Leakless pumps have become the mainstream of today's petrochemical pumps

Associate Professor Luo Xianwu from the Institute of Fluid Machinery and Engineering at Tsinghua University said that the amount of pumps used is wide. In China, the power consumption of the pump system accounts for more than 20% of the total electricity consumption. The electricity consumption in the petroleum and chemical industries accounts for the entire country. 13.7% of social electricity consumption, a considerable proportion of which is used in pump systems. He pointed out that a considerable part of the current domestic petrochemical industry is lagging behind in process pump technology, and has lower operating efficiency and reliability. This not only wastes energy, but also results in equipment loss. Seriously causes the pump to have a short service life and endangers safe production.

According to Zhao Zhiming, vice chairman of the China Petroleum and Petrochemical Equipment Industry Association, toxic, hazardous, flammable, and explosive media are often transported during the production of petroleum and chemical products. Traditional mechanically sealed pumps are often difficult to completely eliminate running, running, and dripping. Leakage phenomenon not only causes economic loss, but also has great harm to the surrounding environmental protection and the health of employees. Statistics show that in the petrochemical industry over the past decades due to run, run, drip, leakage caused by safety and Environmental accidents account for nearly half of the total accidents.

According to reports, after many years of technical research, our country's scientific research personnel have developed their own non-leakage pump products. The non-leakage pump has been used in China Juhua 40,000 tons/year cyclohexane, Zhenhai refining 450,000 tons/year benzene Extraction, Shanghai Takahashi Dispersion BASF Corporation 200,000 tons/year SBR, Sichuan Lutianhua Tianhua BDO, Qilu Petrochemical Epichlorohydrin, Shanghai Secco Butadiene, Shanghai BASF Tetrahydrofuran, Jilin Petrochemical Methyl Isobutyl ketone projects and other projects provide technical support for the development of green chemicals and promote the sustainable development of the chemical industry.

However, the Industrial Pump Research Institute of Zhejiang University of Technology Industrial Engineering Yu Jiegang pointed out that the current overall level of pump technology in China is low, compared with foreign countries, 20 to 30 years behind, no leakage pumps, coal chemical industry diaphragm pumps and miscellaneous pumps and other sophisticated The technology of pump products is basically controlled by foreign monopoly. China's petrochemical pumps have a long way to go to surpass the world's advanced level.
