When the distance between the pump station barrel and the edge of the foundation pit is less than 1 m but more than 0.5 m, only graded sand and gravel can be used for backfilling, and the gravel particle size shall not exceed 32 mm. When backfilling in winter and rainy days, check whether the backfill materials are stuck together. The backfilling of the foundation pit shall be carried out continuously and completed as soon as possible. During the construction, the ground water shall be prevented from flowing into the foundation pit to avoid slope collapse or damage to the foundation soil. Backfilling shall be carried out in layers. The height difference of each layer shall not exceed 50cm. It shall be compacted with a tamper or manually, and the compaction shall be more than 90%.

Handrails are made of 304 stainless steel or 316 stainless steel. 5. The control cabinet can be made of 304 stainless steel or 316 stainless steel, which is the core of intelligent control. 6. The flange is made of 304 stainless steel. 7. Check valve, with various stainless steel materials, such as 304, 201, 316, etc. 8. Gate valve is made of 304 stainless steel, or 201, 316, etc. 9. The grating support is made of 304 stainless steel. Similarly, 316 stainless steel can also be selected.

1. To ensure the safety of the pump room, the pump room must be locked. 2、 Constant pressure water supply integrated pump set Manufacturer Safety Operation Regulations, Hygiene and Safety Management System for Secondary Water Supply, Patrol Inspection Specifications, Water Quality Inspection Record System must be posted inside. 3 large Constant pressure water supply integrated pump set There must be the following record documents inside: Patrol Inspection Record, Water Tank Blowdown Record, Disinfection Record, Water Quality Inspection Record. 4. The pump room must be marked with the pressurized area, and the corresponding control system should also be marked with the pressurized area: low area, middle area, high area, etc, Mark the product model, qualified number, ex factory date, etc. 6. Water pump identification: the number of pumps must be painted on each pump; For example: 1 # pump, 2 # pump, 3 # pump, 4 # pump, 5 # pump, words. 7. "Normally open" signboard of inlet and outlet valves; 8. The pipe shall be marked with water flow direction arrow; 9. The prefabricated energy-saving pump room needs a drainage system 10. The energy-saving pump room can realize on-site control and remote monitoring;

Constant pressure water supply integrated pump set Manufacturer General provisions: equipment discharging heat, steam or harmful substances, large Constant pressure water supply integrated pump set Local exhaust should be adopted. When local ventilation can not be used or local ventilation can not meet the health requirements, it shall be supplemented with all-round ventilation or adopt all-round ventilation. The air distribution design shall be optimized according to the characteristics and changes of pollutants, and the normal operation of local exhaust system shall not be damaged. At the same time, when releasing waste heat, moisture and harmful substances, the ventilation volume in all aspects shall be determined according to the large air volume required. When the quantity of harmful substances cannot be determined, the ventilation volume in all aspects can be determined according to the ventilation frequency. All kinds of pump rooms in the domestic sewage treatment station should adopt natural ventilation. When mechanical ventilation is adopted, indoor air should not be recycled. All pump rooms in the oily sewage treatment station should adopt natural ventilation. When mechanical ventilation is adopted, indoor air should not be recycled, and the ventilator and motor should be explosion-proof and directly connected.

Constant pressure water supply integrated pump set Manufacturer It is of great significance to use light weight and small volume FRP materials, adopt integrated structural design, and occupy a small area, effectively relieving the current situation of land resource tension. During the design and development of the pump station, advanced innovative ideas were introduced to provide people with high-quality life services. large Constant pressure water supply integrated pump set On the premise of liberating human resources, it has realized the treatment of domestic sewage and rainwater, and the sewage treatment effect is also very good. On the premise of ensuring the functional requirements of the pump station, the impact of the construction and use of the pump station on the surrounding environment is minimized, which effectively promotes the promotion and application of the pump station.

In recent years, with the construction of more and more pump houses around the country, problems related to them have become increasingly apparent, Constant pressure water supply integrated pump set Manufacturer Management and maintenance, water pollution, safety management and other issues are gradually exposed. How to further strengthen the management level of the above pump room facilities and equipment, further improve and ensure the safe water supply capacity, and manage and maintain all kinds of facilities and equipment in the pump room has become the common concern and work direction of all major water supply management enterprises and water supply equipment manufacturers. Standardized standard pump room construction and management introduced, large Constant pressure water supply integrated pump set Mainly based on the optimized configuration and construction of various facilities and equipment in the pump room, the computer network information technology is used to organically integrate various nodes in the pump room. At the same time, in combination with the local economic construction level, according to the actual situation and budget needs of the project, a reasonable standardized construction, management and maintenance scheme is provided and implemented for various pump rooms. Its core is the safe full frequency conversion control pressurization equipment, followed by the integration of computer network information system, and the safety management and maintenance of the whole life cycle.
