"If the follow-up policies of the State's "Energy Conservation and New Energy Vehicle Subsidy Policy" can be launched as soon as possible, our hybrid and pure electric passenger vehicles will maintain rapid growth." According to the State Council's "Opinions on Accelerating the Development of Energy-saving and Environmental Protection Industries" (hereinafter referred to as " "Opinions"") specifically proposed to speed up new energy vehicle technology research and demonstration and promotion. The relevant person in charge of the Yutong Bus R & D Department told reporters yesterday that if this is good, the prospects for new energy buses will be even brighter.
The "Opinions" require that the implementation of energy-saving and new energy automotive technology innovation projects be accelerated, and the innovation of power battery technology should be vigorously strengthened, with emphasis on solving the problems of safety, reliability, and lightness of the power battery system; accelerating the improvement of supporting industries and charging facilities, and promoting and demonstrating pure electric power. Automobiles and plug-in hybrid vehicles, aerodynamic vehicles, etc. The "Opinions" also give a series of support policies that favor the development of new energy vehicles.
It is worth noting that the "opinions" also pointed out that Beijing, Shanghai, Guangzhou and other cities have expanded the scope of demonstration and promotion of new energy vehicles in the public service sector, and the proportion of newly added or updated new energy vehicles in buses has reached more than 60%; Purchase pilot subsidies for new energy vehicles and new energy taxis and logistics vehicles. “This requirement is expected to release the replacement demand of Beishangguang and other large cities in advance, which is good news for new energy bus companies.†Ankai, deputy general manager of Ankai Bus, told reporters.
According to Wang Xianfeng, the current market share of new energy buses is less than one-third in large cities such as Beishangguang. "We have already begun to enter markets such as Guangzhou and Beijing. Especially in Guangzhou, one of every three new energy buses is Ankai."
According to relevant sources in the Yutong Bus R&D Department, the company is currently increasing its product R&D and production capacity. By the end of the year, the company's production capacity will reach 20,000 units.
Zhang Yong, deputy general manager of Chery, suggested that all localities should break the regional restrictions in the development of new energy buses and select the appropriate models to allow them to have full access to development opportunities.
Excavator Cylinder Piston Seals
Precautions for the installation of hydraulic cylinder piston seals in excavators
1. The sealing of the oil cylinder piston should use products of reliable quality to ensure good sealing performance.
2.Before installing the oil cylinder piston seal, the seal and sealing groove should be cleaned to ensure that the sealing surface is free of impurities.
3. When installing the seal, the correct installation sequence and direction should be carried out according to the drawing requirements to ensure the correct installation of the seal.
4.When installing the seal, special tools should be used to avoid using sharp tools and hard objects to damage the seal.
5. When installing the seal, attention should be paid to whether the seal groove is damaged or worn. If so, it should be replaced or repaired in a timely manner.
6. When installing the seal, an appropriate amount of lubricating oil should be applied to avoid friction damage to the seal during installation.
7.When installing the seal, it should be ensured that the compression of the sealing ring meets the requirements to avoid excessive or insufficient compression leading to seal failure.
8.After installing the seal, a sealing test should be conducted to ensure that the sealing performance meets the requirements.
