Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic flowmeter inspection technology, and in particular relates to an inspection workbench for electromagnetic flowmeter production. Background Technology

[0002] Patent application CN202223562793.5 discloses an electromagnetic flowmeter testing bench, including an operating table. A cylinder, made of transparent material, is fixed to the upper side of the operating table via a connecting frame. A scale is provided on the surface of the cylinder. A piston is slidably mounted inside the cylinder. A reciprocating mechanism is provided on the upper side of the operating table. The reciprocating mechanism drives the piston to move back and forth within the cylinder. The interaction between the piston and the cylinder draws liquid into the cylinder and then discharges it into the electromagnetic flowmeter. The scale indicates the amount of liquid drawn into the cylinder. If the value displayed on the electromagnetic flowmeter corresponds to the amount of liquid discharged from the cylinder, it indicates that the electromagnetic flowmeter is accurate. However, the drawback of this technical solution is that it cannot verify different types of test liquids flowing through a standard electromagnetic flowmeter and the electromagnetic flowmeter being tested. The calibration of the electromagnetic flowmeter by the standard electromagnetic flowmeter cannot improve the accuracy of the test. Utility Model Content

[0003] The purpose of this utility model is to provide an inspection workbench for the production of electromagnetic flowmeters, in order to solve the technical problem that it is impossible to complete the calibration of the electromagnetic flowmeter by the standard electromagnetic flowmeter and the electromagnetic flowmeter under test when different types of test liquids flow through the standard electromagnetic flowmeter and the electromagnetic flowmeter under test, thus failing to improve the accuracy of the inspection.

[0004] To achieve the above objectives, the specific technical solution of this utility model for an inspection workbench used in the production of electromagnetic flowmeters is as follows: An inspection workbench for electromagnetic flowmeter production includes a mounting base plate, an upper support, a feed pipe, an actuator motor, a first transmission bevel gear, a second transmission bevel gear, a middle rotating shaft, an inspection liquid tank, a distributor, pipes one and two, a standard electromagnetic flowmeter, a tested electromagnetic flowmeter, pipes three and four, a liquid collector, a collection box, a middle rotating support, a partition, a positioning clip one, a positioning clip push spring one, a positioning clip two, a positioning clip push spring two, a positioning slot one, and a positioning slot two. The upper support is fixedly mounted on the mounting base plate, and the actuator motor is mounted on the upper support. The first transmission bevel gear is mounted on the output shaft of the actuator motor, and the first transmission bevel gear meshes with the second transmission bevel gear. The second transmission bevel gear is fixedly mounted on the middle rotating shaft, which is rotatably connected to the upper support. A middle rotating support is fixedly mounted on the middle rotating shaft, and multiple inspection liquid tanks are mounted on the middle rotating support. A liquid separator is fixedly installed at the lower end of the upper bracket. The liquid separator has a built-in partition for liquid separation. Pipe 1 and Pipe 2 are fixedly installed on the liquid separator. Pipe 3 and Pipe 4 are fixedly installed on the liquid receiver. A standard electromagnetic flowmeter is installed between Pipe 3 and Pipe 1. The electromagnetic flowmeter to be measured is installed between Pipe 2 and Pipe 4. A collection tank for collecting liquid is fixedly installed at the lower end of the liquid receiver. A positioning clip 1 is slidably installed on the upper end of the upper bracket. A positioning clip push spring 1 is provided between the positioning clip 1 and the upper bracket. The positioning clip 1 cooperates with the positioning slot 1. The positioning slot 1 is opened at the upper end of the middle rotating bracket, and there are multiple positioning slots 1. A positioning clip 2 is slidably installed on the lower end of the upper bracket. A positioning clip push spring 2 is provided between the positioning clip 2 and the upper bracket. The positioning clip 2 cooperates with the positioning slot 2. The positioning slot 2 is opened at the upper end of the middle rotating bracket, and there are multiple positioning slots 2.

[0005] Furthermore, a replenishment tube for replenishing test liquid is fixedly installed on the upper bracket.

[0006] Furthermore, multiple test liquid tanks are arranged in a circumferential array along the central axis of the central rotating shaft.

[0007] Furthermore, one of the plurality of test liquid tanks contains a rinsing solution, and the other plurality of test liquid tanks contain different test liquids.

[0008] Furthermore, the collection tank has a built-in weight sensor for detecting the weight of the liquid collected through the collection tank.

[0009] Furthermore, the inner walls of the test liquid tank, tube one, tube two, tube three, and tube four are all smoothed to reduce the viscosity of the test liquid.

The test liquid flows through a distributor into pipe one, passes through the standard electromagnetic flowmeter, and then through pipe three and a collector into a collection tank. A weight sensor in the collection tank automatically measures the liquid level, and a timing device records the flow time of the standard electromagnetic flowmeter to calibrate its reading. During the calibration of the standard electromagnetic flowmeter, the electromagnetic flowmeter under test is not installed between pipes two and four, and test liquid is ensured not to flow through pipes two and four. After the standard electromagnetic flowmeter calibration is complete, the electromagnetic flowmeter under test is installed on pipes two and four, and air pump A on the test liquid tank is started simultaneously. The test liquid in the test liquid tank is divided into two streams by a separator, flowing through pipe one and pipe two respectively to the standard electromagnetic flowmeter and the electromagnetic flowmeter under test. The standard electromagnetic flowmeter is used to calibrate the electromagnetic flowmeter under test, and the test liquid is collected in a collection tank. Simultaneously, to ensure the accuracy of the calibration of the electromagnetic flowmeter under test by the standard electromagnetic flowmeter, an actuator motor is activated. The actuator motor, through the meshing of transmission bevel gear one and transmission bevel gear two, causes the central rotating shaft to rotate, switching between test liquid tanks containing different types of test liquids. This completes the calibration of the electromagnetic flowmeter under test by the standard electromagnetic flowmeter, improving the accuracy of the test. Attached Figure Description

Multiple units are configured in this way. First, the standard electromagnetic flowmeter 12 is calibrated. Then, the air pump A on the test liquid tank 8 is started. The air pump A pumps out the test liquid from the test liquid tank 8. The test liquid tank 8 enters the pipe 10 through the distributor 9, flows through the standard electromagnetic flowmeter 12, and enters the collection tank 17 through the pipe 3 14 and the liquid collector 16.
