How should the parts in red be translated?

The compressor supplier must ensure that significant pressure drops within the allowable limits are included in the performance data; reference is made to the attached sketch. 3. Water in the recirculating gas: Under abnormal operating conditions, up to 1000 ppm of water vapor may be present. 4. The startup conditions are defined as follows: For the make-up gas section, the head pressure must be as specified, with the compressor operating at its minimum required speed and at a minimum stable flow rate – that is, at the control line level. For the recirculation section, the inlet conditions must meet the specified requirements, with the compressor operating at a stable flow rate – again at the control line level – and with the kick-back valve closed.
1. . . . Points to normal indicators. (I’m not entirely sure; it says on the internet that “normal head” refers to a “normal water head,” but I’m not aware of what that means.) 2. The attached sketch can be used as a reference. 3. Appear. 4. The startup phase is specified as follows: For the air replenishment unit, ? The head (it’s not clear what this specifically refers to) must be specified according to the minimum requirements for the compressor’s operating speed as well as the minimum standards for stable flow control. In the circulation unit, when the control valve and check valve are closed, the conditions for entering the circulation process must be specified based on the compressor operating under stable flow conditions.
There are many types of compressors; I’m not sure what kind your compressor is Reciprocating? Centrifugal? Then everyone can answer.
Is the centrifugal normal head a normal head pressure?
normal head standard head or conventional head
Normal head refers to the discharge pressure of the compressor
Then how should the other red-texted parts be translated?
1. Conventional indenter 2. Attached in the sketch. 3. Discuss, address. 4. The rules regarding driving are as follows:
The antisurge valves should be closed within the specified flow range corresponding to normal head pressure. For information on surge, you can refer to this post: http://www.compressor.cn/Service/HTML/20061214100413_31658.html This is a very important topic; please keep discussing it so it doesn’t get ignored.
W moderator specializes in compressors; everyone is waiting for you to speak so they can learn some real things Besides, the parts marked in red aren’t that difficult, right? It’s not clear which parts are “very meaningful”? Also, may I shyly ask what “meaningful” means? :funk:
The start-up case is defined as follows: This sentence should state the relevant regulations for the heating and reduction process, rather than the regulations regarding startup.
