That means to keep the machine protected routine repairs to extend the life. Although the machines are "dead", it requires people to operate it can be used, but we careful maintenance, in order to extend the life of the machine. When we buy a machine DG12-25X12 multistage centrifugal pumps, are durable to consider whether this thing? So that resistance is not durable machine main thing is to see if you know how to do maintenance on the machine, this little trick than any other factors useful. So mine multistage centrifugal pump motor spindle how to maintain it? Fine extension NC to answer your questions with a long mining multistage centrifugal electric spindle life DG25-30X5 To multistage centrifugal pump, maintenance is a very key issue. Mainly to the following aspects: First, can not occur in the case of collision: collision can be said that the centrifugal electro-spindle is the most damaging, especially steel material gong gong copper materials if the lateral collision, then also very deadly, light, then the spindle will sound phenomenon, heavy, will get stuck, bearing damage. The most common reason for the collision of four: 1, no amount of good knife, put a knife is shorter than the workpiece to be machined, the workpiece spindle nut hit. 2, the knife did not set the spindle directly tie down. 3, novice operation was not careful enough, or shake the wrong axis, for example, that the election process after the Z-axis, to shake up the results the election to X or Y, the result of a direct hit piece. One. Product Description 1 Overview: D-type pump for conveying solid particles, liquid water temperature is below 80 ℃ or physical and chemical properties similar to water, suitable for mining and urban water supply and drainage pumps for use DF lose -20 ℃ ~ 105 ℃, solid particles, liquid, corrosive imported pumps allow pressure 0.6MPa DM-type pump for conveying solid particles content not more than 1.5% neutral mineral water (particle size less than 0.5 mm), and the like Other sewage DG12-25X11 multistage centrifugal pump transmission medium temperature is not greater than 80 ℃, suitable for steel mills, mine drainage, sewage, transportation and other occasions. 2, the performance range: flow Q: 6.3 ~ 600m3 / h Head H: 17 ~ 850m3, Model Description: 100 D 16 * 3 100 is a pump inlet diameter is 100mm D is a multi-stage centrifugal pump 16 is a single-stage designed head two , D series multi-stage centrifugal Features: 1, hydraulic model of advanced, high efficiency, wide range of performance. 2, the pump runs smoothly, low noise. 3. Seal with soft packing seal or mechanical seal, seal safe, reliable, simple structure, convenient maintenance. 4, the shaft is fully sealed structure to ensure no contact with the media, does not rust, long life DG12-25X12 multistage centrifugal supply pump (certified), centrifugal pump provided by Anguo City Pump Co., Ltd.
