Introduction of safety protection level of pump motor

Motor is an indispensable component of the pump, of course, in addition to the diesel engine pump. In general, we are in the procurement of the pump will be asked what the customer needs to be equipped with motor, visible motor for the importance of the pump, today we come to a simple introduction about the pump motor safety protection level.
Motor safety protection models are generally IP beginning, such as IP54, IP44 and so on, we will use the * No. instead of these two numbers, namely: IP**.
Protection level:
0 no protection motor, no special protection, no test, but should be in line with 2.1
1 protection larger than 50MM solid motor can prevent large area of the body accidentally accidentally touched or close to the shell charged or rotating parts. Can prevent the solid foreign body into the shell diameter greater than 50MM
2 protection is greater than 12MM solid motor can prevent the solid foreign body into the shell diameter greater than 12MM
3 Protection larger than 2.5MM solid motor can prevent the diameter of more than 2.5MM of the tool or wire touching or close to the shell charged or rotating parts
4 motor protection is greater than 1MM solid can prevent the diameter or thickness of more than 1MM wire or strip touching or near shell charged or rotating parts
5 dust motor bear in any direction should be no harmful effects of splash
6 dust completely prevent the intrusion of foreign objects, and can completely prevent dust from entering.
0 no special protection for non protective motor
1 drop motor vertical drop should have no harmful effects
215 degree drop motor when the motor from the normal position to any direction tilt to 15 degrees in any angle, vertical water dripping should have no harmful effect
3 water spraying motor and the vertical line into the 60 degree angle range of the water spray should have no harmful effects
4 splash proof motor under any direction splash should be no harmful effects
5 anti water jet motor to bear any direction of water spray should have no harmful effects
6 the motor's water intake should not be harmful to the extent that the motor's water intake should not be harmful when it is subjected to strong waves or strong water jet.
7 anti immersion motor when the motor immersed in the provisions of the pressure of the water after a specified time, the motor's water intake should not be harmful to the extent
8 submersible motor motor under the conditions specified in the plant can be long-term diving. Motor is generally water tight type, then to some type of motor can also be allowed to enter the water, but should not be harmful to the extent.
