Constant-pressure water supply controlling method without pressure sensor
The invention discloses a constant-pressure water supply controlling method without a pressure sensor. In the traditional constant-pressure water supply controlling scheme, the purchasing cost of a pressure sensor takes up to 20%-50% of a whole constant-pressure water supply controlling system, so the cost is high, and the sensor is easily interfered during working process. The controlling method comprises two steps of calibrating the constant-pressure data of a water pump, and controlling the constant-pressure water supply of the water pump. In the technical scheme, based on the centrifugal water pump model, data of pressure, flow, rotating rate and power of the water pump are pre-calibrated on the water pump testing system and treated through a constant-pressure water supply algorithm without the pressure sensor, so that the function of maintaining the constant pressure of the outlet of the water pump is realized in a condition without the pressure sensor, problems caused by the usage of the pressure sensor are avoided, the purchasing cast and the maintenance cost of the system are reduced, and the reliability of the system is improved.
