Common steel wire rope electric gourds include CD1 electric gourd, MD1 electric gourd, micro electric gourd, explosion -proof electric gourd, etc. Which steel wire rope electric gourd may not be able to start in use in use. The following five cases are common: 1. If the wire rope electric gourd is placed for a long time, and the maintenance and maintenance is not good, it will cause braking, which will cause braking. When the wheel and end cover are rust, the brake wheel cannot be cut off, and the motor will make a "hum" sound. The solution at this time is: remove the brake wheel, clean the rust surface, and re -test. Second, the load is too large or the transmission machine is faulty. Generally, electric gourd matching motor power is reasonable, and heavy objects cannot be overloaded. If the electric gourd cannot be rotated, the load is unloaded first. If the motor can start normally, it means that the transmission mechanism such as the speedbox is faulty. Clear the fault. Third, check whether the power fuse is burned. If one phase is broken, the motor starts with a single phase, the starting torque is zero, and the motor cannot be rotated. A sufficient melting should be replaced. 4. The voltage of the power grid is too low. The startup torque is proportional to the square of the voltage. The accelerated torque cannot overcome the load torque. If the operating speed cannot be achieved, the power grid voltage should be appropriately increased. V. Short -circuit, grounding, or disconnection of the stator winding. When the winding is located at the floor of the floor, the wiring box should be opened to check. Not only does it check the motor during the disconnection, it should also check whether the control equipment wiring is correct. The head contact cannot be connected to the line. The sandpaper is applied to the seater traces of the contact of the contact device. At the same time, it is necessary to check the iron heart suction and disconnect. If there is a card resistance, the contactor is replaced if necessary. After the steel wire rope electric gourd strikes, the operation should be stopped immediately, a comprehensive shoulder rubbing, discovering problems in time, and fixing as soon as possible to avoid affecting the progress of the project and increasing costs.
