Precautions to be confirmed before purchasing a cooling fan

The following parameters must be confirmed when purchasing cooling fans for non-professional people. ( Professionals can directly choose the model parameters they need. )

I.Fan size:length, width and thickness.Taiwan's three major general sizes are:280 x 280 x 80 mm, 225 x 225 x 80 mm, 220x60mm, 200 x 200 x 60 mm, 180 x 180 x 60 mm, 172x51mm, 172 x 150 x 55 mm, 172 x 150 x 51 mm, 172 x 150 x 38 mm, 150 x 150 x 51 mm, 150 x 138 mm, 135 x 135 x 38 mm, 120 x 120 x 38 mm ( 25 ), 110 x 110 x 25 mm, 92 x 92 x 38 mm ( 25 ), 80 x 80 x 80 x

II.Fan Voltage:AC 110 V 220 V 380 V; DC 5V, 12V, 24V, 48V; If you have any special voltage requirements, please specify that Taiwan's Three Giant will give you a private subscription.

3.Fan bearings:oil bearing and double ball bearing. Difference:Life expectancy is different; The theoretical life of oil bearing is about 30000 hours, and that of ball bearing is about 50000 hours, but the price of ball bearing is more expensive than that of oil bearing.

Four, fan speed:general fan speed is divided into high and low three specifications. The higher the speed, the greater the air volume, the greater the static pressure, the greater the noise, the greater the current and power, and vice versa.

V.Fan interface:sub-leads and plug-in terminals. It is necessary to confirm which interface to select, and if it is a lead, specify the lead length. Generally, the default length of 30cm is not specified.

VI.Fan Certification:Whether there are environmental protection requirements and whether relevant certification is required. If necessary, specify before purchasing.

Seven, fan accessories:whether to match the net cover; The net cover is an iron net, a plastic one-piece net, a plastic three-in-one net, or a filter net group.

VIII.Other parameters of fan:such as current, voltage, power, air volume, noise, etc.Are there any specific requirements? If so, please provide detailed data as far as possible. It should be emphasized that many customers require the maximum air volume, the minimum noise and the maximum wind noise.The two are contradictory.Please choose a balance between air volume and noise.

Nine, other special requirements:such as waterproof and moistureproof, high temperature resistance of iron leaves, capacitance, high voltage resistance, temperature control, whether to attack teeth or not; Is there a requirement for the number of blades:five, seven or nine.

Some Matters Needing Attention in Storage, Installation and Use of Cooling Fan

First, the cooling fan should be stored in a dry environment to prevent the motor from being affected with damp. When the fan is stored in the open air, there should be defensive measures. Do not use in flammable gas and any harmful environment; Do not touch the blade or wind the fan around the power cord or pull the power cord, the axis and power cord will be damaged.

2.Please use it within six months after purchase.Long storage time will affect fan performance due to storage environment. Please avoid dust, water drops and bugs from entering, which will affect the service life and the production of defective products.

Three, when the fan is in operation, do not attempt to lock the fan for a particularly long time, this will burn the fan due to continuous stop and high heat.

Four, when handling or operation, if the fan falls from the height of 60 cm, it will have some influence on the balance of the blade, especially the ball bearing will not fall off. When installing the fan, pay special attention to noise caused by resonance or vibration.

Five, the lock shell screw torque shall not exceed 4 kgf; Please do not block the fan with screwdriver, iron bar, etc.This will damage the fan. Be sure to install fan protection accessories, which may hurt your fingers when the fan is running at high speed.

Six, only under the condition of fan completely normal operation, at the same time to ensure that the power supply facilities capacity is sufficient, voltage stability, it is forbidden to run without phase, power supply lines must be dedicated lines, should not use temporary lines for a long time.

Seven, cooling fan in the process of operation found abnormal sound, motor serious fever, shell charged, switch tripping, can't start and other phenomena, should immediately stop for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan.After maintenance, the fan should be put into trial operation for about five minutes to ensure no abnormal phenomenon.

Eight, the use of cooling fan environment should always keep clean, fan surface clean, inlet and outlet should not have sundry, regular cleaning fan and pipe dust and other sundry.
