Are explosion-proof motors afraid of water?
Thread Content
Normal explosion-proof motors have fairly good sealing properties; since the installation location is next to a pool, it’s not clear whether such motors can be used in this environment. It’s better to choose another type of motor
Explosion protection and protection rating are two different things; it is recommended to use a protection rating of IP45 or higher
To add, an explosion-proof motor, as the name suggests, is designed to prevent combustible gases from entering; you are referring to humid environments.
If it can prevent flammable gases, it should be able to keep out water as well, right?
This is related to the explosion-proof rating. The vast majority of motors in refineries are installed outdoors and can withstand heavy rainfall, but in our plant, there was recently an indoor pump that suffered damage due to water entering the motor as a result of accidental activation of the fire suppression system. It was only later that it was discovered that the explosion-proof rating of that pump was too low; the equipment in question was imported from Germany over a decade ago – who would have thought?
Yes, in outdoor environments with harsh conditions, a model with an IP65 protection rating can be chosen; this rating covers both explosion resistance and water resistance
Explosion resistance does not mean water resistance; I’ve encountered that before. A new workshop has been built; since there is no warehouse, the mixers and pumps are stored outdoors. After being exposed to sun and rain for two months, the rear swing cannot be raised due to insulation issues, making it impossible to conduct a test drive. . . I had to take everything off and heat it with an iodine-tungsten lamp for a whole day to fix the problem; I almost got scolded to death. The motor for water intake has an explosion protection rating of IIB T4; as long as it is not exposed to water for extended periods (by using a rain cover), it can be used right next to a pool without any problems
The rainwater isn’t a big problem; just rinsing it with water might burn it~~~
You have mixed up the concepts. The definition of explosion-proof equipment is: electrical equipment that will not cause ignition in the surrounding explosive environment under specified conditions. So it has no direct relation to whether it’s by the pool or not. Water resistance should refer to protection levels, such as protection against splashing water, spraying water, short-term immersion, long-term immersion, dust protection, and so on.
Yes, in outdoor environments with harsh conditions, a model with an IP65 protection rating can be chosen; this rating covers both explosion resistance and water resistance
Generally, IP55 ratings are fine for most cases. The key question is what the IP rating of your explosion-proof motor is, and what are its ratings for water and dust protection
