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

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
