[Asia Pump Network News] fire pump, as the name implies, the fire pump. Fire pump with a fully sealed, leak-proof, corrosion-resistant, etc., are widely used in environmental protection, water treatment, fire and other departments for pumping all kinds of liquids, is to create a leak-free, pollution-free civilized workshops, civilized factories ideal pump. Practical fire pump equipment procurement Raiders Inventory: Selection and installation should be cautious Many engineering companies in the purchase of fire pump equipment, fire pump equipment management do not understand. So how can we purchase a cost-effective fire pump equipment? Next, Asia Fluid Network Xiaobian share in this fire pump selection Raiders, and installation, as follows: First, the selection of fire pump equipment Matters needing attention 1 The flow and lift of the fire pump shall be calculated and determined according to the requirements on fire fighting water quantity and pressure of the project serviced. 2. The selected fire pump should be the national fire safety product quality supervision and inspection agencies type test, and in line with "fire pump" GB6245-2006 requirements. 3. According to the characteristics of the project, the power supply and fire pump room location, area and fire water supply system, the specific circumstances of choice, to determine the type of fire pump. 4. Temporary high-pressure or high-pressure fire water supply system fire pump should be used one by one or a multi-purpose backup mode of operation. The spare pump should be the same as the working pump, and the working capacity should not be less than one of the largest fire pumps in service. When the multi-use a prepared, should consider the pump flow superposition, the impact on the pump outlet pressure. 5. According to "Code for fire protection of building design" (GB50016--2006): fire pump should be equipped with spare pump, its working capacity should not be less than the maximum of a fire pump. When the factory, warehouse, storage yard and tank outdoor fire water is less than or equal to 25L / s or indoor fire water for construction is less than or equal to l0L / s, do not set the backup pump. Fire pumps should be guaranteed within 30 seconds after the start of the fire. Fire pumps and power machinery should be connected directly. 6. Fire pump motor shaft power should meet the pump operating conditions (pump curve) work requirements. The pump performance curve without hump, fire pump stop pump pressure should not exceed 140% of the system design rated pressure, when the pump flow rate of 150% of rated flow, then the pump pressure should not be less than 65% of rated pressure . Second, the common installation of fire pump equipment 1. Rigid coupling installation: Due to the vibration of the pump is small, the fire pump can be installed directly on the base plate precast concrete Tsuen (see installation diagram), which can meet the requirements , Suitable for most occasions. Anti-vibration installation: In general hotels, office buildings and special requirements of the place, you can use vibration-proof installation, which is added below the bottom of the pump floor plate, and then placed on four anti-vibration device, and then bolted on the cement foundation On (see installation diagram). 2. Prepare anchor bolts (hexagonal bolts, expansion bolts), flat washers, spring washers, nuts, etc. according to the installation dimensions of the selected fire pump model and installation method, and prepare the cement foundation according to the installation method and embed Good anchor bolts. After the foundation is dry, clean the debris and dust on the foundation installation surface and check the horizontal surface of the foundation installation surface with a flat ruler. 3. Remove the oil stains and dirt on the bottom of the fire pump. Hoist the pump to the basic installation position according to the installation drawing. Check the direction of the inlet and outlet. Place washers, spring washers on the bolts and tighten the nuts. 4. Coupling pump import and export pipeline: In order to maintain the convenience and safety, require the installation of a control valve on the import and export pipelines, the best in the vicinity of the pump outlet to install a pressure gauge in order to regulate and ensure that the fire pump at rated flow And within the scope of head operation, to ensure the normal operation of the pump and increase the life of the pump. 5. Installation of pipelines, the weight of the pipe should not be added to the pump, so as not to grab the trap shape. When we purchase fire pump equipment, in addition to the above classification management requirements, if the fire pump equipment manufacturers or fire pump equipment vendors can not provide the appropriate procedures and product quality inspection reports, it may be counterfeit fire pump equipment products . If the user is indeed difficult to identify, you can consult the local fire control products industry supervision and management or product inspection agencies check.
