How to do when the temperature of the freezing and cooling oven is not cooling

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.

XS Hub Centric Rings, designed to fill in the gap between the hub of the car and the center bore of the wheel for averting vibration. There ar two kinds of material used, one is PE, another is T6-6061 aluminum.


why Hub Ring? O`Rings / Spigot Rings or Alloy Wheel Hub Centric Rings are designed to fill in the gap between the hub of the car and the center bore of the wheel. Most wheel manufacturers design their wheels with a center bore large enough to fit on most cars. Therefore, since wheel manufactures make their center bore large enough to fit most cars, most wheel fitments have a gap between the hub and the center bore.This gap usually doesn't allow for the wheel to fit hub centric but rather lug centric which causes vibration. Therefore, to fill the gap and ensure the fitment is hub centric, hub rings are used.
