Recently, the "General Contracting Project of Boiler Feed Pump Frequency Conversion Technology Transformation Project of Yili Power Plant of Guoshen Group" undertaken by Hope Sunland has been successfully implemented and connected to the grid, adding another classic to the comprehensive application of Sunland's high-power boiler feed pump.
2020 has been an extraordinary year. All walks of life have been affected by the epidemic, but the people of Senlan have not flinched. In the stage of fighting the epidemic, the Sunland project team resolutely went retrograde to serve customers and arrived at Dalat Banner Yili Industrial Park to carry out work. During the transformation process, the project team adhered to high standards and strict style, strictly implemented the relevant rules and regulations of Guoshen Group, and conscientiously completed various tasks. Whether it is civil construction, locomotive transformation, or even multidisciplinary comprehensive engineering operations such as thermal control and waterways, we have kept improving, successfully completed the tasks assigned by the owner, and successfully created another excellent project of the water pump EPC project.
The inverter of this project adopts the special high-pressure inverter of Sunland SBH series feed pump, which is successful from installation to commissioning, which ensures the smooth start of the unit, and the energy-saving effect reaches more than 20%, which meets the comprehensive index requirements of reducing the power consumption rate of the power plant by 0.5%, and has been highly recognized by the power plant users!
Shenhua Yili Power Plant was built in 2006 and is located in the Yili Chemical Industry Park of Dalat Banner in Inner Mongolia, which was the largest coal gangue power plant in China at that time. The boiler is the first 200MW circulating fluidized bed boiler without external bed with independent intellectual property rights in China; The steam turbine is also the first 200MW double-cylinder double-exhaust steam pure condensing direct air-cooled steam turbine in China.
The successful commissioning of Guoxin Yili project once again proves the achievements of Senlan in the intensive work of the power industry. For thermal power generation, as the core industry of national power energy, Hope Senlan has been serving and exploring as a key industry for many years, and the comprehensive application and transformation of feed pumps has achieved the transformation performance of dozens of large-scale thermal power generating units, which has won the unanimous recognition of the industry. In the future, it is hoped that Senlan will continue to provide better energy-saving solutions, products and services for the thermal power industry, and make greater efforts for national energy conservation and consumption reduction.

Sunland inverters are designed for environmental requirements
1. The ambient temperature ---- is generally "-10-+40°C"; Derating between 40 and 50°C, the additional output current must be reduced by 1% for every 1°C increase. If the ambient temperature is too high and the temperature changes greatly, the insulation of the inverter will be greatly reduced, which will affect the life of the inverter.
