Shaanxi Shaanxi intelligent frequency of water supply equipment intelligent frequency of water supply equipment to find Xing rise of water, factory outlets, frequency of water supply equipment, the famous domestic brands, the national water supply service hotline 400-0030-929. Your heart is what it was like, to see what the person is! I am very happy every day, because in my world, there are no bad guys, I hope you too! Shaanxi intelligent frequency of water supply equipment condition 1, automatic secondary water supply facilities in the municipal water supply pressure should not 0.2MPa, and shall not serve more concentrated water time which may cause water pollution of water units. 2, automatic secondary water supply equipment running at the inlet pressure drop is not greater than 0.02MPa. 3, automatic secondary water supply equipment required to have anti-lost pressure, water features, and can automatically shut down in the event when the boot after recovery delay. 4, automatic secondary water supply equipment required to have automatic wake and sleep according to the set pressure value features, and can run alternately each other back. 5, automatic secondary water supply equipment imports must install backflow prevention device. Shaanxi intelligent frequency of water supply equipment vacuum to eliminate the vacuum to eliminate it is the core of this equipment, rely on it to eliminate the negative pressure in the pipe network, which does not affect the surrounding water, protect the pipe network and equipment to the municipal water supply requirements. It works relatively simple, with a composite exhaust valve is exactly the same. It mainly consists of a float to work, to move vertically up and down according to drive the float inside jars of water without the negative pressure regulating valve lift control on and off, so as to achieve the conditioning tank suction and discharge, while achieving a tank vacuum (less than when the water tank) is eliminated. Remove the vacuum is a new term, so many manufacturers make a big fuss in its body, doing a bit of mystery (packaged very well). In fact, it's just an automatic access to the air valve, and the cost is not high. Shaanxi intelligent frequency of water supply equipment to control the accuracy of the inverter built-in PID controller, real-time monitoring pressure actual value, put the number at any time and adjust the pump speed to automatically track water consumption and to maintain a constant pressure in the pipe by adjusting PI parameters, control accuracy up to 0.01Mpa. Pressure setting, easy to operate: the user can keyboard or potentiometer (option) the set pressure. It may be more than one pump cycle soft start: 1- device can be listed? Pump cycle soft-start control, which reduces the impact on the grid when the motor is started, but also reduce the impact of energy consumption and equipment wear pump start, extending the life of electrical and mechanical equipment. Timing for-pump function: In order to ensure each pump can be evenly running, corrosion does not occur, extend the life of the equipment, PLC control program can set the timer to switch the pump working hours. Can be switched between the pump cycle. Sleep function, energy efficient: in the water trough or at night when no one water pipe network pressure long-term expectations, the system will stop the pump running, once the pressure is lower than expected, the system will automatically wake up the pump in operation. Implement intelligent management of water supply systems. Multi-point monitoring system extensions: reservoir water level monitoring, fault monitoring and other machinery and equipment, once the external fault occurs, the pump or the entire system can stop working and the police. Manual / automatic function, improve the reliability of water supply equipment: When the automatic control device fails, the device can be switched to manual mode, the pump into operation, to ensure the normal continuous water supply. And then the automatic control equipment maintenance.
