Reducer, motor protection class IP on behalf of the mean

PROTECTION class USES the INTERNATIONAL ELECTROTECHNICAL COMMISSION (IEC) recommended standard of IP x grade, different installation place, is not the same grade, IP (INGRESS PROTECTION) PROTECTION grade system is made up of IEC (INTERNATIONAL ELECTROTECHNICAL appointed the draft. Electric appliance according the characteristic of the dust-proof and moisture to be graded. In the rating standard, the "x" is two digits, the first said to solid protection grade, the second said protection grade of the liquid. Solid protection grade seven class, use a scale of 0-6 respectively; Liquid protection grade nine grades, with 0 and 8, respectively. Details are as follows:

The meaning of the first digital IP behind

0, no protection, no special protection

1, to prevent greater than 50 mm diameter solid foreign body into the chassis, can prevent the body of the large area such as hand accidentally hit a shell charged or moving parts, but it can't prevent conscious close to these parts.

2, can prevent the diameter greater than 12 mm solid foreign body into the chassis, can prevent the fingers touch the shell charged or moving parts.

3, can prevent greater than 2.5 MM diameter solid foreign body into the chassis, can prevent the thickness (or diameter) is greater than 2.5 tools, such as metal shell charged or moving parts.

4, to prevent greater than 1 mm diameter solid foreign body into the chassis, can prevent (or diameter) is greater than 1 mm thickness of tools, such as metal shell charged or moving parts.

5, can prevent dust entering to affect the normal operation of the product, completely prevent the shell hit a charged or moving parts.

6, completely prevent dust from entering the, completely prevent the shell hit a charged or moving parts.

The meaning of the second digit IP behind

0, no protection, no special protection.

1, drip-proof, vertical drop of water should not directly into the product inside.

2, 15 ゜ drip-proof, with a plumb line into a drop of water shall be within the scope of a 15 degree Angle can't directly into the product inside.

3, water spray, water, and the plumb line into 60 degree Angle within the scope of the spray water should not directly into the product inside.

4, splash water, splashing water on any direction products should be no harmful effects.

5, water proof, any direction of hydraulic products should be no harmful effects.

6, violent waves or powerful hydraulic products should be no harmful effects.

7, prevent flooding, the products within the prescribed time and pressure submerged in the water, into the water to the product should have no harmful effects.

8, scuba diving, products in the provisions under the pressure of the long soak in the water, into the water to the product should have no harmful effects.

For example: Ip68:

Out the six said the dust (dust) absolutely, the eight said the top waterproof, the level of motor is completely sealed, work underwater would be all right.
