Small mortar spraying pump machine for sale

In the normal spraying, if the spray gun cannot be atomized normally, there are generally the following reasons: the mortar spraying machine low voltage will cause the spray volume to become smaller, and sometimes even the high speed gear will not start.
In this case, the cause of the low voltage should be first identified. It is extremely important to select the appropriate cross-section power cable according to the distance of the transmission line and the motor power of the spraying equipment.

The fineness of the mortar spraying machine aggregate has a certain influence on the screw mortar spraying equipment. Because there is a certain gap between the rotor and the stator of the screw spraying equipment, the small mortar spraying pump must contain a certain amount of sand with a particle size of about 1.18-2.36mm to produce the best thrust.

For example, in the sand of the mortar, when the mortar spraying machine maximum particle size is below 1.18 mm, the thrust of the screw pump is reduced, resulting in a decrease in the spray flow rate. In this case, the temperature of the mortar between the rotor and the stator generally rises.

Because some of the mortar flows under the action of the thrust, it flows toward the nozzle. However, due to the fineness of the mortar, with the increase of the pressure at the discharge end, there is a part. Instead, the small mortar spraying machine flows backwards in the direction of the hopper of the spraying equipment.

This part of the mortar is circulated between the rotor and the storage hopper. Under the action of friction, the temperature of the mortar rises, and eventually the tube can be blocked.

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 spraying machine 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.
