Cold principle of industrial cold water mechanism

  Industrial ChillerSystem, in addition to refrigeration compressors, the static equipment to meet the basic principles of refrigeration is usually called the main equipment, such as condensers, evaporators, to ensure the rest of the system functions of static equipment, said ancillary equipment, such as liquid storage, vapor-liquid separator, low-pressure circulation barrels.

1: Chillers are pressure vessels, before installation should pay attention to check whether the factory provides pressure vessel completion drawings (such as in the original blueprint to modify, you must have the modification, technical auditor to confirm the mark, and covered with the stamp of the completion plan), product quality certificate, pressure vessel product safety and quality Supervision and inspection certificate. The manufacturing unit of pressure vessel compression element shall provide technical information to the user in reference to the relevant content of the product quality certificate. The construction unit shall also provide the technical documents and materials mentioned above when the pressure vessel of the field group welding is completed and inspected. In accordance with the relevant provisions, will also provide group welding and quality Supervision and inspection of technical data. Of course, the welding personnel of the field group welding pressure vessel must have the corresponding professional certificate.

2: After the cold water machine to the scene should be checked and properly maintained. The seal should be sealed open to prevent dirt from entering and reduce rust. Placed too long to set, prepare, before the installation should check whether there is rust or dirt pollution, and compressed ③ Irrigation Foundation to the specific equipment of the screw hole position layout model, and embedded anchor bolts. The model must be flat, the size must be correct, and the horizontal ruler check level. When pouring concrete, the position of the anchor bolts cannot be moved.

3: Low-temperature chiller installation, in order to minimize the "cold bridge" phenomenon, on the basis of additional mat wood. Use of the mat wood should be cooked in the asphalt in advance to prevent decay. There should be enough air around the cryogenic equipment to ensure the construction of the insulating layer. Cryogenic equipment and its connected valves should leave the thickness of the insulation layer, so as to avoid the valve is immersed in low-temperature equipment insulation layer, affecting valve operation and maintenance work.
