Pointer type flow setting device of liquid pump

Abstract

The invention discloses a pointer type flow setting device of a liquid pump and relates to a flow setting device of a liquid pump. The pointer type flow setting device is provided with a flowmeter and a flow setting gauge, wherein the flow setting gauge is provided with a flow pointer and a setting pointer, a dial plate is provided with flow scales, and an electromagnetic rotor is arranged in the flow setting gauge; the flowmeter inputs flow pulse signals to a signal processing circuit, and the flow pulse signals are amplified and divided by the signal processing circuit and then are input to a driving circuit; and the driving circuit is connected with the electromagnetic rotor, the electromagnetic rotor is connected with the flow pointer by a gear, the pointer is provided with a signal output device, the signal output device is connected with a liquid pump control device, and the liquid pump control device can control the liquid pump to stop running. The flow of a liquid pump can be set by simply shifting the setting pointer, thereby achieving the purposes of visual setting and simple setting operation. Besides, the unrestrained pointer type flow setting device of a liquid pump can be used without operational knowledge and is suitable for setting the flow of a liquid pump.

Description

technical field [0001] The invention relates to a flow setting device of a liquid pump, in particular to a pointer type liquid pump flow setting device. Background technique [0002] As we know, the existing flow setting device is provided with a flow meter, the flow meter is connected to the CPU processor, the CPU processor is connected with a liquid crystal display and a keyboard, and the parameter setting flow on the liquid crystal display is adjusted by the keyboard, and the CPU processor The liquid pump is controlled according to the set parameter flow rate and the flow signal of the flow meter. This uses a flow setting device. Since the flowmeter is connected to the CPU processor, and the CPU processor is connected to a liquid crystal display and a keyboard, the parameters on the liquid crystal display are adjusted through the keyboard to set the flow rate. The setting is not intuitive, and the setting operation is cumbersome and requires Certain operating knowledge, ...
