[The Stone of Haichuan and Other Mountains] The technical reform of the magnetic pump of the caustic soda plant is effective

Thread Content

Recently, news came from the chemical plant of Tianye Group Tianchen Chemical Co., Ltd. that the technical transformation project of replacing the fluoroplastic magnetic pump in the caustic soda plant of the plant has achieved remarkable results. The production process has achieved full sealing, no leakage, and no pollution.* * It reduces the accident rate, reduces the frequency of maintenance, and improves product production efficiency. Up to now, the caustic soda workshop of the plant has successfully replaced 9 centrifugal pumps with fluoroplastic magnetic pumps. 　　It is understood that during the production process of the caustic soda plant of Tianchen Chemical Plant, there are a large number of high-temperature liquid alkali of different concentrations. These liquid alkali are highly corrosive and can easily lead to leakage of the alkali pump seal, frequent maintenance, and pollution of the environment, causing certain difficulties in the maintenance and management of the equipment, and seriously affecting the production efficiency of solid alkali. To this end, the company decided to replace the ordinary mechanical seal centrifugal pump with a fluoroplastic magnetic pump that is compact, fully sealed, leak-free and reliable in operation. The fluoroplastic magnetic pump uses the basic principles of modern magnetism to achieve non-contact indirect transmission through permanent magnets. It does not require independent lubrication and cooling water. It has low power consumption and high efficiency. It has a certain safety protection effect on the motor and pump under overload conditions. Moreover, the fluoroplastic magnetic pump shaft has changed from a dynamic seal to a closed static seal, which completely solves the problem of mechanical seal leakage of the centrifugal pump, prevents the "escape and drip" phenomenon of alkali liquid, and eliminates potential safety hazards in production. 　　“Long-term operation results show that compared with traditional centrifugal pumps, this type of pump has more obvious advantages in operation, maintenance, safety and reliability. In the past, each alkali pump needed to be repaired at least 3 to 6 times a year. Since the self-fluorine plastic magnetic pump was replaced for more than a year, the equipment has been running smoothly and there has been no leakage problem. * * It reduces the frequency of inspections and maintenance and the downtime rate, saving at least more than 60,000 yuan in spare parts and labor maintenance costs a year. ”Su Dongfeng, deputy section chief of the alkali workshop of the plant, said.
