What is the relationship between the width and diameter of impeller blade and shot blasting machine, projectile ejection velocity under certain conditions, such as 75 meters per second, the main premise is to know the size of the known shot blasting machine can roughly calculate the amount of the shot blasting machine, if you want to calculate
1. The number of shot blasting machine can be press type calculationThe total quantity of n- shot blasting machine;The number of rows of n1-- chamber nine is up, when the chamber length is determined, N1 can be determined;N-- the number of shot blasting machines on each row; the number of N2 on each row of shot blasting machines can be determined by drawing method. According to the shape, each shot blasting machine workpiece turning and most saved blow angle angle, draw the fan-shaped pill blasting machine each flow area location map. The method is first to draw a concentric circle A. according to the angle of the extraction, and then to draw the tangent line of the two A circles, so that the included angle is a fan angle 0. These two tangents are the two sides of the sector of the shot blasting fan. As shown in figure 21.1169, and the transfer of blasting area adjacent to the fan jet has a certain degree of overlap, so he set off the blast wheel size H1, H2, H3 and H4, as shown in figure 21.70a, in addition, under the blasting should be staggered with each other about 250nun distance in the horizontal direction. Or according to the blasting machine shaft honing B draw horizontal diffusion pill material scattering range, so that the adjacent blasting each pill flow do not interfere with each other in the vertical plane, as shown in figure 21.1-7ab.
If there is any problem, you can Baidu Chengdu Delong shot blasting machine, Mr. DingIf you think it makes sense, thank you for the score! 3QThe following is online copy, I said I do not understand, or look at the actual situation, listen to manufacturers build meaning!
I think so. The size and shape of the impeller and blade of the shot blasting machine is designed by the manufacturer, which is considered good or durable by the manufacturer. For example, you shot blasting machine motor is 11KW motor, that shot blasting volume is 250kg/min, ammeter readings of about 20 (about). In general, regardless of the size and shape of your impeller and blade, manufacturers will ensure that this basic quantity! A large amount of burning motor, small amount of shot blasting, the effect is not good! If your shot blasting volume should be large, then the motor should also be larger, and the impeller and blade will naturally be larger! I think the size of shot blasting is related to the model (size) of shot blasting machine.
2. Calculation of shot blasting and shot blasting volumeEach shot blasting machine shall have an average shot shot amount calculated by pressingGw-- average shot shot (kp/min) of each shot blasting machine;GM*G1-- cleans the total amount of pellets (kg/h);N-- number of shot blasting machines.The shot blasting machine can be selected according to the average shot blasting quantity which should be thrown by the nine throwing machine. But for multi shot blasting equipment, each shot blasting machine shot blasting volume is not necessarily average throw nine quantity, GA according to each shot blasting machine in the room position, choose the appropriate throw nine quantity. Some key parts of the box difficult to clean the position of the shot blasting machine should use larger shot blasting, but all shot blasting machine blasting amount sum equal to the total pill amount Gn
