Categories: 1) Equipment by application range is divided into: Fire private automatic constant pressure water supply equipment 2) equipment by the fire pump control mode is divided into:. A constant-frequency automatic fire water supply equipment constant pressure water supply automatic fire b frequency devices NOTE: automatic fire frequency constant pressure water supply equipment including: Fire regulator for constant pressure, fire work-frequency transformer of automatic water supply equipment, fire-frequency range of the regulator for the regulator, the fire service for automatic constant pressure water supply equipment and Fire regulator and the fire service are automatic constant pressure water supply equipment. Design choice points: 1) the overall structure of the layout and component mounting location of the device should be reasonable, leaving room for maneuver with the installation and maintenance. 2) supporting the use of purchased parts, equipment, and materials should be selected in line with national standards (the industry standard) products, and should have the necessary technical documents, including certificate, manual, test reports. 3) instrumentation supporting the use of its range and accuracy should be a reasonable choice in the normal use position. Supporting the use of valves, fittings, pressure rating should be used reasonably. Structure 4) pump unit shall comply with the requirements of the relevant provisions of GA 30.1. 5) Fire and Life (production) shared device must have a separate outlet fire. Pipeline 6) devices should be set safety valve opening pressure of not more than 1.1 times the maximum working pressure. 7) pressure tank shall comply with the relevant provisions of 30.1 of GA. 8) capsules shall GA 30.1 relevant regulations. Construction, installation points: 1), pressure tank automatic fire water supply equipment constant pressure, the volume, pressure, water level and pressure shall meet the design requirements. Installation 2), automatic fire safety valve on the water supply equipment constant pressure, pressure gauges, vent pipes, water level indicators, etc. shall comply with the requirements of the product manual. 3), fire automatic constant pressure water supply equipment installation location, the inlet and outlet should be directed to meet the design requirements; it should be located around the Access installation, the width of not less than 0.7m, top fire pressure water supply equipment to the floor or beam bottom distance of not less than 1.0m. 4) equipment to the scene to be unpacking inventory. In place to be leveling grout. Piping and electrical control wiring required to connect the control drawings, check and correct. 5) After installation, commissioning and commissioning of the equipment required. Including pump start and stop control, each valve switching, and equipment cleaning, water-filled after commissioning.
