Due to its large dynamic performance, large operating radius, various performances of various parts and complexity, and the specialization of objects for obstacle rescue, heavy duty wreckers make it natural to consume large amounts of fuel. How to protect ro

The fuel cell provides full power quickly in less than a second and can withstand short-term overloads (a few seconds). Its features are ideal as a backup power supply or a safety-assured power supply. To achieve these dynamic characteristics, there must be an independent source of hydrogen on the

With the development of the wireless communication industry, the application fields of wireless transmission equipment are becoming wider and wider, but in some special fields, traditional wireless transmission equipment cannot meet its transmission requirements. In order to solve this situation,

Gear pump works: The concept of gear pump is very simple, that is, its most basic form is that the same size of two gears in a close-fitting rotation of the mutual engagement within the shell, the shell is similar to the internal "8" shape, two gears inside , The outer diameter of the ge

The status of technical patent applications can reflect the level of technology and innovation capability of a country or industry. Against the background of the impact of the global financial crisis, the number of patent applications for domestic sewing machinery continues to increase su

At present, research on gas dynamics and development of high-efficiency basic level, research and development of rotor dynamics and strength, development and optimization of thermal model, high-efficiency baffle heat exchanger in auxiliary machine system, new high-efficiency finned tube The desig

The ability of independent innovation is the core competitiveness of a country and the key to its survival and development. The laser cutting machine industry in China is still not strong enough, the added value of industry and labor productivity are still relatively low, the high l

High temperatures in summer can easily lead to a series of vehicle safety problems. A good habit of keeping a car in a safe place can avoid traffic accidents caused by motor vehicle component breakdowns and cause unnecessary personal and property damage. Here are a few summer car care precautions

In recent years, the concept of LED intelligent lighting has become more and more hot. In addition to controlling LEDs in terms of low power consumption, environmental protection, dimming and color matching, manufacturers continue to pay attention to another key wireless control of intelligent ligh

Since the mechanical emergency interrupt requires the actual overspeed test and is tested many times during the service of the turbine, the life of the unit is greatly reduced, and the test itself is dangerous. In addition to the actual overspeed test during the commissioning period or during the a

In the early days of reform and opening up, it was the rise of the free market economy. In the ancient town of Zhongshan, the lighting fixtures were like the fire of the stars. In the southern town of Liaoyuan, together with the holding of the Light Fair, the lighting capital was hammered! Formed a
