The air pressure drainage device is to use the negative pressure principle to pump the water in the water sump to dry, and then discharge the absorbed waste water to the drainage ditch or nearby base well through the positive air pressure difference;
It is mainly composed of water collecting tank, filter type water absorption probe, electrical control and relevant pipelines.
Product features:
1. Simple installation: without adding sump, the liquid level sensor can be placed at the lowest part of open ditch in each drainage section to realize suction.
2. Standby mechanism: double liquid level sensor, start and stop will not fail.
3. Strong controllability: there is no need for personnel on duty, and the self-contained remote control program can monitor the suction point of each equipment remotely from time to time.
4. High efficiency: low liquid level control can drain the water inside the foundation pit without any residue;
5. Good effect: the lowest liquid level is only 5cm.
