Fill-in-the-blank question: The possible reasons for low pressure or even negative pressure in the inlet main pipe of the vinyl chloride screw compressor are: ( ), ( ), ( ). Answers: water accumulation in the pipeline, excessive gas extraction, and liquid seal in the caustic washing tower.
The reasons for low pressure in the inlet main pipe or a negative pressure there may be: ( ), ( ), ( ). Answer: Water accumulation in the pipes, high air extraction volume, liquid seal in the caustic scrubber.
1. High moisture content in the system leads to low-temperature ice blockage after throttling; there is no refrigerant on the low-pressure side, resulting in low pressure/underpressure. 2. There is a lot of dirt in the system; the throttling mechanism is blocked, there is no refrigerant on the low-pressure side, resulting in low pressure/negative pressure. 3. During system welding, weld blocks cause circular blockages within the system; there is no refrigerant on the low-pressure side, resulting in low pressure or negative pressure.
The reasons for low pressure in the inlet main pipe or even negative pressure may be: (high moisture content in the system), (excessive dirt in the system), (blockages formed due to welding defects, which disrupt circulation within the system)

Water accumulation in pipes, high exhaust volume, liquid seal in the caustic scrubber tower
Water accumulation in pipes, high exhaust volume, liquid seal in the caustic scrubber tower
Pump failure, leakage, or excessive usage
The reasons for low pressure in the inlet main pipe or a negative pressure condition may be: (low inlet flow), (low inlet pressure), (pump installed at too high a position)
