Drainage pump fault troubleshooting

No water after start-up: there is air or water in the pump to accumulate gas, or the bottom valve is not strictly filled with water, the vacuum pump is filled with a serious gas leak, and the gate or shutter is closed. Exclusion: remove debris, replace the damaged rubber pad, change the direction of the valve; press or replace the new packing, close the gate valve or pat the door; increase the filling amount until the deflation plug does not bubble up; replace Cracked pipe; lower head, the pump nozzle into the submerged 0.5 meters. Start pump does not turn: packing is too tight or between the impeller and the pump is clogged with debris, or the pump shaft, bearings, leakage ring rust live, or serious bending of the pump shaft. Exclusion: Loose packing, clear diversion trough; open the pump to remove debris, rust; remove the pump shaft to correct or replace the new pump shaft. Pump heat bearing damage: Rolling bearing or bracket cover gap is too small; shaft bending or two axes are not the same; tape is too tight; lack of oil or poor oil quality; impeller balance hole plug, impeller out of balance, increasing the direction Thrust on one side. Exclude: replace the bearing; remove the back cover, install the gasket between the bracket and the bearing seat; adjust the pump shaft or adjust the concentricity of the two shafts; adjust the tightness of the tape properly; add clean butter and butter to the bearing 60% of the gap; remove the blockage in the balance hole. Insufficient flow after starting: insufficient speed or belt slippage, resulting in low speed; axial pump blade mounting angle is too small; insufficient lift; suction stroke is too high; bottom valve, pipe and impeller partial blockage or impeller defect; serious. Exclude: restore the rated speed, remove the belt grease, adjust the belt tightness; adjust the blade angle, lower the pump installation location; sealed pump leak, compaction packing; remove clogs, replace the impeller; Department.

Suggestions:

1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.

2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.

3. Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.

4. While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp
