Underground fire pump station, prefabricated fire box, pump integrated underground installation

Description :

Underground fire pump stationThe prefabricated box pump integrated pump room houses supporting equipment such as control cabinets, dehumidifiers, and fire pumps. The pump room adopts 24-hour passive ventilation, is equipped with drainage facilities, and is coated with thin fireproof coating to meet the fire resistance level of Grade II. We use industrial grade dehumidifiers that operate fully automatically to ensure dryness inside the pump room; The water pump adopts a vertical pump, which is installed in a dry manner for easy maintenance. It adopts a self-priming suction method and meets the requirements of relevant specifications; The control cabinet strictly follows the requirements of the new consumer standard GB50974-2014, and is equipped with dual power supplies. The operating data can be recorded and called. The pipelines and valves are connected by clamps, which are easy to install and can be used by connecting the water outlet. The accessories meet the standards.

　　Selection of integrated non floating pump station for buried fire pump station: 1. The model of the fire pump unit is determined 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 140% of the system design pressure; 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. The fire water tank calculates 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 individual fire water supply system in the engineering project. When a construction project consists of multiple fire water supply systems, the total amount of water used for extinguishing a single fire is 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 determined based on the tank volume and the actual situation on site. 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. A sliding rail type top cover should be added to the top of the maintenance port for easy opening and closing; 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.
