Embodiment Construction

[0020] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0021] Such as figure 1 As shown, a liquid flowmeter automatic cleaning device includes a cleaning agent container 5 and a bidirectional centrifugal pump. Two inlets are respectively set up on both sides of the cleaning agent container 5, which are respectively the first inlet and the second inlet. The cleaning agent There are two outlets on both sides of the container 5, which are respectively the first outlet and the second outlet. Both ends of the two-way centrifugal pump are respectively connected to the first inlet and the first outlet of the cleaning agent container through pipelines to form a positive cleaning circuit. Both ends of the bidirectional centrifugal pump are respectively connected to the second inl...

Abstract

The invention provides an automatic cleaning device for a liquid flowmeter. The automatic cleaning device comprises a detergent container and a two-way centrifugal pump, wherein a first inlet and a second inlet are formed in two sides of the detergent container respectively, a first outlet and a second outlet are formed in the two sides of the detergent container respectively, and the two ends of the two-way centrifugal pump are connected with the inlets and the outlets; a liquid level meter is also mounted on the detergent container, valves are mounted at the inlets and the outlets, and the liquid level meter, the valves and the two-way centrifugal pump are all connected to a computer control device through circuits; a rotatable flowmeter connecting plate connected with the flowmeter is arranged on a cleaning loop between the detergent container and the two-way centrifugal pump. According to the automatic cleaning device, the scrapping of the liquid flowmeter due to metering function failure after blockage can be effectively avoided and the high-precision metering function of the liquid flowmeter can be recovered within a relatively short time.

Description

technical field [0001] The invention relates to a cleaning device, in particular to an automatic cleaning device for a liquid flow meter. Background technique [0002] When Coriolis mass flowmeters, positive displacement flowmeters, and velocity flowmeters are used in liquid metering occasions such as oilfield squadrons and mine metering, due to the influence of the physical properties of the medium and external factors, the flowmeter will lose Its measuring parts (or measuring tubes) have accumulated dirt. Based on the measurement principle of the flowmeter and the field test analysis, the dirt seriously affects the scientificity and accuracy of the liquid flow measurement; moreover, when the periodic verification is carried out for the flow meter with dirt, it must be descaled before the verification work can be carried out , so as not to affect the accuracy of the test results and the impact of dirt on the standard device. Therefore, starting from the science, accuracy ...
