【Q&A Question 229】August 17, 2017: Explain the meaning of each symbol in 100YⅡ-100*24. The reference answers can be seen after responding; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) 100 – Inlet diameter (millimeters); Y – Single-stage centrifugal oil pump; II – Material code; 100 – Rated head of the pump per stage (meters); 2 – Number of stages; A – Outer diameter of the impeller after the first machining. Scoring criteria: Incorrect answers result in 2 points; incomplete answers earn 3–8 points. Correct answers with a detailed explanation grant 10 points, while correct answers with additional supplementary information yield 15–20 points. Please use these criteria for scoring. Note: If there are editing records after answering, only those who participated will be given points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters unrelated to the answer are all considered malicious spamming; points will start to be deducted after three warnings. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Petrochemical Sector – “Creative Ideas for Energy Savings” Campaign (Second phase is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html 2017 Coal Chemicals – “My Technical Upgrades” http://bbs.hcbbs.com/thread-1786290-1-1.html
What do the symbols in 100YⅡ-100*24 mean? 100—— diameter of the suction pipe; Y—— single-suction horizontal Y-type oil pump; Ⅱ—— material of category II; 100—— flow rate; 24—— head
What do the symbols in 100YⅡ-100*24 mean? 100—— diameter of the suction pipe; Y—— single-suction horizontal Y-type oil pump; Ⅱ—— material of category II; 100—— flow rate; 24—— head
100 – Suction port diameter (millimeters); Y – Single-stage centrifugal oil pump; II – Material code; 100 – Rated single-stage head of the pump (meters); 2 – Number of stages; 4 – First machining of the impeller’s outer diameter
100 – Suction port diameter (millimeters); Y – Single-stage centrifugal oil pump; II – Material code; 100 – Rated head of the single stage of the pump (meters); 2 – Number of stages; A – First machining of the outer diameter of the impeller
In the formula: 100 – inlet diameter (millimeters); Y – single-stage centrifugal oil pump; II – material code; 100 – rated head of the pump per stage (meters); 2 – number of stages
100 – Suction port diameter (millimeters); Y – Single-stage centrifugal oil pump; II – Material code; 100 – Rated head of the single stage of the pump (meters); 2 – Number of stages; A – First machining of the impeller’s outer diameter
100 – Suction port diameter (millimeters); Y – Single-stage centrifugal oil pump; II – Material code; 100 – Rated single-stage head of the pump (meters); 2 – Number of stages; A – First machining of the impeller’s outer diameter.
100-Inlet diameter (millimeters)； Y-type single-stage centrifugal oil pump ； Ⅱ Material Code ； 100-Rated single-stage head of the pump (meters) ； 2-Series
There’s a problem with the question itself; it should be 2A at the end, not 24!
