Participation earns 4 points of wealth! 10 wealth points as a reward for correct answers or in-depth discussions! :Lol Question: If the system isn’t leaking but the vacuum level still isn’t achieved, what could be the reason? :o Answer: 1. The vacuum pump is damaged ； 2. Water ring vacuum pump lacks water ； 3. Blocked pipelines =============================== Promotion of petrochemical-related activities: ☛ Notice on the launch of the large-scale event “I’m saving energy; where are you?” in the petrochemical area: http://bbs.hcbbs.com/thread-1579199-1-1.html (Source: Haichuan Chemical Industry Forum) This event offers awards in both text and image categories. When there are over 200 entries, an additional grand prize will be awarded, worth 600 Haichuan coins; if there are more than 300 entries, the grand prize value increases to 1,000 Haichuan coins, and if there are 500 entries, it rises to 1,500 Haichuan coins. First prize: 3 Haichuan commemorative water cups. Second prize: 5 winners, each receiving 120 Haichuan coins. Excellence awards: several winners, each receiving 200 wealth points. --------------------------------------------------------------- ☛ “My plant, my home” – Photo competition (10 wealth points per photo): http://bbs.hcbbs.com/thread-1495069-1-1.html (Source: Haichuan Chemical Industry Forum) --------------------------------------------------------------- ☛ Haichuan Freelancers’ large-scale “public welfare” event is now underway! http://bbs.hcbbs.com/thread-1576975-1-1.html (Source: Haichuan Chemical Industry Forum)
High evaporation load, large feed volume, low feed temperature
The working capacity of the vacuum pump, the temperature of the working fluid, the amount of circulating cooling fluid, the concentration of the working fluid, the water content in the raw material – that’s basically it
Vacuum pump damaged； Water ring vacuum pump lacks water ； The pipeline is blocked.
Volatile gases are released from inside the pipeline, and the saturated vapor pressure at the operating temperature is relatively high.
Answer: It could be that the vacuum pump is damaged, or there is a lack of water inside the water ring vacuum pump, or the pipelines are not unobstructed.
I don’t know much about polypropylene; it’s probably related to the gases generated by the reaction itself
