Mzada radiator fan is not required by customers. We usually use 150mm without terminal wire. In order to reduce the working hours of manual wire bonding, most customers require a terminal wire for the fan, but many customers do not know the terminal. Model
Commonly used terminal models are 1.25 end, 2.0 end, 2.50 end, 2.54 end or 2510 end. The terminal picture is as follows
There are other special terminals, such as 3.96 end, aircraft head terminal, etc. If the customer needs it, the technology can cooperate with the customer to make such a terminal wire to the Mzada radiator fan.
The bearing of the Mzada radiator fan is the cylindrical fitting that fixes the rotor core in the outer frame tube. The type of this bearing is widely used in the entire Mzada radiator fan industry. The special patent bearing has magnetic bearing, hydraulic pressure. Bearings, of course, there are some homemade bearings that are not ideal, so I will not list them here.
There are three types of universal bearings, double ball bearings, single ball bearings and oil-impregnated bearings. In fact, single ball bearings are now used in fewer and fewer factories because of the unstable structure.
Some of the guests said that they want bearings. In fact, they mostly say that they want double-ball bearings. They mean that oil-bearing bearings are called refueling, and there is everything in the oil pressure. When the customer needs samples, the technology will carefully and carefully ask.
General Mzada radiator fan suppliers will give customers a specification, which has a noise value. What is the size of the noise value? How far is it from the test equipment? Many people think that it is close to the noise measurement. Data obtained by the device
In fact, this is not the case. The ordinary fan is the 1M test noise value from the sensor, and the Mzada radiator fan is used for the so-called non-sounding room test. The technology's soundless room is suspended, and the background noise is 16db. Currently the most advanced equipment, commonly used is 18.5DB.
In addition, for some miniature fans, because of the small size, 1M test noise, the sound will be less than 16db, so we will use 30cm test noise, the technology will be described in the specification
