The gearbox of a wind turbine is one of the key components in wind power generation equipment, used to transfer the kinetic energy of the rotating wind turbine to the generator, thereby generating electrical energy. It is usually composed of multiple gears, which increase the speed of the wind turbine through precise transmission ratios and convert it into a speed suitable for the operation of the generator. Usually, the speed of the wind turbine is very low and far from the required speed for the generator to generate electricity. It must be achieved through the speed increasing effect of the gearbox gear pair, so the gearbox is also called a speed increasing gearbox.
Our company supplies spare parts for wind turbine gearboxes: gears, etc.

Infrared optical lenses are specialized optical lenses designed specifically for receiving, focusing, and processing infrared wavelengths (typically referring to electromagnetic waves with wavelengths ranging from 0.76 1/m m to 1000 m). They differ fundamentally from the visible light lenses we are familiar with (such as camera and mobile phone lenses) in terms of design, materials, and working principles. Their core task is to efficiently transmit infrared radiation and form high-quality images.
In simple terms, it is an "eye" that enables "infrared cameras" to discern the temperature and outline of objects.

Definition:
5N polycrystalline Germanium Ingot refers to a high-purity polycrystalline germanium material with a purity of 99.999% (five nines), which is often refined through the Zone Refining method. It is used in the manufacturing of infrared optical components, semiconductor materials, optoelectronic devices and other high-end fields, and is the basic raw material for manufacturing high-quality optoelectronic products.
Production process:
The 5N Zone melting germanium ingot is a high-purity germanium metal material obtained through the Zone Refining method, with a purity of over 99.999% (5N), and some products can even reach 6N-8N (99.9999%-99.999999%). The zone melting method utilizes local heating to make germanium material solidify directionally in the molten zone. Through multiple purifications, impurities are concentrated at the end of the ingot and removed, ultimately obtaining high-purity polycrystalline germanium ingots.
The production process adopts segmented variable-speed zone melting technology, combined with the switching between high-purity nitrogen and nitrogen mixed gas, to achieve deep purification. Meanwhile, through graphite boat coating treatment and specific equipment design, the silicon content is controlled below 1ppb (parts per billion) to ensure the surface quality of the material.

The Axial turbine is for low head power plants. Water flows axially into and out of the turbine. Axial flow turbines fall into two categories, fixed blade runner and variable pitch runner, also known as a Kaplan turbine.

Fixed blade turbines are very well suited to low head power plants with limited variation in head and load.
Its main advantage is its simple design. When operated at fixed speed, maximum efficiency is achieved at the design head and water flow.

Kaplan turbines are used for medium to large power stations where there are large variations in the head, water flow and load.

Its main advantage is its ability to adapt to variable conditions with a high efficiency. The variable pitch runner is mechanically more complex than a fixed pitch runner. Axial flow turbines can be supplied for a head of 2m to 70 m. The runner diameter is available from 0.6 m to 5 m. Power capacity is from 55 kW to 50 MW.

Pelton turbine

The runner has bucket shaped blades on the periphery. The jet of water is tangential to the runner.
The characteristics are, high head applications, a simple design, few problems with cavitation, highly cost effective.
Pelton turbines can be supplied for a head of 100m to 500 m. The runner diameter is available from 0.55 m to 1.5 m. Power capacity is from 200 kW to 10 MW.

Inclined jet turbine:
The water flows into and out of the runner at an angle to the main shaft.
The characteristics are high efficiency over a wide range of water flow, more flexible installation options, somewhat more complex than a Pelton turbine.

Inclined jet turbines can be supplied for a head of 60m to 300 m. The runner diameter is available from 0.32 m to 0.8 m. Power capacity is from 55 kW to 6.3 MW.

In a Francis turbine, the water flows radially into the turbine and axially out of the runner. The Francis turbine, invented by an American engineer in 1849, is the most widely deployed modern turbine. The main characteristics of the Francis turbine are - a wide range of water head, simple and reliable structure, and high efficiency.


A Francis Turbine can be supplied for a head of 15 m to 250 m. The runner diameter is available from 0.4 m to 4.5 m. Power capacity is from 75 kW to 50 MW.
