Overview

XZW eddy current non clogging self-priming sewage pump XZW eddy current non clogging self-priming sewage pump, also known as solid overflow pump or impurity pump

Product Details

XZW eddy current does not block self-priming sewage pumpAlso known as solid overflow pump or impurity pump. The impeller of this series of pumps is enclosed in a separate impeller chamber. When the impeller rotates, the liquid inside the pump generates a strong axial vortex effect, causing a vacuum at the inlet and a head at the outlet. It can transport solid materials of the same size as the pump diameter without clogging.

This series of pumps is suitable for industries such as light industry, papermaking, textile, food, petroleum, chemical, electrical, mining, municipal sewage engineering, and river pond aquaculture,

The ZW type unobstructed self-priming sewage pump is a single-stage single suction horizontal pump, with an axial suction inlet and a vertical upward discharge outlet. It rotates clockwise when viewed from the suction inlet towards the motor end.

Installation, use, and maintenance of XZW type unobstructed self-priming sewage pump

Installation of XZW type unobstructed self-priming sewage pump
The installation of XZW type unobstructed self-priming sewage pump has a significant impact on the operation and service life of the pump, so it must be carefully carried out.
1. The installation height of the suction inlet of the XZW type unobstructed self-priming sewage pump should not exceed 5 meters as much as possible. Special attention should be paid to the sealing of the suction pipeline to avoid air leakage and affect the self-priming capacity and normal operation of the pump.
2. The outlet of the XZW type unobstructed self-priming sewage pump should first be equipped with a vertical pipe (usually 0.4-1 meters) and a pressure gauge, and then the outlet flow control valve and other pipelines should be installed.
3. Reasonably configure the length and diameter of the pump inlet and outlet pipelines to reduce unnecessary head loss along the way. (Reference can be made to the straight pipe friction loss summary table for estimation)
4. When transporting over long distances, larger pipe diameters should be selected. The pump pipeline should have its own support, and the pump body itself is not allowed to bear the load of the pipeline.
5. If a check valve is installed in the discharge pipeline, it should be installed outside the outlet flow control valve.

The use of XZW type unobstructed self-priming sewage pump
1. Before use, check whether the rotation direction of the pump is correct and whether it rotates flexibly.
2. Unscrew the filling plug above the pump body, fill the reservoir, and then tighten the plug. In the future, there will be no need to refill the reservoir when starting up. The pump should not be started and operated when there is insufficient liquid storage, otherwise the pump cannot work properly and the mechanical seal may be damaged.
3. When starting up, the outlet flow control valve should be opened first to facilitate the discharge of gas during the self-priming process. After starting, adjust the opening of the outlet flow control valve to ensure that the pressure gauge reading is within the specified range (various pump type pressure control range tables), avoiding the pump from working within the lower limit of the specified range, to prevent motor overload and burnout caused by excessive shaft power or cavitation caused by excessive flow, affecting the normal operation of the pump and causing strong vibration and noise.
4. During operation, the temperature rise of the pump and motor should be checked regularly. If noise or other abnormal sounds are found, the machine should be stopped for inspection and troubleshooting before resuming operation.
5. When shutting down, the outlet flow control valve should be closed first before shutting down to avoid insufficient liquid storage in the pump due to siphon effect.
6. Regularly refuel and maintain the pump. If it is not used for a long time, the pump should be disassembled, cleaned, and oiled, and stored properly.

Precautions for using XZW type unobstructed self-priming sewage pump

The shorter the suction pipeline, the better, with a maximum length of no more than 10M
If this pump is used to pump thick and viscous slurry, the pump chamber needs to be cleaned to prevent sediment from being left inside the pump.
3. When using a self-priming pump, the pump chamber still needs to be filled with water.
After 3000 hours of regular operation, the water pump needs to be disassembled, inspected, and maintained. If necessary, vulnerable parts that are no longer suitable for use should be replaced.
5. This pump can be customized with a direct connection type, which has high concentricity, enhanced stability, and is more economical, but maintenance may be a bit troublesome.
6. Environmental temperature ≤ 45 ℃, medium temperature ≤ 60 ℃.
7. The pH value of the medium is 6-9 for cast iron pumps and 1-14 for stainless steel self-priming pumps.
8. The particle diameter is 60% of the diameter of the self-priming pump, and the fiber length is 5 times the diameter.
9. The total weight of impurities in the medium shall not exceed 15% of the total weight of the medium, and the specific gravity of the medium shall not exceed 1240 kilograms per cubic meter.
