The cooling fan test method: 1.
1 current: the current in the continuous rotation measurement 1 3 minutes.
Speed: speed in continuous rotation measurement 1 3 minutes.
After 3 starting voltage: turn ON the switch 'ON', to be able to start the cooling fan operation voltage of 1.
4 power input: input power in the continuous rotation measurement 1 3 minutes.
5 lock current: can lock the cooling fan, in the fresh air of the current lock lock machine measurement 1 3 minutes.
6 air flow and pressure data measured according to the rules of 'AMCA standard' or DIN24163, determination of the data in the warehouse, double pressure and measured pressure warehouse 1 on each side of the pressure data.
7 noise standard: standard test reference DIN45635 noise, measurement in the soundproof room, put the microphone in the cooling fan a 2 meters.
The cooling fan protection test: 2.
Twist lock protect 2.
1 several cooling fan blades together fixed limit its rotation, if the cooling fan and electronic components are not damaged, rotational component of restrictions to loosen the cooling fan can automatically restart the rotation.
2 small current or with Auto start function of the cooling fan, the electric lock cooling fan blades rotating state, after 72 hours continuously, loosen the locked door leaf, the cooling fan automatically turned immediately, prove the wind fan without exception.
3 large current or without Auto start function of the cooling fan, not long time locking, damage or the cooling fan will overheat.
2 polarity protection voltage under normal conditions, if the power connection to the cooling fan electricity for 15 minutes, according to normal again when the power is the connection between, all functions will be normal. 2.
Free fall monomer by 600 mm high altitude down to 30 mm thick plank, the cooling fan 6 surface of any side and corner are amenable to drop test, and confirm that no damage.
Insulation resistance under the condition of 500 v direct current, frame and the anode resistance of not less than 10 m Ω 2 wire.
Dielectric strength in 5 ma leakage current, AC500V conditions for 60 seconds, the casing outside the cooling fan and the conductor is no exception, prove good insulation above is the cooling fan of some related technologies, the better the technical, quality, the better, it shows that the cooling fan wen ling chi car air conditioning cooling fan manufacturer is specialized in the production of research and development manufacture radiator cooling fan, dc cooling fan, ac cooling fan enterprise company, have YiRongChuan company has a high-quality research and development of management and technical team, the company has been committed to the standardization management, more than 100 outstanding assembler, adopted the means of standardized production, the implementation of standardized operation, and has perfect testing management, efficient the monthly production capacity of more than 1. 3 million units.
And can design for customers to develop personalized products and auxiliary cooling solutions.
Company to customer demand and needs as the guidance, in order to better serve global customers, YiRongChuan radiator cooling fan has obtained a series of safety certification, such as: CCC, UL, CE, ROHS, CUL, etc.
More than 10 years of growth and the large investment, has introduced high temperature aging equipment, constant temperature and humidity equipments, the normal temperature aging equipment, salt spray testing machine, balance machine, no ring chamber, PWM signal generator and digital oscilloscope, digital bridge, such as high-end equipment, guarantee the product reliability and stability.
Exquisite technology and strict requirements, bring you a more excellent products, is the right choice of major industrial cooling fan purchaser partners, welcome to talk about.
