Do you know how to operate a cement pressure test machine? What are its characteristics?

Cement pressure testing machine is also called cement constant stress testing machine for compressive strength or flexural resistance test of ordinary cement cement or oil well cement. It not only complies with the compression and flexural test of cement sand strength of GB/T17671-1999 standards, but also complies with the requirements of GB/T16491-2008, GB10238-2005, JJG139-1999, GB/T17671-1999 and other standards. So do you know how to operate the cement pressure test machine? What are its characteristics? Let’s learn about it with the editor.

1. Test operation steps of cement pressure testing machine

⑴ Select the range of measurement according to the test piece, and align the tile lines.

⑵ Adjust the buffer valve to adapt to the range range.

⑶ Rotate the main switch of the cement pressure tester and turn on the power supply (the red light is on at this time).

⑷ Turn on the oil cylinder motor (that is, press the green indicator button, and the green indicator light is on at this time). Unscrew the oil feed valve to raise the piston for a period, then adjust the finger to zero and stop the oil pump motor (press the red button).

⑸ Start the loading speed indicator motor and quickly adjust it to the appropriate position. At this time, the indicator disc maintains a certain speed and rotates (measured with a stopwatch). For example, if the loading speed is 2.4KN/s and the range is 0-300KN, the indicator disc speed is 0.48 r/min.

⑹Put the test piece.

⑺ Start the cement pressure test oil pump motor (the green light is on at this time), quickly adjust the oil supply valve handle to the corresponding position, and keep the pointer and indicator plate rotate synchronously when the test piece is loaded until the test piece is crushed, close the oil supply valve, and stop the oil pump motor and loading speed indicator motor.

⑻Record the test value.

⑼Open the oil return valve and turn back the driven needle.

⑽ Turn off the load speed indicator knob (be careful not to turn the indicator disc regulator).

⑾Clear the crushed specimens.

2. Characteristics of cement pressure testing machine

1. The cement pressure test machine adopts high-precision sensor and digital control valve, and the microcomputer is fully automatic to automatically detect breaking.

2. The entire Chinese interface of the cement pressure test machine is simple to operate, and the interface is intuitively displayed: force value, peak value, loading speed fluctuation, force and time curve, which test block is currently in this group, etc.

3. A laboratory networking database is available. If the network is connected, you can extract the data directly from the database without changing the software or host part.

4. The report format can be designed by yourself according to user requirements, and a special form template writing software is installed in the machine.

5. The form provides a manual filling box, which can reflect the external conditions of the current test in the report.

6. The cement pressure test machine is randomly equipped with a color HP printer, which directly prints out the A4 format report and stores it automatically.

7. The compressive curve, force value and automatically converted MPa value of each test block will be reflected in the table.

8. The cement pressure test machine does not need to be debugged, and it can be operated smoothly, and it can be refueled or connected to power.

10. The machine is simple to calibrate and can be calibrated according to the "Instructions for Use".

Before using any test machine, you must fully understand the performance of the product so that you can better achieve human-machine running-in during operation. This improves production efficiency.
