What is the role of industrial chillers in the vacuum coating process? Vacuum coating works at a high temperature membrane surface evaporation falling crystals. As the air for evaporation of the membrane molecules will produce resistance caused by collision to make crystals become rough dull, it must be under high vacuum in order to make fine crystal bright, if not high vacuum will lose luster crystal bonding force is very poor. Early vacuum coating is to rely on natural evaporation body scattering, combined with low gloss poor poor ergonomics. Now add frequency magnetron sputtering target magnetron target shooting film of precursor molecules will evaporate under the influence of an electric field to accelerate the bombardment target, a large number of target atoms sputtered, neutral target atoms (or molecules) is deposited a film on the substrate, can not be solved in the past natural evaporation process of membrane species, such as titanium zirconium oxide and the like. IF equipment cooling water must be added, because of its high frequency current is large. Currents flowing in a conductor skin effect, the charge will be gathered in the conductance have surface area, so that the conductance heat pipes do so using the hole conductors middle water cooling. (Mainly cylindrical target) Why should water cooling? Magnetron sputtering target at launch will generate heat will deform a gun, so it has a water jacket for cooling a gun. At the same time there is an important reason may magnetron sputtering coating technology is considered one of the most prominent achievements. It sputtering rate, the substrate temperature is low, the film - substrate with good adhesion. From a deeper study the movement of electrons in a non-uniform electromagnetic field and to explore the more general principle of magnetron sputtering and transverse magnetic field inhomogeneity and symmetry is the essential reason for magnetic confinement. Magnetron sputtering coating can be considered one of the most outstanding achievements of technology. It sputtering rate, the substrate temperature is low, the film - a good base bonding force, stable performance of the device. Chiller Common Cause Failure Analysis and Troubleshooting chillers use a long time, it will inevitably have some fault, then we will produce according to the phenomenon of these failures, to analyze the causes of failure, find troubleshooting methods. A, industrial chiller capacity to mobilize for incorrect reasons:..... 1 temperature is too low, the oil viscosity is high; 2 capillary obstruction; 3 capacity control solenoid valve opening blocked; 4 capacity control piston ring wear; 5 content transfer passage obstruction; 6 oil filter blockage; 7 insufficient amount of lubricating oil (oil level less); 8 temperature switch fault system; B, industrial chillers abnormal vibration or noise, this phenomenon reasons The following are several, one may be bearing damage, replace bearings; 2. friction between the rotor and the casing or friction, inspection and repair or replacement of a screw; 3. emit electromagnetic solenoid valve sound, replacement or repair; 4. internal fixed parts loose screws, tighten the screws; 5. internal parts loose, tighten. 6. There is a foreign object enters the compressor, remove foreign bodies. C, when the expansion valve for liquid has been uneven, because: 1 Turn degrees superheat too small, adjust the opening superheat; 2, temperature of improper position or balance pipe location, a reasonable choice of installation location; 3 selection... excessive expansion valve, replace capacity suitable expansion valve. Hot and cold machine using the main features of the highest in Europe and America imported compressor head brass welding method using anaerobic heating power switching function RS485 communication function for automated management (optional) electrical use OMRON, FUJI, TE, LG, MOELLER, ABB temperature control range: water temperature + 5oC-98oC stainless steel integrated pipelines for less pipe resistance and rust using imported components, life is long control mode: imported for the computer or PLC (optional) Perfect safety protection, fault indication, maintenance, maintenance without professional high efficiency evaporator, can save more energy than 30% C-10 uses two compressors used independently or together.
