Newly designed prefabricated BDF box pump integrated fire pump station

The construction period of concrete fire water tank and pump room is long, and it is prone to common quality problems during construction, such as easy infiltration, heavy self weight, difficult structural treatment, large footprint and space, and high cost; If the space is utilized as a parking space, it can create considerable economic benefits. Due to inadequate management or lack of attention, it is difficult to ensure that the fire-fighting equipment system is always in normal condition. Once a fire occurs, it can cause significant losses. The prefabricated box pump integrated fire-fighting water supply pump station effectively solves this problem.

Underground water tanks are favored by users due to their small surface area, corrosion resistance, and low cost. In fact, when buried water tanks are deep underground, it is easy to encounter situations such as groundwater leakage or self leakage due to tank damage. As the entire water tank is buried underground, when leakage occurs, the leaked water will generate buoyancy, lift the water tank, and cause damage to the water tank. Therefore, the design of anti floating buried water tanks is very necessary for buried water tanks.

The three common overall anti floating methods for buried water tanks are: increasing the pressure weight, using anti floating anchor rods, and using anti displacement piles. Underground water tanks often use anti floating piles to resist floating. Anti pull pile, also known as anti floating pile, is a type of pile that can withstand tension. Ordinary anti floating piles also transmit force from the top to the bottom of the pile, and the magnitude of the force on the pile changes with the groundwater level. Anti pull pile refers to various types of piles that resist upward displacement of buildings. Unlike general foundation piles, anti pull piles have their own performance.

Newly designed prefabricated BDF box pump integrated fire pump stationCorrect order:

1. Earthwork excavation: Confirm the order and slope of excavation - excavate in sections and layers evenly - trim and clear the edges and bottom.

2. The outer side of the box is coated with epoxy coal tar roller coating, with a thickness of 2-3mm.

3. The fastener adopts two layers of epoxy zinc rich primer and two layers of epoxy glass flake surface coating.

4. Pressure test: Manually start each water pump separately, test the pressure at 1.2 times the set pressure for 15 minutes, and set the pressure relief value of the safety relief valve at 1.1 times the design pressure.

5. Grounding: All equipment must be grounded.

6. The soil covering around the pump station shall be uniformly compacted layer by layer every 500mm, and the top plate shall be compacted using a frog or plate vibration compactor. The soil covering shall be 1.0m deep

7. Determination of slope: The excavation slope of this project is determined according to the local soil conditions.

8. The outlet pipe, sewage pipe, inlet pipe and external pipeline of the pump station are connected by flanges.

9. Water testing: After the installation of the pump station is completed, inject water for 24 hours.

10. Connect the dual power supply to the PAE dual power control cabinet.

When designing an underground water tank, it is necessary to clearly analyze the anti buoyancy and buoyancy. The anti buoyancy design should be calculated based on the anti buoyancy design water level issued by the geological report. The advantage of the anti buoyancy water level will affect the selection of the foundation form. The integrated pump station of buried box pumps solves the problem of water tanks occupying a large amount of land. Buried underground, the ground can be used as a parking lot or greening.

The buried box pump integrated fire constant pressure water supply pump station is composed of pipeline system, water tank system, water pump system, control system, etc. The water tank system primarily consists of a water tank and a manhole; The pipeline system mainly consists of inlet pipes, fire water pipes, electrical contact pressure gauges, and various valves; The water pump system mainly consists of submersible multi-stage fire pumps and pump rooms; The control system primarily consists of a fire intelligent control cabinet, an air pressure tank, and a control room. The silent check valve is connected to the pump chamber with bolts for sealing, and the pump chamber is also connected to the control room with bolts for sealing. The water pump system is placed in the water tank, and the control room and water tank are planned as a whole. Its characteristic is that there is an electric contact pressure gauge on the fire pipeline; The intelligent boosting and stabilizing control cabinet for fire protection is equipped with a processing controller. After adopting the above plan, the water pressure in the fire pipeline was stabilized, the integration of the box pump was processed, space was saved, the service life of the water pump and motor was extended, and the fire protection effect was ensured.
