BSBY_f010 DC fan manufacturers brand [motor] Shenzhen Xin Xin speeding speeding Motor Co., Ltd. has always adhere to the "people-oriented" management philosophy and "pragmatic innovation" concept of development, the implementation of scientific management. Products are exported to foreign markets, and to require the production of various products according to customer's special. The company's own MDOVPD (Modern speeding) brand in the community has been recognized by our customers and trust. The product has passed the UL, CE, ROHS, CCC and other safety certification, and is widely used in communications equipment, network chassis cabinets, automation machinery, medical equipment, stage equipment, LED display, welders and other equipment services. DC fan manufacturers of consumer choice is a lot of trouble problem, because if the manufacturers have not selected, then the product will guarantee bad to say. So manufacturers of choice is very important, DC fan manufacturers Xin speeding is everybody trusted brand manufacturers, their products are superior quality, perfect service, there is the price. Then we talk about small series to give relevant expertise on the fan bearing vibration: on the fan bearing vibration value of the maximum allowable number of questions: (1) when using the effective display of bearing vibration speed: 11mm / s. (2) for the following values ??bearing amplitude display: motor synchronous speed of 3000 rev / min: The maximum allowable value: 0.1mm (double amplitude) motor synchronous speed of 1500 rev / min: maximum allowable value: 0.2mm (double amplitude) motor synchronous speed of 1000 rpm / min: maximum allowable value: 0.31mm (double amplitude) motor synchronous speed of 750 rev / timeshare: the maximum allowable value: 0.4mm (double amplitude) motor synchronous speed 600 r / time: the maximum allowable value: 0.5mm (double amplitude) motor synchronous speed of 500 rev / min: The maximum allowable value: 0.6mm (double amplitude) fan bearing temperature is normal for ≤70 ℃, if Once raised to 70 ℃, electronic control should (will) alarm. You should find out the reasons, first check whether the cooling water is normal? Bearing oil level is normal? If you can not find a reason, bearing temperature quickly rose to 90 ℃, electronic control should (will) again alarm, stop signal. Fans month after the first run, you should change the oil again to update (or fat) should be replaced after each subsequent addition to the overhaul, but normally 1 to February change the oil (or fat), can be replaced according to the actual situation lubricating oil (or grease). Fan drive, stop or during operation, such as found irregularities should be checked immediately, DC fan manufacturers to remind you if the check discovered glitches should be trying to identify the reasons for cancellation. Found great fault (such as fans severe vibration, shock, bearing temperature rise dramatic rise, etc.) should be immediately stopped and checked.
