Embodiment Construction
[0022] In order for those skilled in the art to fully implement the content of the present invention, the content of the present invention will be further described below in conjunction with the drawings and specific embodiments.
[0023] Such as Figure 1 to Figure 3 As shown in the figure, a method for calibrating the pressure sensor of the main cylinder of a hydraulic vulcanizer, a calibration interface 5 is provided on the pipeline connecting the main cylinder 4 and the pressure sensor 2, and a standard pressure measuring part 6 is connected to the calibration interface 5. During the test, the pressure value measured by the standard pressure measuring piece 6 is compared with the pressure value obtained by the pressure sensor to determine whether the pressure value measured by the pressure sensor 6 is accurate. After the standard pressure measuring piece 6 is connected to the pipeline connecting the main cylinder 4 and the pressure sensor 2 through the calibration interfac...

The invention relates to a hydraulic vulcanizing machine main oil cylinder pressure sensor calibration method and a pipeline structure. A calibration connector is arranged on a pipeline for connectinga main oil cylinder and a pressure sensor, and a standard pressure measuring piece is connected to the calibration connector. During calibration, whether a pressure value measured by the pressure sensor is accurate or not is judged by comparing a pressure value measured by the standard pressure measuring piece with a pressure value acquired by the pressure sensor. During calibration, the standardpressure measuring piece is connected through a calibration structure, and the standard pressure measuring piece can be disassembled after calibration is completed, so that the main oil cylinder pipeline structure of a hydraulic vulcanizing machine returns to normal operation. The whole calibration process is convenient and fast, and the pressure sensor does not need to be disassembled.
Description
technical field [0001] The invention relates to a pipeline structure of a hydraulic system of a hydraulic vulcanizer, in particular to a calibration method for a pressure sensor of a main cylinder of a hydraulic vulcanizer and a pipeline structure. Background technique [0002] In the rubber industry, vulcanization is one of the main processes of rubber product processing. The hydraulic vulcanizer is the equipment widely used in the pressurized vulcanization method. The vulcanization pressure in the pressurized vulcanization method is one of the three elements of vulcanization, which determines the performance and quality of the product. The key factor is that the vulcanization pressure is transmitted to the mold by the main cylinder of the hydraulic vulcanizer, and then transmitted to the rubber by the mold. Therefore, the pressure of the main cylinder of the vulcanizer must be accurate. At present, most vulcanizers use pressure sensors to measure the pressure of the main c...
