Explosion-proof motor explosion-proof principle and inspection methods

Explosion-proof motor explosion-proof principle and detection methods. The explosion-proof principle of explosion-proof motors is: when an explosion occurs inside the motor, firstly, the motor casing has sufficient strength to withstand the internal explosion pressure without deformation or damage. Using the gap cutting principle, when an internal explosion occurs, the fire generated passes through the gaps of all joints of the motor casing, the joints cool the flame, reduce the flame propagation speed, and prevent the flame and explosion products from spreading outwards through the casing gaps, preventing external explosive mixtures. Let's learn about the explosion-proof principle and inspection methods of explosion-proof motors!

Operating conditions for explosion-proof motors and precautions for low-temperature starting

Operating conditions for explosion-proof motors: altitude below 1000 meters, ambient temperature -15 to 40 degrees, suitable for locations without explosion-proof requirements. When using explosion-proof motors in low-temperature environments, higher starting requirements are needed. Failure to follow the starting requirements for explosion-proof vibration motors may lead to problems such as cracked insulation wires. Let's learn about the operating conditions of explosion-proof motors and what to pay attention to during low-temperature starts!

What are the precautions for using and maintaining explosion-proof motors?

Compared with ordinary motors, the structural feature of explosion-proof motors is that the contact surfaces between the bracket and the end cover, junction box, junction box floor, cover plate, etc. are all set as explosion-proof surfaces. The joint surfaces of explosion-proof motors and ordinary motors have no substantial difference, but in order to meet the higher sealing requirements, the fitting area (such as longer cracks) is increased, and the fitting accuracy is improved.

What are the classifications and characteristics of explosion-proof motors?

Explosion-proof motors are motors that can be used in flammable and explosive environments without producing sparks during operation. They are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, they are widely used in textile, metallurgical, urban gas, transportation, edible oil processing, papermaking, and pharmaceutical industries. Explosion-proof motors are mainly used as power equipment to drive pumps, fans, compressors, and other transmission machinery.

Precautions for using explosion-proof motors

Explosion-proof motors are a type of hazardous special motor equipment. Once rust and rust spots appear on the explosion-proof surface, causing poor contact at the contact surface, harmful media will take the opportunity to enter, corroding internal parts and the insulation of the windings. Once an explosion-proof motor loses its explosion-proof function, the consequences are unimaginable. Therefore, it is of great significance to promptly discover, repair, and eliminate faults in explosion-proof motors.
