I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for a negative pressure ventilation fan cooling: As the computer fever and body heat, resulting in higher than the outdoor cafes temperature 3-10 degrees or more, and the air quality poor. Negative pressure ventilation fan cooling system, is the use of large air volume of the suction fan, out of dirty, hot air inside the Internet cafes, and the formation of air convection; negative pressure principle, a steady stream of fresh outdoor air is pressed into the cafe, people like standing in the shade under a tree, like the lake, I do not feel hot. Suction fan + wet curtain cooling: the other side of the suction fan wet curtain cooling installation, water flows through the cooling surface area to expand the top-down nearly 100 times the wet curtain air through wet Lianhou, become cool and clean. You can create a more comfortable indoor environment. Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, chiller suppliers.

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, wind turbine manufacturing, its main advantage is high efficiency, low noise and air volume, but its balance demanding and prone to fluctuate after changes in working conditions. 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.

Describes the use and operation of large-scale centrifugal fan 1. Large parking areas of operational use centrifugal fan (1) fan commissioning qualified, it should be wrapped on the surface of the fan housing insulation, the use of insulating materials in order to reduce the housing external heat transmission, curtain fan, protect the bearing of safety. Moreover, the thickness of the insulation should be controlled well, but also can easily access and removal. (2) The supply situation of the bearing, vibration and bearing temperature should be checked regularly to be able to allow the normal functioning of the fan. (3) The fan just started working, vibration bearing parts is small, but with the increase in use of time, the vibration will be gradually increased. Once the maximum limit of the fan is reached, must be shut down for repairs, otherwise continue to use it, Jiujiang fans, there will be problems, danger, damage to the fan. 2. Large-scale centrifugal fan parking (1) parking fan Normal Normal parking, fire fans, which operate as follows: first off its heat source, then the fan speed to a minimum, let slow turn, until the temperature dropped to normal after cabinet then stop the main motor. (2) there is a sudden unexpected stop is the case, had unexpected stop, when the unit is in hot shutdown, the disk drive should be artificial, until the cabinet temperature dropped to normal the following so far.
