XBD-DL fixed vertical multi-stage fire pump

New Product Overview
) The new DD-type vertical single-suction multi-stage segmented fire pump set is used to transport clean water without solid particles and liquids with physical and chemical properties similar to water. It is mainly used for pressurized water supply in fire protection system pipelines. It is also suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise buildings, water transport over long distances, heating, bathrooms, boiler hot and cold water circulation pressurization, air conditioning and refrigeration system water supply and equipment matching, etc.
) The performance and technical conditions of the BD series fire pumps produced by the new company comply with the requirements of the newly promulgated national standard B "Performance Requirements and Test Methods for Fire Pumps". All products of Hulong Company are designed and optimized by computers. , the company has strong technical force, rich production experience and complete testing methods to ensure stable and reliable product quality.
) Characteristics of the new multi-stage fire pump
) The new pump has a compact mechanism, small size and beautiful appearance. Its vertical mechanism determines the small installation area, and its center of gravity coincides with the center of the pump feet, thus enhancing the strength of the pump. operational stability and service life.
) New, the pump suction inlet and discharge outlet are both horizontal, simplifying the pipeline connection.
) New, according to needs, the suction port and the discharge port can be installed in the same direction or in different directions d, d, d to meet different connection occasions.
) New, the pump pressure can be increased or decreased according to the needs of the pump stage and the outer diameter of the impeller can be cut to meet the requirements without changing the installation area, which is not available in other pumps.
) The new pump rotor has a small winding, smooth operation, small vibration, low noise and long service life.
) New DD type vertical single-suction multi-stage segmented fire pump unit installation instructions
) The weight of the pipeline should not be borne on the pump during new installation, otherwise the pump will be easily damaged
) New The pump and motor are an integral structure and have been calibrated by the manufacturer before leaving the factory, so there is no need to adjust during installation, so the installation is very convenient
) The anchor bolts must be tightened during new installation, and the pump should be inspected at regular intervals to prevent it from being damaged. Loose to avoid severe vibration during startup, which will affect the performance of the pump
) Before installing a new water pump, you should carefully check whether there are any hard substances (such as stones, iron sand, etc.) in the pump flow channel that will affect the operation of the water pump to prevent the water pump from running out of time. Damage to flow-passing components
) New For the convenience of maintenance and safe use, a regulating valve is installed on the inlet and outlet pipelines of the pump and a pressure gauge is installed near the inlet and outlet of the pump. For high-lift pumps, in order to prevent water hammer, a check valve should be installed in front of the outlet gate valve to cope with power loss accidents such as sudden power outages, thereby ensuring that the water pump operates under optimal working conditions and extending the service life of the water pump
) When a new pump is used in situations with a suction lift, it should be equipped with a bottom valve, and the inlet pipeline should not have too many bends, and there should be no water or air leakage to avoid affecting the suction performance of the water pump
) In order to prevent impurities from entering the pump and clogging the flow path and affecting performance, a filter should be installed in front of the pump inlet
) Rotate the rotor component of the water pump before tightening the pipeline. There should be no friction or sticking, otherwise The pump should be disassembled to examine the cause.
