The common reasons why water quality samplers fail to collect water samples and their solutions are as follows:
Hardware failure of the sampler
sampling pump failure : Check if the power supply is normal, confirm that the pump body is not clogged or worn, and contact professional personnel for maintenance if necessary.
Sampling pipeline blockage : Check if the sampling pipeline is blocked by foreign objects, and clean or replace the blocked parts.
Sampling bottle leakage or damage : Check if the sampling bottle is cracked, ensure good sealing, and replace it with a new one if necessary.
Operation setting issue
parameter setting error : Check whether parameters such as sampling time and speed meet the requirements and adjust them to a reasonable range.
Control system abnormality : Restart the device or update the control software. If the problem still cannot be solved, professional maintenance is required.
Environmental and maintenance factors
Environmental interference : Ensure that the sampler is placed in a dry and well-ventilated environment to avoid the influence of corrosive gases.
Improper maintenance : Regularly calibrate the equipment and replace aged parts to ensure stable performance.
