Described predetermined controlling water level, refers to the consideration according to elevator design, a controlling water level of the design such as the consideration of environment for use and safe handling, and this water level as requested and elevator model size adjustment, can not affect the use of this method.
Described predetermined safety control water level, the speed that extraneous water flows into elevator pit exceedes pumping drainage speed, will continue to rise on the basis of predetermined controlling water level, elevator runs after a certain water level will affect its service life or safety, and predetermined safety control water level just refers to and on the basis of this water level, adds design capacity and the controlling water level designed.
Adopt the Method And Principle of elevator pit ponding automatic pumping of the present invention and safety control, carry out a kind of elevator pit ponding automatic pumping of designing and safety control, comprise water pump, water pump master cock, elevator controlling switch, float-type switch triggering mechanism.
Beneficial effect of the present invention is:
A kind of device for detecting water level of elevator bottom pit of the present invention and check processing method thereof, effectively can lower damage and the corrosion of lift facility, reduce the personal injury to passenger.Existing elevator pit is mostly low than building bottom, often pit ponding occurs, and causes elevator device failure or corrosion, electric elements lost efficacy, even can cause passenger's personal injury etc. time serious.Apparatus of the present invention can when elevator pit ponding Auto-drainage and emergent stopping elevator.
