General buildings and routine maintenance
The integral EPTT is composed of 5 parts, namely, the control cabinet, cooling system, EPTT cabinet, laser and optics processing technique.
The gear can also be divided into five parts in phrases of capabilities, which are:
1) Laser supply
2) Laser EPTT offer
3) EPTs program
four) EPTTling program
5) Cooling technique.
The laser is a unit that converts the EPT vitality into the laser power. This EPTT emploEPTTNd3 :YAG Laser, consisting of the pursuing components:
a) EPTing lamp: it converts the EPT vitality into the optical strength that can activate the substances for laser processing. The EPTT adopts pulse xenon lamp with repetition charge of XMC7-125. Each the electrode and quartz EPT tube surface area need to be cooled in the course of operating.
b) Laser crystal: it converts the optical power into the laser vitality. This EPTT emploEPTTthe crystal #10928*145mm Nd3 : YAG as its doing work material.
Condensing cavity: it focuses the ligEPTT from the pumping lamp on to the functioning materials.
The optical resonant cavity can give optical comments, enabling the laser to be magnified to form substantial energy laser for output. This EPTT emploEPTTthe aircraft and pXiHu (West EPT) Dis.Hu (West EPT) Dis.lel cavity manufactured up of flat mirrors with EPT as its medium. The entire reflector’s transmit is considerably less than .four%, output reflecting mirror’s transmit is 85%.
Other elements: large voltage electrode, insulation base plate, positioning bracket, adjustable diaphragm frame and laser holder.
(2) Safety measures and servicing
As the EPTT is very precise gear whose discharging features the large pulse voltage and charging attributes the huge ability, and the laser concentrating vitality is very centralized, the operators should acquire professional knowledge and expertise ahead of they operate on the EPTT.
EPTal resonant cavity
The two medium diaphragms of optical resonant cavity are totally pXiHu (West EPT) Dis.Hu (West EPT) Dis.lel to the laser bar’s end face, touching or random adjustment is not allowed. Do not open the outer hood of the laser randomly and keep the optics surface area hugely clear. Normally, the large-power laser will hurt the diaphragm layer. When the laser output strength is lowered down, the operator must very first check whether the medium diaphragm is thoroughly clean. If any filth, he can use lens paper or cotton wool moistened by the cleansing agent (liquid mixture with ethanol absolute and ethanol respectively occupying fifty%, the very same when pointed out in the following portion) to thoroughly clean it gently. Then check out the resonant cavity to see if it is misadjusted.
The laser has one particular drinking water inlet pipe and a single outlet pipe, respectively connected to the cooling channels of the lamp and bar. Difficult h2o movement at any element will lead to large reduction. Every time when the equipment is assembled, the operator should check out the water movement at each route and make confident no fault eXiHu (West EPT) Dis.sts prior to beginning up the laser.
Xenon lamp substitution
The regular service time of the pulse xenon lamp is 10eight instances of blinking if it works unEPTTits rated EPTT and beEPTTs to the consumptive pieces. To guarantee the standard performance of the EPTT, the lamp must be replaced when it has reached its rated blinking instances (about ten8 occasions) and the strength turns into minimal.
In instances that the xenon lamp is destroyed or its services time is shorted thanks to other triggers (for example, it cannot pre-illuminate or no vitality output is available when the voltage is improved to 500V), the xenon lamp must also be replaced.
As the power of the sealing at the lamp’s two ends is relatively reduced and apt to getting destroyed, EPTT warning need to be supplied when substituting the lamp. The adhering to methods ought to be followed:
Switch off the EPTT, cut off the h2o source and discharge the remaining electricity on the energy-storage capacitor
Take away the electrodes of lamp
Remove the gland of lamp, meticulously pull out the lamp from the aspect of the full reflector
Use cotton moistened by cleansing agent to clean the sleeving
Check to see if the appearance, size and other factors of the new lamp is conforming
Put in the new lamp into the chamber, push the gland tigEPTT and mount the electrodes
EPT to the water source and verify the sealing of each component to see if they are reputable
Switch on the major EPTT to verify no matter whether the lamp can discharge generally
Try solitary place procedure, verify whether the output vitality of laser meet the specifications. If the output is not perfect, continuously change the resonant cavity
EPTT the laser with outer hood.
D.Nd3 :YAG crystal is the core component of the laser, and is fairly pricey. For that reason it should be mounted with fantastic care. The two conclude faces of Nd3 :YAG crystal bar is totally pXiHu (West EPT) Dis.Hu (West EPT) Dis.lel to every single other and has substantial cleanliness. If there is any pollutant on the stop faces, the luminous effectiveness will be lower, the facula mode will deteriorate, or even can’t illuminate typically. In that situation, the room housing this EPTT need to be cleaned and pros must be named for related therapy. EPTTke out the Nd3 :YAG crystal bar, use lens paper or absorbent cotton moistened by cleansing agent (liquid mixture with ethanol answer and yet another respectively occupying fifty %,) to get rid of the dirt carefully. The triggers leading to the harm of crystal bar can be described as follows:
a.The stream of cooling h2o is in excess of or interrupted, the strength input into the lamp helps make the lamp and bar overheated, which outcomes in the cracking of the lamp and bar
b.The stop experience is bumped, scratched or even damaged by challenging item
c.As the diaphragm layer is polluted , the bar is damaged when the substantial energy laser passes by
d.The bar is pressed way too tightly or the applied force is uneven when it is mounted, the in excess of substantial inside anxiety breaks the bar. In this situation, the operator must not open the hood of the laser, nor run the YAG bar. If the end encounter is discovered polluted, professionals need to be referred to as for the related treatment.
E.The condensing cavity doesn’t need upkeep work. Typically, it is not permitted to dismantle the condensing cavity.
F. Over voltage security
There are 3 varieties of voltage utilized to the pulse xenon lamp in succession, specifically, set off voltage about thirteen-eighteen kv, pre-burning open-circuit voltage 1500-1800 v and arc-discharge voltage about five hundred-2500 v. As a result, the lamp electrode should not get also close to other metallic objects, and a distance of much more than 15mm ought to be held. The insulation panel’s floor ought to be stored dry and thoroughly clean so as to keep away from pollutions which could reduce down the insulation efficiency to deliver brief circuit.
