equalizing line

This depends greatly on context. What is your specific situation?

I'm gonna take a stab at this one generically.

The equalizer line equalizes the potential energy differential between two energy sources.

So, all you have to do now is define the type of energy you want to equalize.

That will define the line.

in between the ejector condensor and the hot well there is an equalizing line i want to know its purpose

2. Does the hot vapour bypass betweent eh condensor and the reflux drum serve the same purpose ass the equalizing line in an ejector condensor system?

Tornado?

Awaiting further input from the OP. Post 2 has some verbiage, but no P&ID to illustrate the meaning of the terms. As of the moment, I do not picture the process in question.

Whatever the process is, there may be valves that cannot or should not be opened suddenly against large ΔP. A common technique is to provide a small bypass equalizing valve and line around the main valve.

In a different context, refrigeration systems with multiple condensers may require certain portions of the condenser inlet and outlet piping to be pressure-equalized. Full details would be lengthy to describe.

what is the purpose of asking such stupid questions without first detailing your application.

Dear Guest,

WHENEVER YOU want to extract or pump any liquid under FULL vaccuum or Partial Vaccuum, you have to provide EQUALISING LINE so that the Liquid will enter the pump for suction and pump it out.

There is specific calculation for the EQUALISING SIZE. Orelse the pumping LIQUID UNDER VACCUUM will be a problem. THEREFORE EQUALISING LINE IS REQUIRED.

For this application my ducon condensate power pump is "ideal" to pump liquid under vacuum condition. The 1" exhaust of the pump is connected as the equalizing line.

This has a vide application in sugar mills at the multiple-effect evaporators in draining condensate under vacuum condition. (my avtar has a photo of the pump and by web page: duconems.com details more).

Sorry i'm not advertising but informing an equipment to suit this application.

Dear Mr. Ducon,

The web page referred by you is not opening. Please provide details to this CR4 Link. aCTUALLY THE SIZE OF THE EQUALISING PIPE HAS GOT A DEFINITE CALCULATION FOR ARRIVING AT THE REQUIRED SIZE.

It is www.duconems.com . It should open for i pay annually and regularly.

Yes I know about the size of the equalizing line deteriming etc., but in this power pump it is actually breaking the vacuum in MEEs for the condensate to enter the pump.So this pump drains each EEs under vacuum.

You can also see similar pumps in websites of: spirax sarco, armstrong international, bestbell, adca etc.

If you go to www.youtube.com and type"duconems" on search and click you see all ducon pumps in operation lifting condensate from machine/sets of machines to boiler feed tank but none on multiple effect evaporators(MEE).

If you type"spirax condensate power pump" on youtube-search you can see an animation.

It's there to make any Anonymous Poster publish a Piping and Instrumentation Drawing in a thread so as to elicit further help from this forum.
