SX2010 cooling fan performance, use, packaging instructions, quality control:

Performance: The 2010 fan designed and manufactured by our company adopts high precision injection moulds to ensure the high accuracy of the products, making the fan more quiet, longer life, larger air volume and more reliable. At the same time, the fan motor is filled with motor components, and the IP68 class waterproof fan can be used in underwater saline-alkali, oil pollution and corrosive environment. Annual work, the use of international bearings, Japan NMB, to ensure that fans can work reliably for a long time, fans designed overpressure and overcurrent protection

The blocking function, if the fan blade is blocked by foreign matter in the work, our fan will not be damaged. We added a long time anti-blocking function in the design of the fan control circuit. At the same time, the wire is made of Teflon FEP high temperature resistant wire. Our design really achieves all aspects of three-dimensional waterproof, oil-proof, corrosion-proof and high temperature resistance.

Purpose: For: New Energy, Lighting, Precision Instruments, Electronic Industry, Industrial Equipment, Communication Instruments, Industrial Power Supply, Military Products

Fourth, product quality control: Our company strictly implements the ISO 9001 standard, and strictly carries out the incoming materials, production, inspection, storage and manufacturing process in accordance with the standard. All links can be traced back, problems can be found and dealt with in time, so that customers can truly rest assured and trust.

Fifth, after-sale products: all the fans we produce are made of high-quality raw materials and large-brand components, 7 days of free return if there is a problem, and the product promises quality assurance for 3 years.

Baishun Xin Fan Classification:

Axial fan

The blade of an axial fan drives air to flow in the same direction as the axis. The impeller and impeller of an axial fan

The propeller is somewhat similar. When it works, most of the airflow is parallel to the axis, in other words, along the axis. Axial fan has the lowest power consumption when the inlet air flow is 0 static pressure free air, and the power consumption will increase with the increase of the back pressure of the air flow when it is running. Axial fan is usually installed in the cabinet of electrical equipment, and sometimes integrated in the motor. Because of its compact structure, it can save a lot of space and is easy to install, so it has been widely used.

Its characteristics: high flow rate, medium wind pressure

Centrifugal fan

When the centrifugal fan is working, the blade drives the air to flow in the direction (i.e. radial) perpendicular to the axis.

The air intake is along the axis, while the air outlet is perpendicular to the axis. In most cases, the cooling effect can be achieved by using an axial-flow fan. However, sometimes centrifugal fans must be selected if the air flow needs to rotate 90 degrees to discharge or a larger pressure is required. Strictly speaking, fan also belongs to centrifugal fan.

Its characteristics: limited flow rate, high wind pressure

Mixed flow fan

Mixed flow fan is also called diagonal flow fan. At first glance, mixed flow fan and axial flow fan have nothing to do with it.

Similarly, in fact, the mixed-flow fan's intake air is along the axis, but the outlet air is along the diagonal direction of the axis and vertical axis. Because of the conical shape of the blade and cover, the fan has a higher pressure. Compared with the axial fan, the noise of the centrifugal fan is lower under the same size and other comparable performance.

Its characteristics: high current rate and relatively high wind pressure

Tubular fan

Tubular air flow can produce large area of air flow, which is usually used to cool large surfaces of equipment. This kind of wind

The inlet and outlet of the fan are perpendicular to the axis (as shown in the right picture). The tubular fan works with a relatively long barrel impeller. The diameter of the barrel fan blade is relatively large. Because of the large diameter, the lower speed can be used on the basis of guaranteeing the overall air circulation, thus reducing the noise caused by high-speed operation.

Its characteristics: low flow rate, low wind pressure

Brief Introduction to Bearing Structure of Baishun Xin Fan

The common bearings of cooling fan are ball bearing, oil bearing and magnetic bearing.

Ball bearing

Ball Bearing has changed the friction mode of bearings, using rolling friction. There are some steel balls or columns in the middle of the two iron rings and some grease lubrication. This method reduces the friction between bearing surfaces more effectively, improves the service life of fan bearings effectively, and consequently reduces the calorific value of the radiator and prolongs its service life. The disadvantage is that the process is more complex, which leads to higher cost and higher noise.

Oil bearing

Sleeve Bearing is a sleeve bearing with sliding friction. Lubricant is used as lubricant and drag reducing agent. It can be said that the most common bearing technology in the market, because of its low cost and simple manufacturing, many products including well-known brands are still in use. Its advantages are quiet in initial use, low noise and low price.

magnetic bearing

The motor of magnetic bearing is designed by magnetic system (MS), which uses magnetic force to suspend the rotor in the air so that there is no mechanical contact between the rotor and the stator. The principle is that the magnetic induction line is perpendicular to the magnetic levitation line, and the axis core is parallel to the magnetic levitation line. Therefore, the weight of the rotor is fixed on the running track, and the whole rotor is suspended on the fixed running track by using the almost unloaded axis core to support the anti-magnetic levitation line. Compared with traditional ball bearings and oil-bearing, magnetic bearings do not have mechanical contact. Rotors can run at high speed. They have the advantages of low mechanical wear, low energy consumption, low noise, long life, no lubrication and no oil pollution. They are especially suitable for high-speed, vacuum, super-clean and other special environments. Maglev is actually just an auxiliary function, and
