Precautions for Leakage Inspection of Glycol Chiller
The main points about checking leakage of glycol chiller During the operation of the glycol chiller, it is critical that the refrigeration system does not leak.
In order to avoid the leakage of refrigerant and other gases from the glycol chiller, the inspection of the welding quality is more important. First check whether the sealing performance of the weld is good. After adding refrigerant or nitrogen and allowing it to stabilize for a certain period of time, it can be tested with soapy water or other methods. When the refrigeration cycle is in operation, the welds should not be cracked due to vibration, the pipes should not be blocked by debris during welding, and should not enter moisture due to improper operation. When the refrigeration cycle is working, the surface of the welded parts should be clean and clean. No oil stains.
The common leakage points of glycol chillers are evaporator leakage, refrigeration cycle connection leakage, refrigeration cycle valve leakage, compressor pipeline leakage, capillary vibration wear, four-way reversing valve leakage, etc. Common inspections Leakage methods are commonly used in the production and maintenance of refrigeration cycles: visual leak detection, pressure leak detection, instrument leak detection, vacuum leak detection, etc. The user can solve the leakage points one by one.
The fault of leak detection of glycol chiller is relatively common. Therefore, when choosing, it is recommended to choose a fully closed loop piping system and valve parts to choose branded accessories. The evaporator uses a high-power plate heat exchanger, which is small in size, high in efficiency, fast in cooling, safe and reliable, and is used for rapid liquid cooling. It is widely used in petrochemical, medical, pharmaceutical, biochemical, freeze-drying, pharmaceutical, military and other high-tech industries.
February 6, 2021If you need equipment to distill CBD, you need to scrutinize your choices, as the equipment can vary in its features and design. When you use equipment that produces a CBD distillate, you want to seek out a system made by a manufacturer that provides proven and reliable products. You should also work with a business that can train you on the use of the equipment you buy.view
