Description
[技术领域][technical field]

[背景技术][Background technique]
由于恒压设备需配蓄水池，无法避免水质的二次污染，但其优点是有一定蓄水能力，即使自来水停水也可继续供水直到蓄水用完。常规恒压设备的控制系统均需配置一台变频器、一个供水控制器或PLC、一个压力传感器。根据目前的使用情况，主要存在以下不足之处：当使用过程中变频器发生故障或损坏时，设备将无法正常启动或恒压；当控制器发生故障后，系统也将直接停机，无法供水；而当压力传感器损坏时，设备则会发生失控的危险，甚至可能会造成压力过高，损坏管路或其他配件。Since the constant pressure equipment needs to be equipped with a water storage tank, secondary pollution of water quality cannot be avoided, but its advantage is that it has a certain water storage capacity, and even if the tap water is cut off, it can continue to supply water until the water storage is used up. The control system of conventional constant pressure equipment needs to be equipped with a frequency converter, a water supply controller or PLC, and a pressure sensor. According to the current use situation, there are mainly the following shortcomings: when the frequency converter fails or is damaged during use, the equipment will not start normally or maintain constant voltage; when the controller fails, the system will also stop directly and cannot supply water; When the pressure sensor is damaged, the equipment will be in danger of being out of control, and may even cause excessive pressure and damage pipelines or other accessories.

本实用新型的工作原理为：当自来水进入蓄水池，待蓄水池水位高于低水位传感器时，满足启动条件，变频器控制器通过传感器检测用户管网中的实际压力，实际压力和用户所需的设定压力比较；如在用水高峰时，实际压力小于设定压力，变频控制器发出启动命令，自动启水泵一，自动控制水泵一转速直到达到50Hz，如压力仍达不到设定压力，变频控制器延时启动水泵二，当实际压力逐步达到设定压力时，两台变频控制器自动进入效率平均分摊模式，同时变频达到节能的目的；当用水高峰过后，运行频率慢慢降低，最后变频控制器发出减泵信号，自动减掉先启动的水泵一；当其中一个压力传感器故障或损坏，变频控制器自动切换备用压力传感器，若因自来水停水造成蓄水池液位降低，低水位传感器则给出停机信号，以保护水泵机组。The working principle of the utility model is: when the tap water enters the reservoir, when the water level of the reservoir is higher than the low water level sensor, the start-up condition is met, the inverter controller detects the actual pressure in the user pipe network through the sensor, the actual pressure and the user The required set pressure is compared; if the actual pressure is lower than the set pressure at the peak of water consumption, the frequency conversion controller will issue a start command to automatically start the water pump 1 and automatically control the speed of the water pump 1 until it reaches 50Hz. If the pressure still does not reach the set pressure When the actual pressure gradually reaches the set pressure, the two frequency conversion controllers automatically enter the efficiency average sharing mode, and the frequency conversion achieves the purpose of energy saving at the same time; when the peak water consumption is over, the operating frequency is gradually reduced , and finally the frequency conversion controller sends out a signal to reduce the pump, automatically reducing the first pump one; when one of the pressure sensors fails or is damaged, the frequency conversion controller automatically switches to the backup pressure sensor. The low water level sensor then gives a shutdown signal to protect the water pump unit.
