1. No pumping station: water pump and the pump chamber is placed in underground tanks, pumping stations and fixed in the integration of the Ministry of items, only with a tank capacity of 0.5m3 ~ 1m3. 2. Resistance to use: a combination of stainless steel water tank BDF assembled without welding, buried no oxidation, hot-dip galvanized cabinet plus bitumen spray corrosion, high strength, long life, no rust, no leakage, easy installation. 3. Easy emptying: This product is the use of submersible fire pump, submersible directly on the water, no air emissions, no cavitation. 4. No risk: Integrated Pumping integrated buried in the ground, to avoid the reinforced concrete underground pumping station frequently flooded during the rainy season pond leakage or other accidents. Submersible pumps are also not because the air is humid motor insulation performance degradation, causing the device leakage, can not enter the fire condition. 5. anti-cracking: diving fire pump placed in the depths of the tank, water tank buried in the ground 60 ~ 80cm or less, will not freeze in winter, the water pump is not cracking. ① mechanical flushing head and ion rods at the top of the tank uniform (usually meet with a volume of 25 cubic meters of water tank) Definition: the pressure tank, pump, control cabinets, control instruments, pipe fittings and other components of the body by its pump motor and pump two parts. Pump structure includes parts, pump and motor coaxial pump body, impeller, pump cover, mechanical seals. The axial force of the pump impeller balance ring to set the balance. Pump inlet and outlet on the same horizontal axis, and the specifications of the same caliber. There pump mounting base, easy to install, increasing the stability of pump operation. Features: booster pump seal mechanical seal with reliable sealing, no leakage characteristics. Typically used for fire control network end of pressurized water supply equipment. Categories: 1) equipment for the fire water system is divided according to:. A Fire Hydrant System Fire booster regulator water supply equipment b sprinkler system fire booster regulator c hydrant water supply equipment and sprinkler systems combined with increased fire protection. Pressure regulator water supply equipment 2) equipment divided by the installation location:.. a top-mounted fire booster regulator b supply equipment mounted under fire booster regulator water supply equipment 3) equipment set by the pressure tank is divided into:. a vertical Water tank fire booster regulator device b horizontal tank fire booster regulator water supply equipment c qi firefighting water supply equipment d booster regulator capsule fire booster regulator water supply equipment design choice points: 1) Pressure tank manufacturing units should hold pressure vessel manufacturing license or registration book, and have a sound quality management system and the system. Purchased fittings 2) equipment shall have a product certificate and by the admission after passing inspection before use. Component parts pressure tank equipment, water pumps, electrical components, etc., should be inspected before assembly after use. Using on-site assembly of equipment, on-site inspection and machine performance. 3) should hold production licenses issued by the relevant departments. 4) the overall structure, water line, gas line and electrical equipment should be reasonable layout line, should leave space for easy installation and maintenance operations. 5) purchased parts and materials and other equipment for use should be selected in line with national standards (the industry standard) products. Structural requirements 6) pump units:... A regulator pump should pump equipment, their ability to work and the work should be the same b pump pump regulator should be set for each individual water pump suction pipe c manner that self-leveling 7 ) pressure tank storage volume Fire Hydrant System is not less than 300L; automatic sprinkler system pressure tank storage capacity of not less than 150L; hydrant and sprinkler systems combined pressure tank storage capacity of not less than 450L; 8) of the device is equipped with two regulation pumps (one with a prepared).
