How to buy agricultural stainless steel submersible pump

In recent years, with the adjustment of agricultural structure, farmers make full use of low slope and wasteland capital, large area to carry out efficient agriculture, but these blocks are usually difficult to gravity irrigation. Need to purchase stainless steel water pump irrigation. So, how to choose the appropriate agricultural stainless steel pump? The following tips for farmers to see friends.

First, to be tailored to purchase stainless steel submersible pump. Commonly used agricultural stainless steel pumps have three types, namely, centrifugal pump, axial flow pump and mixed flow pump. Axial flow pump is larger, but the lift is not too high, for the use of the plain area; mixed flow pump and the head of the water flow between the centrifugal pump is suitable for water supply, And axial flow pump, suitable for plain and hilly areas. The user according to the local conditions, water and lift the height of the purchase.

Second, to over-select the appropriate stainless steel water pump. Determine the type of stainless steel water pump, to consider its economic functions, in particular, pay attention to the stainless steel pump head and flow and the matching power of selection. It must be noted that stainless steel pump marked on the head (total head) and the use of the water head (practice head) is different, because the water flow through the pipeline and the pipeline will have a certain resistance to loss. Therefore, the practical lift is usually lower than the total head 10% -20%, a corresponding reduction in water. Therefore, the practice of use, according to the label only note the head and flow of 80% to 90% of the budget, matching the selection of stainless steel pump power, according to the specified power on the plate selection, in order to make stainless steel pump agile and safe use, The power of the power machine can also be slightly larger than the power required for pumps, usually about 10% higher than the appropriate; if there is power, buy stainless steel pump, you can press the power to buy matching power supply with stainless steel pumps.

In the end, to purchase stainless steel pumps. When purchasing stainless steel pumps, we must also examine the "three certificates", that is, the implementation of agricultural machinery license, production license and product inspection certificate, only three cards can be completed in order to avoid purchase screening products and defective products.
