Small Drain is clear but if water covers the hole fast enough it won't drain. If slowly water comes in it creates a siphon.

I have a drain with a 1/4in opening and hose attached it is at a 90 degree angle. My problem is the drain will not work if water enters the channel very quickly and covers the hole completely. I have noticed that there will be a pool of water in front of the drain sometimes and will not drain then it overflows.
I tested the drain and when water enters the channel to drain it works fine and even creates a siphon if there is a lot of water constantly draining. My problem is if water quickly covers the opening it will somehow not drain. I assume this has a fancy term in the hydraulic world but I need to know how to fix it. The drain hose/line is clear and drains perfectly when water enters slowly. Even if I pour water in and it covers the drain, but only after it has started to flow. If I cover the drain very quickly with water it seals with air pressure or something..
Any ideas of what this phenomenon is called or how to fix it? I was thinking of putting a pin hole in the top of the drain line at the entry.
Thanks in advance

What is this draining?

 

[ThankYou]

I seemed to have solved my problem. I read about adhesion, cohesion, and surface tension of water and learned a lot. The drain surface was rough and dirty causing strong cohesion and adhesion. The dirt may have also caused increased surface tension.
There was also a thin plastic lip around the drain (from the manufacturing process) that I shaved off with a razor. All of this lead to the water forming a strong sphere at the entry of the drain creating a plug (I know it sounds weird, but cohesion causes this and adhesion makes it easier to stay plugged). Cleaning with soap dish soap seemed to solve the issue. I am considering waxing the surface, but I need to read more about the fore mentioned properties to make sure it will help.
Most plumbing drains are highly polished so I believe it should help.

Is it a drain with small holes, we have commercial grid strainers at work and if you make the water swirl it drains fine but it will act clogged some times like you said
