Small desktop sealed chiller troubleshooting solution

Small desktop sealed chillers will have more or less failures after long-term use, so how can the compressor be solved if there are some faults?

LNEYA specializes in the development and production of small desktop sealed chillers with a temperature control range of 5 to 35 degrees. The temperature of the heat transfer liquid can be adjusted, and the temperature control accuracy is high with an accuracy of ±0.1 degrees. The device uses branded accessories for stable performance and can work 24 hours a day.
The small tabletop sealed chiller can be applied to cooling the heat generating portion of the semiconductor manufacturing apparatus, cooling the heat generating portion of the laser device, and analyzing and detecting the cooling of the heat generating portion of the machine. Some models are specially upgraded, not only for cooling, but also for heating. The temperature control range can reach 5 to 50 degrees, which greatly improves the performance of precision cooling water circulation equipment.

The fault of the small desktop sealed chiller should be comprehensively analyzed from the data and materials of the battery test water cooling unit obtained by means of indicating instruments and watching, listening, touching, etc., to find out the basic causes of the fault and consider what kind of emergency measures should be taken. How to save time, save materials, and save money to troubleshoot.

For small desktop sealed chiller compressor failure In order to prevent compressor overload or overheating, the motor has built-in six PTC thermistors. Generally, L and N are power supplies, and 11, 14 are connected to the control loop.

As one of the core devices in a small benchtop sealed chiller, the condenser acts to transfer the heat of the refrigerant to the surrounding medium (water or air), condensing the high temperature and high pressure ammonia vapor into a liquid. For example, in the water-cooled box type water chiller, the condenser is a high-efficiency threaded steel pipe. The two end covers can be interchanged to change the direction of the water pipe. The water pipe process has multiple circuits, and each condenser and the compressor capacity are mutually The straight-through water pipe is easy to clean and maintain.

The small desktop sealed chiller is a heat transfer medium that uses cooling liquid (usually used as cooling liquid, low temperature common synthetic cooling liquid, such as aqueous solution of ethylene glycol, etc.) to transfer heat generated by other instruments or equipment that need to be cooled. The refrigeration system dissipates heat to the outside of the unit, ensuring that the unit operates within the normal temperature range.

For the failure of the small desktop sealed chiller, it is necessary to strictly follow the relevant safety procedures. Do not assemble it yourself if the situation is unclear, and disassemble it at will, and contact the manufacturer for repair.
