How to switch frequency conversion pump?

【Asia Pump Network News】 Frequency Feed Pump is a new type of energy-saving water supply equipment. Constant pressure water supply equipment is the use of today's most advanced micro-computer control technology, the frequency converter and motor pump combination of mechatronics high-tech energy-saving water supply devices. Variable frequency feed water pump constant pressure water supply equipment to the pump outlet water pressure (or user water flow) for the set parameters through the computer automatically controls the inverter output frequency in order to adjust the pump motor speed, the user network to achieve closed-loop water pressure regulation , So that the water supply system automatically stabilizes the constant pressure at the set pressure value: water consumption increases, the frequency increases, the pump speed to speed up; water consumption decreases, the frequency decreases, the pump speed slows down. This ensures that the entire user network at any time have sufficient pressure (consistent with the user set the pressure) and water (with the user's water changes). Frequency conversion There are several ways to switch frequency: 1, variable frequency fixed operation: and a fixed frequency conversion operation, the other frequency operation, variable frequency pump as the regulation of water or pressure, first start the variable frequency pump, when the water is insufficient or the outlet pressure is less than the set value , Start the frequency reduction pump, then frequency conversion compensation adjustment. 2, frequency conversion cycle operation: that is, a frequency inverter in a certain period of time (or in accordance with the number of runs) cycle operation of the pump, each operation is the first to open the variable frequency pump, the water is not enough or the pressure is too small to start the other pump power frequency, this time Operating mode and fixed frequency similar. 3, Alternating frequency operation: that is, a frequency conversion start, insufficient water or low pressure, switch to the power frequency state, frequency change out after the start of other pumps, so that each pump is a variable frequency start effect.
