What to pay attention when using a mortar pump

2018-11-30 10:09:11

Excessive distance from the spray pipe will result in a mortar pump reduction in the amount of spray and will increase the chance of blockage. The distance of the conveying pipeline of the screw spraying equipment should be controlled according to the actual mortar condition, and the general condition should be controlled within 20 meters.
The farther the distance is, the greater the friction between the mortar and the pipe wall. As the friction increases, the amount of spray will gradually decrease. When the friction between the mortar and the pipe wall exceeds the thrust of the spraying equipment, the pipe will be blocked. phenomenon.

The movement of the gas needle in the spray mortar pump gun results in uneven discharge. Before each spraying, adjust the distance between the gas needle port and the gun nozzle. After adjusting to the best position, lock the gas needle fixing bolt and record the position of the gas needle.
During the spraying process, due to the continuous operation of the spray gun, it is easy to cause the position of the gas needle to move, resulting in uneven discharge. In this case, the position of the gas needle can be adjusted to the position of the initial recording.
Wear of the gun mouth can also cause uneven discharge. The diameter of the lance is related to the displacement of the spray equipment and the maximum particle size of the mortar. A test spray operation can be performed before use to select a nozzle of the appropriate size.

The nozzle will mortar pump wear out during use. If the wear is severe, the discharge will be uneven, and the nozzle can be replaced.
The abnormal air pressure at the discharge port is also prone to uneven discharge and poor atomization. It can check whether the air compressor is running normally and whether the pressure set by the air compressor matches the spraying equipment.
Under normal circumstances, the working pressure of the supporting air compressor of the screw spray equipment is between 0.4 and 0.6 MPa. While checking the mortar pump air compressor, it is also necessary to check whether the air pipe leaks and whether the air needle is blocked.
