First, choose the right pump flow Pump flow, that is out of water, the general election should not be too large, otherwise it will increase the cost of purchasing the pump. Should analyze specific issues, such as the user's own draft with the self-priming pumps, flow should try to choose a small number of; such as user irrigation submersible pumps, you can select the appropriate flow some. Second, the extended service life of the pump: 1, for submersible pumps Should do the necessary checks before starting: the rotation of the shaft is normal, 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 ± 5% of rated voltage. In addition, the position 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 clogging the pump or suspension of imports, while resulting in a sharp drop in water no water pumping even come. 2, for the self-priming Should be placed as far as possible in a well ventilated place to run, in order to facilitate rapid cooling, reduce motor temperature. Otherwise, the long-running, easy burning motor. If a farmer in the use of pump, because there is no remove the plastic film covering the motor, resulting in motor overheating, burned out coils. 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 parts. Under normal circumstances, the pump starts after 3-5 minutes the water should be, or should be shut down immediately checked. 3, pump repair When the pump in the event of a fault, should not it-yourself demolition. Removing yourself because, first, I do not know where the fault caused by blindly indiscriminate demolition of a pass; Second, no special tools which often damages the integrity of the original parts. 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, should repair the pump once every six months, to eliminate with "sick" work. 4, the non-use of storage In the non-use period, should be promptly lifted off the water pump, the air pump and 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 bearing lubricant 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. |
