DK-4B Single Hydraulic Prop Seal Quality Tester

The DK-4B Single Hydraulic Prop Seal Quality Tester, produced by Taian Jiufang Mining Equipment Co., Ltd., is used in hydraulic prop repair factories (workshops) to test the sealing quality of props, quickly identify qualified props, and ensure the sealing qualification rate of props used underground. The main unit integrates a single-chip microcomputer, data acquisition, and data storage, making it easy to operate. It uses a resistance strain pressure sensor as the force measurement element, which features a simple structure, strong shock resistance, high sensitivity, good linearity, and stable performance. Main technical parameters: 1. Number of monitoring points: 1-100 points; 2. Monitoring speed: 0.3 points/second; 3. Accuracy: better than 1% FS; 4. Resolution: 0.01 MPa; 5. Operating environment: temperature 0–55°C, humidity ≤85% RH; 6. Power supply: AC 160V–240V.
