What are the precautions for an automatic butter pump?

Precautions for automatic butter pump:

1. When connecting the power, check the integrity of the equipment first.

. Preheat the equipment;

2、 Before the whole machine starts working, check whether the motor rotation is correct (facing the triangular pulley, it should rotate clockwise);

3、 Push the copper cap on one side of the counter on the flowmeter inward, (referring to the 1st stage) 2nd stage flowmeter. After each indication is complete, rotate the handwheel counterclockwise and set the size pointer back to zero. The pointer of the counting disk will automatically return to zero. If continuous counting is required, the copper cap will no longer be pressed;

4、 Controlling the tightness of the gripper plate of the oil gun can roughly adjust the oil output;

5、 Ordinary cables shall not be used to replace the dedicated rubber sheathed cables of this machine, nor shall they be disassembled or connected arbitrarily;

6、 The inlet and outlet pipes, oil guns, and cables should be wound around the designated positions when not in use, and should not be dragged anywhere. Before inserting the pipes into the oil tank (or oil drum), they should be cleaned and tidy;

7、 After using the finished product, it is necessary to clean the inlet and outlet pipes as well as the oil outlet hose.

2. Methods of using the V-method and Z-method of ultrasonic flow meters

The V-method and Z-method of ultrasonic flow meters are two mainstream installation methods, and the choice depends on the size of the pipe diameter and the characteristics of the medium. Correct installation is the key to ensuring measurement accura

cy.

. The V-method installation is suitable for scenarios where the pipe diameter is small (usually less than 300mm) and the medium has less attenuation of ultrasonic waves. Two probes are installed on the same side of the pipeline, arranged in a V-shape. 1.1 Choose the installation point to find a straight section of the pipeline that is uniform, without welds or throttling devices. Ensure that the length of the upstream straight pipe section is not less than 10 times the pipe diameter, and the downstream section is not less than 5 times the pipe diameter. 1.2 Use tools such as sandpaper or file to thoroughly clean the surface of the pipeline at the installation site, remove rust and oil stains, and make it smooth and flat. 1.3 Determine the position of the probes on one side of the pipeline. Determine the installation points of the two probes so that they are staggered along the circumference of the pipeline, forming a V-shape. The angle between the centerline of the probe and the axis of the pipeline is usually 45 degrees. Accurately mark the position on the pipeline based on the probe spacing calculated by the instrument. 1.4 Apply coupling agent evenly on the emission surface of the probe and the marked installation location of the pipeline, using a sufficient amount of coupling agent (such as Vaseline, butter) to eliminate air and ensure effective transmission of ultrasonic waves. 1.5 Installation and fixation of probe: Place the probe accurately at the marked position and fix it using specialized fixtures or other methods to ensure that the probe is in close contact with the surface of the pipeline. 1.6 Connect the cable of the probe to the flowmeter host, paying attention to the correspondence of positive and
