The daily maintenance of fountain project

Time：2013/12/3 22:34:00 Viewed ：477

1. The fountain of the water quality requirements
Water supply water quality should be consistent with the current "water health standard" regulation of sensory properties index requirements:
(1) chroma does not exceed 15 degrees, and shall not render other different color, turbidity is not more than 10 degrees.Must not contain any visible to the naked eye.
(2) the physical and chemical indicators
The water content of impurities is not greater than 0.1% impurities particle size is not more than 0.2 mm
Chloride ion content is less than 400 mm/L value in the range of 6.5 ~ 8.5
2. Filling water fountain project requirements
A fountain of water should be recycled.When required by the nozzle have, circulating water should be filtered.Supplement water circulation system should according to the evaporation, the wind blows, leakage loss to determine, sewage, such as, general appropriate USES circular flow 5 ~ 10%.
3. The fountain pool line
Fountain should be set up, return pipe, overflow pipes, drain pipe and drain pipes empty facilities, return pipe should be set up on the screen.Fountain appropriate circular pipes to decorate, distribution pipe head loss generally appropriate USES 5 ~ 10 mm/m.Fountain of the water distribution pipeline joints should be tight smooth, variable diameter pipe should use reducer, pipe bend should be smooth bend of large turning radius.Nozzle should be not less than 20 times before the nozzle mouth diameter of straight pipe sections or rectifier device.
4. The shower nozzle maintenance
Nozzle should be regular cleaning maintenance regularly, the nozzle should be paid attention to when installation and connection of tightness, the nozzle should be in the line of silk tie up a layer of teflon tape, lest appear slack phenomenon, influence water effect, should complete nozzle of security measures at the same time.
5. The maintenance of underwater lights
Underwater lights is more easily damaged parts in the fountain in the component, in order to decrease the damage rate of the lights should be paid attention to the following:
(1) in the piping welding lamp, lamp piece of welding must be tight, prevent light chipped in use process.
(2) assembly lamps and lanterns, to connect the lights and lighting fixtures tighten, not loosen.
(3) after the assembly, lamps and lanterns should be immersed in 5% of the salt water for 72 hours, the measurement value of qualified rear can use.
(4) the underwater joints to butt up correctly, and heat shrinkable tubes and hot-melt adhesive waterproof.
6. Fountain pump maintenance
(1) the pump should be installed firmly.Runtime small power pump inlet must be 300 mm under the dynamic water level, and high power pump inlet must be under dynamic water level 1 m.
(2) the water pump leads to cable link respectively with three core cable with tin welding, welding rosin residues such as oil or dry, then use adhesive tape and a half fold bundle tight, wrap adhesive tape thickness not less than 2 mm, immersed in water for 24 hours measuring insulation resistance is not less than 100 ohms.
(3) pump thrown check each running 2500 hours, small or continuous run of 1500 hours inspection once half a year.Check whether there is any damage on the unit, fasteners loose, cable with and without damage, the other filter water, turn the pump shaft from the feed section should be flexible, can not have stuck phenomenon.
(4) faults and ruled out
Failure phenomena, causes and elimination method, no water, indirect or less water
1), the motor start
2), and blockage of the piping
3), the pipeline rupture
4), filter chocked up with water
5), water intake above the water
6), electric pump reversal
7), sealing ring, damage of impeller
measures
1), eliminate circuit malfunction
2), remove blockages
3), or repair welding in pipe
4), unclog
5), switch power phase sequence
6), change a new one
The motor can't start with buzz
1), one of the circuit
2), the bearing axis
3), impeller with foreign body
4), low voltage
measures
1), repair line
2), repair or replace the bearing
3), the removal of foreign bodies
4), adjust the voltage
Motor winding insulation resistance to earth on the low side, winding and cable connector or cable is damaged, replace winding repair joint or cable.
