0010010 nbsp; 0010010 nbsp; 0010010 nbsp; GreenhouseGreenhouse motorI believe that many greenhouse users have begun to use it. The operation and use of greenhouse motors are actually more convenient and fast, and they will not be so troublesome to use. However, we need to make a careful selection when selecting the greenhouse motor products, because only in this way can we ensure that our subsequent work will not cause losses due to errors in the greenhouse motor, so how can we judge the goodness of the greenhouse motor Bad? Today, Weifang Liwang Electric Co., Ltd. will introduce you.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1, you can connect the positive and negative poles, it will be very difficult when you screw it by hand The large resistance clarifies that the line is normal, otherwise there is a break point.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2, rotate the greenhouse motor by hand, if you feel there is significant resistance , It means that there is a short circuit point in the greenhouse motor. (The transition is stable to normal).

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3. Investigate the commutation sparks when the power is turned on, there are no sparks, there are little sparks For better results, the sparks are poorly connected, and the appearance of ring fire cannot be used. (The life span will be shortened relatively quickly)

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 4, DC high-power greenhouse motors run until the temperature rise is stable and punctual The meter measures the resistance of the winding. Usually from a few tenths to a few ohms.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 5 After running to a stable temperature rise, the surface temperature of the motor in the greenhouse should not be higher than { {5}} degrees Celsius. If it is higher than this value, the temperature rise of the motor is unqualified.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 6, add an additional voltage, measure the speed, and the deviation from the indicated speed should not be higher than 10.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 7 plus 1. 2 Voltage, run for 2 minutes and investigate for abnormalities.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 8, DC high-power greenhouse greenhouse motor meter measuring commutator Inter-voltage, if there is the same rule between the voltage between two pieces, clarify that the winding is normal.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; If you want to keep your greenhouse products in a good working state, daily installation and maintenance work Don't slack off. The above is the installation and disassembly inspection work of the greenhouse greenhouse motor shared by Weifang Liwang Electric Co., Ltd., I hope to help you!
