High Pressure Fire Fighting Water Electric Pump

High-Pressure Fire Fighting Water Electric PumpXBD-(I) vertical single-suction multi-stage fire pump set is a new generation of XBD pipeline medium and low-pressure fire pump set developed by our company based on the original vertical multistage pipeline pump according to the standard requirements of fire pumps.It is used to transport clean water without solid particles and liquids with physical and chemical properties similar to water.It is suitable for fire-fighting water supply on various occasions such as residences, hotels, office buildings, commercial buildings, factories, hospitals, etc.  Characteristics:1. Compact structure, small, nice, vertical installation, less area for installation needed, gravity on feet, stable running, and long life.2. Stable running, little noise, highly concentric components.3. Advanced hydraulic model, high efficiency, and performance.4. The superior mechanical shaft seal, highly endurable against friction, no leak, long life.5. The pump inlet and outlet are on the same horizontal line, same sizes, easy to install, and uninstall.6. Easy to maintain, pipes uninstall is not needed, you only need to take off pump cap nuts, then take out motor and transmission elements, before maintaining.Application range:Mainly applied in firefight system pipes pressure boosted water supply, industrial and municipal water supply, and drain, high-building architecture pressure boosted water supply, remote water supply, heating, bathrooms, boiler cold & hot water circulation, pressure boosted air-conditioning system water supply and peripheral facilities.Technical parameters:flow: 2 - 162 L/S;pressure: 0.10-1.25Mpa;power: 1.1-132KW;rotation speed: 2900r/min;diameter: φ25-φ150;temperature range:≤80ºC.Model Number Flow Q (L/s)Head (m)Speed n (r/min)Power P (kW)Efficiency η (%)Diameter (mm)XBD3.6/0.56-(I)25X323629001.13025XBD4.8/0.56-(I)25X424829001.13025XBD6/0.56-(I)25X526029001.53025XBD7.2/0.56-(I)25X627229001.53025XBD8.4/0.56-(I)25X728729002.23025XBD9.6/0.56-(I)25X829629002.23025XBD10.8/0.56-(I)25X9210829002.23025XBD12/0.56-(I)25X102120290033025XBD13.2/0.56-(I)25X112132290033025XBD14.4/0.56-(I)25X122144290033025XBD3.3/1.11-(I)25X343329001.14025XBD4.4/1.11-(I)25X444429001.54025XBD6.6/1.11-(I)25X646629002.24025XBD7.7/1.11-(I)25X747729002.24025XBD8.8/1.11-(I)25X8488290034025XBD9.9/1.11-(I)25X9499290034025XBD11/1.11-(I)25X104110290044025XBD12.1/1.11-(I)25X114121290044025XBD13.2/1.11-(I)25X124132290044025XBD14.3/1.11-(I)25X134143290044025Start, running and stop Start1. First of all, pour water into pipes, to make the pump and inlet pipe filled with water. The pipes shall be sealed, no air leaked. (no-water inside start is forbidden) 2. Close globe valve and cock on outlet pipe, to reduce start currency.3. Rotate the rotor by hand, lubricate the bearing and check the pump impeller, seal the ring, if it cannot rotate, you shall not start.4. Try to start, motor rotation direction shall be as same as the arrow direction on the pump. 5. When the rotor works normally, open gradually the outlet globe valve, adjust for the work conditions required.Running1. Observe the reading in meters, keep it running around the flow and head shown on the nameplate.2. Regularly check, motor currency value shall not exceed rated currency value.3. Pump bearing temperature shall not exceed 75ºC, and shall not be 35ºC higher than ambient environment.4. To start, loosen the stuff cap. Adjust later when started.5. In case of fragile component abrasion, replace in time.6. When any abnormal happens, immediately stop and check.Stop1. Close the globe valve on the outlet pipe, close the vacuum gauge cock.2. Stop the motor, and close the pressure cock.3. In Winter, drain the liquid in the pump completely to avoid frozen cracks.4. When you will not use it for a long time, uninstall the pump, clean, and lubricate.Troubleshooting   FaultCauseSolutionThe pump cannot suck water, pressure gauge & vacuum gauge vibrating 1. Insufficient water pouring 2. Leak between pipe and meter 3. Suction is too high 1, check a leak in the bottom valve. 2, Tighten the leaked part 3, reduce suction The pump cannot suck, high vacuum is shown in the vacuum gauge1, bottom valve closed or jammed 2, Too great water suction resistance 3, filter jammed 1, check bottom valve2, replace water suction pipe3, clear off the filterPressure gauge works, no water outcome1. Great outlet water pipe resistance2. Wrong rotation direction 3. Outlet pipe valve closed4. impeller jammed 1. check or shorten water pipe 2, check the motor, adjust 3, open the valve and clear off the impellerCannot reach designed flow1. air sucked 2. Water level drops, submerged depth is not enough 3. impeller jammed 4. rotor torn and worn 1, check leak part and clear off 2, prolong water inlet pipe, increase the submerged depth3, uninstall and clear off 4, replace seal ring Great pump power consumption1. Stuff tightened, overheated 2. Great flow 3. Collision between rotor and case 4. Pump shaft bea
