The frozen cryogenic oven has the advantages of compact structure, intelligent control of the microcomputer, touch soft keys and stainless steel liner. It can provide users with a hot and cold controlled field source with constant temperature and constant temperature, constant temperature test or test on test samples or products, and can also be used as heat source or cold source for direct heating or cooling and auxiliary heating or cooling. . The air-cooled, totally-enclosed compressor unit of the frozen cryogenic thermostatic chamber cools and cools rapidly. Changzhou Gold Instrument Manufacturing Co., Ltd. combines many years of experience in the production of frozen cryogenic constant temperature baths. What to do if the freezing and cooling temperature bath cannot cool down: 1. If it is a cascading unit, observe if both units are in operation. If one of the units is not in operation, it should be stopped immediately. Find out why the compressor is not working and analyze it. 2. Check if the voltage is supplied to the compressor. For example, is the AC contactor connected to the compressor unit is in contact with the compressor? Are the wires connecting the compressor disconnected or the connection is not good? And judge whether the voltage reaches the rated voltage of the compressor. 3. To judge the current of the compressor in the freezing cryogenic temperature bath, the current must reach the rated current of the compressor. If the voltage is normal, the current does not meet the requirements, indicating that the refrigerant (refrigerant) is missing. 4. Observe whether the cooling fan of the condenser is working. Is the steering of the cooling fan normal? When working normally, the direction of the wind should be blown. 5. Whether the compressor is in shortage of refrigerant, use a pressure gauge to observe whether the pressure after starting the equipment working compressor is normal, or touch the temperature of the high pressure exhaust pipe of the compressor. Normally, it should be very hot and hot. In the case of dual-unit cooling, it is necessary to determine which compressor is deficient in refrigerant. Spunbond Nonwoven Production Line The polyester PET non-woven production line is used for the production of non-woven fabrics such as polypropylene spinning, web forming, and hot rolling reinforcement. Using polypropylene as the main raw material, supplemented by color masterbatch, anti-oxidation, anti-pilling, flame retardant and other auxiliary agents, it produces PP spunbond hot-rolled non-woven fabrics with different colors, properties and uses, and polyester spunbond and hot-rolled non-woven fabrics. It has the excellent characteristics of high strength, low shrinkage, heat resistance, good stability, breathable waterproof, flame retardant, acid and alkali resistance, moth-proof, non-toxic and anti-ultraviolet.
