Take a look at what this description about liquid pumps means!
Thread Content
I’m reading a paper on liquid pumps, and there’s a paragraph I don’t understand. Could you help me out? “(2) The liquid pump inlet filter is clogged. Solution: Install a flare outlet below the inlet pipeline of the liquid oxygen pump to promptly discharge impurities before the pump filter, change the heating process of the liquid oxygen pump from reverse to forward heating, and clean the filter when the inlet resistance exceeds 50 L/Pa. ” In this passage, it is asked how to install a flared fitting below the inlet pipe, and also add a valve “What are the advantages of changing from reverse heating to forward heating?
I don’t understand. First of all, how is a liquid turned into liquid oxygen?
I’m sorry, I wasn’t clear enough; in the field of air separation, the liquid pumps in question should be accurately referred to as \"cryogenic liquid pumps\", which include liquid oxygen, liquid nitrogen, and liquid argon. Let’s take the liquid oxygen pump as an example here!
It involves adding a purging valve at the inlet, but it is estimated that a branch pipe fitting will need to be welded in order to perform purging before starting the pump each time.
Positive heating here refers to the heating air being blown from the outlet to the inlet, right? . . It’s usually like this; heating also helps to remove impurities.
Unlike reverse heating and forward heating, based on the description, blowing from the outlet toward the inlet should be reverse heating.
Estimation probably refers to the blow-off valve~~
It can’t be that simple. You say this is a standard configuration, so there’s no need for them to specifically mention such modifications!
OK, once I find the answer, I’ll let everyone know. . . Hehe. . .
