[Fluid News] Asian deep well pump in use, what data need attention? What data can be prepared in advance? What data may have an impact on the work after? For deep well pumps, the depth of the dynamic water level, the total length of the water pipe, the lift required for lift, the total loss lift, can all have a significant impact on the use of deep well pumps. So these data should be how to calculate? Deep well pump how to calculate more in line with the actual use? Deep well pump how to calculate 1, determine the type of deep well pump Deep hole pump according to the borehole diameter and depth of the initial selected model. If the borehole diameter is 200mm, only 8JD or SD8 deep well pump should be selected to maintain enough clearance between well and pump. 2, the water level drop According to the selected model, with reference to product samples, find out the rated flow Qe, according to the following formula to find out the water level when the flow down. SM = SqQe, where SM-level drop, m, SM ≤ H / 2. 3, the hydrodynamic level depth Hd = Hi + SM 4, deep well pump in the well the total length of the water pipe L = Ha + (1--2), where L- the total length of the water pipe, m. The calculated L value should not be greater than the maximum length of the wellhead given by the model pump in the product sample. 5, the total loss lift According to the diameter and flow of water pipes, found for every 10m long water pipe friction loss h value, then the total loss of water pipe: △ Hz = 0.1hL, where L-pipe total loss lift, m . 6, lifting the required lift Hx = Hd + △ Hz, where Hx - deep well pump to lift the required head lift wellhead. If the water is pumped to a certain height from the ground, then the above formula Hx plus pipeline above the ground water friction loss. 7, the impeller series and pump head Hx according to the determined to determine the pump impeller series, so that the rated lift of the pump is not less than Hx, that is, He = KHx. Where K is the reserve factor, about 1.1--1.2. Determine the water level, the depth of the water level, the total length of the water pipe, the total loss lift, lift required lift, the number of impeller and pump lift these data for the use of deep well pump significant, which may not only affect the deep well pump Selection, but also may affect the actual product efficiency. As the saying goes, a good start is half done, and if it is possible to prepare for advance work, it will certainly have a positive impact on production and work.
