Induced draft fan vibration increases reasons, according to the analysis professionals in general are mainly the following for: Material (1) Fan rotating parts used uneven Nanchang fans offer, or a manufacturing process an error has occurred, so that rotor mass imbalance. (2) The fan installation, maintenance quality, but off. (3) rotor wear and tear, or rotor damaged, or is the front and rear guide vanes for wear, deformation. (4) The opening of the import and export flap adjustment is not in place, or the bearings and bearing, etc. is faulty. (5) access technology, however, or under high load condition, vibration increases. In addition to these reasons, in addition there is the high-load or full load, vibration or instability, which appeared in periodic vibration. For these reasons, the measures we can take are: first, the disintegration of Nanchang fans for fans, and then on the parts checked for damage, if damaged the need for replacement. Connection bolts and anchor bolts accordingly check if loose should be tightened.

A brief description of the difference between the forward and backward analysis of forward centrifugal fan centrifugal fan, the material is the use of high-quality steel plate, then crimping process. Its main advantage is low speed, you can use a smaller or thinner bearings, and the operating range is wide, and low cost. However, it also has shortcomings, mainly structural strength of the blade is relatively low, and therefore can not run at a high speed. Backward centrifugal fan, it is by casting, mainly used for air ventilation, dust and smoke, and its main advantage is the high efficiency, low noise and air volume, but its balance demanding, but there Changes in operating conditions likely to cause volatility. Next, we have to analyze where the difference between them. One difference: power to overcome the system resistance static head, centrifugal fans to pour forward after less than centrifugal fan. Since the fan blades in the backward channel is gradually expanding, so the hydraulic loss is less than the front-loaded, so that after the forward centrifugal fan centrifugal fan less efficient than dumping. Difference between the two: power consumption due to the centrifugal fan after the forward tilt less efficient than centrifugal fan, so after dumping its power consumption is greater than the centrifugal fan. Third difference: noise forward centrifugal fan operating noise centrifugal fans to pour over the latter.

I believe Jinxiang Yun plant cooling ventilation plant must be your best choice for cooling ventilation equipment Determine the pipe diameter wet curtain water circulation system used to determine the wet curtain into the pipe diameter and the pipe diameter according to the pump diameter, flow, velocity, etc. . Be sure to calculate the water enough to use, or in the future there will not wet wet curtain of water. 4, the quality of the pump, try to choose good quality water pumps, good quality pump will reduce maintenance costs and trouble, suggest that you choose designer pumps. 5, in the wet curtain construction installation details can not be ignored, pump installation should pay attention to seal pipe joints, especially the water pump does not leak and plug, it is best to install filter valves, pressure reducing valve and check valve, can be reduced Pump unnecessary problems arise during use.
