The IP protection waterproof rank test methods, the finishing

IP protection grade is the electrical classification according the characteristic of the dust-proof and moisture. The waterproof level according to the waterproof effect can be divided into eight level, eight levels of test methods as shown below,

note: our company agent JAMICON kaimei cooling fan and San Ace sanyo industrial cooling fan is also have waterproof function well, welcome to test well, true gold fears not the fire oh, but I still need to pay attention to our how much is the waterproofing of the cooling fan to contrast with inspection method should be to!

(1) the IPX 1

the method name: vertical drop test

testing equipment: drop test apparatus

sample place: according to the normal work of the sample position is put on the samples with the rotation of the 1 r/min, sample top to drop port distance not greater than 200 mm test conditions: drops of water to 10. 5 mm/min

duration: 10 min

2 IPX 2

the method name: tilt 15 ° drop test

testing equipment: drop test apparatus

sample placement: make specimen of a plane and vertical into 15 ° Angle, sample top to drop port distance not greater than 200 mm. After each test the one side, in another side, a total of four times.

test conditions: drops of water amount to 30. 5 mm/min

duration: 4 x 2. 5分钟( A total of 10 min)

(3) the IPX 3

the method name: water spray test

test method:

a. Tube type water spray test

testing equipment: pendulum tube drench water splashing water test device

sample placement: selecting the appropriate radius of tube and in arranging the sample mesa height diameter position, put the sample in sample stage, make the distance from the top to the sample water is not more than 200 mm, samples not rotating.

test conditions: water flow by arranging the blowhole is counting, every hole is 0. 7 L/min, water spray, 60 ° to each side of arranging the middle segment of blowhole water spray to the samples. Samples of subjects in arranging the semicircle center. Tube is placed in vertical sides is 60 °, 120 °. Swing at a time ( 2×120°) About 4 s

test time: continuous rain water 10 min

b. Nozzle type water spray test

testing equipment: hand-held shower water splashing water test rig

sample placement: make the test at the top to the handheld shower sprinkler parallel distance between 300 mm to 500 mm

test conditions: the trial should be installed with a balance weight, water flow of 10 L/min

test time: according to the shell surface area calculation, test sample for 1 min (per square meter Not including installation area) Pendulum tubular splash water test

test equipment and sample placed: with the IPX of 3 a, all the same;

test conditions: in addition to the above conditions after, and the IPX 3 a, all the same; Water area for arranging the midpoint 90 ° to each side of segmental arc blowhole of hydraulic spray it to the samples. Samples of subjects in arranging the semicircle center. Swinging 180 ° to each side of tube is placed in vertical, a total of about 360 °. Swing at a time ( 2×360°) About 12 s

test time: with the IPX 3 a, all the same, The 10 min) 。 Nozzle type splash water test

test equipment and sample placed: with the IPX 3 b are the same;

test conditions: down devices are installed on the belt balance the weight of the baffle, the rest is the same as the IPX 3 b of all;

test time: with the IPX of 3 b are the same, that is calculated on the shell surface area test sample, every square metre is 1 min ( Not including installation area) At least 5 min

5] IPX 5

the method name: water spray test

testing equipment: nozzle's diameter is 6. 3 mm

test conditions: make the test sample to water-jet is 2 apart. 5 m ~ 3 m, water flow is 12. 5 L/min ( 750升/小时)

test time: according to the shell surface area calculation, test sample for 1 min (per square meter Not including installation area) At least 3 min

[6] the IPX 6

the method name: strong water spray test;

testing equipment: water orifice diameter of nozzle to 12. 5 mm

test conditions: make the test sample to water-jet is 2 apart. 5 m ~ 3 m, water flow is 100 L/min ( 6000升/小时)

test time: according to the shell surface area calculation, test sample for 1 min (per square meter Not including installation area) At least 3 min

once the IPX 7

the method name: short water immersion test

test equipment and test conditions: leaching tank. Its size should be make the sample in the leaching tank, the distance to the surface at least 1 m at the bottom of the sample. Sample at the top of the distance to the surface at least 0. 15 m

test time: 30 min

being IPX 8

the method name: continual diving test;

test equipment, test conditions and test time: by the supply and demand, Buying and selling) The two sides agreed that the severe degree should be higher than the IPX 7.

note: in addition, many outdoor use electronic products also emphasize the floating ability.

Many of our low-demand customers often go to the electronics market or the so-called wholesale department to buy cooling fans.

Automobile radiator fan factory is a cooling fan manufacturer integrating Ru0026D, production and sales.
Recently, we dealt with a case of changing the installation method of the cooling fan, which has a great impact on the cooling fan.

During normal use of any electronic product, due to the effect of current, there will be varying degrees of temperature rise inside the device, and when the temperature rise of the device exceeds a certain range, its life will be attenuated to varying degrees (for a long time, The safety of equipment operation will also be reduced).
Car cooling fan working position and its principle: cooling fan working principle 1.

The comprehensive laboratory of the automobile radiator fan factory has introduced new equipment-the thermal shock test box.
The commonly used cooling fan voltage is generally 12V, but some customers' products, such as temperature-controlled cooling fans, set a lower voltage for the cooling fan at low temperatures.
When we choose a cooling fan, especially for certain voltages that are not very stable or have several different voltage gears for speed adjustment, we need to understand the voltage range of the cooling fan, such as a cooling fan that works with a 12V DC voltage.
