Pump use and maintenance:
After the pump farmers buy, how to properly use the pump in order to maximize the effectiveness of it? If using unreasonable will shorten the life of the pump, so correctly use is an important factor to extend pump life and reduce economic losses.
For submersible pumps, should be done before starting the necessary checks: whether the normal rotation of the shaft, with or without stuck phenomenon; impeller position is normal; cables and cable plugs for cracks, scratches and breakage phenomena. Operation to observe the changes in voltage, generally controlled within ¡À 5% of rated voltage. In addition, the location of the pump in the water is very important, as far as possible the election in plenty of water, no mud, water quality good place, suspended vertically in the water, not allowed to be placed horizontally, so as not to fall into the mud or suspended solids clogged pump inlet, and leading to a sharp drop in water no water pumping even come.
For the pump, should be placed as far as possible in the run-ventilated place, in order to facilitate rapid cooling, reduce motor temperature. Otherwise, the long-running, easy burning motor. If a farmer in the use of a pump, because there is no remove the plastic film covering the motor, resulting in motor overheating, burned out coil. Also, before you start, be sure to check storage capacity of the pump body, otherwise, not only affects the self-absorption performance, and easy to burn seal components. Under normal circumstances, the pump starts after 3-5 minutes the water should be, or should be shut down immediately checked.
When the pump in the event of a fault, should not it-yourself removal. Because their removal, one I do not know where the fault caused by blindly indiscriminate demolition of a pass; Second, no special tools are often damaged the original parts intact. The best way is to have the experience, the maintenance of a large scale maintenance and timely replacement of "overage" of certain parts and wearing parts. Under normal circumstances, the pump should be maintenance once every six months, to eliminate with "sick" work.
In the non-use period, should be promptly lifted off the water pump and emptying pump water, especially during the cold winter months. Then place a dry place, users can also conditional butter in key parts of the pump, plus the lubricant in the bearing to prevent rusting parts. In addition, the non-use of the pump, not the longer the better. If you do not use for a long time, not only easily corroded parts, but also reduce the life of the pump.
Pump purchase:
To local conditions to buy pumps. There are three common types of agricultural pumps, namely, centrifugal, axial and mixed flow pumps. High centrifugal pump head, but the water is not suitable for mountainous and well irrigation area; axial pump a greater amount of water, but the head is not too high for the use of plain areas; Francis pump out water and lift between centrifugal and between the pump, apply to the plains and hilly regions. Users should attach to choose according to local conditions, water and carry water.
To choose the appropriate pump exceeded. Determine the pump type, to consider their economic performance, with particular attention to the head and flow and supporting dynamic selection of pumps. It must be noted on the label of the lift pump (total head) and water lift (the actual head) to use when there is a difference, it is there will be some resistance losses due to water flowing through pipes and piping the output when nearby. Therefore, the actual head than the general 10% -20% of the total head low, the water is also reduced. Therefore, the actual use, only by signs that 80% to 90% Note head and flow estimates, pumps motive power of choice, according to the signs indicate the power options, in order to make the pump start fast and safe to use, power machine power can also be slightly larger than the pump power required, generally about 10 percent higher than is appropriate; If you have power, when purchasing pumps, you can press the power machine's power to buy a matching pumps.
Strict procedures to purchase pumps. Also factual purchase pumps "three cards" that permit the promotion of agricultural machinery, production licenses and product inspection certificate, only three cards are complete before being eliminated to avoid the purchase of products and inferior products. |
