Description

Technical Field

[0001] The invention relates to the field of sewage pump station vocational training, and in particular to an electrical operation platform and training method for a pump station. Background Art

[0002] The rainwater and sewage pumping station plays an important role in urban flood control and drainage, and sewage transportation. However, there is a lack of professional and technical personnel in the operation and maintenance of pumping stations in the society. We can find that the main reasons are as follows:

[0003] 1. Rainwater and sewage pumping stations are municipal facilities and are generally managed by relevant municipal units. There are not many such units and they belong to a niche industry, so there is a shortage of corresponding technical personnel in society.

[0004] 2. The construction cost of rainwater and sewage pumping stations is relatively high, and there is no professional practical training platform on the market, so there are few opportunities for such professional and technical personnel to learn and practice. 3. The operation and maintenance of rainwater and sewage pumping stations involve water pumps, high and low voltage power distribution systems, screen machines, valves and other professional equipment, which are highly comprehensive and professional.

[0005] In order to solve the current shortage of professional and technical personnel in this industry, it is particularly important to develop a pump station operation platform with high cost performance for technical personnel to practice and train.

[0006] This subject aims to cultivate drainage pump station operation and management talents and equipment inspection and maintenance skilled craftsmen. Combining electrical, mechanical, automation, pump station operation and management and other majors, a pump station practical training platform has been developed, which enables one platform to carry out pump station practical operations, basically covering all pump station operation operations and pump station routine facility maintenance operations. Pump station facilities such as diesel generator sets, low-voltage inlet and outlet distribution cabinets, pump pool water tanks, gantry cranes, etc. are set up to realize generator power supply and switching operations, pump station automatic control and water pump manual start and stop operation operations, water pump fault inspection and repair operations, and downhole operations.
