The grouting recorder often has various problems during the construction process. Is it difficult for you to solve it if you do not understand the technology? Below, Tianjin Saizhi Grouting shares the common fault diagnosis and troubleshooting methods of the grouting recorder to help you quickly diagnose the fault of the grouting recorder. , fast and normal construction.
Common fault diagnosis and elimination methods of grouting recorder
1. There is no response when starting up.
Check whether the main power switch fuse, power cord and other
power switch fuses are open circuited, and whether the power cord is well connected.
2. The grouting program cannot be started and the
xxx file cannot be found
, please consult the manufacturer's after-sales service hotline.
When an illegal user prompts to
log in, the program automatically exits
3. The computer crashes and an unknown error occurs.
Shut down and restart the computer
4. No pressure display
program parameters (pressure zero and gain) are set correctly Whether
the positive and negative poles are reversed whether the
8-pin plug corresponds to the corresponding Whether the channel
host has a 24V power supply (use a multimeter to measure whether its output DC voltage is 24V). When there is a 220V AC voltage input, but there is no 24V DC voltage output, it can be judged that the 24V DC power supply is damaged, and the DC power supply of the same specification should be replaced.
Whether the signal line is open circuit (whether there is 24V DC voltage on the positive and negative terminals of the multimeter pressure sensor) whether the
oil slurry isolator is short of oil, whether the piston or leather cup is stuck, whether the viscous
pressure sensor is damaged (replace)
5. Pressure display value ratio Whether the oil slurry
isolator is too large (or can not be reset to zero) is too much oil Whether the positive and negative poles of the meter signal line are connected reversely Whether the flowmeter is reversed in the pipeline (the flow direction of the slurry should be consistent with the flow direction of the arrow on the flowmeter ) Whether the program parameters (flow zero point and gain) are set correctly Whether the 8-pin plug corresponds to the corresponding channel signal line Whether the circuit is open
The flowmeter is damaged (replace)
8. Whether there is a large amount of cement agglomeration in the flowmeter that the flow display value is smaller than the actual value
(remove and clean)
9. Whether the pressure and flow fluctuation value is relatively large, whether the
signal line is entangled with the power line
, and collect the parallel port data after the chassis Straighten the wire and separate it from other wires.
10. Inaccurate density. Whether the density sensor is solidified by
cement .
Recalibrate according to the density sensor calibration method
