The long-term success of the continuous negative pressure automatic slag discharge and water drainer relies on quality. The longevity of a brand is not built on exaggerated marketing but on integrity. The effectiveness of a product does not depend on low prices but on quality, and your quality is ultimately determined by your vision.

The PZ-L continuous negative pressure automatic slag discharge and water drainer adopts a dual-tank structure. By utilizing the height difference of the water inlet valve and the secondary adjustment of the water distribution system, it achieves continuous water storage and drainage functions. This effectively resolves the issue of water accumulation and blockage in gas extraction pipelines caused by intermittent drainage.

Product Usage Precautions

1. Avoid collisions during transportation; handle with care.

2. After installation, ensure the drain valve is not submerged by water in the roadway, as this will prevent drainage.

3. Keep the area around the drainer clean to avoid blockage of the drain valve by rock (coal) dust (mud).

4. The central axis of the drainer should be as perpendicular to the horizontal plane as possible to reduce frictional resistance during the float's ascent.

5. Regularly inspect the working condition of the drainer and address any issues promptly.
