Fully closed cycle high viscosity fluid refrigeration heating flow control system
Application:1. The tested object is connected to a test platform adapter.2. The internal parts of the parts are cooled, heated, flow controlled, and pressure controlled by various lubricating oils, hydraulic oils, aviation fuel, fuel oil, and coolant.3. The test component needs to go through a specific temperature profile and record the change in temperature.4. When conducting the tolerance test, perform the thermal shock test, and the rapid temperature drop control usually takes place in...

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 ...

Characteristics of the evaporator of LNEYA screw chiller
The amount of cooling capacity of the screw chiller is directly related to the energy consumption and operational economics of the entire unit, which is worthy of attention. Especially when designing a cold station, there is no single chiller in the general situation. This is mainly because when the screw chiller fails or is shut down for maintenance, it will not stop production. Instead, the reasonable unit should be selected according to the production situation. The number of units. When t...

Factors affecting cooling capacity during temperature control of battery test equipment
Battery Test Equipment Refrigeration System The greater the power of the battery test equipment compressor, the higher the cooling capacity. According to the size of the battery test equipment, the compressors of different types are selected. For example, the small battery test equipment is piston type, and the medium type is optional. Scroll type. When the water temperature of the battery test equipment (the evaporation temperature is different, the cooling capacity is different), the higher...
