Fluorine plastic magnetic pump troubleshooting

Fluorine plastic magnetic pump, an important part of the pump industry, her use is very wide, set a lot of advantages in one, but the tool is good, not good, but also can not play his best advantage Let me introduce you to the troubleshooting method of fluorine plastic magnetic pump so that we may encounter a similar problem in use and can be better solved. Fluorine plastic magnetic pump troubleshooting (1) Shaft broken off fluorine plastic magnetic pump shaft material used is 99% alumina ceramic, the main reason for the shaft is broken, because the pump runs dry, the shaft bearing dry grinding and torsion Off. Open the pump inspection can be seen when the bearing has been seriously damaged to prevent the pump broken off the main method is to avoid the air pump running. (2) bearing damage Fluoroplastic Magnetic pump bearings are made of high-density carbon material, in case of pump water or pump impurities, it will cause the bearing damage. Cylindrical coupling inside and outside the rotor between the coaxial requirements if not guaranteed, it will directly affect the bearing life. (3) Lack of headache The reasons for such failure are as follows: there is air inside the transmission medium, the impeller is damaged, the speed is not enough, the proportion of the delivered liquid is too large, and the flow rate is too large. (4) The main reasons for the lack of flow caused by insufficient flow are: impeller damage, speed is not enough, the lift is too high, the tube is clogged with debris, etc. (5) Fluorine plastic magnetic pump can not play the liquid. Fluorine plastic magnetic pump can not hit the liquid pump is the most prone to failure, and its reasons are more. He is unlike the self-priming principle used in fluoroplastic self-priming pumps. First of all, check whether the pump suction pipe leaks, check the suction pipe air is discharged, fluorine plastic magnetic pump fluid volume is sufficient, inhalation tube whether there is debris clogging, check whether the pump is Reversal (especially after replacing the motor or overhauling the power supply line), you should also pay attention to whether the pump suction height is too high. If the above inspection still can not be solved, the pump can be disassembled and checked to see if the pump shaft is broken. Check whether the moving ring and the static ring of the pump are intact, and whether the entire rotor can move in a small amount. If the axial movement difficulties, can check whether the carbon bearing with the pump shaft is too close. It is noteworthy that, fluorine plastic magnetic pump repair several times to check the problem, should pay attention to the work of the magnetic coupling is normal. Bearings, inner magnetic rotors and spacers generate heat during operation, which increases the operating temperature and on the one hand reduces the power delivered and on the other hand creates a great deal of hassle for the fluoroplastic magnetic pumps that convey easily vaporised liquids . Magnetically transmitted power with temperature increases is a continuous decline in the curve, usually below the working temperature limit of the magnet, the decline of its transmission capacity is reversible, but above the limit temperature is irreversible, that is, the magnet cooling After losing the ability to pass the transfer can no longer be restored. Under special circumstances, when the magnetic coupling slips (out of step), the eddy current heat in the spacer increases rapidly and the temperature rises sharply. If it is not processed in time, the magnet will demagnetize and make the magnetic coupling fail. Therefore, fluorine plastic magnetic pump should design a reliable cooling system.
