The buried fire water supply equipment developed by our company can be placed under public green belts without affecting effective green spaces and saving resources.

　　Integrated commissioning requirements for buried box pumps

　　After the successful installation of fire water supply equipment, the most important thing is debugging. Therefore, we have summarized the following requirements for integrated debugging of buried box pumps and shared them with everyone for backup:

　　1. Before debugging, the size of the fire water tank and the height of the overflow pipe should be checked to calculate the effective volume of the fire water tank

　　2. Before debugging, check that the valves and check valves installed in the pump room are flexible and leak free. The performance of the flowmeter and safety relief valve application special monitoring instruments meets the design requirements. The liquid level gauge indicates reliably and the accuracy meets the requirements

　　3. Before debugging, a water pressure test should be conducted on the piping of the pump station. When the working pressure is less than 1.0MPa, the test pressure should be 1.5 times the working pressure, but not less than 0.6MPa; When the working pressure is greater than 1.0MPa, the test pressure is the working pressure plus 0.4MPa. If the pressure drop does not exceed 0.05MPa within 10 minutes under the test pressure, it is considered qualified. After the pressure test is qualified, the pipeline is flushed until the turbidity of the flushed water is consistent with that of the incoming water.

　　The debugging content and steps related to fire pumps and control cabinets should comply with the current national standard "Technical Specification for Fire Water Supply and Hydrant Systems" GB50974-2014.

　　Underground integrated fire protection equipment (with voltage regulator) electrical control

　　Previously, we provided a detailed introduction to the integrated control system for buried box pumps. However, regarding the electrical control of the integrated fire protection equipment (with voltage regulator) for buried box pumps, what are the differences? Through the following detailed introduction, we can understand:

　　1. The fire pump control cabinet shall be installed in the fire control room of the user's internal type, with a protection level not lower than IP40

　　2. The fire pump control cabinet keeps the fire pump in automatic start mode during normal operation

　　3. The fire pump is guaranteed to operate normally within the specified time after a fire occurs. The time from receiving the pump start signal to the normal operation of the pump is within 2 minutes when it is automatically started

　　4. The fire pump is introduced into the control cabinet through the pressure sensor installed on the water outlet main pipe of the fire pump room and the pressure switch inside the fire pump room

　　5. The fire pump can be manually started and automatically started

　　6. The control cabinet displays the operating status of the fire pump

　　7. The control cabinet has the function of displaying high and low water level alarm signals for water sources such as fire water tanks and high-level water tanks, as well as normal water levels

　　8. Fire water pumps should be equipped with on-site forced start stop buttons and protective devices

　　9. The fire pump control cabinet is equipped with a manual mechanical pump start function and ensures that in the event of a control circuit failure in the control cabinet, personnel with management authority can start the fire pump in emergency situations. When manually operated, the fire pump will work normally within 5 minutes of the alarm

　　10. The front panel of the fire pump control cabinet is equipped with a key device for opening the cabinet door in urgent situations, which should be used by personnel with management authority in emergency situations

　　The incoming and outgoing lines of control cabinet 11 are located at the bottom of the control cabinet

　　Requirements for integrated installation of buried box pumps:

　　The integration of buried water tank and water pump is a high-quality water supply tank. There are many types on the market, and the materials are also different. The integration effect and service life of buried box pumps made of different materials are different, but the integration of buried box pumps has the same reason for liquid cross-linking.

　　In daily life, many people believe that the integration of buried water tanks and water pumps is only a relatively good water storage device.

　　The integrated underground box pump has been launched in the market for nearly five or six years and has been well received by many users. Its installation method is bolt connection buried, which is different from the integration of above ground box pumps, and can be welded and assembled. The integrated buried fire box pump adopts bolt connection method, which can also be divided into two types in terms of overall form: with bottom plate and without bottom plate. The anti floating type without a bottom plate is widely popular nowadays, and today we will focus on introducing this integrated buried box pump.

　　1. The integrated anti floating design of the buried box pump provides better practicality. The weight of anti floating buried water tanks is very light, which can ensure that the water quality of our daily life is clean and rust free. Therefore, the hygiene of drinking water can be guaranteed, and its use is becoming increasingly widespread.

　　2. Using hot-dip galvanized steel plate 3mm and 0.4mm 304/2B food grade stainless steel plate, they are pressed and composite formed by equipment to achieve a tight fit, thereby meeting the requirements of steel plate material strength and stainless steel corrosion resistance.

　　3. Punch the module through the device to meet the assembly requirements of standard modules.

　　4. The manufacturer's installation workers carry out on-site assembly, and the foundation channel steel is treated with 10 # national standard hot-dip treatment. Each beam is combined with a spacing of 1 meter, and so on.

　　5. During the assembly of the buried water tank, Φ 10 * 30 hot-dip galvanized screws and environmental protection, water resistance and anti-aging adhesive strips are used for assembly. After the water tank is assembled, the tie bars and top columns are installed. The reinforcement is made of hot-dip galvanized steel with a diameter of 48, and is installed horizontally and vertically every 1 meter. The top pillar is sealed with 4 hot-dip galvanized pipes of diameter 48 evenly distributed per square meter.

　　6. The installation technicians install the pump room and screws on the outside of the pump room according to the location and size of the pump station. After installation, they inspect and accept to ensure that all screws are tightened without omission.

　　7. Backfill and cover the soil, and prepare the site accordingly.

Can the fire protection box pump integrated buried box pump integrated buried water tank provide fire water supply

　　Secondly, we can see from the setting of the buried water tank why we can confidently say its advantages:

　　1. Water tank material: integrally formed, made of stainless steel plate and carbon steel plate separately molded and stacked. After molding, the four corners need to be welded without any welds, which is not easy to corrode or rust.

　　Internal reinforcement components: hot-dip galvanized steel pipes, criss crossing, to resist the pressure from the covering soil on the top and side walls of the water tank.

　　3. Anti corrosion technology treatment: The outer side of the overall box is treated with anti-corrosion measures to prevent corrosion of the equipment caused by long-term underground moisture and humidity.

　　4. Pipeline: After pipeline fabrication and welding, there will be no running, emitting, dripping, or leaking, ensuring fire safety.

　　5 screws: The screws are hot-dip galvanized, with sufficient rigidity and durability, and will not cause water tank leakage due to breakage, providing higher safety.

　　6. Steel structure: 14 # I-beams are used to reinforce the interior of the pump room to resist pressure from the top and surrounding areas.

　　7. Ladder Setting: The staircase adopts a combination of steps, which facilitates personnel to enter for maintenance and after-sales service.

　　8 Installation process: The buoyancy problem encountered in the integration of buried box pumps is due to the accumulation of water around and at the bottom of the pump station, which causes significant buoyancy on the pump station. One end of the pump station tilts up, resulting in deformation and tearing of the water tank, which no longer exists. The anti floating foundation design connects the side plate to the overall foundation, and no matter how strong the buoyancy is.
