According to reports, the 2N250 dynamometer was developed by the company in cooperation with Antai Power for two years. It has constant position, constant torque, constant speed and other characteristics. The net weight of the whole machine is 170 tons. The maximum test power is 55,000 kilowatts. The maximum speed is 150 rpm. The maximum absorption torque is 4500 kilograms. The speed measurement accuracy is plus or minus 0.1. The index/torque has a torque measurement accuracy of 0.3% FS and a torque control accuracy of plus or minus 0.5% FS. At the same time, in order to facilitate the centering connection with the diesel engine, the dynamometer can be three-dimensionally hydraulically adjusted, and the body can be moved 15 mm to the left and right.
At present, the company's full range of ship dynamometers are available in 1N125, 1N200, 1N250, 2N200, 2N250, 2N316, 2N350 and other models. It can test medium- and low-speed marine diesel engines with 210-980 mm bore.
Recently, respiratory diseases have been "stable" in the first place among the patients treated. Professor Tong Zhaohui, deputy director of the Institute of respiratory diseases, Beijing Chaoyang Hospital, said that winter and spring were the high incidence seasons of respiratory diseases such as acute upper respiratory tract infection, influenza and acute pneumonia. The high temperature provided many favorable conditions for many pathogens, and the breathing system was most susceptible to pathogens, so in warm winter, Respiratory infections will increase. In addition, the dry weather brought by warm winter also contributed to the fire.
"It's bad for human health if it doesn't snow." Mei Xue, deputy chief physician of the emergency department of Beijing Chaoyang Hospital, said that the air is dry, and people are prone to dry lips, bleeding nostrils and itchy throat.
Research shows that when the air humidity reaches 45% - 65%, it is conducive to the treatment and rehabilitation of lower respiratory tract diseases. When the air humidity is lower than 40%, the respiratory mucosa of nose and lung will be dehydrated and the elasticity will be reduced, making dust and bacteria easy to adhere to the mucosa, stimulating the throat, causing cough, pneumonia and asthma. Snow can purify the air and eliminate pollution. If it doesn't snow, it is easy to have multiple respiratory diseases such as asthma and pneumonia.
Experts suggest that when you go out in dry days, you must keep warm and pay attention to the temperature difference between indoor and outdoor. The indoor temperature should not be too high. The room temperature should be about 18 ℃ and the relative humidity should be controlled at 30% to 40%. For the elderly with respiratory diseases, it is best to wear masks when going out. In the weather with high air pollution index, outdoor activities should be reduced. It is recommended to breathe with your nose. Your nose can "humidify" the air, so as to purify the air and reduce the invasion of bacteria. Wash your hands more. When you go home from outside, you must wash your hands well with soap. In addition, we should also pay attention to drink more water, strengthen exercise, and ensure adequate sleep and nutrition
Experts suggest that in a dry environment, Aroma Diffuser can be used to alleviate air drying, moisturize the skin and solve the problem of drying
Huayang Power successfully developed marine high-power dynamometer
[China Ship Network (CnshipNet China)] It is reported that the 2N250 marine high-power dynamometer developed by Huayang Power Testing Equipment Co., Ltd. passed the acceptance test and was officially delivered to Jiangsu Antai Power Machinery Co., Ltd. The research and development results will break the monopoly of the ship dynamometer market by foreign companies, providing a greater choice for domestic customers. The acceptance results show that the performance indicators of the marine high-power dynamometer meet the design requirements, and can replace the imported dynamometer to perform various performance tests on the low-speed high-power diesel engine.
