Gearbox is widely used in motors, which is often used in wind turbine generator sets. It is an important mechanical component of the DC gearbox, whose main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it get the corresponding speed. Usually, the speed of the wind turbine is very low, far from the speed required by the generator for power generation. It must be achieved through the speed increase effect of the gearbox gear pair, so the gearbox is also called the speed increase box

China's super steel pipe for water delivery -- an important role of low-carbon drainage
The material of super water delivery steel pipe is about half of the traditional steel pipe. The connection adopts the flexible interface of self-aligning rubber ring, which is more convenient than the ductile iron pipe. It is safer and more economical than the prestressed concrete pressure pipe, and can be used to build a pipe network transportation system with a stronger water delivery capacity at a lower cost; China's steel pipe technology for water transmission has missed a step in the process of reform and opening up. It is relatively backward, but it has also accumulated leaping energy. China's super steel pipe for water transmission is already in action.

Architecture CAD Super Drawing King V4.1 Download
Under normal circumstances, the drawing of a building plan is quite complicated. A large number of wall lines need to be drawn in proportion, the positions of a large number of doors and windows need to be positioned in proportion, and the drawing of marking lines is trivial and troublesome. The super drawing king provides two tools to make this work easy and simple: after the double axis function inputs the size of the room, the software automatically generates the wall lines and corresponding labels of each room. The user only needs to trim these wall lines briefly, and the main part of the whole plan is completed. The marking function will mark the place where the door or window needs to be opened. Under the direction of the mark, the user can draw the door, window (all can be drawn in one stroke) and other objects, and the whole drawing is completed.

The hydraulic motor is an executive component of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Liquid is the medium to transfer force and motion. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical, port machinery, etc

The fixed casters have no rotating structure and cannot rotate. Usually, the two casters are used together. For example, the structure of the trolley is two fixed wheels at the front, and two universal wheels are near the pushing handrail at the back. Casters are made of various materials, such as cast iron wheels, nylon wheels, etc
