Let's talk about CT4 motor usage and maintenance?
Compared with ordinary motors, the structural features of the CT4 motor are that all contact surfaces of the connecting parts of the bracket, end cover, junction box, junction box bottom plate and cover plate are set as explosion-proof surfaces. The joining surfaces of the CT4 motor and ordinary motors have no substantial difference, but in order to meet higher sealing requirements, the mating area (such as longer cracks) is increased, and the mating accuracy is improved. This part uses sealing glue, rubber gaskets, etc. In addition, the junction box should be tightly isolated from the inside of the shell. In order to prevent the "explosion" pressure inside the motor from detonating the shell, the strength and thickness of the materials used for the bracket, end cover, and junction box should be very high. In addition, these parts have undergone pressure resistance tests (usually internal resistance tests). Only after passing the test can they be assembled. Regarding the use and maintenance of CT4 explosion-proof motors, what relevant issues need to be paid attention to? Let's take a brief look.
(1) The type of explosion-proof CT4 motor should be selected according to the usage environment.
(2) Strictly set short-circuit, overload, overheat, and insufficient protection as needed, and regularly check whether these protection devices are effective.
(3) Non-professionals are prohibited from disassembling any parts of the motor.
(4) Connect the power cord according to the following steps: After removing the junction box cover, loosen the junction box cover, remove the rubber pad at the entrance of the junction box, and clamp the two parts on the cable.
CT4 motor The inner hole of the rubber pad should be the same as the outer diameter of the cable, and there should be no large gaps, otherwise, when the wiring tube is pressed down, the rubber pad and the cable will not be sealed, so when the junction box explodes, the motor will explode outside, thus losing the explosion-proof function. The cable at the entrance of the junction box is introduced into the box body, and the corresponding terminals are wound with three cores (the grounding core should be wound on the grounding screw of the mining motor), and each iron core should be rounded in two arched washers, and the terminal nuts should be tightened. After connecting the cable, install the rubber washer, install the junction box, tighten the screws, press the rubber ring with the end face of the connecting end, and make the cable completely engaged.
When the explosion-proof CT4 motor needs to be disassembled, special attention should be paid to protecting the explosion-proof surface and the winding from impact. If multiple units are disassembled at the same time, the disassembled parts should be stored separately and should not be confused. If the disassembled parts are stored for a period of time, the explosion-proof surface should be given necessary rust prevention treatment.
