High pressure centrifugal fan motor - Cause and solution can be divided into two aspects: 1 phase operation fault performance: Motor does not start, even if the cooling fan can start Yichun quality, high-speed rise is slow Yichun chillers, and with There buzzing sound; motor heating, and a burning smell. Causes and solutions are: the fuse is bad (1) power supply circuit or damage, resulting in blown fuse or fuses incorrect specifications, causing the fuse is blown, then we should replace the fuse, and Attention to appropriate. (2) The motor power supply circuit in the switch, the contact is bad, the solution is to repair and adjust it so that good contact. (3) the connection between the motor winding Weld phenomenon occurs, leading to a bad contact, then should carefully check the motor windings, welding should be firm. 2. Run overload fault performance: motor shaft power increases Yichun quality chiller, resulting in the current exceeds a predetermined value, the motor temperature anomalies. Cause and Solution: (1) If the fan a long period of high pressure, then you should be relief operations, or replace power suitable motor. (2) the fan power supply voltage is too high or too low, you will need to install a three-phase power regulator compensation cabinet. (3) bearing if badly worn, then replace the bearings and lubrication to reduce bearing wear.

Centrifugal fan performance measurement, which can be divided into the following main purpose, as follows: (1) be familiar with and know how to properly use the fan performance measuring device to measure the performance of the fan; (2) the specific methods and procedures to master the experimental ; (3) Determination of the performance of the fan, and then convert the results obtained characteristic curve, and converted into parameters. In this experiment equipment, specifically, the test device is the use of an intake test, the amount of wind turbines is the use of the inlet cone collector to be measured, which is a test test duct piping section drift, rectifier gate, etc. These are components.

Difference between centrifugal fan and blower, mainly following points, as follows: a difference: How it works is the use of curved centrifugal fan blades, then by centrifugal force gas to the cabinet office, and Roots blower, then using a 8-shaped blades, is squeezed by squeezing the gas to the outlet. Difference between the two: Site Requirements centrifugal fan is mainly used in low pressure, wind than larger establishments, and Roots blower is used in the high pressure, the wind than the smaller places. Third difference: less precision manufacturing precision manufacturing centrifugal fan, manufacturing precision Roots blower is relatively high. Four differences: parameters of centrifugal fan load demand is constant, so it is a constant fan, its air pressure change is small, and has a square torque characteristics. Roots blower fan is a constant flow, the main argument is the wind, and the wind changed very little. And high pressure air blower is conveying air volume and the number of revolutions is proportional. Five difference: noise Roots blower noise than running a large centrifugal fan.
