In recent years, with the adjustment of agricultural structure, farmers make full use of low slope and wasteland resources, large-scale development of efficient agriculture, but these are often difficult to gravity irrigation. Need to buy water pump irrigation. So, how to buy the right agricultural pump? The following tips for farmers friends.
First of all, according to local conditions to buy pumps. Commonly used agricultural water pumps have three types, namely, centrifugal pumps, axial flow pumps and mixed-flow pump. Axial flow pump is larger, but the lift is not too high, for use in plain areas; mixed flow pump and the lift of the pump head between the centrifugal pump And axial flow pump, suitable for use in plains and hilly areas. The user according to the local conditions, water and lift the height of the purchase.
Second, to appropriate over-election pump. Determine the pump type, to consider its economic performance, with particular attention to the pump head and flow and supporting the choice of power. It must be noted that there is a difference between the head (total head) indicated on the pump plate and the water head (actual head) when it is used. This is due to the loss of resistance in the vicinity of the water pipe and pipeline. Therefore, the actual head is generally lower than the total head 10% - 20%, a corresponding reduction in water. Therefore, the actual use, according to the label only note the head and flow of 80% to 90% of the estimated pump supporting the choice of power, according to the label on the power selection, in order to make the pump start quickly and safe use of power Power can also be slightly larger than the power required for pumps, generally about 10% higher than appropriate; if you have power, buy water pump, you can press the power of the machine to buy matching pump.
Finally, to strictly purchase the pump. The purchase of pumps, but also to test the "three card", that is, promotion of agricultural machinery permits, production licenses and product testing certificate, only three cards can be purchased in order to avoid the complete elimination of products and inferior products.
