It is reported that the latest energy strategy development plan released by the Vietnamese government recently pointed out that by 2030, the total installed capacity of Vietnam’s electricity will reach 125-130 GW, which is double the current 54 GW.
According to Reuters, at present, Vietnam is one of the fastest-growing economies in Asia. The continuous economic growth has led to a surge in demand for electricity in Vietnam, and Vietnam’s power supply will be under pressure in the short term.
To alleviate the above situation, the Vietnamese government had to adjust its energy strategy development plan. According to the latest proposal, Vietnam has listed the oil and gas and renewable energy industries as a critical development direction, and proposed to increase the proportion of renewable energy to 15% -20% by 2030; by 2030, local refineries will at least meet the national requirements for refined petroleum products 70% of demand.
Among them, the bearing is an essential part of the equipment of the refinery. The inner and outer raceways of deep groove ball bearings are arc-shaped deep groove, and the channel radius is slightly larger than ball radius. It is mainly used to bear radial load and can also take the absolute axial load. When the radial clearance of the bearings is increased, it has the function of an angular contact ball bearing, can bear a large axial load, and is suitable for high-speed rotation. The bearing can still work typically when the housing hole and the shaft are relatively inclined 8 ′ ～ 16 ′, but it affects its service life. In the case of high speed and the thrust ball bearing is not suitable, this type of bearing can be used to bear pure axial load.
At the same time, the plan is clear, vigorously develop the construction of oil and gas infrastructure, encourage increased imports of liquefied natural gas; encourage local enterprises to seek foreign investment to accelerate the development and manufacture of new power plants, and accelerate the privatization process of state-owned power companies.
However, the Ministry of Industry and Trade of Vietnam said that domestic demand for electricity exceeded the speed of construction of new power plants, and the power market began to show a shortage of supply. It is estimated that by 2021, Vietnam’s power gap will reach 6.6 billion kilowatt-hours. In response, the Vietnamese government stated that it would make up for the expected shortfall in electricity by importing more coal and oil in the short term.
