The wear of the screw and rotor of the screw mortar pump, the flow rate of the mortar after the wear is significantly reduced, the spraying pressure of the mortar and the pressure of the compressed air cannot be matched, resulting in uneven spraying and eccentricity. The general solution is to replace the rotor, stator, or by adjusting the stator pressure regulator, you can adjust the bolts properly.
The movement of the gas needle in the spray 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.
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 air compressor, it is also necessary to check whether the air pipe leaks and whether the air needle is blocked.
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 wear out during use. If the wear is severe, the discharge will be uneven, and the nozzle can be replaced.
Double piston pump than screw pump use effect is good, do not need to often replace wearing parts, cost-effective, cost savings.
