluoroplastic magnetic pumps , plastic magnetic pumps , fluoroplastic self-priming magnetic pumps ; stainless steel magnetic pumps , magnetic vortex pumps , pipeline Magnetic pumps , vertical magnetic pumps , horizontal magnetic pumps , fluorine-lined magnetic pumps, etc. Please contact us for inquiries or order magnetic pumps .

If the material of the machine seal can be replaced and the strength of the machine seal can be strengthened, this problem should be solved. Liu Yu decided through various studies to transform the original PTFE static ring into silicon carbide, and the material of the mechanical seal was enhanced. At the same time, he creatively proposed to design a machine seal washing line to regularly clean up the impurities attached to the machine seal to avoid damage to the machine seal.

In the recent overhaul, Liu Yu implemented the transformation plan. After the transformation, the mechanical seal of the pump is used normally, which eliminates the problem of dripping, prolongs the life of the pump, greatly facilitates the daily maintenance of employees, and is praised by employees.
