On February 22, Dongming Petrochemical Wanhai Chlor-alkali Group successfully launched a phase dechlorination system vacuum pump, marking a successful completion of the localization of the vacuum pump rotor. Up to now, the pump has run well and the indicators have been normal. The total cost of the pump has been saved by more than 130,000 yuan, and the smooth operation of the equipment has been ensured.
On December 15 last year, the electrolytic dewatering system used in Japan imported a liquid-ring vacuum pump rotor, and Dongming Petrochemical Wanhai chlor-alkali group contacted Dongming and Heze. Many maintenance departments and several domestic titanium pump manufacturers all told that they could not be repaired. , Through the purchase center of the marketing center to contact the Japanese original manufacturer's original rotor quotation to 156,000 yuan, and the supply period of at least five months, in order to save costs, while ensuring that the rotor timely recovery and standby, Dongming Petrochemical Wanhai chlor-alkali group after full Discussion, decided to carry out the domestic transformation of the rotor. Through comparison and understanding, Suzhou Longfeng Titanium Nickel Equipment Co., Ltd., which is well-known in China, has been selected for transformation. In order to ensure a successful transformation, Suzhou Longfeng has arranged experience and theoretically rich engineering and technical personnel to conduct in-depth surveying. Dongming Petrochemical Wanhai chlor-alkali group equipment and maintenance workshops and company leaders have gone all out to actively assist with the transformation. After a full two months of repeated surveying, processing, and testing, the installation was finally completed on February 22nd.
