Description

Technical Field

[0001] The invention relates to the technical field of oil cylinder detection, and in particular to a pressure detection device and a detection method for a main oil cylinder of an industrial pump. Background Art

[0002] The oil cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the reduction device can be eliminated, and there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various industrial machinery. Since the sealing and pressure resistance of the oil cylinder are crucial to the performance of the oil cylinder, pressure testing is usually required after production to prevent unqualified products from entering the market and affecting the product reputation;

[0003] According to a Chinese patent with the authorization announcement number CN118913934B, a strength detection device and method for hydraulic cylinder production are disclosed. After the output end of the cylinder body is moved outward, the extrusion plate is pushed downward. On the one hand, the downward movement of the extrusion plate can detect the quality of the cylinder body. On the other hand, the extrusion plate generates pressure on the water, so that the water generates uniform water pressure on the surface of the cylinder body, thereby performing strength detection on the cylinder body. However, in fact, the main factors affecting the performance of the cylinder are the sealing and pressure resistance inside the cylinder. Therefore, the detection of the pressure resistance outside the cylinder cannot accurately reflect the pressure resistance level inside the cylinder and the pressure resistance level between the piston ring and the cylinder wall during actual use of the cylinder. For this reason, we propose a pressure detection device and detection method for the main cylinder of an industrial pump to solve the above technical problems. Summary of the invention

After injecting an appropriate amount of hydraulic oil into the cylinder of the main oil cylinder of the industrial pump through the oil pump, close the check valve of the oil pump to ensure that the hydraulic oil injected into the cylinder of the main oil cylinder of the industrial pump cannot flow back;

[0055] S3.

[0060] 1.

The detection is more accurate and has high stability. The positioning rod and the main oil cylinder of the industrial pump can be positioned by simply inserting the lock column into the lock groove. The operation is simple, and the detection efficiency of the main oil cylinder of the industrial pump is greatly improved.

[0061] 2. In the present invention, the driving part drives the positioning part and the main cylinder of the industrial pump to rotate slowly, and the detection hydraulic oil located inside the main cylinder of the industrial pump is discharged through the oil inlet of the cylinder to avoid waste of hydraulic oil. The oil is collected through the collecting oil tank at the bottom and then returned to the inside of the oil tank for collection to facilitate the next detection needs.

[0062] 3. In the present invention, the rotation of the driving shaft of the driving part also drives the telescopic tube, the telescopic tube, the telescopic rod and the ball head to rotate together. Further, under the sliding connection between the ball head and the ball groove, the left and right ends of the fixed platform are turned up and down along the hinge position of the hinge part, so that the main oil cylinder of the industrial pump continuously swings up and down during the rotation process, thereby accelerating the oil discharge efficiency of the main oil cylinder of the industrial pump.
