Start-up work for new energy thermal management
In the pipeline selection of new energy thermal management, if the use of improper/damaged hoses and/or hose joints will result in injury, the new energy thermal management is limited by the temperature, caliber, installation method, etc. Tube, metal insulation hose temperature range -60 ~ 250 ° C; pressure ≤ 2.5 bar. When the new energy thermal management configures the metal insulation hose and other pipelines carefully, when referring to its pressure and overpressure capability, caliber an...

Small environmental test chamber compressor should pay attention after maintenance
In the centrifugal small-scale environmental test chamber, the suction recovery device is generally an independent system, and if necessary, the pipeline connected to the condenser and the evaporator can be closed for separate maintenance. After replacing the compressor in the small environmental test chamber, the pumping recovery device generally uses the automatic mode to open, stop and work during the operation of the unit. Therefore, the oil level of the oil separator of the piston compre...

High temperature test equipment related troubleshooting
The high temperature test equipment is mostly caused by water shortage in the water circulation. This way, the purified water is replenished to the water tank until the water level meter on the lower right side of the water tank reaches about 80% of the entire scale. Every equipment will be fully commissioned before shipment. During the commissioning process, we have done ample tutorials for each internal system. If the equipment is in transit, due to up and down vibration, the float and the ...

Ultra-high temperature material cold and hot impact box refrigeration oil
The ultra-high temperature material impact test chamber test device has too much frozen oil in the evaporator, which can also cause insufficient cooling and cause slow cooling. The oil stored in the evaporator of the ultra-high temperature material impact test chamber test device can be directly judged by the hot and cold boundary line of the oil surface. If the oil level is too high, it should be released in time. Some Freon and refrigerating machine oil dissolve each other. Therefore, when ...

Common fuel cell environmental test device inspection method
During the cooling process of the fuel cell environmental test device, there is a chance of dripping inside. This is not a normal phenomenon used by the fuel cell environmental test device, but is caused by improper installation. After the fuel cell environmental test device is installed, test the machine (refrigeration) immediately. If there is no water leakage after running for a certain period of time, there will be no leakage problem. Of course, the installer can also be required to carry...
