Motor burn the reason is many, but the proper use of water pump is one of the important reasons. When using water pumps, after turning on the power supply, carefully observe the workings of the pump, the water should be continuous uniform, pump no vibration and noise before use. If all of a sudden stop in the run, should immediately disconnect the power supply, check the reason. Pump starting time of two intervals, should is limited to pump all the water in the back. Such as early to start, because too much resistance and water hammer occurs in the pipe and burning motor. In addition, if the pump is installed in the well, to pay attention to the flow of the pump shall conform to the normal water yield well, otherwise it will cause an empty machine running, burning motor. In order to ensure the normal operation of the pump, and also response to check it again before use. 1, using the multimeter, check whether the water pump motor winding is open circuit. Its insulation condition can be used for 500 v megohmmeter measurement, insulation resistance is lower than 0. 5 ohms, pumps cannot be used. 2, remove filter, turn the pump shaft is flexible, such as is not flexible, should adjust the rear can use. 3, gate the fuse capacity to choose whether or not appropriate, cannot use other wires to replace the fuse. 4, put through power supply, check whether the impeller is normal (Power on time no more than 3 ~ 5 seconds, otherwise easy to burn out motor)。 the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
