For the vortex pump click View and fouling problems harm, I hope we can have a little more in-depth understanding and use of goods and maintenance more have heart hand. First, the vortex pump motor problems viewing methods 1. External observation: that is to look at the junction box, winding end whether the charred appearance, odor, etc. and presence. 2. The electricity experiment: that is measured by ammeter, if one phase current is too large, then the stated problem. 3. The voltage drop method: that is, the three windings in series, and then pass into the low-voltage alternating current security, if reading small, then there is a short circuit appearance. 4. Bridge View: winding DC resistance were measured, the difference is not more than 5%, if more than the stated short-circuit representation. 5. Check the temperature probe method: that is to let the whirlpool pump load running 20 minutes, and then view the temperature of the winding section is not normal. Second, the vortex pump vortex pump damage scaling in the use of the process, because the technology of water, calcium and magnesium hardness, PH, conductivity, total alkalinity and temperature, etc., will occur fouling appearance. Once the pump render the representation, it will certainly damage its formation, are: 1. The cost will increase, as well as pollution load of chemicals. 2. will increase the number of unplanned downtime, and the formation of a continuous production, thereby affecting the production of power, and add costs. 3. Simple trouble making equipment presents production, increasing energy loss of the device, and then shorten the service life of the device. Vortex fan, whirlpool fan, vortex pump www.mingxintm.com
