Operating procedures and precautions for cement pressure testing machine

Cement pressure testing machine, a fully automatic pressure testing machine integrating machine, electricity and liquid, is used for cement glue sand compressive strength tests that meet the requirements of GB/T17671-1999 and ISO0679-1998 (E). It can also be widely used in concrete, bricks and tiles and other pressure tests within the 300KN range. Below, the editor will tell you about the operating procedures and precautions of cement pressure testing machines. Let’s take a look.

1. Operating procedures of cement pressure test machine

1. Cement pressure testing machine is a high-tech integrated mechanical, electrical and liquid product. Operators must undergo prior training and master the operating instructions. Only after passing the assessment can they operate the test machine. Non-operating personnel are prohibited from turning on the power.

2. Before use, you must check the circuit and turn on the 380 V power supply, 220 V power supply, industrial control machine power supply, printer power supply, monitor power supply and computer host power supply, and enter the working state after preheating for 30 minutes.

3. Check the anti-pressure fixture and put it in the test piece, check the hydraulic loading system and enter the automatic operation state for testing. After completing the test, print the results, turn off the machine in the reverse order of starting the machine, and cover the computer, industrial control box and printer with a cloth to prevent dust and waterproof.

4. It is strictly forbidden to adjust the fine-tuning knob of the industrial control box potentiometer in working conditions. When abnormal situations are found, the power must be turned off and the power supply must be cut off immediately, and the tester must be reported to the laboratory director and repaired by the manufacturer. The machine must not be disassembled.

5. Files in the computer are prohibited from being deleted and overwritten. The disks used in this machine must not be used on other computers. Other disks are not allowed to be used on this machine to prevent computer viruses.

6. Test operators should take care of the instruments and equipment, check, scrub and maintain frequently, and regularly clean impurities in the fuel tank.

2. Things to note about cement press

1. The power supply voltage must be accurate during use;

2. The cables connected to the sensor and the host must not have intermediate connectors. If damaged, the cables must be replaced, and the wiring must be accurate;

3. When using it, you must follow the procedures specified in the instructions.

4. The motor must be turned on before the system loads. Press the "Start" key to turn on the motor and enter the test state at the same time. Press the "Stop" key in the motor running state, the machine will turn off and exit the test state.

Mechanical equipment is essentially the same. Only by mastering the correct method can the entire experimental process be smoother and the experimental data are more accurate. The above is the relevant content of the operating procedures and precautions of the cement pressure test machine, and I hope it can help everyone.
