On October 1, 2014, most of the petrol stations in Sinopec Hangzhou began to sell the national standard gasoline and the national standard diesel. According to the plan, on November 1st, all gas stations in Hangzhou-Jiaxing-Huzhou area will supply the national standard gasoline and the national standard diesel fuel supply; on January 1, 2015, all the gas stations in Zhejiang province will realize the supply of national standard diesel fuel for vehicles; 2016 On January 1st of the year, all the gas stations in the province realized the supply of the national five standard gasoline and the national five vehicle diesel. After the upgrade, Hangzhou will become the third provincial capital city after the use of the country's five standard gasoline after Nanjing and Guangzhou. Zhejiang will also become the province of the country to use the country's five standard gasoline earlier.
It is understood that at present, Zhejiang Province's motor gasoline is the national standard and the vehicle diesel is the national standard. After the upgrade, the limit value of sulfur content of gasoline for vehicles in Zhejiang will be reduced from 50ppm in Guosi to 10ppm and reduced by 80%. The diesel quality upgrade will go from the national three to the national four, going straight to the country five, the sulfur content limit will be reduced from 350ppm in the country three to 50ppm in the country four, and then to 10ppm in the country five, a 97% reduction.
Diesel has been upgraded to the main channel for the production and supply of refined oil products in Zhejiang. Sinopec Zhenhai Refining & Chemical and Zhejiang Petroleum have been committed to the improvement of oil quality. Based on the common purpose of serving the localities and creating a clear blue sky and blue sky, the company has organized and implemented the country in advance. The standard vehicle diesel and the national five standard gasoline were upgraded, and as early as the beginning of 2014, they began to actively prepare for the early stage and plan to replace them as early as possible.
In order to cope with the upgrade of the oil quality, Zhejiang Petroleum also revised the grades of the national five-vehicle gasoline, and the 90th, 93rd and 97th were adjusted to 89th, 92nd and 95th respectively. The National Standard No. 92 gasoline is suitable for vehicles that originally used No. 93 gasoline; the No. 95 gasoline is suitable for vehicles that originally used No. 97 gasoline; and the national four-vehicle diesel is upgraded and the label is unchanged. During the replacement period, the national standard gasoline and the national standard gasoline, as well as the national standard diesel and the national standard diesel, can be mixed and filled.
According to reports, the oil quality of Sinopec gas station after listing is in line with the requirements of the new standard. The LED or banner inside the station will announce that “the gasoline of this station has been upgraded to the national five standard, and the diesel has been upgraded to the national four vehicle standard”. At the same time, the invoices and IC card tickets marked with the national five gasoline or the national four vehicles are issued to ensure that the gasoline and diesel products sold are consistent with the announcement and relevant documents.

Sealed Nylon Cage Bearing

Sealed Nylon Cage Bearing is one type of Deep Groove Ball Bearing with unique nylon cage. It is often used in the mine. has better anti-stuck performance and wider range of temperature than iron cage. In the underground its anti-static performance is also better. It is best cost-effective bearing for idler roller.

The selection of sealed nylon cage is crucial to KA bearing with one or double seals, while the material of nylon cage must be pure and has enough toughness and strength, because the cage will get very soft if it is made of bad material or mixed material, thus to make no anti-stuck performance within the bearing. To get safety certificate for coal mining products must use nylon cage bearing.
