How to arrange the plane of integrated prefabricated pump station

The integrated prefabricated pump station is the power source to solve the problems of drainage and irrigation, water supply and water resource allocation under the condition of no gravity flow. With the acceleration of national infrastructure construction and urbanization process, the traditional concrete pump station has increasingly exposed its own shortcomings that are difficult to overcome. The pump station is a buried installation. The main body of the pump station is composed of acid and alkali resistant fiberglass shaft, specially designed sewage pump, coupling device, pipeline, special valve, liquid level sensor, GPS remote control system, grid and ventilation system. The utility model has the advantages of convenient installation, reliable quality, less civil work and low cost, which can be used as the substitute of small and medium-sized concrete pump station and rural sewage transformation application. Next let's learn the layout of the pump station and its operation, commissioning and maintenance!

The plane layout of pump station shall meet the following requirements:

1. The plane layout of the submersible self coupling water pump can only meet the requirements of water pump installation and hydraulic flow state without considering the maintenance space of the water pump;

2. For dry installed water pump, the plane layout shall consider the requirements of water pump installation and water pump suction pipe flow pattern;

3. When the water pump is equipped with air-cooled motor, the plane layout of the pump station shall also meet the heat dissipation requirements of the water pump;

4. The plane size and layout of modular wet well pump station shall meet the installation, lifting and daily operation requirements of main equipment such as water pump and grid;

5. The plane size of the wet well of the modular integrated pump station shall meet the requirements of the flow pattern of the water pump suction pipe, the installation, lifting and daily operation of the grid;

6. The plane size of the dry well of the modular integrated pump station shall meet the requirements of the installation, heat dissipation, maintenance and daily operation of the water pump and control cabinet;

7. The modular integrated pump station shall be equipped with sump and drainage pump in the dry well to drain the water in the well;

8. The control cabinet can be installed in the dry well of the pump station or on the ground. If it is installed in the dry well, ventilation, heat dissipation and dehumidification shall be considered;

9. When the pump station adopts a combination of multiple shafts, the plane layout shall meet the requirements of the overall installation and operation of the pump station, and the same model and number of pumps shall be installed in each shaft.

Operation and debugging:

The commissioning of integrated prefabricated pump station shall meet the following requirements:

1. All fixed connection parts shall be fastened.

2. The rotor and all moving parts shall operate normally without abnormal noise and friction.

3. The auxiliary system operates normally, and the pipeline connection shall be firm without leakage.

4. The safety protection, electric control device and instruments of each part of the pump shall be sensitive, correct and reliable.

Operation and maintenance:

1. Appropriate guardrails shall be erected outside the pump station, warning signs and warning signs shall be placed to warn non staff not to enter the pump station area, so as to avoid personal injury accidents.

2. The top cover of the pump station shall be locked to prevent others from opening and entering.

3. In the process of daily maintenance and operation, if electrical operation is involved, it must be carried out by personnel with electrical operation qualification certificate.

4. In the process of daily maintenance and operation, if personnel enter the pump station, they must comply with the safety regulations for well (pool) operation.

5. In the process of daily maintenance and operation, relevant safety articles and labor protection articles shall be carried, such as safety belt, safety helmet, etc.

6. When entering the pump station barrel for maintenance, safety protection measures shall be taken. The anti poison appliance must be calibrated before use and can only be used after it is qualified.
