Uses of pneumatic pressure switches include: Switch a household well water pump automatically when water is drawn from the pressure tank. Switching off an electrically driven gas compressor when a set pressure is achieved in the reservoir; Switching off a gas compressor, whenever there is no feed in the suction stage. in-cell charge control in ...
A simple control system for a water well. Referring to the figure on the left, a submersible water pump is installed in a well. The pressure switch turns the water pump on when it senses a pressure that is less than P lo and turns it off when it senses a pressure greater than P hi. While the pump is on, the pressure tank fills up.
There are three different methods for detection of water shortage: Pressure switch on suction manifold or float switch/electrode relay in the supply tank: Dry-running protection with pressure/level switch. Measurement of inlet pressure in the suction manifold by means of an analogue pressure transmitter: Dry-running protection with pressure ...
For example, a water pump can be controlled by a pressure switch so that it starts when water is released from the system, reducing the pressure in a reservoir. Pressure range, sensitivity, dynamic response and cost all vary by several orders of magnitude from one instrument design to the next.
The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination ...
