【Q&A Question 075】July 4, 2016: What are the hazards when the pressure in the raw material buffer tank is too low? The answer key can be seen after responding; scoring is based on identifying the key points. 1. The head pressure of the feed pump is low, which can easily cause the pump to empty ； 2. The flow rate of raw materials from the upstream unit may increase ； 3. Too low a pressure may cause the light components in the raw material to flash off.
Poor buffering effect, large fluctuations at the outlet
The pump has difficulty reaching high flow rates, and it tends to go into vacuum, which can lead to interruptions in the supply of raw materials.
When the liquid level in the raw material buffer tank is too low, it causes low pressure at the pump’s suction inlet, resulting in the pump running dry, a disruption in feed supply, and damage to the pump’s mechanical components.
Due to insufficient supply, backflow is likely to occur
