Agricultural water pump installation technical requirements are very strict. First of all, water pump base should be str ong, and try to
shorten the length of the suction pipe. Secondly, the water pipe should be sealed and reliable. The bottom valve and hose Insurance rope
fastened. Water channels, the bottom valve should be more than 0.5 meters above the bottom, and screening to prevent debris into the
pump. The third is when the pump belt drive, the tight side of the belt should be the next in order to improve transmission efficiency.
The pump impeller steering should be consistent with the direction of the arrow.
Check the pump should pay attention to three points:
(1) The shaft should be flexible rotation, percussion; shaft radial no significant shaking, the need to add a little lubricant.
(2) Check the water hose without damage, if cracking stick timely repair. Check the fastening bolts loose, you want to tighten loose
bolts.
(3) submersible pump motor windings, cable insulation shall meet the requirements in order to use.
Troubleshooting methods:
(1) does not absorb water or no water, multi-valve stuck in the end, the treatment part of the blockage; absorbent height is too high or
suction pipe leak; impeller blockage caused shall take appropriate solution.
(2) pipeline leaks or leak, installation bolt is loose. If the leakage is not severe, the coating slurry in the place of leakage or
leak, and tighten the nut with a spanner; if the leakage is serious, will have to reinstall.
(3) pump severe vibration, may be combined with the bad in the electric rotor imbalance, or coupling, bearing wear, bending; may be
caused by the rotating parts relaxation, rupture and pipe bracket is not strong cause. Should be depending on the circumstances,
adjustments, reinforcement, straightening or replacement.
