On April 14, the “Guidance Opinion on Supporting Hainan's Comprehensive Deepening of Reform and Opening-up†issued by the State Council pointed out that scientifically and reasonably controlling the ownership of motor vehicles, accelerating the promotion of new energy vehicles and energy-saving and environmentally friendly vehicles, and gradually prohibiting the sale of fuel vehicles on Hainan Island. Although this guidance did not give a specific time plan for the ban on the sale of fuel vehicles on Hainan Island, at the “21st Century Maritime Silk Road Island Economy†sub-forum of the 2018 Annual Conference of the Boao Forum for Asia on April 9, Hainan Province Governor Shen Xiaoming once said that Hainan plans to use new energy vehicles on the island by 2030. At this point, Hainan became the first province in China to announce the ban on the sale of fuel vehicles. Bloomberg noted that the plan to ban the sale of fuel vehicles on Hainan Island is part of the Chinese government’s promotion of electric vehicles. In order to improve urban air quality and reduce dependence on imported oil, the Chinese government has implemented a new energy production quota system, hoping that sales of new energy vehicles will increase by a factor of seven, and considering bans on petrol vehicles. In 2009, China surpassed the United States as the world's largest automotive market, and in 2015 became the world's largest new energy vehicle market. Last year, the sales of electric vehicles in China accounted for about half of the world's electric vehicle sales. For Petrochemical Industry Chemical Pumps Petrochemical pumps refer to pumps used in petrochemical industry. Because almost all the transporting liquid is flammable, and most of the temperature and pressure conditions are harsh, higher or highest level pumps are required.

Requirements for petrochemical pumps in petrochemical plants
a. For petrochemical pumps that transport flammable, explosive, toxic or precious media, shaft seals must be reliable or non-leak pumps such as canned motor pumps, magnetic drive pumps, pneumatic diaphragm pumps, etc.
b. For petrochemical pumps that transport corrosive media, it is required to use corrosion-resistant materials for the flow parts.
c. For petrochemical pumps transporting solid particulate media, it is required that the flow-through parts be made of wear-resistant materials, and if necessary, the shaft seals should be washed with clean liquid.
Must meet site installation requirements
a. For petrochemical pumps installed in the presence of corrosive gases, measures to prevent atmospheric corrosion are required.
b. For petrochemical pumps installed at an outdoor ambient temperature below 20 ° C, it is required to consider the cold brittleness of the pump and use low temperature resistant materials.
c. For petrochemical pumps installed in explosion areas, explosion-proof motors shall be used according to the explosion area grade.
d. For factories that require major maintenance once a year, the continuous operating cycle of the pump should generally not be less than 8000h. In order to meet the requirements of a three-year overhaul, API 610 (10th edition) stipulates that the continuous operation cycle of pumps for the petroleum, petrochemical and natural gas industries is at least 3 years.
e. The design life of petrochemical pumps is generally at least 10 years. API 610 (10th edition) stipulates that the design life of centrifugal pumps for the petroleum, petrochemical and natural gas industries is at least 20 years.
f. The design, manufacture and inspection of petrochemical pumps shall comply with the relevant standards and specifications.
g. The pump factory should guarantee the performance of the pump within the range of the power supply voltage and frequency. China's power supply voltage and frequency change range is: voltage 380V ± 10%, 6000V ± 10%; frequency 50Hz ± 1Hz.
