Electrical casing pressure tester structure:
The testing machine is composed of a base, a hydraulic mechanism, a lifting platform, and a dial gauge deformation measuring device. This design ensures stability, accuracy, and ease of use during the testing process.

This equipment complies with JG/T3050 "Insulation Electrical Bushings and Fittings for Construction," GB/T14823.2 "Special Requirements for Electrical Installation Pipes - Rigid Insulation Material Flat Pipes," and ZBG33008 "Polyethylene Plastic Corrugated Wire Pipes." Compared to other tensile testing machines, this model offers consistent pressure application, accurate outer diameter measurement, user-friendly operation, and reliable results. As a result, it's widely used in various industrial applications.

Installation and Use:
1. Loosen the straps, clean the surface of the test machine, and re-lubricate the moving parts with thin oil.
2. Adjust the base so that it is level and stable.
3. Place the test specimen in the center of the lifting platform. Manually press the jack (make sure the bleed valve is closed first) to bring the specimen into contact with the square iron block. At this point, do not apply pressure yet. Then, adjust the dial indicator and set its pointer to zero.
4. Turn on the display power and reset the value to zero.
5. Choose the appropriate pressure value based on the type of conduit being tested.
6. Measure the initial outer diameter D1 of the sample. Place the sample on the lifting plate, tighten the return valve stem, and pull the handle to lift the platform. The sample will come into contact with the indenter (square iron block). Before the top of the indenter touches the specimen, adjust the dial indicator to the working platform. After tightening the screw, use the fine adjustment knob to bring the probe into contact until the dial reads “0.â€
7. Continue raising the platform until the top of the indenter makes contact with the specimen and then apply the required force within 30 seconds.
8. Record the dial gauge reading after one minute. This reading represents the difference between the original outer diameter D1 and the flattened outer diameter D2. The difference should not exceed 25% of D1.
9. Loosen the fastening screw, allow the adjustment rod to drop, and release the return valve stem to let the platform slowly descend. Due to the damping effect of the hydraulic system, you may need to press the platform down manually to reach the lowest position.
10. After another minute, use a vernier caliper or similar measuring tool to measure the outer diameter D3 of the flattened sample. The difference between D3 and D1 should not be more than 10% of D1.
11. Finally, inspect the surface of the sample for any cracks or damage.
This comprehensive procedure ensures accurate and reliable testing of electrical conduits, making it an essential tool for quality control in construction and manufacturing industries.
