Installation steps for integrated underground box pump station

Dongyang, Zhejiang Province, is a prefecture level city under the jurisdiction of Jinhua City. It is known as the "Wuzhiwang County" and "Songshan Huashui", and is known as the hometown of education, architecture, and arts and crafts. There are over 260 Ming and Qing Dynasty ancient architectural complexes in Dongyang Market that integrate wood carving, brick carving, stone carving, and painted art, and are praised by domestic and foreign experts as "cultural and artistic heritage of international level". The Hengdian Film and Television City is located here.

The buried box pump integrated pump station belongs to the series of automatic constant pressure water supply equipment for fire protection. It adopts a new and mature AC motor stepless speed regulation technology to achieve variable frequency constant pressure water supply, solving the problems of large space occupation, easy water pollution, high infrastructure investment, especially the inability to maintain constant water pressure, which leads to local equipment not working properly in traditional water supply methods. This product is divided into two types: above ground fire intelligent variable frequency constant pressure integrated water supply equipment, and underground fire intelligent variable frequency constant pressure integrated water supply equipment.

The following is an integrated pump station with buried box pumps, replacing concrete water tanks. The following are various design institute drawings and models, and the following are installation and construction drawings. The company has construction cases in various parts of the country.

Installation steps for integrated underground box pump station:

The use of variable frequency control technology to achieve variable frequency constant pressure water supply has a more significant energy-saving effect compared to traditional regulating valves for constant pressure water supply (which can be calculated based on detailed conditions)

Advantages of integrated pump station with buried box pump:

● Compliant with GB50794-2014 Fire Protection Code: The motor of this product's fire pump is installed in a dry manner, which meets the technical specifications for fire pump motors in the "Technical Specification for Fire Water Supply and Hydrant Systems" implemented in October this year;

● Energy saving: The energy-saving control software used enables the water pump to achieve maximum energy-saving operation;

Water saving: Based on practical water usage conditions, the pressure of the pipeline network is set, and the water pump output is automatically controlled to reduce water leakage and seepage;

● Reliable operation: The soft start of the pump is completed by the frequency converter, enabling the pump to switch from power frequency to frequency conversion without impact, avoiding pipeline impact, preventing pipeline pressure from exceeding the limit, and preventing pipeline rupture;

● Multiple control modes: segmented water supply, timed water supply, and manual selection;

● Automatic alarm and intelligent start: If an abnormality is detected in a certain pump, the system will send an alarm message to the upper computer and start the backup pump to maintain the balance of supply

Extended service life: Due to the reduced uniform speed of the pump, the service life of the pump and valves can be extended;

● Can eliminate the water hammer effect during start-up and shutdown;

With the rapid development of our country's economy and people's continuous pursuit of quality of life, land has become increasingly valuable. Our company has developed an underground fire water supply equipment that can be placed under public green belts, which not only does not affect the effective green area, but also saves resources.

The buried fire integrated water supply equipment includes a water tank and a pump room, which are easy to maintain and operate stably and reliably. It's an underground concrete poolAlternative products. Low cost, does not occupy ground area, can be placed in the owner's open space, under the green belt, or in scattered open spaces. Made with anti-corrosion grade, durable and long-lasting. Capable of producing a volume of 12-1200 cubic meters. The lift can reach up to 100 meters.

The advantages of buried fire integrated water supply equipment are as follows:

1. Space saving: The water pump and pump chamber are placed in the water tank and fixed on a dedicated module for the integrated pump station. Normally, it only occupies a water tank capacity of 0.5-1.5m.

2. Easy to move and disassemble, long service life: Due to the use of prefabricated stainless steel water tanks, the previous welding method has been changed, and screw assembly is adopted, which has strong applicability, easy installation, and does not require specialized equipment.

3. Easy emptying: Due to the use of a new type of submersible fire pump, it can be directly submerged in water without the need for special air discharge. As long as the water tank level is within the specified level, it can directly enter the fire water supply state.

4. Frost free cracking: The fire pump is hidden deep in the water tank and will not be burned out due to freezing in winter.

5. Low noise: Equipped with a water immersed motor and water pump, it greatly reduces the operating noise.

6. Reliability: Water immersed motors will not burn out the motor or corrode the motor bearings due to rain or environmental temperature.

7. Easy to upgrade: with interfaces to support remote transmission, automatic cleaning, sterilization, and disinfection.

Dongyang has a long history. In 195 AD (the second year of Xingping reign of Emperor Xian of the Eastern Han Dynasty), the county system was established, and it has a history of more than 1800 years. Known as "Wuzhiwang County" and "Songshan Huashui". Geography is known for its appearance of "three mountains sandwiching two basins, two basins enclosing two rivers"; Culture, education, culture, and culture have long been renowned as the hometowns of education, architecture, arts and crafts, and dinosaurs. In recent years, due to the discovery of dinosaur eggs in scientific research, it has also been known as the "hometown of Chinese dinosaurs". Belonging to the Yangtze River Delta Economic Region, it is an approved city for opening up to the outside world and a historical and cultural city in central Zhejiang. Dongyang boasts a rich cultural heritage and numerous talented individuals, giving birth to the renowned Northern Expedition general Jinfozhuang.
