How to choose and buy agricultural water pumps?
In recent years, with the adjustment of agricultural structure, farmers have made full use of low mountain
gentle slope and wasteland resources to develop efficient agriculture in a large area, but these plots are often
difficult to self-flow irrigation. Need to purchase water pump for irrigation.
So, how to choose and buy the appropriate agricultural water pump?
The following tips are for farmers' reference.
First of all, choose and buy water pumps according to local conditions.
-The centrifugal pump has a high lift, but a small water output, which is suitable for mountainous areas and well irrigation areas.
-The axial flow pump has a large water output, but its head is not too high, which is suitable for use in plain areas.
-The output and head of the mixed-flow pump are between the centrifugal pump and the axial flow pump, which is
suitable for use in plain and hilly areas. Users should select and purchase according to local land conditions, water sources and water lifting height.
Secondly, the water pump should be selected appropriately.
After determining the type of water pump, its economic performance should be considered.
Especially the head and flow of the water pump and the selection of its supporting power.
It must be noted that the head (total head) indicated on the water pump nameplate is different from the
outlet head (actual head) when it is used, because there will be certain resistance loss when the water flows
through the water delivery pipe and near the pipeline. Therefore, the actual head is generally 10% - 20% lower than t
he total head, and the water output is also reduced accordingly.
Therefore, in actual use, it can only be estimated according to 80%~90% of the head and flow indicated on the nameplate.
The power of the water pump can be selected according to the power indicated on the nameplate. In order to make the water pump
start quickly and use safely, the power of the power machine can also be slightly higher than the power required by the water pump,
generally about 10% higher; If the power is available, when purchasing the water pump, the matching water pump can be purchased
according to the power of the power machine.
Finally, strict procedures should be followed to purchase water pumps.
The "three certificates", namely agricultural machinery promotion license, production license and product inspection certificate,
should also be checked when selecting and purchasing water pumps. Only when the three certificates are complete can the purchase of obsolete
products and inferior products be avoided.
