Abstract

The invention discloses a flexible impeller flowmeter which comprises an impeller mounting seat, an impeller, an impeller mounting shaft and a flow signal sensor. An impeller mounting cavity is formed in the impeller mounting seat, and a liquid inlet pipe and a liquid outlet pipe are oppositely arranged on the two side walls of the impeller mounting seat and communicated with the impeller mounting cavity. The axes of the liquid inlet pipe and the liquid outlet pipe coincide, and the impeller mounting shaft is sleeved with the impeller. The device further comprises a mounting cavity sealing plate, the mounting cavity sealing plate and the impeller mounting cavity are fixedly connected in a sealed mode, a mounting shaft hole is formed in the mounting cavity sealing plate, one end of the impeller mounting shaft is fixedly connected with the mounting shaft hole, and the other end of the impeller mounting shaft is located in the impeller mounting cavity. The impeller and the impeller mounting seat are eccentrically mounted; the impeller and blades on the impeller are made from rubber materials, an existing impeller flowmeter is large in machining difficulty, the precision is greatly influenced by the outside, the disclosed flexible impeller flowmeter is simple in structure, and the measurement precision can be greatly improved.

Description

Technical field [0001] The invention relates to the field of measuring instruments, in particular to a soft impeller flowmeter. Background technique [0002] Flowmeter is one of the most important instruments in industrial measurement. At present, the commonly used flowmeter on the market is used to measure the volume flow of liquid filled with closed pipes and continuous flow. However, it is not easy to measure liquids with low viscosity and corrosion resistance. With the development and progress of production, the requirements for the accuracy and range of flow measurement are getting higher and higher, and the flow measurement technology is changing with each passing day. In order to adapt to various purposes, various types of flow meters have come out; currently more than 100 flow meters have been put into use. The existing impeller flowmeter already belongs to a relatively mature technology, which mainly relates to a flowmeter used in the fields of petroleum, chemical indust...
