Introduction to Underground Fire Constant Pressure Water Supply Equipment:

The integrated pump station of the fire constant pressure tank pump adopts BDF material, and the inner side of the tank body adopts food grade SUS304-2B stainless steel material. It is an intelligent integrated structure of the tank pump, consisting of an assembled water tank and an integral pump room. The pump room of this system is independently set up and can integrate multiple functions according to customer needs. For example, a single system pump station can be made into a fire hydrant water supply system, etc; The dual system pump station can integrate fire hydrant water supply and automatic sprinkler system into one; The three system pump station can integrate the fire hydrant water supply, automatic sprinkler, and fire cannon fire extinguishing system into one. The entire system can evolve into multiple types and sizes, providing users with diverse choices. Since the release of GB50974 "Technical Specification for Fire Water Supply and Hydrant Systems" in October 2014, the use of "fire constant pressure equipment" has been prohibited and all have been replaced with "fire booster water supply equipment". Therefore, all pump stations produced by our company now adopt booster control.

Manufacturing process of buried fire constant pressure water supply equipment:

The material of the water tank can be divided into hot-dip galvanized steel plate, stainless steel plate, or composite plate according to customer needs. The manhole adopts a sliding rail type manhole, and the ventilation adopts a 24-hour non powered ventilation cap. The structural form adopts a steel structure form. Adopting a combination of bolt assembly and welding for assembly. The internal structure and material of the pool are full scaffold structure or portal steel frame structure; Hot dip galvanized steel pipe or composite plastic profile material; The internal structure and material of the pump room are portal steel frame structures; The material is hot-dip galvanized I-beam or composite reinforced I-beam; Use C15 concrete to make a cushion layer with a thickness of 150mm; cover the cushion layer with C30 impermeable reinforced concrete and level it. The size of the foundation shall not exceed 1000mm on each side compared to the size of the pump station. The thickness of impermeable reinforced concrete is 500mm. An emergency drainage system shall be installed in each pump room, and the emergency sewage pump of the system shall consist of one large pump and one small pump. Small pump WQ20-15-1.5, large pump WQ100-15-7.5. The collection pit is reserved during the basic production, and its size is designed to ensure a flow rate of 5 minutes of water entering the pool; If the size of the collection pit is not sufficient, the design should ensure that there is no more than 100mm of sewage in the pump room and raise the foundation height of the water pump and control cabinet.

Application scope of buried fire constant pressure water supply equipment:

1. Domestic and fire-fighting water for ordinary residential buildings, commercial and residential buildings, office buildings, residential communities, government offices, hotels, schools, etc.

2. Fire water supply for industrial and mining enterprises.

Highlights of Underground Fire Constant Pressure Water Supply Equipment:

1. No welding required - all templates, steel structure skeleton, and accessories are connected by hot-dip galvanized bolts, thus avoiding the disadvantage of difficult anti-corrosion treatment and easy rusting after welding;

2. Long service life - all load-bearing components are made of hot-dip galvanized and SUS304-2B stainless steel materials, and all are assembled without welding. The sealing material is EPDM (ethylene propylene diene monomer) rubber. The exterior of the pool is coated with epoxy coal tar for corrosion prevention. The interior and exterior of the pool are protected against corrosion with a double-layer coating (asphalt layer+outer hot-dip galvanized layer+inner hot-dip galvanized layer+stainless steel layer). If the galvanized layer is damaged during transportation or installation, epoxy rich zinc+epoxy glass flakes are used for severe corrosion protection. Therefore, the service life is over 70 years;

3. Short installation cycle - the installation of the large water tank should not exceed 30-50 days;

4. No leakage - EPDM (ethylene propylene diene monomer) rubber sealing material is used for the gap between templates;

5. Competitive price - comparable to the cost of reinforced concrete water tanks, even saving 30%

6. Large specifications - can assemble water tanks (pools) of 1-20000m3 or even infinite size according to user needs.

7. Good hygiene effect - because the inner side of the pool body is made of food grade SUS304-2B stainless steel material;

8. High strength - The product structure design is designed by steel structure engineers from the design institute, and the top pressure and lateral pressure are calculated at 100kN/㎡ and without water; The top pressure and lateral pressure are transmitted to the box body and then to the steel structure skeleton inside the box body.

9. Energy saving and environmental protection - this product can be reused and regenerated, according to current national environmental standards;

10. Service - The raw material quality of this product is strictly inspected according to national standards, and installation is strictly carried out according to enterprise standards, so there is no need for after-sales service.

11. Convenient: According to the on-site drilling of the construction unit, and the connection of the pipe can be made without welding; .

Material selection for integrated constant pressure water supply equipment of buried box pump:

The material selection for the integrated pump station of the constant pressure tank pump is MXF template (made of hot-dip galvanized steel plate and stainless steel plate composite molding), rubber sealing material, steel structure skeleton, and component assembly. All load-bearing components are made of hot-dip galvanized (galvanized layer ≥ 8 wires, in accordance with the standard "Galvanized Pipe" GB/T3091-2008) and SUS304-2B stainless steel materials, and all are assembled without welding. The sealing material is EPDM (ethylene propylene diene monomer) rubber. The exterior of the pool is coated with asphalt for corrosion prevention (in accordance with the standards "Technical Specification for Coating Corrosion Prevention of Petrochemical Equipment and Pipeline" Sspan022 and SH/T0098-1991 (1998) "Pipeline Anti Corrosion Asphalt"). The interior and exterior of the pool are coated with a double-layer anti-corrosion coating (asphalt layer+outer hot-dip galvanized layer+inner hot-dip galvanized layer+stainless steel layer).
