With the rapid development of electronic technology and information technology, pressure measurement and automatic control technology has deep into the people live and work in various fields, as one of the power control mode of pressure switch is not only confined to the onoff the two state control of the pressure at a point, but on the basis of the switch control to also can achieve resolution size, pressure, sequential control point set Long-distance signal transmission and other functions, so electronic pressure switch instead of all kinds of mechanical pressure switch has gradually become the mainstream of application. And now the pump industry pressure controller has achieved humanized automatic control, but also to achieve the objective requirements of water and electricity saving.
Pump pressure controller, also known as pump automatic controller. When the pressure in the system is higher or lower than the safety pressure, the pressure sensor in the controller immediately moves to make the contact in the controller connected or disconnected, and the equipment stops working at this time; When the pressure in the system returns to the safe pressure range of the equipment, the pressure sensor in the controller immediately resets, so that the contact in the controller is connected or disconnected, and the equipment works normally at this time. It can start and stop the pump according to the detected water source state, pipeline water consumption and pipeline pressure changes and other data, can completely replace the traditional system composed of pressure tank, pressure switch, water protection device, check valve four. As long as the controller directly to access without external line, relay, and realize the low pressure water pump pumping, enough pressure to stop pumping, to save energy and prolong the life of the pump, and realize the water pump unattended operation, widely used in pumps, self-priming pumps and without tower automatic water supply device, applicable to the family, the unit for, irrigation and drainage system, can realize the courtyard garden shed planted plant automation.
Usually there are pressure switch pumps, are some high pressure pumps, such as water pumps to tall buildings, in order to reach a certain pressure, the pump shut down, to avoid no load but the pump has been in the turn, waste electricity, at the same time the role of the energy storage tank will not let the pressure immediately lost, so do not need a lot of water pump will not start. When the tap water pipe or pump pressure less than the lower limit of the switch pressure adjustment, automatic switch on, began to pump running, when the water pipe or pump pressure is greater than the switch pressure adjustable highs, switch automatically disconnect, pump stop, pressure of upper and lower switch with water level and pump pressure for different adjustment range.
