In recent years, multi-stage fire pump more and more favored by the majority of users, which is mainly used for fire-fighting system pipeline pressurized water. Can also be applied to industrial city water supply and drainage, high-rise building pressurized water supply, long-distance water supply, heating, bathroom, boilers, heating and cooling water circulation pressurized air conditioning and cooling system water supply and equipment and other occasions. Really because of its wide range of uses, so in the pump market holds an important place. Today Xiaobian here for you to interpret the multi-level fire pump products, to see why it is highly favored? Analyze multi-stage fire pump structure Multi-level fire pump 1), pump structure should ensure easy on-site maintenance and replacement parts. Fasteners and self-locking device should not be loose due to vibration and other reasons. 2) The pump should be cast on the arrow indicating the direction of rotation. 3), should be pressure gauges, vacuum gauges (submersible pumps, deep well pumps except), table accuracy should not be less than 2.5. 4), the pump should set the drain cock. 5), the nominal pressure of the pump outlet flange should be able to meet the requirements of the maximum working pressure, the nominal pressure of the pump inlet flange should not be less than 1.0MPa. Flange connection size should be consistent with the provisions of GB / T 9112-2000 and GB / T 9124-2000. 6), the pump inlet should be able to withstand the positive pressure of 0.4MPa. Advantages of multi-stage fire pump inventory using a special hydraulic design and structural design, so that the flow pressure sub-file is more suitable than ordinary centrifugal water pump construction fire water supply system selection, flow-pressure characteristic curve is flat without hump. High reliability due to wear-resistant, corrosion-resistant, anti-mesh materials for all parts that generate friction due to rotation. Multi-stage pump can be equipped with double water outlet, high carrying capacity of pump body, strong anti-overload capability, .
