The purchase of agricultural pumps:
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 choose the right agricultural pump has become a farmer friends need to solve a problem? The following tips can be a reference for farmers friends.
First, 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 be 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.
Third, we must 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.
The use of pumps maintenance:
Farmers will buy back the pump, how to properly use the pump to maximize the effectiveness of it? If the use of unreasonable will shorten the life of the pump, so the correct use of methods to extend the life of the pump to reduce the economic loss of the important factors.
First, for the submersible pump, before starting to do some necessary checks: the shaft rotation is normal, with or without stuck phenomenon; impeller position is normal; cable and cable plugs without cracks, abrasions and broken phenomenon . Operation should pay attention to observe the voltage changes, the general control of the rated voltage within ± 5% range. In addition, the location of the pump in the water is very important, should be selected in the water is abundant, no silt, good water quality, vertical suspension in the water, do not allow horizontal, so as to avoid mud or suspended solids blocked pump imports, and Resulting in a sharp drop in water or even pumping not to Sheung Shui.
Second, for the self-priming pump, should be placed as far as possible in a well ventilated place to run, in order to facilitate rapid cooling, reduce motor temperature. Otherwise, a long time running, easy to burn the motor. Such as a farmer in the use of self-priming pump, because there is no cover removed in the motor plastic film, resulting in motor overheating, burned the coil. In addition, before starting, be sure to check the pump body of water, otherwise, not only affect the self-priming performance, and easy to burn the shaft seal components. Under normal circumstances, the pump should start 3-5 minutes after the water, or should immediately stop inspection.
Third, when the pump once the failure, should not disassemble themselves. Because of their demolition, one does not know where the fault caused by the blind disassembly of a pass; the second is no special tools and often damage the original intact parts. The best way is to have experience, the size of the maintenance point of repair, and the timely replacement of "overage" parts and some wearing parts. Under normal circumstances, the pump should be repaired once every six months, to eliminate the "disease" work
Fourth, in the non-use period, the pump should be promptly lifted from the water, and emptying pump water, especially in the cold winter. And then placed in a dry place, conditional users can also be painted in the key parts of the butter, lubricating oil in the bearing to prevent corrosion of parts. In addition, the pump's non-use period, not the longer the better. If not used for a long time, not only easy to rust parts, but also reduce the pump life
