Underground integrated fire booster water supply equipment

Description :

Underground integrated fire booster water supply equipmentIt is the second generation new product independently developed by our company, referred to as the intelligent pump station. It is an international first invention, a high-tech crystallization, a national patent, and has passed the testing machine of the National Fire Bureau

　　Construction testing. This product is composed of an assembled composite stainless steel water tank and fire water supply equipment.

　　Equipment selection

　　1. Water pump unit

　　Determine the model of the fire water pump based on the design flow rate and required fire water supply pressure of the fire water supply system in the engineering project. The water pump should be one in use and one as backup, and the pressure at zero flow should not exceed the system design pressure

　　140%; When the system flow rate is 150% of the rated flow rate of the water pump, the pressure should not be lower than 65% of the rated pressure.

　　2 Fire water tank

　　Calculate the required fire extinguishing water consumption for each individual fire water supply system based on the fire design flow rate and fire duration of each system in the engineering project. When a construction project consists of multiple fire water supply systems

　　At that time, the total amount of water used for extinguishing a fire was the sum of the water used for extinguishing each individual system. From this, the effective volume of the fire water tank is determined, and the size of the fire water tank can be based on the tank volume and combined with the actual situation on site

　　It depends on the situation.

　　The width of the main passage in the pump room should not be less than 1.2m, and the width of the passage in front of the electrical control cabinet should not be less than 1.5m. A 2m × 2m maintenance port should be set at the top of the pump room, which should be at least 200mm above the ground, and a sliding rail top should be added to the top of the maintenance port

　　Cover, easy to open and close; Install escalators in the pump room for easy access; Ventilation pipes should be installed at the top of the pump room, with a height of at least 1.5m above the ground. The new concept uses reinforced concrete slab foundation 401 instead of the bottom of stainless steel water tank 1

　　The board not only saves the material of the bottom plate and eliminates the installation process of the bottom plate, but also completely avoids the effect of groundwater buoyancy on the bottom plate of the water tank, and eliminates the leakage of the box bottom plate, overcoming the disadvantage of long construction period

　　On the end, it saves raw materials and human resources, and also increases the strength of the bottom plate.

Underground integrated fire booster water supply equipmentBased on multiple practices, experiments, and research, our company has redesigned the traditional buried fire water tank and explored a new approach to resist groundwater buoyancy. I

　　By eliminating the bottom plate of the water tank and using the structure of connecting the side plate of the box to the reinforced concrete foundation, not only is the buoyancy effect on the box completely eliminated, but the bottom plate of the box has no leakage point and is easy to install and engineered

　　Short cycle, saving manpower and material resources. There are three key points to implementing this technical solution:

　　One is to establish a comprehensive integrated non floating pump station system, which includes various parts such as stainless steel water tanks, fire hydrant pump rooms, sprinkler pump rooms, channel steel profiles, connecting bolts, pits, and embedded bolts;

　　The second approach is to consider the pit as a whole, consisting of a side wall foundation, a reinforced concrete slab foundation at the bottom, and a sand and gravel cushion layer placed under the reinforced concrete slab foundation; The third is to install the fire hydrant pump room and sprinkler pump room

　　Tighten the embedded bolts embedded in the reinforced concrete slab foundation to the reinforced concrete slab foundation and place it in a stainless steel water tank. This structural design has several obvious features: firstly, the stainless steel water tank is made of

　　Composed of top and side panels; The second is that the channel steel profile is connected to the bottom surface of the four wall side plates of the stainless steel water tank through connecting bolts, and a rubber sealing strip is provided between the two;

　　Thirdly, there is a concave rectangular plane on the reinforced concrete slab foundation, which is longer than the length of the stainless steel water tank and wider than the width of the stainless steel water tank; The third is to fasten the steel bars under the channel steel profile with embedded bolts

　　The foundation of the concrete slab is recessed into the plane, and a rubber sealing strip is provided between the two; The fourth is that there is sealant filled between the concave plane and concave side of the reinforced concrete slab foundation and the channel steel profile, and the sealant is

　　Silicon copper sealant or silicon steel structural adhesive; The upper end of the pre embedded bolt connecting the groove steel profile and the concave plane of the reinforced concrete slab foundation is submerged in the sealant.
