Filter installation andChongqing FanInstallation requirements-For the question of whether the fan is equipped with a filter, it is recommended that the customer match, but its role should not be underestimated. Why do you say that? Because the internal clearance of Chongqing fan is very small. If you don't pay attention and just suck in a hard thing, it will cause more or less damage to the blower. However, if a filter is installed, the result will be different. It will be filtered directly here and will not have any impact on the fan. Clean the filter regularly.

Chongqing fan: can be installed at the air inlet and connected with galvanized pipe fittings. However, it should be noted that the diameter of the filter can only be larger than the diameter of the fan, but not smaller than the diameter of the fan. Otherwise, it will affect the air intake of the fan and the operation of the fan. If the fan is installed outdoors, it is even more necessary to install a filter. The other port can face down to prevent raindrops from being sucked into the fan when it rains. PurchaseChongqing FanAt the same time, we should know a lot about the brand, specification, use, maintenance and power of the product.

1) Chongqing fan: If the impeller diameter of the selected fan is much larger than that of the original high-pressure fan, in order to use the original motor shaft, bearing and bracket, it is necessary to calculate the start-up time of the motor, the strength of the original parts of the high-pressure fan and the critical speed of the shaft.

2) The selected new high-pressure fan should fully consider the use of the original equipment, suitable for on-site production, installation and safe operation.

3) According to the different physical and chemical properties of the high-pressure fan conveying gas, select high-pressure fans for different purposes. Explosion-proof high-pressure fan shall be selected for conveying explosive and combustible gas; dust or pulverized coal high-pressure fan shall be selected for conveying dust or pulverized coal; anticorrosion high-pressure fan shall be selected for conveying corrosive gas; high-temperature high-pressure fan shall be selected for working in high-temperature occasions or conveying high-temperature gas.

4) WhenChongqing FanWhen selecting a high-pressure fan with more than two types on the performance table, a high-pressure fan with higher efficiency, smaller number of machines, and larger adjustment range should be selected. Of course, comparisons and decisions should also be made by weighing the pros and cons.

5) When a centrifugal high-pressure fan is selected, when the motor power is less than or equal to 75kW, a valve that is only used for starting cannot be installed. When the centrifugal boiler induced draft fan is selected to discharge high-temperature flue gas or air, a starting valve should be set to prevent overload during cold operation.

6) Chongqing Fan: Before choosing a high-pressure fan, it is necessary to understand the production and product quality of high-pressure fans, such as the varieties and specifications of high-pressure fans, the special uses of various products, the development and promotion of new products, etc., and should also fully consider environmental protection Requirements, so as to select and optimize fans.

7) For the ventilation system with noise reduction requirements, high-pressure fans with high efficiency and low impeller circumferential speed should be preferred, and work at the speed point; according to the transmission mode of noise and vibration generated by the ventilation system, corresponding noise reduction and vibration reduction measures should be taken. The vibration reduction measures of high-pressure fans and motors can generally be based on shock absorption, such as spring shock absorbers or rubber shock absorbers.

8) Chongqing fan: When selecting high-pressure fans, try to avoid parallel or series operation of high-pressure fans. When unavoidable, high-pressure fans of the same model and energy should be selected to work together. When the series connection is adopted, there should be a certain pipeline connection between the high-pressure fan and the secondary high-pressure fan.

The above is how to choose the introduction of Chongqing fan.
