Auto cooling fan fan - — Function better
wenling chi automotive air conditioning manufacturing co. , LTD is a professional manufacturer of cooling fan, so a good product is definitely not good ball bearing role, tong chi car cooling fan fan function well?
the fan bearing system generally suggest zui good use ball bearings, because the life of heat fan fan often depends on the reliability of the bearing, ball bearing system has been proved to have the characteristics of rate and low calorific. Ball bearing rolling friction, the metal bead rolling, contact surface is small, small friction coefficient; And oil bearing for sliding friction, contact area is large, use for a long time, after oil volatilization, bearing is easy to wear and friction coefficient is big, the noise caused by the late life is short.
with long time of operation, the bearing inner oil can evaporate and dry, the friction coefficient increases, fan operation affected, may appear different sound, speed slow don't even turn phenomenon. And auto cooling fan fan ball instead of sliding friction, low friction coefficient and overcomes the drawback of the coefficient of friction can become, and running stability is strong, relatively is much longer service life.
wenling chi automotive air conditioning manufacturing co. , LTD. , focusing on the cooling fan of the research and development, production and sales, after years of research and design of the cooling fan experience, let tong chi every product can products in good condition, with the customer together, good corporate image, strict team spirit, providing customers with zui service, let the radiator products of the company in the industry has achieved fairly good reputation and credibility.
