Product Overview 
 XBD-L vertical single-stage single-suction fire pump for conveying contain solid particles and water and physical and chemical properties similar to water or liquids. The single-stage fire pump is mainly used for the fire system, pressurized water can also be used in factories, mines and water supply and drainage. Transmission fluid flow range of 5 ~ 80L / S, the pressure range of 0.2 ~ 2.25MPa, supporting a power range of 1.5 ~ 200KW caliber range φ50 ~ φ250mm. 
 For the fire protection system piping pressurized water. Also be applied to the industrial city water supply and drainage, high-rise building pressurized water supply, long-distance water, heating, bathroom, boiler warm and cold pressurized water cycle air-conditioning refrigeration systems and bottled water and equipment for occasions, instead of the original IS type centrifugal pump. 
 Structure Description 
 XBD-L vertical single-stage single-suction fire pump, composed of two parts of the motor and pump, pump and motor coaxial, fire pump structure includes the pump body, impeller, pump cover, mechanical seals and other components. Pump imports and exports in the same horizontal axis, and the same caliber specification, loading and unloading is extremely convenient, small footprint. The pump has a mounting base, easy to install, and increase the stability of the pump running. Seal pump mechanical seal, with a reliable seal, no leakage characteristics. The axial force of the pump impeller balance ring to balance. Pump inlet and outlet flanges to 1.6MPa, the pipeline supporting convenience. 
 XBD-L Multistage Fire Pump, composed by two parts of the motor pump and motor for the Y-shaped three-phase asynchronous motor, pump and motor shaft coupling, the overall rigid connection, when used without correction. The pump is driven by the stator and rotor parts. The pump stator in part by the water segment, the middle of the guide vanes, the water segment, stuffing body parts. In order to prevent the stator wear, the stator is equipped with a sealing ring, balanced sets, available spare parts to replace worn. The rotor part of the axis, in the round. The balance drum. Rotor bottom of the water lubricated bearing, the upper angular contact ball bearings, the axial force of the pump were provided by the balance drum to bear the remaining small portion of residual axis angular contact ball bearings to withstand the force. The combination of surface water, middle and outlet sections of paper pad through the tension to reach the seal, the user can be chosen. 

 Single-stage fire pump installation requirements 
 A pre-installation check the water pump in good condition. 
 Two fire pumps should be installed as close as possible to its source. 
 Fire pump and the base is installed in two ways, one is directly installed in the cement on the basis of the rigid connection, another is a flexible connection using the JGD type shock absorber installation. 
 (4) direct installation can pump placed on the basis of the booster 30 to 40 mm (ready to fill grout), and then corrected, and put the bolt, filling cement mortar, by 3 to 5 days after the cement dried, re- correction, until the cement is completely dried up, tighten the anchor bolt nuts. 
 Install piping, into the outlet road should have their own support, should not put too much weight of pipe flange of the pump. 
 The pump is used to have Suction occasions, the inlet side should be equipped with a bottom valve, and inlet and outlet pipeline should not have too many corners, at the same time not have a leak, the presence of air leaks. 
 Way inlet tube is best equipped with a filter to prevent impurities into the impeller internal. The effective area of ??the filter into the water distribution area of ??3 to 4 times in order to ensure the free flow of liquid. 
 8, each equipped with a regulating valve near the pump outlet to install a pressure gauge, pump inlet and outlet pipes on the road in order to maintain and easy to use security to ensure that run within the rated range, to ensure the normal operation and service life of the pump. 
 Nine. For imports expanding connection, please use the eccentric reducing pipe joints. 
 Unit start-up, operation and parking of 
 The main features 

 1, the structure of the fire pump is compact, small size, beautiful appearance, its horizontal structure, decided to install a small footprint, its center of gravity coincide, thereby enhancing the stability and service life of the operation of the pump at a pump foot center. 
 2, the fire pump inlet and outlet are horizontally, simplifying the piping connections. 
 3, multi-stage fire pump according to need, inhaling the mouth and spit exports can be installed into the same direction or 90 ° 180 ° 270 ° a few different directions to meet the different connections occasions. 
 4, the fire pump pressure according to the need to increase or decrease in series pump and cutting impeller diameter to be met without changing the installation covers an area of ??other pumps do not have. 
 5, the pump rotor has a smaller around, smooth running, small vibration, low noise, long service life. 
 XBD-L vertical single-stage single-suction fire pump products use 
 First, start 
 Fire pump for suction lift situations, ie, imports for the negative pressure in the first pipeline irrigation or with a vacuum pump diversion, so that the water is full of the entire pump and the import pipeline, pay attention to the import pipeline must be sealed and shall not be the presence of air leaks. (Before starting is prohibited without a water start, must be advanced water after starting) 
 Close the gate valve on the outlet pipe and the pressure gauge cock, in order to reduce the starting current. 
 Hand to rotate the rotor a few times, bearing lubrication and check the pump impeller and sealing ring operation with or without grazing, such as genetically fixed, should not start until you find the cause of the malfunction. 
 4 test starter motor turn should pump on the arrows pointing to open the account cocks. 
 When the rotor to achieve normal operation, the pressure gauge shows the pressure, and gradually open the exit valve, adjusted to the required conditions. 
 Second, running 
 A fire pump in operation, must pay attention to observe the meter reading, as much as possible so that the pump nameplate near the flow head, to prevent the running of large flow. 
 (2) regularly check the motor current value should not exceed the rated current. 
 (3) Fire Pump bearing temperature shall not exceed 75 ℃, and shall not exceed the outside temperature is 35 ℃. 
 (4) the pump should start running loosen packing gland expandable graphite packing fully expanded and then adjusted to the appropriate level. 
 The 5. Wearing parts wear should be promptly replaced. 
 6. The abnormality is found, immediately shut down the cause of the check. 

 Third, the downtime 

 Close the outlet line of the valve, close the vacuum gauge cocks. 
 (2) stop the motor, and then close the pressure gauge cock. 
 (3) If the cold winter season, should pump liquid exhausted, so as to avoid the cracking. 
 Long-term suspension, should pump disassembly, cleaning oil for safekeeping.
