With the state's policy support for solar power generation, whether it is photovoltaic power generation or solar thermal power generation, it has focused on people's attention. However, the cost of photovoltaic power generation remains high, and how to locate the on-grid tariff is still unknown. Academician Huang Qili said on the same day (8th) that as the price of solar energy decreases year by year and the price of thermal power rises steadily, the price will no longer be a bottleneck restricting solar power generation in a short period of time.
Huang Qili: "Photovoltaic electricity prices have dropped by about 6-8% every year in recent years, and the rate of conventional electricity prices and coal-fired power increases by 6%. The convergence of these two curves is in 2015 and 2016. It is expected that by 2020 Power generation and conventional electricity prices are balanced. That is to say, the difficulty of high cost in the initial stage of development can be solved within 5-10 years."
Zhao Zhongxian, an academician of the Chinese Academy of Sciences, said that the main source of renewable energy in China and the United States is hydropower. Both countries are committed to increasing the share of other renewable energy resources.
Zhao Zhongxian: "From now to 2020, wind energy, solar photovoltaic, solar thermal, traditional geothermal energy, and some biomass power generation will gradually expand in size and prepare for accelerated application."
Experts believe that in the next decade, China and the United States will become the world's two largest renewable energy application markets, and the two countries need to jointly address the challenges of large-scale application of renewable energy.
Zhao Zhongxian: "The effective combination of China and the United States' capabilities and experience will also make these technologies easier to promote on a global scale, enabling renewable energy resources to be effectively utilized in more countries."
Common types and uses of pliers
Pliers have many functions and are used in many industries. The pliers used in different industries are also different. Generally, the more commonly used pliers are:
1. Wire stripper
Wire strippers are commonly used tools for internal electricians, motor repairs, and instrumentation electricians. They are composed of knife edges, crimping ports and clamp handles. They are mainly used for stripping plastic and rubber insulated wires and cable core wires.
2. Wire cutters
Also called a vise, it is a kind of clamp and cutting tool. It is composed of jaws, tooth edges, knife edges, guillotines and pliers handles. It is mostly used to pick up nails or break nails and iron wires.
3. Nozzle pliers
It can be divided into electrical and electronic categories. It is mainly used for cutting injection molding machine products, plastic products, and injection nozzles. It is also suitable for cutting metal products and electronic component pins.
4. Needle-nose pliers
Also known as trimmers, pointed pliers, and pointed pliers. They are composed of pointed tips, knife edges and pliers handles. They are generally made of 45# steel. They are used to cut single and multi-strand wires with thinner diameters and to give orders. Stranded wire joint bending, stripping of plastic insulation layer, etc., can be operated in a relatively small working space.
5. Curved nose pliers
Also called elbow pliers, its function is similar to that of needle-nose pliers without cutting edge, and it is suitable for use in narrow or recessed working spaces.
6. Flat nose pliers
It is a commonly used tool for assembly of metal parts and telecommunications engineering. It is generally used to bend metal sheets and metal filaments to make them into the required shape. In repair work, they are used to install and pull out pins, springs, etc.
7. Diagonal pliers
Mainly used to cut metal wires, flat-nose diagonal pliers are suitable for use in recessed working spaces.
8. Top cutting pliers
End-cutting pliers are similar to diagonal pliers. They are mainly used for cutting steel wires with the cutting edge at the top.
9. Water Pump pliers
The function is similar to a pipe wrench, but it is lighter, smaller and easier to use than a pipe wrench. However, the clamping force is not as good as a pipe wrench. Generally, it is only suitable for household non-professional emergency or simple installation of water pipes.
10. Slip joint pliers
The shape resembles a carp. The opening width of the jaws has two adjustment positions, which can be enlarged or reduced. It is mainly used to clamp round parts. It can also replace small nuts and small bolts with a wrench. It is often used in the auto repair industry.
11. Circlip pliers
Commonly known as circlip pliers, it is a special tool used to install inner and outer circlips, and can also be used to remove circlips. .
12. Vigorous pliers
It is mainly used for clamping parts for riveting, welding, grinding, etc. It can also be used as a wrench. Its characteristic is that the jaws can be locked and generate a large clamping force to prevent the clamped parts from loosening.
