Buy QJ deep well submersible pumps do not have to pursue high lift
   In the sales of submersible pumps, often encounter some customers how to choose the pump, in addition to some of the common sense we know, a large part of the customers prefer the selected head higher than the actual use of lift, that this will be more insurance , Will be foolproof, in fact, this is not only unnecessary, and may cause damage to the pump. Here I come to explain to you the disadvantages of doing so.
 1, Shanghai Weihu pump produced by the deep well submersible pump will not virtual standard to 175QJ10-100, for example, flow in the rated flow of 10 square cases, the lift can certainly reach 150 meters 1 meter will not be less. There are many users afraid of the way up to the nameplate of the standard way, here, please rest assured. Now there are indeed many South manufacturers in pursuit of profit virtual standard, disrupt the market order, QJ submersible pump is not the case.
2, the actual use of head and rated head too much difference, will cause the motor overload, which may cause the motor cable package burned. For example, customers want to show the pump to play 80 meters, in fact, choose the pump 200QJ40-78 on it, the result is selected 200QJ40-117, in which case the lift is much smaller than the rated head, it will cause the motor overload, that is, We commonly known as the "suffocation pump", causing the motor burned, more harm than good.
 3, the selected submersible pump in the same flow conditions, the higher the higher the motor, the greater the power consumption. Or give the example above, 200QJ40-78 submersible pump is equipped with a 15KW motor, 200QJ40-117 with a 22KW motor, the greater the cost of higher motor. So the election submersible pump, then the best fit, no need to choose too much, resulting in unnecessary losses.
