Construction quality monitoring system, intelligent grouting recorder
Instrument Name: Grouting Recorder
Instrument model: JT-E6 (English version)
Product Introduction
The grouting recorder integrates microcomputer technology processing, a seven inch true color touch screen, parameter display, setting, and printing functions. It can record the flow rate, pressure, density, and time during the grouting process without the need for buttons or a mouse, making it simple and intuitive. Parallel port printers can be used on-site for printing, and data export and archiving with USB drives are also supported. The grouting automatic recorder is available in two models: one trailer and one trailer. Suitable for curtain grouting, karst grouting, compaction grouting, double liquid grouting, consolidation grouting, backfill grouting, joint grouting, anchor grouting, high-pressure rotary jet grouting, multi head small-diameter deep mixing piles, highway maintenance grouting and other series of grouting processes.

Product Features
1. Widely used in various grouting processes such as curtain grouting, karst grouting, consolidation grouting, high-pressure rotary jet grouting, GIN grouting, prestressed grouting, and simple water pressure, conventional water pressure, five point water pressure, punching, etc;
2. Adopting an integrated design, the key components of the instrument are made of imported electronic components, which can effectively prevent moisture, dust, shock, and electromagnetic interference. It is equipped with a built-in stabilized power supply and suitable for construction sites with scattered workfaces and harsh environments, such as tunnels, subway entrances, etc;
3. Supports 1 channel and 2 channels, with options for two parameter small loop, two parameter large loop, three parameter small loop, and three parameter large loop. The software automatically recognizes them without the need to change settings;
4. The interface adopts a 7-inch LCD screen display, full English prompts, and can query historical grouting records;
5. Real time display of all grouting parameters for two grouting channels on the same screen;
6. Data automatic power-off protection, work can be restored upon incoming call.
Installation diagram of grouting automatic recorder:
Troubleshooting of grouting automatic recorder:
| Common fault cause analysis table |
| Fault phenomenon | Possible causes | Removal method |
| The actual flow rate of the electromagnetic flow meter is shown to be zero | 1,The actual flow direction of the fluid is opposite to the direction indicated by the sensor | Change direction of sensor installation |
| 2,Electrode signal to ground short circuit | Damage or break of signal cable insulation |
| 3,No excitation current | The excitation cable is broken or damaged |
| 4,The electrode is completely covered by insulation | Clean the electrode and remove the covering |
| The actual flow of the electromagnetic flow meter is stable and the indication value is unstable | 1,The measured fluid is not filled with a measuring tube | Change the position and manner of sensor installation so that the fluid is filled with the measuring tube |
| 2,The fluid under test contains more bubbles or oil | Remove bubbles or oils |
| 3,Sensor ground fault | Sensor grounding |
| 4,The electrode is heavily covered by insulation | Cleaning electrode |
| 5,The power supply is unstable and the interference is large | Separate power supply or anti interference stabilized power supply |
| 6,There is a strong interference device nearby | Change installation location to avoid interference sources |
| The pressure transmitter and the density sensor are not displayed or unstable | 1,Is the input voltage switched on? | Reconnect voltage |
| 2,Input voltage positive and negative connection | Changing voltage plus or Minus Voltage |
| 3,Sensor bad | Replace sensor |
| The pressure transmitter and the density sensor display very large and do not change | 1, Sensor bad | Replace sensor |
| The pressure transmitter and the density sensor display unstable or almost zero | 1, Is the sensor joint sealed? | Re seal |
