Direct-selling crane accessories double-blade radiator, with many discounts. The manufacturer uses a unique double-blade fan to compare with traditional fans. It has a unique style and high efficiency is the focus of users.
Zhongrui Machinery produces small cranes, small crane accessories, floor forming machines, trenching machines and other products
Radiators mainly rely on convection. If the convection is destroyed, the thermal efficiency will be greatly reduced.
Oil-containing bearings are sleeve bearings that use sliding friction. They use lubricating oil as a lubricant and drag reducer. They have low operating noise and low manufacturing costs during initial use. However, this kind of bearing wears seriously and has a longer life than ball bearings. There is a big gap. Moreover, when this kind of bearing is used for a long time, due to the oil seal (computer radiator products cannot use high-end oil seals, generally ordinary paper oil seals), the lubricating oil will gradually evaporate, and dust will also enter the bearing, causing the fan to Problems such as slower speed, increased noise, and in severe cases, severe vibrations caused by eccentricity of the fan due to bearing wear.
. The radiator is not immune to dust. Due to the wind flow, the wind pressure generated by the radiator fins does not press down vertically, but spreads in an annular shape. This is like a ceiling fan on the roof of your home. The air flow directly below the fan It is often not as strong as the outside of the ceiling fan, and the dust in the air will circulate around the outside with the wind speed and adhere to the heat dissipation fins around the fan, causing air flow to be blocked. At the same time, the return air caused by the blockage of the fins will be drawn in. A large amount of dust enters the fan blades, reducing the service life of the radiator; water vapor in the air adheres to the fan blades, causing dust to adhere to the fan blades, increasing the weight of the blades and reducing the speed [small crane]; the radiator bearing rotates at high speed, and with use Over time, oily material spills out of the bearings, sticks to the radiator, and accumulates more dust.
The speed of the radiator fan is determined by the number of turns of the coil in the motor, the operating voltage, the number of fan leaves, inclination angle, height, diameter and bearing system. When the fan structure is fixed, the rotation speed of the DC fan (that is, the fan using DC power) changes synchronously with the change of the operating voltage. The fan's speed can be measured through the internal speed signal, or it can be measured externally. The external measurement uses other instruments to see how fast the fan rotates. The internal measurement can be viewed directly in B or through software. The internal measurement error is relatively large.
