Installation knowledge of large drainage pump users:
1. Check carefully before installing large drainage pumps
Before installing a large-scale drainage pump, first check whether the pump shaft rotates flexibly. If it is found that the pump shaft rotates inflexibly, there is an impact sound, and the pump shaft shakes radially, the fault should be eliminated before installation. Secondly, check whether the water inlet hose is damaged, if there is crack, it should be repaired in time.
2. Proper power distribution for large drainage pumps
The power cord should be selected according to regulations, the cable should be overhead, and the power cord should not be too long. If the distance between the power supply and the large drainage pump is far, the cross-sectional area of the conductor of the connecting cable should be appropriately increased, and the number of connectors should be as small as possible to reduce the line pressure drop.
3. Large-scale drainage pumps must have two-level leakage protection measures
To ensure safety, a metal rod with a length of 1m or more can be buried in the wet ground near the power supply or the pump as the grounding body of the large drainage pump. Also install an earth leakage protector.
4.Check the rotation direction of the motor before the large drainage pump enters the water
Because there are many types of large-scale drainage pumps that can produce water during forward and reverse rotation, but the amount of water is small and the current is large during reverse rotation. The longer the reverse rotation time will damage the motor windings. Therefore, before entering the water of a large drainage pump manufacturer , first connect the power supply to check whether the rotation direction is correct.
5.The installation location of large drainage pumps should be correct
The submersion depth of oil-filled large-scale drainage pump should be 0.35 ~ 3m, and the depth of zui should not exceed 10m; the submergence depth of dry, semi-dry, water-filled large-scale drainage pump is 1m. Excessive depth will affect the mechanical sealing effect.
6. Testing of insulation resistance after the installation of large-scale agricultural drainage pumps
After the installation of the large-scale drainage pump, use a 500V megohmmeter to measure the insulation resistance between the windings and between the windings and the ground, which should not be less than 0.5MΩ.
7. Setting safety warning signs To prevent accidents, obvious warning signs should be set up near large drainage pumps. To ensure safety, it is strictly forbidden for people and livestock to come into contact with water near the exit of a large drainage pump.
