The utility model discloses a kind of
refrigerant water automatic sampling detection
alarm device, comprising:
liquid storage tank,
pressure sensor, liquid level controller,
conductivity controller,
vacuum pump and PLC controller.The utility model realizes
refrigerant water detection full-process
automation, through PLC device accurate linkage
pressure sensor, liquid level controller,
conductivity controller,
vacuum pump and
solenoid valve, sampling, detection and reset are automatically completed according to set period, without manual intervention throughout, greatly improve detection efficiency.
Conductivity controller real-time detects the
conductivity of
refrigerant water, immediately triggers alarm once exceeding, effectively avoid the unit failure caused by refrigerant
water pollution.After detection is completed, sample in
liquid storage tank can be automatically
backflow to
evaporator, save manual
processing link, reduce labor intensity, ensure whole process stable and reliable, data accurate simultaneously, provide powerful guarantee for safe and efficient operation of
refrigeration unit.
