The invention relates to a frequency-conversion steady-flow control system and a control method thereof which belong to the field of liquid (including water meters and oil meters) flow detection equipment. The control system has the design point that a frequency conversion water pump consists of a water pump, a frequency converter and a control box; a steady flow tank body consists of a tank body which is provided with a water inlet and a water outlet; the inside of the tank body is provided with rectification boards and partition boards; the rectification boards and the water inlet are arranged on the same side; the rectification boards are orderly provided with a first rectification board, a second rectification board and a third rectification board from bottom to top, wherein the first rectification board is provided with a large water through hole; the second rectification board is provided a medium water through hole; and the third rectification board is provided with a small water through hole; one end of each of the first, second and third rectification boards is connected with the inner wall of the tank body, while the other end is connected with the partition boards; the inside of the tank body is provided with a first partition board and a second partition board; the second partition board is arranged on the top in the tank body; and the water outlet of the tank body is connected with a standard water flow device. The frequency-conversion steady-flow control system has simple structure and practical method, further improves the steady flow of liquid, and is especially suitable for matching flow detection equipment of the water meter and the oil meter.
Description
technical field [0001] The invention relates to the field of liquid (water meter, oil meter) flow detection equipment, and relates to a frequency conversion steady flow control system and a control method thereof. Background technique [0002] The steady flow device mainly plays the role of stabilizing the water flow, so that the stabilized water flow can be provided to the external water equipment for use. For example, the steady flow device can be connected to the external flow standard device to detect the water flow. Most of the current water flow detection devices can only The stable water flow is detected, so the flow stabilization device is essential and plays an important role in practical applications. [0003] Such as the authorized announcement number CN2789322Y published in the Chinese patent literature, the authorized announcement date was June 21, 2006, and the name is "tap water supplementary pressure water supply steady flow tank", which is used for a kind of...
