The key to welding dust catcher

The key welding filter under the condition of welding dust catcher is set, its operation of wind velocity in the spiral passage is fixed, there will be a different work channel height, get the corresponding channel wind speed work. Welding dust catcher is different size, each kind of model and the actual use of air volume of different problems, the right wind speed is changing with the above factors, so it is difficult to give a series of appropriate wind speed to control. Above but are analyzed theoretically, there is always a corresponding to the various cases of the right wind speed in dust mortar bucket full separated, in a fixed air volume, at a fixed continuous join mortar dou inside a water supply, water level in the mortar dou will continue to improve. When the wind speed increases, and the right wind speed near the end of the water film formed gradually, but incomplete, this time in the form of water film by screw channel to the mortar bucket of water is greater than the continuous water supply, water is still rising, when it comes to water level to work right channel height is suitable forming a complete film wind speed at this point, in the form of water film row water yield equal with continuous water supply, water level remains the same. Thus dust catcher in a suitable wind speed. Under long-term operation, the balance, called automatic balance. The second, third times of water balance and so on. Water film strength is controlled by continuous water supply, water through the test to find the right pitch ratio, there will be continuous water supply of the appropriate strength water film and the ratio of pitch, with continuous join mortar, the water supply in order to achieve the full uniform water film, appropriate strength wind speed.
