Product Description


Liquid Nitrogen Sub Zero Treatment Cryogenic Processing Freezer Cryogenic Treatment Equipment


Ultra-low temperature cryogenic refrigerator, also called cryogenic treatment ultra-low temperature refrigerator, refers to a cryogenic treatment tank that uses a mixed working fluid as a refrigerant to process workpieces at a temperature below -130°C. It can significantly improve the toughness of the workpiece without reducing the strength and hardness of the workpiece. It can effectively improve the mechanical properties and service life of steel materials, non-ferrous metals and composite materials, stabilize the size, improve uniformity, reduce deformation, and be easy to operate, without damaging the workpiece, without pollution, and low cost. It has a positive application prospect and Expansion capacity.
The equipment can significantly increase the hardness and strength of the workpiece, ensure the dimensional accuracy of the workpiece, improve the wear resistance and impact toughness of the workpiece, and improve the internal stress distribution of the workpiece; it is mainly used for cold shrinkage of copper sleeves and bearings, and is widely used in precision mechanical assembly Application in industrial cold treatment, mainly embodied in the application of cold work die steel and high-speed steel, bearing steel, cold work die and die parts; in large equipment (automobiles, large construction machinery, aircraft parts, aerospace equipment parts, military equipment Components) Ultra-low temperature testing also has a wide range of applications.
 
Ultra-low temperature cryogenic box
 
   Next, let's get a deep understanding of the ultra-low temperature cryogenic box!
  Insulation system:
  Insulation system consists of air-filled pipe insulation system and box insulation system. The box body insulation system is composed of a special insulation layer, the thickness of the insulation layer is 150mm, and the thickness of the special requirement can reach 200mm, which can effectively block the heat and cold exchange inside and outside the box to reduce the consumption of liquid nitrogen. The upper cover and the box body are equipped with elastic silicone ring and wool felt double-layer seal, equipped with an adjustable locking device, and the temperature of the outer wall of the box does not exceed 10°C from the room temperature.
  Control System:
  The control system is composed of button switches, relays, intelligent temperature controllers, temperature sensors, recorders, pneumatic opening switches, etc. The selected temperature control instrument has PID automatic adjustment function, and multiple process curves can be set. Each curve can be set step by step. After all procedures are completed, it will automatically alarm and power off. Electrical operation is divided into manual and intelligent instrument control. It can be switched through the manual/automatic selection switch on the control cabinet panel and can be switched during the operation of the equipment. Equipped with electric interlock and alarm to ensure safe use. Independent electric box, man-machine input, PLC intelligent control can be designed for special requirements.
  cooling system:
   The cooling system is composed of an external liquid nitrogen bottle, a gas filling pipe, and a solenoid valve, a disperser, a stirring fan, and an exhaust hole in the equipment. The system uses the principle of sublimation of liquid nitrogen to absorb heat and heat balance to achieve refrigeration, and the flow of liquid nitrogen is controlled by a solenoid valve; the stirring fan adopts a vortex fan with a reasonable circulating air duct, and it can also maintain cold air even when workpieces are stacked in the box. Orderly circulation can ensure the uniformity of the temperature of the ultra-low temperature cryogenic box.
