Removing bubbles from laser tube

Submitted by kirill on Tue, 03/11/2014 - 10:53

Laser tubes should not be operated with air trapped within cooling piping as this can cause temperature hotspots and compromise integrity of the tube.

In ideal world, stream of water would remove all the bubbles but in our reci tube there are some welding spots where water becomes turbulent and traps pretty large air bubbles. This trapped air is very hard to remove.

To remove those you can:

Wait

If you wait long enough they will disolve themselves, but it can take hours!

Tilt

You can turn off chiller and tilt entire cutter, all you need to do is get bubbles moving couple of inches away from blocking spot. Obviously this method is only feasable if you have small cutter or someone really strong  (like Vladimir Putin) in your workshop.

Pump cycle

Turn pump on and off, quite often bubbles will move slightly from the deadlock place if you turn off the pump, catch this moment and turn pump again to remove the bubbles. This is quite tricky and does not work all the time.

Turbulences in water flow

Best way we found is to cause turbulences in water flow, all what needs to be done is to pinch and release incoming [from laser tube perspective] water hose once or twice, pinch will cause pump to build up pressure and when you release that pressure is going into the tube causing strong turbulences and removing bubbles. Our CW-5200 chiller pump is connected to coolant pipes using soft silicone joints, those can be easily pinched by hand.

Be careful when pinching, start gently, turbulences and overpressure caused by this are quite strong, if we pinch ours all the way we can almost feel cutter to vibrate on release. It can damage laser tube.

Je suis completement envoute par Riviera Casino, c’est un casino en ligne qui scintille comme un coucher de soleil sur la Cote d’Azur. L’eventail de jeux du casino est une veritable Riviera de delices, incluant des jeux de table de casino d’une elegance cotiere. Les agents du casino sont rapides comme un hors-bord, assurant un support de casino immediat et elegant. Les gains du casino arrivent a une vitesse de yacht, mais les offres du casino pourraient etre plus genereuses. Dans l’ensemble, Riviera Casino offre une experience de casino luxueuse pour ceux qui cherchent l’adrenaline glamour du casino ! Bonus le design du casino est un spectacle visuel mediterraneen, facilite une experience de casino luxueuse.

Les gains du casino arrivent a une vitesse explosive, cependant des bonus de casino plus frequents seraient explosifs. Globalement, Stake Casino promet un divertissement de casino brulant pour les pyromanes du casino ! De surcroit la plateforme du casino brille par son style explosif, ce qui rend chaque session de casino encore plus enflammee.

SEO backlinks for SEO are divided into anchor and non-anchor links.

Anchors include the main keyword, since the key query is fundamental for search engine ranking.

Non-anchor links are equally significant – they represent plain URLs, while user interaction plays a key role because it creates access for bots; search engines access your website along with internal pages, which is useful your project.

I provide semrush. When the number of links is limited for one of the services, updates are provided on the service with the highest count of inbound links as a result of indexing lag.

Ich bin vollig begeistert von SportingBet Casino, es pulsiert mit einer dynamischen Casino-Energie. Es gibt eine Welle an mitrei?enden Casino-Titeln, mit Live-Casino-Sessions, die wie ein Finale krachen. Der Casino-Kundenservice ist wie ein Starspieler, antwortet blitzschnell wie ein Schuss aufs Tor. Auszahlungen im Casino sind schnell wie ein Sprinter, dennoch wurde ich mir mehr Casino-Promos wunschen, die wie ein Sieg jubeln. Zusammengefasst ist SportingBet Casino ein Muss fur Casino-Fans fur Fans moderner Casino-Slots! Ubrigens die Casino-Seite ist ein grafisches Meisterwerk, Lust macht, immer wieder ins Casino zuruckzukehren.
