AI Technical Summary
The existing MVR system has a large range of inlet pressure for the volute, and the amplitude varies, which causes the drainage device of the volute to drain in different ways under negative and positive pressure, affecting system performance and equipment life.
The system employs an automatic adjustable volute drainage system adaptable to both positive and negative pressure. It includes a volute, a pressure transmitter, a control system, a volute drainage tank, a level gauge, a three-way valve, a negative pressure pump, a solenoid valve, and a check valve. The control system automatically adjusts the drainage method according to the pressure conditions to achieve drainage of accumulated water under both positive and negative pressure.
It improves the intelligence and efficiency of volute drainage, extends the service life of the MVR system, reduces manual operation steps, and improves equipment operating efficiency.
