High and low temperature test box maintenance method

Maintenance method of high and low temperature test chamber 1. The temperature and humidity of the high and low temperature test chamber are important factors affecting the performance of the instrument. It can cause the corrosion of mechanical parts, reduce the smoothness of the metal mirror surface, and cause the error of the mechanical part of the high and low temperature test chamber. The performance is degraded; the aluminum film of the high and low temperature test chamber optical components such as gratings, mirrors, focusing mirrors, etc. is rusted, resulting in insufficient light energy, stray light, noise, etc., even the instrument stops working, thereby affecting the life of the high and low temperature test chamber, maintenance It should be corrected regularly during maintenance.

Second, the reasons for the frosting of the evaporator of the high and low temperature test chamber: (1) often open the test box door (2) check whether the box has air leakage. 3. After using a certain period of high and low temperature test chamber, the internal will accumulate a certain amount. Dust, the maintenance engineer or the engineer to open the high and low temperature test chamber cover regularly to carry out the dust removal work, and at the same time re-tighten the heat sink of each heating element, clean the sealing window of the optical box, if necessary Calibrate, clean the mechanical parts and necessary lubrication, and then restore the original condition, and then carry out some necessary testing, adjustment and recording.

4. Dust and corrosive gases in the working environment of high and low temperature test chambers can also affect the flexibility of mechanical systems, reduce the reliability of various limit switches, buttons and photoelectric couplers, and also cause the corrosion of aluminum film of components. one.

Oxygen Cylinder Filling System

ETR Oxygen Cylinder Filling System


By PSA principles, ETR PSA oxygen generators generate 93%±2% purity oxygen gas directly from compressed air. ETR oxygen cylinder filling plant is consisted of Atlas Copco air compressor, Parker dryer and filters, air buffer tank, ETR PSA Oxygen Generator, oxygen buffer tank, oxygen receiver tank, diaphragm oxygen booster, filling station and control cabinet.

Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±2% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure, then reach to 150bar to filling cylinders with an oxygen booster.
