The prototype of the CAP1400 factory water pump jointly developed by Xiangdian Electric's long pump and the Shanghai Nuclear Engineering Research and Design Institute under the Hunan Electric Power Co., Ltd. (600416.SH) passed the China National Machinery Industry Federation’s national experts to witness the development of the project. The electric long pump has passed the national appraisal of the CAP1400 pump and Tianwan nuclear 3rd-axis pump this year, and another result of nuclear power product development.
The project is a national major science and technology special project for large-scale advanced pressurized water reactor nuclear power plants. It was developed in August 2012. The length of the bottom of the prototype pump suction bell to the top of the motor is more than 20 meters. It is the longest vertical long-axis pump in China. The level of technology is leading domestically.
At the prototype test site witness meeting, Zhou Hong, the general manager of Xiangdian Long Pump, led the R&D team to report on the prototype development process and related test reports. Experts from SINA, CGNPC, CNNC, and other single λ witnessed the performance test of prototypes, and reviewed the prototype hydraulic performance tests and 200-hour durability tests. Unanimously agreed that the test results meet the "plant water pump development task book" requirements.

Bottom layer communication: M-BUS/485 collector and measurement meter transmit data by M-BUS/485 line with 4 channels, and can connect the meter according to any topological structure. Build in backup battery, could works for 48 hours normally, and the data can be saved for 10 years if power is cut off.
Middle layer communication: Middle layer communication means the communication between the concentrator and collector. This communication is by wireless RF way, no need of communication line. The wireless communication distance between the concentrator and collector can be about 3km at wide open area.
Upper layer communication: Communication methods indicate below can be selected between concentrator and management center:
(a) GPRS Communication Mode
(b)Telephone Line Communication Mode
(c) RS232 Communication Mode
(d) Ethernet Communication Mode
