Refrigerant For Inverter Controller
High temperature is easy to cause circuit safety problems, and the instrument in the circuit is no exception. In summer, as far as the frequency converter is concerned, which is indispensable for equipment control and speed regulation, the hot weather is the heat and hard injury of the frequency converter. A large number of studies and practices have shown that the failure rate of the converter will increase with the increase of temperature, the service life will decrease with the increase of temperature, and the service life of the converter will be halved with the increase of ambient temperature by 10 degrees. For this reason, high temperature is coming, how we use fluoride solution to effectively cool down? Please contact us by email.

The lawyers Huang Peiping, Han Shichun, and Ye Mingxin of the Beijing Yilian Labor Law Aid and Research Center wrote to the Ministry of Land and Resources on February 25 to disclose the detailed results of groundwater quality monitoring in 200 cities nationwide. Huang Leping said that the contents released by the Ministry of Land and Resources at present only provide a summary of the monitoring results, and neither the specific monitoring results nor the names of these cities have been announced. Recently, the issue of water pollution has attracted more attention, so the disclosure of relevant data is "imminent."
The relevant person in charge of the Ministry of Land and Resources Administration Hall stated that he had already received Huang Leping’s e-mail and he would respond in strict accordance with the relevant regulations and procedures. How to reply and whether to disclose the details of water quality monitoring should be decided after research.

In May last year, the Ministry of Land and Resources released the 2011 China Land and Resources Bulletin, which announced the results of groundwater monitoring. According to briefings, 57% of the 4727 monitoring sites in the country's groundwater quality monitoring were poor-very poor. Compared with 2010, the total number of water quality monitoring cities with continuous monitoring data is 176, of which, 66% of the city's groundwater quality is dominated by stability, and the proportion of cities with better water quality and water quality deterioration is almost the same.
