According to the CSSC Group, China Shipbuilding Electronics Haiying Company has successfully developed the HY1300 self-contained tide gauge for two years, reaching the international level of similar products and achieving mass sales. The HY1300 self-contained tide gauge is a pressure type tide g
For some power plants with lower stability margins, any failures that occur may cause some or all of the generators in the plant to lose synchronization. For a given fault, the longest fault duration that guarantees that the system will not lose synchronization is called the critical cut-off time
If the car is driven more, the tires will wear out. This does not mean that we have problems with driving, but it is inevitable that normal driving will happen. However, tire failure is very dangerous. It may make your car out of control. It may also throw you in a ghost place that is not in front
On September 8, 2015, the acceptance meeting for the National Twelfth Five-Year Plan for Science and Technology Support Program was held in Weichai . At the meeting, an expert group led by Cao Xuejun, deputy director of the Advanced Manufacturing and Automation Division of the Ministry of Sc
At the Frankfurt Motor Show, which opened recently, Ding Lei, co-founder of the new music car, made a public appearance. This is the first show of Ding Lei's return to the automotive industry in important public occasions. Previously, there have been multiple versions of Ding Lei’s retu
Visible from Equation 1), the adjustment coefficient! Indicates the relative change in generator voltage when the reactive current increases from zero to the rated value. The smaller the adjustment coefficient, the smaller the generator voltage change when the reactive current changes. So, the ad
For the production of silicon steel sheets (矽钢片), in the past, general molds were used on ordinary punching machines; as the demand for silicon steel sheets became larger and higher, the precision was higher and higher, and the traditional production methods could not meet the req
Juices are juice products made from fresh or frozen fruits as raw materials by physical methods such as pressing, centrifugation, extraction, etc., and generally refer to pure juice or 100% juice. In the production process of fruits and vegetables, in order to ensure its yield and quality
Recently, Shougang Tonghua Iron and Steel Group Co., Ltd. successfully produced a bar code of GCr15, with specifications of 25, 28, 32 and 35 high carbon chromium bearing steels with a total capacity of more than 200 tons. The technical specifications are in full compliance with GB/T18254- 2002 nati
The necessity of tire pressure monitoring system! The main reason for a car puncture is that there is no real-time monitoring of the tire pressure, and the tire pressure of the car will decrease with use, until the puncture is difficult for the user to perceive the tire pressure. Tire Pressure Mo
The sway of the generator (<5-0 curve is one of the important basis for analyzing the transient stability of the power system and the time to cut the fault limit. The essence of the rocking curve is to solve the rotor motion equation of the generator, and improve the Euler The method is a roto
In Shunchang, there is a private high-tech instrument company with more than 400 national patents associated with the Shenzhou spacecraft and the Lunar Exploration Project. It not only promotes local employment, but also contributes to the “Made in China 2025â€. Please see â€
